[0027] Please refer to Figure 1-7 , and the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0028] The industrial welding anti-deformation device of the present utility model includes a rotating disk 1. A fixing device 2 is arranged on the upper end surface of the rotating disk 1. The fixing device 2 is used to fix the steel plate 5. A positioning device 3 is also arranged on the upper end surface of the rotating disk 1. The positioning device 3 is used to position and fix the reinforcing rib 4 on the steel plate 5. The rotating disk 1 is rotatably connected to the workbench 6 below. When the welding device welds the joint of the reinforcing rib 4 and the steel plate 5, by rotating the rotating disk 1, the rotating disk 1 drives the steel plate 5 and the reinforcing rib 4 to rotate synchronously through the fixing device 2 and the positioning device 3, so as to facilitate the all-round welding of the steel plate 5 and the reinforcing rib 4, ensuring the welding quality of the reinforcing rib 4 and the steel plate 5. At the same time, since the reinforcing rib 4 and the steel plate 5 can be welded all-round, it prevents local deformation caused by different welding degrees of the parts that are inconvenient to weld and the parts that are convenient to weld due to angle problems, effectively ensuring the welding strength and quality. The motor 8 is fixedly arranged on the lower end surface of the workbench 6 through the fixed plate 7. The output shaft of the motor 8 is fixedly arranged with the rotating shaft 9 coaxially fixed on the lower end surface of the rotating disk 1. The rotating shaft 9 is rotatably connected to the workbench 6. Starting the motor 8 drives the rotating disk 1 to rotate through the rotating shaft 9, achieving the purpose of the rotating disk 1 rotating when welding the reinforcing rib 4 and the steel plate 5, and further achieving the purpose of driving the steel plate 5 and the reinforcing rib 4 to rotate synchronously.

[0029] In this embodiment, the fixing device 2 includes two pressing rods 10 symmetrically arranged on the upper end surface of the rotating disk 1 from left to right. Clamping rods 11 are arranged at both ends of the two pressing rods 10. Accommodating grooves 12 are formed in the corresponding positions of the upper end surface of the workbench 6 along the front-rear direction. A groove body 13 is slidably arranged in each accommodating groove 12 along the up-down direction. The two clamping rods 11 on the same side are arranged in the corresponding groove body 13. A driving device is arranged in the rotating disk 1, and the execution ends of the driving device are connected to the two groove bodies 13. When in use, first pass the steel plate 5 through the gap between the two pressing rods 10 and the rotating disk 1, and then drive the two groove bodies 13 to move downward through the driving device, so that each groove body 13 drives the pressing rod 10 to move downward through the corresponding two clamping rods 11, achieving the purpose of clamping the steel plate 5 by the two pressing rods 10.

[0030] In this embodiment, a connecting plate 14 fixedly arranged on the lower end surfaces of the two groove bodies 13 is arranged in the rotating disk 1. The connecting plate 14 is slidably arranged in a transverse cavity 15 formed in the rotating disk 1 along the up-down direction. Both ends of the transverse cavity 15 communicate with the corresponding accommodating grooves 12. The driving device includes a threaded rod 16 arranged vertically in the rotating disk 1. The threaded rod 16 is threadedly connected to the connecting plate 14. Both ends of the threaded rod 16 are rotatably connected to the rotating disk 1. The driving device further includes a first bevel gear 17 and a second bevel gear 18 fixedly arranged at the top end of the threaded rod 16. The first bevel gear 17 and the second bevel gear 18 are meshed with each other. A transmission rod 19 is fixedly arranged on the front side surface of the first bevel gear 17. The front end of the transmission rod 19 protrudes from the outer surface of the rotating disk 1 and is fixedly provided with a driving part 20. The transmission rod 19 is rotatably connected to the rotating disk 1. When in use, rotate the driving part 20 through a tool, so that the driving part 20 drives the threaded rod 16 to rotate through the transmission rod 19, the first bevel gear 17 and the second bevel gear 18 in sequence, so that the threaded rod 16 drives the connecting plate 14 to move up and down, and further enables the connecting plate 14 to drive the pressing rod 10 to move up and down through the groove body 13 and the clamping rod 11 in sequence, achieving the purpose of driving the two pressing rods 10 to move synchronously up and down by rotating the transmission rod 19. Clamp the steel plate 5 by moving the pressing rod 10 downward, and move the pressing rod 10 upward to facilitate the insertion of the steel plate 5 into the gap between the pressing rod 10 and the rotating disk 1.

