Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and specifically to an inner ring grinding device for bearing processing. Background Art

[0002] In the field of bearing manufacturing, inner ring grinding is one of the key processes to improve the accuracy and performance of bearings. Traditional inner ring grinding devices for bearings mostly adopt fixed or simple reciprocating grinding structures. Their core design usually includes one or more grinding rollers, which make circular or linear reciprocating motions along the inner wall of the bearing body through a mechanical transmission or hydraulic drive system to achieve the removal of surface materials and the improvement of surface finish. Such devices have made certain progress in terms of automation and grinding efficiency, but they still have significant limitations in terms of grinding accuracy control, surface quality consistency, and adaptability.

[0003] Defects of the prior art:

[0004] Problem of local over-grinding: In traditional devices, the grinding rollers often act on the inner wall of the bearing with a fixed pressure or a simple periodic pressure, resulting in local over-grinding in the same area due to continuous pressure. This non-uniform material removal not only destroys the flatness of the inner wall surface but may also cause micro-cracks or stress concentration, affecting the fatigue life and rotational accuracy of the bearing.

[0005] Uneven grinding marks: Due to the lack of an effective grinding path planning and pressure control mechanism, existing devices are difficult to ensure that each contact is a new starting point during the grinding process, resulting in uneven grinding marks on the inner wall surface. This non-uniformity not only reduces the aesthetics of the bearing but may also affect the lubrication performance and sealing effect of the bearing due to inconsistent surface roughness. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an inner ring grinding device for bearing processing, which solves the technical problems mentioned in the background art.

[0012] As a further preference of this technical solution, the control member further includes a group of first positioning seats and a group of second positioning seats fixedly installed on the inner wall of the groove. Each group of first positioning seats and second positioning seats has two. A first rotating shaft is rotatably connected to the first positioning seat. A control motor fixedly installed on the mounting frame is arranged on one side of one of the first rotating shafts. A second rotating shaft is rotatably connected to the second positioning seat. A rotating block is fixedly installed at one end of the first rotating shaft.

[0013] As a further preference of this technical solution, the other end of the rotating block is rotatably connected with a V-shaped rod through a connecting shaft, and the two connecting shafts are connected through a linkage plate. The other end of the V-shaped rod is rotatably connected with a swing rod. The other end of the swing rod is fixedly connected with the second rotating shaft. The middle positions of the two V-shaped rods are rotatably connected with a movable plate through a mounting shaft. A row of push blocks whose positions correspond to those of the push blocks are arranged at the top of the movable plate.

[0014] As a further preferred embodiment of the present technical solution, a vertical rod is rotatably connected to one side of the top plate, and the upper end of the vertical rod is transmission-connected to the incomplete gear through a synchronous pulley transmission member, a U-shaped frame fixedly installed on the mounting seat is provided at the bottom of the vertical rod, and a knocking rod for knocking the bearing body is slidably connected to the U-shaped frame, and a connecting rod is rotatably connected to the knocking rod near one end of the vertical rod, and a movable rod is rotatably connected to the other end of the connecting rod, and the other end of the movable rod is sleeved on the vertical rod, and a protrusion is provided on the bottom surface of the movable rod, and a toggle rod that is rotationally adapted to the protrusion is fixedly connected to the bottom end of the vertical rod, and a third limit block located in the inner cavity of the U-shaped frame is fixedly connected to the outer wall of the knocking rod, and a third damping spring sleeved on the knocking rod is provided on one side of the third limit block.

[0015] As a further preferred embodiment of the present technical solution, a filter screen is provided on the surface of the mounting seat, the bearing body is placed on the filter screen, a first cylinder is fixedly installed on both sides of the mounting seat, and a pressure plate for fixing the bearing body is provided at the output end of the first cylinder.

[0016] Compared with the prior art, it has the following beneficial effects:

[0017] Through the coordinated action of the push block, tilting block and other components, the grinding roller can intermittently move toward one side of the inner wall of the bearing body for contact. Each moving contact is a new starting point for grinding, which avoids local over-grinding caused by continuous pressure and reduces the uneven depth of grinding marks, so that the entire inner wall surface is relatively evenly polished, thereby improving the overall flatness of the inner wall surface of the bearing body; the process of gradually deepening the grinding depth can accurately control the grinding amount, and the operator can reasonably adjust the parameters of the push block, tilting block and other components and the operating parameters of the servo motor according to the material, size and processing requirements of the bearing body, and accurately control the distance the grinding roller moves toward the inner wall and the grinding depth each time, so as to meet the grinding needs of the inner wall of the bearing body with different precision requirements, help remove tiny burrs, oxide layers and other defects, and avoid unnecessary damage to the inner wall, so as to ensure the accuracy and performance of the bearing.

