Description

Technical Field

[0001] This utility model relates to the field of bearing pressing technology, and more specifically, to a pressing device for bearing production. Background Technology

[0002] In existing technologies, bearing pressing devices have certain technical defects, mainly in two key aspects. First, the bearing pressing process requires the cooperation of multiple components with guide holes or drop holes to unload the balls, and then other pressing components to complete the bearing pressing process. This traditional pressing device has serious problems in actual production applications. When it is necessary to install or disassemble these components with guide holes or drop holes, it is usually necessary to use professional tools such as wrenches and Allen wrenches for assistance. The entire disassembly and assembly process is cumbersome, complicated, and lengthy. Especially when the production line frequently switches between different specifications of bearing products, this disassembly and assembly method is time-consuming and labor-intensive, and cannot achieve convenient replacement of these components. In a mass production environment, this inefficient replacement method directly leads to extended equipment downtime, seriously affecting production cycle and efficiency, while also increasing the company's machine setup costs and manpower input.

[0003] Secondly, while some improved equipment has achieved convenient replacement of these material guiding components and pressing assemblies through the cooperation of some innovative parts, these designs still have obvious structural shortcomings. Although such devices reduce tool dependence and simplify the replacement process to a certain extent, their overall structure is simple, lacks multiple safety mechanisms, and has serious instability. Especially under complex working conditions such as high-speed production, vibration, or continuous stamping, the fixed structure is prone to loosening due to external forces such as mechanical impact and vibration accumulation, and may even fall off unexpectedly after long-term operation. This potential safety hazard not only threatens the normal operation of the equipment, but may also lead to ball misalignment, poor guidance, or even jamming, triggering a chain reaction of bearing pressing quality problems or equipment failures. In the bearing production process, this instability has become an important factor limiting the application range of pressing devices, ultimately resulting in a significant reduction in the practicality and reliability of pressing devices used in bearing production, seriously affecting their application and promotion in the field of high-end bearing manufacturing.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a pressing device for bearing production, which has the following advantages: 1. By setting a flexible combination structure of lifting seat, fixed seat and sliding plate on one side of the bracket, and with the detachable design of the fitting rod and fitting sleeve, the problem of cumbersome disassembly and assembly of bearing pressing devices in the prior art has been successfully solved. The device adopts an innovative tool-free operating system. By using the precise cooperation between the separating sleeve and the control board, the quick disassembly and assembly of components with guide holes and drop holes can be realized. In particular, through the coordinated work of the moving sleeve and the fitting groove, combined with the snap-fit ​​connection between the connecting frame and the connecting groove, operators can quickly complete the maintenance and replacement of the guide plate, pressing block and sliding plate without the need for professional tools such as wrenches and Allen wrenches. This efficient disassembly and assembly mechanism performs well when the production line frequently switches between different specifications of bearing products. Through the snap-fit ​​of the fixed rod and the fixed groove, not only is the replacement process simplified, but maintenance time is also greatly reduced. This effectively shortens the downtime of equipment in the mass production environment, significantly improves the production cycle and production efficiency, and at the same time reduces the company's machine adjustment costs and manpower input.

[0014] 2. The multi-locking protection mechanism effectively solves the technical problem of insufficient stability of existing fixed structures. Among them, the interlocking design of the fixing rod and the fixing groove, and the reliable connection between the support rod and the control plate together constitute a complete anti-loosening safety system. In particular, the limiting of the inner wall of the fastening sleeve against the outer wall of the fixing plate ensures the stability of the device after fixing. It effectively avoids the connection loosening or accidental detachment caused by external forces such as mechanical impact and vibration accumulation under complex working conditions such as high-speed production, vibration or continuous stamping. Through the cleverly designed fixing plate and fixing frame structure, the device forms a perfect self-locking function and anti-loosening mechanism. It can maintain structural stability even in the production environment of long-term operation. It will not cause the pressing system to fail due to slight displacement of the main fixing components. It avoids ball misalignment, poor guidance or even jamming caused by uncoordinated movement of components. It effectively eliminates safety hazards, protects the pressing system from damage, and ultimately improves the practicality and reliability of the pressing device for bearing production in high-precision and high-reliability applications, promoting its application in the field of high-end bearing manufacturing.

