DETAILED DESCRIPTION OF THE INVENTION

[0032] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] As Figures 1 to 6 shown, a diamond grinding wheel device for grinding the inner diameter of a bearing sleeve according to an embodiment of the present invention includes a workbench 1, a fixing frame 2 is arranged above the workbench 1, two placing plates 201 are arranged inside the fixing frame 2, a bearing sleeve body 3 is placed above the two placing plates 201, two clamping fixtures 4 are arranged above the fixing frame 2, and the two clamping fixtures 4 are used to clamp the bearing sleeve body 3 to be ground. A toothed disc 101 is rotatably arranged above the workbench 1, and the toothed disc 101 is connected to the side wall of the clamping fixture 4 through a bracket. The toothed disc 101 drives the clamping fixture 4 and the bearing sleeve body 3 to rotate through the bracket, and a diamond grinding wheel main body 5 is arranged above the workbench 1;

[0034] During operation, the bearing sleeve body 3 to be ground is placed above the placing plate 201, and the two clamping fixtures 4 are controlled to move through an external controller, so that the two clamping fixtures 4 fix the outer peripheral surface of the bearing sleeve body 3. Then, the diamond grinding wheel main body 5 is controlled to move towards the inner diameter side of the bearing sleeve body 3 through the external controller, so that the grinding part of the diamond grinding wheel main body 5 contacts the inner diameter of the bearing sleeve body 3. Then, the toothed disc 101 is controlled to rotate through the controller, so that the toothed disc 101 drives the clamping fixture 4 and the bearing sleeve body 3 to rotate. Then, the diamond grinding wheel main body 5 can grind the inner diameter of the bearing sleeve body 3. The two clamping fixtures 4 can fix bearing sleeves with different diameters, and the operation is relatively convenient.

[0035] Two reciprocating cylinders 6 are installed on the inner wall of the toothed disc 101, and the telescopic ends of the two reciprocating cylinders 6 are respectively connected to the side wall of the clamping fixture 4. The clamping fixture 4 is made of rubber, and a spring is sleeved on the outer surface of the telescopic end of the reciprocating cylinder 6. The side wall of the fixing frame 2 is connected to the side wall of the toothed disc 101 through a bracket; during operation, when the bearing sleeve body 3 is placed above the placing plate 201, by controlling the rotation of the two reciprocating cylinders 6 on both sides, the telescopic ends of the reciprocating cylinders 6 will drive the clamping fixture 4 to move, so that the clamping fixture 4 moves towards the outside of the bearing sleeve body 3. Then, the two clamping fixtures 4 on both sides will fix the bearing sleeve body 3. Subsequently, by controlling the rotation of the above-mentioned diamond grinding wheel main body 5, the inner diameter of the bearing sleeve can be ground.

[0036] As Figures 2 to 6As shown, a central gear 7 is installed on the inner wall of the fixing bracket 2. The telescopic end of the reciprocating cylinder 6 is installed with an L-shaped bracket 8. A first toothed plate 9 is installed at the end of the L-shaped bracket 8 away from the telescopic end of the reciprocating cylinder 6. A second toothed plate 10 is installed below the placing plate 201. The central gear 7 is meshed and connected with the first toothed plate 9 and the second toothed plate 10 respectively. The clamp 4 is in the shape of an annular rubber sleeve. During operation, when the bearing sleeve body 3 is placed above the placing plate 201, at this time, the clamps 4 on both sides have not yet contacted the outer wall of the bearing sleeve body 3. Then, when the telescopic end of the reciprocating cylinder 6 drives the clamp 4 to move towards the side close to the bearing sleeve body 3, the telescopic end of the reciprocating cylinder 6 will simultaneously drive the L-shaped bracket 8 to move. The L-shaped bracket 8 drives the first toothed plate 9 to move. The first toothed plate 9 drives the second toothed plate 10 to move through the engagement of the central gear 7. The second toothed plate 10 drives the placing plate 201 to move. When the clamp 4 contacts the outer wall of the bearing sleeve body 3, at this time, the placing plate 201 gradually moves away from the bottom of the bearing sleeve body 3. Since the clamp 4 is in the shape of an annular rubber sleeve, when the clamp 4 gradually adheres to the outer wall of the bearing sleeve body 3, the placing plate 201 will completely move away from the bottom of the bearing sleeve body 3. In this way, it is convenient for the subsequent diamond grinding wheel body 5 to grind the inner diameter of the bearing sleeve, that is, to avoid the problem that the placing plate 201 at the bottom of the bearing sleeve body 3 affects the grinding of the diamond grinding wheel body 5.

