Description
Technical Field
[0001] This invention belongs to the technical field of bearing assembly equipment, specifically an automatic assembly equipment and method for bearing processing. Background Technology
[0002] Automatic bearing ball assembly equipment (also known as automatic bearing ball loading machine) is the core assembly equipment in the bearing automated production line. It is mainly used to complete the positioning of the inner and outer rings of the bearing, automatic feeding of steel balls and batch assembly operations. It can replace manual assembly methods and effectively improve the automation level and production efficiency of bearing assembly. It is now widely used in the field of precision bearing batch processing.
[0003] However, existing traditional automated assembly equipment still has some shortcomings in actual use, making it difficult to meet the production needs of bearings of various specifications.
[0004] Firstly, the steel ball conveying space in traditional equipment has a fixed structure, which cannot flexibly adjust the volume according to the assembly quantity requirements of steel balls for different specifications of bearings. For example, heavy-duty bearings and silent precision bearings of the same external size and with the same steel ball diameter can meet different performance requirements by varying the number of steel balls. This means the equipment can only be adapted to the production of a single type of bearing, resulting in poor equipment versatility and difficulty in meeting the batch processing needs of multiple types and differentiated bearings.
[0005] For example, Chinese patent application number CN202421056882.9, entitled "An Automatic Ball Loading Machine for Full-Ball Bearings," discloses that "to solve the above-mentioned technical problems, this utility model provides an automatic ball loading machine for full-ball bearings, including a base and a mounting plate disposed on the base... driving a ball-pulling rod to move the balls filled into the bearing," achieving the technical effect that "the beneficial effect brought by this utility model is: this utility model can significantly improve production efficiency... improving production efficiency and product quality." However, it does not disclose that the upper fixing block, lower fixing block, and ball feeding mechanism are all adjustable to adapt to the ball assembly requirements of different types and models of bearings.
[0006] Secondly, traditional equipment does not have a dedicated steel ball diversion and guiding structure. During the process of pushing and falling in batches, steel balls are prone to swarming and piling up. This not only causes the material to be blocked in the conveying pipeline and the material to be fed intermittently, but also results in the steel balls being arranged in a messy and disorderly manner.
[0007] For example, Chinese patent application number CN202311721980.X, patent subject name: an automatic assembly device for bearing processing, discloses "
[0012] At this time, the filling mechanism pushes the balls downward to fall between the outer ring and the inner ring, while the L-shaped extrusion block in the filling mechanism extrudes the positioning vertical plate, causing the positioning vertical plate to move away from the discharge pipe, the positioning vertical plate pushes the inner ring to move, so that the inner ring contacts the inner wall of the outer ring, thereby forming a crescent-shaped gap between the outer ring and the inner ring... The inner ring pushes the balls to move, while the striking head continuously strikes the outer ring, so that the balls can be well stuck between the outer ring and the inner ring. When the inner ring moves to the coaxial position with the outer ring, the assembly of the bearing outer ring, inner ring and balls is completed." Although this structure of continuous striking by the striking head can solve the problem of steel balls not accumulating after falling, its striking structure requires a power source, making the structure complex. Summary of the Invention
[0008] To address the problems mentioned in the background art, such as the lack of compatible bearing models, poor versatility, lack of flow guidance, and chaotic arrangement of steel balls, this invention provides an automatic assembly device and method for bearing processing.
[0009] To achieve the above objectives, the present invention provides the following technical solution: An automated assembly device for bearing processing includes The worktable has a shifting device on its upper surface, and an assembly table on the upper surface of the shifting device. The assembly table has a clamping cavity and a driving cavity inside, and the clamping cavity has a clamping device for fixing the bearing. The discharge component is vertically located above the gap between the outer ring shell and the inner ring shell. A lifting assembly is provided on the upper outer side of the discharge component, and a pushing device for pushing the rolling ball downward is provided at the top of the discharge component. The moving component is located within the drive cavity; The push block slides horizontally and extends to the bottom end face of the clamping cavity. The push block is inserted into the inner ring shell of the bearing. The moving component drives the push block to move to one side and abut against the inner ring of the inner ring shell, so that the inner ring shell moves to the inner ring surface of the outer ring shell and abuts against it. At this time, a crescent-shaped installation space is formed between the outer ring shell and the inner ring shell. The arc-shaped component moves vertically on the bottom surface of the clamping cavity. The outer and inner ring shells are fitted onto the top of the arc-shaped component. The top of the arc-shaped component is directly opposite the lower port of the discharge component. When the moving component is driven, the arc-shaped component moves vertically upward and extends into the clamping cavity. Its top is used to guide the rolling balls discharged by the discharge component.
