加工或修理车床床身时,可在龙门磨床上使用图示夹具进行安装、调整和夹紧。夹具体300×300(毫米),借助螺钉4可使1:10的斜铁沿导向槽2移动。螺钉4的螺距是2毫米,螺钉每转1/4转,可使工件上升或下降0.05毫米。全行程的升降量是10毫米。在导轨磨床上使用四个这样的夹具,就可以校正工件的水平和垂直平面。找正后,通过 When machining or repairing a lathe bed, use the illustrated fixture on the gantry grinder for installation, adjustment and clamping. The clamp is 300 × 300 (mm) and a 1:10 skew iron is moved along the guide groove 2 by means of the screw 4. The pitch of screw 4 is 2 mm and the screw rotates 1/4 turn to raise or lower the workpiece by 0.05 mm. The full stroke is 10 mm. Using four such jigs on the rail grinder, you can correct the horizontal and vertical planes of the workpiece. After the correction, through
