Description

Encoder counting wheel circumference calibrating device Technical Field The utility model relates to the field of section bar feeding devices, in particular to a device for calibrating the circumference of a counting wheel of an encoder. Background In the encoder feedback feeding mechanism, the circumference of the counting wheel of the encoder is the most critical parameter, and the accuracy of material feeding is directly affected. The actual circumference of the encoder counter wheel changes slightly due to temperature and wear, dirt, etc., and the small changes have a relatively large effect on the mapping of the encoder to the actual distance. Often, the circumference of the encoder count wheel needs to be re-entered over time or at the time of replacement of the count wheel. This re-entry procedure, which is in fact a calibration procedure, requires re-detection and calculation. The conventional or previous calibration process is manually completed, the efficiency is low, the workload is high, the production is inaccurately and seriously influenced, the practicability of the whole mechanism is also adversely influenced, the feeding mechanism is firstly enabled to feed, the position before feeding is recorded, after a certain distance is fed, the position after feeding is recorded, the distance between the front position and the rear position is measured, the number of turns rotated by the encoder is calculated according to the circumference of the previous encoder, and the distance is divided by the number of turns to be equal to the actual circumference of the counting wheel. The process requires mechanical actions such as sawing and cutting or drilling, and is used for imprinting on materials, and relatively large errors exist in measurement, two persons are required to complete the action, waste exists in the materials, the efficiency is low, the actions are more, and workers are required to be familiar with the method and how to calculate, so that the process is relatively complex.
