Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing press-fitting technology, specifically to a press-fitting bearing fixture. Background Technology
[0002] Bearing press fitting is the process of installing a bearing into a shaft or bearing housing bore. An interference fit is usually used between the bearing and the bearing housing bore to ensure that there is no relative sliding or rotation during operation. According to the fit between the bearing and the bearing housing bore, a suitable press is selected for press fitting. The pressing force should be applied directly to the end face of the interference fit ring.
[0003] While existing pressing devices offer numerous advantages during use, they still suffer from the following problems: insufficient protection of the pressing area; misalignment or excessive pressure between the bearing and bearing housing bore during pressing can damage the bearing or bearing housing bore; debris from the broken parts can fly out and injure personnel near the equipment, affecting the safety of equipment use. Summary of the Invention
[0004] In view of the problems in the prior art, this utility model provides a press-fit bearing fixture.
[0005] The technical solution adopted by this utility model to solve its technical problem is a press-fit bearing fixture, including a cabinet, a workbench and a ferrule. A pressure cylinder is provided on one side of the upper end of the inner wall of the cabinet, a push rod is provided on one side of the lower outer wall of the pressure cylinder, and a pressure plate is provided on the lower outer wall of the push rod. A workbench is rotatably installed on one side of the inner wall of the cabinet. A partition plate is welded to one side of the inner wall of the cabinet, and an observation window is embedded in the partition plate. Ferrules are symmetrically welded to both outer walls of the partition plate. A limit rod is welded to one outer wall of the ferrule, a sliding block is slidably installed on one outer wall of the limit rod, and a baffle is welded to one outer wall of the sliding block.
[0006] By adopting the above technical solution, the pressure cylinder can drive the push rod to move vertically, thereby enabling the pressure plate to press-fit the bearing and bearing seat placed inside the limiting groove, achieving precise pressing-fit of the bearing. Furthermore, since the worktable can rotate, the positions of the two support plates can be interchanged. During the pressing-fitting of bearings inside one support plate, bearings inside the other support plate can be disassembled and assembled, improving the pressing-fitting efficiency. The partition plate, in conjunction with the worktable, can shield and seal the inside of the cabinet, ensuring a relatively sealed environment for bearing pressing, preventing debris from flying, and improving worker safety. Workers can observe the displacement of the pressure plate through the observation window, allowing for timely adjustments to the pressing position between the pressure plate and the bearing, ensuring the accuracy of bearing pressing. The baffle can also shield the observation window, preventing damage from debris during the pressing process and ensuring its service life.
[0007] Specifically, connecting frames are welded to the outer walls of both sides of the push rod, a drive plate is slidably installed on one side of the outer wall of the connecting frame, a first spring is provided on one side of the outer wall of the connecting frame, and the drive plate is elastically connected to the inner wall of the connecting frame through the first spring.
[0008] By adopting the above technical solution, when the push rod is driven to move by the pressure cylinder, it can drive the connecting frame to move, so that the drive plate and the linkage plate come into contact. Through the continuous movement of the push rod, due to the magnetic attraction of the magnet to the linkage plate, the first spring is compressed and stores energy. When the first spring reaches the compression limit, the hard contact between the connecting frame and the drive plate pushes the linkage plate to move. Thus, the elastic energy of the first spring can cause the baffle to move down quickly to block and protect the observation window. Before the first spring reaches the compression limit, the bearing of the pressure plate and the limiting groove is in the initial contact state. Therefore, the bearing is not compressed and no debris is generated. Thus, the operator can observe the position of the pressure plate through the observation window and adjust the position of the worktable or pressure plate in a timely manner.
[0009] Specifically, material support plates are installed on both sides of the upper outer wall of the workbench. Limiting grooves are opened on the upper outer wall of the material support plates. The limiting grooves adopt a stepped design. The two material support plates are distributed on both sides of the partition plate, and the pressure plate is located at the upper end of the limiting groove.
[0010] By adopting the above technical solution, the limiting groove design on the support plate provides precise positioning and support for the placement and pressing of bearings. The stepped design of the limiting groove can accommodate bearings of different sizes, improving the versatility and flexibility of the fixture. At the same time, the pressure plate is located at the upper end of the limiting groove, ensuring that the bearing receives uniform and stable pressure during the pressing process, avoiding the risk of bearing deformation or damage.
[0011] Specifically, a magnet is embedded in one side of the outer wall of the card sleeve, and the magnet is attracted to the sliding block. A buffer pad is attached and fixed to one side of the outer wall of the card sleeve.
[0012] By adopting the above technical solution, the adsorption force between the magnet and the sliding block can limit the position of the baffle, ensuring that the baffle moves in a controlled manner, and the buffer pad can protect the baffle, preventing the baffle and the sleeve from colliding with each other, thus ensuring the service life of the baffle.
[0013] Specifically, linkage plates are installed on both sides of the upper end of the outer wall of the baffle, and the linkage plates are in contact with the drive plate.
