Stainless steel pipes are classified by material into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes, coated and coated pipes, etc. for saving precious metals and meeting special requirements. In the production of stainless steel pipes, there are seamless pipes and welded pipes. When stainless steel pipes are produced by welding, there will be weld seams on the inner side of the stainless steel pipes. The weld seams not only make the stainless steel pipes unsightly but also affect the use of the stainless steel pipes.

[0019] A method for using an inner wall leveling device for stainless steel welded steel pipes specifically includes the following steps:

[0020] S1: During use, insert the steel pipe to be processed outside the fixing member. Then, control the rotation of the mounting shaft by rotating the second servo motor. The rotation of the mounting shaft can drive the rotation of the worm. The rotation of the worm can drive the rotation of the worm gear. The rotation of the worm gear can drive the rotation of the second threaded rod. The slide rod functions to limit the position of the support member. When the second threaded rod rotates, the position of the support member can be adjusted to move the support member outward from the fixing member. The inner wall of the steel pipe is supported by the movement of the support member. The steel pipe rotates outside the support member through the contact roller. Then, drive the rotation shaft to move inside the adjustment groove by the second electric push rod, so as to adjust the distance between the support cylinder on the side wall of the rotation shaft and the fixing member, thereby cooperating with the support member to clamp steel pipes of different wall thickness specifications. The second spring enables the support cylinder to have a certain amount of movement space and clamping force, so that the anti-slip member on the side wall of the support cylinder is in close contact with the side wall of the steel pipe. The third servo motor can be used to control the rotation of one of the transmission wheels. When one of the transmission wheels rotates through the transmission belt, it can drive the other transmission wheel to rotate simultaneously. The rotation of the transmission wheel can be used to control the rotation of the rotation shaft, thereby driving the rotation of the steel pipe.

[0021] S2: Drive the rotation of the first threaded rod by running the first servo motor. The rotation of the first threaded rod can cause the first slider to slide inside the chute, thereby adjusting the movement of the movable plate on the top of the base until the mounting member moves inside the steel pipe and the moving member is located on the inner wall of the steel pipe weld.

[0022] S3: Control the movement of the moving part through the first electric push rod, so that the processing part on the side wall of the moving part is in contact with the position on the inner wall of the steel pipe weld that needs to be processed, and process the inner wall of the steel pipe weld. During the processing, the liquid in the liquid storage tank is pumped by the transfer pump, and the transfer pump transports the liquid to the inside of the corrugated expansion pipe through the communication groove, and then the liquid is transported to the nozzle by the corrugated expansion pipe and sprayed out. After the moving part moves through the corrugated expansion pipe, the communication between the communication groove and the nozzle is ensured, and the stability of the liquid transportation is ensured. When the liquid for grinding and polishing is sprayed out by the nozzle to process the inner wall of the steel pipe, the effect is better.

[0023] The present invention has at least the following beneficial effects:

[0024] (1) In this solution, by setting the adjusting clamping mechanism, the rotation of the worm can drive the rotation of the worm wheel, and the rotation of the worm wheel can drive the rotation of the second threaded rod. By setting the slide rod, the effect of limiting the support part is achieved. When the second threaded rod rotates, the position of the support part can be adjusted, so that the support part moves outward from the fixed part. By the movement of the support part, the inner wall of the steel pipe can be supported. By setting the second electric push rod, the rotating shaft can be driven to move inside the adjustment groove, so that the distance between the support cylinder on the side wall of the rotating shaft and the fixed part can be adjusted, so as to cooperate with the support part to clamp steel pipes with different wall thickness specifications. By adjusting the positions of the support part and the rotating shaft, the effect of clamping steel pipes with various wall thickness specifications can be achieved, and the use is more flexible and convenient, making the use effect of the stainless steel welded steel pipe weld inner flattening equipment better;

[0025] (2) In this solution, by setting the transmission tensioning mechanism, the third servo motor can be used to control the rotation of one of the transmission wheels. When one of the transmission wheels rotates through the transmission belt, the other transmission wheel can be driven to rotate at the same time. By the rotation of the transmission wheel, the rotation of the rotating shaft can be controlled. When the rotating shaft moves under the control of the second electric push rod, the transmission wheel moves together. At this time, the transmission belt will be in a loose state and cannot ensure the transmission between the transmission wheels. By setting the third spring, it can be used to support the connecting rod, so that the roller inside the chuck can be pressed against the surface of the transmission belt, so that the transmission belt can ensure the transmission effect even after the transmission wheel moves. By setting the roller, the friction between the chuck and the transmission belt can be reduced. By setting the adjusting screw rod, the position of the sliding plate inside the fixed frame can be adjusted, so that the compression degree of the third spring can be adjusted, and thus the tensioning force of the chuck on the transmission belt can be adjusted;

[0026] (3) This solution sets up an adjustment and processing mechanism, and can extract the liquid inside the liquid storage tank through the delivery pump. By setting up a connecting groove, the delivery pump can deliver the liquid to the inside of the bellows through the connecting groove, and then the bellows can deliver the liquid to the nozzle for spraying. By setting up the bellows, the connection between the connecting groove and the nozzle can still be ensured after the moving part moves, thereby ensuring the stability of liquid delivery. By setting up the nozzle to spray the polishing liquid, the effect can be better when the inner wall of the steel pipe is polished.

