[0020] 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.

[0021] In the embodiments, by Figure 1-3 A welding clamping device for aluminum alloy door and window production is provided, including a base plate 1, two positioning mechanisms 2 are detachably connected to the top of the base plate 1 by bolts, two clamping bases 3 are detachably connected to the top of the base plate 1, and clamping mechanisms 4 for clamping window frames are provided at the rear ends of the two clamping bases 3.

[0022] The positioning mechanism 2 includes a positioning base 21. The top of the base plate 1 is detachably connected to the positioning base 21 by bolts. The rear end of the positioning base 21 is fixedly connected to a fixing block 22. The inner side of the fixing block 22 is threadedly connected to a screw 23. The top end of the screw 23 is fixedly connected to a positioning rod 24.

[0023] With the above settings, different models of positioning rods 24 are replaced according to the window frame. The screw 23 is rotated to replace the rods. The window frame is placed on two clamping bases 3, so that the positioning rods 24 are inserted into the positioning holes on the window frame (the positioning holes are racetrack-shaped, and the semi-circular radius of the positioning holes is the same as the radius of the positioning rods 24). The horizontal positioning of the window frame is completed. The two clamping bases 3 are moved to the clamping areas on both sides of the window frame. The clamping mechanism 4 applies clamping force from the rear end of the window frame to press the window frame. After clamping, another window frame is clamped by another vertically positioned part of the device. It should be noted that the positioning rods 24 should be slid along the positioning holes of the window frame to align the welding positions of the two parts before clamping and fixing. The positioning mechanism 2 can replace the positioning rods 24 of different specifications with bolts to achieve precise adaptation to different window frames and meet the welding requirements of different specifications of doors and windows. The positioning mechanism 2 and the clamping bases 3 are both connected to the base plate 1 with bolts, which facilitates quick disassembly, maintenance or replacement of worn parts and reduces the cost of use.

[0024] Reference Figure 1-3 The clamping mechanism 4 includes a mounting base 41, the rear end of the clamping base 3 is fixedly connected to the mounting base 41, the rear end of the mounting base 41 is fixedly connected to a cylinder 42, the outer side of the output end of the cylinder 42 is fixedly connected to a connecting arm 43, and the bottom end of the connecting arm 43 is detachably connected to a clamping head 44 by bolts.

[0025] With the above-mentioned structure, the cylinder 42 is activated, and its output end pushes the connecting arm 43 to extend towards the window frame, causing the clamping head 44 to move downward and contact the edge of the window frame. The cylinder 42 continuously applies pressure, and the clamping head 44 applies a vertically downward clamping force to the window frame, pressing the window frame tightly against the top of the clamping base 3. After welding is completed, the cylinder 42 retracts, causing the clamping head 44 to rise and detach from the window frame, allowing the operator to safely remove the finished product.

[0026] Reference Figure 1-3 The top of the positioning rod 24 is provided with a smooth tip 5;

[0027] With the above structural design, when the smooth tip 5 contacts the window frame, there are no sharp edges, which can effectively reduce the scratching of the aluminum alloy window frame surface by the positioning rod 24, protect the integrity of the coating or oxide film of the window frame, and avoid appearance damage caused by hard contact.

[0028] Reference Figure 1-3 Among them, a protective sticker 6 is affixed to the bottom of the clamping head 44;

[0029] With the above structural design, the protective sticker 6 is made of flexible material (such as rubber or silicone). When the clamping head 44 is pressed down, it contacts the window frame through the protective sticker 6, avoiding the clamping head 44 from directly scratching the surface of the window frame, preventing damage to the coating or oxide layer of the aluminum alloy profile, and ensuring the appearance quality of the finished product.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
