Specific embodiments

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.

[0015] As Figure 1 and Figure 2 shown, a chamfer trimming device for a bearing race includes a base 1, on which a stop block 2 and a pressing block 3 are arranged. The stop block 2 is fixed on the base 1, and the pressing block 3 is slidably connected to the base 1. In this embodiment, a guide rail 4 is installed on the base 1, a slider is arranged on the guide rail 4, and the pressing block 3 is installed on the slider. The stop block 2 and the pressing block 3 are machined with "V"-shaped openings. An adjusting screw 5 is arranged on the side surface of the base 1, and the adjusting screw 5 is screwed on the fixing block 6 on the side surface of the base. When the adjusting screw 5 is tightened, the pressing block 3 is pressed and fixed to clamp the bearing race with the "V"-shaped opening.

[0016] One side of the base 1 is connected with a support frame 7. A sliding table 8 is installed on the surface of the support frame 7. A sliding block is connected to the sliding table 8. The surface of the sliding block is connected with a bearing seat 10 through a connecting block 9. A rotating shaft 11 is arranged in the bearing seat 10. A bearing is arranged in the bearing seat 10, and the rotating shaft 11 is matched with the bearing. A motor bracket 12 is installed on the bearing seat 10, and a motor 13 is installed on the motor bracket 12. The output end of the motor 13 is connected to the upper end of the rotating shaft 11 through a coupling. The lower end of the rotating shaft 11 is connected with a milling cutter 14. The milling cutter 14 is sleeved in the mounting hole at the bottom of the rotating shaft 11 and locked by a set screw. A screw rod 15 is connected to the support frame 7. An adjusting block 16 is connected to the screw rod 15. The adjusting block 16 is screwed on the screw rod 15. A supporting surface 17 is arranged on the adjusting block 16.
