Description
Technical Field
[0001] This utility model relates to the field of processing device technology, specifically to an automated surface treatment device for welded pipes. Background Technology
[0002] Welded pipe, also known as welded steel pipe, is a type of steel pipe made by rolling steel plates or strips into shape and then welding them together. Its production process is simple, efficient, and diverse in specifications, requiring less equipment investment. However, its strength is generally lower than that of seamless steel pipe. Welded pipe can be divided into straight seam welded pipe and spiral welded pipe according to the welding method. After welding, weld marks are left on the surface of the welded pipe. In order to ensure the smoothness of the surface of the welded pipe, the weld marks need to be ground off. Traditional grinding methods are mostly manual, which has low grinding efficiency. To improve this situation, an automated surface treatment device for welded pipe is proposed.
[0003] For example, the automated surface polishing device for stainless steel pipes disclosed in the authorization announcement number CN217019909U includes a support platform, a conveying chamber fixedly installed above the support platform, a top plate fixedly installed on the top of the conveying chamber, and polishing equipment provided on the right side of the conveying chamber.
[0004] Although it realizes the automated surface polishing device for stainless steel pipes, through the combined use of the top plate, the limiting base, and the limiting column, after the steel pipe is inserted into the conveying chamber, the operator can rotate the adjusting bolt, and through the bearing at the bottom of the adjusting bolt, drive the limiting base to slide, thereby causing the limiting column to move closer to the conveying roller until the outer surface of the limiting column contacts the steel pipe. In conjunction with the conveying roller, the steel pipe is clamped and fixed. At the same time, the steel pipe can also be conveyed into the polishing equipment through the combined action of the conveying roller and the limiting column, ensuring the normal progress of the polishing work.
[0005] However, this does not solve the problem that the existing processing device is not conducive to convenient and uniform grinding of the outer wall of steel pipes, nor is it easy to adjust and adapt to steel pipes of different lengths, which affects the grinding effect and the flexibility of use. Utility Model Content
[0006] The purpose of this utility model is to provide an automated surface treatment device for welded pipes, so as to solve the problems mentioned in the background art, which are not convenient and easy to uniformly grind the outer wall of steel pipes, are not conducive to adjusting and adapting to steel pipes of different lengths, and affect the grinding effect and the flexibility of use.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated surface treatment device for welded pipes, comprising a worktable and an integrated frame. The integrated frame is symmetrically mounted on the top of the worktable. Each integrated frame has a lead screw installed inside, and the lead screw is movably connected to the integrated frame. A servo motor is installed on the side wall of each integrated frame, and the output end of the servo motor is connected to the lead screw. A threaded sleeve is fitted onto the surface of each lead screw, and the threaded sleeve is threadedly connected to the lead screw and slidably connected to the integrated frame. A grinding mechanism is installed at the top of each threaded sleeve. Two sets of support frames are installed inside the worktable, with one set of support frames fixedly connected to the worktable and the other set slidably connected to the worktable.
[0008] Preferably, racks are symmetrically installed on the inner wall of the workbench, and drive motors are symmetrically installed at the bottom end of the sliding support frame.
[0009] Preferably, each of the drive motors has a drive shaft installed at its output end, and each drive shaft has a drive gear fitted on its surface, with the drive gear meshing with the rack.
[0010] Preferably, each of the supporting frames has a movable ring inside, and the movable ring is movably connected to the supporting frame.
[0011] Preferably, an adjustment motor is installed on the side wall of each of the supporting frames, and a hinge shaft is installed at the output end of each adjustment motor.
[0012] Preferably, the surfaces of the hinge shafts are fitted with transmission gears, and the transmission gears mesh with the movable ring.
[0013] Preferably, four sets of L-shaped frames with equal spacing are installed on the side wall of the movable ring, and sliders are slidably installed on the surface of each L-shaped frame, and clamping blocks are installed on the side wall of each slider.
[0014] Preferably, hydraulic rods are installed on the side walls of the L-shaped frame, and the output end of the hydraulic rods is connected to the clamping block.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the processing device not only realizes convenient and uniform grinding of the outer wall of steel pipe and facilitates adjustment and adaptation to process steel pipes of different lengths, but also improves the grinding effect and the flexibility of use.
[0016] (1) The welded steel pipe is placed inside the two sets of movable rings. The hydraulic rod drives the clamping block to move on the surface of the L-shaped frame so that multiple sets of clamping blocks move synchronously to the center position of the movable ring. Under the cooperation of multiple sets of clamping blocks, the steel pipe is clamped and fixed. Then, the grinding mechanism is opened so that the grinding mechanism is close to the outer wall of the steel pipe. The grinding mechanism grinds the outer wall of the steel pipe. The adjusting motor drives the transmission gear to rotate through the hinge shaft. The transmission gear drives the movable ring to rotate inside the bearing frame. The movable ring drives the steel pipe to rotate so that the grinding mechanism grinds the outer wall of the steel pipe evenly. The servo motor drives the lead screw to rotate. The lead screw drives the threaded sleeve to move. The threaded sleeve drives the grinding mechanism to move. The grinding mechanism moves and adjusts the grinding of different positions of the steel pipe, thereby improving the grinding effect of the outer wall of the steel pipe. It realizes convenient and uniform grinding of the outer wall of the steel pipe and improves the grinding effect.
[0017] (2) When the steel pipe to be ground is long, the drive motor drives the drive gear to rotate through the drive shaft, while the rack remains stationary. The drive gear drives the support frame to move inside the worktable, thereby adjusting the distance between the two sets of support frames to accommodate steel pipes of different lengths and thus improving the flexibility of the device.

