[0021] 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.

[0022] Please see Figure 1-3This utility model provides a technical solution: a welding fixture, including a base 11, a carrier block 9 slidably connected to the top of the base 11, a first slide rail 13 provided on the top of the base 11, a first slider 16 fixedly connected to the bottom of the carrier block 9, and the bottom of the first slider 16 slidably connected to the first slide rail 13. This structure can improve the stability of the carrier block 9 during the sliding process through the first slider 16 and the first slide rail 13. The sliding of the carrier block 9 facilitates the placement of 3C product frame structural components into the interior of the carrier block 9, and also facilitates the removal of the 3C product frame structural components after welding. The carrier block 9 is provided with a longitudinal clamping assembly 10 and a transverse clamping assembly 7. A fixing frame 2 is fixedly connected to one end of the base 11, and a second slide rail 14 is provided on the inner wall of the fixing frame 2. One end of the pressing slider 4 is fixed. A second slider 15 is connected and slidably connected to a second slide rail 14. A limit hole is provided on the lower slider 4. This structure, through the second slide rail 14 and the second slider 15, can improve the stability of the lower slider 4 during lifting and sliding, preventing positional displacement during movement. A positioning spring plunger 3 is threadedly connected to the fixing frame 2. One end of the positioning spring plunger 3 is connected to the limit hole on the lower slider 4. This positioning spring plunger 3, also called a ball plunger or positioning bead / pole, has a spring installed inside the thread. By controlling the screw-in depth, the preload is adjusted and a positioning function is achieved. In this device, it is mainly used to fix the position of the lower slider 4 after lifting and lowering, ensuring the stability of the lower slider 4. The lower slider is lifted and lowered on the fixing frame 2. 4. One end of the lower sliding block 4 is connected to a connecting arm 1. The lower end of the connecting arm 1 is fixedly connected to a base 5. A product pressure head 6 is installed at the bottom of the base 5. A product pressure column 12 is provided at the bottom of the product pressure head 6. The product pressure head 6 is located at the top of the carrier block 9. A product placement surface 8 is provided inside the carrier block 9. The product pressure head 6 and the product pressure column 12 match the structure on the product placement surface 8. The product placement surface 8 of this device can be opened to different depths according to the shape and position of the 3C product frame structure to be welded. The structural shape of the product placement surface 8 is not limited. The longitudinal clamping assembly 10 includes a movable clamping plate 102 that is movably connected to the carrier block 9. A movable push block 103 is fixedly connected to the lower end of the movable clamping plate 102. The movable push block 103 is inserted into one end of the carrier block 9. Block 103 and carrier block 9 form a sliding connection. This structure allows the movable push block 103 to adjust the position of the movable clamping plate 102, facilitating the placement of the 3C product frame structure between the movable clamping plate 102 and the fixed clamping plate 101. A support spring 104 is fixedly connected to the inner wall of the movable clamping plate 102. One end of the support spring 104 is fixedly connected to the inner wall of one end of the carrier block 9. This support spring 104 supports the movable clamping plate 102 in clamping one side of the 3C product frame structure. A fixed clamping plate 101 is fixedly connected to the inner wall of the other end of the carrier block 9. The fixed clamping plate 101 corresponds to the movable clamping plate 102. This structure allows the fixed clamping plate 101 to cooperate with the movable clamping plate 102 to clamp and fix the 3C product frame structure.To ensure the stability of the assembled 3C product frame components, the transverse clamp assembly 7 and the longitudinal clamp assembly 10 have the same structure. The transverse clamp assembly 7 is used to clamp and fix the two sides of the 3C product frame component, while the longitudinal clamp assembly 10 is used to clamp and fix the two ends of the 3C product frame component.

[0023] Working principle: When using this welding fixture, firstly, pull the carrier block 9 out to the rear end, allowing it to slide on the first slide rail 13 via the first slider 16 at the bottom. After removing the carrier block 9, pull the movable push blocks 103 of the transverse clamp assembly 7 and the longitudinal clamp assembly 10 respectively, causing the movable push blocks 103 to slide on the carrier block 9, thus separating the movable clamping plate 102 from the fixed clamping plate 101, exposing the product placement surface 8 on top of the carrier block 9. Then, place the 3C product frame structure components to be welded into the product placement surface 8 on top of the carrier block 9 according to the designated positions. After the 3C product frame structure components are in place, release the movable push blocks 103. The movable push block 103 is clamped onto the outer wall of the 3C product frame structure by the support spring 104, thus fixing the 3C product frame structure. Then, the carrier block 9 is pushed so that it is located at the bottom of the product pressure head 6. Then, the positioning spring plunger 3 is rotated to release it. At this time, the pressing slider 4 can slide down through the second slide rail 14 and the second slider 15. During the descent, the pressing slider 4 drives the connecting arm 1 and the product pressure head 6 to descend, so that the product pressure head 6 and the bottom product pressure column 12 press and fix the 3C product frame structure inside the carrier block 9. Finally, the pressing slider 4 is fixed to the fixing frame 2 by the positioning spring plunger 3, and then the welding work can be carried out.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
