Description

Technical Field

[0001] This invention belongs to the field of bearing manufacturing technology, and specifically relates to a method for manufacturing a wheel hub bearing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] The primary function of automotive wheel hub bearings is to bear weight and provide precise guidance for the rotation of the wheel hub. They withstand both axial and radial loads, making them a crucial component. Bearing installation, lubrication, sealing, and clearance adjustment are all performed on the automotive production line. During vehicle maintenance at repair shops, the bearings also require cleaning, lubrication, and adjustment. Wheel hub bearing units offer advantages such as easy assembly, eliminating the need for clearance adjustment, lightweight, compact structure, high load capacity, pre-lubrication for sealed bearings, elimination of external hub seals, and maintenance-free operation. They are widely used in passenger cars and are increasingly being adopted in heavy-duty trucks.

[0004] In the manufacturing process of automotive wheel hub bearings, workers often need to press-fit the wheel hub bearings. However, manual pressing can easily damage the wheel hub bearings, thereby reducing their precision and shortening their service life. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems in the prior art and provide a method for manufacturing a wheel hub bearing. This method involves placing an inner ring inside an outer ring, then installing balls between the inner and outer rings to complete the assembly of the inner and outer rings. Next, a bearing sleeve is clamped and fixed using clamping assembly one, while the assembled inner and outer rings are clamped and fixed using clamping assembly two. Then, an adjusting assembly controls the lowering of clamping assembly two, allowing the assembled inner and outer rings to pass through a through hole. Simultaneously, a pushing and lifting mechanism controls clamping assembly one to move the bearing sleeve upwards, allowing the assembled inner and outer rings to be inserted into the bearing sleeve, thus completing the assembly. Assembly is performed on an assembly table, which greatly improves the assembly accuracy of the wheel hub bearing and avoids damage during disassembly and assembly, ensuring the service life of the wheel hub bearing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A method for manufacturing a wheel hub bearing includes the following steps:

[0008] a. Pre-manufacturing preparations

[0009] First, prepare all the components required for bearing assembly and clean them. Then, reset the assembly table and clean it.

[0010] b. Combination of inner and outer rings

[0011] First, place the inner ring inside the outer ring, then install the ball bearings between the inner and outer rings, thus connecting the ball bearings between the inner and outer rings;

[0012] c. Clamping and fixing

[0013] 1) Clamping of bearing sleeves

[0014] An assembly cavity is provided at the bottom of the assembly table, and a clamping assembly is provided inside the assembly cavity. A top-pushing and lifting mechanism is provided at the bottom of the clamping assembly, and the clamping assembly clamps and fixes the bearing sleeve.

[0015] 2) Clamping of the assembled inner and outer rings

[0016] The top of the assembly table is provided with a through hole that communicates with the assembly cavity. An adjustment component is provided at the edge of the through hole at the top of the assembly table. A clamping component two is connected to the adjustment component. The clamping component two is clamped and fixed in the inner diameter of the inner ring assembled in step b.

[0017] d. Pressing

[0018] First, the adjusting component controls the clamping component two to move the assembled inner and outer rings downwards, so that the assembled inner and outer rings pass through the through hole into the assembly cavity. Then, the adjusting component is fixed, and the jacking and lifting mechanism controls the clamping component one to push the bearing sleeve upwards, so that the assembled inner and outer rings are pressed into the bearing sleeve.

[0019] e. Complete assembly

[0020] After the inner ring, outer ring, and bearing sleeve are assembled and fixed, release clamping component two, adjust component to control clamping component two to reset, push lifting mechanism to control clamping component one to descend and reset, then release clamping component one to complete the assembly.

