How To Use The Coordinate Measuring Fixture
- Aug 24, 2017 -

Coordinate measuring fixture referred to as the three-coordinate fixture, also known as the coordinates of the universal fixture or three coordinate flexible fixture, coordinate measuring instrument is the use of fixture modular support and its reference device, the measured parts for flexible fixation. The use of coordinate measuring fixtures can fix and clamp any parts of a complex face, minimizing the error of the measurement and ensuring the accuracy of the measurement.

As we all know, in the coordinate work platform can not be directly measured, it is necessary to use some specific coordinate measuring fixture to complete the measurement work, CMM Holding Fixtures because the main body of the three clamping fixture is a flat plate, so as to avoid clamping on the platform repeated friction, Can play a role in protecting the working platform of the coordinate measuring instrument, the use of coordinate measuring fixture can also extend the service life of the machine. At work, CMM Holding Fixtures the fixture as long as through the ever-changing combination, you can achieve the coordinate measuring instrument in the measurement of a variety of fixture needs.

So what is the use of coordinate measuring fixture? Let's take a brief look at the following. To determine the bottom of the measured part of the shape, to select the specific type of fixture, CMM Holding Fixtures and then the workpiece will be supported on the bottom plate, and then select some of the fixture used to tighten the fixture selection depends on the side shape of the parts to make it Tightly fixed on the floor, CMM Holding Fixtures so that when the machine is working to improve the detection accuracy.

In fact, each hole and fixture of the mounting plate are code-named, we can put them in any combination of the combination of code to write down, in our next repeat measurement products, as long as the components of the recording fixture installed on the platform, On the measured parts, you can measure.

Now the continuous progress of science and technology, people on the mechanical production parts of the accuracy requirements are getting higher and higher. In fact, CMM Holding Fixtures the accuracy of the test results from the measuring instrument itself performance and measurement methods, more inseparable from the use of coordinate measuring fixture. Coordinate measuring instrument every part is subject to rigorous testing to ensure that can be more accurate.

Coordinate measuring machine working platform that is granite platform, but in this platform can not be fully measured, but also need to use some coordinate measuring fixture to fully measure, CMM Holding Fixtures in recent years, CNC machine tools, machining centers, group technology , Flexible manufacturing system (FMS) and other new processing technology applications, the three coordinate measuring fixture made the following new requirements:

coordinate measuring fixture can quickly and easily equipped with new products put into production, CMM Holding Fixtures in order to shorten the production preparation cycle, CMM Holding Fixtures reduce production costs;

The coordinate measuring fixture can be fitted with a set of workpieces with similarity characteristics;

can be applied to precision machining of high-precision machine tool fixture;

can be applied to a variety of modern manufacturing technology of the new machine fixture;

coordinate measuring fixture with hydraulic station as the power source of the efficient clamping device to further reduce the labor intensity and improve labor productivity;

Increase the degree of standardization of the coordinate measuring fixture.