[0014] By adopting the above technical solution, the baffle can automatically adjust its position as the drive plate moves during the pressing process. This design not only simplifies the operation steps and improves work efficiency, but also ensures that the baffle is controlled to block the observation window during the pressing process, protects the observation window during pressing, and allows the staff to observe the position of the pressing plate through the observation window when not pressing.
[0015] Specifically, a second spring is provided on one side of the outer wall of the limiting rod, and the sliding block is elastically connected to the sleeve through the second spring.
[0016] By adopting the above technical solution, the second spring force can push the sliding block, and when the pressure plate is reset, the second spring force can assist the baffle in resetting, and the force of the second spring is less than that of the first spring.
[0017] Specifically, the baffle is located inside the cabinet, and the size of the baffle is larger than the size of the observation window.
[0018] By adopting the above technical solution, the baffle can move vertically in a controlled manner inside the cabinet, and when the baffle is closed, it can completely cover the observation window, preventing damage to the observation window from splashes or fragments generated during the pressing process. At the same time, this design can also protect the safety of operators and avoid the risk of injury caused by splashes or fragments.
[0019] The beneficial effects of this utility model are:
[0020] The present invention provides a press-fit bearing fixture that allows for the interchange of the positions of the two bearing plates. During the press-fitting of a bearing inside one bearing plate, the bearing inside the other bearing plate can be disassembled and assembled, thereby improving the press-fitting efficiency of the bearing.
[0021] The present invention provides a press-fit bearing fixture that shields and seals the inside of the cabinet, ensuring a relatively sealed environment for bearing press-fitting, preventing debris from flying out, and improving the safety of workers. Attached Figure Description

[0029] 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.
[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the bearing clamp of this utility model includes a cabinet 1, a workbench 2, and a ferrule 3. A pressure cylinder 11 is provided on one side of the upper end of the inner wall of the cabinet 1. A push rod 12 is provided on one side of the lower outer wall of the pressure cylinder 11. A pressure plate 13 is provided on the lower outer wall of the push rod 12. The workbench 2 is rotatably installed on one side of the inner wall of the cabinet 1. A partition plate 22 is welded on one side of the inner wall of the cabinet 1. An observation window 23 is embedded in the partition plate 22. Ferrules 3 are symmetrically welded on both sides of the outer wall of the partition plate 22. A limit rod 31 is welded on one side of the outer wall of the ferrule 3. A sliding block 35 is slidably installed on one side of the outer wall of the limit rod 31. A baffle 36 is welded on one side of the outer wall of the sliding block 35.
[0031] During use, the pressure cylinder 11 drives the push rod 12 to move vertically, thereby enabling the pressure plate 13 to press-fit the bearing and bearing seat placed inside the limiting groove, achieving precise pressing of the bearing. Since the worktable 2 can rotate, the positions of the two support plates 21 can be interchanged. During the pressing of the bearing inside one support plate 21, the bearing inside the other support plate 21 can be disassembled and assembled, improving the pressing efficiency of the bearing. The partition plate 22 can work with the worktable 2 to shield and seal the inside of the cabinet 1, ensuring the relative sealing of the bearing pressing environment, preventing debris from flying, and improving the safety of the workers. The workers can observe the displacement position of the pressure plate 13 through the observation window 23, helping them to adjust the pressing position between the pressure plate 13 and the bearing in a timely manner, ensuring the accuracy of the bearing pressing. The baffle 36 can shield the observation window 23 to prevent debris from damaging the observation window 23 during the pressing process, ensuring the service life of the observation window 23.
[0032] For example, to enable coordinated movement, such as... Figure 4 As shown, connecting frames 14 are welded to both outer walls of the push rod 12. A drive plate 16 is slidably installed on one outer wall of the connecting frame 14. A first spring 15 is provided on one outer wall of the connecting frame 14, and the drive plate 16 is elastically connected to the inner wall of the connecting frame 14 through the first spring 15.
[0033] When in use, the push rod 12 is driven to move by the pressure cylinder 11, which in turn moves the connecting frame 14, causing the drive plate 16 to contact the linkage plate 37. Through the continuous movement of the push rod 12, the magnetic force of the magnet 34 attracts the linkage plate 37, causing the first spring 15 to compress and store energy. When the first spring 15 reaches its compression limit, the hard contact between the connecting frame 14 and the drive plate 16 pushes the linkage plate 37 to move. Thus, the release of the elastic energy of the first spring 15 allows the baffle 36 to move down quickly to block and protect the observation window 23. Before the first spring 15 reaches its compression limit, the bearing of the pressure plate 13 and the limiting groove are in the initial contact state. Therefore, the bearing is not compressed and no debris is generated. Thus, the operator can observe the position of the pressure plate 13 through the observation window 23 and adjust the position of the worktable 2 or the pressure plate 13 in a timely manner.
