Description

Technical Field

[0001] This application relates to the technical field of bearing disassembly and assembly, and particularly to a gantry bearing disassembly and assembly device. Background Art

[0002] A bearing is a precision component widely used in mechanical equipment. It is mainly used to support a rotating shaft or a swinging shaft, ensure its stable and accurate rotation or swing, and at the same time bear and transmit axial and radial loads. Bearings play a crucial role in mechanical equipment and directly affect the working efficiency, service life, and operating stability of the equipment.

[0003] However, with the operation and use of mechanical equipment, the bearings therein will gradually wear. When the bearings are worn to a certain extent, they can no longer be used and need to be replaced in a timely manner.

[0004] Currently, when replacing bearings, structures such as pullers are mostly used to pull the bearings. However, the bearing and the bearing mounting hole on the bearing housing are in a tight fit, and the hardness of the bearing and the bearing housing is also relatively high. Therefore, it takes a lot of effort to detach the bearing from the bearing mounting hole or install the bearing onto the bearing mounting hole, resulting in troublesome disassembly and assembly of the bearing, and it is also easy to damage the bearing and the bearing housing during the disassembly and assembly process. Summary of the Invention

[0005] In order to improve the convenience during bearing disassembly and assembly and reduce the risk of damage to the bearing and the bearing housing, this application provides a gantry bearing disassembly and assembly device.

[0006] A gantry bearing disassembly and assembly device provided by this application adopts the following technical solutions: A gantry bearing disassembly and assembly device includes a machine body, a placement table, a lifting mechanism, and a disassembly and assembly mechanism. The placement table is slidably arranged up and down on the machine body. The lifting mechanism is used to drive the placement table to move. The disassembly and assembly mechanism includes: A cushion block, which is placed on the placement table and used to support the bearing housing; A mounting member, which is placed on the bearing and used to push the bearing to move to achieve disassembly and assembly of the bearing; A pushing plate, which is slidably arranged up and down on the machine body and used to drive the mounting member to move; A driving assembly, which is used to drive the pushing plate to move.

[0007] By adopting the above technical solution, the bearing seat is placed on the cushion block, so that a sense of space is formed between the bearing seat and the placement table for the bearing to fall. Then, the installation part is placed on the bearing to be disassembled. The lifting mechanism drives the bearing seat and the installation part to move upward and approach the pushing plate. The driving component is activated to drive the pushing plate to move downward. The pushing plate pushes the installation part to move downward, and the installation part pushes the bearing to fall from the bearing installation hole. The lifting mechanism drives the placement table to move downward, and the driving component is activated to drive the pushing plate to move upward. Then, the bearing seat and the bearing can be removed in sequence, thus realizing the disassembly of the bearing.

[0008] When installation is required, the bearing seat is placed on the cushion block, the bearing to be installed is placed on the bearing installation hole of the bearing seat, and the installation part is placed on the bearing. The lifting mechanism and the driving component are activated, so that the bearing seat and the bearing move upward and approach the pushing plate. The pushing plate moves downward to push the installation part and drive the bearing to be installed into the bearing installation hole to complete the installation. The lifting mechanism and the driving component are activated to drive the bearing seat to move downward and the pushing plate to move upward, thereby realizing the installation of the bearing. In this way, the disassembly and assembly of the bearing are realized, the convenience during the disassembly and assembly of the bearing is improved, the disassembly and assembly efficiency of the bearing is increased, and the risk of damage to the bearing and the bearing seat is reduced.

[0009] The lifting mechanism drives the placement table to move and the driving component drives the pushing plate to move, so as to realize relative simultaneous movement, which greatly saves the time spent in the disassembly process. At the same time, different-sized installation parts can be used to adapt to the disassembly and assembly of bearings with different diameters, making it more convenient to realize the disassembly and assembly of bearings of various sizes. Further, the disassembly and assembly efficiency of the bearing is increased, and the risk of damage to the bearing and the bearing seat is reduced.

