Description

Technical Field

[0001] This utility model relates to the field of bearing cover processing technology, and more specifically, it relates to a grinding device for bearing cover processing. Background Technology

[0002] In the bearing manufacturing and precision machining industries, bearing caps, as critical components, require rigorous precision machining processes to ensure their surface quality and dimensional accuracy meet industry standards. Traditional bearing cap grinding processes necessitate frequent changes of grinding tools of different specifications and wear levels to adapt to varying processing stages and surface requirements.

[0003] However, existing grinding equipment typically uses threaded connections or snap-fit ​​fixing methods to install grinding heads. This design often requires the use of special tools for disassembly and installation when the grinding head needs to be replaced, which is not only time-consuming but also prone to excessive wear of connecting parts in a production environment with high-frequency replacements. In addition, the complex disassembly and assembly process increases production downtime, reduces processing efficiency, and also increases the labor intensity of operators, which is not conducive to achieving high-efficiency and standardized production of bearing cover processing.

[0004] In the mass production of precision bearing caps, it is necessary to fix and position a large number of bearing caps with similar specifications but different dimensions to ensure the stability and machining accuracy of the grinding process. The clamping mechanisms in existing grinding equipment generally suffer from poor adaptability and cumbersome adjustment, making it difficult to meet the rapid clamping requirements of bearing caps of different sizes. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, the present invention provides a grinding device for processing bearing caps, so as to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing bearing caps, comprising a support frame, a linkage component mounted on the support frame, a fixed block connected to the linkage component, a drive motor fixed on the fixed block, a quick-release mechanism provided at the output end of the drive motor, the quick-release mechanism comprising a fixed sleeve and a rod, the fixed sleeve being fixed to the output end of the drive motor, the rod being inserted into the fixed sleeve, a grinding head fixed at the bottom end of the rod, a snap-fit ​​plate fixed on the inner side of the fixed sleeve, multiple sets of snap-fit ​​plates, a snap-fit ​​groove and a guide groove on the outer wall of the rod, a guide plate fixed on the inner wall of the fixed sleeve, multiple sets of guide plates and guide grooves being provided and slidably connected, a sliding sleeve slidably provided on the outer side of the fixed sleeve, a sliding groove on the outer wall of the fixed sleeve, multiple sets of sliding grooves being provided and slidably connected to the sliding sleeve, and a push plate with multiple sets of push plates fixed on the inner side of the sliding sleeve.

[0009] The present invention is further configured such that a limiting block is slidably provided on the outer wall of the sliding sleeve, and multiple sets of the limiting block are provided; a limiting groove is provided on the outer wall of the fixed sleeve, and multiple sets of the limiting groove are provided and respectively abut against multiple sets of limiting blocks; a limiting sleeve is rotatably provided on the outer wall of the fixed sleeve; a limiting plate is fixedly provided on the outer wall of the limiting sleeve, and multiple sets of the limiting plate are provided and respectively abut against the outer wall of multiple sets of limiting blocks. This multi-limiting structure forms a reliable locking system to prevent the sliding sleeve from moving accidentally due to vibration during the grinding process. At the same time, the abutting design between the limiting plate and the limiting block allows the limiting mechanism to be released by a simple rotation operation, improving the convenience and safety of disassembly.

[0010] The present invention is further configured such that a reset spring is connected between the top of each of the multiple sets of limiting blocks and the outer wall of the sliding sleeve. The reset spring enables the limiting blocks to move upward and disengage from the limiting groove after the limiting is released, eliminating the need for manual removal, which greatly simplifies the unlocking operation, improves work efficiency, and ensures that all limiting blocks can move synchronously, thus guaranteeing the reliability of the unlocking process.

