公私合营上海新民机器厂技师吴根土,改进了一种刨爪形联轴器的装置,解决了刨床不能加工曲面工件的问题。该厂过去加工爪形联轴器的曲面,是用手工做,生产效率很低,质量也很难保证。现在采用吴根土改进的装置,在牛头刨床上自动走刀来刨削,提高了生产效率4倍。刨曲面的装置如图1,在牛头刨床的滑枕前部装一个齿条架。齿条架的下端有齿条,和齿轮咬合。齿轮用键销和螺杆固定在一起,螺杆装在套柱中。螺杆的槽内嵌有一个导块,这导块的另一端装在套柱的孔中。这样,当螺杆转动时,螺杆本身就会因导块的作用而上下移动。套柱用螺钉紧固在工作台上。工件
Public-private joint venture in Shanghai Xinmin Machinery Factory Wu Gentiao, improved a claw claw-shaped coupling device to solve the planer can not work on the curved surface of the workpiece. The factory in the past processing claw coupling surface, is done by hand, the production efficiency is very low, the quality is difficult to guarantee. Now using Wu root soil improvement device, automatic sharpening shaper on the shaper, raising the production efficiency of 4 times. Planing the surface of the device shown in Figure 1, in front of the shaper ram equipped with a racks. The lower end of the rack has a rack, and the gear bite. Gear with the key and screw fixed together, the screw installed in the column. A guide block is embedded in the slot of the screw, and the other end of the guide block is mounted in the hole of the sleeve. In this way, when the screw rotates, the screw itself will move up and down by the action of the guide block. Collars are bolted to the workbench. Workpiece