[0021] Furthermore, in step c, the assembly platform includes a frame, a top-pushing lifting mechanism, an adjustment component, a clamping component one, and a clamping component two. The top of the frame has a through hole, and the bottom of the frame has an assembly cavity. The through hole communicates with the assembly cavity. The bottom of the top-pushing lifting mechanism is fixedly connected to the bottom of the assembly cavity, and the top of the top-pushing lifting mechanism is fixedly connected to the top of the assembly cavity. The clamping component one is fixedly connected in the top-pushing lifting mechanism and is set corresponding to the through hole. An adjustment component is set at the edge of the through hole on the top of the frame. The clamping component two is connected to the adjustment component and is set corresponding to the through hole. By setting up an assembly platform with an assembly cavity at its bottom, and a clamping assembly first inside the assembly cavity to clamp and fix the bearing sleeve, the assembly platform is equipped with a second clamping assembly. The assembly platform has through holes corresponding to the first and second clamping assemblies. The second clamping assembly is used to clamp the assembled inner and outer rings. An adjusting assembly controls the second clamping assembly to lower the assembled inner and outer rings. Through the through holes, the assembled inner and outer rings are inserted into the bearing sleeve, thus completing the manufacturing of the wheel hub bearing. Using this assembly platform, the pressing accuracy is greatly improved during the pressing process, and collisions between parts are avoided, thereby ensuring the service life of the assembled wheel hub bearing.

[0022] Furthermore, the jacking and lifting mechanism includes a base, a jacking platform, and a jacking component. The base is fixedly connected to the bottom of the assembly cavity. Both ends of the top of the base are equipped with fixed seats, and guide rods are fixedly connected to the fixed seats. The top of the guide rods passes through the jacking platform and is fixedly connected to the top of the assembly cavity. The bottom of the jacking platform extends downwards corresponding to the guide rods to form a guide seat. The guide rods pass through the guide seats. The bottom of the jacking component is fixedly connected to the base, and the output end of the jacking component is fixedly connected to the bottom of the jacking platform. The jacking component drives the jacking platform to lift and lower. The guide rods guide the lifting and lowering of the jacking platform, and the guide seats increase the contact area between the jacking platform and the guide column, thereby increasing the stability of the jacking platform's lifting and lowering.

[0023] Furthermore, the clamping assembly includes a push screw, a fixing block, and a clamping seat. The fixing block is circumferentially distributed on the push platform. The clamping seat is U-shaped, with anti-slip texture at one end and a connecting part at the other end. One end of the push screw has a limiting part, and the other end of the push screw passes through the fixing seat and is rotatably connected to the connecting part. The push screw drives the clamping seat to press against the outer wall of the bearing sleeve. Tightening the push screw causes it to move the clamping seat, clamping it against the outer wall of the bearing, thus fixing the bearing sleeve on the push platform. This increases the stability of the bearing sleeve during assembly, prevents it from shaking, and increases installation accuracy.

[0024] Furthermore, the jacking component employs a jacking cylinder, with its bottom fixedly connected to a base. An elastic connector is provided between the base and the jacking platform. This elastic connector includes an upper support, a lower support, and a spring. The lower support is fixedly connected to the base, and the upper support is correspondingly fixedly connected to the bottom of the jacking platform. The upper and lower supports are located on opposite sides of the jacking cylinder, and a spring is fixedly connected between them. The jacking cylinder controls the jacking platform to rise and fall along the direction of the guide rod. The elastic connector increases the stability of the jacking platform's rise and fall, while the upper and lower supports are used to mount the spring.

[0025] Furthermore, the adjustment assembly includes an adjustment frame, a Z-shaped connecting rod, and a ball screw. The bottom of the adjustment frame is fixedly connected to the top of the frame. The adjustment frame is circumferentially distributed on the outside of the through hole. An adjustment groove is provided on one side of the adjustment frame corresponding to the through hole. The ball screw is rotatably connected in the adjustment groove. A screw motor is provided on the top of the adjustment frame. The output end of the screw motor is connected to the ball screw. One end of the Z-shaped connecting rod is inserted into the adjustment groove and connected to the ball screw. The other end of the Z-shaped connecting rod is connected to the clamping assembly two. The screw motor controls the ball screw, thereby causing the Z-shaped connecting rod to drive the clamping assembly two to rise and fall along the adjustment groove, realizing the height adjustment of the clamping assembly two. When clamping the assembled inner and outer rings, the Z-shaped connecting rod drives the clamping assembly two to move to the top of the frame for easy clamping. After clamping, the clamping assembly two is controlled to fall, so that the jacking and lifting mechanism can control the bearing sleeve to rise, allowing the assembled inner and outer rings to be pressed into the bearing sleeve.

