Description

Technical Field

[0001] This utility model relates to the technical field of bearing press-fitting equipment, specifically to a bearing cage assembly press-fitting device. Background Technology

[0002] Ball bearings consist of inner and outer rings, balls, and upper and lower cages. These components are assembled after production. The final step in the assembly process is to use an assembly machine to rivet and press the upper and lower cages together. Existing assembly machines generally consist of a machine body, a drive cylinder, an upper pressing component, and a lower pressing component. Patent number CN202421653167.3 discloses a bearing cage assembly pressing device. Multiple bearings are placed sequentially on a rotating table. As the piston rod of the drive cylinder moves downward, it drives the rotating table and multiple lower pressing components to rotate. The upper pressing component is moved downward by the piston rod and then cooperates with a rotating lower pressing component to press and rivet the cage. When the piston rod moves upward, the rotating table does not rotate. This cycle repeats automatically and simultaneously assembles multiple bearings, greatly improving operational efficiency. However, during the use of the bearing cage assembly pressing device, because the rack slides along the sliding rod and interlocks with the transmission box, and the rack is exposed on the outside, it is easy to get contaminated with some debris, which will have a certain impact on the operation of the rack and gear. Therefore, we propose a bearing cage assembly press-fitting device. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a bearing cage assembly press-fitting device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a bearing cage assembly pressing device, including a machine base. A bracket is mounted on one side of the top of the machine base, and a hydraulic rod is bolted to the top surface of the bracket. A pressing seat for pressing the bearing cage assembly is mounted on the power output end of the hydraulic rod, and an adjustment ring plate is bolted to the top surface of the pressing seat. A limiting ring seat is mounted on the top surface of the machine base, and a U-shaped vertical rod bolted to the ring plate is slidably installed on the inner side of the ring seat. An L-shaped plate that fits the U-shaped vertical rod is bolted to the top surface of the ring seat, and the L-shaped plate is inserted into the ring plate.

[0005] The inner side of the U-shaped vertical rod is fitted with a rack for transmission via screws, and a T-shaped disk is rotatably mounted on the top surface of the machine base. The top surface of the T-shaped disk is fitted with a clasp that matches the pressure seat via bolts, and there are multiple sets of clasps. A gear body that meshes with the rack is rotatably mounted on the inner side of the machine base, and a ratchet body that is connected to the gear body via bolts is also fitted on the inner side of the machine base. The power output end of the ratchet body is connected to a worm gear reducer that is bolted to the machine base via a rotating shaft. The power output end of the worm gear reducer is fitted with a straight shaft, and both the end of the straight shaft away from the worm gear reducer and the end of the T-shaped disk located on the inner side of the machine base are fitted with meshing bevel gears.

[0006] By adopting the above technical solution, during the use of the bearing cage assembly press-fitting equipment, the L-shaped plate on the surface of the ring seat and the groove on the inner circumference of the U-shaped vertical rod fit together and are inserted into the hole on the ring plate. This allows the L-shaped plate to slide against the U-shaped vertical rod as it moves up and down within the ring seat, protecting the rack on the inner circumference of the U-shaped vertical rod. This makes the rack operate more stably and reduces the contamination of external debris on the rack surface, making the rack more stable to use and facilitating transmission.

[0007] When the hydraulic rod is operated by the controller to push the pressure seat and the T-shaped plate to cooperate in pressing the bearing cage assembly, the downward displacement of the pressure seat can press the U-shaped vertical rod through the ring plate, so that the U-shaped vertical rod can slide along the inner circumference of the ring seat. The rack on the inner circumference of the U-shaped vertical rod can move synchronously and mesh with the gear body inside the machine tool, driving it to rotate. Then the gear body can provide power to the ratchet body, so that the power output end of the ratchet body can rotate and provide power to the worm gear reducer through the rotating shaft. Then the worm gear reducer operates conveniently, driving the bevel gear to rotate through the straight shaft and interacting with the T-shaped plate. The bevel gears located at one end of the machine tool mesh with each other, causing the T-shaped disk to rotate and engage with the descending pressure seat, facilitating the pressing of the bearing cage assembly. After pressing, the hydraulic rod operates and drives the pressure seat and ring plate back to their original positions. Due to the characteristics of the ratchet body, when the rack returns with the U-shaped vertical rod, the gear body cannot provide power to the worm gear reducer. This reciprocating motion causes the T-shaped disk to gradually rotate, making the clamp and pressure seat engage with each other, facilitating the pressing of the bearing cage. Furthermore, racks of appropriate length can be selected to work with the gears, allowing for easy control of the T-shaped disk's rotation angle according to usage requirements.

