[0040] In the present embodiment, the rotating mechanism comprises an integral limiting disc 41 and a toothed disc 42, the circumference of the limiting disc 41 is provided with an annular limiting groove 44, the circumference of the toothed disc 42 is provided with meshing teeth 43, the surface of the moving base plate 4 is provided with a plurality of limiting wheels 45 and a driving gear 48, the plurality of limiting wheels 45 always cooperate with the annular limiting groove 44, at least one driving gear 48 meshes with the toothed disc 42, in use, the driving gear 48 operates, the whole (the limiting disc 41 and the toothed disc 42) rotates through the meshing teeth 43, and the motor 1 33 operates to make the moving base plate 4 translate; so that the whole moves and rotates at the same time, thereby improving the polishing area of the pipe.

[0041] Wherein the moving base plate 4, the limiting disc 41 and the toothed disc 42 are all provided with the same size notches 46, the notches 46 are provided with first polishing belts 47, the inner walls of the limiting disc 41 and the toothed disc 42 are provided with second polishing belts (not shown in the figure), in use, the outer wall of the pipe to be polished 8 always contacts the inner walls (second polishing belts) of the limiting disc 41 and the toothed disc 42.

[0042] Please refer to Figure 7Since the limiting disc 41 and the tooth disc 42 have the notch 46, the whole is in the shape of "C", and the first polishing belt 47 is arranged at the notch 46, when the pipe 8 to be polished contacts the first polishing belt 47, the first polishing belt 47 can tighten the pipe 8 to be polished at the notch 46, and the contact strength of the pipe 8 to be polished and the first polishing belt 47 is improved, so that the polishing quality is improved; that is, when the limiting disc 41 and the tooth disc 42 rotate, the pipe 8 to be polished contacts the first polishing belt 47 or the second polishing belt, so that the polishing blind area is avoided in the rotating process, and the polishing quality is improved.

[0043] Based on the above embodiment, the limiting disc 41 and the tooth disc 42 can also be complete annular, the pipe 8 to be polished is inserted into the limiting disc 41 and the tooth disc 42 at the through hole 34, and after the height is adjusted, the outer wall of the pipe 8 to be polished still contacts the inner wall of the limiting disc 41 and the tooth disc 42, so that the moving polishing and polishing are realized.

[0044] In order to ensure the stability of the pipe 8 to be polished when polishing, one end of the pipe to be polished is provided with a mouth opening fixing mechanism, and the specific reference is made to Figure 9-11 The mouth opening fixing mechanism comprises a plurality of arrayed extension rods 54, the plurality of extension rods 54 are arranged in a circumferential array and are supported on the inner wall of the port of the pipe 8 to be polished, and the other end is pulled by the U-shaped limiting rod 36, the U-shaped limiting rod 36 is rotationally connected with the fixed cylinder 35 penetrating through the vertical plate 3, and the fixed cylinder 35 is fixed on the outer side of the vertical plate 3; at this time, one end of the pipe 8 to be polished is supported by the plurality of extension rods 54, and the other end is pulled by the U-shaped limiting rod 36, so that the stability is maintained, and the shaking or rotation of the pipe 8 to be polished when the rotating mechanism polishes is avoided.

[0045] Please refer to Figure 1-3 again, the two ends of the pipe 8 to be polished are in the through hole 34, at this time, the outer wall of the pipe in the through hole 34 cannot be polished, so that the blind area is generated; in order to make the pipe circumference be polished and avoid the polishing blind area, the recess cavity 541 is arranged on the extension rod 54, a plurality of electric driving wheels 542 are arranged in the recess cavity 541, the circumference of the electric driving wheel 542 always contacts the inner wall of the pipe 8 to be polished; when the outer wall of the pipe in the through hole 34 cannot be polished, the driving wheel 542 rotates, so that the pipe 8 to be polished moves forward and backward, so that the outer wall of the pipe in the through hole 34 leaks out, and after leaking out, the inner wall of the limiting disc 41 and the tooth disc 42 contacts the outer wall of the pipe, so that the complete polishing and polishing of the outer wall of the pipe are realized.

[0046] When the pipe 8 to be polished moves forward and backward, the other end of the pipe 8 to be polished always does not escape from the pull of the U-shaped limiting rod 36; the falling of the pipe 8 to be polished is prevented.

[0047] Further, in order to improve the application range of the equipment, satisfy the pipes with various diameters, please refer to Figure 12-13The supporting mechanism further comprises a box 5 and an auxiliary lifting vertical plate 51 vertically arranged in the box 5, a plurality of interconnected grooves 52 are arranged in the auxiliary lifting vertical plate 51, a sliding block 53 is arranged in the groove 52, the sliding block 53 can move in the groove 52, a compression spring 543 is arranged between the sliding block 53 and the inner wall of the groove 52, the sliding block 53 can compress or stretch the compression spring 543 when moving in the groove 52, and the end of the extension rod 54 is fixed on the sliding block 53, and the extension rod 54 can adapt to pipelines with different diameters when a plurality of sliding blocks 53 are simultaneously expanded or tightened.

[0048] That is, the position of the sliding block 53 changes, and the position of the extension rod 54 changes accordingly; the positions of a plurality of sliding blocks 53 change simultaneously, and the positions of the corresponding extension rods 54 change accordingly; when simultaneously expanded, a plurality of extension rods 54 can support a pipeline with a larger diameter; when simultaneously tightened, a plurality of extension rods 54 can support a pipeline with a smaller diameter, so that pipelines with different diameters can be supported, and the application range of the equipment is improved.

