Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a steel structure welding equipment with automatic positioning function. Background Technology

[0002] In the manufacturing of metal cutting and welding equipment such as automatic and semi-automatic electric arc and plasma arc welding machines, steel pipe welding is a common task. During long-term use, steel pipes may become damaged or corroded, requiring replacement of the damaged parts. The usual repair method is to cut off the damaged section and butt weld a new steel pipe section to the original pipe. During the butt welding process, the two steel pipe sections are usually aligned manually, and the steel pipe is rotated manually or with auxiliary equipment during welding to ensure a uniform weld. However, this method is prone to causing the steel pipe to shift during rotation, resulting in inaccurate butt welding and thus affecting the welding quality.

[0003] In the existing technology, two pipe sections are clamped on different fixtures and then welded after being joined. However, different pipes have different lengths and different thicknesses between the inner and outer walls. When processing them, both the inner and outer walls of the pipes need to be welded. Conventional welding methods are inefficient and it is difficult to complete the welding work on both the inner and outer walls at the same time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a steel structure welding device with automatic positioning function to solve the problems mentioned in the background art. The present invention has a novel structure. After clamping and fixing two pipe sections, they are joined together. The processing component adjusts the position of the grinding wheel and the welding head according to the length and wall thickness of the pipe, so that they correspond to the inner and outer walls of the pipe. This allows for simultaneous processing and cleaning of the inner and outer walls of the pipe, thereby improving welding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure welding device with automatic positioning function, comprising a slide table, a fixed shaft seat fixed at one end of the top of the slide table, and a movable shaft seat slidably mounted at the other end of the top of the slide table. A rotating ring is rotatably mounted inside both the fixed and movable shaft seats, and a clamping assembly is mounted on the surface of the rotating ring. The clamping assembly includes a fourth electric push rod, and the fourth electric push rod is equidistantly fixed on the outer surface of the rotating ring. A clamping block is fixed to the extended end of the fourth electric push rod, and a pipe fitting is clamped inside the clamping block, the pipe fitting being located away from... One end of the clamping assembly is provided with a processing component, which includes a dust suction upper box. The dust suction upper box is provided on the top inner wall of the outer end of the tube of the movable shaft seat, and a dust suction lower box is provided on the bottom outer wall of the tube.

The top inner wall of the outer end of the tube of the fixed shaft seat is provided with a blower upper box, and a blower lower box is provided on the bottom outer wall of the tube. Welding heads are installed inside the blower upper box and the blower lower box. The dust suction upper box, the blower upper box, and the dust suction lower box and the blower lower box slide in contact with the inner wall and the outer wall of the tube, respectively.

[0006] Furthermore, screws are rotatably mounted on both sides of the slide via bearing seats, and screw blocks are threaded onto the surface of the screws, with the screw blocks being fixedly connected to both sides of the movable shaft seat.

[0007] Furthermore, the clamping assembly also includes a toothed ring, the outer ring of the rotating ring is fixed with a toothed ring, and a gear is meshed with the bottom of the toothed ring. The movable shaft seat and the fixed shaft seat are fixed with a drive motor located outside the gear, and the output end of the drive motor is fixedly connected to the gear.

[0008] Furthermore, a fifth electric push rod is fixed to the back of the clamping block, and a limit block is fixed to the extended end of the fifth electric push rod, the limit block being in extrusive contact with the inner wall of the pipe.

[0009] Furthermore, the processing component also includes a slide plate, on which the slide plate is slidably installed at the bottom of the vacuum cleaner lower box and the blower lower box, and a first electric push rod is fixed at the top of the slide plate. The extended end of the first electric push rod is fixedly connected to the bottom of the vacuum cleaner lower box and the blower lower box. The vacuum cleaner upper box, the blower upper box, the vacuum cleaner lower box, and the blower lower box are all provided with drainage grooves inside.

[0010] Furthermore, a first connecting plate is fixed to the side of the vacuum cleaner upper box and the blower upper box facing the clamping assembly. A second connecting plate is fixed to the bottom of the sliding plate at the first connecting plate, and the second connecting plate slides through the movable shaft seat and the fixed shaft seat. A telescopic frame is fixed to the outermost ends of the first connecting plate and the second connecting plate. A second electric push rod is fixed inside the movable shaft seat and the fixed shaft seat, and the extended end of the second electric push rod is fixedly connected to the bottom of the telescopic frame.

