Technical Field

[0001] The utility model relates to the technical field of spherical bearings, in particular to an assembly device for spherical bearings. Background Art

[0002] Spherical plain bearings are a type of spherical sliding bearings whose sliding contact surfaces are an inner sphere and an outer sphere. They can rotate and swing at any angle during movement. They are made using a variety of special processing methods such as surface phosphating, blasting, padding, and spraying.

[0003] A Chinese patent discloses an assembly device for rod-end joint bearings (authorization announcement number CN218325851U). This patented technology sets a positioning sleeve structure so that the lower end rod can fit on the inner side of a semicircular positioning plate, which can be positioned and guided during crimping to facilitate crimping positioning.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing spherical joint bearing is assembled by placing the outer ring of the spherical joint bearing on a table, and pressing the inner ring of the spherical joint bearing into the inner ring of the outer ring through a hydraulic device. At the moment when the inner ring enters the outer ring, the opening of the outer ring will quickly rebound and close, and at the same time generate violent vibrations, causing the entire spherical joint bearing to be displaced, which may cause damage to surrounding personnel or objects. Utility Model Content

[0005] The technical problem to be solved by the present invention is that in the prior art, the opening of the outer ring will quickly rebound and close at the moment the inner ring enters the outer ring, generating violent vibrations, causing the entire joint bearing to be displaced, which may cause damage to surrounding personnel or objects. For this reason, we propose an assembly device for joint bearings.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: an assembly device for a spherical bearing, comprising a workbench, support plates are fixedly connected to both sides of the bottom of the workbench, an L-shaped frame is fixedly connected to the top of the workbench, a hydraulic device is installed on the top of the L-shaped frame, a pressure plate is fixedly connected to the bottom of the hydraulic device, a control button is installed on the top of the workbench, two hollow blocks are fixedly connected to the top of the workbench, and the outer ring of the spherical bearing is fitly connected to the top of the workbench;

[0007] A clamping mechanism for clamping the outer ring of the spherical bearing is installed inside the hollow block.

[0009] Preferably, one side of the clamping plate is in contact with the outer wall of the outer ring of the spherical plain bearing, and the protruding length of the clamping plate is smaller than the thickness of the outer ring of the spherical plain bearing.

[0010] Preferably, one end of the clamping plate is fixedly connected to a pull rod, a limiting groove is provided on the top of the pull rod, one side of the hollow block is fixedly connected to a fixed block, and an L-shaped limiting plate is slidably connected inside the fixed block.

[0014] Technical effects and advantages of this utility model:

[0015] In the utility model, the hydraulic device is activated by a control button to push the pressure plate to press the inner ring of the joint bearing into the interior of the outer ring of the joint bearing.

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0024] Reference Figure 1 - Figure 3 As shown, the utility model provides a technical solution: an assembly device for a joint bearing, comprising a workbench 1, support plates 2 are fixedly connected to both sides of the bottom of the workbench 1, an L-shaped frame 3 is fixedly connected to the top of the workbench 1, a hydraulic device 4 is installed on the top of the L-shaped frame 3, a pressure plate 5 is fixedly connected to the bottom of the hydraulic device 4, a control button 6 is installed on the top of the workbench 1, two hollow blocks 7 are fixedly connected to the top of the workbench 1, a joint bearing outer ring 17 is fitted on the top of the workbench 1, a clamping mechanism for clamping the joint bearing outer ring 17 is installed inside the hollow block 7, the clamping mechanism includes a clamping plate 8 slidably connected to the inside of the hollow block 7, one end of the clamping plate 8 is fixedly connected to a thrust spring 9, and the other end of the thrust spring 9 is fixedly connected to one side of the inside of the hollow block 7. When the user needs to assemble the joint bearing, he first moves the clamping plate 8 to both sides to tighten the joint bearing outer ring The ring 17 is placed in the middle of the clamping plate 8, the clamping plate 8 is released, and the clamping plate 8 is pushed to clamp the outer ring 17 of the joint bearing under the thrust of the thrust spring 9, and the inner ring of the joint bearing is placed above the outer ring 17 of the joint bearing. The hydraulic device 4 is started by the control button 6 to push the pressure plate 5 to press the inner ring of the joint bearing into the interior of the outer ring 17 of the joint bearing. In the process of the inner ring of the joint bearing being pressed into the outer ring 17 of the joint bearing, the cutout of the outer ring 17 of the joint bearing opens to both sides. In the process of the outer ring 17 of the joint bearing opening, the clamping plate 8 is pushed to move to both sides, squeezing the thrust spring 9. When the inner ring of the joint bearing enters the interior of the outer ring 17 of the joint bearing, the outer ring 17 of the joint bearing rebounds. At the same time, the thrust spring 9 pushes the clamping plate 8 and the outer ring 17 of the joint bearing to move at the same time to prevent the vibration of the rebound of the outer ring 17 of the joint bearing from causing splashing and damaging nearby equipment or injuring nearby personnel.

[0025] Reference Figure 1 and Figure 2As shown, in this embodiment: one side of the clamping plate 8 is in contact with the outer wall of the spherical bearing outer ring 17, and the protruding length of the clamping plate 8 is less than the thickness of the spherical bearing outer ring 17. By setting the inner side of the clamping plate 8 to be in contact with the outer wall of the spherical bearing outer ring 17, the clamping of the spherical bearing outer ring 17 can be more stable. At the same time, the protruding position of the clamping plate 8 can prevent the spherical bearing outer ring 17 from flying upward. Since the protruding distance of the clamping plate 8 is less than the rear end of the spherical bearing outer ring 17, the clamping plate 8 can be prevented from obstructing the inner ring of the spherical bearing.

