[0020] Multiple sets of connecting rods 23 are fitted with an inner support assembly 3 around the outer ring of the threaded upright 1. The inner support assembly 3 includes a fixed sleeve 31, with a fixed plate 7 on one side above the fixed sleeve 31. The mounting end of the fixed sleeve 31 is installed correspondingly to one side of the fixed plate 7, and the fixed sleeve 31 is fixedly connected to the fixed plate 7. The mounting end of the fixed plate 7 is installed correspondingly to one side of the connecting plate 22, and the fixed plate 7 is fixedly connected to the connecting plate 22. The fixed plate 7 can be used to fix the fixed sleeve 31 through the connecting plate 22. A shaft hole is opened at the middle position on both the fixed sleeve 31 and the fixed plate 7. The outer ring of the threaded upright 1 fits against the inner wall of the shaft hole. The threaded upright 1 is rotatably connected to the fixed sleeve 31 through the shaft hole. The outer ring has multiple sets of limiting slots 10, and the connecting rod 23 is installed correspondingly to the limiting slots 10. The limiting slots 10 can limit the movement of the connecting rod 23. An adjusting sleeve 32 is provided below the fixed sleeve 31. A threaded hole 6 is provided on the adjusting sleeve 32 at the middle position. The outer ring of the threaded rod 1 is installed correspondingly to the inner ring of the threaded hole 6.

The outer rings at both ends of the fixed sleeve 31 and the outer ring of the adjusting sleeve 32 are circumferentially arranged. The column is provided with multiple sets of adjusting rods 33. The outer rings of both the upper and lower ends of the fixed sleeve 31 and the outer ring of the adjusting sleeve 32 are each provided with multiple sets of mounting ears 8.

[0021] In this embodiment, the operator first places the brake drum to be processed stably, then lifts the device using the lifting ring 4, and places the device in the inner cavity of the brake drum. The operator then rotates the threaded rod 1, at which point the positioning component 2 positions and stabilizes the threaded rod 1. The rotation of the threaded rod 1, through its threaded connection with the threaded hole 6, drives the adjusting sleeve 32 to perform axial guiding adjustment along the threaded rod 1. The movement of the adjusting sleeve 32 drives the connecting ear 9 to rotate through the mounting ear 8. The rotation of the connecting ear 9 pushes the inner support plate 34, thereby causing multiple sets of inner support plates 34 to be supported in the inner cavity of the brake drum. This causes the inner support plates 34 to drive the rubber pad 35 to fit against the inner wall of the brake drum. Then, the threaded rod 1 is rotated again, so that the inner support plates 34 and the rubber pad 35 cooperate to stabilize the inner cavity of the brake drum, thus allowing the brake drum to be processed.
