Kvalitetskontrollen av biltäckande delar är processen att mäta olika täckningsdelar med olika mätmetoder enligt kvalitetsegenskaperna för olika täckningsdelar . Kvalitetskontrollmetoderna är följande:
(1) The quality characteristics of the raw materials of automobile covering parts were verified. In the forming process of automobile cover parts, deep drawing is required for many times, so it is necessary to verify the special parts that affect the forming and deep drawing of stamping parts. Raw material quality inspection is to inspect the shape, size, mechanical properties and chemical composition of raw materials according to the items and methods specified in the Inspektionsinstruktioner . Frekvens och materialstandarder krävs .
(2) Car panel size verification. The stamping dimensions of the four doors and two covers of the car are usually sampled and checked with a standard sample frame to determine whether the panel size meets the requirements. The standard frame is designed and manufactured according to the shape, size and assembly requirements of the four door panels and the two cover panels. In order to ensure the stamping dimensions of the four-door and two-cover automobile cover parts, the measurement points of these standard frames should be regularly checked. Standard samples should be used daily to calibrate the measurement points. The dimensional test results of the standard frame, the test results of the measurement points of the standard frame, and the calibration results of the measurement points of the standard frame are determined by the relevant Personal . Inspelning och analys av dimensionell stabilitet .
(3) Dimension verification of the assembly position of the automotive panel products. The dimensions of the four doors and two covers, the left and right sides, and the assembly position of the body stamping parts are usually detected by flexible detectors and cantilever coordinate measuring instruments. The stability and data analysis of these instruments are regularly controlled by the three-coordinate laboratory. The complex shape of these panels makes it difficult to manufacture and use standard frames, so automotive companies often use flexible test tools to measure the dimensions of these components. At present, foreign auto companies have widely used laser measuring instruments to measure 100% of the car body. The online measurement system is a measurement system widely used internationally. A measurement system widely used by mainstream automobile manufacturers. It uses the laser probe and camera mounted on the robot to sample and measure the body surface, holes and grooves. Compared with the three-coordinate measurement, the level of human body quality has been greatly improved. The online measurement system Har fördelarna med kort mätningstid, 100% mätning, realtidsavvikelsedetektering och realtidslarm . genom de kompletterande fördelarna med online-mätningssystemet och koordinatmätningen, den storleksstatus för människokroppen kan vara bättre grepp, vilket hjälper till att förbättra storleken och kvaliteten på människokroppen . it är värt att notera att det är värt att vara bättre grepp, vilket hjälper till att förbättra storleken och kvaliteten på människokroppen. parts should be carried out under the same production conditions, and the production batch number of each batch of automobile covering parts should be maintained. Qualified panels should be issued according to the batch number for retrospective inspection. All defective products discovered during the inspection must be recorded and analyzed according to the production lot number, and the relevant departments should take corrective measures and quality improvements at the same tid .
