The three-coordinate measuring instrument is a high-precision measuring instrument that uses the unique coordinate value of each point of the parts and then processes the data through software. At present, with the development of precision measurement technology for many years, the CMM has a variety of measurement shapes and machine structures, and the CMM with the largest structure is the gantry type CMM.
Since the gantry type CMM is the largest three-coordinate of the structure, its measuring stroke is of course the largest, which also explains the application field of the gantry type CMM from the side, which is used to measure large workpieces. When measuring common workpieces, the bridge-type CMM is generally used for measurement. When the CMM is measuring, the Z axis must be able to move smoothly in the X and Z directions on the beam, and the beam also needs to be in the Y direction. Directional movement, in the bridge structure, the guide rails on both sides acting as bridge piers become very important, and with the increase of the measurement stroke, the weight of the beam and the Z axis will also increase, and the error will increase accordingly. Only the three-coordinate measuring instrument with the gantry structure is used, which is equivalent to adding piers and sharing the load-bearing force.
Automobile, aerospace, heavy transportation, mold, inspection tools, ships and other industries are the main application fields of gantry type CMM. The parts and components in these industries are characterized by high precision requirements and very large shape and volume, which cannot be measured by traditional measuring tools and bridge-type CMMs. Super-large workpieces such as large molds, automobile assembly inspection tools, ship engines, and aircraft parts can be perfectly inspected by the gantry type CMM.
The CMM is currently an indispensable testing instrument in the manufacturing industry, especially in the relatively prosperous automobile manufacturing industry. So what kind of great role has the gantry type CMM played in the automobile manufacturing industry?
First, it can ensure the smooth progress of the manufacturing process
In the manufacturing process of automobiles, some of the more important points are to ensure that the standards of the manufactured parts used are consistent in both production and design, so the operator is required to control the manufacturing process well. If the control standards are to be consistent, certain measurement tools must be used. After using certain measurement tools to measure the standard, if the subsequent standards are to be consistent, then the gantry type CMM will play a role at this time. its huge effect. It can be said that the gantry type CMM is the most convenient way to obtain the correct size in automobile manufacturing.
Second, it can do constant work on the final test results.
After the construction of each car, all aspects of its performance must be tested. When all the tests are qualified, it can be sold from the factory. For many aspects of automobile inspection, the inspection of the gantry-type three-coordinate measuring instrument is inseparable. For example, whether the parts inside the car can work normally, etc. As for the detection of automobiles, it should be said that it is a more critical matter, because after the unqualified automobiles are put into the market, they may cause personal injury to the drivers of the automobiles. In order to effectively avoid the occurrence of this phenomenon, it is necessary to use the gantry-type three-coordinate to monitor the various components.