[0008] Specifically, the outer circumference of the L-shaped plate is integrally constructed with protrusions for limiting the position, and there are two sets of protrusions. The inner wall surface of the U-shaped vertical rod is provided with grooves that fit the protrusions, and there are two sets of grooves.

[0009] By adopting the above technical solution, the protrusions on both sides of the outer periphery of the L-shaped plate can fit into the groove on the inner periphery of the U-shaped vertical rod, which facilitates the improvement of the stability when the L-shaped plate and the U-shaped vertical rod are connected, and enables the L-shaped plate to more stably protect the rack on the inner periphery of the U-shaped vertical rod.

[0010] Specifically, the inner circumferential surface of the U-shaped vertical rod is provided with a sliding groove that matches the inner circumference of the ring seat, and the outer circumferential surface of the U-shaped vertical rod is provided with an arc-shaped groove that matches the inner circumference of the ring seat.

[0011] By adopting the above technical solution, a set of protrusions on the inner circumference of the ring seat can fit and slide with the groove on the inner circumference of the U-shaped vertical rod. At the same time, the arc groove on the outer circumference of the U-shaped vertical rod also fits with a set of protrusions on the inner circumference of the ring seat, thereby effectively improving the stability of the U-shaped vertical rod and the ring seat during mutual sliding displacement.

[0012] Specifically, the inner circumferential surface of the U-shaped vertical rod is integrally constructed with protrusions that fit with the rack.

[0013] By adopting the above technical solution, the protrusions on the inner circumference of the U-shaped vertical rod and the grooves on the back of the rack fit together, which facilitates the improvement of the stability of the rack installed on the inner circumference of the U-shaped vertical rod.

[0014] Specifically, the outer wall surface of the L-shaped plate is fitted with a vertical shaft that is inserted and connected to the ring plate.

[0015] By adopting the above technical solution, the vertical shaft on the L-shaped plate and the hole on the ring plate are interlocked and slidably connected, which facilitates further improvement in the stability of the ring plate and the U-shaped vertical rod during lifting and lowering displacement.

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

[0017] 1. The technical solution of this application, through the design of a ring seat, ring plate, rack, U-shaped vertical rod, and L-shaped plate, allows the L-shaped plate on the surface of the ring seat to fit into the groove on the inner circumference of the U-shaped vertical rod and to interlock with the hole on the ring plate during the use of the bearing cage assembly press-fitting equipment. This enables the L-shaped plate to slide against the U-shaped vertical rod as it moves up and down within the ring seat, protecting the rack on the inner circumference of the U-shaped vertical rod. This allows the rack to operate more stably and reduces the adhesion of external debris to the rack surface, making the rack more stable to use and facilitating transmission.