[0018] The impact force is relatively small during the intermittent grinding process, and the load on the overall structure of the equipment and the transmission components is also reduced accordingly, which helps to maintain the stability and reliability of the equipment and reduce the occurrence of equipment failures. After the grinding of a position on the inner wall of the bearing body is completed, the control board drives the relevant components to move downward by starting the second cylinder, and the blocking of the push rod by the tilting block is released. The mounting plate, the moving plate, and the grinding roller move and reset under the elastic force of the first damping spring, which is convenient for subsequent grinding of a position under the inner wall of the bearing body. The driving motor drives the incomplete gear to rotate, and the spline rod, the mounting frame and other components are driven to rotate synchronously through the engagement with the large gear, so that the position of the grinding roller in the inner cavity of the bearing body can be adjusted to achieve continuous and efficient grinding operations.

[0019] The cooperative design of the inclined block and the push rod plays a role in limiting and blocking. When the push block rotates to not contact the mounting plate, the inclined block moves and resets under the elastic force of the second damping spring and blocks the push rod, preventing the mounting plate, the moving plate, and the grinding roller from moving away from the inner wall of the bearing body. This effectively avoids damage to the bearing body caused by the grinding roller moving too far away from the inner wall due to unexpected situations or penetrating too deeply into the inner wall due to excessive pressure, improving the safety of the processing process. The settings of the first damping spring and the second damping spring play a role in buffering and shock absorption, capable of absorbing the vibration and impact force generated during the grinding process, making the grinding process smoother. This not only helps improve the grinding quality but also reduces damage to the equipment caused by vibration, ensuring the safety of the operator.

[0020] The knocking rod moves towards the bearing body under the elastic force of the third damping spring and applies knocking. The generated vibration can directly act on the surface of the bearing body. This vibration can effectively shake off impurities such as abrasive grains, metal debris, or oxide scales attached to the surface of the bearing body during the grinding process. Compared with traditional cleaning methods, it can remove these attachments more quickly and thoroughly, improving the cleanliness of the bearing body. Timely cleaning of the attachments on the surface of the bearing body can prevent these impurities from causing secondary pollution to the bearing body during subsequent processing or use, avoiding impurities from entering the bearing interior and affecting its normal operation, thereby ensuring the performance and service life of the bearing.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: the present invention relates to an inner ring grinding device for bearing processing, the device mainly consists of a mounting seat 1 and a bearing body 3, the bearing body 3 is placed on the mounting seat 1, and a top plate 2 is fixedly installed above the mounting seat 1, and a grinding component 4 is arranged at the bottom of the top plate 2, which is responsible for grinding the inner wall of the bearing body 3;

[0032] To ensure cleanliness during the grinding process, a filter screen 11 is specifically provided on the surface of the mounting base 1. The bearing body 3 is placed on the filter screen 11. In addition, first cylinders 12 are fixedly installed on both sides of the mounting base 1, and pressing plates 13 are provided at their output ends for fixing the bearing body 3. The function of the filter screen 11 is to clean the waste chips generated during the grinding process. When the inner wall of the bearing body 3 needs to be ground, by activating the third cylinder 432, the mounting frame 42 is moved downward on the spline shaft 41, and thus the grinding roller 45 is moved to the position at the inner wall of the bearing body 3;

