Description

Technical Field

[0001] The present application relates to the technical field of metal polishing, and more specifically, to a device for polishing the inner wall surface of a metal pipe joint. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process on the surface of a workpiece using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss.

[0003] When using existing polishing devices for metal product processing, when polishing tubular metals, due to the different inner diameters of metal tubes, fixed polishing is usually achieved only by clamping the two ends or clamping the outer surface. The actual polishing efficiency of the curved surface of the tubular metal is low, the polishing area is small, and fast and effective polishing cannot be achieved.

[0004] For example, a polishing device for metal product processing disclosed in Chinese patent CN214869645U is provided, by adding a motor to the back of a vertical plate, connecting and installing a sleeve plate with a rotating shaft connected to the end of the motor output shaft, by movably clamping a clamping rod on the inner surface of the sleeve plate, and adding a fixing plate on the top surface of the clamping rod to movably clamp the top groove of the sleeve plate, and adding a side plate on the top surface of the sleeve plate to sleeve a threaded rod, and the threaded rod is sleeved with the fixing plate thread, and the position of the clamping rods on both sides is changed by rotating the threaded rods with opposite threads on both sides, so as to adapt to the inner diameters of different metal pipes and realize the clamping and fixing of metal pipes of different specifications, and the clamped metal pipe is driven to rotate by the motor to realize polishing with the nearby polishing plate, thereby ensuring the polishing area, improving the polishing effect, and improving the polishing efficiency.

[0005] However, when polishing the inner wall of the metal pipe, when fixing metal pipes of different sizes, metal pipes of different sizes require polishing heads of different sizes, and polishing heads of different specifications need to be replaced, which requires disassembly and then installation, which is a complicated process and reduces work efficiency.

[0032] The polishing assembly includes a fixed frame 1, a plurality of fixed boxes 4, a handle 5, a first bevel gear 6, a second bevel gear 7, a threaded rod 8, a connecting block 9, a polishing head 10 and a multi-station assembly. Each fixed box 4 is arranged on one side of the fixed frame 1, each handle 5 is arranged on one side of the corresponding fixed box 4, one side of each handle 5 passes through the corresponding fixed box 4 through a rotating shaft, each handle 5 is fixedly connected to the first bevel gear 6 through the rotating shaft, each fixed box 4 is rotatably connected to the corresponding rotating shaft, each threaded rod 8 is arranged inside the corresponding fixed box 4 and rotatably connected to the inner wall of the corresponding fixed box 4, Each second bevel gear 7 is fixedly connected to one end of the corresponding threaded rod 8 close to the first bevel gear 6, each second bevel gear 7 is meshed with the corresponding first bevel gear 6, each connecting block 9 is threadedly connected to the outer wall of the threaded rod 8, and a second slide groove 19 is opened on one side of each fixed box 4, and each second slide groove 19 is respectively slidably connected to the corresponding connecting block 9, and each connecting block 9 is fixedly connected with a polishing head 10 after passing through the corresponding second slide groove 19. When replacing the polishing head 10 during polishing, it is only necessary to turn the handle 5. The rotation of the handle 5 drives the first bevel gear 6 to rotate through the rotating shaft, and the second bevel gear 10 is rotated. A bevel gear 6 drives two second bevel gears 7 to rotate in the opposite direction. Since the two threaded rods 8 have the same thread direction, when the two second bevel gears 7 rotate in the opposite direction, the two connecting blocks 9 will be driven to slide in the opposite direction. The two connecting blocks 9 slide in the opposite direction to adjust the distance of the two polishing heads 10. Since the polishing heads 10 are all set to a semicircular shape, they can fit the inner walls of different metal pipe joints more closely. After adjusting to the corresponding size, the movable plate 2 is moved to the corresponding polishing position by the second electric push rod 18, and then the driving motor 11 is started. The output end of the driving motor 11 rotates to drive the driving gear 12 to rotate. The driving gear 12 rotates to drive multiple driven gears 13 to rotate. The multiple driven gears 13 rotate and drive multiple fixed boxes 4 to rotate through the rotating shaft. The rotation of the multiple fixed boxes 4 drives the multiple polishing heads 10 to rotate and polish. Through the setting of the adjustment of the polishing head 10 in the polishing device, polishing heads 10 of different sizes can adapt to the inner walls of metal pipes of different types and sizes, and the polishing speed can be accelerated. By adjusting the size of the polishing head 10, a more flexible, efficient and accurate polishing solution can be provided according to the specific situation, thereby meeting the needs of polishing of different surfaces.

