[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: a positioning and clamping mechanism for door and window welding, including a base 1, a placing shell 3 is fixedly connected to the top of the base 1, a motor 4 is fixedly connected to the bottom of the base 1, the output end of the motor 4 is fixedly connected to a turntable 5, both sides of the top of the turntable 5 are rotatably connected to connecting rods 6, one end of the connecting rod 6 is rotatably connected to a moving plate 7, two fixed blocks 8 are fixedly connected to the top of the moving plate 7, a clamping plate 9 is fixedly connected to the top of the fixed block 8, rubber blocks 10 are fixedly connected to the corresponding sides of the two clamping plates 9, two slide grooves 12 are opened at the top of the placing shell 3, the shapes of the fixed blocks 8 and the slide grooves 12 match, the outer sides of the four fixed blocks 8 are respectively slidably connected to the inner walls of the corresponding slide grooves 12, two slide bars 11 are slidably connected to the through holes of the moving plate 7, both ends of the two slide bars 11 are fixedly connected to the inner wall of the placing shell 3, and support legs 2 are fixedly connected to the four corners of the bottom of the base 1.

[0033] Specifically, the supporting leg 2 provides stable support to ensure that the entire mechanism does not shake during the welding process, guaranteeing the accuracy and quality of welding. The sliding rod 11 provides precise guidance for the horizontal movement of the moving plate 7, ensuring that the clamping plate 9 can accurately clamp the doors and windows, improving the accuracy and reliability of clamping. The rubber block 10 increases the friction with the doors and windows, improves the stability of clamping, and prevents the doors and windows from sliding or shifting during the welding process. It plays a buffering role to avoid direct hard contact between the clamping plate 9 and the doors and windows, protecting the surface of the doors and windows from damage. After the motor 4 is started, its output end drives the turntable 5 to rotate. The connecting rod 6 on the turntable 5 changes its angle as the turntable 5 rotates. Since one end of the connecting rod 6 is rotatably connected to the moving plate 7, the moving plate 7 moves horizontally along the sliding rod 11 under the drive of the connecting rod 6. The fixed block 8 on the top of the moving plate 7 slides in the chute 12 on the top of the placement shell 3, thereby driving the clamping plates 9 to approach or move away from each other. When the clamping plates 9 approach each other, the rubber block 10 contacts the doors and windows, and the doors and windows are clamped and fixed on the placement shell 3 through friction and pressure.

[0034] Referring to Figure 1 , Figure 2 and Figure 5 , an installation frame 13 is installed at the rear side of the top of the base 1. A cylinder 14 is fixedly connected to the top of the installation frame 13. The output end of the cylinder 14 is fixedly connected to a connecting plate 15. An auxiliary component is arranged on the outer side of the connecting plate 15. The auxiliary component is used to assist in the positioning of the doors and windows. The auxiliary component includes a plurality of pressing shells 16. The outer sides of the plurality of pressing shells 16 are evenly distributed on the outer side of the connecting plate 15. A pressing plate 19 is arranged inside the pressing shell 16. A guide plate 27 is fixedly connected to the top of the pressing plate 19. A plurality of card slots 20 are formed on the outer side of the pressing plate 19. A pressing groove 17 is formed inside the pressing shell 16. A guide groove 18 is formed on the inner side wall of the pressing groove 17. A connecting groove 21 is formed on the outer side of the pressing shell 16. The outer sides of the plurality of pressing plates 19 are respectively slidably connected to the inner walls of the corresponding pressing grooves 17. The outer sides of the plurality of guide plates 27 are respectively slidably connected to the inner walls of the corresponding guide grooves 18.

[0035] Specifically, the mounting bracket 13 provides a stable mounting foundation for the cylinder 14, ensuring that the cylinder 14 does not shake or displace during operation. The pressing shell 16 provides a space for mounting and protecting the pressing plate 19. During the welding process, the pressing shell 16 can prevent external factors from interfering with the pressing plate 19, ensuring that the pressing plate 19 can stably position the doors and windows. By sliding within the pressing groove 17, the pressing plate 19 can adjust its protruding length according to the actual situation of the doors and windows, thus better adapting to doors and windows of different thicknesses. The design of multiple card slots 20 enables the pressing plate 19 to be fixed at different positions, improving the flexibility of positioning. The cooperation between the guiding plate 27 and the guiding groove 18 ensures the stability and directionality of the pressing plate 19 during movement. The guiding plate 27 slides within the guiding groove 18, restricting the movement direction of the pressing plate 19. The connecting groove 21 provides a passage for the clamping rod 24, enabling the clamping rod 24 to slide between the pressing shell 16 and the pressing plate 19. When the clamping rod 24 is inserted into the card slot 20, it can fix the pressing plate 19 at a specific position, ensuring that the pressing plate 19 does not move accidentally during the welding process and improving the reliability of positioning.