[0021] A slide rail 24 is detachably provided on one side of the bracket 1, and a slider 25 is slidably provided on the slide rail 24. The slider 25 is detachably installed on one side of the lifting seat 2. A lifting cylinder 26 is detachably provided on one side of the bracket 1, and the output end of the lifting cylinder 26 is connected to the lifting seat 2.

[0022] A push cylinder 27 is detachably mounted on the bracket 1. A connecting seat 28 is detachably mounted on the output end of the push cylinder 27. A guide plate 29 is detachably mounted on the lower side of the lifting seat 2. A pressing cylinder 30 is detachably mounted on the top of the lifting seat 2. A pressing frame 31 is connected to the output end of the pressing cylinder 30. A pressing block 32 is detachably mounted below the fixed seat 3. A guide hole 33 is opened on both the guide plate 29 and the sliding plate 4. A dropping hole 34 is opened in the fixed seat 3 and the pressing block 32. A pressing component 35 is provided below the pressing block 32. The pressing frame 31 is slidably connected to the fixed seat 3. In this embodiment, when the device is needed, the balls are first conveyed to the guide holes 33 on the guide plate 29 by an external conveying device. Then, the balls fall into the guide holes 33 on the sliding plate 4. The bearing sleeve is then placed on the top of the pressing assembly 35, and the pressing assembly 35 is opened, causing the pressing assembly 35 to push the bearing sleeve upward, so that the top of the bearing sleeve contacts the lower end face of the pressing block 32. Then, the pressing assembly 35 is closed, and the two side pushing cylinders 27 are opened simultaneously, so that the pushing cylinders 27 drive the sliding plate 4 to move through the connecting seat 28. The sliding plate 4 drives the balls to roll through the guide holes 33. When the guide holes 33 on the sliding plate 4 and the dropping holes 34 on the fixed seat 3 are concentric, the balls roll through the guide holes 33 on the fixed seat 3. The material falls from the drop hole 34 into the guide hole 33 in the pressing block 32. Then, the reverse drive cylinder 27 drives the connecting seat 28 and the sliding plate 4 to reset. Then, the pressing cylinder 30 is opened, causing the pressing cylinder 30 to drive the pressing frame 31 to press down. Then, the pressing frame 31 passes through the drop hole 34 on the fixed seat 3 and enters the drop hole 34 in the pressing block 32 until the ball is pressed into the bearing sleeve. Then, the reverse drive cylinder 30 is driven to reset the pressing frame 31 and the pressing assembly 35 is reverse driven to reset. Then, the pressing process can be performed again by following the above steps. When it is necessary to replace the part with the guide hole 33 and the drop hole 34, first drive the lifting cylinder 26 to rise, so that the lifting cylinder 26 drives the lifting seat 2 and the guide hole 34 to reset. The plate 29 and other components rise, and then the control plate 11 is rotated forward, causing the control hole 12 to rotate to a position concentric with the support rod 19. Then, the fastening sleeve 17 is pushed, causing the fastening sleeve 17 to gradually slide the support rod 19 connected to one side into the control hole 12. The fastening sleeve 17 and the control plate 11 cooperate to compress the support spring 39 sleeved on the outside of the support rod 19, so that the fastening sleeve 17 gradually stops limiting the outer wall of the fixing plate 16. Then, the separating sleeve 7 is rotated forward, causing multiple fixing brackets 14 on one side to rotate forward. Then, the fixing brackets 14 drive the fixing plate 16, the fixing rod 15 and the traction spring 40 to rotate forward. Then, the inner wall of the fixing groove 18 compresses one end of the fixing rod 15. Because one end of the fixing rod 15 and the... The rounded corner design at the inner edge of the fixing groove 18 allows one end of the fixing rod 15 to gradually slide out of the fixing groove 18, while the other end of the fixing rod 15 drives the fixing plate 16 to slide outward. This causes the fixing plate 16 to pull the traction spring 40 outward, and simultaneously the separating sleeve 7 drives the outer pressing block 8 to rotate clockwise. Due to the special structural design of the pressing block 8 and the force application block 10, when the pressing block 8 rotates clockwise, the spring spring 13 resets and pushes the moving sleeve 9, causing the moving sleeve 9 to gradually slide along the guide rail 38. The moving sleeve 9 also drives the force application block 10 to move, ensuring that one side of the force application block 10 is always in close contact with the pressing block 8. Then, the inner fitting groove 20 of the moving sleeve 9 gradually stops limiting the outer wall of the fitting block 21, and then multiple fitting springs 37 simultaneously reset and push the fitting block 21.This causes the bonding block 21 to move one side of the connecting frame 22 outwards. Then, one end of the connecting frame 22 gradually slides out of the connecting groove 23, and the fitting sleeve 6 is pulled to one side, thus separating the fitting sleeve 6 and the fitting rod 5. Then, following the same steps, the other fitting sleeves 6 and fitting rods 5 are separated. Finally, the guide plate 29, the pressing block 32, and the sliding plate 4 can be gradually removed and replaced.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: anti-slip strips 36 are provided on the outer sides of the control panel 11, the separation sleeve 7 and the fastening sleeve 17.

