What is a car inspection tool? Analysis of inspection fixture and automobile fixture
With the continuous development of science and technology, more and more automobile manufacturers use inspection tools for testing, which not only greatly improves the work efficiency, but also ensures the accuracy of data. What is a car inspection tool? The inspection tool is a special inspection tool designed and made to facilitate the inspection of quality during mass production. The inspection tool is more time-saving and labor-saving than the inspection with general measuring tools, and the automobile inspection tool is a tool specially used to measure the dimensions of automobile parts.
Specifically, the automobile inspection tool is a special inspection equipment used to measure and evaluate the size and quality of parts. On the part production site, the on-line inspection of parts is realized through the inspection tool. Therefore, it is necessary to accurately install the parts on the inspection tool, and then check the part surface and periphery through visual inspection, or measuring table, or caliper, The holes with different properties on the parts and the connection position between the parts can also be visually inspected with the help of inspection pins or visual inspection, so as to ensure the rapid judgment of the quality state of the parts during production.
Working principle of automobile inspection tool:
1. High speed and high-precision visual processing technology is used to automatically detect various mounting errors and welding defects on PCB board. PCB board can range from fine spacing high-density board to low-density large-size board, and provide on-line detection scheme, so as to promote the progress of production efficiency and welding quality. Automobile inspection tools use AOI as a tool to reduce defects, Find and eliminate errors early in the assembly process to achieve good process control.
2. For some extremely important functional dimensions on the parts, the inspection tool can also be used for numerical detection. Generally, the accurate coordinate value of the parts based on the body coordinate system cannot be obtained directly with the help of the inspection tool, but the parts can be obtained only by placing the parts on the inspection tool and measuring with a CMM. The structure of the modern inspection tool can be used as a measuring support at the same time, However, when the online inspection function of the gauge and the measurement support function cannot be met at the same time, the online inspection function of the gauge shall be met first.
3. The automobile inspection tool is a special inspection equipment customized according to the requirements of the demander. The design of the inspection tool * * * is based on the * * * final 3D data and 2D drawings provided by the customer. The 3D data * * * has a correct automobile coordinate system. The design and manufacture of the inspection tool need to be approved by the customer before processing and delivery. The measuring support is an auxiliary support when measuring parts with a CMM, All support surfaces (points) and positioning datum planes are * * * milled according to the CAD data of parts. The measuring support of some special parts shall also have the function of some inspection tools.