[0033] The grinding assembly 4 includes a spline shaft 41 rotatably installed on the mounting base 1. The spline shaft 41 is vertically provided with a mounting frame 42. One side of the mounting frame 42 is horizontally slidably connected with a moving plate 43. A control member is provided on the mounting frame 42, and this control member is responsible for intermittently moving the moving plate 43 towards the inner wall side of the bearing body 3. A servo motor 44 is fixedly installed on one side of the moving plate 43, and the output end of the servo motor 44 is fixedly connected with a grinding roller 45. The upper end of the spline shaft 41 is fixedly connected with a large gear 433. A driving motor 434 fixedly installed on the top plate 2 is provided on one side of the large gear 433, and the output end of the driving motor 434 is fixedly connected with an incomplete gear 435 meshing with the large gear 433. The incomplete gear 435 has one-quarter teeth. By using the incomplete gear 435 to intermittently drive the large gear 433 to rotate, the grinding position of the grinding roller 45 can be adjusted. When the grinding roller 45 is at the position of the inner wall of the bearing body 3, the servo motor 44 is activated to drive the grinding roller 45 to rotate synchronously, so that the grinding roller 45 grinds one place on the inner wall of the bearing body 3. Subsequently, by activating the driving motor 434 to drive the incomplete gear 435 to rotate synchronously, when the incomplete gear 435 rotates to mesh with the large gear 433, it can drive the large gear 433 to rotate, and then drive the spline shaft 41, the mounting frame 42, the moving plate 43, the servo motor 44, and the grinding roller 45 to rotate synchronously, thereby realizing efficient grinding of the inner wall of the bearing body 3;

[0034] The large gear 433 is located at the top and is fixedly connected with the rotating plate 431. A third cylinder 432 is installed at the bottom of one side of the rotating plate 431, and the output end of the third cylinder 432 is fixedly connected with the mounting frame 42. When the inner wall of the bearing body 3 needs to be ground, by starting the third cylinder 432, the mounting frame 42 can be driven to move downward along the spline shaft 41, so that the grinding roller 45 will move to the position of the inner wall of the bearing body 3;

[0035] The control member includes a groove formed in the mounting bracket 42. On both sides of the inner wall of the groove, there are fixedly connected fixing rods 46. A mounting plate 47 installed at the bottom of the moving plate 43 is slidably connected to the fixing rods 46. A first damping spring 48 is also sleeved on the fixing rods 46, and this spring is located on one side of the mounting plate 47. The bottom of the mounting plate 47 is fixedly connected with a push rod 49;

[0036] The control member further includes a support plate 410 fixedly installed on the inner wall of the groove. A row of sliding rods 411 are slidably connected to the support plate 410 in the vertical direction. At the top of the sliding rods 411, there is fixedly connected an inclined block 412 whose position corresponds to that of the push rod 49. A second damping spring 415 sleeved on the sliding rods 411 is arranged between the inclined block 412 and the support plate 410. At the bottom of the sliding rods 411, there are fixedly connected a first limit block 413 and a second limit block 414. A control plate 416 slidably installed on the sliding rods 411 is arranged between the first limit block 413 and the second limit block 414. Second cylinders 417 fixedly installed on the inner wall of the groove are arranged on both sides of the control plate 416;

[0037] The control member further includes a set of first positioning seats 418 and a set of second positioning seats 419 fixedly installed on the inner wall of the groove. There are two first positioning seats 418 and two second positioning seats 419 in each set. A first rotating shaft 420 is rotatably connected to the first positioning seat 418. On one side of one of the first rotating shafts 420, a control motor 430 fixedly installed on the mounting frame 42 is provided. A second rotating shaft 421 is rotatably connected to the second positioning seat 419. A rotating block 422 is fixedly installed at one end of the first rotating shaft 420. The other end of the rotating block 422 is rotatably connected to a V-shaped rod 424 through a connecting shaft 423. The two connecting shafts 423 are connected by a linkage plate 425. The other end of the V-shaped rod 424 is rotatably connected to a swing rod 427. The other end of the swing rod 427 is fixedly connected to the second rotating shaft 421. The middle positions of the two V-shaped rods 424 are rotatably connected to a movable plate 428 through a mounting shaft 426. At the top of the movable plate 428, there is a row of pushing blocks 429 corresponding to the pushing blocks 429. When the grinding roller 45 is located at the position of the inner wall of the bearing body 3, by turning on the moving plate 43, the control motor 430 drives the first rotating shaft 420 to rotate synchronously. The first rotating shaft 420 drives the rotating block 422 to rotate synchronously. At the same time, the rotating block 422 drives the other rotating block 422 to rotate through the connecting shaft 423 and the linkage plate 425. In this way, during the rotation process, the two rotating blocks 422 cooperate with the V-shaped rod 424 and the swing rod 427 to drive the movable plate 428 to rotate elliptically. Furthermore, the movable plate 428 drives the pushing blocks 429 to rotate elliptically synchronously. When the first pushing block 429 contacts the mounting plate 47, it can push the mounting plate 47, the moving plate 43, and the grinding roller 45 to move towards the inner wall side of the bearing body 3 and compress the first damping spring 48. At the same time, the push rod 49 will slide into contact with the inclined block 412, causing the push rod 49 to push the inclined block 412, the sliding rod 411, the first limiting block 413, and the second limiting block 414 to move downward and compress the second damping spring 415. Furthermore, the push rod 49 slides over the inclined block 412. When the pushing block 429 rotates to no longer contact the mounting plate 47, the inclined block 412 moves back to its original position under the elastic force of the second damping spring 415. And under the elastic force of the first damping spring 48, it can push the push rod 49 to contact the inclined block 412. At this time, the inclined block 412 blocks the push rod 49, thereby preventing the mounting plate 47, the moving plate 43, and the grinding roller 45 from moving away from the inner wall side of the bearing body 3. In this way, it reciprocally controls the mounting plate 47, the moving plate 43, and the grinding roller 45 to intermittently move and contact the inner wall side of the bearing body 3. In this way, when the grinding roller 45 gradually grinds the inner wall of the bearing body 3, the grinding depth of the inner wall of the bearing body 3 is gradually increased.