[0011] Furthermore, a vertical plate is fixed on the outer surface of the movable shaft seat and the fixed shaft seat, and a disc is fixed on the surface of the vertical plate. The disc and the axis of the pipe are in a straight line. A vertical frame is fixed on the surface of the disc, and an insert plate is slidably inserted into the inside of the vertical frame. The first connecting plate slides out from the top of the insert plate.

[0012] Furthermore, an arc block is fixed on the top outer surface of the insert plate, and an arc frame is fixed at the bottom of the limiting block, with the arc block slidingly engaging inside the arc frame.

[0013] Furthermore, brake blocks are provided on both sides of the bottom of the insert plate, and a bidirectional electric push rod is built into the bottom of the insert plate. The two extended ends of the bidirectional electric push rod inside the insert plate are fixedly connected to the brake blocks.

[0014] Furthermore, sliding frames are fixed on the outer surfaces of both sides of the upper and lower dust collection boxes, the upper and lower blower boxes, and sliders are slidably connected inside the sliding frames. A spring is fixed between the sliding frames and the sliders. A third electric push rod is fixed inside the sliders. A locking block is fixed on the top of the third electric push rod, and the locking block is in contact with the edge of the tube.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention uses clamping blocks and limiting blocks to press against the outer and inner walls of the pipe fitting tail end, respectively, thereby fixing the pipe fitting tail end. It can be used for processing pipe fittings of different sizes. After the two pipe fittings are joined, the drive motor drives the gear to rotate and mesh with the gear ring, thereby rotating the ring and driving the entire pipe fitting to rotate. During the rotation of the pipe fitting, the joining position of the two pipe fittings is ground and welded.

[0017] 2. The fourth electric push rod of the present invention adjusts the position of the clamping block according to the outer diameter of the pipe fitting, so that it presses against the outer wall of the pipe fitting. The fifth electric push rod adjusts the position of the limiting block, so that it presses against the inner wall of the pipe fitting. Because the arc block is engaged with the arc frame, the position of the first connecting plate is adjusted together with the limiting block. The telescopic frame extends and retracts to maintain the connection relationship between the first connecting plate and the second connecting plate. The position of the upper dust collection box and the upper blower box is automatically adjusted according to the wall thickness of the pipe fitting. Then, the position of the lower dust collection box and the lower blower box is adjusted by the first electric push rod so that they contact the bottom outer wall of the pipe fitting. According to the length of the pipe fitting, the telescopic frame is pushed to move so that the dust collection position and the welding position correspond to the pipe openings of the two pipe fittings respectively. The insert plate slides along the inside of the vertical frame. The bidirectional electric push rod built into the insert plate drives the brake block to press against the inner wall of the vertical frame, keeping the position of the first connecting plate unchanged.

[0018] 3. The present invention can drive the movement of the first connecting plate and the second connecting plate on both sides through the second electric push rod. Then, after the two pipes are connected, the grinding wheel and the welding head are respectively aligned with the connection position of the two pipes to perform grinding treatment first, and then the inner wall and outer wall welding processing is performed.

[0019] 4. In this invention, when two pipe fittings are joined, the locking blocks of the two sets of pipe fittings first come into contact. The locking blocks are moved downward by the third electric push rod to disengage from the pipe fittings. Then, the two locking blocks on the same straight line press against each other, causing the slider to slide along the slide frame until the two pipe fittings are aligned. At this time, the upper dust collection box, the lower dust collection box, the upper blower box, and the lower blower box also come into contact with each other. The position of the grinding wheel and the welding head can be adjusted by the second electric push rod. The position of welding or grinding inside the pipe fittings is determined according to the position of the lower dust collection box and the lower blower box.