[0026] Furthermore, clamping assembly two includes a clamping plate, an adjusting component, and a clamping block. The other end of the Z-shaped connecting rod is fixedly connected to the outer wall of the clamping plate. A slide rail is distributed around the bottom circumference of the clamping plate. A slider is provided at the bottom of the clamping block, and the slider is slidably connected in the slide rail. The clamping block has anti-slip texture two corresponding to its inner ring. The adjusting component is fixedly connected to the clamping plate and is connected to the clamping block. The adjusting component drives the clamping block to slide and adjust along the direction of the slide rail, so that the clamping block is pressed against the inner diameter of the inner ring. The adjusting component controls the clamping block to be pressed against the inner diameter of the inner ring, thereby fixing the assembled outer ring and inner ring to the bottom of the clamping plate. The anti-slip texture two improves the clamping stability of clamping assembly two.

[0027] Furthermore, the adjusting component includes a fixed ring and an adjusting screw. Connecting blocks are distributed around the top circumference of the fixed ring, and these connecting blocks are fixedly connected to the bottom of the clamping plate, positioning the fixed ring below the slide rail. The end of the adjusting screw passes through the fixed ring and is fixedly connected to a tightening block. Locking nuts are screwed into both ends of the adjusting screw, and these nuts are tightened onto the fixed ring. The fixed ring is fixedly connected to the clamping plate via the connecting blocks. Loosening the locking nuts drives the adjusting screw, causing the tightening block to slide along the slide rail. This causes the tightening block to press against the inner diameter of the inner ring, thus fixing the assembled outer ring and inner ring to the bottom of the clamping plate. After tightening, the locking nuts are tightened to secure the adjusting screw.

[0028] Furthermore, the clamping plate is also equipped with positioning components, which position the assembled inner and outer rings and bearing sleeve during installation. These positioning components play a crucial role in the press-fitting process of the bearing sleeve and the assembled inner and outer rings, preventing misalignment and improving press-fitting accuracy.

[0029] Furthermore, the positioning component includes a positioning block, a connecting rod, an adjusting plate, and a fixing screw. The fixing screw is fixedly connected to the top of the clamping plate and passes through the adjusting plate, which is located above the clamping plate. Fixing nuts are screwed into both ends of the fixing screw, tightened at the top and bottom of the adjusting plate. The top of the connecting rod is fixedly connected to the bottom of the adjusting plate, and the bottom of the connecting rod passes through the clamping plate and is fixedly connected to the positioning block. After the assembled inner and outer rings are clamped, the positioning block rests against the top surfaces of the inner and outer rings. By loosening the fixing nuts, the adjusting plate is driven to move up and down along the direction of the fixing screw. The adjusting plate, through the connecting rod, drives the positioning block to move up and down, so that the positioning block rests against the top of the assembled inner and outer rings. After adjustment, the fixing nuts are tightened at the top and bottom of the adjusting plate to fix it. During the press-fitting process, after the assembled inner and outer rings are pressed into the bearing sleeve, the top of the bearing sleeve rests against the positioning block for positioning, preventing misalignment during press-fitting.

