A Brief Discussion on the Design and Manufacturing of Inspection Tools for Autom

With the continuous improvement of people's living standards, cars have become a basic configuration. The requirements for automobiles have shifted from earlier practicality to current aesthetics. To achieve a car, it is necessary to improve the quality of its parts. As an important monitoring equipment for detecting stamped parts of the vehicle body, gauges play a decisive role in controlling the quality of the vehicle body. In China, with the rapid development of the automotive industry, inspection tools have also been applied. Overall, China's gauge design is relatively mature and has corresponding technical talents for gauge research, which plays a promoting role in the application of automotive gauge technology.

The connotation of automotive stamping parts inspection tools

Measuring tool is a simple tool used in offline production to control various dimensions of products, which is conducive to improving production efficiency, controlling production quality, and has good practicality for large-scale product production. It is currently widely used in China's automotive parts production to replace measuring tools. The automotive stamping parts inspection tool is a tool used in the production process of automotive parts.

Currently, inspection tools have been widely used in the automotive industry, and stamping part inspection tools are a relatively simple and effective method for quality inspection of automotive stamping parts. The measuring tool itself is a three-dimensional measuring tool. In practical use, it can accurately measure the dimensions of stamped parts and make judgments on the quality of the parts. If a non-conforming part is found one day, the cause analysis can be carried out based on the inspection data, and then targeted adjustment measures can be made to improve its overall quality. The use of gauges in the production process of automotive stamping parts has many advantages, such as simple operation, easy modification and updating, and no damage to the parts themselves. In order to verify the properties and characteristics of the equipment itself, it is often made of resin or steel structural materials. Of course, the gauge is not a simple model, and there are corresponding adjustment devices that can fix and clamp the stamped parts. According to practice, the stamped parts detected by the gauge are basically verified to be qualified and have properties.

Design points of 2 automotive stamping parts inspection tools

2.1 Fixture design needs to prioritize humanization requirements

Although the production of inspection tools is for testing automotive stamping parts, their function is to ensure the production quality of automotive stamping parts. However, to achieve this detection process, it requires human operation. In automobile production, not every part is relatively small, and larger parts require lifting devices to operate. Therefore, in the design process, the operability, flexibility, and convenience of the measuring tool should be considered. For example, in the design process, it is necessary to fully utilize the specific shape of the stamped parts and then conduct a reasonable investigation of the structure of the inspection tool based on its mechanical properties. In addition, the balance of large gauges should be maintained, and there should be no imbalance during lifting, which can easily cause on-site accidents.

2.2 Investigation of Manufacturing Materials in Gauge Design

Inspection tools are usually made of non-metallic materials in order to be lightweight and flexible. Currently, resin is mainly used for production in China. Resin itself has various characteristics such as low density, high strength, good performance, relatively lightweight overall, and not suitable for deformation. In addition, based on the humanized requirements mentioned above, the author believes that its height needs to be designed in proportion to the average height of the public. Furthermore, in the process of material selection, it is necessary to fully consider the customer's needs. If the customer requires lightweight gauges, resin should be the main material, while if the customer's requirements are relatively high, steel materials can be used for manufacturing.

2.3 Accuracy of Benchmark Design

Benchmark design is an important part of gauge design. In this design, it is necessary to first design the benchmark of the gauge based on the dimensions of the gauge and the position of the measured part in the vehicle body coordinates, in order to determine the three upward reference planes of the gauge's length, width, and height. Then, based on the data of the inspected stamped parts and the specific position of the stamped parts installed in the vehicle body, the form of the benchmark is determined.

2.4 Considerations for manufacturability

The final mouth of the gauge design is achieved through production to detect the mouth. Therefore, in the process of fixture design, its manufacturability is important. That is to say, the design of the entire gauge cannot be separated from the production of the gauge. During the production process, there may be ten factors that need to be considered in the design, such as whether there is technology to accurately produce it.

2.5 Artistic Appreciation Value

The measuring tool itself is just a testing equipment, but with the increasing assistance of people's spiritual culture, the artistic requirements for various instruments are constantly improving. Currently, many people have regarded the measuring tool as a work of art. And in the design process, designers need to have an artistic appreciation level and strive to achieve the beauty of their appearance as much as possible.

Manufacturing of 3 automotive stamping parts inspection tools

The design of measuring tools has been discussed from five aspects: practicality, feasibility, manufacturability, processability, and economy. Manufacturing requires meeting these five performance requirements based on the design. At present, the production process of inspection tools can be roughly represented.

3.1 Specific accountability in the following sequence

The entire production process cannot be completed by one production personnel. Therefore, during the production process, each production personnel needs to make their own production sequence rigorous. After the production is completed, the correctness of this sequence needs to be strictly checked. At the same time, the quality and correctness of the previous and subsequent sequences also need to be checked. Once problems are found, they need to be promptly raised and remedial measures taken.

3.2 The production of gauges is for scheme design

Generally speaking, the designer and maker of gauges are not the same person, especially in the current social context where many designers lack practical experience. Therefore, their designs are relatively idealized, and in the design process, the actual manufacturability is ignored. Therefore, the author believes that before production, the production personnel need to conduct research on the entire design, what kind of production should be used for different orders, and whether it can be achieved.

3.3 Inspection of Finished Inspection Tools

After the inspection tool is completed, corresponding inspections are required to ensure its accuracy after being put into use. Usually, inspection can be divided into two types, one is dynamic acceptance. That is to say, based on the corresponding parts, use the parts to verify their specific operability and performance., Static acceptance checks the accuracy of design data by measuring and comparing it with actual data.

With the gradual development of the automotive industry, the inspection tool industry will also become increasingly developed. In the future, the production of gauges will inevitably develop towards quantification and convenient operation, and gauges will also become an indispensable part of the automotive manufacturing process.
