车床丝杠(光杠)在总装时,有一项a、b面对床身导轨面的等高平行性精度要求。我厂在生产C6136A型车床和修理各种车床时,制成了几套如图所示的丝杠(光杠)总装精度校验工具。经过长期使用证明,效果很好。这种工具结构简单,制造容易,使用方便。开槽夹紧块17,通过六角螺钉与移动块18紧固在一起,并用螺钉16紧固在长、短垂直杆15、19上。长、短垂直杆随同夹紧块11用螺钉3紧固在横向杆12上。螺杆10旋紧在滑板2中,靠螺母9压紧圆球8(圆球8与横向杆12可看作一体)。使用时,将模具按图所示放在床身一端的导轨面上,两只千分表分别插入开槽夹紧块17的孔内,并用螺钉16夹紧,然后用手旋转滚花手把5,螺杆6便拉动螺杆10,使滑板2在模体燕尾1上作直线移动,使千分表触头与
Lathe screw (light bar) in the assembly, there is a a, b to face the bed rail surface contour parallelism accuracy requirements. I plant in the production of C6136A lathe and repair all kinds of lathes, made of several sets as shown in the screw (light bar) assembly accuracy verification tool. After long-term use proved effective. The utility model has the advantages of simple structure, easy manufacture and convenient use. The slotted clamping block 17 is fastened to the moving block 18 by means of hexagonal screws and fastened by screws 16 to the long and short vertical rods 15, The long and short vertical rods are fastened to the transverse bar 12 with screws 3 along with the clamping block 11. The screw 10 is screwed in the sliding plate 2, and the ball 8 is pressed against the nut 9 (the ball 8 and the horizontal rod 12 can be regarded as one piece). When in use, place the mold on the rail surface at one end of the bed as shown in the figure, insert the two dial indicators into the holes of the slotted clamping block 17 and clamp them with the screws 16, then rotate the knurled handle 5, the screw 6 will pull the screw 10, so that skateboard 2 in the body dovetail 1 for a straight line so that the contact with the indicator
