[0020] Embodiment 1

[0021] Please refer to Figure 1 , a surface grinding device for a butt - joint elbow, comprising a base 1. A wall panel 2 is connected to the rear side of the base 1, and a top plate 3 is connected to the wall panel 2. An arc - shaped positioning groove 4 is provided on the base 1. Side pressing mechanisms are provided on both sides of the positioning groove 4 on the base 1. Specifically, the side pressing mechanism includes a second cylinder 6 fixed on the base and a side pressing block 7 connected to the telescopic end of the second cylinder. The two side pressing blocks 7 are located on both sides of the positioning groove 4. An upper pressing mechanism is provided on the top plate. Specifically, the upper pressing mechanism includes a third cylinder 8 connected to the top plate and an upper pressing block 9 connected to the telescopic end of the third cylinder. The lower part of the upper pressing block 9 is triangular so that the upper pressing block 9 can press on the inner angle of the elbow. The upper pressing block 9 is located directly above the positioning groove 4. Place the elbow 10 in the positioning groove 4, then control the extension of the second cylinders 6 on both sides to drive the relative movement of the two side pressing blocks 7. During this process, adjust the extension lengths of the two second cylinders 6 so that the elbow can be located directly above the upper pressing block 9. Then control the extension of the third cylinder 8 to drive the upper pressing block 9 to descend and tightly press the elbow in the positioning groove 4, thereby fixing the elbow from the side and the top.

[0022] Grinding units 5 are provided on both sides of the upper pressing mechanism on the top plate 3, and the two grinding units 5 are symmetric with respect to the upper pressing mechanism.

[0023] Specifically, as Figure 2As shown in the figure, the grinding unit 5 includes a hinge seat 501 fixed on the top plate, a first cylinder 502 hinged to the hinge seat, a drive box 503 connected to the first cylinder, a rotating shaft 504 rotatably connected to the drive box, a grinding cylinder 505 connected to the rotating shaft, and a drive mechanism disposed in the drive box and controlling the rotation of the rotating shaft. The drive mechanism includes a motor 508 disposed in the drive box, a transmission shaft connected to the motor through a coupling, a main gear 509 connected to the transmission shaft, and a sub-gear 510 connected to the rotating shaft. The main gear 509 meshes with the sub-gear 510. When the motor 508 operates, it drives the transmission shaft to rotate. Through the cooperation of the main gear 509 and the sub-gear 510, the rotating shaft 504 is driven to rotate, thereby driving the grinding cylinder 505 to rotate.

[0024] The inner wall of the grinding cylinder 504 is connected with a grinding block 506 and a cleaning brush 507 from the inside to the outside. During the rotation of the grinding cylinder 505, the cleaning brush 507 will be driven to rotate to clean the elbow, and at the same time, the grinding block 506 will be driven to rotate to grind the elbow.

[0025] The grinding unit 5 further includes a deflection mechanism for driving the first cylinder 502 to rotate. The deflection mechanism is a fourth cylinder 511 hinged to the top plate. The telescopic end of the fourth cylinder 511 is hinged to the cylinder body of the first cylinder 502. By the operation of the fourth cylinder 511, the first cylinder 502 can be driven to deflect, thereby adjusting the angle of the grinding cylinder 505 to adapt to elbows at different angles.

[0026] The working principle of this embodiment is as follows: The elbow 10 is fixed in the positioning groove 4. Before grinding, the first cylinder 502 extends, driving the grinding cylinder 505 to move towards the elbow and making the cleaning brush 507 sleeve on the elbow. Then, the rotating shaft 504 is controlled to rotate through the drive mechanism, driving the grinding cylinder 505 to rotate to clean the part to be ground. Then, the first cylinder 502 continues to extend, making the grinding block 506 contact the elbow, and the elbow is ground by the rotation of the grinding block 506. After grinding, the first cylinder 502 contracts, driving the grinding cylinder 505 to move outwards, and the remaining debris after grinding is cleaned again through the cleaning brush 50. Finally, the grinding cylinder is completely separated from the elbow.