[0010] Optionally, the driving component includes: A plurality of tension springs, which are arranged on the machine body and connected to the pushing plate and used to keep the pushing plate in an upward movement trend; A hydraulic jack, which is arranged on the pushing plate and the piston rod is pressed against the machine body for positioning under the action of the plurality of tension springs.

[0011] By adopting the above technical solution, the hydraulic jack is shaken to drive its piston rod to extend. The extension of the piston rod drives the pushing plate to move downward and push the installation part to move downward. After the downward movement is completed, the hydraulic jack is unlocked to make its piston rod in a free state. The plurality of tension springs pull the pushing plate to move upward and drive the piston rod of the hydraulic jack to retract, thus realizing the driving of the pushing plate to move. At the same time, the hydraulic jack has a low cost and is easily available, and the hydraulic jack does not require a liquid delivery structure like a hydraulic cylinder, which greatly improves the structural stability and reduces the cost of bearing disassembly and assembly.

[0012] Optionally, the lifting mechanism includes: A lifting lead screw, which is rotatably installed on the machine body and is threadedly connected to the placement table; A rotating component, which is used to drive the lifting lead screw to rotate; A positioning component for positioning the position of the placement table.

[0013] By adopting the above technical solution, when movement is required, the positioning component is unlocked, the rotating component drives the lifting screw rod to rotate, and the rotation of the lifting screw rod drives the placement table to move up and down. After the movement is completed, the positioning component starts to position the placement table.

[0014] Optionally, the rotating component includes: A rotating rod, rotatably mounted on the machine body and in a horizontal state; A rotating disk, arranged on the rotating rod; A first bevel gear and a second bevel gear, respectively arranged on the lifting screw rod and the rotating rod and meshing with each other.

[0015] By adopting the above technical solution, the staff rotates the rotating disk, the rotation of the rotating disk drives the rotating rod and the second bevel gear to rotate, the rotation of the second bevel gear drives the first bevel gear and the lifting screw rod to rotate, so as to drive the lifting screw rod to rotate. At the same time, the cooperation of the first bevel gear and the second bevel gear can also position the lifting screw rod to a certain extent, and the horizontal state of the rotating disk is also convenient for the staff to rotate, thus improving the stability and convenience in the driving process and the disassembly and assembly efficiency of the bearing.

[0016] Optionally, a plurality of positioning holes are vertically spaced on the machine body, and the positioning component includes: A positioning pin, slidably arranged on the placement table and inserted into the positioning hole for positioning; A pull ring, arranged on the positioning pin and facilitating the pulling of the positioning pin to move.

[0017] By adopting the above technical solution, when positioning is required, the pull ring pushes the positioning pin to be inserted into the positioning hole to position the placement table. When the placement table needs to move, the pull ring pulls the positioning pin to disengage from the positioning hole, so as to realize the unlocking and locking of the placement table.

[0018] Optionally, the driving component includes: A guide rod, arranged on the push plate and slidably passing through the machine body; A driving member, connected to the push plate and used to drive the push plate to move By adopting the above technical solution, the driving member drives the push plate to move, and the guide rod is used to guide the movement of the push plate, so as to automatically realize the movement of the push plate.

[0019] Optionally, a positioning member for inserting and mounting on the inner ring of the bearing is arranged on the mounting member, the cushion block is arranged on the machine body and is in a disc shape, the diameter of the cushion block is smaller than the outer diameter of the bearing seat, and a receiving groove is formed on the upper surface and a positioning mechanism for positioning the bearing seat and the bearing is arranged, and the positioning mechanism includes: The positioning plate is arranged on the storage groove in a vertically sliding manner; The elastic member is arranged on the positioning plate, connected to the storage groove, and pushes the positioning plate upward under the action of elastic force; The first positioning post is arranged on the upper surface of the positioning plate and can be inserted into the bearing mounting hole for positioning; The second positioning post is coaxially arranged on the top of the first positioning post and can be inserted into the inner ring of the bearing for positioning; when disassembling the bearing, the bearing seat is placed on the cushion block, and the second positioning post is inserted into the inner ring of the bearing for positioning; when installing the bearing, the bearing seat is placed on the cushion block, and the first positioning post is inserted into the bearing mounting hole and extends above the bearing mounting hole, and then the inner ring of the bearing to be installed is inserted and mounted with the first positioning post for positioning.

