Its function is to convert hydraulic energy into mechanical energy. The hydraulic cylinder basically consists of a cylinder barrel, a cylinder head, a piston, a piston rod, a sealing device, a buffering device and an exhaust device. Inevitably, the surface of the oil cylinder is uneven during the processing, so a polishing device is usually needed to polish it.

Therefore, we provide a polishing device for processing a shield machine propulsion oil cylinder to solve the above problems. Content of the Utility Model

[0022] Refer to Figure 1 and Figure 2 As shown in FIGS. and, a polishing mechanism 3 is arranged on the back of the clamping mechanism 2, and a cleaning mechanism 4 is arranged outside the clamping mechanism 2. The clamping mechanism 2 includes a processing table 201. The bottom surface of the processing table 201 is fixedly connected with the upper surface of the fixed bottom plate 1. Above the processing table 201, there is a cylinder body 202. One end of several push rods 206 close to each other is fixedly connected with a clamping plate 205.

By pushing the clamping plate 205 to slide inside the sliding groove 204 through the push rod 206, it is convenient to clamp the cylinder body 202, and by using the sewage discharge groove 409 communicated with the sliding groove 204, the debris and dust liquid generated by polishing can be discharged into the collection groove 407 for collection.

[0023] Refer to Figure 3 As shown in FIG., one side surface of several clamping plates 205 away from each other is fixedly connected with a reinforcing ring 207. The inner wall of each reinforcing ring 207 is fixedly connected with the outer surface of the push rod 206. By using the reinforcing ring 207, it is fixed at the connection between the clamping plate 205 and the push rod 206, thereby improving the stability of the push rod 206 to push the clamping plate 205.

The mutually approaching ends of the two groups of reinforcing rods 208 are fixedly connected to the outer surface of the push rod 206. By using the two reinforcing rods 208, the stability of the push rod 206 pushing the clamping plate 205 can be further improved, so that the oil cylinder body 202 can be stably clamped.

The polishing rotating frame 303 is rotatably connected inside the support frame 301. The support frame 301 fixed on the fixed bottom plate 1 is used to support the polishing rotating frame 303, so that it is convenient to polish the upper surface of the oil cylinder body 202 by using the polishing structure.

The output end of the gearbox 403 is fixedly connected to a rotating rod 408. A fixed sleeve 404 is fixedly connected to the outer surface of the rotating rod 408. Equally spaced cleaning rods 405 are fixedly connected to the outer surface of the fixed sleeve 404. A cleaning brush 406 is fixedly connected to the end of each cleaning rod 405 away from the fixed sleeve 404. The cleaning ends of one group of cleaning brushes 406 are in contact with the upper surface of the oil cylinder body 202. A stepping motor 302 is fixedly connected to the inner wall of the support frame 301. The stepping motor 302 is an open-loop control motor that converts an electric pulse signal into an angular displacement or a linear displacement. The model of the stepping motor 302 is PH533HG1-NA. The output end of the stepping motor 302 is fixedly connected to the bottom surface of the polishing rotating frame 303. The stepping motor 302 is used to drive the polishing rotating frame 303 to rotate inside the support frame 301. Since the polishing rotating frame 303 can be telescoped, it is convenient to polish the upper surface of the oil cylinder body 202 by using the polishing wheel 306 rotating inside the polishing rotating frame 303.

[0027] Reference Figure 1 and Figure 2, a conveying pipe 401 is fixedly connected to the upper surface of the polishing rotating frame 303. One end of the conveying pipe 401 close to the oil cylinder body 202 penetrates through the polishing rotating frame 303 and extends above the polishing wheel 306. One end of the conveying pipe 401 close to the oil cylinder body 202 is fixedly communicated with a water spray nozzle 402. The right end of the rotating shaft 305 is fixedly connected to a rotating motor 304. The outer surface of the rotating motor 304 is fixedly connected to the right side surface of the polishing rotating frame 303. By driving the rotation of the rotating shaft 305 through the rotating motor 304, it is convenient to provide power for the polishing structure and the cleaning structure, so as to complete the polishing of the upper surface of the oil cylinder body 202 and the cleaning of the sundries on the upper surface of the oil cylinder body 202.

[0028] Working principle: When in use, first connect the clamping hydraulic rod 203, the stepping motor 302 and the rotating motor 304 to the power supply. When it is necessary to polish the shield machine propulsion oil cylinder by using this polishing device, first place the device on the horizontal ground manually, so that the device can be used to stably process the shield machine propulsion oil cylinder. Then, lift the oil cylinder body 202 onto the processing table 201 by using a lifting tool, and drive the push rod 206 to push the clamping plate 205 to slide in the sliding groove 204 opened on the processing table 201 by controlling the power supply of the clamping hydraulic rod 203 until the oil cylinder body 202 on the processing table 201 is clamped and limited.

[0029] Then, manually connect the external cooling water pipe to the conveying pipe 401, which is convenient to use the cooling water in the conveying pipe 401 to be sprayed out from the water spray nozzle 402 to cool down the polishing wheel 306. By controlling the power supply of the stepping motor 302 and the rotating motor 304, the stepping motor 302 can be used to drive the polishing rotating frame 303 to rotate in the support frame 301. The polishing rotating frame 303 can move up and down telescopically, and the rotating motor 304 is used to drive the rotating shaft 305 to drive the polishing wheel 306 to rotate, so as to conveniently polish the upper surface of the clamped oil cylinder body 202 by using the high-speed rotating polishing wheel 306. At the same time, the water sprayed out by the water spray nozzle 402 can be used to clean the dust adsorbed on the outer surface of the polishing wheel 306, and the cooling water can also be used to adsorb the dust generated by polishing.

[0030] While the rotating shaft 305 drives the polishing wheel 306 to rotate, the rotating shaft 305 can rotate within the gearbox 403, so that the structure within the gearbox 403 enables the rotating rod 408 to output relatively low rotational power. Furthermore, the rotating rotating rod 408 can drive the fixed sleeve 404, the cleaning rod 405, and the cleaning brush 406 to rotate, thereby using the rotating cleaning brush 406 to clean the debris generated by polishing the upper surface of the cylinder body 202. The liquid mixture of cooling water, debris, and dust is transported through the sliding groove 204 and the sewage discharge groove 409 to the collection tank 407 for collection. Thus, it is convenient to use this polishing device to polish the propulsion cylinder of the shield machine.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
