The double-headed motor The upper and lower ends of the 17 are fixedly installed with a grinding disc 18, the top of the working plate 9 is movably connected with a rotating plate 19, the top of the working plate 9 is embedded with a motor and fixedly connected to the rotating plate 19, and the middle of the top of the rotating plate 19 is fixedly installed with a connection. The seat 20, the middle part of the top of the connecting seat 20 is fixedly welded with a threaded column 21, and the upper part of the threaded column 21 is threadedly connected with a processing piece 22.

Among them, the two grinding discs 18 on the double-head motor 17 are not the same size, the size of the upper grinding disc 18 is larger than that of the lower grinding disc 18, the upper part receives the largest force during the cutting process, and the burr is often the most severe during cutting, and The lower part is relatively flat, so the upper grinding disc 18 is set larger, and the lower part is smaller, which saves resources to the greatest extent.

Among them, the upper part of the clamping plate 15 has four fixed lobes, and the lower part of the clamping plate 15 is a hollow cylinder, and the clamping plate 15 can be rotated at will. If the position is blocked, when the workpiece 22 is placed, turn the double-headed motor 17 over, and fix the four lobes with bolts at the same time.

Among them, the two sides of the bottom of the work plate 9 are provided with chute, and the chute of the work plate 9 is matched with the slide rail 12. The size of the workpiece 22 on the work plate 9 will inevitably be different in size.
