As a non-standard process equipment, the design and manufacturing cycle is long, as the vehicle project cycle is getting shorter and shorter, the development speed of the gage needs to be improved accordingly, in order to improve the overall competitiveness. The cycle of vehicle replacement in the 1950s of the last century was about 15 years, the cycle of vehicle replacement in the 1980s was about 7 years, and the development cycle of current domestic models was shortened to 2-3 years. In order to meet the needs of the development of the automobile industry and adapt to the rapidly changing market requirements, the automobile final assembly factory continues to accelerate the pace of research and development, control production costs, and constantly launch new models to increase market share under the pressure of the environment.

In order to face the reality of the continuous shortening of the automotive development cycle, the automobile inspection manufacturers in developed countries such as the United States and Germany have changed the traditional overall design method in the inspection design stage, and put forward the concept of the combination module of the inspection tool, and a large number of common standard parts are used in the design and manufacturing of the inspection tool, using the module assembly combination method. The production efficiency of measuring tool processing and manufacturing is effectively improved.

In the design process of the gage, the Japanese company put forward a comprehensive computer information management method, and invested a lot of technical strength in information management from the formal design stage of the gage to the final debugging stage. The shared platform created can transmit and store information about various problems in the whole process of the gage development. An effective technical circulation system has been formed among various related departments. The problem feedback mechanism established by this management mode effectively realizes the flatness of problem solving, and accumulates the experience and lessons in the design and manufacturing of the gage, and can constantly improve the technical standards in the process.

Advantages of parametric design of gage:

1) The parametric design of the check can effectively improve the automation level of the design, and well promote and support the innovative design and rapid design of new products

2) Reduce the labor intensity of designers, improve the design efficiency, and reduce the product design cycle

3) In the market environment of mass customization production and requiring innovation, this development trend is particularly important for the survival, competition and development of enterprises.

The standardization and universality of the gage are two aspects related to each other, on the basis of the development of a typical gage structure, first of all, the universality of the gage components and components, the establishment of type size series or variants, in order to reduce the type of similar functional uses of the gage components and components, excluding some of the poor functional structure, the universality of the method includes the universality of the gage, components, components, and materials. The standardization of the gage is conducive to the commercial production of the gage, to shorten the production preparation cycle and reduce the total production cost. A large number of standard parts used by the tester can reduce processing time and cost, improve interchangeability, greatly shorten the design cycle, greatly reduce the design error rate, and improve the manufacturing level of the parts of the tester. A perfect standardized system of the tester will make the design and manufacture of the tester more handy, making it easier for us to strengthen the process control. Promote the improvement of gage quality, so that the gage has a higher market trust. By purchasing standard parts of the gage, the preliminary estimate can reduce the production cost by 20%-30%.

At present, China's auto inspection market has formed a standardized module system, but it still needs more development and improvement. Professional company provides standardized horizontal turning mechanism, sliding mechanism, positioning pin, plate mechanism, guide pin, guide sleeve and other standard database and standard parts, for the modular, serialization, parameterization provides technical support.