[0020] 5. Compared with the prior art, the present invention clamps and fixes two pipe sections together by means of a clamping assembly, and adjusts the position of the grinding wheel and welding head according to the length and wall thickness of the pipe by means of a processing assembly, so that they correspond to the inner and outer walls of the pipe, thereby completing the processing and cleaning of the inner and outer walls of the pipe simultaneously and improving welding efficiency.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Please see Figures 1 to 9This invention provides a technical solution: a steel structure welding equipment with automatic positioning function, including a slide table 1. A fixed bearing 12 is fixed at one end of the top of the slide table 1, and a movable bearing 11 is slidably installed at the other end of the top of the slide table 1. A rotating ring 46 is rotatably installed inside both the fixed bearing 12 and the movable bearing 11, and a clamping assembly 4 is installed on the surface of the rotating ring 46. The clamping assembly 4 includes a fourth electric push rod 41. The fourth electric push rod 41 is fixed at equal intervals on the outer surface of the rotating ring 46, and a clamping block 42 is fixed at the extended end of the fourth electric push rod 41. A pipe fitting 2 is clamped inside the clamping block 42. A processing assembly 3 is provided at the end of the pipe fitting 2 away from the clamping assembly 4. The processing assembly 3 includes a dust collection upper box 31. The dust collection upper box 31 is provided on the top inner wall of the outer end of the pipe fitting 2 of the movable bearing 11, and a dust collection lower box 36 is provided on the bottom outer wall of the pipe fitting 2. The upper dust collection box 31 and the lower dust collection box 36 are both rotatably equipped with grinding wheels 32. The upper blower box 33 is provided on the top inner wall of the outer end of the tube 2 of the fixed shaft seat 12, and the lower blower box 37 is provided on the bottom outer wall of the tube 2. The upper blower box 33 and the lower blower box 37 are both equipped with welding heads 34. The upper dust collection box 31 and the upper blower box 33, and the lower dust collection box 36 and the lower blower box 37 slide in contact with the inner wall and outer wall of the tube 2, respectively. When using the device, the two sections of tube 2 are fixed inside the movable shaft seat 11 and the fixed shaft seat 12, respectively. The position of the processing component 3 is adjusted to match the wall thickness and length of the tube 2. Then the movable shaft seat 11 slides along the slide table 1, and the two sets of tubes 2 are connected. The clamping component 4 drives the tube 2 to rotate inside the movable shaft seat 11 and the fixed shaft seat 12. The processing component 3 grinds and welds the inner wall and outer wall of the tube 2.

[0033] In this embodiment, screws 13 are rotatably mounted on both sides of the slide table 1 via bearing seats, and screw blocks 14 are threaded onto the surface of the screws 13. The screw blocks 14 are fixedly connected to both sides of the movable shaft seat 11. The screws 13 are driven by a motor to clamp the two pipe fittings 2 onto the movable shaft seat 11 and the fixed shaft seat 12 respectively. Then, by rotating the screws 13, the screw blocks 14 cooperate with the screws 13 to drive the movable shaft seat 11 to move towards the fixed shaft seat 12, thereby achieving the docking of the two pipe fittings 2.

[0034] In this embodiment, the clamping assembly 4 further includes a toothed ring 47. The outer ring of the rotating ring 46 is fixed with the toothed ring 47, and the bottom of the toothed ring 47 is meshed with a gear 48. The movable shaft seat 11 and the fixed shaft seat 12 are located outside the gear 48 and are fixed with a drive motor 49. The output end of the drive motor 49 is fixedly connected to the gear 48. The back of the clamping block 42 is fixed with a fifth electric push rod 410, and the extended end of the fifth electric push rod 410 is fixed with a limit block 411. The limit block 411 is in contact with the inner wall of the pipe 2. By the clamping block 42 and the limit block 411 respectively contacting the outer and inner walls of the tail end of the pipe 2, the tail end of the pipe 2 is fixed. This can be used for processing pipes 2 of different sizes. After the two pipes 2 are joined, the drive motor 49 drives the gear 48 to rotate and mesh with the toothed ring 47, thereby rotating the rotating ring 46 and driving the entire pipe 2 to rotate. During the rotation of the pipe 2, the joining position of the two pipes 2 is ground and welded.

