Burr removing machining method based on torque control and burr removing system

Abstract

The invention provides a burr removing machining method based on torque control and a burr removing system. The burr removing system comprises a pushing mechanism, a burr removing mechanism with a motor, a torque sensor, a torque amplifier and a controller with a body and an analog-digital converter. The burr removing machining method comprises the steps that a run program is written into the body, and a standard threshold value is set in advance; a burr removing tool is driven by the pushing mechanism according to the run program to move to a workpiece; the current load torque of the motor isdetected through the torque sensor, the current load torque is converted into standard analog signals through the torque amplifier, and the standard analog signals are converted into digital currentsignals through the analog-digital converter; and the digital current signals are obtained by the body, the standard threshold value is compared with the digital current signals, and the feeding amount of the pushing mechanism is adjusted according to the comparative result. By means of the burr removing device and the burr removing machining method, the burr removing tool feeding amount can be adjusted according to friction force borne by the burr removing tool, and the beneficial effects of being high in machining accuracy and good in machining quality are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a torque control-based deburring processing method and a deburring system applying the method. Background technique [0002] During the milling, turning, drilling and other mechanical processing of products, the processed parts are often prone to burrs and flashes, which not only affect the surface quality of the parts, but also affect the performance of the parts. The traditional processing method is to deburr the parts manually, but the manual processing method has disadvantages such as low production efficiency and high labor intensity. Therefore, many companies are gradually beginning to use mechanical equipment to replace the traditional manual processing of parts. Perform deburring treatment to improve production efficiency and deburring accuracy of parts, and ensure the quality of parts. [0003] The deburring equipment currently on the market generally uses...

Problems solved by technology

Although the propulsion method of the propulsion mechanism can also complete the deburring treatment on the surface of the part, this kind of propulsion method is not intelligent enough, so that when the blank size of the workpiece has a large tolerance range, the propulsion mechanism cannot automatically adjust the size of the part The feed rate during the movement of the deburring tool not only affects the processing accuracy of the part, but also easily causes a strong collision between the deburring tool and the part at the beginning of contact, which makes the deburring tool or the part easy to be damaged

In addition, the existing deburring equipment is still unable to accurately compensate the wear of the deburring tool. The wear compensation of the deburring tool can only be adjusted through the work experience of the equipment designer, which reduces the machining accuracy and processing quality of the parts. quality
