The CMM fixture is referred to as the three coordinate fixture, also known as the three coordinate universal fixture or the three coordinate flexible fixture. It is generated to meet the needs of the CMM to collect point data from different directions and place the workpiece.
CMM can collect data of workpiece in three-dimensional space. It is a precision instrument for calculating the geometric shape and size of workpiece through professional software system. The working platform of CMM is generally granite. When testing, the workpiece is placed on the platform, and the measuring head of the measuring machine collects the point data of the workpiece from different directions. However, the workpiece needs to be fixed when it is placed. Therefore, CMM fixture came into being. According to the different materials processed, the durability, accuracy and stability of the three coordinate fixture vary greatly. Processing technology is also very important. The fixture with good technology can play a stable role, and at the same time, it will not cause wear to the workpiece. At present, there are many manufacturers and suppliers of CMM in China. It is necessary to choose a suitable jig for your CMM.
The jig of CMM can quickly, conveniently and stably clamp the tested workpiece. The utility model can effectively complete the fixing and clamping of workpieces with various complex profiles. Minimize measurement error and ensure measurement accuracy.
Three coordinate fixture is divided into base, various supports and plungers, fastening screws and compression blocks. Through different combinations, various workpieces and parts can be fixed. The measuring head of CMM can collect data from the workpiece in different directions. There are more than 40 pieces in a set of CMM fixtures, and hundreds more. It is generally composed of the following different tools: 1. elastic pressing plate, 2. elastic pressing plate support column, 3. fixed support block, 4. height adjustable support, 5. sliding support block, 6. base, 7. fastening screw, 8. quick clamp, 9. strong support, 10. vertical mounting frame, 11. elastic plunger, 12 universal joint, 13. universal joint base, 14. compression spring, 15. support rod, 17. pressing plate, 18. cone support, 19. operating tools, etc.
When using the three-dimensional fixture, first place the base at the correct position on the three-dimensional working platform. The fixed position of the support shall be determined according to the different shapes and testing requirements of the workpiece to be tested and fixed with the locking screws. Then place the tested workpiece on the support, and lock the workpiece with elastic pressing plate or clamp.
