单件或小批量生产多头蜗杆,在没有专用设备的情况下要达到分头均匀操作是很繁琐的。为此,我们设计了多头螺纹分头器,除了解决自己维修机床用的模数m_s=3的四头、六头的蜗杆外,还为其它厂加工多头蜗杆,分头的均匀误差不超过0.02毫米,达到了设计要求。一、分头器的结构(见图) 分头器由锥柄1和键套2组成。制作时,先将键套用精度较高的拉刀加工出成品。然后锥柄毛坯加工到要求长度,两端打中心孔,右端花键部分按键套二分之一长度,外径大 Single or small batch production of long worm, without special equipment in the case to achieve uniform operation is very tedious. To this end, we designed a multi-head thread splitter, in addition to solving their own machine maintenance with the modulus m_s = 3 of the four heads, six heads of the worm, but also for processing other long worm, the uniform error of less than 0.02 mm, Reached the design requirements. First, the structure of the splitter (see Figure) Splitter consists of a taper shank 1 and the key set 2. Production, the first set of high precision broach used to process the finished product. Then the taper shank rough machining to the required length, both ends hit the center hole, the right end of the spline part of the key set length of the half, large outside diameter