[0010] The top of the arc-shaped component has a guide surface for guiding the steel ball, which extends to both sides of the crescent-shaped mounting space.
[0011] A placement plate is fixed between the clamping cavity and the driving cavity. The placement plate has a circular arc slide and a square slide in the horizontal direction. The positions of the circular arc slide and the square slide are combined in a T-shape. The bearing is placed at the upper end of the circular arc slide and the square slide. The circular arc slide slides in a sliding fit with the circular arc part, and the square slide slides in a sliding fit with the upper part of the push block.
[0012] Both sides of the upper part of the push block are fixedly connected with abutting blocks by screws, and the abutting blocks abut against the inner ring surface of the inner ring shell.
[0013] The moving component includes a first hydraulic cylinder fixedly connected to the inner wall of the drive chamber. The output end of the first hydraulic cylinder is fixedly connected to a drive plate. A first abutting surface is formed on one side of the top surface of the drive plate, and the other side of the top surface of the drive plate is fixed to the bottom surface of the push block.
[0014] The lower end face of the arc-shaped part has a second contact surface, which abuts against the first contact surface. Spring bodies are fixedly connected to both sides of the lower end face of the arc-shaped part. Two L-shaped plates are fixedly connected to the lower ends of the two spring bodies, and the two L-shaped plates are fixed to the lower surface of the placement plate.
[0015] The discharge assembly includes a conveying pipe, an adjusting pipe, and a fixing component. The conveying pipe is located above the bearing; the adjusting pipe is vertically slidingly fitted to the lower end of the conveying pipe, and the conveying pipe and the adjusting pipe communicate internally to form a conveying space; the fixing component has its upper inner end engaged with the lower end of the conveying pipe, and its lower inner end engaged with the upper end of the adjusting pipe. The lower end of the conveying pipe has telescopic plates at equal angles along a ring. Multiple telescopic plates have first threaded grooves on their outer sides. The conveying pipe has a first conveying hole inside. The regulating pipe has a second conveying hole inside. The upper part of the second conveying hole has a first thread. The regulating pipe has telescopic sliding openings at equal angles along a ring. The fixing component has a through hole inside. The upper part of the through hole has a second thread. The lower outer side of the fixing component has a second threaded groove. The lower end of the second conveying hole has an annular hole. A soft ring made of rubber is fitted inside the annular hole. A feeding pipe is fixed to the upper outer side of the conveying pipe. The lower end of the regulating pipe is directly above the bearing.
[0016] The telescopic plate slides within the telescopic sliding opening, and the through hole is fitted inside the lower end of the conveying pipe. The lower outer side of the fixing part is located inside the upper port of the adjusting pipe. The first thread engages with the second thread groove, and the second thread engages with the first thread groove.
[0017] A method for using an automated assembly equipment for bearing processing, the specific steps of which are as follows: S1. Loading: The workers place the inner and outer ring shells to be assembled on the upper surface of the placement plate, aligning the gap between the inner and outer ring shells with the arc-shaped sliding port, and fitting the bottom of the inner ring shell against the upper port of the square sliding port. Then, the outer ring of the bearing is firmly clamped by the clamping device. Subsequently, the shifting device is activated to rotate the bearing 180°, so that the gap between the inner and outer ring shells and the top of the arc-shaped part are aligned with the lower port of the adjusting tube, thus completing the pre-assembly alignment. S2. Spreading and Shaping: After the bearing is aligned, the first hydraulic cylinder is started to drive the drive plate to move horizontally, so that the push arc part moves vertically upward along the arc slide. At the same time, the drive plate drives the push block to slide along the square slide. The pressing strip at the top of the push block fits against the inner ring surface of the bearing inner ring shell and pushes it outward to form a regular crescent-shaped assembly gap between the inner ring shell and the outer ring shell. S3. Equipment fine-tuning: Adjust the distance between the discharge port and the bearing assembly position according to the thickness of the bearing and the number of steel balls assembled, and adjust the overlap length of the conveying pipe and the regulating pipe. Rotate to loosen the fixing part, and adjust the overlap length of the conveying pipe and the adjusting pipe by sliding the telescopic plate and the telescopic slide to change the volume of the conveying space to match the number of steel balls assembled. After adjustment, lock the fixing part. S4. Quantitative feeding: After the number of steel balls to be assembled is locked, the steel balls are fed into the conveying space composed of the conveying pipe and the regulating pipe according to the number of steel balls required for bearing assembly. This completes the quantitative storage and realizes the quantity of steel balls stored at one time to meet the bearing assembly requirements, providing material guarantee for one-time overall ball loading. S5. First Push Assembly: After quantitative material storage is completed, the second hydraulic cylinder is activated to drive the push rod downwards rapidly, penetrating through the first and second conveying holes, pushing the stored