[0033] Reference Figure 1-Figure 4The multi-station assembly is arranged on a side away from the fixed box 4. The multi-station assembly includes a driving motor 11. The output end of the driving motor 11 is fixedly connected with a driving gear 12. Each fixed box 4 is fixedly connected with a driven gear 13 after passing through the fixed frame 1 through a rotating shaft away from the polishing head 10. Each rotating shaft passes through the fixed frame 1 and is fixedly connected with the corresponding fixed box 4. Each driven gear 13 is meshed with the driving gear 12. By starting the driving motor 11, the rotation of the output end of the driving motor 11 will drive the driving gear 12 to rotate. The rotation of the driving gear 12 will drive multiple driven gears 13 to rotate. The rotation of multiple driven gears 13 drives multiple fixed boxes 4 to rotate through the rotating shaft. The rotation of multiple fixed boxes 4 drives multiple polishing heads 10 to rotate and polish. By processing multiple workpieces at the same time, multi-station polishing can significantly shorten the polishing cycle, save time and labor costs, and multi-station polishing can process multiple workpieces at the same time in the same working area. Therefore, compared with single-station polishing, it requires less space and can more effectively utilize the production site. Through multi-station polishing, multiple workpieces can be processed at the same time, thereby greatly improving the production efficiency of the polishing process.

[0034] Reference Figure 1-Figure 2 The fixed assembly includes a movable frame 2, a plurality of fixed plates 14, a clamping plate 15, a first electric push rod 16 and a first slide groove 17. Each fixed box 4 is arranged corresponding to the corresponding fixed plate 14. Each fixed plate 14 is arranged on a side close to the fixed frame 1. Each first electric push rod 16 is provided with a plurality of groups, and the number of each group of first electric push rods 16 is set to two. Each clamping plate 15 is fixed to the output end of the corresponding first electric push rod 16. The first slide groove 17 is opened at the top of the base 3. Each first slide groove 17 is slidably connected to the bottom of the movable frame 2. A second electric push rod 18 is provided on the side of the movable frame 2 away from the fixed frame 1. The output end of the second electric push rod 18 is fixedly connected to the movable frame 2. The metal pipe joints of different sizes are fixed by the corresponding two first electric push rods 16, and then the corresponding polishing position of the movable plate 2 is polished by the second electric push rod 18, so as to improve the overall polishing efficiency.

[0035] Working principle: Turn the handle 5, and the handle 5 rotates to drive the first bevel gear 6 to rotate through the rotating shaft, and the first bevel gear 6 drives the two second bevel gears 7 to rotate in the opposite direction. Since the two threaded rods 8 have the same thread direction, when the two second bevel gears 7 rotate in the opposite direction, the two connecting blocks 9 will be driven to slide in the opposite direction. The opposite sliding of the two connecting blocks 9 will adjust the two polishing heads 10 to adjust the distance. Since the polishing heads 10 are all set to a semicircular shape, they can fit the inner walls of different metal pipe joints more closely. After adjusting to the corresponding size, the movable plate 2 is moved to the corresponding polishing position through the second electric push rod 18, and then by starting the drive motor 11, the rotation of the output end of the drive motor 11 will drive the driving gear 12 to rotate, and the rotation of the driving gear 12 will drive multiple driven gears 13 to rotate, and the rotation of multiple driven gears 13 drives multiple fixed boxes 4 to rotate through the rotating shaft, and the rotation of multiple fixed boxes 4 drives multiple polishing heads 10 to rotate and polish.
