Description

Technical Field

[0001] This utility model belongs to the field of metal guardrail processing, and specifically relates to a fixing device for welding metal guardrails. Background Technology

[0002] Guardrails are mainly used in residential areas, highways, commercial areas, and public places to protect personal safety and equipment. Guardrails are ubiquitous in our lives. For aesthetic purposes, existing metal guardrails often feature openwork designs. During the manufacturing process, welding equipment is used to weld two short pipes together to form a suitable height for the guardrail. Therefore, welding equipment is indispensable in guardrail manufacturing. Furthermore, the guardrail needs to be secured during welding to facilitate the process.

[0003] Chinese Patent No. CN221337323U discloses a fixing device for welding metal railings, relating to the field of fixing device technology. The device includes a support base, a slider internally connected to the support base, a connecting block fixedly connected to the top of the slider, the connecting block being slidably connected to the support base, a base fixedly connected to the top of the connecting block, a clamping block contacting the top of the base, and a limiting block fixedly connected to the lower end of the clamping block, the limiting block being slidably connected to the base. This utility model provides a fixing device for welding metal railings. By incorporating components such as a threaded rod and bases, rotating the threaded rod causes two bases to move, which in turn move the railings closer together, thus improving the connection between the two railings. This solves the problem of inconvenience in connecting two railings to be welded when using fixing devices for welding metal railings.

[0004] As can be seen from the above structure, by setting up components such as threaded rods and bases, the threaded rods can be rotated to drive the two bases to move, so that the two bases can drive the guardrails to move closer to each other, thereby making the two guardrails better connected. However, the above device cannot rotate during use, which means that when the lower end of the guardrail needs to be welded, the position of the guardrail needs to be readjusted before welding, thus reducing the practicality of the device.

The dual-axis motor is started to rotate the shaft, which in turn drives the limiting active synchronous wheel. The rotation of the active synchronous wheel, under the action of the synchronous belt, causes the driven synchronous wheel to rotate, which in turn causes the fixing component to rotate. This rotation of the fixing component allows the pipes to be rotated, making welding more convenient and allowing for easy adjustment during welding.

[0016] Secondly, this utility model, through its fixed assembly, allows for the fixing and welding of two shorter pipe fittings. The pipe fitting ends are placed inside the disc of the fixed assembly, located inside the threaded clamping block. Rotating the disc drives the active bevel gear, which in turn drives the driven bevel gear, which in turn drives the fixed screw. The rotation of the fixed screw causes the threaded clamping block to move closer together, thus fixing the pipe fitting. Furthermore, the multi-jaw fixing mechanism allows for the fixing of pipe fittings of different shapes, ensuring a more secure and stable fix without any shaking. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a metal guardrail welding fixing device includes a plate 1, an adjustment component 2 fixedly connected to the upper end of the plate 1, fixing components 3 provided on the outer side of the adjustment component 2, a rotating component 4 fixedly connected to the upper end of the plate 1 on one side of the adjustment component 2, a bracket 5 fixedly connected to the upper end of the plate 1, an electric push rod 6 fixedly connected to the upper end of the bracket 5, and a welding head 7 fixedly connected to the lower end of the electric push rod 6 through the bracket 5. The rotating component 4 includes a dual-axis motor 41 disposed on the upper end of the plate 1, fixing plates 42 fixedly connected to both sides of the dual-axis motor 41 on the upper end of the plate 1, shafts 43 fixedly connected to the output shafts of the dual-axis motor 41, a driving synchronous wheel 44 slidably connected to the surface of the shaft 43, the driving synchronous wheel 44 and the shaft 43 mutually limiting connection, driven synchronous wheels 46 fixedly connected to the outer side of the fixing components 3, the driving synchronous wheel 44 and the driven synchronous wheel 46 mutually driving connection through a synchronous belt 45, and the other end of the shaft 43 rotatably connected to the fixing plate 42.

[0024] refer to Figure 1 and Figure 3The adjusting assembly 2 includes an adjusting frame 21 disposed on the upper end of the plate 1. A bidirectional screw 22 is rotatably connected inside the adjusting frame 21. Threaded parts 23 are threadedly connected to both sides of the outer surface of the bidirectional screw 22. A connecting plate 24 is fixedly connected to the upper end of each threaded part 23. A fixing plate 25 is fixedly connected to the upper end of the connecting plate 24. A fixing assembly 3 is rotatably connected to the surface of the fixing plate 25. An adjusting motor 26 is fixedly connected to the outer side of the adjusting frame 21. The output shaft of the adjusting motor 26 is fixedly connected to the bidirectional screw 22. After the pipe is fixed by the fixing assembly 3, the adjusting motor 26 is controlled to rotate, which drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 causes the threaded parts 23 to move. The movement of the threaded parts 23 causes the fixing plate 25 to move closer together, so that the pipe can be connected when the fixing plate 25 moves closer together, which facilitates subsequent welding after the connection is completed.