steel balls in the conveying space downwards as a whole. The steel balls fall after squeezing and expanding the soft ring; S6. Guiding: During the fall of the steel ball, it contacts the guide surface at the top of the arc-shaped part. The arc-shaped structure diverts the steel ball in both directions, and guides the steel ball evenly into the crescent-shaped assembly space pre-formed in the bearing. S7. Second Push Assembly: After the steel ball has completely entered the gap between the inner and outer rings of the bearing, the second hydraulic cylinder pushes in the opposite direction, the arc part is no longer supported by force, and automatically retracts downward along the arc slide and falls back into the arc slide, completing the automatic relocation and completely avoiding the steel ball assembly area. S8. Finishing the assembly: After the bearing assembly is completed, reset all equipment components, remove the finished bearing, and complete the entire assembly operation. Then, proceed to the next process.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a moving component to drive a circular arc-shaped component to vertically lift and lower, thereby limiting the inner ring of the bearing. A driving pusher horizontally pushes and expands the gap between the inner and outer ring shells, forming a crescent shape. The lifting component adjusts the overall height of the steel ball pushing device, and the conveying pipe and adjusting pipe are telescopic, changing the internal steel ball conveying and accommodating different quantities of steel balls. A fixing component locks the telescopic structure in place. Finally, the pushing device pushes all the steel balls in the conveying space in one batch. With the guiding effect of the circular arc-shaped component, the steel balls are precisely guided into the bearing installation gap, completing batch assembly. This allows for matching the number of steel balls required for different bearings, achieving a stable and uniform one-time push and distribution of quantitative steel balls, improving the steel ball placement speed and assembly regularity. It effectively solves many assembly drawbacks of traditional equipment and meets the needs of efficient and high-precision batch bearing assembly production.
[0019] This invention completely avoids interference between the arc component and the steel ball during installation and forming by extending and retracting the arc component, eliminating assembly jamming and misalignment problems. At the same time, it effectively prevents the steel ball from being pushed outward and falling off due to the impact force, greatly reducing the assembly defect rate and improving the stability of the finished product assembly.
[0020] This invention achieves telescopic adjustment through the sliding cooperation of a telescopic sliding plate and a telescopic sliding port. The equipment uses the connection position between the feeding pipe and the conveying pipe as the upper reference and the bottom port of the adjusting pipe as the lower reference. The vertical distance between the two points constitutes the effective length of the conveying space. The telescopic adjustment process can change this effective length, thereby adjusting the volume of the conveying space connecting the first and second conveying holes. The fixing component locks the relative positions of the conveying pipe and the adjusting pipe through internal and external bidirectional thread engagement. This allows for flexible adjustment of the storage space size according to the required number of steel balls for different bearing models, achieving quantitative storage and adapting to the assembly of multiple bearing specifications, making the equipment highly versatile. The threaded locking structure ensures dimensional stability after telescopic adjustment, preventing loosening or displacement. The soft ring can buffer the impact force of the steel balls during discharge, preventing the steel balls from being bumped, broken, or scratched, thus improving the quality of the finished product.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] like Figure 1 , Figure 2 , Figure 4 , Figure 10 , Figure 11 , Figure 16 As shown, the present invention provides an automatic assembly device for bearing processing, including... The workbench 1 has a shifting device 11 on its upper surface, and an assembly table 12 on its upper surface. The assembly table 12 has a clamping cavity 121 and a driving cavity 122 inside. The clamping cavity 121 has a clamping device 13 for fixing the bearing 2. A discharge component 4 is vertically positioned above the gap between the outer ring shell 21 and the inner ring shell 22. A lifting assembly 40 is located on the outer side of the upper part of the discharge component 4, and a pushing device 5 for pushing the rolling ball downwards is located at the top of the discharge component 4. A moving assembly 3 is located inside the driving cavity 122. A pusher block 32 slides horizontally and extends along the bottom surface of the clamping cavity 121. 2. The inner ring shell is inserted into the bearing 2. The moving component 3 drives the push block 32 to move to one side and abut against the inner ring of the inner ring shell 22, so that the inner ring shell 22 moves to the inner ring surface of the outer ring shell 21 and abuts against it. At this time, a crescent-shaped installation space 23 is formed between the outer ring shell 21 and the inner ring shell 22. The arc part 31 moves vertically in the installation space 23. The outer ring shell 21 and the inner ring shell 22 are fitted on the top of the arc part 31. The top of the arc part 31 is directly opposite the lower port of the discharge part 4. When the moving component 3 is driven, the arc part 31 moves vertically upward and extends into the clamping cavity 121. Its top is used to guide the rolling balls discharged by the discharge part 4.