[0034] For the purpose of limiting, for example, such as Figure 1 As shown, material support plates 21 are installed on both sides of the upper outer wall of the workbench 2. The upper outer wall of the material support plate 21 has a limiting groove. The limiting groove adopts a stepped design. The two material support plates 21 are distributed on both sides of the partition plate 22, and the pressure plate 13 is located at the upper end of the limiting groove.
[0035] During use, the limiting groove design on the support plate 21 provides precise positioning and support for the placement and pressing of the bearing. The stepped design of the limiting groove can adapt to bearings of different sizes, improving the versatility and flexibility of the fixture. At the same time, the pressure plate 13 is located at the upper end of the limiting groove, which can ensure that the bearing is subjected to uniform and stable pressure during the pressing process, avoiding the risk of bearing deformation or damage.
[0036] To maintain the usage location, for example, such as Figure 5 As shown, a magnet 34 is embedded in the outer wall of one side of the card sleeve 3, and the magnet 34 is attracted to the sliding block 35. A buffer pad 33 is attached and fixed to the outer wall of one side of the card sleeve 3.
[0037] During use, the attraction between the magnet 34 and the sliding block 35 can restrict the position of the baffle 36, ensuring that the baffle 36 moves in a controlled manner, and the buffer pad 33 can protect the baffle 36, preventing the baffle 36 from colliding with the sleeve 3, thus ensuring the service life of the baffle 36.
[0038] To drive movement, for example, such as Figure 1 As shown, linkage plates 37 are installed on both sides of the upper end of the outer wall of the baffle 36, and the linkage plates 37 are in contact with the drive plate 16.
[0039] During use, the baffle 36 can automatically adjust its position as the drive plate 16 moves during the pressing process. This design not only simplifies the operation steps and improves work efficiency, but also ensures that the baffle 36 can controllably block the observation window 23 during the pressing process, protect the observation window 23 during pressing, and allow the staff to observe the position of the pressing plate 13 through the observation window 23 when not pressing.
[0040] To reset the slider 35, for example, as follows: Figure 5 As shown, a second spring 32 is provided on the outer wall of one side of the limiting rod 31, and the sliding block 35 is elastically connected to the sleeve 3 through the second spring 32.
[0041] In use, the second spring 32 can push the sliding block 35 with its elastic force, and when the pressure plate 13 is reset, the baffle 36 can be reset with the elastic force of the second spring 32, and the elastic force of the second spring 32 is less than the elastic force of the first spring 15.
[0042] To protect the viewing window 23, for example, such as Figure 1 As shown, the baffle 36 is located inside the cabinet 1, and the size of the baffle 36 is larger than the size of the observation window 23.
[0043] When in use, the baffle 36 can move vertically in a controlled manner inside the cabinet 1, and when the baffle 36 is closed, it can completely cover the observation window 23, preventing splashes or fragments generated during the pressing process from damaging the observation window 23. At the same time, this design can also protect the safety of operators and avoid the risk of injury caused by splashes or fragments.
[0044] When using this utility model, the bearing to be pressed and its bearing seat are accurately placed in the limiting groove on the support plate 21. Since the limiting groove adopts a stepped design, it can adapt to bearings of different sizes. According to the bearing position to be pressed, the worktable 2 is rotated so that the support plate 21 is in a suitable pressing position. The worktable 2 can rotate, so that when pressing the bearing on one side of the support plate 21, the other side of the support plate 21 can be used for disassembly or preparation of the next bearing.
[0045] Start the pressure cylinder 11, which drives the push rod 12 to move vertically downward. The movement of the push rod 12 causes the connecting frame 14 and its drive plate 16 to move together. As the push rod 12 continues to move, the drive plate 16 gradually approaches and contacts the linkage plate 37. At this time, the first spring 15 begins to be compressed, and at the same time, the magnetic force of the magnet 34 attracts the linkage plate 37, keeping the baffle 36 in the initial position. Before the first spring 15 is compressed to its limit, the pressure plate 13 and the bearing in the limiting groove are in the initial contact state and no pressure has been applied. At this time, the operator can observe the position of the pressure plate 13 and the relative position between the pressure plate 13 and the bearing through the observation window 23. If the position is found to be inaccurate, the pressing process can be paused and the position of the worktable 2 or the pressure plate 13 can be adjusted.
[0046] When the first spring 15 is compressed to its limit, the linkage plate 37 is pushed to move through the hard contact between the connecting bracket 14 and the drive plate 16, which in turn drives the baffle 36 to move down quickly and block the observation window 23. At this time, the pressure plate 13 begins to apply pressure to the bearing for pressing.
[0047] After the pressing is completed, the pressure cylinder 11 drives the push rod 12 to reset. During the reset process, the elastic force of the second spring 32 pushes the sliding block 35 and the baffle 36 to reset, preparing for the next pressing.
[0048] It should be noted that this utility model is a press-fit bearing fixture. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
