Technical Field
[0001] This utility model relates to the field of bearing installation technology, specifically a bearing assembly installation device. Background Technology
[0002] Bearings are an essential component in modern machinery. Their primary function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Bearings are a crucial connecting component in mechanical transmission, and their quality directly impacts machine efficiency. Bearing assembly installation devices are specialized tools or equipment used to accurately and efficiently install bearings (including inner rings, outer rings, rolling elements, cages, etc.) into journals or bearing housings.
[0003] Chinese utility model patent CN220240604U discloses a bearing installation device, including a base, a support plate fixedly installed at the upper center of the base, a processing table fixedly installed at the upper center of the support plate, a circular storage area in the inner center of the processing table, a clamping assembly in the inner center of the storage area, the clamping assembly including three sets of arc-shaped clamping blocks arranged in a triangular pattern, a first telescopic rod in the back center of the clamping blocks, the base of the first telescopic rod fixedly installed in the inner center of the processing table, a three-jaw chuck in the upper center of the processing table, a cylinder in the top center of the three-jaw chuck, and four sets of support blocks in the inner center of the support plate, the support blocks being located at the bottom center of the clamping assembly. It uses a clamping assembly to clamp and position the bearing, thereby enabling rapid installation between the shaft and the bearing. By adjusting the size of the through hole, it can install and connect bearings and shafts of different sizes. However, this existing bearing installation device lacks a buffer device. When the three-jaw chuck drives the shaft to install the bearing held by the clamping assembly, a large impact force is generated at the moment of contact between the shaft and the bearing, which can cause damage to the bearing.
[0004] Therefore, this utility model provides a bearing assembly mounting device to solve the above problems. Utility Model Content
[0005] This utility model provides a bearing assembly installation device, which aims to solve the problems mentioned in the background art, such as the lack of a buffer device in the existing bearing installation device, the large collision force generated at the moment of contact between the shaft and the bearing when the three-jaw chuck drives the shaft to install the bearing held by the clamping assembly, which can cause damage to the bearing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing assembly installation device, including an installation plate, on which buffer structures and vertical rods are symmetrically installed, the upper ends of two sets of buffer structures are connected by a workbench, the upper ends of two sets of vertical rods are connected by a top plate, a cylinder is installed on the end face of the top plate, a moving plate is provided on the drive rod of the cylinder, and a three-jaw chuck is installed at the bottom of the moving plate;
[0007] The buffer structure includes two sets of fixed plates symmetrically mounted on the end faces of the mounting plate. Crossbars are installed on the corresponding side walls of the two sets of fixed plates. Springs and two sets of sliding sleeves are sleeved on the outer walls of the fixed plates, located on both the front and rear sides. A U-shaped plate is rotatably mounted on the rear sliding sleeve. A second connecting frame connected to the bottom of the worktable is rotatably mounted on the other end of the U-shaped plate. A T-shaped rod is rotatably mounted on the rear sliding sleeve. By setting up the buffer structure, the collision force of the shaft and bearing upon instantaneous contact is buffered and absorbed, thus protecting the bearing during the installation process. This avoids the problem of existing bearing installation devices lacking buffer devices, where a large collision force is generated at the moment of contact between the shaft and bearing when the three-jaw chuck drives the shaft to install the bearing held by the clamping assembly, potentially causing bearing damage. This improves the performance of the bearing assembly installation device.
[0008] Preferably, the end face of the workbench is equipped with a straightening structure;
[0009] The straightening structure includes an L-shaped plate installed on the end face of the workbench, and a horizontal plate installed on the other end of the L-shaped plate corresponding to the three-jaw chuck, with straightening holes provided on the horizontal plate.
[0010] Preferably, a second through hole is provided at the center of the end face of the workbench, a support plate is installed on the end face of the workbench, a telescopic rod is installed on the side wall of the support plate, a clamp is provided on the drive rod of the telescopic rod, and at least three sets of support plates are provided, which are distributed in a ring array on the end face of the workbench.