[0035] In this embodiment, the processing component 3 further includes a sliding plate 35. The sliding table 1 is slidably mounted with the sliding plate 35 at the bottom of the lower vacuum box 36 and the lower blower box 37. A first electric push rod 38 is fixed to the top of the sliding plate 35. The extended end of the first electric push rod 38 is fixedly connected to the bottom of the lower vacuum box 36 and the lower blower box 37. The upper vacuum box 31, the upper blower box 33, the lower vacuum box 36, and the lower blower box 37 are all provided with drainage grooves 313. A first connecting plate 39 is fixed to the side of the upper vacuum box 31 and the upper blower box 33 facing the clamping component 4. A second connecting plate 312 is fixed to the bottom of the sliding plate 35 at the bottom of the first connecting plate 39. The second connecting plate 312 slides through the movable shaft seat 11 and the fixed shaft seat 12. The first connecting plate 39 and the second connecting plate 312 are connected to each other. A telescopic frame 43 is fixed to the outermost end of plate 312. A second electric push rod 311 is fixed inside the movable shaft seat 11 and the fixed shaft seat 12, and the extended end of the second electric push rod 311 is fixedly connected to the bottom of the telescopic frame 43. A vertical plate 310 is fixed to the outer surface of the movable shaft seat 11 and the fixed shaft seat 12, and a disc 44 is fixed to the surface of the vertical plate 310. The disc 44 and the axis of the pipe 2 are in a straight line. A vertical frame 414 is fixed to the surface of the disc 44, and an insert plate 45 is slidably inserted into the interior of the vertical frame 414. The first connecting plate 39 slides out from the top of the insert plate 45. An arc block 413 is fixed to the top outer surface of the insert plate 45. An arc frame 412 is fixed to the bottom of the limiting block 411, and the arc block 413... 3. The sliding block 413 is fixed to the top outer surface of the insert plate 45, and the bottom of the limiting block 411 is fixed to the arc frame 412. The arc block 413 is slidably locked inside the arc frame 412. The first connecting plate 39 slides through the insert plate 45. In the initial stage, the fourth electric push rod 41 adjusts the position of the clamping block 42 according to the outer diameter of the pipe fitting 2, so that it presses against the outer wall of the pipe fitting 2. The fifth electric push rod 410 adjusts the position of the limiting block 411, so that it presses against the inner wall of the pipe fitting 2. Because the arc block 413 is locked with the arc frame 412, the position of the first connecting plate 39 is adjusted together with the limiting block 411. The telescopic frame 43 extends and retracts to maintain the connection relationship between the first connecting plate 39 and the second connecting plate 312. Adjustments are made according to the wall thickness of pipe fitting 2, automatically adjusting the positions of the upper vacuum box 31 and the upper blower box 33. Then, the positions of the lower vacuum box 36 and the lower blower box 37 are adjusted by the first electric push rod 38, so that they contact the bottom outer wall of pipe fitting 2. Then, according to the length of pipe fitting 2, the telescopic frame 43 is pushed to move, so that the vacuuming position and the welding position correspond to the pipe openings of the two pipe fittings 2 respectively. The insert plate 45 slides along the inside of the vertical frame 414. The bidirectional electric push rod built into the insert plate 45 drives the brake block 415 to press against the inner wall of the vertical frame 414, keeping the position of the first connecting plate 39 unchanged. When the rotating ring 46 rotates later, the arc block 413 will separate from the arc frame 412. At this time, the position of the first connecting plate 39 is locked by the insert plate 45 and the vertical frame 414, keeping it in contact with the inner wall of pipe fitting 2.This process involves grinding and welding the inner and outer walls of pipe fitting 2. The second electric push rod 311 moves the first connecting plate 39 and the second connecting plate 312 on both sides. After the two pipe fittings 2 are joined, the grinding wheel 32 and the welding head 34 are positioned at the joint of the two pipe fittings 2 respectively for grinding before welding the inner and outer walls. The upper and lower dust collection boxes 31 and 36 are equipped with existing vacuum cleaner structures to collect grinding debris, preventing it from falling into the pipe fittings 2 and affecting the welding effect. The lower and upper blower boxes 37 and 33 are equipped with fans to improve welding efficiency.

