Description

Technical Field

[0001] This utility model belongs to the field of bearing manufacturing technology, and in particular relates to a grinding device for the production of self-aligning roller bearings. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "A Grinding Device for the Production of Self-Aligning Roller Bearings," application number "CN217648061U." This patent mainly involves setting up a dual-axis motor, a first grinding wheel, a second grinding wheel, a sealing cover, a moving plate, a moving frame, a sliding plate, a fixed column, and an elastic rod. When the dual-axis motor drives the first and second grinding wheels to rotate and grind the workpiece, it also drives the fixed column to rotate. When the fixed column rotates and contacts the moving plate, the device drives the workpiece to move back and forth through the moving frame, increasing the contact area between the workpiece and the first and second grinding wheels, ensuring the grinding effect of the first and second grinding wheels, and ensuring the service life of the first and second grinding wheels.

[0003] However, when the above-mentioned device grinds the bearing, the grinding direction is relatively singular, which leads to an unsatisfactory grinding effect on the bearing surface. The singular grinding direction means that during the grinding process, it is impossible to fully cover all angles and different surface features of the bearing, which can easily lead to uneven wear in certain areas or the creation of dead corners during the grinding process, thereby affecting the overall performance and service life of the bearing. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding device for the production of self-aligning roller bearings, which solves the problem that the grinding direction of the bearing is relatively singular when the above-mentioned device grinds the bearing, resulting in an unsatisfactory grinding effect on the bearing surface. The singular grinding direction means that it is impossible to fully cover all angles and different surface features of the bearing during the grinding process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a grinding device for the production of self-aligning roller bearings, including a base plate and a bearing, wherein a grinding mechanism and a fixing mechanism are provided on the base plate;

[0007] The grinding mechanism includes a vertical plate fixedly connected to the top surface of the base plate. A fixing plate is fixedly connected to the right side of the vertical plate. A motor is fixedly connected to the inner wall of the fixing plate. A rotating shaft is fixedly connected to the output end of the motor via a coupling. Two connecting plates are fixedly connected to the outer wall of the rotating shaft. A rotating rod is rotatably connected through the two connecting plates. A grinding roller is fixedly connected to the outer wall of the rotating rod. A gear is fixedly connected to the outer wall of the rotating rod. A rotating rod is rotatably connected through the two connecting plates. A grinding roller is fixedly connected to the outer wall of the rotating rod. A gear is fixedly connected to the outer wall of the rotating rod. Gears 1 and 2 mesh with each other. The outer walls of grinding roller 1 and grinding roller 2 are respectively in contact with the outer wall and inner wall of the bearing.

[0008] Furthermore, the fixing mechanism includes three fixing rods fixedly connected to the top surface of the base plate, and internal gear rings are fixedly connected to the top ends of the three fixing rods, the internal gear rings meshing with a gear.

[0009] Furthermore, two support plates are fixedly connected to the right side of the upright plate, and the rotating shaft passes through the two support plates. The two support plates are slidably connected to the top and bottom surfaces of the two connecting plates, respectively.

[0010] Furthermore, the inner wall of the upright plate has two trapezoidal grooves, and the inner walls of the two trapezoidal grooves are slidably connected to a movable plate.

[0011] Furthermore, a support plate is fixedly connected to the right side of the movable plate, an electric push rod is fixedly connected to the right side of the movable plate, a rubber pad is fixedly connected to the output end of the electric push rod, a rubber pad is fixedly connected to the bottom surface of the support plate, the rubber pad is located to the left of the rubber pad, and the gear and the rubber pad are in contact with the outer wall and inner wall of the bearing, respectively.

[0012] Furthermore, a second motor is fixedly connected to the right side of the upright plate, and a second rotating shaft is fixedly connected to the output end of the second motor via a coupling. A disc is fixedly connected to the left end of the second rotating shaft.

[0013] Furthermore, an eccentric shaft is fixedly connected to the left side of the disk, and a hinge plate is rotatably connected to the outer wall of the eccentric shaft. A connecting shaft is fixedly connected to the left side of the movable plate, and the side of the hinge plate away from the movable plate is rotatably sleeved on the outer wall of the connecting shaft.