[0038] In an embodiment of the present invention, when performing a grinding operation on the inner wall of the bearing body 3, it is first necessary to start the third cylinder 432. This action causes the mounting bracket 42 to move downward along the spline rod 41, thereby driving the grinding roller 45 to reach a specified position on the inner wall of the bearing body 3;

[0039] When the grinding roller 45 reaches the designated position on the inner wall of the bearing body 3, the next operation is to start the moving plate 43. By controlling the operation of the motor 430, the first rotating shaft 420 starts to rotate synchronously. The rotation of the first rotating shaft 420 drives the rotating block 422 to rotate accordingly. Through the coordinated action of the connecting shaft 423 and the linkage plate 425, the rotating block 422 further drives another rotating block 422 to rotate. During the rotation process, the two rotating blocks 422 can achieve the elliptical rotational motion of the movable plate 428 by cooperating with the V-shaped rod 424 and the swing rod 427. The rotation of the movable plate 428 drives the pushing block 429 to perform a corresponding elliptical rotation. When the first pushing block 429 contacts the mounting plate 47, it pushes the mounting plate 47, the moving plate 43, and the grinding roller 45 to move towards the inner wall side of the bearing body 3, and compresses the first damping spring 48. At the same time, the push rod 49 makes a sliding contact with the inclined block 412, causing the push rod 49 to push the inclined block 412, the slide rod 411, the first limiting block 413, and the second limiting block 414 to move downward together and compress the second damping spring 415. Subsequently, the push rod 49 slides over the inclined block 412. When the pushing block 429 rotates to no longer contact the mounting plate 47, the inclined block 412 resets under the elastic force of the second damping spring 415, and under the elastic force of the first damping spring 48, it pushes the push rod 49 to contact the inclined block 412. At this time, the inclined block 412 plays a blocking role on the push rod 49 to prevent the mounting plate 47, the moving plate 43, and the grinding roller 45 from moving away from the inner wall side of the bearing body 3. Through this reciprocating control, the mounting plate 47, the moving plate 43, and the grinding roller 45 intermittently move and contact the inner wall of the bearing body 3, enabling the grinding roller 45 to gradually grind the inner wall of the bearing body 3 and gradually deepen the grinding depth. This intermittent moving contact avoids local over-grinding caused by continuous pressure. Each moving contact is a new starting point for grinding, ensuring that the entire inner wall surface can be relatively evenly ground, reducing the unevenness of the grinding marks caused by too long local grinding time, thereby improving the overall flatness of the inner wall surface of the bearing body 3. The process of gradually deepening the grinding depth can achieve precise control of the grinding amount. The operator can reasonably adjust the parameters of components such as the pushing block 429 and the inclined block 412 and the operating parameters of the servo motor 44 according to the material, size, and processing requirements of the bearing body 3, so as to precisely control the distance that the grinding roller 45 moves towards the inner wall each time and the grinding depth, meeting the inner wall grinding requirements of the bearing body 3 with different precision requirements. This fine grinding control method helps to remove tiny burrs, oxide layers, and other defects on the inner wall of the bearing body 3, while avoiding unnecessary damage to the inner wall, ensuring the precision and performance of the bearing. The matching design of the inclined block 412 and the push rod 49 plays a role of limiting and blocking. When the pushing block 429 rotates to not contact the mounting plate 47,The tilting block 412 moves back to its original position under the elastic force of the second damping spring 415 and blocks the push rod 49, preventing the mounting plate 47, the moving plate 43, and the grinding roller 45 from moving away from the inner wall of the bearing body 3. This mechanism effectively prevents the grinding roller 45 from moving too far away from the inner wall due to unexpected situations. At the same time, it also prevents the grinding roller 45 from penetrating too deeply into the inner wall due to excessive pressure, which may cause damage to the bearing body 3, improving the safety of the processing process. The settings of the first damping spring 48 and the second damping spring 415 play a role in buffering and shock absorption, capable of absorbing the vibrations and impact forces generated during the grinding process, making the grinding process more stable. This not only helps to improve the grinding quality but also reduces the damage to the equipment caused by vibrations, ensuring the safety of the operators. In this process, by turning on the servo motor 44 to drive the grinding roller 45 to rotate synchronously, the grinding roller 45 grinds a position on the inner wall of the bearing body 3;