[0020] By adopting the above technical solutions, the bearing seat is likely to move during the disassembly and assembly process. A small moving distance will easily cause damage to the bearing and the bearing seat, and a large moving distance will cause the disassembly and assembly of the bearing to fail, thereby prolonging the disassembly and assembly time of the bearing and further increasing the damage to the bearing seat and the bearing, reducing the disassembly and assembly efficiency of the bearing and increasing the risk of damage to the bearing seat and the bearing.

[0021] The cushion block is disc-shaped with a diameter larger than that of the bearing seat and is provided with a storage groove for the bearing to fall into when needed, so as to increase the contact area between the cushion block and the bearing seat while meeting the requirement of the bearing falling, and improve the stability of the bearing during the disassembly and assembly process.

[0022] The cushion block is fixedly installed on the machine body. When the bearing needs to be disassembled, the bearing seat is placed on the cushion block, and the second positioning post is inserted into the inner ring of the bearing to be disassembled for positioning. The first positioning post abuts against the bearing under the elastic force of the elastic member for positioning, so as to realize the positioning of the bearing seat and the bearing. Then, the positioning member on the installation part is inserted into the inner ring of the bearing, and the bottom of the installation part abuts against the bearing for positioning, so as to realize the positioning of the position of the installation part.

[0023] The pushing plate moves downward to push the installation part downward, the installation part moves downward to push the bearing downward, the bearing moves downward to push the second positioning post and the positioning plate downward to compress the elastic member until the bearing falls off the bearing mounting hole. Then, the pushing plate moves upward away from the installation part, and the staff removes the installation part and the bearing seat in sequence. When the bearing seat is removed, it moves away from the second positioning post and the first positioning post, and the elastic member pushes the second positioning post, the first positioning post and the bearing upward, so that the bearing moves upward above the storage groove, and the staff can remove the bearing from the second positioning post.

[0024] When a bearing needs to be installed, place the bearing housing on the cushion block. At this time, the diameter of the bearing installation hole is relatively large, so that the second positioning post passes through the bearing installation hole and extends above the bearing housing, and the first positioning post is inserted into the bearing installation hole for positioning, and the positioning plate abuts against the bearing housing for positioning, so as to realize the positioning of the bearing housing and the bearing. Bring the bearing to be installed close to the first positioning post, so that the first positioning post is inserted into the inner ring of the bearing for positioning, and then the positioning member on the installation part is inserted into the inner ring of the bearing, and the bottom of the installation part abuts against the bearing for positioning. The push plate moves downward to push the installation part to move, so that the bearing is installed into the bearing installation hole, so as to realize the disassembly and assembly of the bearing.

[0025] Through the above structure, the bearing housing and the bearing can be positioned during both disassembly and installation, reducing the probability of displacement of the bearing housing and the bearing. When the positioning plate, the first positioning post and the second positioning post move vertically, they can also guide the bearing during disassembly and installation, reducing the risk of displacement of the bearing during the disassembly and installation process. At the same time, it also makes the placement of the bearing housing and the installation of the bearing more convenient during the disassembly and assembly of the bearing. The second positioning post can also catch the bearing, reducing the risk of damage to the machine body and the bearing when the bearing falls on the machine body. Therefore, the disassembly and assembly efficiency of the bearing is further improved and the risk of damage to the bearing housing and the bearing is reduced.

[0026] Optionally, a positioning block is provided on the installation part and is inserted and installed on the second positioning post for positioning.