[0018] 2. The technical solution of this application, through the design of a bracket, hydraulic rod, pressure seat, T-shaped plate, clamp, bevel gear, ratchet body, worm gear reducer, straight shaft, and gear body, utilizes a controller to operate the hydraulic rod and push the pressure seat to cooperate with the clamp on the surface of the T-shaped plate to press the bearing cage assembly. The downward displacement of the pressure seat can press the U-shaped vertical rod through the ring plate, allowing the U-shaped vertical rod to slide along the inner circumference of the ring seat. The rack on the inner circumference of the U-shaped vertical rod can move synchronously and mesh with the gear body inside the machine tool, driving it to rotate. Subsequently, the gear body can provide power to the ratchet body, enabling the power output end of the ratchet body to rotate and provide power to the worm gear reducer through the rotating shaft. Then, the worm gear... The reducer operates conveniently by driving a bevel gear through a straight shaft to rotate and mesh with a bevel gear located at one end of a T-shaped disc inside the machine. This causes the T-shaped disc to rotate and engage with a descending pressure seat, facilitating the pressing of the bearing cage assembly. After pressing, the hydraulic rod operates and drives the pressure seat and ring plate back to their original positions. Due to the characteristics of the ratchet body, when the rack returns with the U-shaped vertical rod, the gear body cannot provide power to the worm gear reducer. This reciprocating motion causes the T-shaped disc to gradually rotate, allowing the chuck and pressure seat to engage with each other, facilitating the pressing of the bearing cage. Furthermore, a rack and gear of appropriate length can be selected for use, allowing for easy control of the T-shaped disc's rotation angle according to usage requirements.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a bearing cage assembly press-fitting device, including a machine base 1, a bracket 2 mounted on one side of the top of the machine base 1, and a hydraulic rod 3 mounted on the top surface of the bracket 2 by bolts. A press seat 4 for pressing the bearing cage assembly is mounted on the power output end of the hydraulic rod 3, and an adjustment ring plate 5 is mounted on the top surface of the press seat 4 by bolts. A limiting ring seat 6 is mounted on the top surface of the machine base 1, and a U-shaped vertical rod 7 bolted to the ring plate 5 is slidably installed on the inner side of the ring seat 6. An L-shaped plate 8 that fits the U-shaped vertical rod 7 is bolted to the top surface of the ring seat 6, and the L-shaped plate 8 is inserted into the ring plate 5. The inner side of the U-shaped vertical rod 7 is fitted with screws. A rack 11 is used for transmission, and a T-shaped disk 16 is rotatably mounted on the top surface of the machine base 1. A clasp 18 adapted to the pressure seat 4 is bolted to the top surface of the T-shaped disk 16, and there are multiple sets of clasp 18. A gear body 12 meshing with the rack 11 is rotatably mounted on the inner side of the machine base 1, and a ratchet body 13 connected to the gear body 12 is bolted to the inner side of the machine base 1. The power output end of the ratchet body 13 is connected to the worm gear reducer 14 bolted to the machine base 1 through a rotating shaft, and a straight shaft 15 is mounted on the power output end of the worm gear reducer 14. Both the end of the straight shaft 15 away from the worm gear reducer 14 and the end of the T-shaped disk 16 located on the inner side of the machine base 1 are equipped with bevel gears 17 that mesh with each other.

[0026] During use, when the bearing cage assembly press-fitting equipment is used, the L-shaped plate 8 on the surface of the ring seat 6 and the groove on the inner circumference of the U-shaped vertical rod 7 fit together and are inserted into the hole on the ring plate 5. This allows the L-shaped plate 8 to slide against the U-shaped vertical rod 7 as it moves up and down within the ring seat 6, and protects the rack 11 on the inner circumference of the U-shaped vertical rod 7. This makes the rack 11 operate more stably and reduces the contamination of external debris on the surface of the rack 11, making the rack 11 more stable to use and facilitating transmission.

[0027] When the hydraulic rod 3 is operated by the controller and pushes the pressure seat 4 to cooperate with the retainer 18 on the surface of the T-shaped plate 16 to press the bearing cage assembly, the downward displacement of the pressure seat 4 can press the U-shaped vertical rod 7 through the ring plate 5, so that the U-shaped vertical rod 7 can slide along the inner circumference of the ring seat 6. The rack 11 on the inner circumference of the U-shaped vertical rod 7 can move synchronously and mesh with the gear body 12 inside the machine tool 1, driving it to rotate. Then the gear body 12 can provide power to the ratchet body 13, so that the power output end of the ratchet body 13 can rotate and provide power to the worm gear reducer 14 through the rotating shaft. Then the worm gear reducer 14 operates conveniently and drives the bevel gear 17 to rotate through the straight shaft 15 and interact with the T-shaped plate 16. The bevel gears 17 at one end of the disc 16 inside the machine base 1 mesh with each other, causing the T-shaped disc 16 to rotate and engage with the descending pressure seat 4, facilitating the pressing of the bearing cage assembly. After pressing, the hydraulic rod 3 operates and drives the pressure seat 4 and the ring plate 5 back to their original positions. Due to the characteristics of the ratchet body 13, when the rack 11 returns with the U-shaped vertical rod 7, the gear body 12 cannot provide power to the worm gear reducer 14. In this reciprocating motion, the T-shaped disc 16 will gradually rotate and make the card seat 18 and the pressure seat 4 engage with each other, facilitating the pressing of the bearing cage. Furthermore, a rack 11 of appropriate length can be selected to engage with the gear, making it convenient to control the rotation angle of the T-shaped disc 16 according to the needs of use.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the outer circumference of the L-shaped plate 8 is integrally constructed with protrusions 9 for limiting, and there are two sets of protrusions 9. The inner wall surface of the U-shaped vertical rod 7 is provided with grooves 10 that fit with the protrusions 9, and there are two sets of grooves 10.

