UNILOCK Modular Workholding System Vol 4

UNILOCK multi-axis workholding products are designed to provide flexibility and functionality for 5-axis machining and 5-sided machining via multiple-part transfers. We also offer solutions for machines with retrofit 4th/5th axis tables. BIG DAISHOWA can help you to maximize the benefits of your machine design through efficient workholding. These CNC workholding fixtures locate and stabilize the workpieces without obstructing access to the top and sides of the part. They also allow a clamped workpiece to be flipped into new orientations for subsequent machining operations without unclamping it from the workholding.

OVERVIEW

HOW IT WORKS UNILOCK utilizes spring pressure to drive multiple clamping pins against a tapered clamping knob. Air pressure is used to compress the springs to back the clamping pins off of the clamping knob. This clamping process is achieved by bleeding the air pressure out of the chuck. To facilitate palletization, the clamping knob is attached to a base plate, fixture or directly to a workpiece. The result is quick and repeatable clamping. A hand locking version (no air required) is also available.

FEATURES • Clamping mechanism: heavy-duty die springs • Chuck opening: air pressure to compress springs • Clamping stability: low profile with matching taper wedges • Positional accuracy: adaptable to workpiece conformation • Unlocking air pressure: 75 PSI • Turbo assist clamping

SINGLE CHUCK APPLICATIONS The UNILOCK clamping knob mates with the central taper in the chuck to establish the centerline location (XY reference in a cartesian coordinate system). A timing pin or key locates in a notch or bushing to orient the coordinate system relative to XY and to restrict rotation. The Z reference in this same coordinate system is established by the bottom of the fixture or workpiece contacting the top ground surfaces of the chuck. These same mating surfaces (bottom of the fixture and top of the chuck) will control axial alignment. The clamping knob can be used for locking down a workpiece without influencing location if external features are used for positioning.

MULTIPLE CHUCK APPLICATIONS UNILOCK is not restricted to one clamping knob. When the fixture or workpiece exceeds the work range of a single UNILOCK chuck, additional clamping knobs and chucks can be used to provide the necessary support and stability required for the process. There are only a few limiting factors as to the size of an array of chucks or in the weight of a workpiece. Undersized knobs provide clearance for large parts or out-of-position locations.

DESIGNED FOR MANUFACTURING During day-to-day use, chucks can be cleaned with compressed air. The fit between the clamping rams and the chuck body will not allow air pressure to push chips inside of the chuck. If you get chips in the clamping pocket, simply blow them out with an air gun. When open, the wedges completely retract. The one-to-one length-to-diameter ratio of the pocket is easily cleaned. There is no need for a vacuum. The 40mm tall by 40mm diameter clamping knob is extremely stable and can double as a foot when moving fixtures and workpieces around the shop. You will not need protective sleeves or special shelving when storing or transporting UNILOCK palletized fixtures or workpieces. Male and female threads are available in multiple sizes.

SELF-GUIDING DESIGN

23º

4.8mm

UNILOCK is designed to accept warped workpieces and fixtures. The shallow clamping pocket will allow a clamping knob to enter the chuck at an angle of up to 23 degrees. Undersized clamping knobs are also available. Standard and special UNILOCK clamping knobs will accommodate your out-of-position datums.

The radius on the smaller bottom diameter of the clamping knob addresses out-of-position loading conditions. When working with large workpieces that can warp, expand or contract, the knob can be used to help guide the clamping knobs to the center of the chuck.

OVERVIEW

PROCESS YOUR WAY TO SAVINGS Fixtures and workpieces are easily adapted to UNILOCK clamping knobs. Tremendous savings are available if the fixture or workpiece can be reoriented or transferred to machine additional features while remaining attached to the UNILOCK clamping components. On horizontal machines with columns, fixtures can be rotated 90 degrees or moved to the top. Transferring fixtured parts through as many operations as possible eliminates additional fixtures and clamping/unclamping time. Less clamping and unclamping of parts also reduces scrap and improves feature-to-feature accuracies.