Each integrated frame 2 is provided with a servo motor 9 on its side wall, which serves as a power drive. The output end of the servo motor 9 is connected to the lead screw 10. Each lead screw 10 is fitted with a threaded sleeve 11, which is threadedly connected to the lead screw 10 and slidably connected to the integrated frame 2. Each threaded sleeve 11 is provided with a grinding mechanism 3 at its top. Two sets of bearing frames 4 are provided inside the workbench 1. One set of bearing frames 4 is fixedly connected to the workbench 1, and the other set of bearing frames 4 is slidably connected to the workbench 1.
[0026] First, the welded steel pipe is placed inside the two sets of movable rings 15. The hydraulic rod 17 is opened, and with the sliding engagement of the slider 19 and the L-shaped frame 16, the hydraulic rod 17 drives the clamping blocks 18 to move on the surface of the L-shaped frame 16. This causes multiple sets of clamping blocks 18 to move synchronously towards the center of the movable rings 15, clamping and fixing the steel pipe in place. Then, the grinding mechanism 3 is opened, pressing it against the outer wall of the steel pipe. The grinding mechanism 3 then grinds the outer wall of the steel pipe. Simultaneously, the adjusting motor 12 is opened, driving the transmission gear 14 to rotate via the hinge shaft 13. The transmission gear 14 interacts with the movable rings 15... Under mutual meshing, the transmission gear 14 drives the movable ring 15 to rotate inside the bearing frame 4, and the movable ring 15 drives the steel pipe to rotate, so that the grinding mechanism 3 can uniformly grind the outer wall of the steel pipe. Then, the servo motor 9 is turned on, and the servo motor 9 drives the lead screw 10 to rotate. With the threaded connection between the lead screw 10 and the threaded sleeve 11, and the sliding cooperation between the threaded sleeve 11 and the integrated frame 2, the lead screw 10 drives the threaded sleeve 11 to move, and the threaded sleeve 11 drives the grinding mechanism 3 to move. The grinding mechanism 3 moves and adjusts the grinding of different positions of the steel pipe, thereby improving the grinding effect on the outer wall of the steel pipe, realizing convenient and uniform grinding of the outer wall of the steel pipe, and improving the grinding effect.
[0027] A rack 8 is symmetrically installed on the inner wall of the workbench 1, and a drive motor 5 is symmetrically installed at the bottom of the sliding support frame 4. The drive motor 5 plays the role of power drive.
[0028] Each output end of the drive motor 5 is equipped with a drive shaft 7, and each drive shaft 7 is fitted with a drive gear 6, which meshes with the rack 8.
[0029] The interior of the support frame 4 is provided with a movable ring 15, and the movable ring 15 is movably connected to the support frame 4. An adjustment motor 12 is installed on the side wall of the support frame 4. The adjustment motor 12 plays the role of power drive. The output end of the adjustment motor 12 is equipped with a hinge shaft 13.
[0030] The surface of the hinge shaft 13 is fitted with transmission gears 14, and the transmission gears 14 mesh with the movable ring 15. The side wall of the movable ring 15 is fitted with four sets of L-shaped frames 16 at equal intervals. The surface of the L-shaped frame 16 is slidably fitted with sliders 19, and the side wall of the sliders 19 is fitted with clamping blocks 18.
[0031] Hydraulic rods 17 are installed on the side walls of the L-shaped frame 16. The hydraulic rods 17 serve as power drives, and the output end of the hydraulic rods 17 is connected to the clamping block 18.
[0032] If the steel pipe to be ground is long, turn on the drive motor 5. The drive motor 5 drives the drive gear 6 to rotate through the drive shaft 7. With the meshing of the drive gear 6 and the rack 8, and the sliding engagement between the support frame 4 and the worktable 1, the rack 8 remains stationary. The drive gear 6 drives the support frame 4 to move inside the worktable 1, thereby adjusting the distance between the two sets of support frames 4 to accommodate steel pipes of different lengths, thus improving the flexibility of the device.
[0033] Working principle: First, the welded steel pipe is placed inside the two sets of movable rings 15. The hydraulic rod 17 drives the clamping blocks 18 to move on the surface of the L-shaped frame 16, so that multiple sets of clamping blocks 18 move synchronously towards the center position of the movable rings 15. Under the cooperative action of multiple sets of clamping blocks 18, the steel pipe is clamped and fixed. Then, the grinding mechanism 3 is opened, so that the grinding mechanism 3 is close to the outer wall of the steel pipe. The grinding mechanism 3 grinds the outer wall of the steel pipe. The adjusting motor 12 drives the transmission gear 14 to rotate through the hinge shaft 13. The transmission gear 14 drives the movable rings 15 to rotate inside the bearing frame 4. The movable rings 15 drive the steel pipe to rotate, so that the grinding mechanism 3 grinds the outer wall of the steel pipe evenly. The servo motor... 9 drives the lead screw 10 to rotate, which in turn drives the threaded sleeve 11 to move. The threaded sleeve 11 then drives the grinding mechanism 3 to move. The grinding mechanism 3 moves and adjusts the grinding of different positions on the steel pipe, thereby improving the grinding effect on the outer wall of the steel pipe. If the length of the steel pipe to be ground is long, the drive motor 5 drives the drive gear 6 to rotate through the drive shaft 7. Under the mutual meshing of the drive gear 6 and the rack 8, and the sliding cooperation between the bearing frame 4 and the worktable 1, the rack 8 remains stationary, and the drive gear 6 drives the bearing frame 4 to move inside the worktable 1, thereby adjusting the distance between the two sets of bearing frames 4 to adapt to steel pipes of different lengths. The above is the complete usage of the automated surface treatment device for welded pipes.
