Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture for a high-frequency pipe welding machine. Background Technology

[0002] A high-frequency welded pipe machine is a pipe production equipment. Through the relevant components of the welding machine, a plate can be bent into a pipe shape, and then the splicing points are welded by a high-frequency welding machine to produce the pipe. After welding, the pipe is clamped by a welding fixture.

[0003] According to the publication number (CN220161495U), a welding fixture for a high-frequency welded pipe machine is disclosed, which includes a bracket and two sets of arc-shaped clamping plates. Each set of arc-shaped clamping plates has a mounting block fixedly installed on one side. It also includes: a clamping component that can avoid excessive compression of the welded pipe, and the clamping component is set on the bracket; and an adsorption component for adsorbing and fixing the welded pipe, and the adsorption component is installed on the bracket.

[0004] The implementation of this technical solution has at least the following drawbacks: although the utility model can clamp and position the pipe, it is inconvenient to smoothly push the pipe after welding, which affects the welding efficiency of the workers and urgently needs to be improved. Therefore, we propose a welding fixture for a high-frequency pipe welding machine. Utility Model Content

[0005] The purpose of this utility model is to provide a welding fixture for a high-frequency pipe welding machine, which solves the problem mentioned in the background art that it is inconvenient to smoothly push the pipe after welding, thus affecting the welding efficiency of the workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for a high-frequency welded pipe machine, comprising a first limiting plate, a plurality of balls being rotatably mounted on the upper end of the first limiting plate, a second limiting plate being provided on the upper end of the first limiting plate, a first hydraulic cylinder being fixedly mounted on both sides of the first limiting plate, a steel ball being movably mounted in the middle of the second limiting plate, a second hydraulic cylinder being fixedly mounted on both sides of the upper end of the second limiting plate, a fixed plate being mounted on the output end of the second hydraulic cylinder, and a ball rod being fixedly mounted in the middle of the lower end of the fixed plate;

[0007] The second limiting plate has strip grooves on both sides, and a rubber block is provided in the inner cavity of the strip groove. A slider is fixedly installed on the upper end of the rubber block. A sliding groove is provided on the inner wall of the strip groove. A first airbag is bonded to the upper end of the inner cavity of the strip groove. A second airbag is bonded to the upper end of the fixing plate. A fixing frame is welded to the upper end of the second limiting plate.

[0008] By adopting the above technical solution, the steel ball can be pushed into the second limiting plate. During the upward movement of the fixed plate, the fixed plate, together with the fixed frame, compresses the second airbag. The air in the second airbag is discharged into the first airbag through the hose. The first airbag pushes the rubber block in the strip groove downward. With the downward movement of the second limiting plate, the rubber block is pressed against the surface of the pipe, thereby limiting the position of the pipe and facilitating welding operations. After welding, the ball rod can push the steel ball. At the same time, due to the spring's elasticity, the spring drives the rubber block into the strip groove, thereby making the steel ball and ball bearings contact the surface of the pipe. This facilitates smooth pushing of the pipe after welding and improves the welding efficiency of the workers.

[0009] Optionally, the air inlet of the first airbag is connected to a hose, and the other end of the hose is connected to the air outlet of the second airbag.

[0010] By adopting the above technical solution and using the hose, the air inside the second airbag can be guided.

[0011] Optionally, the size of the rubber block is adapted to the size of the strip groove, and the rubber block is movably connected to the strip groove.

[0012] By adopting the above technical solution and setting rubber blocks, the pipe can be contacted and tightened, thereby limiting the position of the pipe.

[0013] Optionally, the output end of the first hydraulic cylinder is fixedly connected to one side of the second limiting plate.

[0014] By adopting the above technical solution and by setting the first hydraulic cylinder, the second limit plate can be moved.

[0015] Optionally, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0016] By adopting the above technical solution, the stability of the rubber block movement can be guaranteed through the cooperation of the slider and the groove.

[0017] Optionally, a spring is fixedly installed in the inner cavity of the slide, and the other end of the spring is fixedly connected to the slider.

