我厂生产的钢筋校直切断机,在转肖离合器中有一个刹刀零件(见图1)。该零件的螺旋面加工,长期来是个难题。过去,我们靠划线及粗刨后再由钳工修正。这种加工方法,工效低劳动强度大,加工后的螺旋面精度不高。为此,我们设计制做了一套螺旋面的车削装置。经过实际使用证明,此装置是成功的,它具有下述特点: 1.结构简单,在普通车床上安装使用时,
Steel bar straightening and cutting machine I produced in our factory has a brake cutter part in the rotating shaft clutch (see Fig. 1). The spiral surface processing of this part has long been a problem. In the past, we were aided by fitters after scribing and roughing. This method of processing, labor-intensive low labor intensity, processing accuracy of helical surface is not high. To this end, we designed a set of spiral surface turning device. After the actual use of proof that this device is successful, it has the following characteristics: 1. Simple structure, the use of ordinary lathe installation,
