DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Figure 1 The schematic diagram of the structure of the traction rubber ball joint disassembly and assembly device in the utility model is shown. Figure 2 A cross-sectional view of the traction rubber ball joint disassembly and assembly device of the utility model is shown. Figure 3 A top view of the support in the utility model is shown; Figure 4 A top view of the floating support block in the utility model is shown; Figure 5 Another cross-sectional view of the traction rubber ball hinge disassembly and assembly device in the utility model is shown, the traction rubber ball hinge disassembly and assembly device comprises: a base 1, one or more supports 2, one or more pressing sleeves 3 and a traction rod 4, one or more supports 2 are installed on the base 1, the traction rod 4 is placed on the support 2, both ends of the traction rod 4 are provided with fixing holes, a rubber joint ball hinge core 41 is installed in the fixing holes, any of the pressing sleeves 3 is located above the rubber joint ball hinge core 41, and a buffer mechanism 5 is provided below the rubber joint ball hinge core 41; the traction rod 4 is driven by one or more pressing sleeves 3 to move in the support 2. In this embodiment, the traction rubber ball hinge disassembly and assembly device comprises: two supports 2 and four pressing sleeves 3, and the two supports 2 are symmetrically distributed on both sides of the base 1.

[0028] Furthermore, the middle area of ​​the rubber joint ball hinge core 41 is elliptical, the two ends of the rubber joint ball hinge core 41 are rectangular, and a through hole is provided in the rectangular. The elliptical middle area of ​​the rubber joint ball hinge core 41 increases its contact area, which is beneficial for the rubber joint ball hinge core 41 to transfer the force it receives to other components. The rubber joint ball hinge core 41 transfers the force it receives to other components in a timely manner, thereby reducing the risk of deformation, improving the installation quality, and reducing the number of repeated corrections by personnel. Secondly, a through hole is provided in the rectangular, and the through hole is connected to a transport tool, which is convenient for the transport tool to transport the entire traction rod 4 to the corresponding position.

[0029] Furthermore, a preset gap is provided between the inner wall of the support 2 and the rubber joint ball hinge core 41, that is, the inner wall of the support 2 has no contact with the rubber joint ball hinge core 41. The preset gap is used to reduce the friction between the support 2 and the rubber joint ball hinge core 41, and avoid the friction between the support 2 and the rubber joint ball hinge core 41 causing the rubber joint ball hinge core 41 to wear, which is beneficial to prolonging the service life of the rubber joint ball hinge core 41.

[0030] Furthermore, a first limiting boss 21 is provided on the inner wall of the support 2, and one or more limiting grooves 22 are provided on the first limiting boss 21. In this embodiment, two limiting grooves 22 are provided on the first limiting boss 21, and the first limiting boss 21 is used to limit the moving range of the traction rod 4, so as to prevent the traction rod 4 from moving downward too far and exceeding the load limit, thereby reducing the risk of damage to the rubber joint hinge core due to excessive force; the two limiting grooves 22 are used to limit the moving range and rotation angle of the floating support block 51. During the installation process, the hydraulic press will generate vibrations during operation, and this vibration will drive the press sleeve 3 and the traction rod 4 to move slightly, resulting in poor installation quality. After installation, manual repeated measurements are required to correct errors. The two limiting grooves 22 limit the rotation angle of the floating support block 51, which is conducive to reducing manual repeated measurement correction errors, reducing the number of repeated measurements, and improving work efficiency.

[0031] Furthermore, the buffer mechanism 5 includes: a floating support block 51, a positioning pin 53 and a compression spring 52. The floating support block 51 is located above the positioning pin 53. A compression spring 522 is provided on the surface of the positioning pin 53. One end of the compression spring 52 is connected to the floating support block 51, and the other end of the compression spring 52 is connected to the base 1. The floating support block 51 is used to support the rubber joint ball hinge core 41, the compression spring 52 is used to buffer the downward pressure on the rubber joint ball hinge core 41, and the positioning pin 53 is used to limit the range of movement of the floating support block 51 to prevent the friction between the movable support block 51 and the support 2 from causing wear.

[0032] Furthermore, one or more second limiting bosses 511 are provided on the side of the floating support block 51, and the second limiting bosses 511 are located in the limiting groove 22. The second limiting bosses 511 are used to be inserted in the second limiting groove 22, thereby limiting the rotation angle of the floating support block 51, and preventing the floating support block 51 from slightly displacing during use, resulting in poor installation quality, and requiring manual repeated measurements to correct errors after installation. The two limiting grooves 22 limiting the rotation angle of the floating support block 51 are conducive to reducing manual repeated measurement correction errors, reducing the number of repeated measurements, and improving work efficiency.

