在车床上用一般的方法来加工较大的薄壁工件时,要避免工件变形是比较困难的。如果采用图1的工具,就能避免薄壁工件的变形。图1中,1是生铁盘,中心有孔。盘的周边上有四个螺纹孔(90°分布),旋入螺钉2。螺钉2上带有托块3,托块3是用销钉4支持在螺钉头部的。工作时,根据工件的孔径,将螺钉2调节到适当的位置,然后装在工件的孔中。利用这种工具来加工薄壁工件的情形如图2。
In the lathe in the general method of processing larger thin-walled parts, to avoid deformation of the workpiece is more difficult. If you use the tool in Figure 1, you can avoid the deformation of thin-walled workpiece. Figure 1, 1 is a pig iron plate, the center hole. There are four tapped holes on the periphery of the disc (90 ° distribution) and screws 2 in. The screw 2 is provided with a supporting block 3, which is supported by the pin 4 on the head of the screw. Work, according to the workpiece aperture, the screw 2 to adjust to the appropriate location, and then installed in the workpiece hole. The use of such tools to process thin-walled parts of the situation in Figure 2.
