Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe pole frame welding technology, specifically a steel pipe pole frame welding device. Background Technology
[0002] In modern industrial production, steel pipe pole frames are widely used in many fields such as power transmission and communication base stations. The welding quality of steel pipe pole frames directly affects their performance and safety, so high requirements are placed on the welding equipment. Before welding steel pipe pole frames, it is usually necessary to prepare and pre-treat the two steel pipes for welding.
[0003] According to announcement number CN 217096255 U, a welding device for processing steel pipe poles includes a welding device body. Both sides of the top of the welding device body are connected to arc-shaped plates. A clamping plate is rotatably connected to one side of the top of the arc-shaped plates. A first clamping plate is connected to one side of the outer wall of the clamping plate. Eight inserts are connected to the bottom of the first clamping plate. A fan blade is connected to the middle of the top of the welding device body. A chain is rotatably connected to the bottom of the inside of the fan blade. Three gears are meshed in the middle of the chain. Three fan blades are provided at the top of the chain.
[0004] This device enhances the safety of steel pipe poles and facilitates their disassembly and fixing. It also saves time when welding multiple steel pipe poles, reducing the possibility of dangerous situations. Furthermore, it utilizes a single motor to drive multiple fan blades to cool the welded areas of the steel pipe poles, reducing power consumption by cooling multiple angles. However, once the steel pipe is fixed, it cannot rotate, thus limiting welding to a single point and resulting in low welding efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe pole frame welding device, including a base, a support leg fixedly connected to the bottom of the base, a clamping and rotating mechanism provided at the top of the base, a fixing plate fixedly connected symmetrically to the left and right sides of the top of the base, an I-shaped plate fixedly connected to the top of the fixing plate, and a welding mechanism provided at the top of the I-shaped plate.
[0007] The clamping and rotating mechanism includes a fixed base, which is fixedly connected to the top of the base. Bidirectional lead screws are rotatably connected to the left and right sides of the fixed base. A first servo motor is fixedly connected to the right side of the fixed base. Limiting rods are symmetrically fixedly connected to the left and right sides of the fixed base. Moving seats are symmetrically threaded onto the surface of the bidirectional lead screws. A fixed frame is fixedly connected to the top of the moving seat. A cylinder is fixedly connected to the top of the fixed frame. A first clamping block is fixedly connected to the output end of the cylinder. A fixed block is fixedly connected to the top of the moving seat.

A first L-shaped seat is fixedly connected to the right side of the fixed block near the right side of the bottom of the base. A second servo motor is fixedly connected to the right side of the first L-shaped seat. A three-jaw chuck is fixedly connected to the output end of the second servo motor.
[0008] Preferably, the output end of the first servo motor is fixedly connected to the right end of the bidirectional lead screw. The left side of the movable seat has holes that match the limiting rod, and the movable seat is slidably connected to the surface of the limiting rod through the holes. The limiting rod limits the two movable seats symmetrically located on the surface of the bidirectional lead screw, so that the two movable seats move towards each other as the bidirectional lead screw rotates.
[0009] Preferably, the first clamping block is located above the first clamping block, and the left side of the fixing plate has a groove to facilitate the insertion of the steel pipe between the first clamping block and the second clamping block.
[0010] Preferably, the three-jaw chuck and the second clamping block are on the same horizontal line, so that the steel pipe can be clamped by the three-jaw chuck while being clamped by the first clamping block and the second clamping block.

[0012] Preferably, the gear meshes with a cylindrical rack.
[0013] Preferably, the top of the I-beam plate has a hole that matches the cylindrical rack, and the cylindrical rack is slidably connected to the hole by passing through its surface.
[0014] Compared with the prior art, the present invention provides a steel pipe pole frame welding device, which has the following beneficial effects:
[0015] 1. This steel pipe pole frame welding device uses a cylinder to move the first clamping block downwards, which cooperates with the second clamping block to achieve a stable clamping of the steel pipe. Simultaneously, the rollers on the inner sides of the first and second clamping blocks prevent damage to the surface of the steel pipe during clamping and allow the steel pipe to rotate flexibly when the three-jaw chuck is driven by the second servo motor. This facilitates circumferential welding of the steel pipe, reduces the complexity of manual operation, and improves welding efficiency.
[0016] 2. In this steel pipe pole frame welding device, the welding mechanism is driven by a third servo motor to rotate a gear. Because the gear meshes with a cylindrical rack, the rack slides up and down within a sliding sleeve, thereby moving the welding torch body up and down. This design allows for flexible adjustment of the welding torch body's height according to the pipe diameter and welding position requirements, ensuring the torch is accurately aligned with the welding area and improving welding precision.

