[0019] Compared with the prior art, the pipeline polishing device of the present invention has the following beneficial effects:

[0020] 1. By connecting the shifting mechanism with the support seat assembly, the first lifting mechanism is installed on one side of one end of the shifting mechanism, and the second lifting mechanism is installed on the other side of the other end of the shifting mechanism, so that the shifting mechanism can drive the support seat assembly and the pipe body placed on the support seat assembly to move, so that the pipe body can be opposite to the inner circle grinding mechanism, so that the inner circle grinding mechanism can grind the inner wall of the pipe body; at the same time, the pipe body can be opposite to the inner support rotating mechanism, and then the inner support rotating mechanism can be embedded in the pipe body, so that the inner support rotating mechanism can drive the pipe body to rotate; and, by installing the third translation mechanism on the outside of the shifting mechanism close to one end of the second translation mechanism, so that the second translation mechanism can drive the outer circle grinding mechanism to move, so that when the inner support rotating mechanism drives the pipe body to rotate, the outer grinding mechanism can grind the outer wall of the pipe body. By enabling the inner circle grinding mechanism to grind the inner wall of the pipe body, enabling the outer circle grinding mechanism to grind the outer wall of the pipe body, and enabling the displacement mechanism to drive the pipe body to move, it is possible to complete the grinding of the inner and outer walls of the pipe body in succession after completing one lifting of the pipe body, thereby improving the grinding efficiency of the pipe body.

[0021] 2. By installing the first motor on the displacement plate, installing the first gear on the outside of the first output shaft of the first motor, and engaging the first gear with the rack, the first motor can drive the first gear to rotate, thereby enabling the first gear to engage the rack to move, thereby providing power for the displacement plate to move on the first guide rail.

[0022] 3. By setting the accommodating groove in the support seat body, embedding multiple first support rollers into the accommodating groove, and making the multiple first support rollers rotatably connected to the support seat body, it is possible to achieve that the support seat body can support the multiple first support rollers, so that the multiple first support rollers can rotate in the accommodating groove, and then the support seat body can support the pipeline body through the multiple first support rollers, so as to improve the rotation flexibility of the pipeline body.

[0023] 4. By installing the first electric push rod on the first lifting plate and connecting the output end of the first electric push rod to the first translation stage, the first electric push rod can drive the first translation stage to move, thereby adjusting the position of the first translation stage.

[0024] 5. When the first electric push rod drives the first translation table to move, and the inner cylindrical grinding mechanism is embedded in the pipe body (at this time the inner cylindrical grinding mechanism is already in contact with the inner wall of the pipe body), the second motor is started to drive the first rotating shaft to rotate, thereby causing the first rotating shaft to drive the third gear to rotate; when the third gear rotates, the third gear drives the first telescopic cylinder to rotate through the second gear; since the spline body on the outer wall of the second telescopic cylinder is embedded in the spline groove on the inner wall of the first telescopic cylinder, when the first telescopic cylinder rotates, the first telescopic cylinder will drive the second telescopic cylinder to rotate; at the same time, when the first rotating shaft rotates, the first rotating shaft will drive the first lead screw to rotate through the first synchronous wheel, the second synchronous wheel and the first synchronous belt, thereby causing the first lead screw to drive the second telescopic cylinder to move inside the first telescopic cylinder, thereby realizing that the second telescopic cylinder drives the inner cylindrical grinding mechanism to rotate and move, so that the inner cylindrical grinding mechanism grinds the inner wall of the pipe body.

[0025] 6. When the second telescopic cylinder drives the grinding cylinder to embed into the pipe body, the third motor is started, so that the third motor drives the second lead screw to rotate, thereby causing the second lead screw to drive the two first adjusting blocks to move relative to each other, and then the two first adjusting blocks drive the grinding plate to move away from the grinding cylinder through the first connecting rod, so that the grinding brush and the universal roller fit the inner wall of the pipe body to adapt to pipe bodies of different diameters, thereby improving the applicability of the product; when the second telescopic cylinder rotates and moves, the second telescopic cylinder will drive the grinding cylinder to rotate and move, and at this time the grinding cylinder will drive the universal roller and the grinding brush to rotate and move, so that the grinding brush grinds the inner wall of the pipe body.

[0026] 7. By installing the second electric push rod on the second lifting plate and connecting the output end of the second electric push rod to the second translation stage, the second electric push rod can drive the second translation stage to move, thereby adjusting the position of the second translation stage.

[0027] 8. When the inner support tube is embedded in the pipe body, start the third electric push rod, so that the third electric push rod drives the second adjusting block to move, so that the second adjusting block drives the inner support plate to move through the second connecting rod, and then the inner support plate fits with the inner wall of the pipe body through the friction protrusion; then, start the fourth motor, so that the fourth motor drives the inner support tube to rotate through the fifth gear and the fourth gear, so that the inner support tube drives the inner support plate to rotate, and then drives the pipe body to rotate, so that the outer circle grinding mechanism can grind the outer wall of the pipe body.

[0028] 9. By setting a second threaded hole in the third translation stage and passing the third lead screw through the second threaded hole, the third lead screw is threadedly connected to the third translation stage, thereby rotating the third lead screw to drive the third translation stage to move; by connecting the two ends of the first optical bar to the two first fixed plates respectively, and passing the first optical bar through the third translation stage, the two first fixed plates cooperate to support the first optical bar, thereby enabling the third translation stage to move along the first optical bar, thereby improving the stability of the movement of the third translation stage.

[0029] 10. By connecting the two ends of the third rotating shaft to a first pulley and a second pulley respectively, the third rotating shaft can be rotated, so that the third rotating shaft drives the first pulley and the second pulley to rotate, thereby driving the first sanding belt and the second sanding belt to rotate synchronously; by making the mesh number of the first sanding belt smaller than the mesh number of the second sanding belt, when grinding the outer wall of the pipe body, the first sanding belt is first used to grind the outer wall of the pipe body, and then the second sanding belt is used to grind the outer wall of the pipe body, so that the first sanding belt first performs rough processing on the outer wall of the pipe body, and then the second sanding belt performs fine processing on the outer wall of the pipe body, so as to improve the efficiency of grinding the outer wall of the pipe body.

[0030] 11. By passing the fourth lead screw through the third threaded hole of the fourth translation stage, the fourth lead screw is threadedly connected to the fourth translation stage, thereby rotating the fourth lead screw to drive the fourth translation stage to move, so as to adjust the distance between the fourth translation stage and the displacement mechanism; by installing the clamping seat at the bottom of the fourth lifting plate and setting the clamping groove in the clamping seat, the fourth lifting plate can drive the clamping seat to move up and down, so that the pipeline body is embedded in the clamping groove, and then the clamping seat presses the pipeline body on the support seat assembly to avoid the pipeline body from rotating when the inner circle grinding mechanism grinds the inner wall of the pipeline body, so as to improve the grinding effect of the pipeline body.
