百分表的铜套,因磨损需要调换时,我们采用如图所示的拆卸工具,操作方便、可靠,效率也大为提高,制作亦很简便。使用方法:1.将拉杆4放在套筒1孔里,靠紧在铜套2的端面上.2.把衬套3套在套筒1上,抵紧。3.装上螺母5并旋动之,使铜套随拉杆的提升而徐徐进入衬套的过门孔内。此工具的缺点是:1.不能通用(测杆外径大小不一)。2.旋动螺母费劲较大(螺母外径可加大)。3.拆卸时若是打转,可用测杆顶住拉杆端面,增加摩擦力。
Due to wear and tear need to change the copper sets, we use the removal tool shown in the figure, easy to operate, reliable, greatly improved efficiency, the production is also very simple. Usage: 1. The rod 4 on the sleeve 1 hole, close to the end of the copper sleeve 2. 2. Set the sleeve 3 sleeve 1, tight. 3. Install the nut 5 and rotate it, so that the copper sleeve with the lifting rod and slowly into the bushing of the door hole. The shortcomings of this tool are: 1. Can not be universal (rod diameter different sizes). 2 screw nut hard (nut diameter can be increased). 3. If the demolition is spinning, the test rod can withstand the rod end, increasing friction.
