Description

Technical Field

[0001] This application relates to the field of steel pipe processing technology, and specifically discloses a stainless steel pipe surface polishing device. Background Technology

[0002] Stainless steel pipe is a long, round steel material, mainly used in industrial pipelines for conveying materials in petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components.

[0003] During the production process, stainless steel pipes may have uneven surface defects, burrs, oxides, or contaminants left due to welding, manufacturing, and other processes. These defects can easily affect the performance of the pipes and lead to corrosion and rust on the pipe surface. Currently, polishing equipment is used to polish the outer surface of stainless steel pipes. By using abrasives or grinding tools of different particle sizes, the outer surface of the pipe is mechanically ground and polished.

[0004] However, during the polishing process of stainless steel pipes, when burrs appear on the surface of the stainless steel pipe, the burrs are easily splashed at high speed into the surrounding environment due to the acute grinding impact of the polishing tools. If they splash onto the operator, they will threaten the operator's personal safety and pose a safety hazard. In addition, when the polishing tools grind the suddenly appearing burrs, they will also damage the polishing wheel. Therefore, in view of this, the inventor provides a stainless steel pipe surface polishing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that burrs on the surface of traditional stainless steel pipes are easily splashed at high speed towards the operator when subjected to acute grinding impact, posing a safety hazard and damaging the grinding wheel.

[0006] To achieve the above objectives, the basic solution of this utility model provides a stainless steel pipe surface polishing device, including a processing table, mounting seats symmetrically arranged at both ends of the processing table, clamping components on the mounting seats for clamping and fixing both ends of the stainless steel pipe, polishing components for polishing the outer surface of the stainless steel pipe, and a controller. The polishing components include a mounting frame on the processing table, a polishing wheel rotatably connected to the top of the mounting frame and capable of polishing the outer surface of the stainless steel pipe, and a first rotating module on the top of the mounting frame for driving the polishing wheel to rotate. The first rotating module is electrically connected to the controller. A chamfering plate is provided on the outer periphery of the polishing wheel, and the chamfering plate is inclined outward from the end of the polishing wheel near the stainless steel pipe toward the end of the polishing wheel away from the stainless steel pipe. A rotation component is provided on the mounting seat for driving the stainless steel pipe to rotate. A drive component is also provided on the processing table for driving the mounting frame to move linearly along the axial direction of the stainless steel pipe.

[0007] The principle and effect of this basic scheme are as follows: 1. Compared with the prior art, this utility model, by setting a grinding wheel, facilitates the polishing and grinding of the surface of the stainless steel pipe. By setting a rotating component, it facilitates the rotation of the stainless steel pipe, thereby enabling the grinding wheel to achieve axial linear and comprehensive contact and grinding of the side of the stainless steel pipe. By setting a chamfered disc that slopes outward from the end of the grinding wheel closest to the stainless steel pipe towards the end furthest from the stainless steel pipe, it facilitates gradual burr removal when the grinding wheel encounters protruding burrs while polishing along the stainless steel pipe, avoiding... This design prevents burrs from being thrown at high speed during sudden grinding, thus avoiding injury to the operator from the impact of the flying burrs and improving the safety of stainless steel pipe polishing. It also prevents damage to the grinding wheel due to sudden force. The drive component facilitates the position adjustment of the grinding wheel, and the rotation component facilitates the clamping and processing surface control of the stainless steel pipe. This solves the problem that traditional stainless steel pipe surface burrs are easily thrown at high speed towards the operator during acute grinding impacts, posing a safety hazard and damaging the grinding wheel.

[0008] Furthermore, the clamping assembly includes a clamping seat horizontally and vertically disposed on the inner end face of the mounting base, a first electric telescopic rod horizontally and vertically disposed at the end of the clamping seat away from the mounting base, and an electric gripper disposed at the end of the first electric telescopic rod for clamping the end of the stainless steel pipe. Both the first electric telescopic rod and the electric gripper are electrically connected to the controller. By setting the first electric telescopic rod to drive the electric gripper to extend and retract laterally, it is convenient to clamp and fix the end of the stainless steel pipe.

