When the brake drum 500 is placed on the positioning plate 200 and the center line of the through hole 510 of the brake drum 500 is collinear with the center line of the positioning hole 210, the drill through holes 220 are respectively aligned with the drilling positions of one brake drum 500.

The clamping assembly includes a connecting rod 320 and a clamping rod 310. One end of the connecting rod 320 is slidably connected to the base 100, so that the connecting rod 320 can be lifted and lowered along the vertical direction. For convenience of use, an air cylinder or a motor is used to drive the lifting of the connecting rod 320. The clamping rod 310 is vertically connected to the connecting rod 320, the clamping rod 310 is located right above the positioning hole 210, and the center line of the clamping rod 310 is collinear with the center line of the positioning hole 210. The end of the clamping rod 310 adjacent to the positioning hole 210 is tapered. The diameter of the large-diameter end of the tapered end of the clamping lever 310 is larger than the diameter of the through hole 510 of the brake drum 500.

The utility model discloses during the use: the brake drum 500 is placed on the positioning plate 200, and the mounting surface of the brake drum is tightly attached to the upper plate surface of the positioning plate 200. At this time, the through-hole 510 of the brake drum 500 communicates with the positioning hole 210. Subsequently, the connecting rod 320 brings the clamping rod 310 to move downward and is gradually inserted into the through-hole 510 of the brake drum 500. As the lower end of the clamping lever 310 contacts the wall of the through-hole 510 of the brake drum 500 and continues downward, the brake drum 500 is gradually moved by being pressed by the tapered end of the clamping lever 310 such that the center of the mounting surface is gradually aligned with the center of the positioning hole 210.

The driving gear 440 is connected to a rotation shaft of the driving motor 430, and a plurality of driven gears 450 are engaged with the driving gear 440 and are connected to one of the drill bits 420. This arrangement allows one motor to drive a plurality of drill bits 420, simplifying the construction of the apparatus.

Further, the clamping rod 310 is screw-coupled to the coupling rod 320 such that the length of the clamping rod 310 protruding from the coupling rod 320 is adjustable. The connecting rod 320 is further provided with a rubber block 321 at a side thereof adjacent to the positioning plate 200, so that the rubber block 321 is clamped between the brake drum 500 and the connecting rod 320 when the clamping rod 310 clamps the brake drum 500. When the brake drum clamping device is used, the length of the clamping rod 310 extending out of the connecting rod 320 is adjusted, so that when the clamping rod 310 clamps the brake drum 500, the rubber blocks 321 are contacted with the top of the brake drum 500 and are extruded and deformed. According to the arrangement, when the clamping rod 310 clamps the brake drum 500, the upper part of the brake drum 500 is also pressed, and meanwhile, the rubber block 321 has an anti-skidding effect, so that the brake drum 500 is prevented from shaking in the drilling process, and the drilling quality is ensured.

Further, the clamping rod 310 is fittingly provided with a lock nut 311. After the extended length of the clamping rod 310 is adjusted, the lock nut 311 is rotated so that the extended length of the clamping rod 310 is fixed. Variations in the length of the clamping bar 310 extension are avoided.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
