DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-3, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0022] As shown in the figure, a polishing device for stainless steel pipe production includes a frame 1. A driving mechanism 2 and a polishing mechanism 3 are arranged on the frame 1. The driving mechanism 2 includes driving rollers 21 and a first motor 22. The two driving rollers 21 are horizontally distributed and rotatably arranged on the frame 1. The first motor 22 is arranged on the frame 1 and is in transmission connection with the driving rollers 21. The polishing mechanism 3 includes an inner polishing assembly 31 and an outer polishing assembly 32. The inner polishing assembly 31 includes an inner sliding rod 311 and an inner polishing block 312. The inner sliding rod 311 is slidably arranged on the frame 1 along the length direction of the driving rollers 21. The inner polishing block 312 is arranged at the end of the inner sliding rod 311, and the inner polishing block 312 can move with the sliding rod and contact the inner wall of the stainless steel pipe placed between the two driving rollers 21. The outer polishing assembly 32 includes an outer sliding rod 321 and an outer polishing block 322. The outer sliding rod 321 is slidably arranged on the frame 1 along the length direction of the driving rollers 21. The outer polishing block 322 is arranged at the end of the outer sliding rod 321, and the outer polishing block 322 can move with the outer sliding rod 321 and contact the outer wall of the stainless steel pipe placed between the two driving rollers 21.

[0023] Specifically, the structures of the inner sliding rod 311 and the outer sliding rod 321 slidably arranged on the frame 1: Two linear slide rails 33 parallel to the driving rollers 21 are arranged on the frame 1. A sliding frame 34 is fixedly connected to the sliding seat of the linear slide rail 33. A transmission lead screw 35 that is screwed into the sliding frame 34 and is in transmission connection with a second motor 37 arranged on the frame 1 is rotatably arranged on the frame 1. The inner sliding rod 311 and the outer sliding rod 321 are fixedly connected to the sliding frame 34. Through the above structure, the second motor 37 drives the transmission lead screw 35 to rotate. The transmission lead screw 35 drives the sliding frame 34 to slide along the length direction of the driving rollers 21 on the linear slide rail 33 through the screw connection with the sliding frame 34. The sliding frame 34 drives the inner sliding rod 311 and the outer sliding rod 321 to slide on the frame 1 along the length direction of the driving rollers 21.

[0024] Specifically, a support seat 38 is arranged on the frame 1. The inner sliding rod 311 and the outer sliding rod 321 pass through the support seat 38. The support seat 38 plays a supporting role when the inner sliding rod 311 and the outer sliding rod 321 slide, ensuring the stability of the inner sliding rod 311 and the outer sliding rod 321 when sliding.

[0025] In the above embodiment, the stainless steel pipe to be polished is placed between two driving rollers 21 and abuts against the two driving rollers 21. The first motor 22 drives the two driving rollers 21 to rotate synchronously to drive the stainless steel pipe to rotate. At the same time, the second motor 37 drives the sliding frame 34 to drive the inner sliding rod 311 and the outer sliding rod 321 to move towards the stainless steel pipe. The inner sliding rod 311 and the outer sliding rod 321 respectively drive the inner polishing assembly 31 and the outer polishing assembly 32 provided at their ends to move towards the stainless steel pipe. The inner polishing block 312 is inserted into the stainless steel pipe along with the inner sliding rod 311 and contacts the inner wall of the stainless steel pipe. The outer polishing block 322 moves to one side of the outer wall of the stainless steel pipe along with the outer sliding rod 321 and abuts against the outer wall of the stainless steel pipe. With the rotation of the stainless steel pipe and the movement of the inner polishing block 312 and the outer polishing block 322 along the length direction of the driving rod, that is, along the length direction of the stainless steel pipe, the inner wall and the outer wall of the stainless steel pipe are polished simultaneously, saving manpower and improving production efficiency.

[0026] Preferably, the driving mechanism 2 further includes a lifting frame 23, a pressing wheel 24 and a pressing cylinder 25. The lifting frame 23 is longitudinally slidably arranged on the frame 1 above the gap between the two driving rollers 21. The pressing cylinder 25 is arranged on the frame 1 and the output shaft of the pressing cylinder 25 faces downward and is fixedly connected to the lifting frame 23. A plurality of the pressing wheels 24 are rotatably arranged on the lifting frame 23 and distributed along the length direction of the driving roller 21. After the stainless steel pipe to be polished is placed between the two driving rollers 21, the pressing cylinder 25 drives the lifting frame 23 to move downward so that the pressing wheel 24 abuts against the stainless steel pipe, enabling the stainless steel pipe to stably abut against the driving rollers 21, thereby ensuring the stability when the driving rollers 21 drive the stainless steel pipe to rotate, and further ensuring that the inner polishing block 312 and the outer polishing pipe can stably abut against the inner wall and the outer wall of the stainless steel pipe, ensuring the polishing quality.

