Lamp checking fixture

The lamp inspection tool can reproduce the state of the lamp installed on the car body, and can directly or indirectly measure and evaluate the dimensional relationship (clearance and surface difference) between the car body and the lamp by using the size inspection tool. It is mainly used for the precision determination and adjustment of the mold and tooling in the production preparation stage and the daily management of the size after mass production.

The whole set of inspection tools of Jingke Company is made of aluminum alloy. The most important part of the design of the lamp inspection tool is to completely reproduce the actual installation method of the lamp, so the structure of the lamp installation part needs to be determined according to the requirements of GD & T drawings and according to the actual loading state position structure; According to the datum distribution method, it is divided into: surface datum, hole datum and auxiliary datum. It is required that the mounting part of the lamp body must be able to withstand the rotation force of the installation strength of the vehicle body to prevent the occurrence of falling off and rotation during the loading and unloading of the lamp.

Beijing Jingke has the comprehensive strength of design, manufacture, assembly, debugging and measurement of a full set of inspection tools, and has developed various types of auto parts and assembly inspection tools, including: welding assembly, front and rear windshield, front and rear lamp assembly, floor assembly, four doors and two covers, instrument panel assembly, door inner guard panel assembly, bright trim strip, glove box assembly, coat rack assembly, sunroof assembly, front and rear bumper assembly, opening inspection fixture, pipeline inspection fixture, measuring bracket, tooling fixture, etc.

With excellent product quality and considerate after-sales service, Beijing Jingke has been cooperating with FAW-Volkswagen, FAW Toyota, Beijing Benz, Beijing Hyundai, Beiqi Foton, Great Wall Motors, Shenlong Motors, Fiat, Wuling Motors and other well-known domestic and foreign OEMs and parts The factory maintains extensive and close cooperation. Jingke will continue to expand its product varieties and actively explore flexible gauges that save costs, shorten construction periods, can be recycled, and have high-tech content for customers.

This car inspection tool is a car light inspection tool for detecting car headlights (far and near beams). The shell of the car light is an injection molded part. The overall dimensions of this car gauge are 600mm * 550mm * 745mm and weigh 57kg. The frame of the automobile lamp inspection tool is designed and manufactured according to the shape and size of the lamp housing injection molded parts. The frame and base of the lamp inspection tool are made of different aluminum materials, which is a fulcrum type, which greatly reduces the weight of the lamp inspection tool. The detection body of the lamp inspection tool is made of substitute wood material, which has good dimensional stability and wear resistance, which ensures the service life of the lamp inspection tool.

The car headlight matching inspection tool is used to detect whether the installation of the car headlight part matches, and install the headlight simulation block on the body frame. Because the installation hole of the headlight simulation block is completely consistent with the design of the car light, It can simulate the matching state of the car lights and surrounding parts during loading. Because of the loading state, the actual measurement of the parts can also be carried out by the three-coordinate measuring machine, the specific body parts data can be obtained, and the parts are compared and analyzed with the parts model, and the error value of the parts can be obtained quantitatively, so as to accurately correct the parts.

Product installation steps

1. Open the turning mechanism and pull the movable block of the guide rail.

2. Place the product on the inspection fixture to make the product fit with the positioning surface on the positioning block/support surface; Then push the movable positioning block into the positioning position, insert the locking detection pin into the corresponding hole, and lock it to complete the positioning of the product.

3. After the product positioning is determined to be stable, rotate the turning mechanism to the detection position to make the product in a state to be detected.

Detection

1. Contour detection: Use clearance ruler or stop gauge to measure the 3mm clearance surface as required.

2. Face difference detection: use face difference gauge or face difference gauge to measure the face difference of the product as required.

The automobile headlight shell checking fixture improves the production quality of plastic parts of lamps and lanterns by controlling the shrinkage and deformation of the headlight shell. The overall dimensions of this headlight housing gauge are 680*520*470mm and 28kg.

The front combination lamp housing inspection fixture is used to detect the outer contour surface of the automobile headlight housing.