[0029] When in use, the protruding strips 9 on both sides of the outer periphery of the L-shaped plate 8 can fit into the groove 10 on the inner periphery of the U-shaped vertical rod 7, which can improve the stability of the L-shaped plate 8 and the U-shaped vertical rod 7 when they fit together, so that the L-shaped plate 8 can more stably protect the rack 11 on the inner periphery of the U-shaped vertical rod 7.

[0030] like Figure 1 and Figure 2 As shown, the inner circumferential surface of the U-shaped vertical rod 7 is provided with a sliding groove 22 that matches the inner circumference of the ring seat 6, and the outer circumferential surface of the U-shaped vertical rod 7 is provided with an arc-shaped groove 20 that matches the inner circumference of the ring seat 6.

[0031] In use, a set of protrusions on the inner circumference of the ring seat 6 can engage with and slide against the sliding groove 22 on the inner circumference of the U-shaped vertical rod 7. At the same time, the arc groove 20 on the outer circumference of the U-shaped vertical rod 7 also engages with a set of protrusions on the inner circumference of the ring seat 6, thereby effectively improving the stability of the sliding displacement between the U-shaped vertical rod 7 and the ring seat 6.

[0032] like Figure 2As shown, the inner circumferential surface of the U-shaped vertical rod 7 has an integrally constructed protrusion 21 that matches the rack 11.

[0033] When in use, the protrusion 21 on the inner circumference of the U-shaped vertical rod 7 fits into the groove on the back of the rack 11, which facilitates the improvement of the stability of the rack 11 installed on the inner circumference of the U-shaped vertical rod 7.

[0034] like Figure 1 and Figure 3 As shown, the outer wall surface of the L-shaped plate 8 is fitted with a vertical shaft 19 that is inserted and connected to the ring plate 5.

[0035] During use, the vertical shaft 19 on the L-shaped plate 8 and the hole on the ring plate 5 are interlocked and slidably connected, which facilitates further improvement of the stability of the ring plate 5 and the U-shaped vertical rod 7 during lifting and lowering displacement.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in the appropriate positions. During the pressing process of the bearing cage assembly, the L-shaped plate 8 on the surface of the ring seat 6 and the groove on the inner circumference of the U-shaped vertical rod 7 fit together and interlock with the hole on the ring plate 5. This allows the L-shaped plate 8 to slide relative to the U-shaped vertical rod 7 as it rises and falls within the inner circumference of the ring seat 6, protecting the rack 11 on the inner circumference of the U-shaped vertical rod 7. This ensures more stable operation of the rack 11 and reduces the contamination of external debris. The surface condition of rack 11 allows for more stable operation and facilitates transmission. Simultaneously, when the controller operates the hydraulic rod 3 to push the pressure seat 4 and the holder 18 on the surface of the T-shaped disc 16 to press the bearing cage assembly, the downward displacement of the pressure seat 4 can press the U-shaped vertical rod 7 through the ring plate 5. This allows the U-shaped vertical rod 7 to slide along the inner circumference of the ring seat 6. The rack 11 on the inner circumference of the U-shaped vertical rod 7 can move synchronously and mesh with the gear body 12 inside the machine tool 1, driving the machine. The gear body 12 rotates, and then the gear body 12 provides power to the ratchet body 13, enabling the power output end of the ratchet body 13 to rotate and provide power to the worm gear reducer 14 through the rotating shaft. The worm gear reducer 14 then operates smoothly, driving the bevel gear 17 to rotate via the straight shaft 15. This bevel gear 17 meshes with the T-shaped disk 16 located at one end of the machine base 1, causing the T-shaped disk 16 to rotate accordingly and engage with the descending pressure seat 4, facilitating the pressing of the bearing cage assembly. After pressing, the hydraulic rod 3 operates and... When the dynamic pressure seat 4 and the ring plate 5 return to their original positions, due to the characteristics of the ratchet body 13, the rack 11 returns with the U-shaped vertical rod 7, and the gear body 12 cannot provide power to the worm gear reducer 14. In this way, the T-shaped disk 16 will gradually jump and make the card seat 18 and the pressure seat 4 cooperate with each other, which facilitates the pressing of the bearing cage. The rack 11 of appropriate length can be selected to cooperate with the gear, and the rotation angle of the T-shaped disk 16 can be easily controlled according to the needs of use, making the bearing pressing equipment more convenient to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
