Technical Field

[0001] The utility model belongs to the technical field of welding, in particular to an anti-rotation component for round pipe welding. Background Art

[0002] Laser welding is a high-energy beam welding method with high energy density and fast welding speed. However, if the round tube rotates during the welding process, the welding quality will be unstable and even welding defects will occur. Therefore, in order to ensure the welding quality, anti-rotation measures need to be taken during the round tube laser welding process.

[0003] In the prior art, the round tube is often placed in a clamp, and the clamp is clamped by rotating the screw to prevent the round tube from rotating during the welding process. However, the screw often requires manpower to rotate in circles, which makes the use of the clamp more troublesome and the anti-rotation operation of the round tube more inconvenient. An anti-rotation component for round tube welding is now proposed to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model makes the device easy to use by coordinating the structures of a push rod, a spring, a swivel, a telescopic rod, a slider and a connecting rod.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3As shown, the utility model provides an anti-rotation assembly for round tube welding, including a base 1, two support platforms 2 are fixedly connected to the top of the base 1, a suction hole 3 is opened in a linear array in the middle of the support platform 2, a push rod 4 is movably connected to the middle of the base 1, one end of the push rod 4 is elastically connected to one end of a spring 5, the outer circumference of the push rod 4 is rotatably connected to two swivels 6, the outer circumference of the swivel 6 is fixedly connected to one end of a telescopic rod 7, the other end of the telescopic rod 7 is fixedly connected to one side of a slider 8, the other side of the slider 8 is fixedly connected to one end of a connecting rod 9, the other end of the connecting rod 9 is slidably connected to a piston plate 10, the outer side of the slider 8 is slidably connected to a limiting slide rail 11, and the side of the base 1 away from the spring 5 is fixedly connected to a limiting frame 12;

[0021] By placing the round tube to be welded in the middle of the support platform 2 and pressing the push rod 4 to make the spring 5 contract, the push rod 4 drives the swivel 6 to move, and the swivel 6 drives the slider 8 to move through the telescopic rod 7. The slider 8 moves along the limiting slide rail 11, so that the telescopic rod 7 is gradually shortened, and the slider 8 drives the piston plate 10 to move downward through the connecting rod 9, so that negative pressure is generated above the piston plate 10, and the surface of the round tube can be tightly adsorbed and limited through the suction hole 3. When the push rod 4 is fully pressed, the push rod 4 is rotated again to make the push rod 4 engage with the limiting frame 12, so that the device is easy to operate, can quickly limit the round tube to be welded, and can effectively prevent the round tube from rotating during welding.

[0022] like Figure 1 and Figure 3 As shown, the push rod 4 and the limit frame 12 are both L-shaped structures, the other end of the spring 5 is fixedly connected to the base 1, and the limit frame 12 and the push rod 4 are staggered from each other. When the push rod 4 squeezes the spring 5 to contract, the push rod 4 rotates to engage with the limit frame 12;

[0023] When the push rod 4 is fully pressed, the push rod 4 is rotated again so that the push rod 4 is engaged with the limit frame 12, and then welding is performed. This can quickly release manpower and prevent the elastic force of the spring 5 from pushing the push rod 4 back to its original position. When welding is completed, the push rod 4 is rotated in the opposite direction so that the push rod 4 is not engaged with the limit frame 12. The elastic force of the spring 5 can push the push rod 4 out and return it to its original position, thereby releasing the device's adsorption of the round tube, making it easier to remove the round tube.

[0024] like Figures 2 to 4 As shown, the outer side of the swivel 6 is movably connected to the inside of the base 1, the outer side of the piston plate 10 is sealed and movably connected to the base 1, the limiting slide rail 11 is arranged to be tilted downward from left to right, the outer side of the limiting slide rail 11 is fixedly connected to the base 1, the suction hole 3 is arranged directly above the piston plate 10, the middle part of the support platform 2 is an arc structure, the surface of the arc structure is made of rubber material, there is a gap between the two support platforms 2, and the bottom side of the piston plate 10 is provided with a slide groove for limiting the sliding of the connecting rod 9;

[0025] By pressing the push rod 4, the spring 5 contracts, the push rod 4 drives the swivel 6 to move, the swivel 6 drives the slider 8 to move through the telescopic rod 7, the slider 8 moves along the limiting slide rail 11, so that the telescopic rod 7 is gradually shortened, and the slider 8 drives the piston plate 10 to move downward through the connecting rod 9, so that negative pressure is generated above the piston plate 10, and the surface of the circular tube can be tightly adsorbed and limited through the suction hole 3, thereby achieving the effect of preventing the circular tube from rotating.

[0026] The working principle and use process of this utility model:

[0027] First, the operator places the round tube to be welded in the middle of the support platform 2 so that the welding position is located in the interval between the two support platforms 2. By pressing the push rod 4, the spring 5 contracts, and the push rod 4 drives the swivel 6 to move. The swivel 6 drives the slider 8 to move through the telescopic rod 7. The slider 8 moves along the limit slide rail 11, so that the telescopic rod 7 is gradually shortened. The slider 8 drives the piston plate 10 to move downward through the connecting rod 9, so that negative pressure is generated above the piston plate 10, and the surface of the round tube can be tightly adsorbed and limited through the suction hole 3. When the push rod 4 is fully pressed, the push rod 4 is rotated again to make the push rod 4 engage with the limit frame 12 to complete the operation.