TRANSFER WORKPIECES BETWEEN PROCESSES • Vertical machining cells • Horizontal machining cells • High-speed drilling and tapping centers

• Surface and cylindrical grinding cells • Horizontal and vertical lathes • Coordinate measuring cells

Once you grab the part, use UNILOCK to send it to as many operations as possible without removing the part from the fixture. UNILOCK positions and clamps from one face, leaving the other faces available for machining. Rotary tables, angle/sine plates and multi-sided tombstones facilitate part reorientation for subsequent operations.

The user can expand the operational envelope of any UNILOCK chuck by adding external timing features and support for the portion of the workpiece or pallet that falls outside of the top of the chuck.

OVERVIEW

WORKING SOLUTIONS IN MINUTES Table chucks are mounted to base plates and are ready to be clamped to your workstation. These chucks are supported by preassembled pallets. Shown below are the Mono, Duo and Quad table chucks, along with their pallets. Pneumatic kits are also available to install a working solution in minutes.

BUILD YOUR OWN CUSTOM SOLUTIONS UNILOCK components can be purchased individually for incorporation into your own custom designs.

APPLICATION EXAMPLES

SCHEDULING FLEXIBILITY AND SETUP VERSATILITY A Clamping System Flexible Enough to Change the Entire Table or Workpieces and Fixtures UNILOCK establishes predefined datums on all of your machines. When you load, lock and hit cycle start, there is no wasted time. A setup should always take the same amount of time. UNILOCK delivers scheduling flexibility and setup versatility. By using more than one chuck on a machine, you will be able to switch between multiple small parts or fewer large parts. Our predefined datums allow you to quickly and accurately convert your machining center from a headstock and tailstock setup to fixtures on the table.

USE IN ANY CONFIGURATION AND PROCESS Applications Are Endless – Limited Only by Your Imagination Align all of your rotary table fixtures in seconds. As you move away from the spindle nose, UNILOCK’s heavy-duty chucks will absorb the additional leverage and torque. Since individual UNILOCK components are sold separately, you can build specific solutions in-house or contact your tool and fixture provider. UNILOCK can be used in any configuration in almost any process. A heavy cut requiring six chucks to stabilize the part for machining can be accurately positioned on a coordinate measuring machine with two small chucks or a single chuck and a timing feature.

APPLICATION EXAMPLES

LARGE PARTS Save Money on Your Next Job

UNILOCK provides undersized clamping knobs so you do not have to hold .0004" on fixture locations when your production tolerance is .005". These undersized knobs are a necessity to mount knobs directly to warped or loosely toleranced workpieces. If you do not need to, or cannot hold a tight tolerance, simply select the appropriate undersized clamping knobs to accommodate the workpiece or fixture. UNILOCK’s heavy-duty clamping knobs are a necessity when you are using a hoist to load and unload your machine. With a length-to-diameter ratio of 1-to-1, UNILOCK’s 40mm clamping knob can be left on fixtures and workpieces without worry of damage during loading and unloading, storage or transfer.

SBA = Establishes centerline SBB = Orients about centerline SBC = Clamp only, no positioning • See pg. 40 for more details on knob functions

SMALL PARTS Remove Process Time – Save More Than Just Setup Time Before UNILOCK, three subsequent machining processes required the operator to clamp and unclamp the part three times. Now the same part is only clamped and unclamped once for these same three processes. Even when the time spent clamping and unclamping the part is minimal, it creates unnecessary labor and a chance for errors. Use UNILOCK to immediately increase spindle uptime and decrease scrap due to part positioning and clamping errors. If a part has to be clamped and unclamped in a different fixture for each operation, considerable process time and money can be saved by leaving the part in the same fixture for as many operations as possible. This also eliminates expensive fixtures on subsequent operations.