[0025] The above scheme is adopted as follows: the moving component 3 drives the arc component 31 to rise and fall vertically, while the pusher 32 moves to one side to abut against the inner ring of the inner ring shell 22, so that the inner ring shell 22 moves to the inner ring surface of the outer ring shell 21 and abuts against it. At this time, a crescent-shaped installation space 23 is formed between the outer ring shell 21 and the inner ring shell 22. The lifting component 40 can adjust the overall height of the steel ball pushing device, and the conveying pipe 41 and the adjusting pipe 42 can be extended and adjusted to change the internal steel ball conveying and accommodating different numbers of steel balls. The fixing component 43 realizes the locking and fixing of the telescopic structure. Finally, the pushing device 5 pushes all the steel balls in the conveying space in batches at one time. With the guiding effect of the arc component 31, the steel balls are guided into the installation gap of the bearing 2 to complete the batch assembly. By combining the adjustable steel ball conveying space structure with the arc-shaped diversion guide structure, the number of steel balls assembled for different bearings 2 can be matched, realizing a one-time stable push and uniform diversion of quantitative steel balls, improving the steel ball insertion speed and assembly regularity, effectively solving many assembly drawbacks of traditional equipment, and adapting to the needs of efficient and high-precision batch bearing 2 assembly production.
[0026] like Figure 10 As shown, the top of the arc-shaped component 31 has a guide surface 311 for guiding the steel ball, and the guide surface 311 extends to both sides of the crescent-shaped mounting space 23.
[0027] The above solution allows the guide surface 311 to divert and guide multiple falling steel balls to both sides of the installation space 23, preventing them from piling up. After the steel balls have fully entered the crescent-shaped installation space 23 formed between the outer ring shell 21 and the inner ring shell 22, the arc-shaped component 31 retracts downwards and falls into the arc-shaped sliding opening 1231, automatically making way and avoiding the steel ball assembly area. This effectively solves the problems of steel ball accumulation and landing point deviation, achieving uniform distribution of multiple steel balls. Through the extension and retraction of the arc-shaped component 31, interference with the steel ball installation and forming is completely avoided, eliminating assembly jamming and squeezing misalignment problems. At the same time, it effectively prevents the steel balls from being pushed outwards and falling off due to the impact force, significantly reducing the assembly defect rate and improving the stability of the finished product assembly.
[0028] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a placement plate 123 is fixed between the clamping cavity 121 and the driving cavity 122. The placement plate 123 has a circular arc slide 1231 and a square slide 1232 in a horizontal direction inside. The positions of the circular arc slide 1231 and the square slide 1232 are combined in a T-shape. The bearing 2 is placed at the upper end of the circular arc slide 1231 and the square slide 1232. The circular arc slide 1231 is slidably fitted to the circular arc part 31, and the square slide 1232 is slidably fitted to the upper part of the push block 32.
[0029] The above scheme is adopted: the internal combination of the placement plate 123 forms a T-shaped arc-shaped sliding opening 1231 and a square sliding opening 1232, which respectively correspond to the sliding trajectory of the arc component 31 and the push block 32, and radially limit the two moving parts to ensure the motion accuracy of the arc component 31 vertically lifting and the push block 32 horizontally sliding. At the same time, the upper ports of the arc-shaped sliding opening 1231 and the square sliding opening 1232 can stably support the outer ring shell 21 and the inner ring shell 22.
[0030] like Figure 11 As shown, both sides of the upper part of the push block 32 are fixedly connected with abutting strips 321 by screws, and the abutting strips 321 abut against the inner ring surface of the inner ring shell 22.
