The base trolley 1 can adopt a wheeled, tracked or other suitable structure for movement, and can be driven forward, backward, left, right, etc. by motor or hydraulic drive or directly manually pushed. The stand 2 is vertically installed on the base trolley 1 and serves to support and fix the vertical sliding platform structure 3. The stand 2 has sufficient rigidity and stability to ensure that it does not sway or tilt during polishing. The vertical sliding platform structure 3 is movably connected to the stand 2 to move up and down. This lifting function enables the polishing and polishing structure 5 to accurately position and adjust the workpiece in the vertical direction; one end of the telescopic horizontal structure 4 is fixedly connected to the vertical sliding platform structure 3, and the other end is connected to the polishing and polishing structure 5. Through the internal transmission mechanism, the telescopic horizontal structure 4 can realize telescopic and fine adjustment in the horizontal direction to adapt to workpieces of different sizes and shapes. The polishing and polishing structure 5 includes a swing assembly 50 and a polisher main body 51. The fixed end of the swing assembly 50 is connected to the telescopic horizontal structure 4, and the swing section is connected to the polisher main body 51. The swing assembly 50 realizes swinging through the driving mechanism to adapt to the curvature change of the workpiece surface. The polisher main body 51 is responsible for the actual polishing and polishing work, which can use different polishing tools such as grinding wheel, abrasive belt and grinding head, and removes burrs, oxidation layer, etc. on the surface of the workpiece through high-speed rotation or reciprocating motion.

[0048] In operation, first, the device is moved near the workpiece to be polished by the base trolley 1. Then, the polishing and polishing structure 5 is adjusted to the appropriate position and angle through the cooperation of the vertical sliding platform structure 3 and the telescopic horizontal structure 4. Next, the swing assembly 50 and the polisher main body 51 are started to begin polishing and polishing the workpiece. During polishing, the swing frequency and amplitude of the swing assembly 50 and the speed and feed rate of the polisher main body 51 can be adjusted as needed to achieve the best polishing effect.

[0049] In practical application, in order to improve the automation degree and polishing precision of the device, an intelligent control system is usually equipped.

The first driven wheel 33 and the first fixed block 34 serve to position and support the synchronous belt. When the first motor 35 rotates forward or reversely, the sliding saddle 31 will correspondingly ascend or descend, thereby driving the telescopic horizontal structure 4 and the polishing structure 5 connected thereto to adjust in the vertical direction.

[0052] In some alternative embodiments, the telescopic horizontal structure 4 comprises a first telescopic arm 40 and a second telescopic arm 41. The first telescopic arm 40 is movably connected with the vertical sliding structure 3, and one end of the second telescopic arm 41 extends into the sliding cavity of the first telescopic arm 40 to telescopically move. When the transmission mechanism is activated, the second telescopic arm 41 will telescopically move in the first telescopic arm 40, thereby driving the polishing structure 5 connected thereto to adjust in the horizontal direction.

[0053] In some alternative embodiments, the telescopic horizontal structure 4 further comprises a second motor 42, a second gear 43, and a second rack 44. The second motor 42 drives the second gear 43 to rotate, and the second gear 43 meshes with the second rack 44, thereby driving the second telescopic arm 41 to telescopically move in the first telescopic arm 40; when the second motor 42 rotates forward or reversely, the second gear 43 will move along the second rack 44, thereby pushing the second telescopic arm 41 to telescopically move.

[0054] In some alternative embodiments, the telescopic horizontal structure 4 further comprises a third sliding rail 45 and a third sliding block 46. The third sliding rail 45 is fixedly arranged along the length direction of the second telescopic arm 41, and the third sliding block 46 is arranged in the sliding cavity of the first telescopic arm 40 and slidably connected with the third sliding rail 45.

The third motor 470 drives the third driving wheel 471 to rotate, and the third driving wheel 471 drives the second telescopic arm 41 to telescopically move in the first telescopic arm 40 through the third synchronous belt 473. The third driven wheel 474 serves to position and support the synchronous belt. The third fixed block 472 is fixedly connected with the second telescopic arm 41 and the third synchronous belt 473, ensuring the stability of the telescopic movement.

[0056] In some optional embodiments, the swing assembly 50 comprises a base plate 500, a fourth motor 501, a reversing shaft 502, and an extension cylinder 503. The fourth motor 501 drives the reversing shaft 502 to rotate, and the output ends of the reversing shaft 502 are arranged on both sides and fixedly connected with the extension cylinder 503. When the reversing shaft 502 rotates, it drives the extension cylinder 503 to swing in the horizontal plane. The driving rod of the extension cylinder 503 is fixedly connected with the polishing machine body 51, so that the polishing machine body 51 swings with the extension cylinder 503 to adapt to the curvature change of the workpiece surface.

[0057] In some optional embodiments, the leveling assembly 52 comprises an adjusting rotating shaft 520, a balance lifting rod 521, and a fixed plate 522. The swing end of the swing assembly 50 is fixedly connected with the adjusting rotating shaft 520, and the adjusting rotating shaft 520 is perpendicular to the rolling direction of the polishing machine body 51. When the polishing machine body 51 is in the process of polishing, the curvature of the workpiece surface changes constantly, and the polishing machine body 51 can swing along the adjusting rotating shaft 520 to adapt to the curvature change of the workpiece surface. When the polishing machine body 51 inclines during the swinging process, the balance lifting rod 521 extends and retracts to ensure the stability of the polishing machine body 51 during the working process.

[0058] In some optional embodiments, the dust collection structure 7 comprises a dust collection pipeline 70 and a dust collector body 71. The dust collector body 71 is connected with one side of the polishing machine body 51 through the dust collection pipeline 70. During the polishing process, the suction force generated by the dust collector body 71 can suck the generated dust and debris into the dust collection pipeline 70, and then discharge them after filtration. In this way, environmental pollution can be reduced and the health of the operator can be protected.

[0059] In some optional embodiments, the intelligent control structure 8 comprises a controller, a sensor, and an actuator. The intelligent control structure 8 is electrically connected with the vertical sliding table structure 3, the telescopic horizontal structure 4, the polishing and grinding structure 5, etc. Through the preset program and algorithm, the intelligent control structure 8 can realize the automatic control of the entire device.