[0031] In order to achieve the purpose of facilitating the adjustment of the distance between the corresponding two clamping rods 11, in this embodiment, each clamping rod 11 is slidably arranged in the corresponding groove 13 in the front-rear direction. A regulating bolt 21 is rotatably connected in each clamping rod 11, and each regulating bolt 21 is threadedly connected to the corresponding pressure rod 10. When it is necessary to adjust the distance between the corresponding two clamping rods 11, by rotating the regulating bolt 21, the regulating bolt 21 is extended into or extended out of the pressure rod 10, so as to drive the clamping rod 11 to approach or move away from the pressure rod 10, thereby achieving the purpose of adjusting the distance between the corresponding two clamping rods 11 to meet the fixed clamping of steel plates 5 with different widths and sizes.

[0032] In this embodiment, the positioning device 3 includes a vertical rod 22 fixedly arranged on the upper end surface of the rotating disk 1. A top plate 23 is fixedly arranged along the radial direction at the top of the vertical rod 22. A pressure column 24 is slidably arranged in the top plate 23 in the up-down direction. A disk 25 is coaxially arranged on the upper part of the outer surface of the pressure column 24. A spring 26 is arranged between the disk 25 and the top plate 23. The top end of the spring 26 is fixedly arranged with the disk 25, and the bottom end of the spring 26 is fixedly arranged with the upper end surface of the top plate 23. A pressing plate 27 is fixedly arranged at the bottom end of the pressure column 24. During use, first, the steel plate 5 is fixed by the fixing device 2, then the stiffening rib 4 is vertically placed on the steel plate 5. The pressing plate 27 is manually lifted upward to make the pressure column 24 move upward. The upward movement of the pressure column 24 stretches the spring 26 through the disk 25 until the pressing plate 27 is located on the upper end surface of the stiffening rib 4, and then the pressing plate 27 is released, so that the pressing plate 27 is pressed tightly on the upper end surface of the stiffening rib 4 under the action of the retraction force of the spring 26, so that the stiffening rib 4 is positioned and fixed on the upper end surface of the steel plate 5, achieving the purpose of positioning and fixing the stiffening rib 4 on the upper end surface of the steel plate 5.

[0033] To achieve the purpose of adjustable pressure applied by the pressing plate 27 to the stiffening rib 4, in this embodiment, an external thread is provided on the outer surface of the pressing column 24. A movable sleeve 28 is rotatably connected inside the disc 25. A nut 29 is fixedly arranged on the upper end surface of the movable sleeve 28. The nut 29 is threadedly connected to the pressing column 24 through the external thread of the pressing column 24, and the movable sleeve 28 is sleeved on the pressing column 24. When it is necessary to adjust the pressure applied by the pressing plate 27 to the stiffening rib 4, by rotating the nut 29, the nut 29 moves up and down on the pressing column 24, so as to stretch or compress the spring 26 by the disc 25, thereby achieving the purpose of adjusting the tensile force of the spring 26. After the upper end surface of the stiffening rib 4 is pressed by the pressing plate 27, by rotating the nut 29 to drive the disc 25 to move upward, the disc 25 further stretches the spring 26, increasing the tensile force of the spring 26. Thus, the force of the spring 26 pulling the pressing column 24 downward through the disc 25 increases, further increasing the pressing force of the pressing plate 27 on the upper end surface of the stiffening rib 4. The pressing of the pressing plate 27 on the stiffening rib 4 is achieved through the tensile force of the spring 26, and the problem that the pressing plate 27 is lifted upward due to the force during welding will not occur, because the pressing plate 27 only positions and fixes the stiffening rib 4. At the initial stage of welding, the relative positions of the stiffening rib 4 and the steel plate 5 are fixed due to welding.