[0014] This utility model has the following beneficial effects:

[0015] By incorporating a grinding mechanism, when motor one on the drive plate drives shaft one to rotate, it can drive two connecting plates to rotate. Under the action of gear one and internal gear ring, rotating rod one rotates within the internal gear ring. Gear one drives rotating rod one to rotate, and simultaneously drives gear two and rotating rod two to rotate. At this time, grinding roller one and grinding roller two rotate in opposite directions, allowing grinding roller one and grinding roller two to grind the inner and outer walls of the bearing. This enables the inner and outer walls of the bearing to be ground simultaneously, greatly improving the grinding efficiency of the bearing.

[0016] With a fixed mechanism, two support plates cooperate to support two rotating connecting plates. The trapezoidal groove and the moving plate cooperate to allow the moving plate to move vertically up and down only on the inner wall of the trapezoidal groove. When the first pair of bearings is being polished by the drive motor, the second drive motor can drive the second rotating shaft and the disc to rotate. With the cooperation of the eccentric shaft, hinge plate and connecting shaft, the moving plate is driven to move up and down reciprocally on the inner wall of the trapezoidal groove. This causes the bearing on the moving plate to move up and down reciprocally between the first and second polishing rollers. This reciprocating motion not only ensures that the bearing surface is in uniform contact with the two polishing rollers, achieving finer polishing, but also further improves the polishing effect and efficiency of the bearing.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a grinding device for the production of self-aligning roller bearings, including a base plate 1 and a bearing 4. A grinding mechanism 2 and a fixing mechanism 3 are provided on the base plate 1.

[0028] The grinding mechanism 2 includes a vertical plate 21 fixedly connected to the top surface of the base plate 1. A fixing plate 22 is fixedly connected to the right side of the vertical plate 21. A motor 23 is fixedly connected to the inner wall of the fixing plate 22. The output end of the motor 23 is fixedly connected to a rotating shaft 24 via a coupling. Two connecting plates 25 are fixedly connected to the outer wall of the rotating shaft 24. A rotating rod 26 rotatably passes through the two connecting plates 25. A grinding roller 27 is fixedly connected to the outer wall of the rotating rod 26. A gear 28 is fixedly connected to the outer wall of the rotating rod 26. A rotating rod 29 rotatably passes through the two connecting plates 25. A grinding roller 291 is fixedly connected to the outer wall of the rotating rod 29. A gear 292 is fixedly connected to the outer wall of the rotating rod 29. Gears 28 and 292 interact with each other. The outer walls of grinding roller 27 and grinding roller 291 are respectively in contact with the outer and inner walls of bearing 4. With the grinding mechanism 2, when the motor 23 on the drive plate 22 drives the rotating shaft 24 to rotate, it can drive the two connecting plates 25 to rotate. Under the action of gear 28 and internal gear ring 32, the rotating rod 26 rotates in the internal gear ring 32. Gear 28 drives the rotating rod 26 to rotate, and at the same time drives gear 292 and rotating rod 29 to rotate. At this time, the rotation directions of grinding roller 27 and grinding roller 291 are opposite, so that grinding roller 27 and grinding roller 291 grind the inner and outer walls of bearing 4, so that the inner and outer walls of bearing 4 can be ground at the same time, which greatly improves the grinding efficiency of bearing 4.

