车床的断屑问题是实现自动加工过程的关键。在车削中出现连续切屑,轻者切屑缠绕使加工无法进行,重者会发生设备或人身事故。针对这个问题,我们研制了用于车床主轴的断屑静压轴承。这种轴承可使主轴在工作中产生轴向振动,使之既不影响被加工零件的径向尺寸,又促使切屑裂断,从而保证了车床的加工循环能够正常进行,无需经常停车人工处理缠绕切屑。一、工作原理如图1所示,断屑静压轴承的调压元件是薄膜反馈节流器,在两个对置的节流凸台上缠绕电磁线圈2、其两端连接36伏交流电源,可调电位器(可变电阻3)可以
The problem of chip breaking in lathes is the key to automating the process. Continuous turning appears in the turning chip, the light chip winding process can not be carried out, in serious cases there will be equipment or personal accident. In response to this problem, we developed a chip breaking hydrostatic bearings for lathe spindles. This bearing can make the spindle in the work of axial vibration, so that it will not affect the radial size of the processed parts, but also promote the chip rupture, thus ensuring the lathe machining cycle can be normal, without frequent manual stop manual winding Chip. First, the working principle shown in Figure 1, the pressure-relief components of the chip breaking hydrostatic bearings are thin-film feedback throttling, electromagnetic coil 2 is wound on two opposed throttling boss, the two ends of which are connected with 36V AC power Adjustable potentiometer (variable resistor 3) Yes
