Abstract
There is disclosed a gripper having improved cone and point jaw inserts wherein a single part can be used for both types of insert, thereby doubling the life thereof. Also disclosed is a simple insert retainer which can mount and secure a plurality of inserts with a single fastener, and a one-piece mount for universally mounting a gripper to a support bar using a single fastener.
Claims15
A pair of jaw inserts for a gripper having first and second insert retainers with holes therein adapted to be moved toward one another to grip a workpiece therebetween and away from one another to release said workpiece, said holes axially disposed perpendicular to said workpiece gripped between said retainers, each insert of each of said pair of inserts comprising:
- (a) a body adapted to be attached to either one of said retainers within one of said holes;
- (b) one end of said body being configured to engage one surface of said workpiece when mounted to said first retainer, said end being coaxially aligned with said body;
- and
- (c) the opposite end of said body being configured to engage the opposite surface of said workpiece when mounted to said second retainer, whereby said pair of inserts are both fully interchangeable and reversible between said retainers and each of said pair of inserts can therefore be used twice.
A jaw assembly for a gripper having first and second arms adapted to be moved toward and away from one another, said assembly comprising:
- (a) a retainer adapted to be mounted to either one of said arms;
- (b) a hole in said retainer;
- (c) a jaw insert disposed in said hole;
- (d) means defining a slot in said retainer extending from said hole;
- and
- (e) a fastener bridging said slot for clamping said insert in said hole.
A cone and point insert disengagably attachable to a powered gripper, said insert comprising:
- (a) a circular cylindrical body;
- (b) threads on the outside surface of said body;
- (c) a conical projection at one end of said body;
- and
- (d) a conical recess at the opposite end of said body.