[0037] As Figures 3 to 8 shown, a limiting frame adapted to the first toothed plate 9 and the second toothed plate 10 is arranged inside the fixing bracket 2. A driven gear 11 is rotatably arranged above the workbench 1. The driven gear 11 is connected to the output end of the motor through a vertical rod. The driven gear 11 is meshed and connected with the toothed disc 101. During operation, the limiting frame is provided to facilitate the mutual movement of the first toothed plate 9 and the second toothed plate 10. After the bearing sleeve body 3 is fixed, the motor is controlled to drive the driven gear 11 to rotate. The driven gear 11 drives the toothed disc 101 to rotate. The toothed disc 101 can drive the fixed bearing sleeve body 3 to rotate. Then, the diamond grinding wheel body 5 can grind the inner diameter of the bearing sleeve.

[0038] Above the workbench 1, a support frame 12 is installed. At the end of the support frame 12 away from the workbench 1, a connecting bracket 13 is provided. At the end of the connecting bracket 13 away from the support frame 12, a first electric push rod 131 is installed. The telescopic end of the first electric push rod 131 is connected with a second electric push rod 132, and the diamond grinding wheel body 5 is connected with the telescopic end of the second electric push rod 132. During operation, after the bearing sleeve body 3 is fixed, first, the telescopic end of the first electric push rod 131 is controlled to drive the second electric push rod 132 to move. The second electric push rod 132 drives the diamond grinding wheel body 5 to move, so that the diamond grinding wheel body 5 moves towards the inner diameter side of the bearing sleeve. Subsequently, the telescopic end of the second electric push rod 132 is controlled to drive the diamond grinding wheel body 5 to move, so that the diamond grinding wheel body 5 moves to the inner wall of the bearing sleeve, that is, the outer surface of the diamond grinding wheel body 5 contacts the inner wall of the bearing sleeve.

[0039] The telescopic end of the second electric push rod 132 is connected with a micro motor 14. The output end of the micro motor 14 is connected with the side wall of the diamond grinding wheel body 5. An adjusting unit is provided at the end of the support frame 12 away from the workbench 1. The adjusting unit is used to drive the connecting bracket 13 to move. During operation, after the diamond grinding wheel body 5 is adjusted and the bearing sleeve body 3 is fixed, the bearing sleeve body 3 is driven to rotate by the gear disk 101, and the micro motor drives the diamond grinding wheel body 5 to rotate. In this way, grinding of the inner diameter of the bearing sleeve can be achieved. Under the action of the adjusting unit, the connecting bracket 13 can be driven to move, so as to drive the diamond grinding wheel body 5 to move along the vertical direction of the inner diameter of the bearing sleeve, which is convenient for further grinding of the diamond grinding wheel body 5.

[0040] Such as Figures 4 to 8As shown in the figure, the adjusting unit includes a cylinder 15, which is fixedly installed at the end of the support frame 12. A sliding column 133 is installed at the top of the connecting bracket 13. Two groups of limit columns 16 are installed on the outer peripheral surface of the sliding column 133. The two groups of limit columns 16 are slidably arranged on the inner wall of the cylinder 15. An L-shaped top column 17 is installed on the side wall of the connecting bracket 13. The bottom end of the L-shaped top column 17 is circular arc-shaped. Multiple groups of mounting brackets 18 are installed on the upper end surface of the gear disk 101. The end of each group of mounting brackets 18 is installed with a matching plate 19. The end of the matching plate 19 is installed with an arc-shaped top block 20. When the arc-shaped top block 20 rotates following the gear disk 101, the arc-shaped top block 20 will contact the bottom end of the L-shaped top column 17; during operation, when the gear disk 101 drives the completed bearing sleeve body 3 to rotate, the gear disk 101 will simultaneously drive the mounting bracket 18 to rotate, the mounting bracket 18 will drive the matching plate 19 to rotate, and the matching plate 19 will drive the arc-shaped top block 20 on the upper end surface to rotate. During the rotation of the arc-shaped top block 20, it will contact the bottom end of the L-shaped top column 17. Therefore, when the bottom end of the L-shaped top column 17 gradually contacts the bottom surface and the arc-shaped high point of the arc-shaped top block 20, the arc-shaped top block 20 will apply a certain pressure to the bottom end of the L-shaped top column 17. Thus, the L-shaped top column 17 will drive the connecting bracket 13 to move upward, and the connecting bracket 13 will drive the first electric push rod 131, the second electric push rod 132, and the diamond grinding wheel body 5 to move along the inner diameter direction of the bearing sleeve. That is, the diamond grinding wheel body 5 will perform multi-directional grinding on the inner diameter of the bearing sleeve, improving the grinding effect of the inner diameter of the bearing sleeve.

