目前从美国MULTI-ARC公司引进的多弧涂层设备,其卡具为刺猬式结构,钻头只能随该卡具作公转运转,对于小钻头来说,其装炉量将受到一定的限制(见图1中钻头装卡位置)。通过图2的改造,可以使装卡钻头随卡具自转的同时绕中心轴公转,从而提高单炉生产效率,而且卡具制作简单。图1为刺猬式卡具平而图,图2为改造后的行星式卡具平面示意图。 At present, multi-arc coating equipment imported from MULTI-ARC Company of the United States has a hedgehog structure, and the drill bit can only revolve with the chuck. For a small bit, the amount of furnace loading will be limited See Figure 1 bit loading position). Through the modification of FIG. 2, the loading bit can be rotated around the central axis with the rotation of the chuck, so as to improve the production efficiency of a single furnace, and the fixture is simple to manufacture. Figure 1 is a hedgehog flat with the map, Figure 2 is a schematic plan of the modified planetary fixture.