[0031] The above scheme employs a method where two sets of abutment blocks 321 are fixed to the upper part of the push block 32 with screws. During operation, the abutment blocks 321 directly adhere to the inner ring surface of the inner ring shell 22, increasing the contact area. The horizontal jacking force stabilizes and supports the inner ring shell 22, causing it to deform and shift uniformly, forming a regular crescent-shaped gap with the outer ring shell 21. Compared to single-point jacking, the strip-shaped abutment structure distributes force more evenly, preventing localized compression deformation and damage to the inner ring shell 22. It also improves the stability of the inner ring opening, ensuring a regular gap between the outer ring shell 21 and the inner ring shell 22, providing standard space for steel ball assembly, and reducing the scrap rate of bearing 2 assembly.
[0032] like Figure 4 , Figure 8 As shown, the moving component 3 includes a first hydraulic cylinder 301 fixedly connected to the inner wall of the drive cavity 122. The output end of the first hydraulic cylinder 301 is fixedly connected to a drive plate 302. A first contact surface 3021 is formed on one side of the top surface of the drive plate 302, and the other side of the top surface of the drive plate 302 is fixed to the bottom surface of the push block 32.
[0033] The above scheme is adopted: the first hydraulic cylinder 301 drives the drive plate 302 to move horizontally, and the first contact surface 3021 presses the second contact surface 312 at the lower end of the arc part 31, pushing the arc part 31 to extend vertically upward along the arc slide 1231. At the same time, the drive plate 302 drives the push block 32 to slide horizontally along the square slide 1232, so that the pressing strip 321 on the upper part of the push block 32 tightly abuts against the inner ring surface of the inner ring shell 22, and continuously pushes the inner ring shell 22 outward, so that the outer ring shell 21 and the inner ring shell 22 form a regular crescent-shaped installation space 23.
[0034] like Figure 5 , Figure 8As shown, a second contact surface 312 is formed on the lower end face of the arc-shaped part 31. The second contact surface 312 abuts against the first contact surface 3021. Spring bodies 303 are fixedly connected to both sides of the lower end face of the arc-shaped part 31. Two L-shaped plates 304 are fixedly connected to the lower ends of the two spring bodies 303 respectively. The two L-shaped plates 304 are fixed to the lower surface of the placement plate 123.
[0035] Using the above scheme: the arc-shaped part 31 extends upward under force by fitting the lower second contact surface 312 with the first contact surface 3021 of the drive plate 302, completing the steel ball guiding operation. After the steel ball is fully assembled and inserted into the crescent-shaped installation space 23, the first hydraulic cylinder 301 resets, and the elastic recoil force of the two spring bodies 303 pulls the arc-shaped part 31 downward to automatically retract and reset, completely retracting into the arc-shaped sliding opening 1231. The L-shaped plate 304 provides fixed support for the spring body 303, ensuring the stability of the elastic telescopic reset action.
[0036] like Figure 2 , Figure 3 , Figure 14 , Figure 15 As shown, the lower end of the conveying pipe 41 is provided with a telescopic plate 411 at an equal angle along the ring. The outer side of the multiple telescopic plates 411 is provided with a first threaded groove 412. The conveying pipe 41 is provided with a first conveying hole 413. The adjusting pipe 42 is provided with a second conveying hole 421. The upper part of the second conveying hole 421 is provided with a first thread 422. The adjusting pipe 42 is provided with a telescopic sliding mouth 423 at an equal angle along the ring. The fixing member 43 is provided with a through hole 431. The upper part of the through hole 431 is provided with a second thread 432. The lower outer side of the fixing member 43 is provided with a second threaded groove 433. The lower end of the second conveying hole 421 is provided with an annular hole 4211. A soft ring 424 is sleeved inside the annular hole 4211. The soft ring 424 is made of rubber. The upper outer side of the conveying pipe 41 is connected to and fixed with a feeding pipe 414.