[0027] By adopting the above technical solution, after the positioning member is inserted and installed on the inner ring of the bearing, the positioning block is inserted and installed on the second positioning post for positioning, so as to be able to guide the installation part during movement, reducing the risk of displacement of the installation part and further reducing the risk of damage to the bearing housing and the bearing.

[0028] Optionally, the installation part includes an installation section and a pressing section arranged coaxially. The installation section is used to be placed on the bearing and has a diameter smaller than that of the pressing section.

[0029] By adopting the above technical solution, the contact area with the push plate is increased, and the stability during the disassembly and assembly of the bearing is improved.

[0030] Optionally, the installation part is detachably arranged on the push plate through a connecting component. The connecting component includes: Two connecting blocks, which are arranged to slide towards each other on the push plate; A connecting screw, which passes through the two connecting blocks and is threadedly connected with a nut for fixing, so that the two connecting blocks are clamped on the installation section and the pressing section for positioning.

[0031] By adopting the above technical solution, the pressing section is abutted against the pushing plate, then the two connecting blocks are abutted against each other, the connecting screw is passed through the two connecting blocks, and the nut is threadedly connected to the connecting screw to fix the two connecting blocks, so that the two connecting blocks are clamped on the mounting section and the pressing section for positioning. In this way, the mounting part can be mounted on the pushing plate without manual placement of the mounting part, improving the disassembly efficiency of the bearing and enabling the replacement of different mounting parts according to requirements.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. The disassembly and assembly of the bearing are realized through the mounting part, the pushing plate, the lifting mechanism and the driving component, improving the convenience during the disassembly and assembly of the bearing and reducing the risk of damage to the bearing seat and the bearing. Moreover, the lifting mechanism drives the placement table to move and the driving component drives the pushing plate to move, thus realizing relative simultaneous movement, greatly saving the time spent in the disassembly process. At the same time, different-sized mounting parts can be used to adapt to the disassembly and assembly of bearings with different diameters, making it more convenient to realize the disassembly and assembly of bearings of various sizes, further improving the disassembly and assembly efficiency of the bearing and reducing the risk of damage to the bearing and the bearing seat.

[0033] 2. Through the above structure, the bearing seat and the bearing can be positioned both during disassembly and installation, reducing the probability of displacement of the bearing seat and the bearing. When the positioning plate, the first positioning column and the second positioning column move vertically, they can also guide the disassembly and installation of the bearing, reducing the risk of displacement of the bearing during the disassembly and installation process. At the same time, it also makes it more convenient to place the bearing seat and install the bearing during the disassembly and assembly of the bearing. The second positioning column can also catch the bearing, reducing the risk of damage to the machine body and the bearing when the bearing falls on the machine body. Therefore, the disassembly and assembly efficiency of the bearing is further improved and the risk of damage to the bearing seat and the bearing is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following further elaborates on this application in detail.

[0037] The embodiment of this application discloses a gantry bearing disassembly and assembly device.

[0038] Embodiment 1 Referring to Figure 1 , the gantry bearing disassembly and assembly device includes a machine body 1, a placing table 11, a lifting mechanism 2 and a disassembly and assembly mechanism 4. The placing table 11 is vertically slidably installed on the machine body 1 and is used for placing a bearing seat. The lifting mechanism 2 is used to drive the placing table 11 to move, and the disassembly and assembly mechanism 4 is used to realize the disassembly and installation of the bearing on the bearing seat.

[0039] An installation hole for the machine body 1 to pass through is formed on the placing table 11, so that the placing table 11 is vertically slidably installed on the machine body 1. Support wheels 12 that abut against the opposite side walls of the machine body 1 are rotatably installed on the upper surfaces at both ends in the length direction of the placing table 11, thereby reducing the friction between the placing table 11 and the machine body 1.