[0040] After grinding a position on the inner wall of the bearing body 3, by starting the second cylinder 417, the control board 416 moves downward. The control board 416 cooperates with the second limiting block 414 to drive all the sliding rods 411, the first limiting block 413, and the tilting block 412 to move downward together, so that all the tilting blocks 412 no longer block the push rod 49. At this time, the mounting plate 47, the moving plate 43, and the grinding roller 45 move back to their original positions under the elastic force of the first damping spring 48, facilitating the subsequent grinding of the next position on the inner wall of the bearing body 3;

[0041] After grinding a position on the inner wall of the bearing body 3, the drive motor 434 drives the incomplete gear 435 to rotate synchronously. When the incomplete gear 435 rotates to mesh with the large gear 433, it can drive the large gear 433 to rotate, and then drive the spline shaft 41, the mounting bracket 42, the moving plate 43, the servo motor 44, and the grinding roller 45 to rotate synchronously, so as to adjust the position of the grinding roller 45 inside the bearing body 3, enabling the grinding roller 45 to grind the next position on the inner wall of the bearing body 3.

[0042] Embodiment 2: Combine Figure 2 、 Figure 4As shown, on the basis of the first embodiment, on one side of the top plate 2, there is a vertically rod 436 rotatably connected. The upper end of this vertically rod 436 is drivingly connected to the incomplete gear 435 through a synchronous pulley transmission member 438. At the bottom of the vertically rod 436, a U-shaped frame 437 fixedly installed on the mounting base 1 is provided. A knocking rod 439 for knocking the bearing body 3 is slidably connected to the U-shaped frame 437. One end of the knocking rod 439 close to the vertically rod 436 is rotatably connected to a linkage rod 440, and the other end of the linkage rod 440 is rotatably connected to a movable rod 441. The other end of the movable rod 441 is sleeved on the vertically rod 436, and a convex block 442 is provided on the bottom surface of the movable rod 441. At the bottom end of the vertically rod 436, a toggle rod 443 rotatably adapted to the convex block 442 is fixedly connected. In addition, a third limit block 444 located in the inner cavity of the U-shaped frame 437 is fixedly connected to the outer wall of the knocking rod 439. A third damping spring 445 sleeved on the knocking rod 439 is provided on one side of the third limit block 444.

[0043] In an embodiment of the present invention, when the drive motor 434 starts to operate and drives the incomplete gear 435 to rotate, the incomplete gear 435 will, through the action of the synchronous pulley transmission member 438, cause the vertically rod 436 to rotate synchronously. As the vertically rod 436 rotates, it will further drive the toggle rod 443 to rotate synchronously. During the rotation of the toggle rod 443, once it contacts the convex block 442, a force will be generated, and this force can cause the movable rod 441 to start rotating. While the movable rod 441 rotates, it will cooperate with the linkage rod 440, thereby driving the knocking rod 439 and the third limit block 444 to move together to the side away from the bearing body 3. During this process, the third damping spring 445 will be compressed. As the toggle rod 443 continues to rotate, the knocking rod 439 will move towards the bearing body 3 under the elastic force of the third damping spring 445 and apply a knock to the outer wall of the bearing body 3. The vibration generated by this knock can effectively shake off the abrasive grains, metal debris or oxide scales attached to the surface of the bearing body 3 during the grinding process, thereby achieving the purpose of cleaning the bearing body 3.