[0037] The above scheme is adopted: the conveying pipe 41 slides with the telescopic sliding port 423 of the regulating pipe 42 through the annularly distributed telescopic plates 411, thereby realizing telescopic adjustment. The equipment takes the position where the feeding pipe 414 and the conveying pipe 41 communicate as the upper reference and the bottom port of the regulating pipe 42 as the lower reference. The vertical distance between the two points constitutes the effective length of the conveying space. The telescopic adjustment process can change this effective length, thereby adjusting the volume of the conveying space connected by the first conveying hole 413 and the second conveying hole 421. The fixing member 43 locks the conveying pipe 41 and the regulating pipe 42 through internal and external bidirectional thread engagement. The relative position of pipe 42; a soft ring 424 is embedded in the annular hole 4211 at the lower end of the regulating pipe 42. Steel balls are fed into the conveying channel by the feeding pipe 414 and continuously discharged from the lower end of the regulating pipe 42. This allows for flexible adjustment of the storage space according to the assembly quantity requirements of steel balls for different models of bearings 2, quantitative storage, and compatibility with the assembly of bearings 2 of multiple specifications. The equipment has strong versatility. The threaded locking structure ensures that the dimensions are stable after the expansion and contraction are adjusted, without loosening or deviation. The soft ring 424 can buffer the impact force of the discharged steel balls, avoid the steel balls from being bumped and broken, and prevent scratches, thus improving the quality of the finished product.
[0038] like Figure 14 As shown, the telescopic plate 411 is slidably fitted inside the telescopic sliding port 423, the through hole 431 is sleeved inside the lower end of the conveying pipe 41, the lower outer side of the fixing member 43 is located inside the upper port of the adjusting pipe 42, the first thread 422 is engaged with the second thread groove 433, and the second thread 432 is engaged with the first thread groove 412.
[0039] The above solution involves a telescopic plate 411 that slides within the telescopic sliding opening 423, enabling directional telescopic movement of the conveying pipe 41 and the adjusting pipe 42, thus preventing circumferential offset. A fixing component 43 is fitted onto the lower end of the conveying pipe 41, with the upper second thread 432 engaging the first thread groove 412 of the conveying pipe 41, and the lower first thread 422 engaging the second thread groove 433 of the adjusting pipe 42, forming a bidirectional threaded locking structure. This ensures precise orientation during telescopic adjustment, preventing offset and jamming. The bidirectional threaded locking structure provides high locking strength, preventing changes in the conveying space dimensions due to vibration during operation, ensuring consistent and accurate steel ball delivery each time, eliminating overloading or underloading issues, and improving product assembly consistency.
[0040] like Figure 12 , Figure 13As shown, the lifting assembly 40 includes a motor 401 fixedly connected to the inner wall of the support frame on the workbench 1. A gear 402 is sleeved on the output end of the motor 401. The gear 402 meshes with a rack 403. A fixing plate 404 is fixedly connected to the side of the rack 403. One side of the fixing plate 404 is fixedly connected to the upper end of the conveying pipe 41. Fixing rods 405 are fixedly connected to the upper surfaces of both sides of the fixing plate 404. A support plate 406 is fixedly connected to the upper surface of the fixing rods 405. Slider blocks 407 are fixed to both sides of the support plate 406. The sliders 407 slide on the sliding groove plates 408 on both sides of the middle of the support frame.
[0041] The above solution involves a motor 401 driving a gear 402 to rotate, which meshes with a rack 403 to achieve linear transmission, thereby vertically raising and lowering the fixed plate 404, the upper conveying pipe 41, and the pushing device 5. The fixed plate 404 is connected to a support plate 406 via a fixed rod 405, and a slider 407 slides against a chute plate 408 to limit and guide the lifting motion. This facilitates height adjustment of the steel ball conveying and pushing mechanism, allows for the adaptation of bearings 2 of different thicknesses and specifications, and ensures optimal spacing between the discharge port and the assembly position.
[0042] like Figure 2 , Figure 12 , Figure 15 As shown, the pushing device 5 includes a second hydraulic cylinder 51 fixed at the middle of the upper surface of the support plate 406. The output end of the second hydraulic cylinder 51 is fixedly connected to a push rod 52. The lower end of the push rod 52 is slidably fitted inside the conveying pipe 41. During operation, the push rod 52 extends downwards sequentially into the interior of the first conveying hole 413 and the second conveying hole 421. The bottom end of the push rod 52 is formed into a cone shape.
[0043] The above solution involves using a second hydraulic cylinder 51 to drive a push rod 52 to move downwards quickly. The conical bottom end of the push rod adapts to the conveying channel structure, smoothly passing through the entire conveying space and pushing multiple steel balls stored inside downwards at once to complete batch feeding. After the push rod 52 resets, the next round of material storage can begin. This solution helps to change the inefficient mode of pushing single steel balls in the traditional way, enabling multiple steel balls to be pushed and assembled simultaneously at one time, greatly improving the efficiency of bearing 2 assembly and adapting to mass industrial production.
