A Control System of Measuring Belt Length Device

Abstract

The invention discloses a control system for a belt length measuring device, which includes a touch display screen, a controller, a fixed pile, a slide table, a motor and a sensor. Input the measurement command, the controller controls the motor to drive the sliding table to move, the motor output current detection module detects the output current of the motor, and its output terminal is connected to the comparison module, the comparison module has a built-in benchmark threshold value of the motor current, and the sliding table torque detection module detects the sliding table. The output end of the platform torque is connected to another comparison module, which has a built-in reference threshold value of the slide table torque. The controller controls the forward and reverse rotation of the motor according to the output result of the comparison module. If it is greater than the reference threshold value, it stops the motor and passes the sensor Record the current length between the sliding platform and the fixed column. If it is less than the reference threshold, the motor will continue to rotate. The present invention uses digital automation to realize automatic measurement and reduce errors under the condition that the belt is stretched.

Description

technical field [0001] The invention relates to a machine tool belt length measuring device, in particular to a control system for the belt length measuring device. Background technique [0002] Industrial belts, as the name suggests, are belts used in industry. According to different uses and structures, they can be divided into various categories. Compared with gear transmission and chain transmission, industrial belt transmission has the advantages of simple mechanism, low noise and low equipment cost, and is widely used in various power transmissions. The three major types of industrial belts, industrial transmission belts, automotive transmission belts and conveyor belts, are used in different places because of their different characteristics. [0003] (1) Industrial transmission belt: The transmission belt is mainly used for electromechanical equipment, which is driven by the power generated by the motor. Common precision machinery industries such as home appliances,...

Problems solved by technology

[0006] The disadvantages of the prior art are: for industrial applications, the accuracy of the belt length is very high when used in groups, and the current measurement of the belt length is basically based on manual naked eye measurement, so there is a large error; and the belt is actually It needs to bear a certain tension during use, and the traditional manual measurement method cannot meet the requirements
