[0026] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] As described in the background art, the welding fixture in the above patent requires additional tools to lift the parts when in use because the automobile parts and chassis are heavy, so that the clamping frame is aligned with the edge of the part, which makes it more troublesome to use.

[0028] In order to solve this technical problem, the utility model provides an automobile welding fixture, which is used for precise welding of automobile parts.

[0029] Specifically, please refer to Figure 1-Figure 5 , the automobile welding fixture specifically includes:

[0030] Platform 1, support frame 2, adjustment mechanism 3 and fixing mechanism 4. The support frame 2 is fixedly connected to the bottom of the platform 1. The adjustment mechanism 3 for adjusting the position of the automobile part during welding is set above the platform 1. The number of adjustment mechanisms 3 is symmetrical and they are set at the two ends of the platform 1. The fixing mechanism 4 for fixing the automobile part is set on the outside of the adjustment mechanism 3.

[0031] The adjustment mechanism 3 includes a placement rack 5, a connecting rack 6, a flip assembly, and a buffer assembly. The placement rack 5 is arranged above the platform 1, and the connecting rack 6 is fixedly connected to the upper middle part of the platform 1. One end of the placement rack 5 is rotatably connected to the platform 1 through the connecting rack 6.

[0032] The automobile welding fixture provided by the present invention has a structural design at the adjustment mechanism 3, so that when in use, the automobile component can be directly placed on any placement rack 5. At this time, the first electric telescopic rod 7 can be started to drive the placement rack 5 to gradually rise, changing the welding angle of the device, making the welding effect more accurate. The two first electric telescopic rods 7 can also be started at the same time to make the two placement racks 5 clamp the two sides of the component. Then, the placement rack 5 corresponding to the unwelded side can be lowered to achieve the flipping of the component, which effectively improves the practicality of the device.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Please refer to Figure 1-Figure 4 An automobile welding fixture includes: a platform 1, a support frame 2, an adjustment mechanism 3, and a fixing mechanism 4. The support frame 2 is fixedly connected to the bottom of the platform 1. The adjustment mechanism 3 for adjusting the position of the automobile part during welding is provided above the platform 1. The number of the adjustment mechanisms 3 is symmetrically arranged at both ends of the platform 1. The fixing mechanism 4 for fixing the automobile part is provided on the outside of the adjustment mechanism 3.

[0036] Specifically, the adjustment mechanism 3 includes a placement rack 5, a connecting rack 6, a flip assembly, and a buffer assembly. The placement rack 5 is arranged above the platform 1, and the connecting rack 6 is fixedly connected to the upper middle part of the platform 1. One end of the placement rack 5 is rotatably connected to the platform 1 through the connecting rack 6.

[0037] Furthermore, the flipping assembly includes a first electric telescopic rod 7, a first fixed seat 8 and a second fixed seat 9. The first electric telescopic rod 7 is arranged between the placement rack 5 and the platform 1. The end of the first electric telescopic rod 7 is rotatably connected to the platform 1 through the first fixed seat 8. The middle part of the placement rack 5 is fixedly connected to the second fixed seat 9, and the telescopic end of the first electric telescopic rod 7 is rotatably connected to the second fixed seat 9.

[0038] Furthermore, because the automobile parts are heavy and the automobile parts that have just been welded are relatively fragile, in order to prevent the automobile parts from being damaged due to vibration during the process of lifting and lowering the placement rack 5, the buffer assembly includes a pressure plate 14, a movable rod 15 and a spring 16. The movable rod 15 is fixedly connected to the top of the platform 1 and at a position corresponding to the placement rack 5. The top of the movable rod 15 is fixedly connected to the pressure plate 14. The outer side of the movable rod 15 is provided with a spring 16. The two ends of the spring 16 are fixedly connected to the pressure plate 14 and the platform 1 respectively.

[0039] Furthermore, in order to quickly cool down the automobile parts after welding is completed, a plurality of fans 17 are embedded and fixedly connected to the inner side of the placement rack 5.

[0040] It can be seen that when in use, the automobile parts can be placed on top of any placement rack 5 for welding. During the welding process, the first electric telescopic rod 7 can be gradually started to slowly lift the placement rack 5, thereby changing the welding angle of the device, making the welding effect more accurate, and the first electric telescopic rods 7 on both sides can be started at the same time to lift the two placement racks 5 at the same time and clamp and fix the two sides of the automobile parts, so as to weld the side of the automobile parts, and then the placement rack 5 corresponding to the unwelded side is slowly lowered, and the automobile parts clamped between the two placement racks 5 will gradually fall down along the lowered placement rack 5, thereby facilitating welding on the other side of the automobile parts. The entire process does not require the aid of additional tools, which effectively improves the working efficiency and practicality of the device.

[0041] Example 2:

[0042] The automobile welding fixture provided in Example 1 is further optimized, specifically, as Figure 3-Figure 5 As shown, further, the fixing mechanism 4 includes a cross bar 11, a rotating rod 12, a fixed head 13 and a driving assembly. The two sides of the placement rack 5 are fixedly connected with the cross bars 11, and the outer sides of the two cross bars 11 are provided with rotating rods 12. The middle parts of the two rotating rods 12 are respectively rotatably connected to the surfaces of the two cross bars 11, and one end of the rotating rod 12 is fixedly connected with the fixed head 13.

[0043] Furthermore, the driving assembly includes a second electric telescopic rod 10, and the second electric telescopic rod 10 is arranged below the placement rack 5. The ends of the two rotating rods 12 away from the fixed head 13 are respectively rotatably connected to the two ends of the second electric telescopic rod 10.

[0044] It can be seen that when the automobile parts are placed on the placement rack 5, the second electric telescopic rod 10 can be started, so that the second electric telescopic rod 10 is extended and drives the rotating rods 12 on both sides of the placement rack 5 to rotate. Because the middle part of the rotating rod 12 is rotatably connected to the cross bar 11, when the second electric telescopic rod 10 is started, it will drive the fixed head 13 to rotate along the cross bar 11, and then the automobile parts placed on the placement rack 5 are clamped and fixed by the fixed head 13. When the automobile parts are adjusted in angle or turned over, they slide off the placement rack 5, which effectively improves the stability and practicality of the device.
