Two first guide posts 207 are fixedly connected to the inner wall of the right mounting groove 202.

[0028] In one embodiment, such as Figure 2 As shown, the left fixing block 300 includes a fixing block body 301, a left mounting groove 302, a second sliding mounting hole 303, a left positioning pin 304, a second guide post 305, a guide rod 306, and a lead screw 307. The fixing block body 301 has a left mounting groove 302, reserving space for the left side of the piston 700. The top of the fixing block body 301 has a second sliding mounting hole 303.

Rotating the screw 307 allows the right slider 200 to slide left and right due to the threaded cooperation between the threaded hole 204 and the screw 307.

[0029] In one embodiment, such as Figure 3 As shown, the clamping assembly 400 includes an upper fixing plate 401, a connecting rod 402, a pressure plate 403, a sliding rod 404, and a spring 405. The connecting rod 402 is fixedly connected to the bottom of the upper fixing plate 401. The pressure plate 403 is fixedly connected to the side of the connecting rod 402 away from the upper fixing plate 401. Two sliding rods 404 are symmetrically arranged on the back of the pressure plate 403. The spring 405 is sleeved on the sliding rod 404.

[0030] In this embodiment, the upper fixing plate 401 is pulled upward, causing the pressure plate 403 to press the springs 405 on the two slide rods 404. After the upper fixing plate 401 is released, under the action of the elastic force of the spring 405, the spring 405 pushes the pressure plate 403 downward, thereby pressing the upper surface of the piston 700.

[0031] In one embodiment, such as Figure 1 and Figure 3As shown, the connecting rod 402 cooperates with the first sliding mounting hole 206 and the second sliding mounting hole 303 respectively, so that the clamping assembly 400 can slide freely on the top of the right slider 200 and the left fixed block 300 respectively; the sliding rod 404 cooperates with the first guide post 207 and the second guide post 305 respectively, so that the sliding rod 404 can slide up and down in the first guide post 207 and the second guide post 305 respectively, thereby guiding the sliding of the clamping assembly 400.

[0032] In one embodiment, such as Figure 4 As shown, the telescopic cylinder 500 includes a left telescopic cylinder 501, a right telescopic cylinder 502, a threaded connection part 503, and a nut 504.

The right U-shaped clamping plate 601 and the left U-shaped clamping plate 602 are located at the upper end of the telescopic cylinder 500. The bottom of both the right U-shaped clamping plate 601 and the left U-shaped clamping plate 602 is provided with a threaded mounting hole 603 that mates with the threaded connection part 503, allowing the auxiliary disassembly assembly to be inserted through the threaded mounting hole 603. The component 600 is threaded into the threaded connection part 503 and fastened by the nut 504, thereby enabling the auxiliary disassembly component 600 to move synchronously with the telescopic cylinder 500; the right U-shaped clamping plate 601 and the left U-shaped clamping plate 602 are symmetrically provided with two side fixing plates 604 on their sides. The side fixing plate 604 away from the right U-shaped clamping plate 601 has a fixing threaded hole 605, and a bolt 606 is threaded into the fixing threaded hole 605. A matching nut 607 is fitted on the bolt 606.

[0034] In one embodiment, such as Figure 4 As shown, the distance between the side fixing plates 604 on both sides of the right U-shaped clamping plate 601 is greater than the distance between the side fixing plates 604 on both sides of the left U-shaped clamping plate 602. This allows the side fixing plate 604 on one side of the right U-shaped clamping plate 601 to be fitted onto the outside of the side fixing plate 604 on one side of the left U-shaped clamping plate 602, thereby applying an upward pulling force to both sides of the piston 700 simultaneously.

[0035] In one embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, the piston 700 includes a piston head 701, a locating pin hole 702, a piston rod 703, and a piston mounting hole 704. The bottom of the piston head 701 has multiple locating pin holes 702, which are respectively matched with the right locating pin 205 and the left locating pin 304, so that the left and right sides of the bottom of the piston 700 can be fixed by the right locating pin 205 and the left locating pin 304 respectively. A piston rod 703 is slidably connected to the piston head 701. The end of the piston rod 703 away from the piston head 701 has a piston mounting hole 704 that matches the fixing threaded hole 605. A bolt 606 is passed through both the piston mounting hole 704 and the fixing threaded hole 605, and then a matching nut 607 is used to tighten it, thereby connecting the auxiliary disassembly assembly 600 and the piston 700.

[0036] Working principle: When disassembling the piston rod sealing fixture of the central mechanism, firstly, rotate the lead screw 307 to bring the right slider 200 close to the left fixed block 300 until the distance between the right slider 200 and the left fixed block 300 matches the size of the piston 700. Next, lift the upper fixing plate 401 in the right slider 200 and the left fixed block 300 respectively, and insert the piston 700 into the right positioning pin 205 and the left positioning pin 304 through the positioning pin hole 702 respectively. Release the upper fixing plate 401, and under the action of the spring 405, the pressure plate 403 presses firmly on the upper part of the piston head 701, so that it will not move arbitrarily during disassembly; at the same time, open the left telescopic cylinder 501. The right telescopic cylinder 502 and the telescopic cylinder 500 drive the auxiliary disassembly assembly 600 to retract until the fixing threaded holes 605 in the right U-shaped clamping plate 601 and the left U-shaped clamping plate 602 coincide with the piston mounting hole 704. The bolt 606 is simultaneously passed through the fixing threaded hole 605 and the piston mounting hole 704 and tightened with the matching nut 607 to connect the auxiliary disassembly assembly 600 and the piston 700. Then, the left telescopic cylinder 501 and the right telescopic cylinder 502 are activated at the same time to allow the auxiliary disassembly assembly 600 to pull the piston rod 703 upward until the piston rod 703 separates from the piston head 701, completing the disassembly of the piston 700.