[0009] Furthermore, the electric gripper includes a fixed block located at the end of the first electric telescopic rod and extending into both ends of the stainless steel tube; a plurality of electric push rods evenly and symmetrically arranged on the side of the fixed block; a positioning plate located at the end of the electric push rod; an end face abutment plate vertically arranged on the side of the positioning plate near the clamping seat and used for lateral support of the end face of the stainless steel tube; a second electric telescopic rod located on the side surface of the positioning plate away from the fixed block; and a lateral limiting post located at the end of the second electric telescopic rod and used for outward support of the inner wall of the end of the stainless steel tube. The axial direction of the lateral limiting post is parallel to the axial direction of the stainless steel tube. Both the electric push rod and the second electric telescopic rod are electrically connected to the controller. By setting multiple electric push rods on the side of the fixing block to drive the positioning plate, end face abutment plate and lateral limiting post to extend and retract along the radial direction of the stainless steel pipe, it is convenient to clamp and fix stainless steel pipes of different diameters. The second electric telescopic rod drives the lateral limiting post to provide radial resistance support to the inner wall of the stainless steel pipe, and the end face abutment plate provides radial resistance limitation to the outer sides of both ends of the stainless steel pipe, thereby realizing the close clamping and fixed installation of the ends of the stainless steel pipe.

[0010] Furthermore, the self-rotating assembly includes a mounting box located between the clamping seat and the mounting base, and a second rotating module installed within the mounting box. The end of the first electric telescopic rod is coaxially and fixedly mounted with the end face of the second rotating module, and the second rotating module is electrically connected to the controller. By setting up the mounting box and the second rotating module, it is convenient to drive the rotation of the overall structure of the first electric telescopic rod and the electric gripper, thereby realizing the rotational control of the stainless steel pipe structure.

[0011] Furthermore, the drive assembly includes a linear drive module mounted between the mounting bases and located on the processing table, and a guide rod located on the side of the linear drive module for guiding and limiting the mounting frame. The linear drive module is electrically connected to the controller. By setting up the linear drive module, linear drive of the mounting frame and the grinding wheel is facilitated, thereby allowing the grinding wheel's workstation to cover the entire stainless steel pipe. By setting up the guide rod, the movement of the mounting frame and the grinding wheel is easily guided, ensuring the stability of the overall structure during operation.

[0012] Furthermore, the axis of the grinding wheel and the axis of the first electric telescopic rod are located on the same horizontal plane. By setting the height of the grinding wheel and the first electric telescopic rod to be the same, the center of the grinding wheel is at the same height as the stainless steel pipe, thereby making the grinding process of the grinding wheel more uniform and effective.

Figure 1 As shown: The system includes a processing table 1, mounting bases 2 symmetrically arranged at both ends of the processing table 1, clamping components mounted on the mounting bases 2 for clamping and fixing the two ends of a stainless steel tube, a polishing component for polishing the outer surface of the stainless steel tube, and a controller. The polishing component includes a mounting frame 4 located on the processing table 1, a polishing wheel 5 rotatably connected to the top of the mounting frame 4 and capable of polishing the outer surface of the stainless steel tube, and a first rotating module located on the top of the mounting frame 4 for driving the polishing wheel 5 to rotate. The first rotating module is electrically connected to the controller. A chamfering disc 7 is provided on the outer periphery of the polishing wheel 5. The chamfering disc 7 is inclined outward from the end of the polishing wheel 5 near the stainless steel tube towards the end of the polishing wheel 5 away from the stainless steel tube, wherein the inclination angle of the chamfering disc 7 does not exceed 40 degrees. A rotation component is provided on the mounting base 2 for driving the stainless steel tube to rotate. A drive component is also provided on the processing table 1 for driving the mounting frame 4 to move linearly along the axial direction of the stainless steel tube.

[0018] Among them, such as Figure 1 As shown, the clamping assembly includes a clamping seat 8 that is horizontally and vertically disposed on the inner end face of the mounting base 2, a first electric telescopic rod 9 that is horizontally and vertically disposed at the end of the clamping seat 8 away from the mounting base 2, and an electric gripper 10 disposed at the end of the first electric telescopic rod 9 and used to clamp the end of the stainless steel pipe. Both the first electric telescopic rod 9 and the electric gripper 10 are electrically connected to the controller.

[0019] Among them, such as Figure 1 As shown, the electric gripper 10 includes a fixing block 11 located at the end of the first electric telescopic rod 9 and extending into both ends of the stainless steel tube; four electric push rods 12 evenly and symmetrically arranged on the side of the fixing block 11; a positioning plate 13 located at the end of the electric push rod 12; an end face abutment plate 14 vertically arranged on the side of the positioning plate 13 near the clamping seat 8 and used for lateral support of the end face of the stainless steel tube; a second electric telescopic rod 15 located on the side surface of the positioning plate 13 away from the fixing block 11; and a lateral limiting post 16 located at the end of the second electric telescopic rod 15 and used for outward support of the inner wall of the end of the stainless steel tube. The axial direction of the lateral limiting post 16 is parallel to the axial direction of the stainless steel tube. Both the electric push rod 12 and the second electric telescopic rod 15 are electrically connected to the controller.

