Dixi-57型坐标镗床系瑞士Dixi公司在60型卧镗的结构基础上,加以改进的。该机床精度高,具有优良的加工性能和多用性等特点。我们在使用和修理中,总结了Dixi-75型卧镗几种常见故障的排除方法,现介绍如下: 一、工作台锁紧机构失灵排除故障的方法(见图1): (1)拔出工作台丁字槽内的二个孔盖;(2)松开螺钉1;(3)将锁紧块2向锁紧齿轮3靠拢,使锁紧块2的尖斜面与轮槽面的间隙保持在0.05mm内,然后紧固螺钉1;(4)当采用上述方法无效时可旋下螺钉1,吊起台面,检查锁紧块与回转面的接触有否磨损再进行修复。二、滑板锁紧机构失灵
Dixi-57-type jig boring machine is the Swiss Dixi company in 60 horizontal boring structure based on the improvement. The high precision machine, with excellent processing properties and versatility and so on. We use and repair, summed up the Dixi-75 horizontal boring several common troubleshooting, are described below: First, the table locking mechanism failure troubleshooting (see Figure 1): (1) pull out (2) Loosen the screw 1; (3) Close the locking block 2 to the locking gear 3, so as to keep the clearance between the beveled surface of the locking block 2 and the groove surface 0.05mm, and then tighten the screw 1; (4) When using the above method is invalid, screw 1 can be unscrewed, lifting table, check the locking block and the rotary contact surface wear and then repair. Second, slide locking mechanism failure
