Description

Technical Field

[0001] This invention relates to the field of welding platform technology, specifically a steel pipe beam welding operation platform. Background Technology

[0002] Steel pipe beams are an important transverse component used in steel structures. They are mainly made of steel materials such as shaped steel and steel plates and play a core role in supporting and transmitting loads. The cross-section of steel pipe beams is generally a circular hollow structure or a rectangular hollow structure. In the splicing of steel pipe beams, welding technology is often used to weld two sets of steel pipe beams together.

[0003] To ensure the straightness of the welded steel pipe beam, it is often necessary to clamp and fix the steel pipe beam with a special platform and accurately position it before welding robots or manual welding machines can be used for welding operations. However, due to the different shapes of the steel pipe beam cross-section, the clamping mechanism of the platform often needs to be disassembled and replaced to adapt to the shape of the steel pipe beam, which is very inconvenient. At the same time, since the end faces of the steel pipe beams are not necessarily completely flush, the weld width is different, which is not conducive to subsequent welding operations, increasing the welding difficulty and hindering the improvement of welding quality. Summary of the Invention

[0004] The purpose of this invention is to provide a steel pipe beam welding operation platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0010] As a further improvement of the present invention: the displacement clamping assembly includes a sliding frame slidably connected to the track, the sliding frame being fixedly connected to multiple sets of symmetrically arranged third active telescopic frames, the multiple sets of third active telescopic frames arranged on the same side of the sliding frame being arranged in a straight line, the multiple sets of third active telescopic frames arranged in the same row being fixedly connected to a support frame, the two sets of support frames abutting against each other, the support frame being movably connected to the sliding frame, the sliding frame being fixedly connected to multiple sets of fourth active telescopic frames, the moving ends of the multiple sets of fourth active telescopic frames being fixedly connected to a V-shaped bracket, the V-shaped bracket being movably connected to two sets of support frames, the sliding frame being fixedly connected to four sets of symmetrically arranged fifth active telescopic frames, each pair of fifth active telescopic frames being fixedly connected to a set of side pressure plates, the sliding frame being fixedly connected to multiple sets of sixth active telescopic frames, the moving ends of the multiple sets of sixth active telescopic frames being fixedly connected to a pressure pipe frame.

[0011] As a further improvement of the present invention: the double-sided grinding part includes two sets of third motors fixedly connected to the suspension, the two sets of third motors are symmetrically arranged on the suspension, the output shaft of the third motor is connected to an abutment plate, and the abutment plate is fixedly connected to a grinding disc.

[0012] As a further improvement of the present invention: the rotation drive unit includes a frame fixedly connected to the suspension, a fourth motor fixedly connected to the frame, a gear fixedly connected to the output shaft of the fourth motor, a gear meshing with a gear ring, a rotating frame fixedly connected to the gear ring, the rotating frame rotatably connected to the frame, and the rotating frame fixedly connected to two sets of plate frames.

[0015] As a further improvement of the present invention: a waste bin is provided below the grinding disc, and the waste bin is fixedly connected to the base.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In use, the displacement clamping assembly selectively adjusts its structure according to the shape of the steel pipe beam. Then, the two sets of steel pipe beams to be welded are placed on the two sets of displacement clamping assemblies respectively. The displacement clamping assembly positions and clamps the steel pipe beams, suspending the ends to be welded. The first active telescopic frame moves the suspension to adjust the height of the rotating drive unit, allowing it to move between the two sets of steel pipe beams. The second motor drives the second lead screw to rotate, which in turn drives the synchronous frame to move along the fixed frame. The synchronous frame moves the sleeve frame, which in turn moves the extension shaft. The extension shaft moves by driving the stepped shaft. The stepped shaft drives the moving frame to move. If the end face of the steel pipe beam is circular, the moving frame is arranged in a longitudinal straight line. The first motor drives the first lead screw to rotate, and then the first lead screw drives the sliding block to move to adjust the position of the elastic positioning component. As the guide pushing mechanism drives the displacement clamping components to approach each other, the elastic positioning component abuts against the end face of the circular tubular steel pipe beam. Then, the rotation drive unit drives the plate frame to rotate, causing the elastic positioning component to move along the end face of the circular tubular steel pipe beam. At the same time, the elastic positioning component performs positioning work on the end face of the circular tubular steel pipe beam to determine the flatness of the end face of the circular tubular steel pipe beam ... The first motor drives the first lead screw to rotate, and then the first lead screw drives the sliding block to move to adjust the position of the elastic positioning component. The elastic positioning component performs positioning work on the end face of the circular tubular steel pipe beam to determine the flatness of the end face of the circular tubular steel pipe beam. The second motor drives the first lead screw to rotate, and then the second lead screw drives the sliding block to move to adjust the position of the elastic positioning component. The second lead screw drives the second lead If the surface is rectangular, the moving frames are arranged parallel to each other. As the guiding and pushing mechanism drives the displacement clamping components to approach each other, the elastic measuring components abut against the end face of the square tubular steel pipe beam. The first motor drives the first lead screw to rotate, and then the first lead screw drives the sliding block to move, thereby adjusting the position of the elastic measuring components. This causes the elastic measuring components to move along the two sets of strip-shaped end faces of the square tubular steel pipe beam. Then, the guiding and pushing mechanism drives the displacement clamping components to move away from each other, and the rotating drive unit drives the plate frame to rotate. The moving displacement clamping components drive the square tubular steel pipe beam to move towards the elastic measuring components. The elastic measuring components move with the sliding block to abut against the end face of the square tubular steel pipe beam. The other two sets of strip-shaped end faces of the square tubular steel pipe beam are measured to determine the flatness of the end faces. If the end faces of the steel pipe beams need to be corrected and positioned, the first active telescopic frame moves the suspension, and the double-sided grinding part moves between the two sets of steel pipe beams. As the guide pushing mechanism moves the displacement clamping assembly closer to the double-sided grinding part, the end faces of the steel pipe beams are ground to flatten them. Then, the first active telescopic frame moves the suspension back to its original position, and the guide pushing mechanism moves the displacement clamping assembly, causing the two sets of steel pipe beams to abut against each other, thus completing the positioning of the steel pipe beams and providing a limit for subsequent welding operations. This invention uses the cooperation of the deformation positioning structure and the positioning calibration structure to position and clamp steel pipe beams of different shapes, then performs end face positioning and measurement on the steel pipe beams, and corrects the end faces of the steel pipe beams, thereby facilitating accurate mutual positioning and docking of the steel pipe beams, improving the quality of subsequent welding processing, and saving manpower.

