[0032] This embodiment provides a disassembly and assembly device for disassembling a workpiece 100 with a through hole from a mounting hole of a mounting seat 200. The disassembly and assembly device can meet both disassembly requirements and installation requirements, and can improve the work efficiency of installing or disassembling the workpiece 100.

[0033] Please refer to Figures 1 to 4The disassembly and assembly device comprises a screw rod 1, a clamp 2, a support sleeve 3, and a rotating member 4. The screw rod 1 can be inserted into the through hole; the clamp 2 comprises a first clamping member 21 and a second clamping member 22, the first clamping member 21 is connected to the screw rod 1, and the second clamping member 22 is detachably connected to the screw rod 1, and the first clamping member 21 and the second clamping member 22 are used to clamp the workpiece 100 from both ends of the workpiece 100; the support sleeve 3 is rotatably sleeved on the screw rod 1, and the support sleeve 3 has a receiving cavity 31 and an opening 32 communicating with the receiving cavity 31, and the opening 32 faces the first clamping member 21, and the support sleeve 3 is used to abut against the mounting seat 200, and the opening 32 is communicated with the mounting hole, and the receiving cavity 31 is configured to at least accommodate the first clamping member 21 and the workpiece 100 at the same time; the rotating member 4 is screwed to the screw rod 1 and is used to press the support sleeve 3 against the mounting seat 200.

[0034] Specifically, in this embodiment, the disassembly and assembly device is divided into two modes: disassembly of the workpiece 100 and installation of the workpiece 100 . When disassembling the workpiece 100, first clamp the workpiece 100 in the mounting hole by the first clamping member 21 and the second clamping member 22, and the mounting seat 200 is fixed; then, the support sleeve 3 is pressed against the mounting seat 200 by the pre-tightening rotating member 4, and the support sleeve 3 is automatically aligned with the mounting hole. At this time, the axes of the support sleeve 3, the first clamping member 21, the second clamping member 22 and the workpiece 100 are all colinear; finally, the rotating member 4 is rotated while limiting the rotation of the screw 1, and the relative rotation of the screw 1 and the rotating member 4 makes the screw 1 move linearly along its axial direction, thereby moving the entire fixture 2 and the workpiece 100 linearly, and pulling the workpiece 100 out of the mounting hole of the mounting seat 200; after the first clamping member 21 and the workpiece 100 have entered the accommodating cavity 31 of the support sleeve 3, the workpiece 100 is removed from the fixture 2, and the process of disassembling the workpiece 100 is completed.

[0035] When installing the workpiece 100, firstly, the screw 1 is passed through the entire installation hole, and the installation seat 200 is located between the support sleeve 3 and the clamp 2; then the workpiece 100 outside the installation seat 200 is clamped by the clamp 2, and finally the rotation of the rotating member 4 is rotated while limiting the rotation of the screw 1, so that the entire clamp 2 and the workpiece 100 move linearly along the axial direction of the screw 1, and the workpiece 100 is pulled into the installation hole of the installation seat 200; when the end surface of the workpiece 100 and the second clamping member 22 are flush with the edge of the installation hole, the clamp 2 is removed, and the process of installing the workpiece 100 is completed. The disassembly and assembly device can realize both the disassembly and installation of the workpiece 100, and improve the work efficiency of the device in disassembling and assembling the workpiece 100. Furthermore, during the disassembly or installation process, the workpiece 100 is subjected to uniform force without large impact and stress concentration. Therefore, the workpiece 100 can be well protected after disassembly or installation, effectively reducing the damage rate of the workpiece 100 during the disassembly or installation process and improving the performance and service life of the workpiece 100.

