Research on the control points of automobile parts on the ac

In the automobile manufacturing industry, the precision of parts is directly related to the performance and quality of the whole vehicle, and it is one of the important indicators to measure the level of automobile industry in a country or region. With the continuous improvement of consumers' requirements for vehicle safety, comfort and environmental protection, how to effectively control and improve the accuracy of automobile parts processing and manufacturing has become a key issue in the industry. This paper will discuss the key points of controlling the accuracy of automobile parts from the aspects of design, material selection, technological process and testing technology.

I. Design stage

1. Advanced computer-aided design (CAD) and simulation analysis software are used for product development, and the structural layout is optimized in the virtual environment to ensure the close cooperation between all parts.

2. Considering the influence of practical environmental factors such as temperature change and vibration, the tolerance range is set reasonably to meet the needs of different working conditions.

3. Introduce the modular design concept, realize rapid assembly through standardized interfaces, and reduce accumulated errors.

Second, the material selection

1. Select suitable materials according to functional characteristics and working conditions to ensure that they have sufficient strength, toughness and wear resistance.

2. For the key parts that are easy to be eroded by corrosion, we can consider adding protective coating or using corrosion-resistant alloy materials.

3. Pay attention to the development trend of lightweight, explore the application potential of new composite materials, and reduce the body weight while maintaining good mechanical properties.

Third, the production process

1. Implement lean production mode, strengthen on-site management, and prevent waste.

2. Promote the construction of automated production lines, use robots to complete difficult tasks, improve work efficiency and reduce quality problems caused by human operation errors.

3. Strengthen equipment maintenance and calibrate measuring tools regularly to ensure stable and reliable machining accuracy.

Fourth, quality inspection

1. Establish a sound quality management system and strictly implement various standards and specifications.

2. Use 3d scanner, optical microscope and other precision instruments to conduct a comprehensive inspection of the finished products and find potential defects in time.

3. Implement a sampling re-inspection system for special links and strengthen supervision.

To sum up, to achieve high-quality automobile parts production, we must start from the source, pay attention to every detail, and form a complete closed-loop control system. With the development of intelligent manufacturing technology in the future, I believe we can better solve this problem and push China automobile industry to a higher level.
