It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0026] As Figure 1 - Figure 2 shown, a positioning and fixing device for carbon brush processing proposed by the present utility model includes a mounting housing. The mounting housing includes a bottom plate 1. A mounting bracket 10 is provided on the bottom plate 1. A punching device 2 is provided downward at the top of the mounting bracket 10. A mounting groove 11 is formed on the bottom plate 1. A driving component 3 is provided in the mounting groove 11. A positioning back plate 4 is provided on the driving component 3. An abutting plate 5 is movably provided on the positioning back plate 4. A fixing component 6 is provided on the side of the positioning back plate 4 away from the abutting plate 5.

[0027] As Figure 3 shown, a pair of first sliding grooves 12 are symmetrically formed on the bottom plate 1. The two first sliding grooves 12 are respectively located on both sides of the mounting groove 11. A first scale mark 13 is provided on the right side of the bottom plate 1; the zero scale lines of the first scale mark 13 and the second scale mark 45 are both aligned with the drill bit of the punching device 2.

[0028] As Figure 4 shown, the driving component 3 includes a lead screw 31 movably provided in the mounting groove 11. One end of the lead screw 31 is provided at the transmission end of a motor 30. The motor 30 is provided on one side of the bottom plate 1.

[0029] As Figure 6As shown in the figure, a driving member 40 is provided at the bottom of the positioning back plate 4. The driving member 40 is threadedly arranged on the lead screw 31. Symmetrically arranged on both sides of the driving member 40 are sliding blocks 41. The sliding blocks 41 are arranged in the first sliding groove 12. A second scale mark 45 is provided on the positioning back plate 4. Below the second scale mark 45 is an activity groove 43. A sliding rail 44 is arranged in the activity groove 43. The abutting plate 5 is arranged on the activity groove 43. On one side of the positioning back plate 4 close to the first scale mark 13 is an arrow 46. The arrow 46 is arranged in contact with the first scale mark 13. On the side of the positioning back plate 4 away from the activity groove 43 is a mounting plate 42. A fixing assembly 6 is arranged on the mounting plate 42.

[0030] As Figure 7 shown, a second sliding groove 50 is provided on the abutting plate 5. The sliding rail 44 is arranged in the second sliding groove 50. At the top of the abutting plate 5 is a locking bolt 51.

[0031] As an optimized solution of the present utility model, by providing the sliding blocks 41 and the sliding rails 44, the positioning back plate 4 and the abutting plate 5 can move more smoothly during movement, avoiding jamming.

[0032] As Figure 8 shown, the fixing assembly 6 includes a telescopic cylinder 60 arranged on the mounting plate 42. After the telescopic rod of the telescopic cylinder 60 passes through the mounting plate 42, a connecting plate 61 is arranged at its top. A rubber pad 62 is arranged on the connecting plate 61.

[0033] As an optimized solution of the present utility model, by providing the rubber pad 62 on the connecting plate 61, the carbon brush can be protected, avoiding indentation on the carbon brush during clamping.