[0034] To increase the stability of the up-and-down movement of the pressing column 24 in the top plate 23, in this embodiment, two rotation-limiting blocks 31 are fixedly arranged along the axial direction inside the through hole 30 of the top plate 23 for passing through the pressing column 24. A rotation-limiting groove 32 adapted to the rotation-limiting blocks 31 is axially provided on the outer surface of the pressing column 24. When the pressing column 24 moves up and down in the top plate 23, due to the action of the rotation-limiting blocks 31 and the rotation-limiting groove 32, the pressing column 24 can only move up and down and cannot rotate, increasing the stability of the up-and-down movement of the pressing column 24. At the same time, when adjusting the tensile force of the spring 26 by rotating the nut 29, the nut 29 can rotate relative to the pressing column 24 without additionally clamping the pressing column 24 to prevent it from rotating, which is convenient for adjusting the tensile force of the spring 26.

[0035] To increase the stability of the movement of the clamping rod 11 in the groove body 13, in this embodiment, guide blocks are fixedly arranged on the left and right side surfaces of the clamping rod 11. Guide grooves 33 adapted to the guide blocks are provided on the inner side walls of the groove body 13 at positions corresponding to the guide blocks along the front-back direction. When the clamping rod 11 moves back and forth in the groove body 13, the stability of the movement of the clamping rod 11 in the groove body 13 is increased by the limitation of the guide blocks and the guide grooves 33.

[0036] In order to increase the stability of the up-and-down movement of the groove body 13 within the receiving groove 12, in this embodiment, slide rails 34 are fixedly arranged on both the left and right side surfaces of the groove body 13. The inner side walls of the receiving groove 12 at positions corresponding to the guide rails are provided with chutes adapted to the slide rails 34 in the vertical direction. When the groove body 13 moves up and down, the stability of the up-and-down movement of the groove body 13 within the receiving groove 12 is increased by the restriction of the up-and-down movement of the slide rails 34 within the chutes.

[0037] In order to increase the stability of the up-and-down movement of the connecting plate 14 within the horizontal cavity 15, in this embodiment, two guide rods 35 are fixedly arranged in the horizontal cavity 15 in the up-and-down direction. The two guide rods 35 are located on the left and right sides of the threaded rod 16, and both of the two guide rods 35 are sleeved with the connecting plate 14. When the connecting plate 14 moves up and down, the connecting plate 14 moves up and down on the two guide rods 35 simultaneously, increasing the stability of the up-and-down movement of the connecting plate 14.

[0038] The working principle of the present utility model: During use, first, the steel plate 5 is passed through the gap between the pressure rod 10 and the rotating disk 1. Then, through the rotation driving part 20, the driving part 20 drives the pressure rod 10 to move downward in sequence through the transmission rod 19, the first bevel gear 17, the second bevel gear 18, the threaded rod 16, the connecting plate 14, the groove body 13, and the clamping rod 11, so that the pressure rod 10 presses and fixes the steel plate 5. Then, the reinforcing rib 4 is vertically placed on the steel plate 5. By manually lifting the pressing plate 27 upward, the pressing column 24 moves upward. The upward movement of the pressing column 24 stretches the spring 26 through the disk 25 until the pressing plate 27 is located on the upper end surface of the reinforcing rib 4. Then, the pressing plate 27 is released, so that the pressing plate 27 presses on the upper end surface of the reinforcing rib 4 under the action of the retraction force of the spring 26, positioning and fixing the reinforcing rib 4 on the upper end surface of the steel plate 5, achieving the purpose of positioning and fixing the reinforcing rib 4 on the upper end surface of the steel plate 5. Then, the welding device welds the joint of the reinforcing rib 4 and the steel plate 5. When the welding device welds the joint of the reinforcing rib 4 and the steel plate 5, the rotating disk 1 is rotated by the motor 8, so that the rotating disk 1 drives the steel plate 5 and the reinforcing rib 4 to rotate through the fixing device 2 and the positioning device 3, facilitating all-round welding of the steel plate 5 and the reinforcing rib 4, ensuring the welding quality of the reinforcing rib 4 and the steel plate 5. At the same time, since the reinforcing rib 4 and the steel plate 5 can be welded all-round, it prevents local deformation caused by different welding degrees of the parts that are inconvenient to weld due to angle problems and the parts that are convenient to weld, effectively ensuring the welding strength and quality.
