在车床维修中,经常遇到如何合理地配作丝杆的螺母。我厂针对这个问题,改进了测量螺母中心的方法,并制造了一套车螺母可调夹具。该夹具简单、可靠。图1为中心测量方法,公式x=H-h+D/2。此测量要在中拖板、大拖板修复情况下进行。夹具装配见图2。定位小角铁10与主轴中心线相重合,调节螺杆5,使工件角铁4调整到加工螺母需要的中心尺寸,即x值。然后,装入工件,横向使工件对称线与主轴中心相重合,最后压紧,即可加工。
In the lathe repair, often encountered how to rationally screw nut. In response to this problem, our factory improved the method of measuring the center of the nut and manufactured a set of adjustable nut and fixture. The fixture is simple and reliable. Figure 1 for the center of measurement methods, the formula x = H-h + D / 2. This measurement should be carried out in the drag plate, large carriage repair case. Fixture assembly shown in Figure 2. Positioning small angle 10 coincides with the centerline of the spindle, adjusting the screw 5, the workpiece angle iron 4 is adjusted to the processing center nut size, ie, x value. Then, into the workpiece, the horizontal symmetry of the workpiece line coincides with the spindle center, the final compression, you can process.
