The invention relates to an
elevator accessory
machining device, in particular to a mechanical
machining device which comprises a base frame, a displacement plate
assembly, a rack fixing
assembly, anadjustable displacement
assembly, a height adjusting mechanism, an adjustable
cutting mechanism and
scrap clearing mechanisms. The displacement plate assembly is fixedly installed on the base frame. The rack fixing assembly is installed on the base frame in a sliding manner. The adjustable displacement assembly is fixedly installed on the rack fixing assembly. The height adjusting mechanism is fixedly installed on the base frame. The adjustable
cutting mechanism is installed on the height adjusting mechanism in a sliding manner. The
scrap clearing mechanisms are fixedly installed at the two ends of the height adjusting mechanism correspondingly. The mechanical
machining device has a function of carrying out adjusting according to different specifications of machined racks, meanwhile, the device also has a function of adjusting the opening
diameter of a cutter, production cost increase caused by cutter replacing is avoided, the device further has a
scrap clearing function, and the situation that scraps enter the device, and are generated is prevented.
