This fixture has a simple and reliable structure, effectively solves the aforementioned technical problems, and is suitable for widespread use. To achieve the above objectives, this utility model employs the following technical solution:

[0004] A welding fixture for automotive components includes a base plate, a limiting support assembly, and a clamping assembly. The limiting support assembly comprises six sets: two sets are spaced longitudinally, two sets are spaced laterally, and two sets are arranged at an inclined direction forming a 60-degree angle with the lateral direction. Each limiting support assembly includes a fixed plate, a vertical plate, a support plate, and a limiting piece. The fixed plate is fixedly mounted on the base plate.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0014] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] To solve the above technical problems, such as Figure 1-2 As shown, this embodiment designs a welding fixture for automotive components, including a base plate 1, a limiting support assembly, and a clamping assembly. There are six sets of limiting support assemblies, of which two sets are arranged longitudinally at intervals, two sets are arranged laterally at intervals, and two sets are arranged in an inclined direction, forming a 60-degree angle with the lateral direction. By setting six sets of limiting support assemblies, which are arranged at intervals along the longitudinal, lateral, and inclined directions (forming a 60-degree angle with the lateral direction), the approximate L-shaped automotive components can be stably supported and precisely limited from all directions and multiple angles.

[0017] The limiting support assembly includes a fixed plate 2, a vertical plate 3, a support plate 4, and a limiting piece 5. The fixed plate 2 is fixedly installed on the base plate 1. The vertical plate 3 is perpendicular to the fixed plate 2 and connected to one end of it. The support plate 4 is attached to one side of the vertical plate 3. The support plate 4 is provided with bolt connection holes. The vertical plate 3 is provided with four symmetrically arranged waist-shaped adjustment holes 6. Bolts are inserted into the waist-shaped adjustment holes 6. After the bolts pass through the waist-shaped adjustment holes 6, they cooperate with the bolt connection holes on the support plate 4, allowing the support plate 4 to flexibly adjust its position within a certain range. This allows the position of the limiting piece 5 to fit the workpiece more closely. In addition, since the support plate 4 is easy to assemble and disassemble, it is also possible to replace the support plate 4 with different limiting pieces 5 according to the actual shape and size of the workpiece.

[0018] The limiting piece 5 is fixedly connected to the support plate 4. The limiting piece 5 is provided with a curved arc-shaped pressure hole, which can closely fit the curvature of the workpiece surface, provide a more reliable limiting effect, prevent the workpiece from shifting during the welding process, and also avoid scratching the workpiece.

[0019] The clamping assembly is used in conjunction with the limiting support assembly to clamp the workpiece. The clamping assembly includes a support 7, a linear clamping actuator 8, and a clamping block 9. The support 7 is fixed on the base plate 1, and the linear clamping actuator 8 is mounted on the support 7. The linear clamping actuator is connected to the clamping block 9. Specifically, the linear clamping actuator 8 is preferably a latch-type quick clamp. The latch-type quick clamp includes a handle and a push rod. The handle design of the latch-type quick clamp allows the operator to easily drive the push rod to move linearly through a simple rotation, thereby pushing the clamping block 9 to accurately clamp the workpiece and ensure the stability of the workpiece during the welding process. This clamping method is not only easy to operate and saves clamping time, but also, through close cooperation with the limiting support assembly, further enhances the workpiece fixing effect, providing a strong guarantee for achieving high-precision and high-efficiency welding of automotive parts.

[0020] In this embodiment, it is further preferred that at least two sets of clamping components are provided in the longitudinal direction and at least one set of clamping components are provided in the transverse direction, which can provide a denser and more reasonable distribution of clamping points for the special shape of the approximately L-shaped decorative part. This layout ensures that the workpiece is subjected to uniform and comprehensive clamping force during the welding process.

[0021] In this embodiment, it is further preferred that a roller 10 is provided at each of the four corners below the base plate 1. The two left and right rollers 10 on one side are directional rollers, and the two left and right rollers 10 on the other side are omnidirectional rollers. This design greatly improves the mobility and flexibility of the welding fixture. The directional rollers can ensure the stability of the fixture when moving in a straight line and prevent the fixture from deviating during the pushing process, while the omnidirectional rollers give the fixture all-round turning ability, which makes it convenient for operators to quickly adjust the position of the fixture according to the workshop layout and production needs.

[0022] Considering that there is no point of force application when the device moves, in order to solve this problem, such as Figure 3 As shown, based on the above embodiment, a further improvement is made by providing a pull rod 11 on the base plate 1. One end of the pull rod 11 is mounted on the base plate 1 through a mounting seat. The pull rod 11 and the mounting seat are rotatably connected. This improvement provides a convenient means of moving the tooling. The operator can easily apply force through the pull rod 11 to push or pull the tooling in a time-saving and labor-saving manner.

[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
