With the increase in the accuracy requirements for products in industrial production, the requirements for automobile manufacturing precision are also increasing. At this time, the use of automobile inspection tools is required. The position and angle of the probe of the car gage can be arbitrarily set according to the user's needs. The measurement process is automatically implemented and the test data is directly entered into the database. The higher-end flexible gage system has the error data analysis function, and the data can be used for statistical process control. So what are the detection components for car inspection?
1. Active blocks For the important surfaces on the parts, in the case of structural constraints, the flatness can be checked by using an active fight. Each active block has at least two conduits or guide posts. The movable blocks are fastened with a rapid tightening device, and the spacing between the guide tubes or the guide columns is not less than 200 mm. The aluminum or substitute wood structure may be used for the test section of the blocks.
2. The inspection pin consists of three parts: guide, inspection and handle. In order to ensure the smooth detection of the inspection pin, the guide sleeve must be installed. The guide sleeve and the inspection tool body must be bonded together. The length of the inspection pin and the guide sleeve must be matched. Greater than 2.5 times the diameter of the fit and greater than 20mm. According to the different holes are mainly divided into cylindrical detection pin and elliptical pin type pin (detection part), need to be anti-rotation need to be used in conjunction with anti-rotation guide sleeve. Pin material selection 45 # steel, working part for quenching Hardness reaches HRC40-45, blackening treatment, and marking.
3, section model for the detection of the installation requirements of the profile, the model uses a thickness of about 6mm of high-quality steel or hard aluminum, in the detection part should be made about 2mm knife edge for testing. The structure is divided into rotary type and insert type; the gap between the model and the test part is 3mm, and the cross-section model should be arranged as far as possible in the normal direction of the model surface, and the coordinates should be taken as an integer. The thickness of the model support and floor should be greater than 10mm. When the bearing is larger than 150mm, the material thickness should be increased. When the height is 150-300mm, the rigidity of the bearing can be strengthened by adding stiffeners. When it is greater than 300mm, the support bearing should be installed under the bearing. The section model is on the inspection tool. To be stable, no loose, and there is an installation position, do not interfere with the positioning pin and clamping device.
4, stop regulation (through stop bar) has a pass section, handle and stop the composition, mainly used to detect the use of profile.
The detection elements for the car inspection are shared here today. The use of the car inspection tool can be used to control the simple tools of various sizes (such as aperture, space size, etc.) of the products in the automobile production, and improve the production efficiency and control quality.
