摘　　要：弹簧夹头作为定位夹具,装夹简单、快捷,且重复定位性能好,是机械加工行业尤其轴承加工行业中最常用的定位夹具。受机床加工范围的限制,一台机床只能加工相应尺寸范围内的零件。为了实现在现有设备上扩大加工范围,在原弹簧夹头的前端连接一个过渡件并铣出涨缩槽,完成对弹簧夹头的改进。采用改进后的弹簧夹头对不同外径的轴承零件进行加工验证,实际检验结果证明:该改进方式简单经济,改进后的弹簧夹头使用性能好,便于不同外径轴套类零件的加工,被加工零件尺寸稳定。As a positioning jig,the collet chuck is simple and fast in clamping,and has good repetitive positioning.It is commonly used in the machining industry,especially in the bearing processing industry.Limited by the scope of machine processing,a machine can only process parts within the corresponding size range.In order to expand the processing range on the existing equipment,a transition piece is connected to the front end of the collet chuck and the expansion and shrinkage grooves are milled to complete the improvement of the collet.The improved collet chuck is used to process and verify the bearing parts with different outer diameters.The actual inspection results show that the improved method is simple and economical,the improved collet chuck has good performance,and is convenient for the processing of parts with different outer diameters.The processed parts are dimensionally stable.