[0025] refer to Figure 2 A sliding hole 8 is provided on one side of the adjusting frame 21. A connecting rod 9 is fixedly connected to one side of the threaded part 23 located in the sliding hole 8. The connecting rod 9 and the sliding hole 8 are slidably connected to each other. A ring 10 is rotatably connected to the outside of the active synchronous wheel 44. The ring 10 and the shaft 43 are sleeved together. The other end of the connecting rod 9 is fixedly connected to the ring 10. The connecting rod 9 and the ring 10 are used to connect the threaded part 23 and the active synchronous wheel 44, so that the active synchronous wheel 44 can move with the movement of the fixed component 3 when the threaded part 23 moves.

[0026] refer to Figure 2 The outer surface of the shaft 43 is mutually limited and inserted into the active synchronous wheel 44. The inner side of the active synchronous wheel 44 is provided with a limit groove 12. The outer surface of the shaft 43 is fixedly connected with a limit block 11. The limit block 11 and the limit groove 12 are mutually limited and inserted into each other. The limit groove 12 and the limit block 11 are provided so that the active synchronous wheel 44 can slide on the surface of the shaft 43. At the same time, under the limit condition, the active synchronous wheel 44 can rotate with the rotation of the shaft 43.

[0027] refer to Figure 3 The lower end of the plate 1 is fixedly connected to a support leg 16, and the lower end of the support leg 16 is provided with a groove 17. An electric push rod 18 is fixedly connected inside the groove 17, and the other end of the electric push rod 18 is fixedly connected to a caster wheel 19. The caster wheel 19 and the groove 17 are slidably inserted into each other. By controlling the electric push rod 18, the caster wheel 19 is made to extend out of the groove 17 under the action of the electric push rod 18. Thus, when the caster wheel 19 extends out of the groove 17, it can be moved by the caster wheel 19. When fixing the device, the caster wheel 19 can be moved into the groove 17 so that the support leg 16 contacts the ground. This increases the contact area between the device and the ground when the support leg 16 contacts the ground, thereby achieving a more stable effect.

[0028] refer to Figures 1-4 The fixing component 3 includes a connecting post 32 rotatably connected to the surface of the fixing disk 25. A disk 31 is fixedly connected to the inner side of each connecting post 32. A fixing groove 33 is opened on the inner side of each disk 31. A fixing screw 34 is rotatably connected inside each fixing groove 33. A threaded clamping block 35 is threadedly connected to the outer surface of the fixing screw 34. A driven bevel gear 36 is fixedly connected to the other end of each fixing screw 34. A driving bevel gear 37 is rotatably connected inside the fixing groove 33. The driving bevel gear 37 and the driven bevel gear 36 are meshed with each other.

[0029] refer to Figure 2 The other end of the active bevel gear 37 is fixedly connected to the turntable 13 through the connecting column 32. The outer ring of the bearing 14 is fixedly connected to the outer side of the turntable 13, and the handle 15 is fixedly connected to the inner ring of the bearing 14. By placing the end of the pipe fitting inside the disc 31 of the fixing assembly 3, which is located inside the threaded clamping block 35, and then rotating the turntable 13 to drive the active bevel gear 37 to rotate, the rotation of the active bevel gear 37 can drive the rotation of the driven bevel gear 36 that meshes with it, thereby causing the fixing screw 34 to rotate under the rotation of the driven bevel gear 36. The rotation of the fixing screw 34 can cause the threaded clamping block 35 that is threaded with it to move closer together, thereby fixing the pipe fitting when the threaded clamping block 35 moves closer together.

[0030] Operating principle and advantages: First, by moving the device to a suitable position, the electric push rod 18 is controlled, causing the caster wheel 19 to extend out of the groove 17. This allows for movement via the caster wheel 19. After movement, the caster wheel 19 is moved into the groove 17, bringing the support leg 16 into contact with the ground. This increases the contact area between the device and the ground, further stabilizing the device. Then, the end of the pipe fitting is placed inside the disc 31 of the fixing assembly 3, located on the threaded clamping block 3. Inside 5, the drive bevel gear 37 rotates by rotating the turntable 13. The rotation of the drive bevel gear 37 drives the rotation of the driven bevel gear 36, which in turn drives the fixed screw 34 to rotate. The rotation of the fixed screw 34 causes the threaded clamping block 35, which is threaded to it, to move closer together, thus fixing the pipe fitting. After fixing, the pipe fitting is fixed by the fixing assembly 3. Then, the control motor 26 rotates to drive the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 causes the pipe fitting to rotate. The threaded component 23 moves, causing the fixed disc 25 to move closer together, allowing for pipe fitting assembly. This facilitates subsequent welding. During welding, the dual-axis motor 41 starts, rotating the shaft 43. The rotation of the shaft 43 causes the limiting drive synchronous pulley 44 to rotate. The rotation of the drive synchronous pulley 44, under the action of the synchronous belt 45, causes the driven synchronous pulley 46 to rotate, which in turn causes the fixed assembly 3 to rotate. The rotation of the fixed component 3 allows the pipe to rotate, making welding easier and allowing for convenient adjustment during welding. The connecting rod 9 and the ring 10 connect the threaded part 23 to the active synchronous wheel 44, allowing the active synchronous wheel 44 to move with the fixed component 3 as the threaded part 23 moves. The limiting groove 12 and the limiting block 11 allow the active synchronous wheel 44 to slide on the surface of the shaft 43, and when limited, the active synchronous wheel 44 can rotate with the shaft 43.