[0026] Reference Figure 3 As shown, in this embodiment: one end of the clamping plate 8 is fixedly connected to a pull rod 16, and a limiting groove 10 is provided on the top of the pull rod 16. One side of the hollow block 7 is fixedly connected to a fixed block 11, and the internal sliding connection of the fixed block 11 is an L-shaped limiting plate 12. The user pulls the pull rod 16 to drive the clamping plate 8 to move to both sides. When the clamping plate 8 moves to the position of the L-shaped limiting plate 12, the L-shaped limiting plate 12 is moved downward to enter the limiting groove 10 to limit the position of the clamping plate 8, so that the user can free both hands to take the outer ring 17 of the joint bearing. After placing the outer ring 17 of the joint bearing on the inner side of the clamping plate 8, the L-shaped limiting plate 12 is moved upward to release the limit on the clamping plate 8, and the thrust spring 9 pushes the clamping plate 8 to clamp the outer ring 17 of the joint bearing.

[0027] Reference Figure 3 As shown, in this embodiment: the top of the fixed block 11 is fixedly connected with a tension spring 13, and the top of the tension spring 13 is fixedly connected to one side of the L-shaped limiting plate 12. When the user needs to place the outer ring 17 of the joint bearing in the middle of the clamping plate 8, the pull rod 16 is pulled to both sides. When the limiting groove 10 on the pull rod 16 moves to the position of the L-shaped limiting plate 12, the tension spring 13 pulls the L-shaped limiting plate 12 downward and enters the inside of the limiting groove 10 to limit the clamping plate 8, so that the user can free up both hands to take the outer ring 17 of the joint bearing.

[0028] Reference Figure 4 and Figure 5 As shown, in this embodiment: limiting grooves 14 are provided on both sides of the interior of the hollow block 7, and limiting sliders 15 are fixedly connected on both sides of the clamping plate 8. During the movement of the clamping plate 8, the limiting sliders 15 on both sides of the clamping plate 8 move inside the limiting grooves 14 to limit the movement of the clamping plate 8, thereby preventing the clamping plate 8 from tilting and causing movement jamming.

[0029] Reference Figure 6As shown, in this embodiment: two placement grooves 18 are provided at the bottom of the clamping plate 8, and pulleys 19 are installed inside the placement grooves 18. During the movement of the clamping plate 8, the pulleys 19 at the bottom of the clamping plate 8 rotate along with the movement of the clamping plate 8, reducing the friction between the bottom of the clamping plate 8 and the top of the workbench 1, making the movement and replacement of the clamping plate 8 smooth, and preventing the bottom of the clamping plate 8 from being worn.

[0030] Working principle: When the user needs to assemble the spherical plain bearing, first move the clamping plate 8 to both sides, put the outer ring 17 of the spherical plain bearing in the middle of the clamping plate 8, loosen the clamping plate 8, and push the clamping plate 8 to clamp the outer ring 17 of the spherical plain bearing under the thrust of the thrust spring 9, put the inner ring of the spherical plain bearing on the top of the outer ring 17 of the spherical plain bearing, start the hydraulic device 4 through the control button 6, and push the pressure plate 5 to press the inner ring of the spherical plain bearing into the inside of the outer ring 17 of the spherical plain bearing. In the process of the inner ring of the spherical plain bearing being pressed into the outer ring 17 of the spherical plain bearing, the cutting of the outer ring 17 of the spherical plain bearing is completed. The mouth opens to both sides. In the process of the joint bearing outer ring 17 opening, the clamping plate 8 is pushed to move to both sides, squeezing the thrust spring 9. When the inner ring of the joint bearing enters the interior of the joint bearing outer ring 17, the joint bearing outer ring 17 rebounds. At the same time, the thrust spring 9 pushes the clamping plate 8 and the joint bearing outer ring 17 to move at the same time. By setting the inner side of the clamping plate 8 to fit the outer wall of the joint bearing outer ring 17, the clamping of the joint bearing outer ring 17 can be more stable. At the same time, the protruding position of the clamping plate 8 can prevent the joint bearing outer ring 17 from flying upward. The protruding distance of 8 is smaller than the rear end of the outer ring 17 of the joint bearing, which can prevent the clamping plate 8 from obstructing the inner ring of the joint bearing. Pulling the pull rod 16 drives the clamping plate 8 to move to both sides. When the clamping plate 8 moves to the position of the L-shaped limit plate 12, the L-shaped limit plate 12 is moved downward to enter the limit groove 10 to limit the position of the clamping plate 8, so that the user can free both hands to pick up the outer ring 17 of the joint bearing. After placing the outer ring 17 of the joint bearing on the inner side of the clamping plate 8, the L-shaped limit plate 12 is moved upward to release the limit on the clamping plate 8, and the thrust spring 9 pushes the clamping plate 8. To clamp the outer ring 17 of the joint bearing, when the outer ring 17 of the joint bearing needs to be placed in the middle of the clamping plate 8, pull the pull rod 16 to both sides. When the limit groove 10 on the pull rod 16 moves to the position of the L-shaped limit plate 12, the tension spring 13 pulls the L-shaped limit plate 12 downward and enters the interior of the limit groove 10 to limit the clamping plate 8. During the movement of the clamping plate 8, the pulley 19 at the bottom of the clamping plate 8 rotates with the movement of the clamping plate 8, reducing the friction between the bottom of the clamping plate 8 and the top of the workbench 1, so that the movement and replacement of the clamping plate 8 are smooth.
