Abstract

This clamp assembly provides accurate four-point location of elements under a work station of a machine. No adjustments are required for uniform centering among a plurality of clamps. Each element is held positively to insure accurate centering. The clamping arms can be replaced without removing the apparatus from the work station. The clamp is adapted not to close beyond a selected point. Also it is adapted to center elements at a relatively high input rate without bounce in the elements.

Swivel Clamp Assembly

This clamp assembly provides accurate four-point location of elements under a work station of a machine. No adjustments are required for uniform centering among a plurality of clamps. Each element is held positively to insure accurate centering. The clamping arms can be replaced without removing the apparatus from the work station. The clamp is adapted not to close beyond a selected point. Also it is adapted to center elements at a relatively high input rate without bounce in the elements.

A pair of locating arms 2 is suitably driven to center a series of elements or work pieces successively relative to a work station not shown. The work pieces proceed along track 4 included in the assembly. Arms 2 are snapped into place on individual pivot bush assemblies 6.

Each assembly 6 is mounted on central post 8 and includes guide member 10 for engaging camming block 12. The latter is spring-loaded to hold arms 2 in a closed position. Block 12 includes pin member 14. This engages a shaft member 16 which is adapted to receive reciprocating motion.

In operation, the spring member holds block 12 in a position so that shaft member 16 extends beyond the assembly. When shaft member 16 is urged into the assembly, block 12 operates to rotate assemblies 6. Guides G attached to assemblies 6 rotate arms 2 to an open position. The rotation of assemblies 6 causes arms 2 to move away from one another. During this period the element to be centered can be moved into...