The guide pushing mechanism 3 is connected to a displacement clamping assembly 4. The displacement clamping assembly 4 is used to perform positioning operations on the steel pipe beam.

[0035] A positioning calibration structure 5 connected to the base 1 includes a first active telescopic frame 6 connected to the base 1. A suspension 7 is fixedly connected to the moving end of the first active telescopic frame 6. A double-sided grinding part 8 is connected to the suspension 7. An end-face scanning mechanism 9 is connected to the suspension 7. The end-face scanning mechanism 9 includes a rotation drive part 10 connected to the suspension 7. Two symmetrically arranged plate frames 11 are fixedly installed on the rotation drive part 10. Two sets of guide grooves 12 are provided on each plate frame 11. Each guide groove group 12 consists of two parallel hook-shaped grooves 13. Two sets of stepped shafts 14 are slidably connected to the guide groove group 12. One set of stepped shafts 14 is fixedly connected to an extension shaft 15. Both sets of stepped shafts 14 are jointly fixedly connected to a plate... The frame 11 has a sliding frame 16, which is fixedly connected to a first motor 17. The output shaft of the first motor 17 is fixedly connected to a first lead screw 18, which is rotatably connected to the frame 16. The first lead screw 18 is threadedly connected to a sliding block 19, which is slidably connected to the frame 16. The sliding block 19 is connected to an elastic positioning component 20. The plate frame 11 is fixedly connected to a fixed frame 21, which is fixedly connected to a second motor 22. The output shaft of the second motor 22 is fixedly connected to a second lead screw 23, which is threadedly connected to a synchronization frame 24. The synchronization frame 24 is slidably connected to the fixed frame 21, and the synchronization frame 24 is fixedly connected to a sleeve 25, which is slidably connected to an extension shaft 15.

