Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

It is a relatively mature technology and will not be described here. In order to ensure the stability of the processing table 1, a support leg 2 is welded at its bottom, and a fixed support foot that increases friction is welded at the bottom of the support leg 2 to ensure stability.

[0024] See also Figure 1-Figure 6In order to facilitate the sufficient polishing of the outer surface of the pipe body 22 to avoid dead angles and adapt to the processing of pipe bodies 22 of different shapes to improve practicality, the processing table 1 is equidistantly and vertically installed with hydraulic telescopic rods 3 of the adjustment mechanism, and the top of the hydraulic telescopic rod 3 (i.e., the output end) is jointly installed with a lifting plate 4, and the bottom of the lifting plate 4 is installed with two sets of linear guide devices 5, and the linear guide device 5 is slidably matched with a guide slider 9 (which can be driven by a linear motor or can be reciprocated by a reciprocating screw rod to achieve reciprocating movement of the guide slider 9, which is a relatively mature technology and will not be described in detail here), and the two guide sliders A movable plate 10 of a buffer reset assembly is fixedly installed between the blocks 9 by bolts, a guide telescopic rod 13 is vertically installed in the middle of the bottom end of the movable plate 10, a spring 14 is sleeved on the outside of the guide telescopic rod 13, and a rotating ball 16 of a rotating assembly is installed at the bottom, and a rectangular block 15 can be fixedly installed on the top of the grinding block 11 of the grinding assembly by bolts, and an empty groove is opened on the top of the rectangular block 15 to facilitate the rotation of the rotating ball 16, and a grinding belt 12 is bonded to the inner arc surface of the grinding block 11, which can facilitate the grinding operation of the pipe body 22, and can always contact and fit with its outer surface during the grinding process to ensure the grinding effect and avoid grinding dead corners.

[0025] See also Figure 1-Figure 6 In order to facilitate the clamping and fixing of the pipe body 22 and to rotate it for the convenience of grinding operation, slide grooves 8 of the moving components are provided at both ends of the processing table 1, and a sliding block 21 is arranged inside the slide groove 8 through an electric push rod 20, which can slide back and forth in the slide groove 8, and a vertical plate 6 is fixedly arranged between the two sliding blocks 21 at the same end, and a through hole is opened on the vertical plate 6 for convenient installation of the motor 7, and the output end of the motor 7 is fixedly connected to the rotating ball 16 of the rotating component through a coupling, and a rectangular block 15 of the rotating component is also welded to one side wall of the transfer plate 17 in the clamping component (the same structure as the rectangular block 15 on the grinding block 11), and a plug-in rod 18 is horizontally welded to the other side wall of the transfer plate 17, which can facilitate the plug-in of the two ends of the pipe body 22, and a rubber sleeve 19 is bonded to the outside of the plug-in rod 18 to avoid hard contact.

[0026] Working principle: When the utility model is in use, the pipe body 22 to be processed is first plugged and fixed with the plug-in rod 18 at one end, and is initially fixed under the action of the rubber sleeve 19, and then the electric push rod 20 is retracted, and the sliding block 21 slides in the slide groove 8, and the two vertical plates 6 are brought closer to each other. During the movement, the inclination angle of the rotating plate 17 at the other end can be adjusted by rotating the rotating ball 16 and the rectangular block 15, so that the other end of the pipe body 22 can be plugged in conveniently (when it is a straight line, the two rotating plates 17 are kept in a horizontal state). After the adjustment is completed, the movement continues, and the other end can be plugged and fixed, thereby completing the fixation of the pipe body 22. At this time, the hydraulic telescopic rod 3 is retracted, and the lifting plate 4 moves downward. At this time, the grinding belt 12 under the grinding block 11 is in contact with the pipe body 2 2 outer surface, as it continues to move downward, an upward squeezing force is generated on it, and the guide telescopic rod 13 and the spring 14 shrink accordingly to store potential energy. At this time, the motor 7 works to drive the rotating plate 17 to rotate, and then the pipe body 22 can be slowly rotated. At this time, the pipe body 22 can be polished by the polishing belt 12. At this time, the linear guide device 5 works to drive the guide slider 9 and the moving plate 10 to move slowly, and then the polishing block 11 and the polishing belt 12 can be moved, and then the outer surface of the pipe body 22 can be polished. Due to the guide telescopic rod 13 and the spring 14, as well as the rotating ball 16 and the rectangular block 15, it can be ensured that during the mobile polishing process, it can always be in contact with the surface of the pipe body 22, thereby ensuring that the polishing is fully and evenly, and avoiding the existence of polishing dead angles.