[0036] Alternatively, as in 2 and Figure 3 As shown, the first clamping member 21 includes a stopper 211 and a guide 212, the guide 212 is used to be inserted into the through hole, and the stopper 211 and the second clamping member 22 are used to clamp the workpiece 100 from both ends of the workpiece 100. Specifically, in this embodiment, the first clamping member 21 is arranged in a T-shape, and the guide 212 can be inserted into the workpiece 100 along the through hole, so that the stopper 211 abuts against the workpiece 100, and then the workpiece 100 is clamped from both ends of the workpiece 100 by the stopper 211 and the second clamping member 22, so that the fixture 2 can better clamp the workpiece 100.

[0037] Optionally, both the stopper 211 and the second clamping member 22 are provided with a flexible pad, and the flexible pad is used to contact the workpiece 100. Specifically, in this embodiment, the flexible pad is used as a buffer component between the stopper 211 and the workpiece 100 and between the second clamping member 22 and the workpiece 100. By utilizing the material properties of the flexible pad itself, the wear of the stopper 211 and the workpiece 100 during the disassembly process can be reduced, and the wear of the second clamping member 22 and the workpiece 100 during the disassembly process can also be reduced. Such a configuration can, on the one hand, increase the service life of the disassembly device; on the other hand, it can also reduce the wear of the workpiece 100.

[0038] Alternatively, if Figure 2 and Figure 3 As shown, the guide portion 212 is cylindrical; or, the guide portion 212 is conical, and the large end of the cone is connected to the stopper 211. In this embodiment, the through hole of the workpiece 100 is generally a cylindrical hole, and it is more labor-saving to insert or pull out the cylindrical guide portion 212 into or out of the through hole. Alternatively, the guide portion 212 is set to be conical, and the conical guide portion 212 will not generate friction with the inner wall of the through hole of the workpiece 100, thereby reducing the resistance when the guide portion 212 is inserted into or pulled out of the through hole. Both shapes of the guide portion 212 facilitate the operation of the fixture 2 to clamp the workpiece 100 or remove it from the workpiece 100.

[0039] In this embodiment, at least one of the first clamping member 21 and the second clamping member 22 is movable on the screw rod 1 .

[0040] Specifically, the first clamping member 21 is movable on the screw rod 1. Figure 2As shown, the first clamping member 21 is screwed to the screw rod 1. At this time, the second clamping member 22 can be fixed or movable on the screw rod 1. In this embodiment, the workpiece 100 to be disassembled has a variety of lengths. The first clamping member 21 is threadedly connected to the screw rod 1, so that the first clamping member 21 can be moved along the axial direction of the screw rod 1, and the distance between the first clamping member 21 and the second clamping member 22 can be adjusted. When the length of the workpiece 100 is greater than the distance between the first clamping member 21 and the second clamping member 22, the second clamping member 22 is fixed on the screw rod 1, and the distance between the first clamping member 21 and the second clamping member 22 is increased to accommodate the workpiece 100 by only moving the first clamping member 21 on the screw rod 1; or the first clamping member 21 and the second clamping member 22 are moved on the screw rod 1 at the same time, so that the workpiece 100 is clamped from both ends by the first clamping member 21 and the second clamping member 22.

[0041] Specifically, the second clamping member 22 is movable on the screw rod 1. The second clamping member 22 is sleeved on the screw rod 1, and the disassembly and assembly device also includes a locking nut 5, which is threadedly connected to the screw rod 1, and the locking nut 5 is used to tighten the second clamping member 22 to the workpiece 100. At this time, the first clamping member 21 can be fixed or movable on the screw rod 1. The locking nut 5 is threadedly connected to the screw rod 1, and the second clamping member 22 is detachably connected to the screw rod 1, so that the second clamping member 22 and the locking nut 5 can also be moved along the axial direction of the screw rod 1, and the spacing between the first clamping member 21 and the second clamping member 22 can be adjusted. When the length of the workpiece 100 is greater than the distance between the first clamping member 21 and the second clamping member 22, the first clamping member 21 is fixed on the screw rod 1, and only the second clamping member 22 is moved on the screw rod 1; or the first clamping member 21 and the second clamping member 22 are moved on the screw rod 1 at the same time, so that the distance between the first clamping member 21 and the second clamping member 22 is increased to accommodate the workpiece 100, and then the workpiece 100 is clamped from both ends by the first clamping member 21 and the second clamping member 22.