[0011] The present invention is further configured such that a positioning sleeve is fixedly provided on the bottom surface of the limiting sleeve, and a sliding hole is provided on the inner side of the positioning sleeve. Multiple sets of sliding holes are provided, and each set of sliding holes is connected to a push spring on its inner side. A positioning block is fixedly provided at the bottom end of each set of push springs. The multiple sets of positioning blocks are slidably connected to the multiple sets of sliding holes. A positioning groove is provided on the outer wall of the fixed sleeve, and multiple sets of positioning grooves are provided. This positioning mechanism ensures precise angle control when the limiting sleeve rotates, preventing over-rotation or under-rotation from causing unlocking failure. At the same time, the elastic connection between the push spring and the positioning block provides clear tactile feedback for operation, allowing the operator to clearly perceive the unlocking status.

[0012] The present invention is further configured such that the outer sides of the multiple sets of positioning grooves and the bottom ends of the positioning blocks are all arc-shaped and abut against each other. The arc-shaped design allows the positioning blocks to smoothly slide into and out of the positioning grooves during rotation, reducing frictional resistance and wear, while providing a smooth operating experience, extending the service life of the mechanism, and improving the reliability and durability of the device under long-term and frequent use conditions.

[0013] The present invention is further configured such that a compression spring is connected inside the insertion rod, and multiple sets of compression springs are provided. An abutment plate is fixedly provided at the top of the fixing sleeve, and the abutment plate abuts against the top of the multiple sets of compression springs. The combination design of multiple sets of compression springs and abutment plates realizes the automatic pop-out function of the insertion rod. After the snap plate is disengaged from the snap slot, the grinding head can be separated without manual pulling, which greatly improves the replacement efficiency. At the same time, the multi-point elastic force distribution ensures the uniformity and stability of the pop-out force.

[0014] The present invention is further configured such that all of the multiple sets of snap-fit ​​plates are elastic plates, and the tops of all of the multiple sets of push plates are arc-shaped. The elastic plate design gives the snap-fit ​​plates good deformation and rebound performance, ensuring that they can maintain a good snap-fit ​​effect after multiple uses. The arc-shaped design at the top of the push plate can smoothly push the snap-fit ​​plates to deform, reduce stress concentration at sharp corners, reduce wear and fatigue risk of parts, and extend the service life of the entire quick-release mechanism.

[0015] The present invention is further configured such that an mounting plate is fixedly provided on the support frame, and multiple clamping mechanisms are provided on the mounting plate. Each clamping mechanism includes a slide and a clamping block. The slide is fixed on the mounting plate, and the clamping block slides inside the slide. A top block is fixedly provided at the top of the slide, and a hydraulic cylinder is fixedly provided on the outer wall of the slide. The telescopic end of the hydraulic cylinder is fixed on the outer wall of the clamping block, and a tension spring is provided between the slide sleeve and the fixed sleeve.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a grinding device for processing bearing caps, which has the following beneficial effects:

[0018] 1. This grinding device, through its innovative quick-installation mechanism design, enables rapid installation and removal of the grinding head, effectively solving the problem of frequent tool changes in the bearing manufacturing and precision machining industries. The ingenious cooperation between the fixing sleeve and the insertion rod, combined with the locking structure of the snap-fit ​​plate and the snap-fit ​​groove, allows operators to install the grinding head without any tools, greatly shortening tool change time and improving production efficiency. At the same time, the sliding connection design of the guide plate and the guide groove ensures precise positioning during the installation of the grinding head, avoiding processing quality problems caused by installation deviations, and significantly reducing the labor intensity and technical requirements of operators.

[0019] 2. This device employs a meticulously designed disassembly mechanism. Through the coordinated work of the limiting sleeve, limiting block, and limiting plate, combined with the precise positioning system of the positioning sleeve, positioning block, and positioning groove, a safe and reliable grinding head disassembly process is formed. The operator only needs to rotate the limiting sleeve to start the entire disassembly system. Under the action of the return spring, the limiting block disengages from the limiting groove, releasing the limiting of the sliding sleeve. The sliding sleeve drives the push plate to push the snap plate to deform and disengage from the snap groove. Finally, the spring force of the compression spring causes the insertion rod to automatically pop out of the fixing sleeve. The whole process is highly automated and easy to operate, making it particularly suitable for use in production environments with high-frequency grinding head replacement. It effectively solves the problems of complex disassembly process, long time consumption, and easy wear of parts in traditional grinding devices.

