Device for improving turning height deflection of ball cage holder

The utility model relates to the field of lathe machining jigs, in particular to a device for improving turning height deflection of a ball cage holder, which comprises a pull rod, an ejector rod, a collet shell and an inner collet. The collet shell is provided with a through hole, the pull rod is used for pulling the ejector rod to move in the through hole, and the ejector rod is provided with a conical abutting face. One end of the inner collet chuck is arranged in the through hole, the inner collet chuck is provided with a conical hole abutting against the conical abutting face, and the other end of the inner collet chuck is provided with a step clamping face used for clamping a workpiece. According to the device for improving turning height deflection of the ball cage holder, the workpiece clamping stability is enhanced, and instability and deflection of the turning height of the holder are avoided. 本实用新型涉及车床加工治具领域，尤其涉及一种用于改善球笼保持架车削高度偏斜的装置，包括拉杆、顶杆、筒夹壳和内筒夹；所述筒夹壳设有通孔，所述拉杆用于拉动顶杆在通孔中移动，所述顶杆设有锥形顶靠面；所述内筒夹的一端设置在
