[0023] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the welding clamping unit proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0024] See Figures 1-4 The welding clamping unit provided by this utility model includes: a welding machine base 1, with two sets of angle adjustment mechanisms 2 symmetrically arranged on the top of the welding machine base 1, and each set of angle adjustment mechanisms 2 is equipped with a clamping mechanism 3 symmetrically arranged. Both clamping mechanisms 3 are used to clamp and fix parts. The angle adjustment mechanisms 2 are used to adjust the tilt angle of the clamped and fixed parts. The angle adjustment mechanism 2 includes a motor 21, a swing arm 22, a connecting seat 23, and an electric telescopic rod 24. The motor 21 is fixedly installed on the top of the welding machine base 1, and the swing arm 22 is fixedly installed on the output shaft end of the motor 21. The swing arm 22 is tilted. The connecting seat 23 is fixedly installed on the top front side of the swing arm 22. The connecting seat 23 has a hollow structure, which reduces the weight of the connecting seat 23 while ensuring structural strength, which helps to reduce energy consumption during equipment operation. The electric telescopic rod 24 is fixedly installed on the front side of the connecting seat 23. The swing arm 22 is driven to rotate by the motor 21. With the electric telescopic rod 24, the tilt angle of the clamped and fixed parts can be easily adjusted. This design eliminates the need for complicated manual operation to adjust or change tooling when welding parts with different angle requirements, greatly improving the flexibility and efficiency of welding work. It should be noted that the motor 21 is a reversible motor.

[0025] In this embodiment, the clamping mechanism 3 includes a mounting plate 31, a bearing seat 32, a top plate 33, an electric telescopic rod 24, and a clamping seat 35. The mounting plate 31 is fixedly installed on the output shaft end of the electric telescopic rod 24. The bearing seat 32 is fixedly installed on the bottom side of the mounting plate 31. The top plate 33 is fixedly installed on the top of the mounting plate 31. The electric telescopic rod 24 is fixedly installed on the top of the top plate 33. The clamping seat 35 is fixedly installed on the output shaft end of the electric telescopic rod 24 and located directly above the bearing seat 32. The top of the bearing seat 32 and the bottom of the clamping seat 35 are both provided with triangular grooves 36. The electric telescopic rod 24 can be used to control the linear movement of the clamping seat 35, thereby adjusting the distance between the bearing seat 32 and the clamping seat 35. By using the cooperation of the bearing seat 32 and the clamping seat 35, the parts to be welded can be effectively clamped and fixed. The design of the triangular grooves 36 can better adapt to parts of different shapes, providing accurate positioning and stable clamping effect.

[0026] In this embodiment, a clearance hole is provided at the top of the top plate 33, and the output shaft end of the electric telescopic rod 34 passes through the clearance hole to ensure that the output end of the electric telescopic rod 34 can extend and retract smoothly.

[0027] In this embodiment, both the top surface of the bearing seat 32 and the bottom surface of the clamping seat 35 are provided with anti-slip textures. The anti-slip texture design further enhances the friction when the parts are clamped, preventing the parts from sliding during clamping.

[0028] In this embodiment, a limit stop bar 4 is fixedly installed on the top of the welding machine 1. The top end of the limit stop bar 4 abuts against the swing arm 22, which can effectively limit the rotation angle range of the swing arm 22. When the top end of the limit stop bar 4 abuts against the swing arm 22, the bearing seat 32 and the clamping seat 35 are in a horizontal state, so as to meet the requirement of precise flat welding of the two parts.

[0029] In this embodiment, a vertical plate 5 is fixedly installed on the top rear side of the welding machine 1. An arc-shaped guide groove 6 is provided on the front side wall of the vertical plate 5. A guide rod 25 is fixedly installed on the rear side wall of the connecting seat 23. The rear end of the guide rod 25 is slidably installed in the arc-shaped guide groove 6. The arc center of the arc-shaped guide groove 6 coincides with the axis of the output shaft of the motor 21, so that the connecting seat 23 moves more smoothly and accurately when the motor 21 drives the swing arm 22 to rotate, further ensuring the accuracy of the part angle adjustment.

[0030] In this embodiment, a welding rod storage box 7 with an open top is fixedly installed on the front side wall of the vertical plate 5. Multiple evenly distributed hooks 8 are fixedly installed on the front side wall of the vertical plate 5. The welding rod storage box 7 provides convenience for storing welding rods, and the multiple hooks 8 provide convenience for hanging and placing tools required during welding (such as welding pliers, slag hammers, angle grinders, etc.), making it convenient for operators to access them at any time during the welding process, improving work efficiency, and also making the work area more tidy and orderly, which is conducive to improving the safety of the working environment.

[0031] The working principle of the welding clamping unit provided by this utility model:

[0032] Before welding the two parts, place them on their respective support seats 32, with the parts to be welded facing each other. Then, activate the two electric telescopic rods 34 to extend. The output shaft of the electric telescopic rods 34 drives the clamping seat 35 to move downward. The clamping seat 35 can then press and fix the parts on the support seats 32. At the same time, the anti-slip texture on the surface of the support seats 32 and the clamping seat 35 increases the friction between the parts and further prevents the parts from sliding during the clamping process, ensuring that the parts maintain a stable position during subsequent welding. A triangular groove 36 is also provided to facilitate the placement and clamping of cylindrical or other shaped parts, thus better adapting to parts of various shapes.

[0033] After the parts are pressed and fixed, by controlling the extension of the two electric telescopic rods 24, the corresponding mounting plates 31 can be pushed to move horizontally and linearly, so that the two pressed and fixed parts gradually move closer to each other until the parts to be welded are tightly in contact. Then, stop the operation of the two electric telescopic rods 24, and the welding gun can be used to weld the two parts. This welding process is flat welding.

[0034] After the parts are clamped and fixed according to the above steps, when it is necessary to perform a certain angled welding on the two parts, control the operation of the two motors 21 respectively. The output shaft of the motor 21 drives the swing arm 22 to rotate. When the swing arm 22 rotates, it will drive the connecting seat 23, the electric telescopic rod 24, the clamping mechanism 3 and the clamped and fixed parts to rotate around the output shaft of the motor 21. This will adjust the two clamped and fixed parts to the required tilt angle. By controlling the extension and retraction of the two electric telescopic rods 24 respectively, the position of the two parts can be adjusted so that the parts of the two parts that need to be welded are tightly in contact. Then, the welding gun can be used to weld the two parts. This welding process is called oblique welding.

[0035] After the welding work is completed, the two electric telescopic rods 34 can be controlled to retract and reset, driving the two clamping seats 35 back to their original positions, and the welded parts can be removed.

[0036] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0037] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
