Abstract

In this pin vise assembly, a cam mechanism stabilizes the vise for automatic opening and closing of the vise for insertion of samples. The assembly includes vertical chuck support 1 adapted at one end with head 7 for connection to gauge 2. Support 1 is provided at its other end with chuck sleeve 3 and housing vise members 4 into which are removably inserted and clamped test samples, such as pin 5 of a module during strain testing.

Automatic Pin Vise

In this pin vise assembly, a cam mechanism stabilizes the vise for automatic opening and closing of the vise for insertion of samples. The assembly includes vertical chuck support 1 adapted at one end with head 7 for connection to gauge
2. Support 1 is provided at its other end with chuck sleeve 3 and housing vise members 4 into which are removably inserted and clamped test samples, such as pin 5 of a module during strain testing.

Sleeve 3 is mounted on support 1 for limited rotational and vertical reciprocable movement. Sleeve 3 is normally biased to its extended form by coil spring 6. Reciprocating and rotating movements are limited by L-shaped tracking slot 8 mounted about guide pin 9 extending radially from support 1.

Movement of sleeve 3 is effected by engagement of its drive pin 10 with drive face 11 of rocking arm 12 pivoted by reversably rotatable drive shaft 13 on which is mounted cam 14. The latter includes a low profile 15 and a high profile 16 for actuating elongated cam follower 17 into and out of engagement with circumferential groove 18 in support head 7. Follower 17 is biased against the cam 14 profile by coil spring 19 mounted between collar 20 on follower 17 and seat 21 formed on frame 22. Follower 17 is recessed at 23 so that, as follower 17 moves along the low profile 15 of cam 14, there is disengagement with groove 18 of head 7.

With shaft 13 rotated clockwise to the closed position, arm 12 is disengaged from pin 10 so that...