[0041] A telescopic elastic rod 21 is installed at the top end of the limit column 16. A spring is sleeved on the outer surface of the telescopic elastic rod 21. The top end of the telescopic elastic rod 21 is connected to the top wall of the cylinder 15. A limit groove adapted to the limit column 16 is provided on the inner wall of the cylinder 15; during operation, when the arc-shaped surface of the arc-shaped top block 20 presses against the bottom end of the L-shaped top column 17, that is, when the connecting bracket 13 moves upward, the connecting bracket 13 will drive the sliding column 133 to move upward, the sliding column 133 will drive the two side limit columns 16 to move upward, and the limit columns 16 will move upward on the inner wall of the cylinder 15 and squeeze the telescopic elastic rod 21. When the arc-shaped top block 20 separates from the L-shaped top column 17, under the elastic recovery of the telescopic elastic rod 21, the connecting bracket 13 will return to the initial position. Due to the design of multiple groups of mounting brackets 18 and arc-shaped top blocks 2, the L-shaped top column 17 will be intermittently pressured, that is, the connecting bracket 13 will move intermittently. Thus, the diamond grinding wheel body 5 will move intermittently on the inner wall of the bearing sleeve, improving the grinding efficiency.

[0042] As Figure 9 shown, a diamond grinding wheel grinding method for grinding the inner diameter of a bearing sleeve. This method uses the above-mentioned diamond grinding wheel equipment for grinding the inner diameter of a bearing sleeve, including the following steps:

[0043] S1. Place the bearing sleeve body 3 to be ground above the placement plate 201, and control the movement of the two sets of jigs 4 through an external controller, so that the two sets of jigs 4 fix the outer peripheral surface of the bearing sleeve body 3;

[0044] S2. Then, control the diamond grinding wheel body 5 to move towards the inner diameter side of the bearing sleeve body 3 through an external controller, so that the grinding part of the diamond grinding wheel body 5 contacts the inner diameter of the bearing sleeve body 3;

[0045] S3. Control the rotation of the gear disk 101 through the controller, so that the gear disk 101 drives the jig 4 and the bearing sleeve body 3 to rotate. Then, the diamond grinding wheel body 5 can grind the inner diameter of the bearing sleeve body 3.

[0046] In the steps S1 - S3, the material of the jig 4 is a ring-shaped rubber sleeve.

[0047] During operation, place the bearing sleeve body 3 to be ground above the placement plate 201, and control the movement of the two sets of jigs 4 through an external controller, so that the two sets of jigs are fixed to the outer peripheral surface of the bearing sleeve body 3. Then, control the diamond grinding wheel body 5 to move towards the inner diameter side of the bearing sleeve body 3 through an external controller, so that the grinding part of the diamond grinding wheel body 5 contacts the inner diameter of the bearing sleeve body 3. Then, control the rotation of the gear disk 101 through the controller, so that the gear disk 101 drives the jig 4 and the bearing sleeve body 3 to rotate. Then, the diamond grinding wheel body 5 can grind the inner diameter of the bearing sleeve body 3; when the bearing sleeve body 3 is placed above the placement plate 201, by controlling the rotation of the reciprocating cylinders 6 on both sides, the telescopic ends of the reciprocating cylinders 6 will drive the jigs 4 to move, so that the jigs 4 move towards the outside of the bearing sleeve body 3. Then, the two sets of jigs 4 will fix the bearing sleeve body 3, and then control the rotation of the above-mentioned diamond grinding wheel body 5 to grind the inner diameter of the bearing sleeve.

