Description

Tool machine angle positioning measurement system

This creation is about a measuring device for measuring the rotation axis of a machine tool. Specifically, it is a simple machine tool angle positioning measurement system, which can greatly reduce the measurement cost and can effectively improve the accuracy of measurement.

In recent years, due to the development of micro-machining and the improvement of precision requirements, the requirements for the angular positioning accuracy of the rotating shaft of the machine tool are also increasing. However, since the angular measurement of the rotating shaft directly affects the positioning accuracy, the machine tool rotates. It is important that the measurement technique of the shaft angular positioning is sufficient to meet its accuracy requirements. At present, there are two commonly used instruments for detecting angular positioning, one of which is an automatic collimator and the other is a laser interferometer.

In terms of the detection of the automatic collimator, the automatic collimator mainly measures the small angle, and then measures the angular position, and works with the extremely small angle principle generated by the measuring light source through the plane mirror, and cooperates with the multi-faceted cymbal and the measurable rotating shaft. Angle positioning error. However, although the automatic collimator is relatively simple and low in cost, its measurement accuracy cannot fully meet the needs of current micromachining.

In terms of the detection of the laser interferometer, the laser interferometer is the most reliable measuring device in the industry when testing the performance of the machine. The angle of the angle mirror group and its optical path reflection can be different by laser interference. The processor of the instrument measures small angle changes. However, the laser interferometer itself and its associated mirror set are very expensive. Expensive, and pay attention to whether the light source is shielded when the measurement process takes time. When the light source is shielded, the laser interferometer signal must be reset.

In other words, the development of lower cost, simple and convenient measurement technology, and the need for precision, is an important issue in the industry, and it is necessary to further develop to meet the needs of actual use.