[0036] In this embodiment, sliding frames 314 are fixed to the outer surfaces of both sides of the upper vacuum box 31, lower vacuum box 36, upper blower box 33, and lower blower box 37. A slider 316 is slidably connected inside the sliding frame 314. A spring 315 is fixed between the sliding frame 314 and the slider 316. A third electric push rod 317 is fixed inside the slider 316. A locking block 318 is fixed to the top of the third electric push rod 317. The locking block 318 presses against the edge of the tube 2. Through the setting of the locking block 318, the upper vacuum box 31, lower vacuum box 36, upper blower box 33, and lower blower box 37 are respectively located on the top inner wall and bottom outer wall of the two tubes 2. And aligned with the opening of the pipe fitting 2, i.e. the welding position, when the two pipe fittings 2 are joined, the locking blocks 318 of the two sets of pipe fittings 2 first contact, and the locking blocks 318 are moved downward by the third electric push rod 317 to disengage from the locking with the pipe fitting 2. Then the two locking blocks 318 on the same straight line press against each other, causing the slider 316 to slide along the sliding frame 314 until the two pipe fittings 2 are aligned. At this time, the upper dust collection box 31, the lower dust collection box 36, the upper blower box 33 and the lower blower box 37 also contact each other. The position of the grinding wheel 32 and the welding head 34 can be adjusted by the second electric push rod 311. The position of welding or grinding inside the pipe fitting 2 is determined according to the position of the lower dust collection box 36 and the lower blower box 37.

[0037] When using the device, the clamping block 42 and the limiting block 411 press against the outer and inner walls of the tail end of the pipe fitting 2, respectively, thereby fixing the tail end of the pipe fitting 2. It can be used for processing pipe fittings 2 of different sizes. After the two pipe fittings 2 are joined, the drive motor 49 drives the gear 48 to rotate and mesh with the gear ring 47, thereby rotating the rotating ring 46 and driving the entire pipe fitting 2 to rotate. During the rotation of the pipe fitting 2, the joint position of the two pipe fittings 2 is ground and welded. The first connecting plate 39 slides through the insert plate 45. In the initial stage, the fourth electric push rod 41 adjusts the position of the clamping block 42 according to the outer diameter of the pipe fitting 2, so that it presses against the outer wall of the pipe fitting 2. The fifth electric push rod 410 adjusts the position of the limiting block 411, so that it presses against the outer wall of the pipe fitting 2. The inner wall of tube 2 is pressed into contact. Because the arc block 413 is engaged with the arc frame 412, the position of the first connecting plate 39 is adjusted together with the limiting block 411. The telescopic frame 43 extends and retracts to maintain the connection relationship between the first connecting plate 39 and the second connecting plate 312. The position of the upper dust collection box 31 and the upper blower box 33 is automatically adjusted according to the wall thickness of the tube 2. Then, the position of the lower dust collection box 36 and the lower blower box 37 is adjusted by the first electric push rod 38 so that they contact the bottom outer wall of the tube 2. Then, according to the length of the tube 2, the telescopic frame 43 is pushed to move so that the dust collection position and the welding position correspond to the openings of the two tubes 2 respectively. The insert plate 45 slides along the inside of the vertical frame 414. The bidirectional electric push rod built into the insert plate 45 drives the brake block 4. 15 is pressed against the inner wall of the vertical frame 414, keeping the position of the first connecting plate 39 unchanged. When the rotating ring 46 rotates, the arc block 413 will separate from the arc frame 412. At this time, the position of the first connecting plate 39 is locked by the insert plate 45 and the vertical frame 414, keeping it in contact with the inner wall of the pipe 2, thereby grinding and welding the inner and outer walls of the pipe 2. The second electric push rod 311 can drive the movement of the first connecting plate 39 and the second connecting plate 312 on both sides. After the two pipes 2 are connected, the grinding wheel 32 and the welding head 34 are respectively aligned with the connection positions of the two pipes 2. Grinding is performed first, and then the inner and outer walls are welded. Through the setting of the clamping block 318, the upper dust collection box 31, the lower dust collection box 36, the upper blower box 33 and the blower are connected. The lower box 37 is located on the top inner wall and bottom outer wall of the two pipe fittings 2 respectively, and is aligned with the pipe opening of the pipe fitting 2, i.e. the welding position. When the two pipe fittings 2 are connected, the locking blocks 318 of the two sets of pipe fittings 2 first contact. The locking blocks 318 are moved downward by the third electric push rod 317 to disengage from the pipe fittings 2. Then, the two locking blocks 318 on the same straight line press against each other, causing the slider 316 to slide along the sliding frame 314 until the two pipe fittings 2 are aligned. At this time, the upper vacuum box 31, the lower vacuum box 36, the upper blower box 33 and the lower blower box 37 also contact each other. The position of the grinding wheel 32 and the welding head 34 can be adjusted by the second electric push rod 311. The position of welding or grinding inside the pipe fitting 2 is determined according to the position of the lower vacuum box 36 and the lower blower box 37.