[0011] Preferably, the bottom of the workbench is symmetrically equipped with stepped rods, and the mounting plate is symmetrically provided with first through holes. The mounting plate is slidably connected to the lower outer wall of the stepped rods through the first through holes.
[0012] Preferably, a first connecting frame is installed on the end face of the sliding sleeve, the front sliding sleeve is rotatably connected to the T-shaped rod through the front first connecting frame, the rear sliding sleeve is rotatably connected to the U-shaped plate through the rear first connecting frame, and the other end of the T-shaped rod is rotatably connected to the second connecting frame through a connecting hole.
[0013] Preferably, the movable plate has symmetrically provided third through holes, the movable plate is slidably connected to the vertical rod through the third through holes, and a support leg is installed at the bottom corner of the mounting plate.
[0014] Preferably, ear plates are symmetrically installed on the front and rear side walls of the L-shaped plate, and bolts are installed on the ear plates through connecting holes. Threaded holes are opened on the side walls of the horizontal plate corresponding to the bolts.
[0015] Beneficial effects: By setting up a buffer structure and using a combination of fixed plates, springs, sliding sleeves, U-shaped plates, and T-shaped rods, the collision force of the shaft and bearing upon instantaneous contact is buffered and absorbed. This protects the bearing during the installation process and avoids the problem of existing bearing installation devices lacking buffer devices. When the three-jaw chuck drives the shaft to install the bearing held by the clamping assembly, a large collision force is generated at the moment of contact between the shaft and the bearing, which can cause damage to the bearing. Therefore, the bearing assembly installation device performs better. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] This embodiment provides a bearing assembly mounting device, such as... Figure 1-6 As shown, the bearing assembly mounting device includes a mounting plate 1. A buffer structure 2 and a vertical rod 4 are symmetrically mounted on the end face of the mounting plate 1. The upper ends of the two sets of buffer structures 2 are connected through a workbench 3. The upper ends of the two sets of vertical rods 4 are connected through a top plate 5. A cylinder 6 is mounted on the end face of the top plate 5. A moving plate 7 is provided on the drive rod of the cylinder 6. A three-jaw chuck 8 is mounted on the bottom of the moving plate 7.
[0026] The buffer structure 2 includes two sets of fixed plates 21 symmetrically installed on the end face of the mounting plate 1. The corresponding side walls of the two sets of fixed plates 21 are equipped with crossbars 22. The outer walls of the fixed plates 21 and the front and rear sides are fitted with springs 23 and two sets of sliding sleeves 24 slidably installed on the outer walls of the fixed plates 21. The rear sliding sleeve 24 is rotatably installed with a U-shaped plate 25. The other end of the U-shaped plate 25 is rotatably installed with a second connecting frame 26. The rear sliding sleeve 24 is rotatably installed with a T-shaped rod 27.
[0027] In use, the upper end of the shaft is fixed by the three-jaw chuck 8, and multiple sets of telescopic rods 10 drive multiple sets of bearings to be fixed on the worktable 3. The cylinder 6 drives the moving plate 7 to move downward, and the moving plate 7 moves the three-jaw chuck 8 downward. The three-jaw chuck 8 drives the shaft to move downward, and the lower end of the shaft contacts the inner wall of the bearing inner ring and generates a large impact force instantaneously. The bearing is subjected to force and transmitted to the worktable 3. The worktable 3 transmits force to the two sets of second connecting frames 26 and drives the second connecting frames 26 to move downward. The second connecting frames 26 drive the U-shaped plate 25 and T-shaped rod 27 to move. The U-shaped plate 25 and T-shaped rod 27 are on the front and rear sets of first connecting frames 241. While rotating, the first connecting frame 241 is driven to move towards the fixed plate 21. The two sets of first connecting frames 241 drive the two sets of sliding sleeves 24 to compress the two sets of springs 23. Thus, the springs 23 can buffer and absorb the collision force when the shaft and bearing come into contact at the moment of contact. This protects the bearing during the installation of the shaft and bearing, avoiding the lack of buffering devices in existing bearing installation devices. When the three-jaw chuck drives the shaft and the bearing held by the clamping assembly to install, a large collision force will be generated at the moment of contact between the shaft and the bearing, which will cause damage to the bearing. This makes the bearing assembly installation device more effective.