[0030] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0031] This invention completes the assembly of the inner and outer rings by placing the inner ring inside the outer ring and then inserting the balls between them. The bearing sleeve is then clamped and fixed using clamping assembly one, while the assembled inner and outer rings are clamped and fixed using clamping assembly two. Next, an adjusting assembly controls the lowering of clamping assembly two, allowing the assembled inner and outer rings to pass through a through hole. Simultaneously, a pushing and lifting mechanism controls clamping assembly one to move the bearing sleeve upwards, allowing the assembled inner and outer rings to be inserted into the bearing sleeve, thus completing the assembly. Assembly is performed on an assembly table, significantly improving the assembly precision of the wheel hub bearing and preventing damage during disassembly and assembly, thereby ensuring the service life of the wheel hub bearing.

[0032] In step c of this invention, the assembly table includes a frame, a top-pushing and lifting mechanism, an adjustment component, a clamping component one, and a clamping component two. The top of the frame has a through hole that communicates with the assembly cavity. The bottom of the frame has an assembly cavity. The bottom of the top-pushing and lifting mechanism is fixedly connected to the bottom of the assembly cavity, and the top of the top-pushing and lifting mechanism is fixedly connected to the top of the assembly cavity. The clamping component one is fixedly connected to the top-pushing and lifting mechanism and is set corresponding to the through hole. An adjustment component is set at the edge of the through hole on the top of the frame. The clamping component two is connected to the adjustment component and is set corresponding to the through hole. By setting up an assembly platform with an assembly cavity at its bottom, and a clamping assembly first inside the assembly cavity to clamp and fix the bearing sleeve, the assembly platform is equipped with a second clamping assembly. The assembly platform has through holes corresponding to the first and second clamping assemblies. The second clamping assembly is used to clamp the assembled inner and outer rings. An adjusting assembly controls the second clamping assembly to lower the assembled inner and outer rings. Through the through holes, the assembled inner and outer rings are inserted into the bearing sleeve, thus completing the manufacturing of the wheel hub bearing. Using this assembly platform, the pressing accuracy is greatly improved during the pressing process, and collisions between parts are avoided, thereby ensuring the service life of the assembled wheel hub bearing.

[0033] In this invention, the positioning component includes a positioning block, a connecting rod, an adjusting plate, and a fixing screw. The fixing screw is fixedly connected to the top of the clamping plate and passes through the adjusting plate, which is located above the clamping plate. Fixing nuts are screwed into both ends of the fixing screw, tightened at the top and bottom of the adjusting plate. The top of the connecting rod is fixedly connected to the bottom of the adjusting plate, and the bottom of the connecting rod passes through the clamping plate and is fixedly connected to the positioning block. After the assembled inner and outer rings are clamped, the positioning block rests against the top surfaces of the inner and outer rings. By loosening the fixing nuts, the adjusting plate is driven to move up and down along the direction of the fixing screw. The adjusting plate, through the connecting rod, drives the positioning block to move up and down, so that the positioning block rests against the top of the assembled inner and outer rings. After adjustment, the fixing nuts are tightened at the top and bottom of the adjusting plate to fix it. During the pressing process, after the assembled inner and outer rings are pressed into the bearing sleeve, the top of the bearing sleeve rests against the positioning block for positioning, preventing misalignment during pressing.

Detailed Implementation

[0045] like Figures 1 to 9 As shown, this invention provides a method for manufacturing a wheel hub bearing, comprising the following steps:

[0046] a. Pre-manufacturing preparations

[0047] First, prepare all the components required for bearing assembly and clean them. Then, reset the assembly table and clean it.

[0048] b. Combination of inner and outer rings

[0049] First, place the inner ring inside the outer ring, then install the ball bearings between the inner and outer rings, thus connecting the ball bearings between the inner and outer rings;

[0050] c. Clamping and fixing

[0051] 1) Clamping of bearing sleeves

[0052] An assembly cavity is provided at the bottom of the assembly table, and a clamping assembly is provided inside the assembly cavity. A top-pushing and lifting mechanism is provided at the bottom of the clamping assembly, and the clamping assembly clamps and fixes the bearing sleeve.

