Description

Technical Field

[0001] The utility model relates to the technical field of automobile trial production welding, and particularly relates to a trial production multi-functional clamping plate. Background Art

[0002] In the automotive manufacturing industry, body welding plays a crucial role. It is not only the core link in the process of building a whole vehicle but also one of the most critical technical challenges during vehicle model updates. The advancement of welding technology and the level of production efficiency directly reflect the manufacturing standards, quality, production cycle length of automotive products, and the enterprise's ability to respond to market changes. In the traditional automotive welding process, precise positioning is often achieved by customized tooling fixtures, which ensure the precise docking and stable fixation of welded components.

[0003] In the trial production stage of products, in order to accelerate the R & D cycle, optimize cost control, and improve production efficiency, while ensuring that the produced prototype vehicles can meet strict dimensional tolerance requirements, enterprises usually need to design and manufacture a large number of simple toolings. These simple toolings, with their advantages of strong flexibility, low cost, and short production cycle, play an irreplaceable role in the trial production process, effectively balancing the dual requirements of quickly responding to market demands and ensuring product quality.

[0004] However, the existing simple toolings are specifically designed for the trial production welding stage. They generally adopt the form of machining and assembly, and design positioning blocks, adjustment blocks, and clamping blocks according to the detailed information of product positioning. Although compared with formal production fixtures, simple toolings have the advantages of simple production and quick response, due to the accuracy limitations in the processing process, they usually still need to be calibrated and adjusted with the help of a coordinate measuring machine to ensure the accuracy of positioning. In addition, since simple toolings are mainly made of metal materials, their weight and volume often make manual handling and installation inconvenient, increasing the operation difficulty and efficiency loss. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a trial production multi-functional clamping plate, which can reduce the number of machined parts, cancel the calibration and adjustment process, reduce the number of toolings, quickly inspect the product quality, reduce the labor intensity of workers, and ensure the stability of product quality.

[0006] To achieve the above purpose, the present application proposes a trial production multi-functional clamping plate, including:

[0007] A clamping plate body, whose shape matches the profile of the middle channel of the body to be welded;

[0008] The first stud welding guiding holes are symmetrically arranged at the front part of the clamping plate body, and their positions match the positions where the first stud welding screws need to be driven in the middle channel of the body to be welded;

[0009] The second implant welding guide hole is arranged in the middle front part of the clamping plate body, and its position matches the position where the second implant welding screw needs to be driven in the middle channel of the vehicle body to be welded;

[0010] The third implant welding guide hole is arranged in the middle rear part of the clamping plate body, and its position matches the position where the third implant welding screw needs to be driven in the middle channel of the vehicle body to be welded;

[0011] The solder joint positioning hole is arranged on the outer periphery of the clamping plate body, and its position matches the position where spot welding needs to be performed on the middle channel of the vehicle body to be welded;

[0012] There are at least two clamping plate boss pins arranged under the clamping plate body.

[0013] In one embodiment, the clamping plate body is attached and positioned by using the feature surface with the profile surface and the trimming edge of the middle channel of the vehicle body to be welded.

[0014] In one embodiment, it further includes:

[0015] Transverse reinforcing ribs arranged in parallel and longitudinal reinforcing ribs arranged in parallel.

[0016] In one embodiment, it further includes:

[0017] Handles symmetrically arranged on both sides of the clamping plate body.

[0018] In one embodiment, the inner diameters of the first implant welding guide hole, the second implant welding guide hole, and the third implant welding guide hole match the outer diameter of the welding torch head.

[0019] In one embodiment, the clamping plate boss pin extends into the positioning hole of the middle channel of the vehicle body to be welded for positioning.

[0020] In one embodiment, the outer diameter of the clamping plate boss pin matches the theoretical inner diameter of the positioning hole on the middle channel of the vehicle body to be welded.

[0021] In one embodiment, the handle is fixed on the clamping plate body through the cooperation of the handle seat and the bolt.

[0022] In one embodiment, the clamping plate body is integrally formed by 3D printing.

[0023] In one embodiment, the material of the clamping plate body is PLA.

[0024] The above technical solution adopted by the present utility model has the following advantages compared with the prior art: In this application, the boss pin can accurately position the holes on the middle channel of the body to be welded, and at the same time can check whether the aperture of the product meets the standard. The feature surface is closely attached to the surface of the middle channel of the body to be welded to achieve conforming positioning, and can also be used to check whether the surface of the product meets the requirements. In addition, the design of the spot welding holes can quickly and accurately identify the position and quantity of the welding points, effectively reducing the risk of missing welding points. The stud welding guide holes are precisely matched with the welding gun head to ensure the position accuracy of the stud welding nails. For the convenience of manual operation, a handle is also provided on the clamping plate for easy taking. BRIEF DESCRIPTION OF THE DRAWINGS