[0018] By adopting the above technical solution and using the spring, the rubber block can be reset and retracted into the strip groove.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] The technical solution of this application, through the setting of a first limiting plate, a second limiting plate, a steel ball, a ball rod, a rubber block, a hose, a second airbag, and a fixing frame, allows the steel ball to be pushed into the second limiting plate. During the upward movement of the fixing plate, the fixing plate, in conjunction with the fixing frame, compresses the second airbag, causing air from the second airbag to be discharged into the first airbag through the hose. The first airbag pushes the rubber block in the strip groove downwards, and with the downward movement of the second limiting plate, the rubber block presses against the surface of the pipe, thus limiting the position of the pipe and facilitating welding operations. After welding, the ball rod can push the steel ball, and simultaneously, due to the spring's elasticity, the spring pulls the rubber block back into the strip groove, allowing the steel ball and ball bearings to contact the pipe surface. This facilitates smooth pushing of the pipe after welding, improving welding efficiency. Attached Figure Description

[0026] Please see Figure 1-3 This utility model provides a technical solution: a welding fixture for a high-frequency welded pipe machine, including a first limiting plate 1, a plurality of balls 11 are rotatably mounted on the upper end of the first limiting plate 1, a second limiting plate 12 is provided on the upper end of the first limiting plate 1, a first hydraulic cylinder 2 is fixedly mounted on both sides of the first limiting plate 1, a steel ball 21 is movably mounted in the middle of the second limiting plate 12, a second hydraulic cylinder 22 is fixedly mounted on both sides of the upper end of the second limiting plate 12, a fixed plate 23 is mounted on the output end of the second hydraulic cylinder 22, and a ball rod 24 is fixedly mounted in the middle of the lower end of the fixed plate 23;

[0027] The second limiting plate 12 has strip grooves 31 on both sides. A rubber block 3 is installed in the inner cavity of the strip groove 31. A slider 34 is fixedly installed on the upper end of the rubber block 3. A sliding groove 33 is opened in the inner wall of the strip groove 31. A first airbag 32 is bonded to the upper end of the inner cavity of the strip groove 31. A second airbag 5 is bonded to the upper end of the fixing plate 23. A fixing frame 6 is welded to the upper end of the second limiting plate 12. The output end of the first hydraulic cylinder 2 is fixedly connected to one side of the second limiting plate 12. The first hydraulic cylinder 2 can drive the second limiting plate 12 to move. The size of the slider 34 is adapted to the size of the sliding groove 33, and the slider 34 and the sliding groove 33 are slidably connected. The movement of the rubber block 3 is ensured by the cooperation of the slider 34 and the sliding groove 33. A spring 35 is fixedly installed in the inner cavity of the sliding groove 33. The other end of the spring 35 is fixedly connected to the slider 34. The spring 35 can drive the rubber block 3 to reset and enter the strip groove 31.

[0028] The air inlet of the first airbag 32 is connected to a hose 4, and the other end of the hose 4 is connected to the air outlet of the second airbag 5. The hose 4 is used to guide the air inside the second airbag 5.

[0029] The size of the rubber block 3 is adapted to the size of the strip groove 31, and the rubber block 3 is movably connected to the strip groove 31. By setting the rubber block 3, the pipe can be contacted and tightened, thereby limiting the position of the pipe.

[0030] During welding, the pipe is first placed on the first limiting plate 1. Then, the second hydraulic cylinder 22 is opened, which moves the fixing plate 23 upward. The fixing plate 23 moves the ball rod 24 upward. At the same time, the first hydraulic cylinder 2 is opened, which moves the second limiting plate 12 downward. As the steel ball 21 loses the pressure of the ball rod 24, it is pushed into the second limiting plate 12. During the upward movement of the fixing plate 23, the fixing plate 23, together with the fixing frame 6, compresses the second airbag 5. The air in the second airbag 5 is discharged into the first airbag 32 through the hose 4. Inside, the first airbag 32 pushes the rubber block 3 in the strip groove 31 downwards, and together with the downward-moving second limiting plate 12, the rubber block 3 abuts against the surface of the pipe, thereby limiting the position of the pipe and facilitating the welding operation. After welding is completed, the second hydraulic cylinder 22 is controlled to reset, thereby pushing the ball rod 24 against the steel ball 21. At the same time, due to the elasticity of the spring 35, the spring 35 drives the rubber block 3 into the strip groove 31, thereby making the steel ball 21 and the ball bearing 11 contact the surface of the pipe, thus facilitating the smooth pushing of the pipe after welding and improving the welding efficiency of the workers.
