Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, an end face grinding device for automotive bearing races includes a processing table 1, a lifting mechanism 2, a rotary motor 6, a mounting plate 7, bearing races 8, and a support mechanism 9. The lifting mechanism 2 and the rotary motor 6 are fixedly mounted on the upper part of the processing table 1. The lifting mechanism 2 is driven by a lifting plate 3, and a grinding motor 4 is mounted on the lifting plate 3. The grinding motor 4 is driven by a grinding wheel 5.

[0020] A rotary motor 6 drives a mounting plate 7, on which bearing rings 8 are fixedly mounted. The rotary motor 6 rotates the mounting plate 7, causing the bearing rings 8 at different positions on the mounting plate 7 to rotate below the grinding wheel 5. The lifting mechanism 2 drives the lifting plate 3 to descend, bringing the grinding wheel 5 into contact with the upper surface of the bearing rings 8 below. The grinding motor 4 is then activated to rotate the grinding wheel 5, thus grinding its upper surface. When the bearing rings 8 are fixed to the mounting plate 7, their upper surfaces protrude beyond the top of the mounting plate 7.

[0021] The support mechanism 9 is installed on the upper part of the processing table 1 and located below the grinding wheel 5. The support mechanism 9 supports and assists in fixing the bearing ring 8 that reaches under the grinding wheel 5, ensuring the stability of the bearing ring 8 during the grinding process, so that the end face of the bearing ring 8 will not shift during the grinding process, and the grinding will meet the corresponding processing requirements.

[0022] Furthermore, the lifting mechanism 2 includes a mounting base 22, on which a lead screw motor 23 is mounted. The lead screw motor 23 drives and connects to a lead screw 24. A lead screw slider 25 is mounted on the lead screw 24. The lifting plate 3 is fixedly mounted on the lead screw slider 25.

[0023] Furthermore, the mounting plate 7 includes a support plate 10, an inner ring 11, and an outer ring 12. The inner ring 11 is fixedly mounted on the upper part of the support plate 10, and the outer ring 12 is located outside the inner ring 11. The outer ring 12 and the inner ring 11 are concentrically arranged, and a number of fixing rods 13 are connected between the inner ring 11 and the outer ring 12. The inner ring 11 and the outer ring 12 are relatively fixed by the fixing rods 13.

[0024] Furthermore, the bearing ring 8 is mounted on the mounting plate 7 using a fixing fixture located between the inner ring 11 and the outer ring 12, and between two adjacent fixing rods 13. When the bearing ring 8 is mounted on the fixing fixture, ensure that the upper end face of the bearing ring 8 extends beyond the upper end faces of the inner ring 11 and the outer ring 12.

[0025] The fixture includes a positioning block 14, a clamping block 15, and a moving mechanism. The positioning block 14 is fixed to the inner side of the outer ring 12. The moving mechanism is mounted on the upper part of the support plate 10. The moving mechanism drives the clamping block 15, which moves closer to the positioning block 14. The clamping block 15 and the positioning block 14 then press against the bearing ring 8 for fixation. When the clamping block 15 moves away from the positioning block 14, the fixation of the bearing ring 8 is released.

[0026] Furthermore, the moving mechanism includes a lead screw motor 16, which drives a lead screw 18. A lead screw slider 17 is mounted on the lead screw 18, and a connecting rod 19 is connected to the lead screw slider 17. The end of the connecting rod 19 away from the lead screw slider 17 passes through the inner ring 11 and connects to the clamping block 15. Rubber sheets are installed on the opposite sides of the positioning block 14 and the clamping block 15. The rubber sheets can increase the friction with the bearing ring 8, making the clamping stability better, and at the same time, they can prevent damage to the bearing ring 8, thus protecting the bearing ring 8.

[0027] The support mechanism 9 includes a cylinder 29 and a support plate 26. The piston rod of the cylinder 29 is connected to a lifting block 28, and several support rods 27 are connected between the lifting block 28 and the support plate 26. The diameter of the support plate 26 is smaller than the distance between the inner ring 11 and the outer ring 12 to ensure that the support plate 26 can rise between the inner ring 11 and the outer ring 12 to support the bearing ring 8.

[0028] A guide sleeve 20 is connected to the lifting block 28, and a guide rod 21 is fixedly connected to the processing table 1. The guide sleeve 20 and the guide rod 21 are vertically arranged, and part of the guide rod 21 is inserted into the guide sleeve 20. The guide sleeve 20 and the guide rod 21 cooperate to guide the lifting and lowering of the support plate 26, ensuring that the support plate 26 moves vertically and keeps the support plate 26 in a horizontal state to effectively support the bearing ring 8.

[0029] The support mechanism 9 also includes a mounting sleeve 30 and a second cylinder 34. The mounting sleeve 30 is mounted on the upper part of the support plate 26. A clamping block 32 is provided on the side wall of the mounting sleeve 30. The clamping block 32 is arranged radially along the mounting sleeve 30. A guide slope 33 is provided at the inner end of the clamping block 32. The guide slope 33 is inclined inward and upward. The second cylinder 34 drives and connects to a clamping head 35. The clamping head 35 is conical. The outer circumferential surface of the clamping head 35 can fit against the guide slope 33. A mounting groove 36 is also provided in the mounting sleeve 30. The mounting groove 36 is located above the moving groove 31 and is connected to the moving groove 31. A moving block 37 is connected to the upper part of the clamping block 32. A spring 38 is connected to the side of the moving block 37. The other end of the spring 38 is connected to the outer wall of the mounting groove 36. The mounting sleeve 30 rises with the support plate 26, so that the clamping block 32 abuts against the inner wall of the bearing ring 8, thereby playing an auxiliary clamping role. Simultaneously, cylinder 34 drives the clamping head 35 to rise, and the outer wall of the clamping head 35 abuts against the guide slope 33 of the clamping block 32, thereby restricting the position of the clamping block 32 and ensuring that the clamping block 32 abuts against the inner wall of the bearing ring 8. As the clamping head 35 continues to rise, the cooperation between the outer periphery of cylinder 34 and the guide slope 33 pushes the clamping block 32 outward, allowing the clamping block 32 to also abut against the inner wall of the bearing ring 8 with a slightly larger inner diameter, thus increasing its usability.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
