[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 grinding feed mechanism for a bearing grinder includes a workbench. A set of guide rails 1 are installed on the workbench. A motor 2 is arranged between the guide rails 1. The output end of the motor 2 is connected to a lead screw 4 through a coupling 3. A lead screw nut seat 5 is installed on the lead screw 4. The lead screw nut seat 5 is installed with a slide plate 6. Both sides of the slide plate 6 are connected to the guide rails 1. A support seat 7 is installed on the workbench. One end of the lead screw 4 is connected to the support seat 7 through a bearing seat 8. A spring 9 is arranged between the lead screw nut seat 5 and the support seat 8. The spring 9 is connected to the outside of the lead screw 4.

[0016] In this embodiment, the motor 2 is a servo motor. The servo motor is installed on the workbench. The servo motor has high precision and fast response. The output end of the servo motor is connected to the lead screw 4 through a diaphragm coupling. The guide rails 1 are cross roller guide rails. The fixed end of the cross roller guide rail is fixed on the workbench. The movable end of the cross roller guide rail is connected to the bottom of the slide plate 6. The grinding feed amount is precisely controlled by the servo motor.

[0017] In this embodiment, a guide seat 10 is arranged on the support seat 7. The lead screw 4 passes through the guide seat 10 and is connected to the bearing seat 8. One end of the spring 9 is sleeved on the guide seat 10. An annular groove 11 is machined on the end face of the lead screw nut seat 5. The other end of the spring 9 is stuck in the annular groove 11. By arranging a spring between the lead screw nut seat 5 and the guide seat 10, the internal gap between the lead screw nut seat 5 and the lead screw 4 can be eliminated, making the grinding more accurate.