[0025] This utility model provides the following technical solution:
[0026] Example 1
[0027] Please see Figure 1-3 This utility model provides a technical solution: a steel pipe pole frame welding device, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a clamping and rotating mechanism 3 provided on the top of the base 1, a fixing plate 4 fixedly connected to the left and right sides of the top of the base 1, an I-shaped plate 5 fixedly connected to the top of the fixing plate 4, and a welding mechanism 6 provided on the top of the I-shaped plate 5.
[0028] The clamping and rotating mechanism 3 includes a fixed base 31, which is fixedly connected to the top of the base 1. A bidirectional lead screw 32 is rotatably connected to the left and right sides inside the fixed base 31. A first servo motor 33 is fixedly connected to the right side of the fixed base 31. Limiting rods 34 are symmetrically fixedly connected to the left and right sides inside the fixed base 31. A movable base 35 is symmetrically threaded to the surface of the bidirectional lead screw 32. A fixed frame 36 is fixedly connected to the top of the movable base 35. A cylinder 37 is fixedly connected to the top of the fixed frame 36. A first clamping block 38 is fixedly connected to the output end of the cylinder 37. A fixed block 39 is fixedly connected to the top of the movable base 35. A second clamping block 311 is fixedly connected to the top of the fixed block 39. Rollers 312 are fixedly connected to the inner sides of both the first clamping block 38 and the second clamping block 311. A first L-shaped seat 313 is fixedly connected to the right side of the fixed block 39 near the bottom of the base 1. A second servo motor 314 is fixedly connected to the right side of the first L-shaped seat 313. A three-jaw chuck 315 is fixedly connected to the output end of the second servo motor 314.
[0029] The output end of the first servo motor 33 is fixedly connected to the right end of the bidirectional lead screw 32. The left side of the movable seat 35 has holes that match the limiting rod 34. The movable seat 35 is slidably connected to the surface of the limiting rod 34 through the holes. The limiting rod 34 limits the two movable seats 35 symmetrically on the surface of the bidirectional lead screw 32, so that the two movable seats 35 move towards each other as the bidirectional lead screw 32 rotates.
[0030] The first clamping block 38 is located above the first clamping block 38, and the left side of the fixing plate 4 has a groove to facilitate the insertion of the steel pipe between the first clamping block 38 and the second clamping block 311.
[0031] The three-jaw chuck 315 and the second clamping block 311 are on the same horizontal line, so that the steel pipe may be clamped by the three-jaw chuck 315 while being clamped by the first clamping block 38 and the second clamping block 311.
[0032] Example 2
[0033] Please see Figure 4 Furthermore, based on Example 1, welding mechanism 6 was obtained.
[0034] The welding mechanism 6 includes a second L-shaped base 61, which is fixedly connected to the top of the I-shaped plate 5 near the front. A third servo motor 62 is fixedly connected to the right side of the L-shaped base. A gear 63 is fixedly connected to the surface of the output shaft of the third servo motor 62. A sliding sleeve 64 is fixedly connected to the top of the I-shaped plate 5. A cylindrical rack 65 is slidably connected to the inner wall of the sliding sleeve 64. A welding torch body 66 is fixedly connected to the bottom end of the cylindrical rack 65.
[0035] Gear 63 meshes with cylindrical rack 65.
[0036] The top of the I-beam plate 5 has a hole that matches the cylindrical rack 65, and the cylindrical rack 65 is slidably connected to the hole by passing through the surface of the rack.
[0037] In actual operation, when this device is used, the first servo motor 33 is started according to the diameter and length of the steel pipe to be welded, and its output end drives the bidirectional lead screw 32 to rotate. Since the moving seat 35 has holes on the left side front and back that match the limiting rod 34, and is slidably connected to the surface of the limiting rod 34 through these holes, under the limiting action of the limiting rod 34, the two moving seats 35 connected by symmetrical threads on the surface of the bidirectional lead screw 32 will move towards each other as the bidirectional lead screw 32 rotates, thereby adjusting the distance between the left and right fixed brackets 36, fixed blocks 39, and the first clamping block 38 and the second clamping block 311 on them to accommodate steel pipes of different specifications. Using the slot opened on the left side of the fixed plate 4, the operator puts the two steel pipes to be welded between the first clamping block 38 and the second clamping block 311 on the left and right sides respectively, and starts the cylinder 37. The output end of the cylinder 37 drives the first clamping block 38 to move downward, cooperating with the second clamping block 311 to initially clamp the steel pipe. The rollers 312, which are fixedly connected to the inner sides of the first clamping block 38 and the second clamping block 311, allow the steel pipe to rotate during the clamping process. Since the three-jaw chuck 315 and the second clamping block 311 are on the same horizontal line, after the initial clamping is completed, the three-jaw chuck 315 can clamp one of the steel pipes and start the third servo motor 62 in the welding mechanism 6, whose output shaft drives the gear 63 to rotate. Because gear 63 meshes with cylindrical rack 65, and cylindrical rack 65 slides up and down on the inner wall of sliding sleeve 64, and at the same time, the top of I-plate 5 has a hole that matches cylindrical rack 65, and cylindrical rack 65 passes through and slides up and down in the hole, the rotation of gear 63 will cause cylindrical rack 65 to move up and down in the hole of sliding sleeve 64 and I-plate 5, thereby driving welding torch body 66 fixedly connected at the bottom to move up and down. Adjust welding torch body 66 to a suitable welding height, turn on welding torch body 66, first weld two steel pipes, and after welding a part, start the second servo motor 314, whose output end drives three-jaw chuck 315 to rotate. Since the steel pipe is firmly clamped by first clamping block 38, second clamping block 311 and three-jaw chuck 315, and the rollers 312 on the inner side of first clamping block 38 and second clamping block 311 can make the steel pipe rotate flexibly, the steel pipe will rotate accordingly. The welding torch body 66 then performs circumferential welding on the rotating steel pipe to complete the welding operation of the steel pipe frame.