[0044] A method for using an automated assembly equipment for bearing processing, the specific steps of which are as follows: S1. Loading: The workers place the inner ring shell 22 and outer ring shell 21 to be assembled on the upper surface of the placement plate 123, aligning the gap between the inner ring shell 22 and the outer ring shell 21 with the port of the arc-shaped sliding opening 1231, and the bottom of the inner ring shell 22 is attached to the upper port of the square sliding opening 1232. Then, the outer ring of the bearing 2 is firmly clamped by the clamping device 13. Subsequently, the shifting device 11 is activated to rotate the bearing 2 180°, so that the gap between the inner ring shell 22 and the outer ring shell 21 and the top of the arc-shaped part 31 are aligned with the lower port of the adjusting tube 42, thus completing the pre-assembly alignment. S2. Spreading and Shaping: After the bearing 2 is aligned, the first hydraulic cylinder 301 is activated to drive the drive plate 302 to move horizontally, so that the push arc part 31 moves vertically upward along the arc slide 1231. At the same time, the drive plate 302 drives the push block 32 to slide along the square slide 1232. The pressing strip 321 at the top of the push block 32 fits against the inner ring surface 22 of the inner ring shell 22 of the bearing 2 and pushes it outward, so that the inner ring shell 22 and the outer ring shell 21 form a regular crescent-shaped assembly gap. Compared with single-point pushing, the strip pressing structure is more uniformly stressed, which can avoid local compression deformation and damage of the inner ring shell 22. At the same time, it improves the stability of the inner ring spreading and ensures that the gap between the outer ring shell 21 and the inner ring shell 22 is formed regularly, providing standard space for steel ball assembly. S3. Equipment fine-tuning: Adjust the distance between the discharge port and the assembly position of bearing 2 according to the thickness of bearing 2 and the number of steel balls assembled, and adjust the overlap length of conveying pipe 41 and adjusting pipe 42. Rotate to loosen the fixing part 43, and adjust the overlap length of the conveying pipe 41 and the adjusting pipe 42 through the sliding cooperation of the telescopic plate 411 and the telescopic slide 423 to change the volume of the conveying space to adapt to the number of steel balls assembled. After the adjustment is completed, lock the fixing part 43. The size of the storage space can be flexibly adjusted according to the number of steel balls assembled in different models of bearings 2, and the material can be stored quantitatively. It is suitable for the assembly of bearings 2 of multiple specifications and has strong versatility. S4. Quantitative feeding: After the number of steel balls to be assembled is locked, the steel balls are fed into the conveying space composed of the conveying pipe 41 and the regulating pipe 42 through the feeding pipe 414 according to the number of steel balls required for the assembly of bearing 2. This completes the quantitative storage and ensures that the number of steel balls stored at one time matches the assembly requirements of bearing 2. This provides material support for the one-time overall ball loading, ensures accurate orientation during the telescopic adjustment process, and prevents deviation or jamming. The bidirectional threaded locking structure has high locking strength and will not cause changes in the size of the conveying space due to vibration during operation. This ensures that the number of steel balls pushed each time is accurate and consistent, eliminates the problem of overloading or underloading, and improves the consistency of product assembly. S5. First Push Assembly: After quantitative material storage is completed, the second hydraulic cylinder 51 is activated to drive the push rod 52 downwards rapidly, passing through the first conveying hole 413 and the second conveying hole 421, pushing the stored steel balls in the conveying space downwards as a whole. The steel balls fall after squeezing and expanding the soft ring 424. The soft ring 424 can buffer the impact force of the steel balls when they are discharged, preventing the steel balls from being bumped, broken, or scratched, thus improving the quality of the finished product. S6. Guiding: During the falling process, the steel ball contacts the guide surface 311 at the top of the arc part 31. The arc structure diverts the steel ball in both directions and guides the steel ball into the crescent-shaped assembly space pre-formed in the bearing 2 evenly. This helps to solve the problems of steel ball accumulation and landing point deviation, and realizes the even distribution of multiple steel balls. S7. Second Push Assembly: After the steel ball has fully entered the gap between the inner and outer rings of bearing 2, the second hydraulic cylinder 51 pushes in the opposite direction. The arc-shaped part 31 is no longer supported by force and automatically retracts downward along the arc-shaped sliding opening 1231, falling back into the arc-shaped sliding opening 1231, completing the automatic repositioning and completely avoiding the steel ball assembly area. This completely avoids the arc-shaped part 31 interfering with the steel ball installation and forming, eliminates assembly jamming and squeezing misalignment problems, and effectively prevents the steel ball from jumping outward and falling off due to the pushing impact force, greatly reducing the assembly defect rate and improving the stability of the finished product assembly. S8. Finishing the assembly: After bearing 2 is assembled, reset all equipment components, remove the finished bearing 2, and complete the entire assembly operation. Then you can proceed to the next process.
