[0025] Beneficial effects of the present invention:

[0026] 1. The two grinding wheels are driven by a dual-axis motor to rotate at high speed. At the same time, the pipe body remains stable under the support of the first support roller and the second support roller. By adjusting the sliding position of the second support roller on the workbench, it can adapt to pipe bodies of different diameters to achieve good clamping applicability. During the grinding process, the outer peripheral wall of the grinding wheel is in friction contact with the outer peripheral wall of the pipe body to remove burrs and oxide layers on its surface to achieve a polishing effect; at the same time, the dust suction fan starts to work and generates a strong suction force. The dust suction pipe serves as a channel connecting the dust suction fan and the hollow dust suction block. Its spring tubular design makes the dust suction pipe have a certain degree of elasticity and flexibility, which is better The hollow dust suction block is connected to the polishing hood to adapt to the relative movement between the polishing hood and the pipeline body, and the iron filings and fine dust generated during the polishing process are sucked into the dust suction pipe; these iron filings and dust are then transported to the processing box, and the rotating magnetic roller connected inside the processing box can absorb the iron filings and separate them from the dust. After being processed by the magnetic roller, the remaining dust moves to the lower end of the processing box for further processing, ensuring the cleanliness of the production environment and the health and safety of the workers, improving the applicability and flexibility of the polishing device, realizing the real-time collection and processing of iron filings and dust during the polishing process, and reducing the harm of iron filings and dust to the production environment and the health of workers.

[0027] 2. Install and sleeve the external dust collecting bag on the discharge pipe, and use the dust suction fan to suck the debris and smoke generated during the polishing process and transport them to the inside of the processing box. After entering the dust suction channel, the output shaft of the first motor drives the magnetic roller to rotate. At this time, the magnetic roller adsorbs the iron filings in the smoke transported in the dust suction channel, and reduces the occurrence of smoke escape through the blocking of the dustproof seal. The iron filings adsorbed by the outer wall of the rotating magnetic roller are scraped off through the blocking of the triangular guide block, slide along the triangular guide block and are discharged to the outside from the discharge hole, which facilitates the continuous adsorption of the magnetic roller. The smoke inside the dust suction channel after the iron filings are adsorbed enters the discharge hopper and is discharged from the discharge pipe to the inside of the dust collecting bag for collection, which further captures and collects dust, reduces its pollution to the environment, improves the dust prevention effect, ensures the continuous dust suction ability of the dust suction system, and avoids the decrease in dust suction efficiency due to the accumulation of iron filings.

[0028] 3. The piston rod of the first cylinder pushes the lifting block and the counterweight block to slide along the column, and the lifting block is adjusted to a suitable height for use. The piston rod of the second cylinder pushes the connecting block to slide along the lifting block through the limit groove, which facilitates the adjustment of the connecting block to a suitable height and position for use, and further adjusts the polishing cover to a suitable position, which is suitable for the polishing of pipe bodies of different sizes, improves the adaptability and flexibility of the polishing equipment, and reduces the phenomenon of missed polishing and over-polishing during the polishing process.

[0029] 4. The output shaft of the forward and reverse motor drives the lead screw to rotate along the support, so that the lead screw pushes the U-shaped block to move along the axial direction of the lead screw, thereby driving the second support roller to slide on the workbench, and adjusting the distance between the second support roller and the first support roller to adapt to the polishing and grinding of pipe bodies of different sizes, thereby reducing errors in the polishing process and improving polishing accuracy and surface quality.

[0030] 5. The output shaft of the second motor drives one of the pulleys to rotate, which is transmitted to the other pulley through belt friction, so that the first support roller drives the pipe body to rotate. At this time, the friction force of the pipe body drives the second support roller to rotate synchronously. The rotating pipe body facilitates polishing and ensures stable rotation of the pipe body during polishing, reduces the problem of local over-polishing or insufficient polishing, and facilitates the polishing of pipe bodies of different specifications.

[0031] 6. The slider of the pneumatic slide table drives the push block to move synchronously, so that the push block pushes the push rod to slide along the positioning block, and the positioning block pushes the C-shaped block and the rotating shaft to move synchronously. The rotating shaft drives the round block to frictionally contact the outer surface of one end of the pipe body, and pushes the pipe body to slide along the first supporting roller. The rotating pipe body during the polishing process drives the round block in contact with it to rotate along the rotating shaft, which facilitates the movement of the pipe body during the polishing process, and at the same time facilitates the unloading operation of the pipe body after polishing, and facilitates the pushing and polishing of pipe bodies of different lengths, ensuring that the pipe body is polished evenly and stably during the polishing process, thereby improving the polishing quality.

[0049] The hollow dust suction block 507 is connected to a dust suction pipe 508, the middle part of which is in the shape of a spring tube, the other end of the dust suction pipe 508 is connected to a dust suction fan 509, the lower end of the dust suction fan 509 is connected to a processing box 510, and a magnetic roller 511 is rotatably connected inside the processing box 510.

The top surface of the dust seal 512 is fixedly connected to the inner wall of the upper end of the processing box 510, and a triangular material guide block 513 is slidably connected to the outer peripheral wall of the magnetic roller 511. A discharge hole 514 is opened on the outer wall of the processing box 510; the magnetic roller 511 absorbs iron filings in the smoke transported inside the dust suction channel 518, and reduces the occurrence of smoke escape through the blocking of the dust seal 512.

[0051] A first motor 515 is installed on the outer wall of the processing box 510 through a mounting seat, and the output shaft of the first motor 515 is coaxially connected to the central axis of the magnetic roller 511. A discharge hopper 516 is fixedly provided at the lower end of the processing box 510, and the discharge hopper 516 is connected to the dust suction channel 518, and the lower end of the discharge hopper 516 is connected to a discharge pipe 517; the smoke inside the dust suction channel 518 after the iron filings are adsorbed enters the discharge hopper 516 and is discharged from the discharge pipe 517 to the inside of the dust collecting bag for collection, so as to further capture and collect the dust.