[0053] 2) Clamping of the assembled inner and outer rings

[0054] The top of the assembly table is provided with a through hole that communicates with the assembly cavity. An adjustment component is provided at the edge of the through hole at the top of the assembly table. A clamping component two is connected to the adjustment component. The clamping component two is clamped and fixed in the inner diameter of the inner ring assembled in step b.

[0055] d. Pressing

[0056] First, the adjusting component controls the clamping component two to move the assembled inner and outer rings downwards, so that the assembled inner and outer rings pass through the through hole into the assembly cavity. Then, the adjusting component is fixed, and the jacking and lifting mechanism controls the clamping component one to push the bearing sleeve upwards, so that the assembled inner and outer rings are pressed into the bearing sleeve.

[0057] e. Complete assembly

[0058] After the inner ring, outer ring, and bearing sleeve are assembled and fixed, release clamping component two, adjust component to control clamping component two to reset, push lifting mechanism to control clamping component one to descend and reset, then release clamping component one to complete the assembly.

[0059] In step c, the assembly table 1 includes a frame 2, a top-pushing lifting mechanism 3, an adjustment component 4, a clamping component 1 5, and a clamping component 2 6. The top of the frame 2 is provided with a through hole 7, and the bottom of the frame 2 is provided with an assembly cavity 8. The through hole 7 communicates with the assembly cavity 8. The bottom of the top-pushing lifting mechanism 3 is fixedly connected to the bottom of the assembly cavity 8, and the top of the top-pushing lifting mechanism 3 is fixedly connected to the top of the assembly cavity 8. The clamping component 1 5 is fixedly connected in the top-pushing lifting mechanism 3 and is set corresponding to the through hole 7. The top of the frame 2 is provided with an adjustment component 4 located at the edge of the through hole 7. The clamping component 2 6 is connected to the adjustment component 4 and is set corresponding to the through hole 7. By setting up an assembly table 1, and an assembly cavity 8 at the bottom of the assembly table 1, a clamping assembly 5 is set in the assembly cavity 8. The clamping assembly 5 is used to clamp and fix the bearing sleeve 48. The clamping assembly 5 is controlled by the top pushing and lifting mechanism 3 to drive the bearing sleeve 48 to rise and fall. A clamping assembly 6 is set on the assembly table 1. The assembly table 1 has through holes 7 corresponding to the clamping assembly 5 and the clamping assembly 6. The clamping assembly 6 is used to clamp the assembled inner ring 46 and outer ring 47. The adjusting component 4 controls the clamping assembly 6 to drive the assembled inner ring 46 and outer ring 47 to fall. Through the setting of the through holes 7, the assembled inner ring 46 and outer ring 47 are put into the bearing sleeve 48, thereby completing the manufacturing of the wheel hub bearing. By using this assembly table 1, the pressing accuracy is greatly improved during the pressing process, and the collision between parts is avoided, thereby ensuring the service life of the assembled wheel hub bearing.

[0060] The jacking and lifting mechanism 3 includes a base 9, a jacking platform 10, and a jacking component 11. The base 9 is fixedly connected to the bottom of the assembly cavity 8. Both ends of the top of the base 9 are provided with fixed seats 12, and guide rods 13 are fixedly connected to the fixed seats 12. The top of the guide rods 13 passes through the jacking platform 10 and is fixedly connected to the top of the assembly cavity 8. The bottom of the jacking platform 10 extends downwards corresponding to the guide rods 13 to form a guide seat. The guide rods 13 pass through the guide seats 14. The bottom of the jacking component 11 is fixedly connected to the base 9, and the output end of the jacking component 11 is fixedly connected to the bottom of the jacking platform 10. The jacking component 11 is used to drive the jacking platform 10 to lift and lower. The guide rods 13 guide the lifting and lowering of the jacking platform 10. The guide seats 14 increase the contact area between the jacking platform 10 and the guide column, thereby increasing the stability of the lifting and lowering of the jacking platform 10. The pusher 11 uses a pusher cylinder 21, the bottom of which is fixedly connected to the base 9. An elastic connector is provided between the base 9 and the pusher platform 10. The elastic connector includes an upper support 22, a lower support 23, and a spring 24. The lower support 23 is fixedly connected to the base 9, and the upper support 22 is fixedly connected to the bottom of the pusher platform 10 corresponding to the lower support 23. The upper support 22 and the lower support 23 are respectively located on both sides of the pusher cylinder 21, and the spring 24 is fixedly connected between the upper support 22 and the lower support 23. The pusher cylinder 21 controls the pusher platform 10 to rise and fall along the direction of the guide rod 13. The elastic connector increases the stability of the pusher platform 10's rise and fall, and the upper support 22 and the lower support 23 are used to install the spring 24.