[0020] 3. This device also features a highly efficient clamping mechanism. Through the combined application of a slide block, clamping blocks, and hydraulic cylinders, it achieves rapid clamping and precise positioning of bearing caps of different sizes. The clamping space formed between the top block and the clamping blocks can be automatically adjusted according to the size of the bearing cap. The stable pressure provided by the hydraulic cylinders ensures the workpiece is firmly fixed during the grinding process, preventing the workpiece from loosening or shifting, which would lead to a decrease in processing accuracy. At the same time, the mounting plate on the support frame can be equipped with multiple clamping mechanisms simultaneously, enabling batch processing. Combined with the drive mechanism driven by the linkage components, the entire grinding process becomes more efficient and stable, significantly improving the production efficiency and product quality of bearing cap processing, and meeting the urgent needs of modern manufacturing for efficient and precise processing.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] Please see Figures 1-5 A grinding device for processing bearing caps includes a support frame 1, a linkage component 2 mounted on the support frame 1, a fixed block 3 connected to the linkage component 2, a drive motor 4 fixed on the fixed block 3, a quick-release mechanism at the output end of the drive motor 4, the quick-release mechanism including a fixed sleeve 5 and a plug rod 6, the fixed sleeve 5 fixed to the output end of the drive motor 4, the plug rod 6 inserted into the fixed sleeve 5, a grinding head 7 fixed at the bottom end of the plug rod 6, a snap-fit ​​plate 8 fixed on the inner side of the fixed sleeve 5, multiple sets of snap-fit ​​plates 8, a snap-fit ​​groove 9 and a guide groove 10 on the outer wall of the plug rod 6, a guide plate 11 fixed on the inner wall of the fixed sleeve 5, multiple sets of guide plates 11 and guide grooves 10 slidably connected, a sliding sleeve 12 slidably provided on the outer side of the fixed sleeve 5, a sliding groove 13 on the outer wall of the fixed sleeve 5, multiple sets of sliding grooves 13 slidably connected to the sliding sleeve 12, and a push plate 14 fixed on the inner side of the sliding sleeve 12, multiple sets of push plates 14.

[0031] The outer wall of the sliding sleeve 12 is provided with a limiting block 15, and multiple sets of limiting blocks 15 are provided. The outer wall of the fixed sleeve 5 is provided with a limiting groove 16, and multiple sets of limiting grooves 16 are provided, each abutting against multiple sets of limiting blocks 15. The outer wall of the fixed sleeve 5 is provided with a limiting sleeve 17, and the outer wall of the limiting sleeve 17 is fixedly provided with a limiting plate 18, which is provided in multiple sets and abutting against the outer wall of multiple sets of limiting blocks 15. This structure forms a limiting locking system. When multiple sets of limiting blocks 15 are inserted into the limiting grooves 16, they can prevent the sliding sleeve 12 from moving and maintain the locked state. The limiting sleeve 17 abuts against the outer wall of the limiting block 15 through the limiting plate 18 on its outer wall, forming a secondary locking protection. When the limiting sleeve 17 is rotated, the limiting plate 18 will disengage from the limiting block 15, allowing the limiting block 15 to move upward and disengage from the limiting groove 16 in subsequent steps, thereby starting the entire unlocking process.

[0032] Each of the multiple sets of limiting blocks 15 is connected to a return spring 19 between its top and the outer wall of the sliding sleeve 12. This design constitutes an automatic reset mechanism for the limiting blocks 15. When the limiting plate 18 no longer abuts against the outer wall of the limiting block 15, the tension of the return spring 19 will cause the limiting block 15 to move upward, so that its bottom end automatically disengages from the limiting groove 16. The limiting of the sliding sleeve 12 can be released without manual operation, creating conditions for the next movement of the sliding sleeve 12.

