[0002] With the continuous development of lithium ion batteries, the requirements for battery testing are becoming higher and higher. The traditional scheme of testing by using PoGo Pin probes cannot meet the requirements of high testing efficiency. To solve this problem, a new scheme of testing by using elastic sheet needles has emerged, but the elastic sheet needles are very small, with a thickness of only 0.15 mm. Correspondingly, the matching parts for installing the elastic sheet needles are also very small. For the machining of small parts, machining precision is crucial. When machining the matching parts for installing the elastic sheet needles, double-sided machining is required for the workpiece. When using the existing clamp to turn over, the workpiece needs to be disassembled first, and then assembled after turning over. This method has high labor cost and low operation efficiency, and multiple clamping will also change the clamping position of the workpiece on the clamp, making it difficult to ensure good machining precision.
