What are the inspection components for automobiles?
With the progress of the requirement for the accuracy of commodities in industrial production, the requirement for the accuracy of automobile manufacturing is also constantly improving. At this time, it is necessary to use automobile inspection tools. The orientation and viewpoint of the probe can be set arbitrarily according to the user's needs. The measurement process can be completed automatically and the inspection data can be directly entered into the database. The higher-end flexible inspection system has the function of error data analysis, and the data can be used for calculation process control. What inspection components do automobile inspectors have? How should automobile inspectors be maintained?
1. With regard to the main appearance of the parts, the movable assembly can be used to check the smoothness under the structural constraints. Each movable assembly has at least two ducts or guide pillars. Movable blocks are fastened quickly with equipment. The distance between the catheter or guide post is not less than 200 mm. Aluminum alloy or wood substitution can be selected for block inspection.
2. Inspection pin is composed of guide, inspection and handle. In order to ensure the inspection pin to be inspected smoothly, it is necessary to install guide sleeve, which is bonded with the inspection fixture. The length of cooperation between inspection pin and guide sleeve must be 2.5 times larger than the diameter of cooperation and more than 20 mm. According to the different holes, they are mainly divided into cylindrical check pin and elliptical pin edge pin (some of which are checked), which need to be used in cooperation with anti-rotation guide sleeve. Pin materials are selected 45# steel, some of which are quenched, and the hardness reaches HRC 40-45. The pin should be blackened and marked.
3. Section template is used to inspect the profile with installation request. Excellent steel or hard aluminium plate with 6 mm thickness is selected as the template, and some cutters with 2 mm thickness should be made for inspection. The structure is divided into rotary type and penetrating type; the gap between the sample plate and the inspection parts is 3mm, and the section template should be positioned in the normal direction of the profile as far as possible, and the coordinates should be integer. The thickness of the support and the base plate of the cross-section template should be greater than 10mm, the material thickness should be added when the support is greater than 150mm, and the rigidity of the support can be enhanced by adding reinforcing bars when the height is 150-300mm, and when it is greater than 300mm, the rigidity of the support should be strengthened. Install support support under the support. Section template should be stable and free of loosening on the inspection fixture, and have installation orientation, without interfering with positioning pins and clamping equipment.
4. The stop gauge (stop bar) consists of a pass section, a handle and a stop section. It is mainly used for checking the profile.
The use of automobile inspection tools can be used to control the simplicity of various sizes of commodities in automobile production (such as aperture, space scale, etc.) and to improve the power and control quality of production.