[0033] A positioning sleeve 20 is fixedly provided on the bottom surface of the limiting sleeve 17. A sliding hole 21 is provided on the inner side of the positioning sleeve 20. Multiple sets of sliding holes 21 are provided, and each set of sliding holes 21 is connected to a push spring 22. A positioning block 23 is fixedly provided at the bottom end of each set of push springs 22. The multiple sets of positioning blocks 23 are slidably connected to the multiple sets of sliding holes 21. A positioning groove 24 is provided on the outer wall of the fixed sleeve 5. Multiple sets of positioning grooves 24 are provided. This mechanism forms a positioning control system. The positioning sleeve 20 rotates together with the limiting sleeve 17. The positioning block 23 inside is inserted into the positioning groove 24 on the outer wall of the fixed sleeve 5 under the action of the push spring 22, so as to achieve precise control of the rotation position of the limiting sleeve 17. When the limiting sleeve 17 is rotated, the positioning block 23 is forced to leave the positioning groove 24 and compress the push spring 22, preparing for the next position positioning.

[0034] The outer sides of multiple positioning grooves 24 and the bottom of positioning blocks 23 are all set to be arc-shaped and abut against each other. This design adopts a humanized arc transition structure. The arc-shaped design of the outer sides of positioning grooves 24 and the bottom of positioning blocks 23 allows the two to smoothly transition during relative sliding, reducing resistance and impact during rotation, while reducing friction and wear, and improving the service life and operating comfort of positioning components.

[0035] The insert rod 6 is internally connected to a compression spring 25, and multiple sets of compression springs 25 are provided. The top of the fixed sleeve 5 is fixed with an abutment plate 26, which abuts against the top of the multiple sets of compression springs 25. This device constitutes an automatic ejection system for the insert rod 6. When the insert rod 6 is inserted into the fixed sleeve 5, the multiple sets of compression springs 25 are compressed and abut against the abutment plate 26. When the locking mechanism is released, these compressed compression springs 25 will release energy and transmit the force to the insert rod 6 through the abutment plate 26, so that it automatically ejects from the fixed sleeve 5, completing the quick disassembly of the grinding head 7.

[0036] All sets of snap-fit ​​plates 8 are designed as elastic plates, and the tops of all sets of push plates 14 are designed as arc-shaped. This structure is designed with a flexible snap-fit ​​and unlocking mechanism. The elastic snap-fit ​​plates 8 can undergo elastic deformation during insertion and removal to ensure reliable snap-fit ​​and separation with the slot 9. The arc-shaped design at the top of the push plate 14 can smoothly push the snap-fit ​​plates 8 to deform with minimal resistance when the sliding sleeve 12 drives the push plate 14 to move, so as to disengage them from the slot 9 and ensure the smoothness of the unlocking operation.

[0037] A mounting plate 27 is fixedly installed on the support frame 1. Multiple clamping mechanisms are provided on the mounting plate 27. The clamping mechanism includes a slide 28 and a clamping block 29. The slide 28 is fixed on the mounting plate 27. The clamping block 29 slides inside the slide 28. A top block 30 is fixedly installed at the top of the slide 28. A hydraulic cylinder 31 is fixedly installed on the outer wall of the slide 28. The telescopic end of the hydraulic cylinder 31 is fixed to the outer wall of the clamping block 29. A tension spring 32 is provided between the sliding sleeve 12 and the fixed sleeve 5.

