How does Jingke Xingye ensure the high precision of automobile inspection tools?

In the process of processing and assembly of automobile body, in addition to the influence of subjective factors such as the operator's own skills and experience, there are also various errors caused by the detection method itself.

There are two more typical cases:

1.Most of the body and its components are sheet metal parts, the rigidity of the workpiece is generally poor, and the various holes and relative sizes on the surface of the body are in a deformed state due to the influence of the earth's gravity. If the traditional measurement method and fixture method are used, this natural deformation cannot be measured and evaluated, and even if the measurement and evaluation, there will be a large deviation.

2.Automobile body assembly parts are multi-work parts assembly system, it is difficult to avoid the existence of deviation in single-piece detection.

In view of the above reasons, the main requirements for body inspection are: reasonable positioning; The detection of holes includes two contents: aperture size and hole position; Shape inspection: As the contour of such parts is generally free-form curved surface, irregular and other characteristics, various methods need to be adopted according to the specific situation; Check the contour of the workpiece by marking, the situation is similar to that of the inspection hole; The parts to be tested need to be clamped.

Traditional inspection tools are generally only for a parameter test, mostly manual operation, work efficiency is not high. In addition, there are many shortcomings in the traditional inspection and inspection fixture, do not have the ability to monitor the operation of the production line. ThereforeJingke XingyeIntroduced high precisionCoordinate Measuring Equipment（Accuracy can be achieved0.002mm）,Including Italy imported Hexcon automatic three coordinate measuring instrument1(travel is3300*2000*1000mm）,Joint venture brand automatic three coordinate measuring instrument2Table (travel5000*2500*1500mm）, to carry outAutomobile checking fixtureThe detection.

High precisionCoordinate Measuring Equipment

CMM generally has high precision, high speed, good flexibility, strong data processing and the ability to adapt to the field environment, especially the rich and expanding software functions, all of which makeCMM is playing a more and more important role in the quality control of body. Especially in today's car production workshop, coordinate measuring machine has been used in the production line, rather than in the measurement room away from the site. In the stamping parts production workshop, the proportion of the use of three-coordinate measuring machine detection has been more than half, some large complex workpiece inspection ratio.Higher. Not every weldment needs to be inspected, but in those body assemblies that must be controlled, the proportion of inspections using coordinate measuring machines even reaches 2/3. The three-coordinate measuring system used for detection in the production process has in fact become an integral part of the process.
