在维修进口电动工具时,我们发现一些产品中的碳刷导线,用电阻焊方法直接焊在插片上,其工艺性、可靠性、经济性和内在质量均优于国内沿用的锡焊连接。图1是Makita 6105型6mm电钻中电阻焊连接的碳刷组件的示意图。图2是国内一些电动工具厂锡焊连接的碳刷组件的示意图。两者相比,可以看出前者的插片背部没有突出的锡团,不仅省了焊锡,而且内在质量好,总装时也方便省事许多。图3是Makita 6105型电钻碳刷组件装机后的示意图,插片套在刷盒外端部上并插于刷架内。
In the maintenance of imported power tools, we found that some of the products in the carbon brush wire, resistance welding method directly welded on the insert, its technology, reliability, economy and internal quality are better than the domestic use of soldered connections. Figure 1 is a schematic diagram of a resistance-welded carbon brush assembly in a Makita model 6105 6mm drill. Figure 2 is a schematic diagram of some domestic electric tools factory soldered carbon brush assembly. Compared with the two, it can be seen that the back of the former does not have a prominent tin back, which not only saves solder, but also has good inner quality and easy assembly when assembling. Figure 3 is Makita 6105 drill type carbon brush assembly installed schematic, insert the outer cover of the brush box and inserted in the brush holder.
