上海沪东造船厂近年来对柴油机零部件的滚轮导筒采用车夹具加工新工艺,产品质量和经济效益稳步提高。过去加工这种零部件,大都采用组合镗夹具加工,垂直度、对称度不能满足公差范围。通过对镗夹具(立、卧)、车夹具、座标镗几种夹具在达到的垂直度、对称度、成本、效率等方面的综合评价,得出车夹具是目前最为理想的一种工具。该厂有关人员对车夹具进行多次正交试验,确定车夹具合理的定位基准和压紧位置,根据试验数据进行车削实际操作试车,对各种存在的问题分别落实具体措施,如对调试误差采取根据检验所得实
Shanghai Hudong Shipyard in recent years on the wheel parts of the wheel guide drum cart processing new technology, product quality and economic efficiency improved steadily. In the past processing of such parts, most of the combination boring jig processing, verticality, symmetry can not meet the tolerance range. Through the comprehensive evaluation on the verticality, symmetry, cost and efficiency of the boring fixture (vertical and horizontal), vehicle fixture and coordinate boring fixture, it is concluded that the vehicle fixture is the most ideal tool at present. The factory personnel on the car fixture for many orthogonal test to determine the car fixture with a reasonable basis for the positioning and clamping position, according to the test data actual operation of the turning test, the various problems exist to implement specific measures, such as debugging error Taken according to the test results