[0061] The clamping assembly 5 includes a push screw 15, a fixing block 16, and a clamping seat 17. The fixing block 16 is circumferentially distributed on the push table 10. The clamping seat 17 is U-shaped, with anti-slip texture 18 at one end and a connecting part 19 at the other end. One end of the push screw 15 has a limiting part 20, and the other end of the push screw 15 passes through the fixing seat 12 and is rotatably connected to the connecting part 19. The push screw 15 drives the clamping seat 17 to press against the outer wall of the bearing sleeve 48. Tightening the push screw 15 causes the clamping seat 17 to move, clamping it against the outer wall of the bearing, thus fixing the bearing sleeve 48 on the push table 10. This increases the stability of the bearing sleeve 48 during assembly, prevents it from shaking, and increases installation accuracy.

[0062] The adjustment assembly 4 includes an adjustment frame 25, a Z-shaped connecting rod 26, and a ball screw 27. The bottom of the adjustment frame 25 is fixedly connected to the top of the frame 2. The adjustment frame 25 is circumferentially distributed on the outside of the through hole 7. The adjustment frame 25 has an adjustment groove 28 on one side corresponding to the through hole 7. The ball screw 27 is rotatably connected in the adjustment groove 28. The top of the adjustment frame 25 is equipped with a screw motor 29. The output end of the screw motor 29 is connected to the ball screw 27. One end of the Z-shaped connecting rod 26 is inserted into the adjustment groove 28 and connected to the ball screw 27. The other end of the Z-shaped connecting rod 26 is connected to the clamping assembly 6. The lead screw motor 29 controls the ball screw 27, which causes the Z-shaped connecting rod 26 to drive the clamping assembly 26 to rise and fall along the adjusting groove 28, thus making the height of the clamping assembly 26 adjustable. When clamping the assembled inner ring 46 and outer ring 47, the Z-shaped connecting rod 26 drives the clamping assembly 26 to move above the frame 2 for easy clamping. After clamping, the clamping assembly 26 is controlled to fall, so that the lifting mechanism 3 can control the bearing sleeve 48 to rise, so that the assembled inner ring 46 and outer ring 47 can be pressed into the bearing sleeve 48.

[0063] The clamping assembly 26 includes a clamping plate 30, an adjusting member 31, and a clamping block 32. The other end of the Z-shaped connecting rod 26 is fixedly connected to the outer wall of the clamping plate 30. A slide rail 33 is distributed around the bottom circumference of the clamping plate 30. A slider 34 is provided at the bottom of the clamping block 32, and the slider 34 is slidably connected to the slide rail 33. The clamping block 32 has anti-slip texture 35 corresponding to the inner ring 46. The adjusting member 31 is fixedly connected to the clamping plate 30 and is connected to the clamping block 32. The adjusting member 31 drives the clamping block 32 to slide and adjust along the direction of the slide rail 33, so that the clamping block 32 is pressed against the inner diameter of the inner ring 46. The adjusting member 31 controls the clamping block 32 to be pressed against the inner diameter of the inner ring 46, thereby fixing the assembled outer ring 47 and inner ring 46 to the bottom of the clamping plate 30. The anti-slip texture 35 improves the stability of the clamping assembly 26.