[0036] In use, the displacement clamping assembly 4 selectively adjusts its structure according to the shape of the steel pipe beam. Then, the two sets of steel pipe beams to be welded are placed on the two sets of displacement clamping assemblies 4 respectively. The displacement clamping assembly 4 positions and clamps the steel pipe beams, suspending the ends of the steel pipe beams to be welded. The first active telescopic frame 6 drives the suspension 7 to move, adjusting the height of the rotation drive unit 10 so that the rotation drive unit 10 moves between the two sets of steel pipe beams. The second motor 22 drives the second lead screw 23 to rotate, and the second lead screw 23 drives the synchronous frame 24 to move along the fixed frame 21. The synchronous frame 24 drives the sleeve frame 25 to move, so that the sleeve frame 25 drives the extension shaft 15 to move. The extension shaft 15 drives the stepped shaft 14. The movement is such that the stepped shaft 14 drives the moving frame 16 to move. If the end face of the steel pipe beam is circular, the moving frame 16 is arranged in a longitudinal straight line. The first motor 17 drives the first lead screw 18 to rotate, and then the first lead screw 18 drives the sliding block 19 to move, so as to adjust the position of the elastic positioning component 20. As the guide pushing mechanism 3 drives the displacement clamping component 4 to approach each other, the elastic positioning component 20 abuts against the end face of the circular tubular steel pipe beam. Then the rotation drive unit 10 drives the plate frame 11 to rotate, so that the elastic positioning component 20 moves along the end face of the circular tubular steel pipe beam. At the same time, the elastic positioning component 20 performs positioning work on the end face of the circular tubular steel pipe beam to determine the flatness of the end face of the circular tubular steel pipe beam. If the end face of the steel pipe beam is rectangular, the moving frames 16 are arranged parallel to each other. As the guide pushing mechanism 3 drives the displacement clamping components 4 to approach each other, the elastic positioning component 20 abuts against the end face of the square tubular steel pipe beam. The first motor 17 drives the first lead screw 18 to rotate, and then the first lead screw 18 drives the sliding block 19 to move, so as to adjust the position of the elastic positioning component 20, so that the elastic positioning component 20 moves along the two sets of strip-shaped end faces of the square tubular steel pipe beam. Then the guide pushing mechanism 3 drives the displacement clamping components 4 to move away from each other, and the rotation drive unit 10 drives the plate frame 11 to rotate. The moving displacement clamping components 4 drive the square tubular steel pipe beam to move towards the elastic positioning component 20. 20 moves with sliding block 19 to measure the other two sets of strip-shaped end faces of the square tubular steel pipe beam to determine the flatness of the end face of the square tubular steel pipe beam. If the end face of the steel pipe beam needs to be corrected and positioned, the first active telescopic frame 6 drives the suspension 7 to move, and the double-sided grinding part 8 moves between the two sets of steel pipe beams. As the guide pushing mechanism 3 drives the displacement clamping assembly 4 to approach the double-sided grinding part 8, the end face of the steel pipe beam is ground to flatten the end face of the steel pipe beam. Then the first active telescopic frame 6 drives the suspension 7 to reset, and the guide pushing mechanism 3 drives the displacement clamping assembly 4 to move, so that the two sets of steel pipe beams abut against each other to complete the positioning of the steel pipe beam and provide a limit for subsequent welding operations.This invention utilizes the cooperation between the deformation positioning structure 2 and the positioning calibration structure 5 to position and clamp steel pipe beams of different shapes. Then, the end face of the steel pipe beam is positioned and measured, and the end face of the steel pipe beam is corrected. This facilitates accurate mutual positioning and docking of the steel pipe beams, thereby improving the quality of subsequent welding processes and saving manpower.

Two sets of second active telescopic frames 28 are fixedly connected to the base frame 26, and the moving ends of both sets of second active telescopic frames 28 are fixedly connected to the displacement clamping assembly 4. The second active telescopic frames 28 are used to drive the displacement clamping assembly 4 to move along the two sets of rails 27 to adjust the position of the displacement clamping assembly 4.

The moving ends of the multiple sets of sixth active telescopic frames 36 are jointly fixedly connected to a pressure pipe frame 37. If the end face of the steel pipe beam is rectangular, the third active telescopic frame 30 pushes the support frame 31, causing the two sets of support frames 31 to abut against each other. The support frame 31 and the sliding frame 29 together provide planar support for the square tubular steel pipe beam. The fourth active telescopic frame 32 drives the V-shaped bracket 33 to abut against the bottom of the support frame 31 to prevent the support frame 31 from bending. The fifth active telescopic frame 34 drives the side pressure plate 35 to clamp and fix the square tubular steel pipe beam. If the end face of the steel pipe beam is circular, the fourth active telescopic frame 32 drives... The moving V-shaped bracket 33 descends, the third active telescopic frame 30 drives the support frame 31 to descend, and then the fourth active telescopic frame 32 drives the V-shaped bracket 33 to rise, and the V-shaped bracket 33 provides support for the circular tubular steel pipe beam. Then the sixth active telescopic frame 36 drives the pressing frame 37 to move down, so that the pressing frame 37 applies pressure to the V-shaped bracket 33 to limit and position the circular tubular steel pipe beam on the V-shaped bracket 33, so that the displacement clamping assembly 4 can be used to position and limit steel pipe beams of different shapes.

[0039] In one embodiment, the double-sided grinding section 8 includes two sets of third motors 38 fixedly connected to the suspension 7. The two sets of third motors 38 are symmetrically arranged on the suspension 7.

The rotating frame 45 is rotatably connected to the frame 41 and fixedly connected to two sets of plate frames 11. The fourth motor 42 drives the gear 43 to rotate, which in turn drives the gear ring 44 to rotate. The gear ring 44 then moves the rotating frame 45, causing it to rotate relative to the frame 41. The rotating frame 45 also drives the plate frames 11 to rotate, thereby adjusting the rotation angle of the plate frames 11.

[0041] In one embodiment, a first spring 46 is fixedly installed inside the track 27. The first spring 46 is fixedly connected to a slide bar 47 that is slidably connected to the track 27. The slide bar 47 is fixedly connected to a track block 48, and the track block 48 is fixedly connected to a stop block 49. As the sliding frame 29 moves onto the track block 48 and abuts against the stop block 49, the track block 48 pulls the slide bar 47, the first spring 46 is stretched, and the slide bar 47 slides out of the track 27. The track block 48 provides auxiliary support for the sliding frame 29, while preventing the track 27 from extending under the grinding disc 40 to avoid grinding debris falling onto the track 27.