[0040] Referring to Figure 1 and Figure 2 , the lifting mechanism 2 includes a lifting screw rod 21, a rotating assembly 22 and a positioning assembly 3. The lifting screw rod 21 is rotatably installed on the side wall of the machine body 1 and is in a vertical state. Two lifting screw rods 21 are arranged at intervals and are respectively threadedly connected to both ends of the placing table 11. The two lifting screw rods 21 rotate to drive the placing table 11 to move vertically. The rotating assembly 22 is used to drive the two lifting screw rods 21 to rotate simultaneously. The rotating assembly 22 includes a rotating rod 23, a rotating disc 24, a bevel gear one 25 and a bevel gear two 26. The rotating rod 23 is horizontally rotatably installed on the top of the machine body 1 and both ends pass through above the lifting screw rods 21; the rotating disc 24 is coaxially and fixedly installed on the rotating rod 23.

[0041] There are two bevel gears one 25, which are respectively key-connected to the top of the lifting screw rod 21. There are two bevel gears two 26, which are spaced apart and key-connected to the rotating rod 23. The two bevel gears two 26 are correspondingly arranged with the two bevel gears one 25 and mesh with each other. The staff rotates the rotating disk 24, and the rotation of the rotating disk 24 drives the rotation of the rotating rod 23 and the two bevel gears two 26. The rotation of the bevel gear two 26 drives the rotation of the bevel gear one 25 and the lifting screw rod 21, so as to drive the vertical movement of the placing table 11.

[0042] Referring to Figure 1 and Figure 3 On the machine body 1 and at both ends of the placing table 11, a plurality of positioning holes 13 are vertically spaced. The positioning assembly 3 includes a positioning pin 31 and a pull ring 32. The positioning pin 31 horizontally slides through the side wall of the placing table 11 and is inserted into the positioning hole 13 for positioning. The pull ring 32 is fixedly installed on the positioning pin 31 to facilitate driving the movement of the positioning pin 31.

[0043] The disassembly and assembly mechanism 4 includes cushion blocks 41, mounting parts 42, a pushing plate 43, and a driving assembly 5. There are multiple cushion blocks 41, which are strip-shaped. The multiple cushion blocks 41 are in a horizontal state and placed on the upper surface of the placing table 11. The bearing seat is placed on the multiple cushion blocks 41, so that a space for the bearing to fall is formed between the bearing seat and the placing table 11. The mounting part 42 includes a coaxially connected mounting section 44 and a pressing section 45. The diameter of the mounting section 44 is smaller than that of the pressing section 45. The diameter of the mounting section 44 is smaller than the outer diameter of the bearing to be disassembled and larger than the inner diameter of the bearing to be disassembled. The mounting section 44 is placed on the bearing to be disassembled, so that the bearings of the mounting section 44 and the bearing to be disassembled coincide.

[0044] The pushing plate 43 is vertically slidably installed on the machine body 1, and the pushing plate 43 is located above the placing table 11. The pushing plate 43 moves downward and abuts against the pressing section 45. When the pushing plate 43 continues to move downward, it pushes the mounting section 44 and the bearing downward, so that the bearing falls from the bearing mounting hole of the bearing seat.

[0045] The driving assembly 5 includes a plurality of tension springs 51 and a hydraulic jack 52. There are two groups of the plurality of tension springs 51 spaced apart and located at both ends of the pushing plate 43. Each group of tension springs 51 has two spaced apart and located on both sides of the pushing plate 43. On the machine body 1 and at the top of the tension spring 51, a fixing column one 53 is provided. At both ends of the pushing plate 43 and at the position of the tension spring 51, fixing columns two 54 are fixedly installed. Both ends of the tension spring 51 are hooked on the fixing column one 53 and the fixing column two 54, and drive the pushing plate 43 to maintain an upward trend. The bottom of the hydraulic jack 52 is fixedly installed on the upper surface of the pushing plate 43 through screws. The piston rod of the hydraulic jack 52 is vertically upward and is positioned by abutting against the machine body 1 under the action of the spring.