[0033] Furthermore, a mounting groove 512 is provided on the upper end surface of the floating support block 51, and the floating support block 51 is connected to the rubber joint ball hinge core 41 based on the mounting groove 512. The mounting groove 512 is used to fix the rubber joint ball hinge core 41, and the rubber joint ball hinge core 41 is inserted into the corresponding mounting groove 512. The side wall of the mounting groove 512 has a limiting effect on the rubber joint ball hinge core 41, reducing the displacement amplitude of the rubber joint ball hinge core 41 during use, improving the installation quality, reducing the manual repeated measurement correction error, reducing the number of repeated measurements, and improving work efficiency.

[0034] Furthermore, the installation groove 512 is deflected by a preset angle α based on its geometric center. In this embodiment, the installation groove 512 is deflected by a preset angle α of 4.6° based on its geometric center. The design of the installation convex groove angle ensures that the angle of the traction rod is adjusted before installation, which is conducive to achieving self-positioning of dimensions such as the installation height, center distance, deflection angle and parallelism of the rubber joint. The rubber joint ball hinge core 41 is inserted into the corresponding installation groove 512, wherein the installation groove 512 has an action force on the rubber joint ball hinge core 41 to make it close to the side wall of the installation groove 512. When the rubber joint ball hinge cores 41 on both ends of the traction rod 4 are installed in the corresponding installation grooves 512, the rubber joint ball hinge cores 41 at both ends are subjected to the action force of the corresponding installation grooves 512 to make them close to the side wall of the installation groove 512, ensuring that the traction rod 4 remains stable and avoiding the traction rod 4 from being offset during use, which is conducive to improving the installation accuracy, thereby improving the quality of installation, reducing the number of manual measurement error correction, and improving work efficiency.

[0035] Furthermore, a positioning pin 53 is provided below the floating support block 51, and a compression spring 52 is provided on the surface of the positioning pin 53, one end of the compression spring 52 is connected to the floating support block 51, and the other end of the compression spring 52 is connected to the base 1. The compression spring 52 is used to buffer the pressure of the floating support block 51 moving downward. When the floating support block 51 is driven by the traction pull rod to move downward, the floating support block 51 will exert a downward pressure on the compression spring 52 during the downward movement. The compression spring 52 is deformed after being subjected to the pressure of the floating support block 51, and the kinetic energy of the floating support block 51 is converted into the elastic potential energy of the compression spring 52, thereby realizing the buffering function.

[0036] Furthermore, the press sleeve 3 includes: an installation press sleeve and a removal press sleeve, and a clamping portion is provided on the top of the removal press sleeve. The installation press sleeve is used to install the rubber joint ball hinge core 41 to a specified position, and the removal press sleeve is used to remove the rubber joint ball hinge core 41 from a specified position. The installation press sleeve and the removal press sleeve are the same set of kits and have the same processing accuracy, so as to avoid using kits produced in different batches during installation and removal, resulting in low installation quality and requiring manual repeated measurements to correct errors, which is conducive to reducing the number of repeated measurements and improving work efficiency.

[0037] Furthermore, the base 1 is provided with a plurality of hooks, and the plurality of hooks are distributed at the top corners of the base 1 according to preset positions. In this embodiment, the base 1 is provided with four hooks, and one of the four hooks is correspondingly provided at one of the four top corners of the base 1, that is, the four hooks correspond to the four top corners respectively. The hooks are used to connect with a transportation vehicle, and the hooks are located at the four top corners of the base 1, so as to ensure that the force of the traction rubber ball joint disassembly and assembly device is evenly applied, and the traction rubber ball joint disassembly and assembly device can be smoothly moved to a designated position.

[0038] To sum up, the utility model provides a buffer mechanism to buffer the pressure on the ball hinge core of the rubber joint, thereby reducing the risk of different degrees of deformation of the rubber joint and improving the installation quality; secondly, the same set of kits are pressed and the processing accuracy is consistent, which avoids the use of kits produced in different batches during installation and disassembly, resulting in poor installation quality and the need for repeated manual measurements to correct errors, which is conducive to reducing the number of repeated measurements and improving work efficiency.