[0029] The fixing mechanism 3 includes three fixing rods 31 fixedly connected to the top surface of the base plate 1. An internal gear ring 32 is fixedly connected to the top of each fixing rod 31, and the internal gear ring 32 meshes with a gear 28. Two support plates 33 are fixedly connected to the right side of the upright plate 21. A rotating shaft 24 rotatably passes through the two support plates 33. The two support plates 33 are slidably connected to the top and bottom surfaces of the two connecting plates 25, respectively. Two trapezoidal grooves 34 are formed on the inner wall of the upright plate 21. A movable plate 35 is slidably connected to the inner wall of the two trapezoidal grooves 34. A support plate 36 is fixedly connected to the right side of the movable plate 35. An electric push rod 37 is fixedly connected to the right side of the movable plate 35. A rubber pad 38 is fixedly connected to the output end of the electric push rod 37. A rubber pad 39 is fixedly connected to the bottom surface of the support plate 36. The first rubber pad 38 is located to the left of the second rubber pad 39. The first gear 28 and the second rubber pad 39 are in contact with the outer and inner walls of the bearing 4, respectively. A motor 391 is fixedly connected to the right side of the upright plate 21. A rotating shaft 392 is fixedly connected to the output end of the motor 391 through a coupling. A disc 393 is fixedly connected to the left end of the rotating shaft 392. An eccentric shaft 394 is fixedly connected to the left side of the disc 393. A hinge plate 395 is rotatably connected to the outer wall of the eccentric shaft 394. A connecting shaft 396 is fixedly connected to the left side of the movable plate 35. The side of the hinge plate 395 away from the movable plate 35 is rotatably sleeved on the connecting shaft 396. On the outer wall, a fixing mechanism 3 is provided, and two support plates 33 cooperate with each other to support the two rotating connecting plates 25. The trapezoidal groove 34 and the moving plate 35 cooperate with each other, so that the moving plate 35 can only move vertically up and down on the inner wall of the trapezoidal groove 34. When the drive motor 1 23 grinds the bearing 4, the drive motor 2 391 can drive the rotating shaft 2 392 and the disc 393 to rotate. With the cooperation of the eccentric shaft 394, the hinge plate 395 and the connecting shaft 396, the moving plate 35 is driven to move up and down reciprocally on the inner wall of the trapezoidal groove 34, so that the bearing 4 on the moving plate 35 moves up and down reciprocally between the grinding roller 1 27 and the grinding roller 2 291. This up and down reciprocating motion can not only ensure that the surface of the bearing 4 is in uniform contact with the two grinding rollers, but also achieve more fine grinding, thereby further improving the grinding effect and grinding efficiency of the bearing 4.

[0030] One specific application of this embodiment is as follows: Before grinding the bearing 4, the bearing 4 can be placed between the rubber pad 39 and the rubber pad 38 from the bottom of the two grinding rollers 27. At the same time, the inner and outer walls of the bearing 4 are in contact with the grinding roller 291 and the grinding roller 27, respectively. At this time, the electric push rod 37 can be driven to move the rubber pad 38 to the right, so that the rubber pad 38 is tightly attached to the outer wall of the bearing 4, and the rubber pad 39 and the rubber pad 38 move closer to each other to fix the bearing 4.

[0031] With the grinding mechanism 2 in place, when the motor 23 on the drive plate 22 drives the rotating shaft 24 to rotate, it can drive the two connecting plates 25 to rotate. Under the action of the gear 28 and the internal gear ring 32, the rotating rod 26 rotates in the internal gear ring 32. The gear 28 drives the rotating rod 26 to rotate, and at the same time drives the gear 292 and the rotating rod 29 to rotate. At this time, the grinding roller 27 and the grinding roller 291 rotate in opposite directions, so that the grinding roller 27 and the grinding roller 291 grind the inner and outer walls of the bearing 4, so that the inner and outer walls of the bearing 4 can be ground at the same time, which greatly improves the grinding efficiency of the bearing 4.

[0032] With the fixed mechanism 3 in place, the two support plates 33 cooperate to support the two rotating connecting plates 25. The trapezoidal groove 34 and the moving plate 35 cooperate to allow the moving plate 35 to move vertically up and down only on the inner wall of the trapezoidal groove 34. When the drive motor 23 grinds the bearing 4, the drive motor 391 can drive the rotating shaft 392 and the disc 393 to rotate. With the cooperation of the eccentric shaft 394, the hinge plate 395 and the connecting shaft 396, the moving plate 35 is driven to move up and down reciprocally on the inner wall of the trapezoidal groove 34. This causes the bearing 4 on the moving plate 35 to move up and down reciprocally between the grinding roller 27 and the grinding roller 291. This reciprocating motion not only ensures that the surface of the bearing 4 is in uniform contact with the two grinding rollers, achieving finer grinding, but also further improves the grinding effect and grinding efficiency of the bearing 4.
