During the process of placing the workpiece, the workpiece is pre-positioned by the fool-proof mechanism in the workpiece fixing fixture mechanism, wherein the fool-proof rod 3 in the fool-proof mechanism pre-positions the non-processing area on different sides of the workpiece to ensure that the workpiece swings The accuracy and speed of the placement are improved, and the work efficiency of the workpiece production process is improved. At the same time, the workpiece is angularly positioned by the angular positioning mechanism, so that the lateral position of the workpiece is determined and fixed. In this process, according to the specific shape and structure of some control arm workpieces, it is divided into three fixed fulcrums, so that after the three fixed fulcrums are laterally fixed, the workpiece will not be displaced laterally, and the workpiece processing will be ensured. stability and accuracy. Specifically, the first angular pin seats 4 are two groups of the same structure, and the workpiece is angularly positioned by contacting two adjacent side surfaces of the first end of the workpiece; the second angular pin seats 5 are two groups of the same structure. Group and angularly position the workpiece by contacting two adjacent side surfaces of the second end in the workpiece; and a third pin seat 6, positioning the workpiece by contacting the side surface of the middle portion of the workpiece. The first angular pin seat 4 , the second angular pin seat 5 and the third pin seat 6 fix the workpiece laterally by contacting the side surfaces of the workpiece in different directions.