[0028] In this embodiment, a second through hole 31 is provided at the center of the end face of the workbench 3, a support plate 9 is installed on the end face of the workbench 3, a telescopic rod 10 is installed on the side wall of the support plate 9, a clamping plate 11 is provided on the drive rod of the telescopic rod 10, and at least three sets of support plates 9 are provided, which are distributed in a ring array on the end face of the workbench 3; a stepped rod 13 is symmetrically installed at the bottom of the workbench 3, and a first through hole 101 is symmetrically provided on the mounting plate 1, and the mounting plate 1 is slidably connected to the lower outer wall of the stepped rod 13 through the first through hole 101.
[0029] The stepped rod 13 and the first through hole 101 serve two purposes: firstly, they guide the downward pressing of the two sets of buffer structures 2 by the worktable 3, thus limiting the movement trajectory of the worktable 3; secondly, the upper shaft diameter of the stepped rod 13 is larger than the lower shaft diameter, and the diameter of the first through hole 101 is matched with the lower shaft diameter of the stepped rod 13. After the spring 23 buffers the collision force, the worktable 3 drives the stepped rod 13 to move down a certain distance and then fixes it, providing a static environment for the installation of the shaft and bearing, making it convenient for the shaft to slide onto the inner wall of the bearing inner ring, thus completing the bearing installation.
[0030] In this embodiment, a first connecting frame 241 is installed on the end face of the sliding sleeve 24. The front sliding sleeve 24 is rotatably connected to the T-shaped rod 27 through the front first connecting frame 241. The rear sliding sleeve 24 is rotatably connected to the U-shaped plate 25 through the rear first connecting frame 241. The other end of the T-shaped rod 27 is rotatably connected to the second connecting frame 26 through the connecting hole. A third through hole 71 is symmetrically opened on the moving plate 7. The moving plate 7 is slidably connected to the vertical rod 4 through the third through hole 71. A support leg 14 is installed at the bottom corner of the mounting plate 1.
[0031] Example 2
[0032] Unlike Embodiment 1, the existing bearing mounting device does not have a function to straighten the shaft when the drive shaft moves down to the bearing mounting position, which may cause the shaft to be installed at an angle, increasing the difficulty of bearing installation. Therefore, a straightening structure 12 is installed on the end face of the workbench 3.
[0033] The straightening structure 12 includes an L-shaped plate 121 installed on the end face of the workbench 3, and a horizontal plate 122 installed on the other end of the L-shaped plate 121 and corresponding to the three-jaw chuck 8. A straightening hole 1221 is provided on the horizontal plate 122.
[0034] In use, the three-jaw chuck 8 drives the shaft to move downwards, and the lower end of the shaft passes through the straightening hole 1221. During the process of the shaft passing through the straightening hole 1221, it is straightened by the horizontal plate 122, so that the shaft center is aligned with the inner wall center of the bearing. This makes it easier for the shaft to move downwards and slide onto the inner wall of the bearing inner ring. This avoids the problem that existing bearing installation devices do not have a straightening function when driving the shaft downwards to install the bearing, which may cause the shaft to be installed at an angle, increasing the difficulty of bearing installation. This provides convenience for the installation of bearings and shafts, making the bearing assembly installation device more effective.
[0035] In this embodiment, ear plates 1211 are symmetrically installed on the front and rear side walls of the L-shaped plate 121. Bolts 123 are installed on the ear plates 1211 through the connecting holes. Threaded holes 1222 are opened on the side walls of the horizontal plate 122 corresponding to the bolts 123.
[0036] The device uses ear plate 1211, bolt 123 and threaded hole 1222 in combination. By removing bolt 123 from threaded hole 1222, the installed cross plate 122 can be removed. Cross plates 122 with different sizes of straightening holes 1221 can be replaced to achieve the installation of bearings with different sizes of shaft diameters, thereby improving the flexibility of bearing assembly installation device.
[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
