[0031] The specific working process of this utility model:

[0032] First, use the mechanical claw 15 to hoist the brake drum 2 to the top of the tooling, and put the brake drum 2 into the outer side of the cover plate 5. The mechanical claw 15 continues to descend until the bottom side of the brake drum 2 abuts against the oil receiving plate 9. At this time, the bottom side of the mechanical claw 15 abuts against the cover plate 5, and the mechanical claw 15 begins to shrink and separate from the brake drum 2. The brake drum 2 is pressed against the oil receiving plate 9 by gravity to overcome the elastic force of the spring 2 10, and continues to move downward until the brake drum 2 reaches the position of the clamping claw 1. At this time, the inner side of the installation surface of the brake drum 2 also abuts against the cover plate 5, so as to achieve the sealing of the inside of the brake drum 2;

[0033] The chuck 13 is started, and the claw 1 on the chuck 13 slides to abut against the inner side of the brake drum 2, thereby fixing the brake drum 2;

[0034] The top mounting surface and the side surface of the brake drum 2 are sprayed with paint by a paint spray nozzle, and the brake drum 2 is uniformly sprayed with paint by rotating the chuck 13. During the spraying, the paint flowing down from the brake drum 2 falls into the receiving groove 16, and the paint is collected by the receiving groove 16;

[0035] When the brake drum 2 is sprayed, the mechanical claw 15 is lowered to abut against the cover plate 5, and continues to descend to extend into the inner side of the mounting surface of the brake drum 2, and then the chuck 13 is started to separate the claw 1 from the brake drum 2, and finally the brake drum 2 is lifted by the mechanical claw 15 to complete the painting operation of the brake drum 2.

[0036] A spring 6 is sleeved on the outer side of the core shaft 7, and the spring 6 abuts against the cover plate 5. The top edge of the cover plate 5 abuts against the inner side of the mounting surface of the brake drum 2. A mechanical claw 15 is arranged above the brake drum 2. The outer side of the mechanical claw 15 is detachably connected to the inner side of the brake drum 2, and the bottom side of the mechanical claw 15 abuts against the top edge of the cover plate 5 detachably. The mechanical claw 15 can be used to complete the hoisting and positioning of the brake drum 2 without manual operation, and the installation and fixing of the brake drum 2 is convenient and quick.

[0037] The outer side of the core shaft 7 is detachably sleeved with a plurality of adjusting washers 8. If the adjusting washers 8 are arranged between the fixing plate 12 and the spring 1 6, the elastic force of the spring 1 6 on the cover plate 5 can be adjusted by adjusting the number of washers 8. The outer side of the guide column 11 is sleeved with a spring 2 10. A limiting nut 14 is arranged on the top side of the guide column 11. The elastic force of the spring 2 10 connecting the oil plate 9 can be adjusted by adjusting the limiting nut 14. By adjusting the adjusting washers 8 and the limiting nuts 14, the sealing effect of the cover plate 5 and the oil receiving plate 9 on the brake drum 2 can be better, thereby making the painting effect of the brake drum 2 better.

[0038] Note: A T-shaped block is provided on the chuck 13, and the clamping jaw 1 is driven to move on the chuck 13 by the T-shaped block. The chuck 13 and the clamping jaw 1 are both prior arts and will not be described in detail here.