[0046] The rocking hydraulic jack 52 drives the elongation of its piston rod, thereby driving the pushing plate 43 to move downward. The pushing plate 43 abuts against the pressing section 45. The pushing plate 43 continues to move downward to disengage the bearing from the bearing mounting hole, thereby realizing the disassembly of the bearing. Then, the hydraulic jack 52 is unlocked, and the pushing plate 43 moves upward under the pulling force of multiple tension springs 51. The upward movement of the pushing plate 43 drives the piston rod of the hydraulic jack 52 to retract, thereby realizing the vertical movement of the pushing plate 43.

[0047] The working principle of the embodiment of the present application is as follows: Place the bearing seat on multiple cushion blocks 41, then place the mounting section 44 on the bearing and align it with the bearing. Pull the pull ring 32 to drive the positioning pin 31 to disengage from the positioning hole 13. Rotate the rotating disk 24 to drive the placement table 11, the cushion blocks 41, the bearing seat, and the mounting member 42 to move upward. After reaching the position, the rotating disk 24 stops rotating. Push the pull ring 32 to insert the positioning pin 31 into the positioning hole 13 for positioning. At the same time, the hydraulic jack 52 drives the pushing plate 43 to move downward. The downward movement of the pushing plate 43 drives the mounting member 42 to move downward to push the bearing, so that the bearing falls from the bearing mounting hole onto the placement table 11. Unlock the hydraulic jack 52, and the pushing plate 43 moves upward under the pulling force of the tension spring 51. Then, remove the mounting member 42, the bearing seat, and the disassembled bearing in sequence. Then, drive the placement table 11 to move downward, thereby realizing the disassembly of the bearing.

[0048] When installing the bearing, place the bearing seat on multiple cushion blocks 41, then place the bearing to be installed on the bearing mounting hole, place the mounting section 44 on the bearing. The placement table 11 moves upward and the pushing plate 43 moves downward, so that the bearing is snap-fitted into the bearing mounting hole. The placement table 11 moves downward and the pushing plate 43 moves upward, thereby realizing the installation of the bearing. Therefore, the disassembly and installation efficiency of the bearing is improved, and the risk of damage to the bearing and the bearing seat is reduced.

[0049] Embodiment 2 Refer to Figure 1 and Figure 4 In this embodiment, the difference from Embodiment 1 is that the driving assembly 5 includes a guide rod 81 and a driving member 82. A plurality of guide rods 81 are spaced apart and fixedly installed on the upper surface of the pushing plate 43. The guide rod 81 slidably penetrates through the machine body 1 and guides the movement of the pushing plate 43 when it moves; the driving member 82 is an electric push rod or a hydraulic rod. The driving member 82 is fixedly installed on the upper surface of the machine body 1, and the piston rod of the driving member 82 passes through the machine body 1 and is fixedly connected to the upper surface of the pushing plate 43; the driving member 82 drives the pushing plate 43 to move, so that manual control is not required, further improving the disassembly and installation efficiency of the bearing.

[0050] The mounting member 42 is detachably arranged on the pushing plate 43 through the connecting assembly 6. The connecting assembly 6 includes two connecting blocks 61 and a connecting screw 62. The two connecting blocks 61 are arranged to slide towards each other horizontally on the lower surface of the pushing plate 43. The connecting screw 62 passes through the two connecting blocks 61, and a nut that presses against the connecting block 61 is threadedly connected to the connecting screw 62, so that the two connecting blocks 61 press against the mounting section 44 and the pressing section 45 for positioning, thereby fixing the two connecting blocks 61 to realize the fixed installation of the mounting member 42 on the pushing plate 43.

