摘　　要：对CA6136卧式车床长期使用和研究发现前置刀架定位精度和耐冲击性较差,发生撞刀或受到冲击,很容易卡死,强行搬动刀架拉杆换刀,拉杆会折断以致损坏机床部件,后续维修较难。为延长刀架使用寿命,很有必要对其定位方式进行研究和改进。分析后提出3种改进方案,经过结构设计、受力分析和对比研究后选定最优方案。通过机械加工、装配和调试等过程完成改进,经长期测试能达到理想效果。该研究成果值得机床厂家参考和使用。After long-term use and research on CA6136 horizontal lathe,it is found that the positioning accuracy and impact resistance of the front tool rest are poor,and it is easy to get stuck in case of tool collision or impact.If you forcibly move the tool rest pull rod to change the tool,the pull rod will break and damage the machine tool parts,making subsequent maintenance difficult.In order to prolong the service life of the tool rest,it is necessary to study and improve its positioning mode.After analysis,three improvement schemes are proposed,and the optimal scheme is selected after structural design,force analysis and comparative study.The improvement is completed through machining,assembly and debugging,and the ideal effect can be achieved through long-term testing.The research results are worth reference and use for machine tool manufacturers.
