The side blocks 14 have slots 17. Grinding wheels 18 are rotatably arranged in the slots 17. Top plates 19 are respectively arranged on the two side blocks 14. Placement grooves 20 are opened on the top plates 19. Rotating shafts 21 are rotatably arranged on the placement grooves 20. Multiple fan blades 22 arranged in a circular shaft array are arranged on the rotating shafts 21. Fixing blocks 23 are arranged on the placement plate 1. Cross blocks 24 are arranged on the fixing blocks 23. The two top plates 19 are joined together in an inverted V shape. Multiple drop grooves 13 arranged in a linear array are opened on the placement plate 1.

[0025] Specifically, in use, the bearing roller is placed on the cross block 24 on the fixing block 23 to fix the bearing roller on the cross block 24. Then, the motor is started to drive the two grinding wheels 18 in the groove 17 on the side block 14 to rotate and grind the bearing roller. At the same time, the rotating shaft 21 on the top plate 19 is started and drives multiple fan blades 22 to rotate, blowing away the debris attached to the bearing roller and blowing it down onto the placement plate 1. The debris then falls into the drop groove 13 on the placement plate 1 for collection.

[0026] In the above scheme, the grinding wheel 18 is fixed by the side block 14 on the placement plate 1, the bearing roller is fixed by the fixing block 23 and the cross block 24 on the placement plate 1, the rotating shaft 21 is installed by the top plate 19 on the side block 14, and the multiple fan blades 22 blow away the debris generated by the bearing roller during grinding and blow it into the multiple drop grooves 13 opened on the placement plate 1 for collection.

[0027] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, a box 10 is provided at the bottom of the placement plate 1, and a collection box 100 is slidably disposed inside the box 10. The collection box 100 is connected to the drop groove 13.

[0028] Specifically, after the debris is blown away by the fan blades 22, it falls into the drop groove 13, then enters the box 10 through the drop groove 13, and then enters the collection box 100 inside the box 10 to collect the debris. When taking it out, the collection box 100 is slid out from the box 10.

[0029] As a further embodiment provided by this utility model, according to Figure 2 As shown, a moving groove 26 is provided on the cross block 24, and a plurality of first elastic elements 27 arranged in a linear array are provided in the moving groove 26.

[0030] Furthermore, a sliding block 28 is slidably disposed within the moving groove 26, and the sliding block 28 is pushed and fixed within the moving groove 26 by the first elastic member 27.

[0031] Specifically, the bearing roller is placed on the sliding block 28 on the cross block 24, and the bearing roller is locked on the cross block 24. Then the first elastic element 27 ensures that it will not wobble during grinding.

[0032] As a further embodiment provided by this utility model, according to Figure 2 As shown, a sleeve 29 is provided on the sliding block 28, and a sliding cavity 30 is provided on the sleeve 29. A second elastic element 31 is provided at the bottom of the sliding cavity 30.

[0033] Furthermore, a sliding push rod 32 is slidably disposed inside the sliding cavity 30, and an anti-slip pad is disposed on the sliding push rod 32.

[0034] Specifically, after the bearing roller is placed on the cross block 24, the inner wall of the bearing roller will contact the sliding push rod 32. At the same time, the anti-slip pad on the sliding push rod 32 will prevent the bearing roller from slipping on the sliding push rod 32, and the second elastic element 31 will further fix the bearing roller.

[0035] As a further embodiment provided by this utility model, according to Figure 2 As shown, a slider 15 is provided at the bottom of the side block 14. The slider 15 is slidably disposed in the groove 12 opened on the placement plate 1. Connecting rods 16 are provided on the two side blocks 14.

[0036] Furthermore, a limit rod 25 is provided at the center of the cross block 24.

[0037] Specifically, pulling the connecting rod 16 causes the two side blocks 14 to slide within the slide groove 12 via the slider 15, thereby removing the bearing from the limiting rod 25 on the cross block 24.

[0038] Working principle: During use, the support column 11 supports the placement plate 1, and the bearing roller is placed on the sliding block 28 on the cross block 24, thus securing the bearing roller on the cross block 24. The first elastic element 27 ensures that the bearing roller will not wobble during grinding. At the same time, the inner wall of the bearing roller will contact the sliding push rod 32, and the anti-slip pad on the sliding push rod 32 will prevent the bearing roller from slipping on the sliding push rod 32. Meanwhile, the second elastic element 31 further fixes the bearing roller. Then, the motor is started to drive the side block 14 into the groove 17. The two grinding wheels 18 rotate to grind the bearing rollers. At the same time, the rotating shaft 21 on the top plate 19 starts and drives multiple fan blades 22 to rotate, blowing away the debris attached to the bearing rollers and onto the placement plate 1. The debris falls into the drop groove 13 on the placement plate 1. After being blown away by the fan blades 22, the debris falls into the drop groove 13 and then enters the box 10 through the drop groove 13. It then enters the collection box 100 inside the box 10 to collect the debris. When taking it out, the collection box 100 is slid out of the box 10.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
