Abstract

The invention provides a work gripping device which positions and grips the work by using supporting shafts protrusively provided on both side surfaces of the work. The work gripping device is protrusively provided with the supporting shafts on both side surfaces, and grips the work. A pair of gripping arms 12 is attached to a device frame 1 so as to be opened / closed. Arm actuating means capable of opening / closing these gripping arms 12 are provided. At a end portion the gripping arm 12, a large diameter hole 24 in which the supporting shaft 10 is loosely inserted, and a positioning hole 25 communicating to a lower part of the large diameter hole 24 and applicable to the supporting shaft 10 are provided. After both gripping arms 12 are closed while the supporting shaft 10 is gradually inserted in the large diameter hole 24, if both gripping arms 12 are raised up, the supporting shaft 10 is moved from the large diameter hole 24 to the positioning holes 24, 25.

Description

technical field [0001] The present invention relates to a workpiece clamping device used when clamping, lifting and transferring a workpiece to a predetermined position, and more particularly relates to a clamping device for determining the position of a workpiece by using support shafts protruding from both sides of the workpiece Workholding device. Background technique [0002] When gripping, lifting, and transferring a workpiece to a specified position, the relative position between the workpiece and the gripper arm must be constant. Therefore, in the prior art, as described in Patent Document 1 below, when a workpiece is clamped by a clamping device, a positioning pin provided on the clamping device is inserted into a positioning hole on the workpiece. [0003] Patent Document 1 [0004] Japanese Patent Application Publication No. 10-120146 [0005] But, on the workpiece that does not have positioning hole, can not use above-mentioned existing clamping device.