[0042] In this way, when at least one of the first clamping member 21 and the second clamping member 22 can be moved on the screw 1, the distance between the first clamping member 21 and the second clamping member 22 can be adaptively adjusted as the length of the workpiece 100 changes, so that the clamp 2 can be suitable for workpieces 100 of different lengths, thereby improving the practicability of the disassembly and assembly device.

[0043] In other embodiments, Figure 2As shown, the locking nut 5 can also be a locking bolt, by threading the locking bolt on the first clamping member 21, and the second clamping member 22 is abutted against the workpiece 100 through the locking bolt. The locking bolt and the second clamping member 22 can also move along the axial direction of the screw rod 1, so that the second clamping member 22 can cooperate with the first clamping member 21 to adapt to the clamping of workpieces 100 of different lengths. In this case, the length of the screw rod 1 can be shortened, reducing the manufacturing cost.

[0044] Optionally, the roughness of the side of the support sleeve 3 abutting against the mounting seat 200 is greater than the roughness of the side of the support sleeve 3 abutting against the rotating member 4. In this example, during the disassembly and assembly operation, the support sleeve 3 has two force-bearing surfaces, one is the surface abutting against the mounting seat 200, and the other is the surface abutting against the rotating member 4. The roughness of the side of the support sleeve 3 abutting against the mounting seat 200 is set to be greater than the roughness of the side abutting against the rotating member 4. When the rotating member 4 is rotated, the support sleeve 3 and the rotating member 4 can be prevented from rotating together, and the workpiece 100 can be driven to move linearly by rotating the rotating member 4. In the absence of an auxiliary tool to clamp the support sleeve 3, the workpiece 100 can also be driven to move linearly by rotating the rotating member 4, thereby improving the practicality of the disassembly and assembly device.

[0045] Optionally, the disassembly and assembly device further includes a mounting member 7, and the screw rod 1 is selectively inserted into the mounting member 7 and the support sleeve 3, and the length of the mounting member 7 along the axial direction of the screw rod 1 is less than the length of the support sleeve 3, and when the screw rod 1 is inserted into the mounting member 7, one end of the mounting member 7 is used to abut against the mounting seat 200, and the other end is used to abut against the rotating member 4. In this embodiment, the support sleeve 3 of the disassembly and assembly device can also be replaced with the mounting member 7, and the installation of the workpiece 100 can be achieved through the mounting member 7; the support sleeve 3 is replaced with a mounting member 7 with a smaller length, and the length of the screw rod 1 can be shortened at this time, thereby shortening the overall length of the disassembly and assembly device. For example, when the workpiece 100 is installed in a narrow space, when the overall length of the disassembly and assembly device cannot meet the working condition requirements, the support sleeve 3 is replaced with the mounting member 7 to install the workpiece 100 in the narrow space. In addition, when the mounting member 7 is selected, the use length of the screw rod 1 is shortened, and the manufacturing cost is also reduced.

[0046] Optionally, the support sleeve 3, the first clamping member 21 and the second clamping member 22 are all made of high-strength alloy steel. In this embodiment, the mounting seat 200 and the rotating member 4 will generate a large friction force with the support sleeve 3; the first clamping member 21 and the second clamping member 22 will generate a large friction force with the workpiece 100. Using high-strength alloy steel to make the support sleeve 3, the first clamping member 21 and the second clamping member 22 can improve the wear resistance of the disassembly and assembly device, thereby increasing the service life of the disassembly and assembly device.

[0047] Furthermore, in other embodiments, the entire disassembly and assembly device is made of high-strength alloy steel, so that its wear resistance, yield strength, tensile strength, bending strength, etc. can meet the use requirements, thereby also improving the service life of the disassembly and assembly device.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