[0038] In this embodiment, during use, the bearing cover is placed between the top block 30 and the clamping block 29. The clamping block 29 is pushed by the telescopic end of the hydraulic cylinder 31 to fix the bearing cover. The insert rod 6 is inserted into the fixing sleeve 5. Multiple sets of guide plates 11 are inserted into the guide holes, and multiple sets of push plates 14 are placed in the guide groove 10. Multiple sets of compression springs 25 are compressed by the abutment plate 26. Multiple sets of snap-fit ​​plates 8 are deformed and bent by the top of the insert rod 6. When multiple sets of snap-fit ​​plates 8 are in the slot 9, they are reset and abut against the inner wall of the slot 9, thereby completing the installation of the grinding head 7. The grinding head 7 is driven to rotate by the drive motor 4, and the drive frame and grinding head 7 are driven by the linkage component 2 to grind the bearing cover.

[0039] More specifically, when the grinding head 7 needs to be replaced, the rotating limiting sleeve 17 drives multiple sets of limiting plates 18 to release the contact with multiple sets of limiting blocks 15, and at the same time drives the positioning sleeve 20 to rotate. Through multiple sets of positioning grooves 24, the positioning block 23 is pushed to slide along the sliding hole 21 and squeeze the push spring 22, so that the multiple sets of positioning blocks 23 continue to move within the multiple sets of positioning grooves 24. Through multiple sets of reset springs 19, the limiting block 15 is pulled so that its bottom end is disengaged from the limiting groove 16 to release the limiting of the sliding sleeve 12. Through the tension spring 32, the sliding sleeve 12 is pulled to slide along multiple sets of sliding grooves 13, and through the sliding sleeve 12, multiple sets of push plates 14 push multiple sets of snap-fit ​​plates 8, so that the multiple sets of snap-fit ​​plates 8 deform and disengage from the snap-fit ​​groove 9, releasing the snap-fit ​​of the insertion rod 6. Through multiple sets of compression springs 25, the insertion rod 6 is reset and pushed out of the fixing sleeve 5, completing the disassembly of the grinding head 7.

[0040] In summary, during use or operation of the overall equipment: When in use, the bearing cover is placed between the top block 30 and the clamping block 29. The clamping block 29 is pushed by the telescopic end of the hydraulic cylinder 31 to fix the bearing cover. The insert rod 6 is inserted into the fixing sleeve 5. Multiple sets of guide plates 11 are inserted into the guide holes, and multiple sets of push plates 14 are placed in the guide groove 10. Multiple sets of compression springs 25 are compressed by the abutment plate 26. Multiple sets of snap-fit ​​plates 8 are deformed and bent by the top of the insert rod 6. When multiple sets of snap-fit ​​plates 8 are in the slot 9, they are reset and abut against the inner wall of the slot 9, thereby completing the installation of the grinding head 7. The grinding head 7 is driven to rotate by the drive motor 4. The drive frame and the grinding head 7 are driven by the linkage component 2 to grind the bearing cover.

[0041] When the grinding head 7 needs to be replaced, the rotating limiting sleeve 17 drives multiple sets of limiting plates 18 to release the contact with multiple sets of limiting blocks 15, and at the same time drives the positioning sleeve 20 to rotate. Through multiple sets of positioning grooves 24, the positioning block 23 is pushed to slide along the sliding hole 21 and squeeze the push spring 22, so that the multiple sets of positioning blocks 23 continue to move in the multiple sets of positioning grooves 24. Through multiple sets of reset springs 19, the limiting block 15 is pulled so that its bottom end is disengaged from the limiting groove 16 to release the limitation on the sliding sleeve 12. Through the tension spring 32, the sliding sleeve 12 is pulled to slide along multiple sets of sliding grooves 13, and through the sliding sleeve 12, multiple sets of push plates 14 push multiple sets of snap-fit ​​plates 8, so that the multiple sets of snap-fit ​​plates 8 deform and disengage from the snap-fit ​​groove 9, releasing the snap-fit ​​on the insertion rod 6. Through multiple sets of compression springs 25, the insertion rod 6 is reset and pushed out of the fixing sleeve 5, completing the disassembly of the grinding head 7.
