用换套法修复百分表中被磨损的上、下套筒时,旧铜套的拆卸较为麻烦。为此,我们利用报废的百分表测杆,自制了一个铜套拆卸工具,其结构见图1。使用时,把拆卸杆插入百分表套筒内,旋入顶杆,利用顶杆的锥面使拆卸杆槽口张开约1mm,拆卸杆端面顶住铜套端面,敲击拆卸杆,铜套就可方便地取出来。拆卸杆用废测量杆制作,在酒精喷灯上以约800℃的温度对需开槽部分进行局部退火,再用φ1.5mm钻头在测量杆15mm处钻一通孔,并在退火后的部位用锯条开槽,槽深15mm,然后进行淬火和回火处理,以防止使
Replacement method used to repair the dial worn in the upper and lower sleeve, the old copper sleeve removal is more troublesome. To this end, we use scrapped rod gauge, made a copper sleeve removal tool, the structure shown in Figure 1. Use, the demolition rod inserted into the dial sleeve, screwed into the mandrel, the demolition of the cone using the mandrel notch open about 1mm, demolition rod end to withstand copper end face, knocking demolition rod, copper Set can be easily removed. Disassembly rod with waste measuring rod production, the temperature of about 800 ℃ in the alcohol torch on the need to partially grooved annealing, and then use φ1.5mm drill bit in the measuring rod 15mm at a through hole, and in the annealed parts with a saw blade Slotted, groove depth 15mm, and then quenching and tempering to prevent
