However, when the position of the check valve needs to be adjusted, it must be manually removed and re-clamped. This method not only increases the labor intensity of workers but also reduces the welding speed of check valves. Therefore, we provide a welding device for check valve processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] In the prior art, there is a technical problem that it is not easy to adjust the position of the fixed check valve during the welding process. This embodiment provides a welding device for check valve processing. Please refer to... Figures 1-5 This welding device for check valve processing can quickly adjust the position and angle of a fixed check valve, improving the welding speed. It includes a welding table 2 mounted on the top of a base 1, a welding mechanism 3 for eliminating welding fumes at the top of the base 1, and an adjustment mechanism 4 for adjusting the clamping position on the welding table 2. The welding mechanism 3 can adjust the welding position within a certain range and eliminate welding fumes. The adjustment mechanism 4 can stably clamp the check valve and adjust its position and angle, improving the welding efficiency of the check valve.

[0026] To quickly adjust the position and angle of the fixed check valve during the welding process and improve the welding speed, the adjustment mechanism 4 includes a connecting seat 41 mounted on the welding table 2. A base 42 is fixedly mounted on the top of the connecting seat 41. A first adjusting rod 43 is rotatably connected to the base 42. The first adjusting rod 43 and the base 42, as well as the second adjusting rod 44 and the first adjusting rod 43, are all connected by fastening rods 45. This allows for quick adjustment of the position of the fixed check valve, improving the welding speed. A second adjusting rod 44 is rotatably connected to the top of the first adjusting rod 43. A fastening rod 45 is connected to the second adjusting rod 44. A rotary motor 46 is fixedly mounted on the top of the second adjusting rod 44. A fixing component 401 is provided above the welding table 2 to stably fix the check valve. By adjusting the connection angle between the first adjusting rod 43 and the chassis 42, and the connection angle between the second adjusting rod 44 and the first adjusting rod 43, and by fixing the first adjusting rod 43 and the second adjusting rod 44 with the adjusted connection angle by the fastening rod 45, and under the operation of the rotary motor 46, the angle of the fixed check valve can be adjusted, thereby improving the welding speed of the check valve.

[0027] In the process of welding the check valve, in order to fix the check valve, improve the stability of the welding, and enhance the welding quality, the fixing component 401 includes a clamping frame 47 installed at the output end of the rotary motor 46. A drive motor 48 is installed on the clamping frame 47. Two sets of meshing toothed rods 49 are rotatably connected inside the clamping frame 47, and one set of toothed rods 49 is connected to the output end of the drive motor 48. The other end of the toothed rod 49 is rotatably connected to a clamping claw 410. The inner side of the clamping claw 410 is provided with an arc groove, which facilitates the fitting of the arc groove with the check valve shell and improves the clamping efficiency. A support rod 411 is rotatably connected to the clamping claw 410 and rotatably connected to the inside of the clamping frame 47. The support rods 411 are symmetrically distributed on both sides inside the clamping frame 47 and play a supporting role, so that the clamping claw 410 can clamp the check valve more stably. The operation of the drive motor 48 drives a set of racks 49 to rotate. Since the two sets of racks 49 mesh with each other, the two sets of clamping claws 410 can stably clamp the check valve under the rotational support of the support rod 411, thus improving the stability of the welding.

[0028] Example 2

[0029] Based on Example 1, such as Figures 1-5 As shown, based on the current problem that it is not easy to adjust the position of the fixed check valve during the welding process, and because welding the check valve will produce a certain amount of welding fumes, which can easily affect the welding environment when they are dispersed in the air, this device is also equipped with a welding structure that can eliminate welding fumes and improve the welding environment.

[0030] In the process of welding check valves, in order to quickly adjust the welding position according to specific needs and thus improve welding efficiency, the welding mechanism 3 includes a fixed frame 31 slidably connected to the inside of the top of the base 1. The fixed frame 31 has a groove 32, and a slider 33 is slidably connected inside the groove 32. A pull rod 34 is fixedly installed on the side of the slider 33, and a mounting plate 35 is fixedly installed on the slider 33. An electric push rod 36 is fixedly installed on the side of the mounting plate 35, and a welding head 37 is installed on the electric push rod 36. A fume extraction component 301 capable of absorbing welding fumes is provided on the mounting plate 35. By pushing the fixed frame 31 to slide inside the top of the base 1, the longitudinal position of the welding head 37 can be changed. And by pulling the pull rod 34, the slider 33 slides inside the groove 32, thereby adjusting the lateral position of the welding head 37, thus enabling rapid adjustment of the welding position.

[0031] To eliminate welding fumes and improve the welding environment, the fume extraction assembly 301 includes a top plate 38 mounted on the top of the mounting plate 35. A fume extraction hood 39 is installed inside the top plate 38, and a connecting pipe 310 is connected to the extraction end of a fume extraction device. Through the operation of the fume extraction device and the connection via the connecting pipe 310, the fume extraction hood 39 absorbs the welding fumes, preventing them from dispersing into the air and affecting the welding environment.
