The light beam of the photoelectric sensor 26 is irradiated above the chain of the chain conveyor 21 through the hole on the frame 24. When the bearing 9 is detected to reach the position irradiated by the photoelectric sensor 26, the external control system (not shown in the figure) controls the chain conveyor 21 to stop, so that the bearing 9 is parked at an accurate grasping position to prevent the bearing 9 from falling from the chain conveyor 21, and facilitates the Z-axis clamping assembly 74 to clamp the bearing 9, thereby improving the accuracy and efficiency of clamping and improving the efficiency of grinding.

[0035] like Fig.12 As shown, the discharge assembly 3 includes a discharge box 31, in which a plurality of vertical material columns 32 are evenly arranged, and the material columns 32 are used to store the polished bearings; the polished bearings 9 are mounted on the material columns 32, and a right-angle positioning angle 33 is also arranged on the support platform 1, and the inner wall of the right-angle positioning angle 33 is against the bottom corner of the pre-discharge box body, and at least two right-angle positioning angles 33 are arranged for positioning the discharge box 31; the setting of the discharge assembly 3 reduces the manual packing steps, reduces the labor intensity, and improves the work efficiency.

The photoelectric sensor 26 detects the bearings 9 and stops the chain conveyor 21. The bearings 9 are clamped by the Z-axis clamping component 74, so that the outer wall surfaces of the clamping blocks 743 are respectively pressed against the outer ring surfaces 92 of the bearings 9, and the protruding parts of the fixing parts 742 are pressed against the end surfaces 91 of the bearings 9, and the bearings 9 are clamped so that the bearings 9 are not offset or skewed when clamped, and are firmly clamped. The slide assembly 7 moves to transfer the bearings 9 to the top of the grinding wheel component 43, and the grinding component 4 rises between the rotating clamping jaw blocks 56. The Z-axis clamping component 74 moves downward to fit the bearings 9, and at the same time, the fixing parts 742 protrude to press the bearings 9 downward, so that the bearings 9 are completely fitted vertically on the grinding wheel component 43, and the lower end surface of the bearings 9 is completely pressed against On the upper surface of the large grinding wheel in the grinding wheel part 43, the Z-axis clamping assembly 74 moves upward, and the flip clamping assembly 5 is adjusted to make the rotating claw block 56 clamp the bearing 9, and the second rotating motor 42 in the grinding assembly 4 rotates, driving the grinding wheel part 43 to rotate, and the end face 91 and the inner ring surface 93 of the bearing 9 are ground; then, the slide assembly 7 is adjusted to make the pneumatic grinding pen 76 in the Z-axis grinding assembly 75 grind the fillet 94 of the bearing 9; the flip clamping assembly 5 is adjusted to flip so that the bearing is flipped 180 degrees, and the grinding assembly 4 rises to grind the lower end face 91 and the inner ring surface 93 of the bearing 9, and the pneumatic grinding pen 76 in the Z-axis grinding assembly 75 grinds the fillet 94 connecting the upper end face 91 and the inner ring surface 93 of the bearing 9, and the grinding is completed, the flip clamping assembly 5 releases the bearing, and the Z-axis clamping assembly 74 clamps the bearing to the material column 32 of the discharge box 31 in the discharge assembly 3.