[0024] Multiple bonding springs 37 are connected to one side of the bonding block 21, and the other end of the bonding spring 37 is connected to the outer wall of the fitting sleeve 6.

[0025] A guide rail 38 is fixedly provided on the outer side of the fitting sleeve 6. The guide rail 38 is aligned with the fitting block 21 and is located in the fitting groove 20.

[0026] A support spring 39 is movably sleeved on the outside of the support rod 19. One end of the support spring 39 is connected to the fastening sleeve 17, and the other end of the support spring 39 abuts against one side of the control plate 11.

[0027] A traction spring 40 is movably sleeved on the outside of the fixed rod 15, and the two ends of the traction spring 40 are connected to the fixed plate 16 and the fixed frame 14 respectively.

[0028] More specifically, after the guide plate 29, pressing block 32, and sliding plate 4 are replaced, first install the guide plate 29, pressing block 32, and sliding plate 4 into their corresponding positions, ensuring that the corresponding fitting rods 5 pass through their corresponding mounting holes. Then, fit the fitting sleeve 6 onto the outside of the fitting rod 5 from the other side. Next, rotate the separating sleeve 7 in the opposite direction, causing the separating sleeve 7 to drive the fixing rod 15, fixing plate 16, and traction spring 40 to rotate in the opposite direction via the fixing bracket 14 on one side. At the same time, the separating sleeve 7 will drive the outer pressing block 8 to rotate in the opposite direction and reset. Then, the pressing block 8 will push the force application block 10 to one side, causing the force application block 10 to slide and reset. Then, the force application block 10... The moving sleeve 9 slides and resets along the guide rail 38, and the moving sleeve 9 also drives the inner fitting groove 20 to slide and reset. Due to the chamfer design of one side of the inner wall of the fitting groove 20 and one side of the outer wall of the fitting block 21, the inner wall of the fitting groove 20 gradually presses the fitting block 21 inward, causing the fitting block 21 to move inward and reset. The fitting block 21 will also compress one side of the fitting spring 37, causing the fitting block 21 to drive one side of the connecting bracket 22 to gradually engage in the connecting groove 23. At the same time, the moving sleeve 9 will compress the spring spring 13. When the separating sleeve 7 is fully reset, one end of the connecting bracket 22 is reinserted into the connecting groove 23, forming a locking relationship. At this time, the fixing bracket 1... 4. This causes the fixing rod 15 and other components to rotate to the position corresponding to the original fixing slot 18. Then, the traction spring 40 resets and pulls the fixing plate 16, causing the fixing plate 16 to slide one side of the fixing rod 15 inward. Then, one end of the fixing rod 15 will re-insert into the original fixing slot 18. Then, the fastening sleeve 17 is released, and the support spring 39 resets and pushes the fastening sleeve 17, causing the fastening sleeve 17 to slide and reset one side of the support rod 19. When the support spring 39 is fully reset, the support rod 19 moves back to the original side of the control plate 11, and the support rod 19 no longer passes through the control hole 12. Then, the control plate 11 is rotated in the opposite direction, causing the control plate 11 to drive the control hole 12. 2. Rotate and reset to a position not corresponding to the support rod 19. Then, the support rod 19 supports the fastening sleeve 17 to one side of the control plate 11, making the fastening sleeve 17 unable to slide easily. Then, the inner wall of the fastening sleeve 17 will limit the outer wall of the fixing plate 16 again, making the fixing plate 16 and the fixing rod 15 unable to slide outward. Then, the fixing rod 15 and the fixing groove 18 cooperate to form a rotation limit on the fixing frame 14, preventing the separation sleeve 7 from rotating accidentally, thereby achieving a convenient and stable connection. Then, follow the above steps to engage other fitting sleeves 6, thereby achieving convenient replacement of components with guide holes 33 and drop holes 34, and ensuring their installation stability.

