In order to ensure the accuracy of the position of the machined surface or the surface of the surface to be tested relative to the other surfaces, it is first necessary to have the workpiece on the machine tool in order to ensure that the work of the coordinate surface is very important. Accurate position, and in the process of processing or testing, to withstand the role of various forces and always maintain this position unchanged. CMM Holding Fixtures The former for the workpiece positioning, which is the workpiece clamping. The whole process is collectively referred to as the clamping of the workpiece. The process equipment used to mount the workpiece on three coordinates is called a coordinate measuring fixture.
As we all know, the coordinate measuring machine working platform that 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, into 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, 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;
Increases the standardization of the coordinate measuring fixture.
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. CMM Holding Fixtures The use of a coordinate measuring fixture can fix and clamp any parts of a complex surface, minimizing the error of the measurement and ensuring the accuracy of the measurement.
As we all know, in the three-coordinate work platform can not be directly measured, CMM Holding Fixtures it is necessary to use some specific coordinate measuring fixture to complete the measurement work, because the main body of the coordinate fixture is a clamping plate, so as to avoid the fixture on the platform repeated friction , CMM Holding Fixtures 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. In the work, 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 the coordinate measuring tool holder? Let us 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 of the workpiece, and then to choose 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, in order to improve the detection accuracy of the machine when working.
In fact, each hole and fixture of the mounting plate are code-named, we can put them in any combination of the combination code to write down, in our next repeat measurement products, CMM Holding Fixtures 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, the accuracy of the test results from the measurement instrument itself, the performance and measurement methods, CMM Holding Fixtures more inseparable from the use of coordinate measuring fixture. Si Rui coordinate measuring instrument every part is subject to rigorous testing to ensure that can be more accurate.