[0051] The working principle of the embodiment of the present application is as follows: The driving member 82 drives the pushing plate 43 to move, and the pushing plate 43 drives the mounting member 42 to move, so that there is no need for manual operation to drive the pushing plate 43 to move. At the same time, turn the nut away from the connecting block 61, and then the mounting member 42 can be replaced. Turn the nut so that the two connecting blocks 61 press against the mounting section 44 and the pressing section 45 for positioning, so that mounting members 42 of different sizes can be replaced to adapt to bearings of different sizes, further improving the disassembly and assembly efficiency of the bearings, and reducing the risk of the position of the mounting member 42 changing, and reducing the risk of damage to the bearings and the bearing seats.

[0052] Embodiment Three Refer to Figure 1 and Figure 5 In this embodiment, the difference from Embodiment 1 is that the cushion block 41 is disc-shaped and has a diameter larger than the diameter of the bearing seat. A receiving groove 48 is coaxially opened on the upper surface of the cushion block 41. The cushion block 41 is fixedly installed on the placing table 11 through a screw and is provided with a positioning mechanism 7 for positioning the bearing seat and the bearing.

[0053] Refer to Figure 5 and Figure 6 In this embodiment, the positioning mechanism 7 includes a positioning plate 71, an elastic member 72, a first positioning post 73 and a second positioning post 74. The positioning plate 71 is disc-shaped and its outer circumferential surface abuts against the receiving groove 48 and is vertically slidably installed in the receiving groove 48. The elastic member 72 is a spring or a spring sheet. The elastic member 72 is fixedly installed on the lower surface of the positioning plate 71, and the bottom end of the elastic member 72 presses against the bottom of the receiving groove 48. The elastic member 72 is used to drive the positioning plate 71 to maintain an upward movement trend.

[0054] The positioning post one 73 is coaxially and fixedly installed on the upper surface of the positioning plate 71. The positioning post two 74 is coaxially and fixedly installed on the top of the positioning post one 73. The diameter of the positioning post one 73 is not greater than the diameter of the bearing mounting hole, so that the positioning post one 73 can be inserted into the bearing mounting hole for positioning. The diameter of the positioning post two 74 is not greater than the inner diameter of the bearing, so that the positioning post two 74 can be inserted into the inner ring of the bearing for positioning. A positioning groove 75 is formed on the top of the positioning post two 74. At the bottom of the installation section 44, a positioning member 46 is coaxially arranged and inserted into the inner ring of the bearing for positioning. At the same time, a positioning block 47 is fixedly installed at the bottom of the positioning member 46 and inserted into the positioning groove 75 for positioning.

[0055] Referring to Figure 1 、 Figure 5 and Figure 6 , when disassembling the bearing, place the bearing seat on the cushion block 41, so that the positioning post two 74 is inserted into the inner ring of the bearing for positioning, and the bearing to be disassembled presses the positioning post one 73 and the positioning post two 74 to move downward, so that the positioning post one 73 presses against the bearing to be disassembled under the action of the elastic member 72 for positioning. Then insert the positioning member 46 into the inner ring of the bearing to be disassembled for positioning, and insert the positioning block 47 into the positioning groove 75 for positioning, so as to be able to position the position of the installation member 42. Push the push plate 43 downward to push the installation member 42 downward to push the bearing to fall off the installation hole. During this process, the bearing pushes the positioning post one 73 and the positioning post two 74 downward to squeeze the elastic member 72.

[0056] Move the push plate 43 upward away from the installation member 42. The elastic member 72 pushes the dropped bearing under the action of the elastic force to press against the lower surface of the bearing seat, that is, the orifice of the bearing installation hole for positioning. Remove the installation member 42 and the bearing seat in sequence. The bearing seat moves away from the positioning post one 73 and the positioning post two 74. The elastic member 72 pushes the positioning post one 73, the positioning post two 74 and the bearing upward, so that the bearing moves upward above the storage groove 48, and the positioning plate 71 is still located in the storage groove 48. Then the bearing can be removed from the positioning post two 74, thus realizing the disassembly of the bearing.