[0045] Working principle and usage process of this invention: First, the workers place the outer ring shell 21 and inner ring shell 22 to be assembled on the upper surface of the placement plate 123. The gap between the outer ring shells 21 covers the port of the arc-shaped sliding opening 1231, and the bottom of the inner ring shell 22 abuts against the upper port of the square sliding opening 1232. Then, the clamping device 13 clamps and fixes the outer ring shell 21. After the outer ring shell 21 is clamped and fixed, the shifting device 11 is activated to rotate the clamped outer ring shell 21 and inner ring shell 22 180 degrees, so that the gap between the outer ring shell 21 and inner ring shell 22 is rotated to the lower port of the adjusting tube 42. The gap between the outer ring shell 21 and inner ring shell 22 is directly opposite the lower port of the adjusting tube 42, and the top of the arc-shaped component 31... At the lower end of the regulating tube 42, the steel ball is installed. First, the first hydraulic cylinder 301 on the moving assembly 3 is activated to drive the drive plate 302 to move horizontally. The first contact surface 3021 presses the second contact surface 312 at the lower end of the arc part 31, pushing the arc part 31 to extend vertically upward along the arc slide 1231. At the same time, the drive plate 302 drives the push block 32 to slide horizontally along the square slide 1232, so that the pressing strip 321 on the upper part of the push block 32 tightly abuts against the inner ring surface of the inner ring shell 22, and continuously pushes the inner ring shell 22 outward, so that a regular crescent-shaped installation space 23 is formed between the outer ring shell 21 and the inner ring shell 22, providing a standard installation area for subsequent steel ball assembly.
[0046] After a crescent-shaped installation space 23 is formed between the inner and outer rings of the bearing 2, the lifting assembly 40 is activated. The motor 401 drives the gear 402 to mesh with the rack 403, which in turn drives the fixed plate 404, the conveying pipe 41, and the adjusting pipe 42 to rise and fall vertically as a whole. The distance between the lower end of the conveying pipe 41 and the adjusting pipe 42 and the assembly position of the bearing 2 is adjusted according to the thickness of the bearing 2.
[0047] Workers can rotate the fixing part 43 in advance to release the locking state of the conveying pipe 41 and the adjusting pipe 42 according to the required number of steel balls to be assembled in the bearing 2 to be assembled. The overlap length of the conveying pipe 41 and the adjusting pipe 42 can be adjusted by the sliding cooperation of the telescopic plate 411 and the telescopic slide 423.
[0048] In this equipment, the effective length of the conveying space is defined as the vertical distance from the point where the feeding pipe 414 connects to the conveying pipe 41 to the bottom port of the adjusting pipe 42. This effective length can be changed by telescopic adjustment, thereby changing the volume of the conveying space to adapt to the storage and assembly requirements of different numbers of steel balls. After adjustment, tighten the fixing part 43 again to lock the telescopic structure through the engagement of internal and external threads, ensuring the stability of the conveying space dimensions. At the same time, the soft ring 424 at the lower end of the adjusting pipe 42 can prevent the steel balls from being discharged.
[0049] Steel balls are fed into the conveying space connected to the conveying pipe 41 and the regulating pipe 42 through the feeding pipe 414 to complete quantitative storage. Then, the pushing device 5 activates the second hydraulic cylinder 51 to drive the push rod 52 to move downwards in a straight line. It smoothly passes through the first conveying hole 413 and the second conveying hole 421, pushing the multiple steel balls stored in the conveying space downwards at once. The steel balls will squeeze and expand the interior of the soft ring 424 in sequence and fall downwards, avoiding scratches on the outer surface of the steel balls caused by traditional claws. Multiple steel balls fall from the lower end of the regulating pipe 42 in sequence. During the fall, they come into contact with the top guide surface 311 of the arc part 31. The arc structure of the guide surface 311 diverts and guides the scattered steel balls in both directions, diverting the multiple steel balls evenly to both sides and guiding them into the pre-formed crescent-shaped installation space 23, realizing the assembly of multiple steel balls and avoiding the accumulation phenomenon.