[0027] (4) This solution sets up a moving mechanism. By setting up a first servo motor, it can be used to drive the first threaded rod to rotate. The rotation of the first threaded rod can make the first slider slide inside the slide groove, so that the movable plate can be adjusted to move on the top of the base. By setting up a second slider and a slide rail, the stability of the movable plate movement can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

By providing the liquid storage tank 217, it can be used to store the liquid for grinding and polishing. By providing the filling pipe 218, it can be used to fill the liquid into the liquid storage tank 217. By providing the connecting pipe 216, the liquid storage tank 217 can be connected to the delivery pump 215, so that the delivery pump 215 can extract the liquid inside the liquid storage tank 217. By providing the communication groove 214, the delivery pump 215 can deliver the liquid into the corrugated expansion pipe 213 through the communication groove 214, and then the liquid is delivered to the spray head 212 by the corrugated expansion pipe 213 and sprayed out. By providing the corrugated expansion pipe 213, the communication between the communication groove 214 and the spray head 212 can still be ensured after the movable member 211 moves, ensuring the stability of liquid delivery.

By providing the first electric push rod 219, the movement of the movable member 211 can be controlled, so that the processing member 221 on the side wall of the movable member 211 can contact the position on the inner wall of the steel pipe weld that needs to be processed, and the inner wall of the steel pipe weld can be processed.

[0055] Workflow and principle of the present invention: When in use, insert the steel pipe to be processed outside the fixing member 31. Then, rotate the mounting shaft 312 by controlling the rotation of the second servo motor 311. The rotation of the mounting shaft 312 can drive the rotation of the worm 313. The rotation of the worm 313 can drive the rotation of the worm gear 314. The rotation of the worm gear 314 can drive the rotation of the second threaded rod 315. By setting the slide bar 317, the effect of limiting the support member 32 is achieved. When the second threaded rod 315 rotates, the position of the support member 32 can be adjusted to move the support member 32 outward from the fixing member 31. The inner wall of the steel pipe is supported by the movement of the support member 32. The steel pipe rotates outside the support member 32 through the contact roller 321. Then, drive the rotation shaft 34 to move inside the adjustment groove 33 by the second electric push rod 332, so as to adjust the distance between the support cylinder 342 on the side wall of the rotation shaft 34 and the fixing member 31, so as to cooperate with the support member 32 to clamp steel pipes with different wall thickness specifications. The second spring 341 enables the support cylinder 342 to have a certain movement space and clamping force, so that the anti-slip member 343 on the side wall of the support cylinder 342 is in close contact with the side wall of the steel pipe. The third servo motor 354 can be used to control the rotation of one of the transmission wheels 355. When one of the transmission wheels 355 rotates through the transmission belt 356, it can drive the other transmission wheel 355 to rotate simultaneously. The rotation of the transmission wheel 355 can realize the control of the rotation of the rotation shaft 34, so as to drive the steel pipe to rotate. When the rotation shaft 34 moves under the control of the second electric push rod 332, the transmission wheel 355 moves together. At this time, the transmission belt 356 will be in a loose state, and the transmission between the transmission wheels 355 cannot be guaranteed. By setting the third spring 363, it can be used to support the connecting rod 364, so that the roller 366 inside the chuck 365 can be closely attached to the surface of the transmission belt 356, so that the transmission belt 356 can ensure the transmission effect even after the transmission wheel 355 moves. By setting the roller 366, the friction between the chuck 365 and the transmission belt 356 can be reduced. By setting the adjusting screw 361, the position of the sliding plate 362 inside the fixed frame 36 can be adjusted, so as to adjust the compression degree of the third spring 363, so as to adjust the tensioning force of the chuck 365 on the transmission belt 356 and ensure the rotation effect of the rotation shaft 34. Then, drive the rotation of the first threaded rod 102 by the operation of the first servo motor 104. The rotation of the first threaded rod 102 can make the first slider 202 slide inside the chute 101, so as to adjust the movement of the movable plate 2 on the top of the base 1 until the mounting member 21 moves inside the steel pipe, so that the moving member 211 is located on the inner wall of the steel pipe weld. Then, control the movement of the moving member 211 by the first electric push rod 219, so that the processing member 221 on the side wall of the moving member 211 is in contact with the position to be processed on the inner wall of the steel pipe weld, and process the inner wall of the steel pipe weld. During the processing, pump the liquid inside the liquid storage tank 217 by the delivery pump 215, and the delivery pump 215 transports the liquid into the corrugated expansion pipe 213 through the communication groove 214 through the communication groove 214.It is then conveyed to the nozzle 212 by the corrugated expansion pipe 213 and sprayed out. By moving the moving part 211 through the corrugated expansion pipe 213, the connection between the communication groove 214 and the nozzle 212 is ensured, and the stability of liquid transportation is ensured. When the liquid for grinding and polishing is sprayed out through the nozzle 212 to grind the inner wall of the steel pipe, the effect is better.
