What is the general accuracy of linear modules? How to measure its accuracy?

2021-05-12

The measurement method of each precision is different, but the measurement principle is almost the same. In short, in the actual application of the linear module, it is necessary to strictly grasp the change of precision and reduce the precision error as much as possible, so as to better utilize the equipment. stability. The accuracy of the linear module indicates the level of its performance. Now I will introduce the measurement method of the linear module:


Linear Module Accuracy


1. Positioning accuracy: take the larger stroke as the reference length, expressed by the absolute value of the larger error between the distance actually moved from the reference position and the command value;


2. Repeated positioning accuracy: 7 times of repeated positioning of any point in the same direction, and then measure its stop position, and calculate 1/2 of the larger difference of the meter reading. As a test principle, test at the center and roughly both ends of the moving distance respectively, take the larger value of the test values as the measured value, and represent it with 1/2 of the larger difference with ±;


3. Clearance: Feed the inner slider, based on the reading of the test indicator when the slider just begins to move, starting from this state, independent of the feeding device, in the same direction as the inner slider moves (The feed direction of the table) is applied, and the difference between the reference value at the start of the test and the position at the time of return is regarded as the measured value. The test is carried out at the center and roughly both ends of the moving part, and the larger value of the obtained values is regarded as the measured value;


4. Running parallelism: place a standard ruler on the platform where the linear module is installed, and use the test indicator to test within the range that the inner slider can move. The larger difference between the readings within the moving range is the measured value.