[0049] When the overall pipeline with different diameters is adapted, the outer wall of the pipeline (the pipeline to be polished 8) cannot contact the outer wall of the limiting disc 41 and the tooth disc 42, and polishing and polishing cannot be achieved; therefore, while adapting the pipeline with different diameters, the overall height of the pipeline to be polished 8 also needs to be adjusted. Therefore, a strip-shaped sliding block 55 is arranged on both sides of the auxiliary lifting vertical plate 51, a sliding groove matched with the strip-shaped sliding block 55 is arranged on the inner wall of the box 5, and the auxiliary lifting vertical plate 51 is lifted by cooperation of the strip-shaped sliding block 55 and the sliding groove.

[0050] In order to realize automatic matching of the pipe diameter and automatic lifting of the auxiliary lifting vertical plate 51, a moving base 6 is arranged on the outer side of the box 5, a sliding rail (not shown in the figure) matched with the moving base 6 is arranged on the workbench 2, the moving base 6 is translated by a cylinder one 61, the end of the cylinder one 61 is fixed on the outer side of the vertical plate 3, a main lifting vertical plate 62 is arranged above the moving base 6, a cylinder two 65 is arranged in the inner concave surface of the moving base 6, a second optical axis 621 is symmetrically arranged on both sides of the cylinder two 65, a jacking rod 63 is arranged on the side close to the auxiliary lifting vertical plate 51 of the main lifting vertical plate 62, a plurality of arc-shaped fins 64 are arranged on the circumference of the jacking rod 63, and the arc-shaped fins 64 push the sliding block 53 to move in the groove 52 and press the compression spring 543 when the main lifting vertical plate 62 moves towards the auxiliary lifting vertical plate 51.

[0051] The extension rod 54 is always located inside the intersection of a plurality of grooves 52, and the arc-shaped fins 64, the grooves 52 and the sliding blocks 53 are one-to-one corresponding.

[0052] When the cylinder one 61 pulls the moving base 6, the moving base 6 and the main lifting stand 62 move together to the direction of the auxiliary lifting stand 51, at this time the push rod 63 and the arc fin 64 further extend to the intersection of the plurality of grooves 52, because the height of the edge of the arc fin 64 gradually rises, so the rising arc can push the corresponding slider 53, at this time the slider 53 moves outward, when the slider 53 moves outward, the extension rod 54 moves with it, at this time the plurality of extension rods 54 can support the pipeline with a larger diameter; similarly, when the cylinder one 61 pushes the moving base 6, the push rod 63 and the arc fin 64 push the auxiliary lifting stand 51, at this time the extension of the compression spring 543 can push the slider 53 to move inward, at this time the pipeline with a smaller diameter can be supported.

[0053] When the inner wall of the pipeline is stably supported, the extension and retraction of the cylinder two 65 can drive the main lifting stand 62 to rise and fall; because the push rod 63 is always located inside the intersection of the plurality of grooves 52, so the lifting of the push rod 63 can also drive the auxiliary lifting stand 51 to rise and fall, so that the main lifting stand 62 and the auxiliary lifting stand 51 are synchronous, so as to ensure that the outer wall of the pipeline to be polished 8 contacts the inner wall of the limiting disc 41 and the tooth disc 42, and meets the polishing contact requirement.

[0054] Please refer to Figure 14-17 , in order to realize the polishing of the front and back of the plate to be polished 9, the surface of the workbench 2 is provided with two parallel strip-shaped grooves 21, the inner wall of the strip-shaped groove 21 is provided with a sliding groove 211, and a recess 22 is arranged between the two strip-shaped grooves 21, one of the recesses 22 is provided with a U-shaped plate 23, the strip-shaped groove 21 is provided with a turnover wheel 24 at the end away from the U-shaped plate 23, the turnover wheel 24 is provided with an arc-shaped groove 241, the arc-shaped groove 241 is provided with a limiting shaft 242 matched with the sliding groove 211, and the circumference of the turnover wheel 24 is provided with a clamping groove 243; wherein the end of the front driving arm 71 is hinged to the outer wall of the U-shaped plate 23, and the height of the inner opening of the U-shaped plate 23 and the height of the clamping groove 243 are respectively consistent with the thickness of the plate to be polished 9.

[0055] In use, the plate to be polished 9 can be moved to one side by the polishing roller 39 and the roller 38; when the plate to be polished 9 is separated from the roller 38, the upper surface is polished and polished; then one side of the plate enters the U-shaped plate 23, and the other side enters the clamping groove 243; then the mechanical arm 7 lifts the U-shaped plate 23 and pulls it to the direction of the turnover wheel 24.

[0056] As Figure 18As shown, in the pulling process, the position of the U-shaped plate 23 is constantly raised and moves towards the direction of the turnover wheel 24, while the turnover wheel 24 slides in the sliding groove 211 through the limiting shaft 242 and slides towards the direction of the mechanical arm 7; with the further extension of the mechanical arm 7, the to-be-polished plate 9 can be turned over by 180°, so that the surface not polished and polished can be exposed; finally, the to-be-polished plate 9 is pushed again towards the direction of the polishing roller 39, so that the front and back surfaces can be polished.

[0057] In some embodiments, the extension end of the plurality of polishing rollers 39 is provided with a synchronous wheel, the plurality of synchronous wheels are connected through a synchronous belt, and one of the synchronous wheels is connected with an external stepping motor; when the polishing surface is changed, the stepping motor changes the direction.

[0058] In some embodiments, the pipeline polishing and polishing work and the plate polishing and polishing work can be operated separately or simultaneously.
