The linear module is a relatively changeable product which is suitable for many industries, and it is also suitable for many environments. It is a relatively comprehensive linear motion device. The linear module is a very precise automatic mechanical equipment. In practice, we should strictly grasp the specific accuracy and measure the accuracy when necessary. The accuracy of linear modules can usually be measured by the following methods.
Method 1: When measuring positioning accuracy and linear module accuracy, the maximum stroke is taken as the reference length, and then the linear module accuracy is indicated by the absolute value of the maximum error between the interval from the reference orientation to the actual movement and the instruction value.
Method 2: Repeated positioning accuracy Repeat positioning of any point on the linear module in the same direction for many times, and then measure its stop position. Detect the positions at the center and roughly two ends of the moving interval, take the maximum value in the inspection value as the measured value, and mark it with half of the maximum difference between positive and negative.
Method 3: Working Parallelism: Place a standard ruler on the high-quality linear module platform, and measure and check the accuracy of the linear module with the scale limit that the experimental indicator can move within the inner slider.
Method 4: To measure the accuracy of the clearance linear module, the inner slider should be fed first, and the reading of the experimental indicator when the slider just moved is taken as the benchmark. As a preliminary result, the micro electric steel exerts a load in the same direction as the moving direction of the inner slider without depending on the feeding equipment, and then the difference between the initial reference value and the orientation when it comes back is taken as the measured value. The accuracy inspection of the linear module is carried out at the center of the moving part and the azimuth of the two ends, and the maximum value of the obtained values is taken as the measured value.
The measurement method of the accuracy of the linear module should choose the appropriate measurement method according to the actual application scenario, and at the same time, the influence of the accuracy error, installation error, use environment and other factors on the linear module should be considered. In the process of measurement, it is necessary to pay attention to the use of correct measuring tools and methods, abide by measuring standards and norms, and avoid subjective assumptions and error transmission. At the same time, we need to pay attention to the maintenance of the linear module, adjust and correct the errors in time, and ensure the accuracy and use effect of the linear module.
