Technical Field

[0001] This utility model relates to the field of vacuum pump maintenance technology, specifically to auxiliary tools for disassembling and assembling vacuum pumps. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. In many industrial and electronic devices, a vacuum system is often required to achieve the required vacuum level. When a vacuum pump jams, the vanes collide, the pump chamber is scratched by foreign objects, or the temperature rises abnormally, it needs to be completely disassembled, cleaned, and repaired. Vacuum pump disassembly and assembly auxiliary tools are mainly used to simplify the disassembly and assembly process of vacuum pumps, improve work efficiency, and reduce operational risks. In order to improve the disassembly and maintenance efficiency of vacuum pumps, a disassembly and assembly auxiliary tool is needed. However, existing disassembly and assembly auxiliary tools still have the following shortcomings.

[0003] When using existing disassembly and assembly auxiliary tools, most of them cannot adjust the angle of the vacuum pump as needed. This forces maintenance personnel to twist their bodies or arms or use unnatural postures to adapt to the fixed angle of the tool, increasing the difficulty of operation and reducing efficiency. At the same time, tools with incorrect angles cannot fully fit the hexagonal head of the bolt or nut, making subsequent disassembly extremely difficult. This results in a decrease in the practicality and efficiency of disassembly and assembly auxiliary tools. Utility Model Content

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3As shown, the vacuum pump disassembly and assembly auxiliary tool includes a workbench 1 and a rotating assembly 4. The workbench 1 has a mounting slot 2 on its rear side, and a movable seat 3 is connected inside the mounting slot 2. The rotating assembly 4 is located on the outer side of the movable seat 3. The rotating assembly 4 includes a mounting vertical plate 401, a limiting cylinder 402, a limiting rod 403, a limiting slider 404, a return spring 405, a limiting groove 406, a limiting through hole 407, a receiving groove 408, and a receiving slider 409. A limiting cylinder 402 is installed on the outer side of the mounting vertical plate 401, and a limiting rod 403 is connected inside the limiting cylinder 402. A limiting slider 404 is also added to the outside of the limiting rod 403. The positioning rod 403 has a return spring 405 inside the external limiting cylinder 402. A limiting groove 406 is formed inside the limiting cylinder 402. A limiting through hole 407 is formed on the outer side of the movable seat 3, and a receiving groove 408 is formed inside the limiting through hole 407. A receiving slider 409 is connected inside the receiving groove 408. The limiting cylinder 402 is vertically distributed on the mounting vertical plate 401 and is fixedly connected to the mounting vertical plate 401 by bolts. The limiting rod 403 is embedded in the limiting cylinder 402 and is elastically connected to the limiting cylinder 402 by the return spring 405. The internal dimensions of the receiving groove 408 are similar to those of the receiving slider 409. The external dimensions of the 09 are compatible, and the receiving slider 409 is slidably connected to the movable seat 3 through the receiving groove 408. The limiting cylinder 402 is fixedly installed on the lower end of the mounting vertical plate 401 by fastening bolts. The limiting rod 403 is installed inside the limiting cylinder 402. The return spring 405 makes the limiting rod 403 and the limiting cylinder 402 elastically connected. The external dimensions of the limiting slider 404 added to the outside of the limiting rod 403 are compatible with the internal dimensions of the limiting groove 406 opened inside the limiting cylinder 402. Thus, the limiting slider 404 and the limiting groove 406 limit and fix the limiting rod 403 inside the limiting cylinder 402, preventing the limiting rod 403 from going out. The movable seat 3 features elastic displacement, and the external dimensions of the limiting rod 403 are matched with the internal dimensions of the limiting through hole 407 on the outer side of the movable seat 3. This allows the use angle of the movable seat 3 to be adjusted by the limiting rod 403 in conjunction with the limiting through hole 407, so that the angle of the movable seat 3 is fixed after rotation, thus improving the efficiency of vacuum pump assembly and disassembly. The internal dimensions of the receiving groove 408 inside the movable seat 3 are matched with the external dimensions of the receiving slider 409 added to the upper inner side of the mounting vertical plate 401. This allows the receiving groove 408 in conjunction with the receiving slider 409 to increase the stability of the movable seat 3 during rotation adjustment, thereby improving the practicality and efficiency of the vacuum pump assembly and disassembly auxiliary tool.

[0022] like Figures 1 to 3As shown, the upper end of the movable seat 3 is provided with an adjustment component 5. The adjustment component 5 includes a receiving seat 501, a mounting groove 502, a mounting slider 503, and a mounting base plate 504. The receiving seat 501 has mounting grooves 502 on both sides inside, and the mounting slider 503 is connected inside the mounting grooves 502. The mounting base plate 504 is installed on the upper end of the mounting slider 503. The adjustment component 5 also includes a mounting bracket 505, a limiting groove 506, and a sliding lock 507. The mounting base plate 504 is provided with a mounting bracket 505 on the upper end. The mounting base plate 504 has limiting grooves 506 on both sides inside, and the sliding lock 507 is connected inside the limiting grooves 506. The internal dimensions of the mounting groove 502 are adapted to the external dimensions of the mounting slider 503, and the mounting slider 503 is slidably connected to the receiving seat 501 through the mounting groove 502. There are two mounting sliders 503, and the two mounting sliders 503 are symmetrically arranged about the central axis of the front of the mounting base plate 504. The mounting base 501 is fixedly installed on the upper end of the movable base 3 by fastening bolts on both sides of the lower end of the mounting base 504. The internal dimensions of the mounting groove 502 inside the mounting base 501 are adapted to the external dimensions of the mounting slider 503 added to the lower end of the mounting base 504. Thus, the mounting base 504 can move stably on the upper end of the mounting base 501 through the mounting groove 502 and the mounting slider 503. The limiting grooves 506 on both sides inside the mounting base 504 are equipped with sliding locking devices 507 to fix the mounting bracket 505 on the upper end of the mounting base 504. The position of the mounting bracket 505 is adjusted according to the specifications and dimensions of the vacuum pump to be disassembled and assembled. The sliding locking device 507 and the limiting groove 506 are used to lock and fix the position of the mounting base 504. Thus, the disassembly and assembly auxiliary tool can quickly adjust the position of the mounting bracket 505 according to the bottom mounting dimensions of the vacuum pump, improving the flexibility and dynamism of the disassembly and assembly auxiliary tool during use.

[0023] In summary, when using this vacuum pump assembly and disassembly auxiliary tool, first place the vacuum pump on the mounting bracket 505. The mounting bracket 505 rests on the receiving seat 501 via the mounting base plate 504. According to the pump body size, push the mounting bracket 505 to move the mounting slider 503 along the mounting groove 502. After it is in place, use the sliding lock 507 to lock it at the limiting groove 506. Next, when the angle needs to be adjusted, pull the limiting rod 403 to compress the return spring 405, so that the rod end is disengaged from the current limiting through hole 407. After rotating the movable seat 3 to the target angle, the limiting rod 403 automatically springs into the new limiting through hole 407 under the action of the spring to complete the fixation. During this process, the limiting slider 404 slides in the limiting groove 406 to prevent the rod from shifting. At the same time, the receiving slider 409 moves along the receiving groove 408 to provide additional stability. Finally, during the entire operation, commonly used tools can be placed in the storage slot 508 of the workbench 1 for easy access.
