[0002] During the processing of the double-pull front clip A in the related technology, a jig is needed to effectively position and fix the double-pull front clip A blank so that it can be processed. However, since all surfaces of the double-pull front clip A workpiece are blank casting surfaces, there are certain dimensional errors, which makes the double-pull front clip A workpiece prone to loose and unstable clamping during the clamping process, reducing the accuracy of the subsequent processing of the double-pull front clip A. Therefore, we proposed a double-pull front clip A processing jig to solve the above problems. Utility Model Content