[0027] Furthermore, the inner polishing assembly 31 further includes an inner mounting frame 313, a first inner connecting rod 314, a second inner connecting rod 315, an inner connecting sleeve 316 and an inner adjusting sleeve 317. The inner polishing block 312 is installed in the inner mounting frame 313. One end of the first inner connecting rod 314 is hinged to the inner mounting frame 313, and the other end is hinged to the inner sliding rod 311. The inner adjusting sleeve 317 is screwed on the inner sliding rod 311. The inner connecting sleeve 316 is rotatably arranged on the inner adjusting sleeve 317. One end of the second inner connecting rod 315 is hinged to the inner mounting frame 313, and the other end is hinged to the inner connecting sleeve 316;

[0028] The outer polishing assembly 32 further includes an outer mounting frame 323, a first outer connecting rod 324, a second outer connecting rod 325, an outer connecting sleeve 326, and an outer adjusting sleeve 327. The outer polishing block 322 is installed in the outer mounting frame 323. One end of the first outer connecting rod 324 is hinged to the outer mounting frame 323, and the other end is hinged to the outer sliding rod 321. The outer adjusting sleeve 327 is screwed onto the outer sliding rod 321. The outer connecting sleeve 326 is rotatably arranged on the outer adjusting sleeve 327. One end of the second outer connecting rod 325 is hinged to the outer mounting frame 323, and the other end is hinged to the outer connecting sleeve 326.

[0029] In the above preferred embodiment, by rotating the inner adjusting sleeve 317, it slides along the length direction of the inner sliding rod 311 on the inner sliding rod 311. The inner adjusting sleeve 317 drives the inner connecting sleeve 316 to slide along the length direction of the inner sliding rod 311. The inner connecting sleeve 316 drives the second inner connecting rod to swing and cooperates with the swing of the first inner connecting rod 314 to drive the inner polishing block 312 to move along the inner sliding rod 311, so as to adjust the distance between the inner polishing block 312 and the inner wall of the stainless steel pipe when the inner polishing block 312 is inserted into the stainless steel pipe along with the inner sliding rod 311. Similarly, by rotating the outer adjusting sleeve 327, the distance between the outer polishing block 322 and the outer wall of the stainless steel pipe can be adjusted. When the inner polishing block 312 and the outer polishing block 322 are severely worn, by adjusting the positions of the inner polishing block 312 and the outer polishing block 322, the inner polishing block 312 and the outer polishing block 322 are brought into contact with the stainless steel pipe, extending the service life of the inner polishing block 312 and the outer polishing block 322. Moreover, by adjusting the positions of the inner polishing block 312 and the outer polishing block 322, stainless steel pipes with different wall thicknesses can be adapted, having better applicability.

[0030] Preferably, an inner sliding section 3171 is formed on the circumferential surface of the inner adjusting sleeve 317. The inner connecting sleeve 316 is sleeved on the inner sliding section 3171. An inner buffer spring 3172 is sleeved on the inner sliding section 3171 between the inner connecting sleeve 316 and the inner adjusting sleeve 317. An outer sliding section 3271 is formed on the circumferential surface of the outer adjusting sleeve 327. The outer connecting sleeve 326 is sleeved on the outer sliding section 3271. An outer buffer spring 3272 is sleeved on the outer sliding section 3271 between the outer connecting sleeve 326 and the outer adjusting sleeve 327. Under the action of the inner buffer spring 3172, the inner connecting sleeve 316 has a tendency to drive the inner polishing block 312 to move towards the inner wall of the stainless steel pipe through the first inner connecting rod 314, so that the inner polishing block 312 has a certain adjustment space when it abuts against the inner wall of the stainless steel pipe, making the inner polishing block 312 more stably abut against the inner wall of the stainless steel pipe. Similarly, the outer polishing block 322 more stably abuts against the outer wall of the stainless steel pipe under the action of the outer buffer spring 3272, thus ensuring the polishing quality.

[0031] Preferably, an inner installation cavity 3131 matching the inner polishing block 312 is formed on the inner installation frame 313. The inner polishing block 312 is placed in the inner installation cavity 3131. An inner fastening bolt 3132 that penetrates into the inner installation cavity 3131 and abuts against the inner polishing block 312 is screwed on the inner installation frame 313. An outer installation cavity 3231 matching the outer polishing block 322 is formed on the outer installation frame 323. The outer polishing block 322 is placed in the outer installation cavity 3231. An outer fastening bolt 3232 that penetrates into the outer installation cavity 3231 and abuts against the outer polishing block 322 is screwed on the outer installation frame 323. By loosening the inner fastening bolt 3132, the inner polishing block 312 can be taken out of or placed into the inner installation cavity 3131, facilitating the disassembly and assembly of the inner polishing block 312. Similarly, the outer fastening bolt 3232 also facilitates the disassembly and assembly of the outer polishing block 322, thereby facilitating the replacement of the inner polishing block 312 and the outer polishing block 322 to ensure the polishing quality.

[0032] Preferably, two inner polishing blocks 312 are symmetrically arranged along the axis of the inner sliding rod 311, and two outer polishing assemblies 32 are symmetrically arranged along the axis of the inner sliding rod 311 to improve the polishing efficiency.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