[0036] Referring to Figure 1 , Figure 5 and Figure 6 , a fixed shell 22 is fixedly connected to the outer side of each of the multiple pressing shells 16. An activity plate 23 is slidably connected to the inner wall of the fixed shell 22. One end of the activity plate 23 is fixedly connected to a clamping rod 24, and the other end of the activity plate 23 is fixedly connected to a pull rod 25. A spring 26 is sleeved on the outer side of the pull rod 25. The shapes of the multiple clamping rods 24 respectively match those of the card slots 20 and the connecting grooves 21. The outer sides of the multiple clamping rods 24 are respectively slidably connected to the inner walls of the corresponding connecting grooves 21. One end of each of the multiple clamping rods 24 is respectively inserted and matched with the inner wall of the corresponding card slot 20. One end of each of the multiple springs 26 is respectively fixedly connected to one end of the corresponding activity plate 23, and the other end of each of the multiple springs 26 is respectively fixedly connected to the inner wall of the corresponding fixed shell 22.

[0037] Specifically, the fixed housing 22 provides a stable sliding track for the movable plate 23, ensuring that the movable plate 23 can move smoothly during the process of pulling the pull rod 25 and the spring 26 rebounding. In the natural state of the spring 26, the elastic force of the spring 26 pushes the movable plate 23 so that the locking rod 24 is inserted into the card slot 20, ensuring that the pressing plate 19 can maintain a fixed state when the length does not need to be adjusted, and providing a stable auxiliary positioning pressure for the doors and windows. When it is necessary to adjust the length of the pressing plate 19 to adapt to doors and windows of different sizes, pull the pull rod 25 outwards. The pull rod 25 drives the movable plate 23 to slide in the fixed housing 22, and the movable plate 23 moves away from the pressing housing 16 against the elastic force of the spring 26. As the movable plate 23 moves, the locking rod 24 fixed at one end of the movable plate 23 also slides in the connecting slot 21 and gradually disengages from the card slot 20 of the pressing plate 19. At this time, the pressing plate 19 is no longer fixed and can slide in the pressing slot 17 to adjust the extended length. After the pressing plate 19 is adjusted to the required length, release the pull rod 25, and the spring 26 pushes the movable plate 23 towards the pressing housing 16 under the action of its own elastic force. The locking rod 24 slides in the connecting slot 21 again and is inserted into the corresponding card slot 20 on the pressing plate 19 to fix the pressing plate 19 in the new position.

[0038] Working principle: First, place the doors and windows to be welded at a suitable position on the placement shell 3, and then start the motor 4. The motor 4 drives the turntable 5 to rotate. The connecting rod 6 on the turntable 5 moves as the turntable 5 rotates, and under the restriction of the sliding rod 11, the connecting rod 6 drives the moving plate 7 to move horizontally. The movement of the moving plate 7 drives the fixed block 8 to slide in the sliding groove 12, thereby making the clamping plates 9 approach or move away from each other. When the clamping plates 9 approach each other, the rubber block 10 contacts the doors and windows, and the doors and windows are clamped and fixed on the placement shell 3 through friction and pressure. By starting the cylinder 14, the output end of the cylinder 14 pushes the connecting plate 15 downward, so that multiple pressing shells 16 on the outside of the connecting plate 15 move downward and approach the doors and windows. When the pressing plate 19 on the pressing shell 16 contacts the doors and windows, it performs auxiliary positioning on the doors and windows to ensure the stability of the doors and windows during the welding process. By pulling the pull rod 25 outwards. The pull rod 5 drives the movable plate 23 to slide in the fixed shell 22, and the movable plate 23 moves in a direction away from the pressing shell 16 against the elastic force of the spring 26. As the movable plate 23 moves, the clamping rod 4 fixed at one end of the movable plate 23 also slides in the connecting groove 21 and gradually disengages from the clamping groove 20 of the pressing plate 19. After the clamping rod 24 disengages from the clamping groove 20, the pressing plate 19 is no longer fixed and can slide left and right in the pressing groove 17. At this time, adjust the length of the pressing plate 19 extending out of the pressing shell 16 as needed. The guide plate 27 slides in the guide groove 18. When the pressing plate 19 is adjusted to the required length, release the pull rod 25. The spring 26 pushes the movable plate 23 in a direction close to the pressing shell 16 under the action of its own elastic force, and the clamping rod 24 slides in the connecting groove 21 again and inserts into the corresponding clamping groove 20 on the pressing plate 19 to fix the pressing plate 19 in a new position. The adjustment of the length of the pressing plate 19 is realized, so that the auxiliary component can better adapt to doors and windows of different sizes and provide more accurate auxiliary positioning for the welding of doors and windows.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