[0064] The adjusting component 31 includes a fixed ring 36 and an adjusting screw 37. Connecting blocks 38 are distributed around the top circumference of the fixed ring 36, and are fixedly connected to the bottom of the clamping plate 30, positioning the fixed ring 36 below the slide rail 33. The end of the adjusting screw 37 passes through the fixed ring 36 and is fixedly connected to a tightening block 32. Locking nuts 39 are screwed into both ends of the adjusting screw 37 and tightened onto the fixed ring 36. The fixed ring 36 is fixedly connected to the clamping plate 30 via the connecting blocks 38. Loosening the locking nuts 39 drives the adjusting screw 37, causing the tightening block 32 to slide along the slide rail 33, pressing against the inner diameter of the inner ring 46. This achieves a fixed connection between the assembled outer ring 47 and inner ring 46 at the bottom of the clamping plate 30. After tightening, the locking nuts 39 are tightened to secure the adjusting screw 37.

[0065] The clamping plate 30 is also connected to a positioning element 40, which positions the assembled inner ring 46, outer ring 47, and bearing sleeve 48 during installation. The positioning element 40 plays a positioning role during the press-fitting process of the bearing sleeve 48 and the assembled inner ring 46 and outer ring 47, avoiding misalignment and improving press-fitting accuracy. The positioning component 40 includes a positioning block 41, a connecting rod 42, an adjusting plate 43, and a fixing screw 44. The fixing screw 44 is fixedly connected to the top of the clamping plate 30 and passes through the adjusting plate 43, which is located above the clamping plate 30. Fixing nuts 45 are screwed into both ends of the fixing screw 44 and tightened at the upper and lower ends of the adjusting plate 43. The top of the connecting rod 42 is fixedly connected to the bottom of the adjusting plate 43, and the bottom of the connecting rod 42 passes through the clamping plate 30 and is fixedly connected to the positioning block 41. After the assembled inner ring 46 and outer ring 47 are clamped, the positioning block 41 abuts against the top surface of the inner ring 46 and outer ring 47. By loosening the fixing nut 45, the driving adjustment plate 43 is raised and lowered along the direction of the fixing screw 44. The adjustment plate 43 drives the positioning block 41 to be raised and lowered through the connecting rod 42, so that the positioning block 41 abuts against the top of the assembled inner ring 46 and outer ring 47. After the adjustment is completed, the fixing nut 45 is tightened on the upper and lower ends of the adjustment plate 43 to fix the adjustment plate 43. During the pressing process, after the assembled inner ring 46 and outer ring 47 are pressed into the bearing sleeve 48, the top of the bearing sleeve 48 abuts against the positioning block 41 for positioning, thus avoiding misalignment during pressing.

[0066] This invention completes the assembly of the inner ring 46 and outer ring 47 by placing the inner ring 46 inside the outer ring 47 and then installing the ball bearings between the inner ring 46 and the outer ring 47. The bearing sleeve 48 is then clamped and fixed using clamping assembly 5, while the assembled inner ring 46 and outer ring 47 are clamped and fixed using clamping assembly 2 6. Next, adjusting assembly 4 controls clamping assembly 2 6 to descend, allowing the assembled inner ring 46 and outer ring 47 to pass through the through hole 7. Simultaneously, the pushing and lifting mechanism 3 controls clamping assembly 5 to move the bearing sleeve 48 upward, allowing the assembled inner ring 46 and outer ring 47 to be inserted into the bearing sleeve 48, thus completing the assembly. Assembly is performed using assembly table 1, which greatly improves the assembly accuracy of the wheel hub bearing and avoids damage to the wheel hub bearing during disassembly and assembly, ensuring the service life of the wheel hub bearing.

[0067] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