[0029] In summary, during the use or operation of the overall equipment: When the equipment needs to be used, the balls are first conveyed to the guide holes 33 on the guide plate 29 by an external conveying device. Then, the balls fall into the guide holes 33 on the sliding plate 4. Next, the bearing sleeve is placed on the top of the pressing assembly 35, and the pressing assembly 35 is opened, causing the pressing assembly 35 to push the bearing sleeve upward, so that the top of the bearing sleeve contacts the lower end face of the pressing block 32. Then, the pressing assembly 35 is closed, and then the two side pushing cylinders 27 are opened simultaneously, so that the pushing cylinders 27 drive the sliding plate 4 to move through the connecting seat 28. The sliding plate 4 drives the balls to roll through the guide holes 33. When the guide holes 33 on the sliding plate 4 and the dropping holes 34 on the fixed seat 3 are concentric, the balls roll through the fixed seat 3. The material falling through the drop hole 34 on the base 3 falls into the guide hole 33 in the pressing block 32. Then, the reverse drive cylinder 27 drives the connecting base 28 and the sliding plate 4 to reset. Then, the pressing cylinder 30 is opened, causing the pressing cylinder 30 to drive the pressing frame 31 to press down. The pressing frame 31 then passes through the drop hole 34 on the fixed base 3 and enters the drop hole 34 in the pressing block 32 until the ball is pressed into the bearing sleeve. Then, the reverse drive cylinder 30 is driven, causing the pressing frame 31 to reset and the pressing assembly 35 to be reverse driven to reset. Then, the pressing process can be performed again by following the above steps. When it is necessary to replace the part with the guide hole 33 and the drop hole 34, first drive the lifting cylinder 26 to rise, causing the lifting cylinder 26 to drive the lifting base. Components such as guide plate 29 rise, and then control plate 11 is rotated forward, causing control hole 12 to rotate to a position concentric with support rod 19. Then, fastening sleeve 17 is pushed, causing support rod 19 connected to one side to gradually slide into control hole 12. Fastening sleeve 17 and control plate 11 cooperate to compress support spring 39 sleeved on the outside of support rod 19, so that fastening sleeve 17 gradually stops limiting the outer wall of fixing plate 16. Then, separation sleeve 7 is rotated forward, causing multiple fixing brackets 14 on one side to rotate forward. Then, fixing brackets 14 cause fixing plate 16, fixing rod 15 and traction spring 40 to rotate forward. Then, the inner wall of fixing groove 18 compresses one end of fixing rod 15. The rounded corner design at the inner edge of the fixing groove 18 allows one end of the fixing rod 15 to gradually slide out of the fixing groove 18, while the other end of the fixing rod 15 drives the fixing plate 16 to slide outward. This causes the fixing plate 16 to pull the traction spring 40 outward, and at the same time, the separating sleeve 7 drives the outer pressing block 8 to rotate forward. Due to the special structural design of the pressing block 8 and the force application block 10, when the pressing block 8 rotates forward, the spring spring 13 resets and pushes the moving sleeve 9, causing the moving sleeve 9 to gradually slide along the guide rail 38. The moving sleeve 9 also drives the force application block 10 to move, ensuring that one side of the force application block 10 is always in close contact with the pressing block 8. Then, the inner fitting groove 20 of the moving sleeve 9 gradually stops limiting the outer wall of the fitting block 21, and then multiple fitting springs 37 simultaneously reset and push the fitting block 21.This causes the bonding block 21 to move one side of the connecting frame 22 outwards. Then, one end of the connecting frame 22 gradually slides out of the connecting groove 23, and the fitting sleeve 6 is pulled to one side, thus separating the fitting sleeve 6 and the fitting rod 5. Then, following the same steps, the other fitting sleeves 6 and fitting rods 5 are separated. Finally, the guide plate 29, the pressing block 32, and the sliding plate 4 can be gradually removed and replaced.

