我厂产品有一类零件如图1所示。此类零件及其刻线特点有三:一是有多种尺寸规格(d为115～345mm、H为28～50mm);二是刻线每格1°,在半圆周180个分度中要刻0～180°共181条线,为提高工效,主轴转一转,应能加工出两个工件。而机床主轴应在圆周360个分度中,刻出两个工件上总数为362条刻线;三是工艺要求刻线深度0.4mm。采用通用圆刻线机,效果不太理勰。今介绍自制圆刻线机,供参考。
I have a factory product parts shown in Figure 1. There are three such parts and their engraved features: First, there are a variety of sizes (d is 115 ~ 345mm, H is 28 ~ 50mm); the second is engraved line every 1 °, 180 semi-circle 0 ~ 180 ° a total of 181 lines, in order to improve ergonomics, spindle turn, should be able to work out two workpieces. The spindle of the machine should be divided into 360 degrees in the circumference, carved out a total of 362 lines on two workpieces; Third, the process requirements engraved depth of 0.4mm. Universal Circular engraving machine, the effect is not reasonable 勰. Introduce homemade circular groove machine for reference.