[0048] When the bearing sleeve body 3 is placed above the placement plate 201, at this time, the two sets of jigs 4 have not yet contacted the outer side wall of the bearing sleeve body 3. Then, when the telescopic ends of the reciprocating cylinders 6 drive the jigs 4 to move towards the bearing sleeve body 3, the telescopic ends of the reciprocating cylinders 6 will simultaneously drive the L-shaped brackets 8 to move, and the L-shaped brackets 8 drive the first toothed plate 9 to move. The first toothed plate 9 will drive the second toothed plate 10 to move through the meshing of the central gear 7, and the second toothed plate 10 will drive the placement plate 201 to move. When the jig 4 contacts the outer wall of the bearing sleeve body 3, at this time, the placement plate 201 gradually moves away from the bottom of the bearing sleeve body 3. Since the shape of the jig 4 is a ring-shaped rubber sleeve, when the jig 4 gradually adheres to the outer wall of the bearing sleeve body 3, the placement plate 201 will completely move away from the bottom of the bearing sleeve body 3. In this way, it is convenient for the subsequent diamond grinding wheel body 5 to grind the inner diameter of the bearing sleeve, that is, to avoid the problem that the placement plate 201 at the bottom of the bearing sleeve body 3 affects the grinding of the diamond grinding wheel body 5;

[0049] After the bearing sleeve body 3 is fixed, first control the telescopic end of the first electric push rod 131 to drive the second electric push rod 132 to move. The second electric push rod 132 drives the diamond grinding wheel body 5 to move, so that the diamond grinding wheel body 5 moves towards the inner diameter side of the bearing sleeve. Subsequently, control the telescopic end of the second electric push rod 132 to drive the diamond grinding wheel body 5 to move, so that the diamond grinding wheel body 5 moves to the inner wall of the bearing sleeve, that is, the outer surface of the diamond grinding wheel body 5 contacts the inner wall of the bearing sleeve;

[0050] When driving the fixed bearing sleeve body 3 to rotate through the gear disk 101, the gear disk 101 will drive the mounting bracket 18 to rotate at the same time. The mounting bracket 18 will drive the mating plate 19 to rotate, and the mating plate 19 will drive the arc-shaped top block 20 on the upper end surface to rotate. During the rotation of the arc-shaped top block 20, it will contact the bottom end of the L-shaped top post 17. Therefore, when the bottom end of the L-shaped top post 17 gradually contacts the bottom surface and the arc height of the arc-shaped top block 20, the arc-shaped top block 20 will give a certain pressure to the bottom end of the L-shaped top post 17. Thus, the L-shaped top post 17 will drive the connecting bracket 13 to move upward, and the connecting bracket 13 will drive the first electric push rod 131, the second electric push rod 132, and the diamond grinding wheel body 5 to move along the inner diameter direction of the bearing sleeve, that is, the diamond grinding wheel body 5 will perform multi-directional grinding on the inner diameter of the bearing sleeve, improving the grinding effect of the inner diameter of the bearing sleeve;

[0051] When the arc surface of the arc-shaped top block 20 presses against the bottom end of the L-shaped top post 17, that is, when the connecting bracket 13 moves upward, the connecting bracket 13 will drive the sliding column 133 to move upward. The sliding column 133 drives the limiting columns 16 on both sides to move upward. The limiting columns 16 will move upward on the inner wall of the cylinder 15 and squeeze the telescopic elastic rod 21. When the arc-shaped top block 20 separates from the L-shaped top post 17, under the elastic recovery of the telescopic elastic rod 21, the connecting bracket 13 will return to the initial position. Due to the design of multiple groups of mounting brackets 18 and arc-shaped top blocks 20, the L-shaped top post 17 will be intermittently pressured, that is, the connecting bracket 13 will move intermittently. Thus, the diamond grinding wheel body 5 will intermittently move on the inner wall of the bearing sleeve, improving the grinding efficiency.