[0030] After the guide plate 29, pressing block 32, and sliding plate 4 are replaced, first install the guide plate 29, pressing block 32, and sliding plate 4 into their corresponding positions, ensuring that the corresponding fitting rods 5 pass through their corresponding mounting holes. Then, fit the fitting sleeve 6 onto the outside of the fitting rod 5 from the other side. Next, rotate the separating sleeve 7 in the opposite direction, causing the separating sleeve 7 to drive the fixing rod 15, fixing plate 16, and traction spring 40 to rotate in the opposite direction via the fixing bracket 14 on one side. At the same time, the separating sleeve 7 will drive the outer pressing block 8 to rotate in the opposite direction and reset. Then, the pressing block 8 will push the force application block 10 to one side, causing the force application block 10 to slide and reset. Then, the force application block 10 will drive the movement. The sleeve 9 slides and resets along the guide rail 38, and the moving sleeve 9 will drive the inner fitting groove 20 to slide and reset. Due to the chamfer design of one side of the inner wall of the fitting groove 20 and one side of the outer wall of the fitting block 21, the inner wall of the fitting groove 20 gradually presses the fitting block 21 inward, causing the fitting block 21 to move inward and reset. The fitting block 21 will also compress one side of the fitting spring 37, causing the fitting block 21 to drive one side of the connecting bracket 22 to gradually engage in the connecting groove 23. At the same time, the moving sleeve 9 will compress the spring spring 13. When the separating sleeve 7 is fully reset, one end of the connecting bracket 22 is reinserted into the connecting groove 23, forming a locking relationship. At this time, the fixing bracket 14 is just right. The fixed rod 15 and other components are rotated to the position corresponding to the original fixed groove 18. Then, the traction spring 40 returns to its original position and pulls the fixed plate 16, causing the fixed plate 16 to slide one side of the fixed rod 15 inward. Then, one end of the fixed rod 15 will be reinserted into the original fixed groove 18. Then, the fastening sleeve 17 is released, and the support spring 39 returns to its original position and pushes the fastening sleeve 17, causing the fastening sleeve 17 to slide and return one side of the support rod 19. When the support spring 39 has fully returned to its original position, the support rod 19 moves back to the original side of the control plate 11, and the support rod 19 no longer passes through the control hole 12. Then, the control plate 11 is rotated in the opposite direction, causing the control plate 11 to rotate the control hole 12. The device is reset to a position not corresponding to the support rod 19. Then, the support rod 19 supports the fastening sleeve 17 to one side of the control plate 11, making the fastening sleeve 17 unable to slide easily. Then, the inner wall of the fastening sleeve 17 will limit the outer wall of the fixing plate 16 again, making the fixing plate 16 and the fixing rod 15 unable to slide outward. Then, the fixing rod 15 and the fixing groove 18 cooperate to form a rotation limit on the fixing frame 14, preventing the separation sleeve 7 from rotating accidentally, thereby achieving a convenient and stable connection. Then, the other fitting sleeves 6 are engaged according to the above steps, thereby realizing the convenient replacement of the parts with the guide hole 33 and the drop hole 34, and ensuring their installation stability.
