The output end of the hydraulic cylinder 2 is fixedly connected with the hydraulic cylinder 2, and a mounting hole 404 is opened at the upper end of one side of the hydraulic cylinder 2. The threaded block 401 and the threaded groove 402 cooperate with each other to realize the disassembly and assembly between the output end of the hydraulic cylinder 2 and the cylinder body 5. At the same time, the elastic force of the mounting spring 408 can be used to make the mounting block 409 stuck into the mounting hole 404 or separated from it, so that when engaged, the threaded block 401 and the threaded groove 402 can be prevented from loosening the threads and affecting the firmness and stability of the cylinder body 5 installation.

[0041] In this embodiment, a threaded fitting structure is formed between the thread block 401 and the inside of the thread groove 402. The lower end of the thread block 401 is truncated cone-shaped. The threaded fitting between the thread block 401 and the inside of the thread groove 402 is used to realize the rapid disassembly and assembly between the output end of the hydraulic cylinder 2 and the cylinder body 5.

After that, the hydraulic cylinder 2 can work to make the cylinder body 5 extend and slide, and cooperate with the displacement sensor 6, the speed sensor 7 and the image sensor 9 to realize the comprehensive detection of displacement, speed, image, etc., so that the hydraulic drive device is more accurate;

[0045] At the same time, during the operation of the hydraulic cylinder 2, the hydraulic oil entering the filter box 1 is filtered through the filter plate 304 to prevent the hydraulic oil in the hydraulic system from entering the hydraulic cylinder 2, affecting the normal operation of the hydraulic cylinder 2 or causing damage, thereby preventing the cylinder body 5 from affecting its telescopic accuracy and causing a decline in the honing process. At the same time, when not in use, the positioning rod 307 can be moved to drive the sliding rod 302 to slide, so that the sliding block 309 slides in the fixing groove 310 to compress the fixing spring 308 until the positioning rod 307 is completely separated from the positioning hole 305, and then the filter can be closed through the sealing cover 306. The core plate 304 is taken out from the inside of the filter box 1, which is convenient for cleaning, maintaining or replacing the filter core plate 304. When installing, first move the positioning rod 307, then insert the filter core plate 304 into the filter box 1, and make the sealing cover 306 clamped into the reserved groove 303. At this time, the sealing ring 301 is used to improve the sealing performance of the lower end of the sealing cover 306 and the reserved groove 303. At the same time, the positioning rod 307 is loosened, and the elastic force of the fixing spring 308 is used to make the sliding rod 302 slide and drive the positioning rod 307 to clamp into the positioning hole 305, so as to ensure the firm clamping installation of the sealing cover 306.

[0046] When the cylinder body 5 needs to be disassembled for maintenance, the pull rod 403 can be pulled to drive the mounting block 409 to slide and compress the mounting spring 408 until it is completely disengaged from the inside of the mounting hole 404, and then the cylinder body 5 is rotated to realize the disassembly action. When installing the cylinder body 5, the pull rod 403 is first moved to make the mounting block 409 slide until it is completely entered into the inside of the mounting groove 407, and then the threads inside the threaded block 401 and the threaded groove 402 are matched to achieve the firm installation and fixation of the output end of the hydraulic cylinder 2 and the cylinder body 5. At the same time, the pull rod 403 is loosened, and the elastic force of the mounting spring 408 is used to make the mounting block 409 stuck to the inside of the mounting hole 404, so as to avoid the thread block 401 and the threaded groove 402 from loosening and affecting the firmness and stability of the cylinder body 5 installation.
