How to solve the instability of the pointer of the coordinate measuring machine? Published: 2019-12-04 Source: https://www.microaccuracy.com/ The three coordinate measuring machine adopts a contact measurement method, and the pointer is an important aspect of the device contact measurement, but the stability of the measurement pointer is much affected. The instability of the pointer will directly affect the measurement effect. How to solve the instability of the pointer of the coordinate measuring machine? There are many situations that cause the pointer of the coordinate measuring machine to be unstable, and the corresponding solutions should be adopted according to different actual situations: unstable friction: such as the pointer, the pendulum bearing is not flexible, and the working piston and the force measuring piston have friction. It can be carefully inspected, cleaned and trimmed to eliminate friction and troubleshoot. Buffer valve spring failure: caused by the failure of the buffer valve spring of the coordinate measuring machine, the solution is to replace the spring with a new one. Belt falling off: The belt driving the rotation of the force measuring piston of the coordinate measuring machine falls off, and the belt can be re-attached at this time. Oil viscosity: The oil viscosity of the three-coordinate measuring machine is too large, and the oil with suitable viscosity needs to be replaced to eliminate the fault. Poor meshing: poor meshing between the gear rod and gear of the coordinate measuring machine or the contact between the gear rod and the spring sheet above can be eliminated by adjusting the meshing between the gear rod and the gear and the position of the spring sheet. The guide wheel rubs against the column: The guide wheel on the workbench of the coordinate measuring machine rubs against the column. The gap between the guide wheel and the column can be adjusted to maintain a gap of about 0.5mm to eliminate the fault. The above is the common situation that causes the pointer of the coordinate measuring machine to be unstable. The solution can be effectively processed by taking the above-mentioned measures according to the corresponding situation. Correct operation and use can bring better measurement accuracy to the equipment.
