[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A pipe inner wall burr polishing mechanism includes a base plate 16. A first connecting frame 1 is bolted to the top of the base plate 16. A support assembly 3 is provided on the top of the first connecting frame 1. The support assembly 3 includes a first support block 301 and a plurality of second support blocks 302. A plurality of support wheels 303 are rotatably connected to the top of the second support blocks 302. A plurality of first electric push rods 304 are bolted to the bottom inner wall of the first connecting frame 1. The top of the first electric push rod 304 is fixedly connected to the bottom of the second support block 302. A second electric push rod 305 is bolted to the bottom inner wall of the first connecting frame 1. The top of the second electric push rod 305 is fixedly connected to the bottom of the first support block 301. Driven by the first electric push rod 304, the second support block 302 and the support wheels 303 on it move up and down. Driven by the second electric push rod 305, the first support block 301 and the transmission wheel 14 on it move up and down until the support wheel 303 and the transmission wheel 14 are in contact with the outer surface of the pipe, thereby providing stable support for the pipe.

[0025] A second connecting frame 2 is bolted to the top of the base plate 16. A connecting seat 4 is provided on the top of the second connecting frame 2. A second motor 11 is bolted to the outer wall of one end of the connecting seat 4. A threaded rod 5 is keyed to the output end of the second motor 11. The other end of the threaded rod 5 is rotatably connected to the inner wall of one end of the connecting seat 4. A sliding frame 7 is threaded onto the outer wall of the threaded rod 5. A first motor 9 is bolted to the inner wall of the top of the sliding frame 7. A grinding wheel 8 is keyed to the output end of the first motor 9. The grinding wheel 8 rotates under the drive of the first motor 9, thereby grinding the inner wall of the pipe. Two guide rods 6 are welded between the inner walls of the two ends of the connecting seat 4. The sliding frame 7 slides on the two guide rods 6. The threaded rod 5 rotates under the drive of the second motor 11, thereby causing the sliding frame 7 to move along the guide rods 6, which in turn drives the first motor 9 and the grinding wheel 8 to move. This causes the grinding wheel 8 to extend into the pipe and push forward to grind, thereby thoroughly deburring the inner wall of the pipe.

[0026] Multiple third electric push rods 10 are fixed to the bottom inner wall of the second connecting frame 2 by bolts. The top of the third electric push rod 10 is fixedly connected to the bottom of the connecting seat 4. Under the contraction of the third electric push rod 10, the connecting seat 4 is driven to move downward, thereby driving the sliding frame 7, the first motor 9 and the grinding wheel 8 to move downward, so that the grinding wheel 8 contacts the inner wall of the pipe.

[0027] Guide grooves 12 are provided on one side of the first support block 301 and one side of the second support block 302. Multiple sliding blocks 13 are integrally formed on the other side of the first support block 301 and the other side of the second support block 302. The sliding blocks 13 of the first support block 301 are slidably engaged with the adjacent second support block 302. The sliding blocks 13 of two adjacent second support blocks 302 are slidably engaged with the guide grooves 12, so that the first support block 301 and the multiple second support blocks 302 form a whole, thereby providing stable support for the pipeline.

[0028] The top of the first support block 301 is fixed with a third motor 15 by bolts. The output end of the third motor 15 is keyed to a transmission wheel 14. Driven by the third motor 15, the transmission wheel 14 rotates, and with the auxiliary support of the support wheel 303, the pipe rotates, thereby grinding and deburring along the inner circumference of the pipe. The top of the bottom plate 16 is welded with a support cylinder 17. Both sides of the outer wall of the support cylinder 17 are fixed with multiple fourth electric push rods 18 by bolts. The top of the multiple fourth electric push rods 18 is fixed with the same top plate 19 by bolts. The bottom of the top plate 19 is rotatably connected with multiple limit wheels 20. When the fourth electric push rods 18 retract, they drive the top plate 19 to move downward, thereby driving the limit wheels 20 to move downward and press on the pipe, thereby fixing the pipe. The bottom of the top plate 19 is welded with a sliding plate 21. The bottom end of the sliding plate 21 is slidably inserted into the top end of the support cylinder 17, thereby guiding the movement of the top plate 19.

[0029] The working principle of this embodiment is as follows: In use, firstly, the pipe is placed on the transmission wheel 14 and located between the support wheels 303 of the multiple second support blocks 302. Then, the first electric push rod 304 and the second electric push rod 305 are activated. Under the drive of the first electric push rod 304, the second support block 302 and the support wheel 303 on it move up and down. Then, under the drive of the second electric push rod 305, the first support block 301 and the transmission wheel 14 on it move up and down until the support wheel 303 and the transmission wheel 14 are in contact with the outer surface of the pipe, thereby providing stable support for the pipe. Next, the fourth electric push rod 18 is activated. Under the retraction of the fourth electric push rod 18, the top plate 19 moves downward, thereby causing the limiting wheel 20 to move downward and press on the pipe, thereby fixing the pipe.

[0030] Then, the second motor 11 is started, and the threaded rod 5 rotates under the drive of the second motor 11, causing the sliding frame 7 to move along the guide rod 6, which in turn drives the first motor 9 and the grinding wheel 8 to move, so that the grinding wheel 8 extends into the pipe. Next, the third electric push rod 10 is started, and the connecting seat 4 moves downward under the contraction of the third electric push rod 10, which in turn drives the sliding frame 7, the first motor 9 and the grinding wheel 8 to move downward, so that the grinding wheel 8 contacts the inner wall of the pipe. Then, the first motor 9 is started, and the grinding wheel 8 rotates under the drive of the first motor 9, so as to grind the inner wall of the pipe. At the same time, the third motor 15 is started, and the transmission wheel 14 rotates under the drive of the third motor 15. With the auxiliary support of the support wheel 303, the pipe rotates, so as to grind and deburr along the circumferential inner wall of the pipe. During this process, the grinding wheel 8 moves under the rotation of the threaded rod 5 driven by the second motor 11, so as to push forward for grinding, and thus thoroughly deburr the inner wall of the pipe.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
