Fixture Testing
The inspection efficiency of the fixture for stamping parts is an important issue. Stamping inspection is mainly carried out by manufacturers to determine whether the workpiece and stamping parts are qualified and whether they can be correctly put into use in a high-precision state.
Automotive Checking Fixture Company
Automotive checking fixture is a key component for improving production efficiency, as fixture testing can achieve fast and reliable inspection processes, utilizing automation for rapid inspection. By installing designed instruments on the assembly line, operators can easily operate them, improve productivity, and achieve efficient testing.
Design of Automotive Checking Fixture
1) Reliability and Durability Requirements
Automotive checking fixture is a tool used for frequent measurement and calibration, therefore their reliability and durability are also important factors to consider in design. Designers need to follow the following principles to achieve reliability and durability requirements:
- Appropriate Surface treatment: Improve the corrosion resistance, hardness, and wear resistance of the checking fixture through surface treatments such as chrome plating, nitriding, etc.
- Reasonable Structural Design: The structure of automotive fixture testings should be designed reasonably, with sufficient consideration given to strength and stiffness to avoid deformation or damage caused by loads.
- Choose Appropriate Materials: Automotive checking fixtures should be made of materials with good characteristics such as wear resistance, corrosion resistance, and deformation resistance to improve their service life.
2) Requirements for Practicality and Ease of Use
The designed automotive checking fixtures should have practicality and ease of use to improve production efficiency and operational convenience.
- Lightweight and Flexible: The measuring tool should be designed to be lightweight and convenient, easy to automotive and use, to meet the needs of different work scenarios.
- Simple and Easy to Understand: The designed automotive fixture testing should be simple and easy to understand, with clear and concise operation procedures, and can be operated without excessive training.
- Compliance with Operating Habits: The design of automotive checking fixtures should conform to the operating habits of operators, using user-friendly control components and interfaces to reduce operational burden.
3) Accuracy and Precision Requirements
Accuracy and precision are among the most fundamental requirements when designing automotive checking fixtures. Accuracy refers to the stability and repeatability of the measurement results of the checking fixture, while accuracy refers to the degree of closeness between the measured value of the checking fixture and the true value of the measured physical quantity. To meet these requirements, designers need to consider the following factors:
- Choose Appropriate Measurement Principles and Methods: Select appropriate measurement principles and methods based on the characteristics of the measured physical quantity to improve the accuracy and precision of the measurement
- Determine Appropriate Standards: Use precise and reliable standards to compare and calibrate fixture testings to ensure their accuracy and precision.
- Control Error Sources: Identify and control possible error sources that may be introduced in the design of the measuring tool, such as thermal expansion, material deformation, etc., to reduce the impact of errors on the measurement results.
Maintenance of Automotive Checking Fixture
The maintenance of automotive checking fixtures plays a very important role in accuracy and reliability. There are many maintenance steps, and the following are the key points and precautions for tool maintenance.
- Regular Maintenance: In addition to cleaning and calibrating automotive checking fixtures, operators will also perform regular maintenance and upkeep on some instruments. This may include lubricating moving parts, replacing worn parts, or adjusting sealing. Develop corresponding maintenance plans based on the type and requirements of checking fixtures, and strictly follow the operation manual.
- Clean Environment: Place the instrument in a dry, clean, and dust-proof place, avoiding contact with other hard or sharp objects to prevent scratches or damage to the instrument. After each use of the automotive checking fixture, it should be properly protected and stored. In addition, for instruments with special requirements, specialized protective covers can be used for special protection.
- Usage Steps: Proper use of automotive fixture testing plays an important role. If the instrument is overused or overloaded, it may cause damage to its structure and accuracy. It is very important to follow the correct operating methods and usage standards when using checking fixtures. If operated correctly, there will be no collisions, falls, or excessive external forces.
- Regular Inspection: Due to prolonged use, the accuracy of the automotive checking fixture may undergo significant changes, so the step of regular calibration cannot be omitted. Develop an instrument calibration plan based on usage frequency and regulatory requirements, and calibrate it through a professional calibration agency. The calibrated instrument must be labeled with a date and calibration result to assist in the next search and save time.
- Cleaning: Timely cleaning and inspection of automotive fixture testings by personnel is the key to maintaining their normal operation. Be sure to use a suitable cleaning agent and soft cloth to gently wipe the surface and contact area of the instrument to ensure the removal of impurities such as dust, dirt, and grease. Avoid using rough materials or chemicals to prevent damage to the instrument’s surface.
- Apply Rust Proof Oil: To prevent rust, technicians can apply a thin layer of rust-proof oil or rust inhibitor on the surface of the checking fixture and store it in a dry and ventilated place. automotive checking fixtures are made of metal materials and are easily affected by external factors such as moisture and humidity, which can cause metal parts to rust. In addition, avoid exposure to humid environments and acidic substances, and regularly inspect and promptly address any potential rusting issues.
The Role of Automotive Checking Fixture
- Implement online inspection of parts. Through automotive checking fixtures, the surface and periphery of parts can be inspected, and different types of holes on parts and the connection positions between parts can be visually inspected, thus achieving rapid judgment of the quality status of parts during trial production and initial production.
- For some extremely important functional dimensions on the parts, numerical testing can also be automotiveried out using automotive fixture testings: usually, it is not possible to directly obtain the precise coordinate values of the parts based on the vehicle coordinate system with the help of checking fixture. Instead, the parts are placed on the checking fixtures and measured by a coordinate measuring machine. The structure of the automotive checking fixture should also be designed to serve as a measuring bracket.
The automotive checking fixture is developed based on the special planning and design requirements of the current vehicle model. Automotive checking fixtures are highly accurate equipment that have certain requirements for the production environment. Effective control of product quality, size, and shape can be achieved through automotive checking fixtures.