[0020] Among them, such as Figure 1 As shown, the self-rotating assembly includes a mounting box 17 located between the clamping seat 8 and the mounting seat 2, and a second rotating module installed inside the mounting box 17. The end of the first electric telescopic rod 9 is coaxially fixedly installed with the end face of the second rotating module, and the second rotating module is electrically connected to the controller.

[0021] Among them, such as Figure 1As shown, the drive assembly includes a linear drive module 6 mounted between the mounting bases 2 and located on the processing table 1, and a guide side rod 3 located on the side of the linear drive module 6 for guiding and limiting the mounting frame 4. The linear drive module 6 is electrically connected to the controller.

[0022] Among them, such as Figure 1 As shown, the axis of the grinding wheel 5 and the axis of the first electric telescopic rod 9 are located on the same horizontal plane.

[0023] In the specific implementation of this utility model, when it is necessary to polish the outer surface of the stainless steel pipe, the stainless steel pipe needs to be installed between the clamping components for suspension and fixation. During installation, the first electric telescopic rod 9 and the electric push rod 12 are first adjusted by the controller to retract to their shortest state. Then, the left end of the stainless steel pipe is placed over the electric gripper 10 on the left end of the processing table 1, so that the left end face of the stainless steel pipe is in contact with the right side face of the end face abutment plate 14. Next, the second electric telescopic rod 15 is extended by the controller, so that the lateral limiting post 16 is tangentially abutted against the inner wall of the stainless steel pipe, thus completing the limiting installation of the left end of the stainless steel pipe. At this time, the operator needs to manually lift the stainless steel pipe. The process begins with the first electric telescopic rod 9 extending under the control of the controller. The electric gripper 10 at the end of the first electric telescopic rod 9, located on the right side of the processing table 1, extends into the right end of the stainless steel tube, bringing the end face plate 14 of the electric gripper 10 against the right end face of the stainless steel tube. The controller then adjusts the extension of the second electric telescopic rod 15, making the lateral limiting post 16 of the right-side electric gripper 10 tangent to the inside of the stainless steel tube. If the distance between the end face plate 14 and the lateral limiting post 16 and the stainless steel tube is too large, the controller drives the electric push rod 12 to extend, adjusting the position of the positioning plate 13 closer to the stainless steel tube. Next, the polishing process begins. The controller first controls the rotation of the first and second rotating modules, driving the stainless steel tube and the polishing turntable to rotate. After the polishing turntable rotates, the outer surface of the stainless steel tube is polished. Then, the controller controls the linear drive module 6 to slowly move the mounting frame 4 along the axial direction of the stainless steel tube. When a raised burr appears on the surface of the stainless steel pipe, the chamfering disc 7 located on the outer ring of the grinding disc slowly contacts and grinds the raised burr at an angle until it is smooth.

[0024] Compared with the prior art, this utility model facilitates the polishing and grinding of the stainless steel pipe surface by setting a grinding wheel 5. The self-rotating component facilitates the rotation of the stainless steel pipe, allowing the grinding wheel 5 to achieve axial linear and comprehensive contact and grinding of the side of the stainless steel pipe. The chamfered disc 7, which slopes outward from the end of the grinding wheel 5 closest to the stainless steel pipe towards the end furthest from the stainless steel pipe, facilitates gradual deburring when the grinding wheel 5 encounters protruding burrs while polishing along the stainless steel pipe. To prevent burrs from being subjected to sudden grinding impacts and flying outwards at high speed, thus avoiding operator injury from contact with the high-speed flying burrs, the safety of stainless steel pipe polishing is improved. At the same time, it also avoids damage to the grinding wheel 5 due to sudden force. By setting a drive component, the position of the grinding wheel 5 can be easily adjusted. By setting a self-rotating component, the clamping and processing surface of the stainless steel pipe can be easily adjusted. This solves the problem that in traditional stainless steel pipes, burrs on the surface are easily thrown at high speed towards the operator when subjected to acute grinding impacts, posing a safety hazard and damaging the grinding wheel.
