[0002] In the manufacturing process of metal window frames, welding is a key process for connecting window frame profiles. The traditional welding process usually includes steps such as profile cutting, pre-positioning, temporary fixing, and welding. Among these, the positioning accuracy directly affects the dimensional accuracy, geometric tolerances, and overall structural stability of the welded window frame. However, existing technologies still have the following problems, such as: existing mechanical positioning devices are mostly designed for specific window frame sizes or structures, making it difficult to adapt to the processing needs of different specifications (such as irregularly shaped windows). Their flexibility and practicality are poor, which to some extent reduces the welding efficiency of metal window frames. In order to overcome the shortcomings of existing technologies, we propose a welding positioning device for metal window frames. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a welding positioning device for metal window frames, which solves the problem that existing mechanical positioning devices are mostly designed for specific window frame sizes or structures, making it difficult to adapt to the processing needs of different specifications (such as irregularly shaped windows), and their flexibility and practicality are poor, which to some extent reduces the welding efficiency of metal window frames.
[0004] To solve the above technical problems, the present invention provides the following technical solution: a welding positioning device for metal window frames, including a base plate, an irregular clamping component is provided on the upper side of the base plate, and a fixing clamping component is provided on one side of the irregular clamping component;

[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model, through its specially designed clamping assembly including a fixing block, firstly, according to the welding requirements of the metal window frame, rotates a knob to drive the worm gear to rotate. The rotation of the worm gear drives the worm wheel meshing on its outer surface to rotate, thereby driving the positioning plate to rotate to a suitable position. At this time, a section of the window frame is placed on one side of the outer surface of the positioning plate. Then, the telescopic cylinder is activated to push the U-shaped block close to the positioning plate, so that the roller clamps one side of the window frame. Using the above structure, the worm gear rotates to drive the positioning plate to a suitable position, and then the telescopic cylinder is activated to fix the window frame.

[0012] This utility model, through the setting of a fixed clamping assembly, including a mounting bracket, places another section of the metal window frame between two clamping plates. Then, the thumb cylinder is activated to drive the two sliders to slide relative to each other, thereby causing the two clamping plates to clamp the window frame. Next, the electric telescopic rod is activated to drive the mounting bracket to slide on the inner surface of the base plate, causing the clamped end face of the window frame to fit against the end face of the window frame clamped by the irregular clamping assembly. Using the above structure, by activating the thumb cylinder and the electric telescopic rod, not only is the fixed clamping of the window frame achieved, but the position adjustment of the clamped window frame is also realized, further improving the flexibility and practicality of the positioning device.

[0018] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0019] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a welding positioning device for metal window frames, including a base plate 1, an irregular clamping component 2 on the upper side of the base plate 1, and a fixing clamping component 3 on one side of the irregular clamping component 2.
[0020] The irregular clamping assembly 2 includes a fixing block 21. A telescopic cylinder 22 is fixedly installed on one outer surface of the fixing block 21. A U-shaped block 23 is fixedly installed at the telescopic end of the telescopic cylinder 22. An L-shaped rod 24 is rotatably connected to the inner surface of the U-shaped block 23. Rollers 25 are rotatably connected to the inner surfaces of both ends of the L-shaped rod 24. A positioning plate 26 is provided on one side of the L-shaped rod 24. A fixing shaft 27 is fixedly installed on the lower center surface of the positioning plate 26. A worm gear 28 is fixedly installed at the bottom end of the fixing shaft 27. A worm 29 is meshed on the outer surface of the worm gear 28. A knob 211 is fixedly installed at one end of the worm 29.
[0021] Among them, the fixing block 21 is fixedly installed on the upper outer surface of the base plate 1, the positioning plate 26 rotates and slides on the upper outer surface of the base plate 1, and the fixing shaft 27, the worm wheel 28 and the worm 29 are all rotatably connected to the inner wall of one side of the base plate 1.
[0022] After the worm gear 29 rotates and drives the positioning plate 26 to the appropriate position, the telescopic cylinder 22 is activated to fix the window frame, thus realizing the processing needs of window frames of different specifications, greatly improving the flexibility and practicality of the positioning device, and thereby improving the welding efficiency of metal window frames.
[0023] The fixed clamping assembly 3 includes a mounting frame 31. An electric telescopic rod 32 is fixedly mounted on one outer surface of the mounting frame 31. A thumb cylinder 33 is fixedly mounted on the inner surface of the center of the mounting frame 31. Slider blocks 34 are symmetrically mounted on both ends of the thumb cylinder 33. A clamping plate 35 is fixedly mounted on the upper outer surface of the slider 34. The mounting frame 31 slides on the inner surface of the base plate 1. The electric telescopic rod 32 is fixedly mounted on the inner wall of the base plate 1. The slider 34 slides on the inner surface of the mounting frame 31.
[0024] By activating the thumb cylinder 33 and the electric telescopic rod 32, not only is the window frame fixedly clamped, but the position of the clamped window frame is also adjusted, further improving the flexibility and practicality of the positioning device.
[0025] The fixing block 21 and the fixing shaft 27 are set on the same vertical plane, and silicone protective strips are provided on one outer surface of the positioning plate 26 and the clamping plate 35.
[0026] The upper outer surface of the mounting bracket 31 is horizontal with the upper outer surface of the base plate 1, and the clamping plate 35 slides on the upper outer surfaces of the mounting bracket 31 and the base plate 1.
[0027] The working process of this utility model is as follows:
[0028] First, according to the welding requirements of the metal window frame, turn knob 211 to drive worm gear 29 to rotate. The rotation of worm gear 29 drives the worm wheel 28 meshing on its outer surface to rotate, thereby driving positioning plate 26 to rotate to a suitable position. At this time, place one end of the window frame on one side of the outer surface of positioning plate 26. Then, activate telescopic cylinder 22 to push U-shaped block 23 close to positioning plate 26, so that roller 25 clamps one side of the window frame surface. This realizes the processing requirements of window frames of different specifications, greatly improves the flexibility and practicality of positioning device, and thus improves the welding efficiency of metal window frames.
[0029] After the above clamping work is completed, the other part of the metal window frame is placed between the two clamping plates 35. Then, the thumb cylinder 33 is activated to drive the two sliders 34 to slide relative to each other, thereby driving the two clamping plates 35 to clamp the window frame. Then, the electric telescopic rod 32 is activated to drive the mounting bracket 31 to slide on the inner surface of the base plate 1, so that the end face of the clamped window frame is in contact with the end face of the window frame clamped by the irregular clamping component 2. This not only realizes the fixed clamping of the window frame, but also realizes the position adjustment of the clamped window frame. Finally, it is welded by the welding device.