ERGO 138 — WELDING Four ERGO E600 bases are used to hold welding fixtures, allowing for the quick changeover of fixtures when the production changes from one series of parts to another. There is no need to retouch points between changes as the system repeatability of .005 μm (.0002") is greater then needed in most welding applications.

ERGO 138 — TIMING BLOCK The ERGO E100 base can be modified by the end user to accept a timing block allowing for the timing of smaller fixtures at 45° or 135°. The ERGO E100 V1 and V2 bases offers a 45° timing block mount with no modification. The V1 also has a single 14mm H7 timing notch. In all cases the block ( 15.270.331 ) is sold separately.

KNOBS, BALLS AND PALLETS

CLAMPING KNOBS Can be attached to fixtures or directly to workpieces. Our standard knobs can be mounted in a blind hole from the bottom or pulled up from the top. Standard clamping knobs accept the following: OPTION 1: PASS-THROUGH BOLT – The bolt is inserted past the clamping knob and threads into the workpiece or fixture. OPTION 2: CAPTIVE SET SCREW – The set screw is captivated between the knob and the workpiece or fixture. OPTION 3: RETAIN FROM TOP – The bolt passes through the workpiece or fixture and pulls the knob into position.

OPTION 1: PASS-THROUGH BOLT

OPTION 2: CAPTIVE SET SCREW

OPTION 3: RETAIN FROM TOP

Option 2 not recommended for B Type. ! CAUTION

Standard clamping knobs have a metric positioning boss which is Ø25mm and ground to a fit of h6. This boss is 5mm tall. The overall measurements of the clamping knob is Ø40mm by 40mm tall.

The SBA Knob is ground to fit with the center ground taper of the chuck. This fit establishes centerline location. This location will repeat to better than +/-.0002" (.005mm).

The SBB Knob is ground like a diamond pin and orients your work relative to the centerline of the SBA Knob.

The SBC Knob is ground undersize. It will bring the bottom of the workpiece or fixture down on the top of the UNILOCK chuck.

5-AXIS SYSTEMS When and Where You Need It

If your optimal work zone is directly over the center of the machine table, our low-profile grid plates with integrated UNILOCK zero-point clamping systems are available, out of the box, as turnkey solutions. By offering cap screw and dowel pin technology intermixed with zero-point UNILOCK chucks, our base plates allow you to quickly load virtually any workholding product, including 5-axis vises and dovetail clamping solutions. If the workpiece needs to be elevated above the table and that feature is not built into the workholding component, UNILOCK can be used to raise the workholding or the workpiece. UNILOCK clamping knobs can also be attached directly to the bottom of the workpieces and within 25mm of the machining edge. UNILOCK zero-point clamping chucks can also be surface mounted directly to the machine table. With an overall height of 46mm, the UNILOCK ASM 146 and ISM 160 chucks are excellent candidates when you need to quickly bolt on a quick-change UNILOCK receiver. Our 5-axis clamping products, UNIVICE SYNCHRO, UNICLAMP and FIRST GRIP can also be directly affixed to a machine table, a grid plate or processed in UNILOCK chucks.

5-AXIS SYSTEM 40 UNILOCK Riser Chucks, Extensions & Reductions

UNILOCK riser chucks have a working diameter of 80mm. They are available on base plates or as stacking modules in heights of 75mm and 100mm. Base plate chucks have Ø12mm dowel pin holes that locate chucks on 40mm and 50mm grid patterns. Base chucks can also have clamping knobs attached for use in other UNILOCK chucks, or the stacking version can be used for elevation and clearance. All chucks open and close quickly with a single hex key. The chucks are all capable of clamping any UNILOCK SYSTEM 40 clamping knob (40mm). By using a riser assembly, workpieces can be clamped 40mm from their edge. Extensions allow the clamping knob to be anchored 25mm from the workpiece edge. Extensions reduce the working diameter from 80mm to 50mm and add an additional elevation of 25mm or 50mm.
