Optimization method of cutting zero point positioning of automatic balancing machine and its auxiliary circuit

Abstract

The invention discloses a method of optimizing cutting zero point location of a full automatic balancing machine. The method comprises the following steps of (1) preparing a machine tool, (2) feeding a tool, (3) filtering and shaping, and (4) judging the tool. In particular, the cutting zero point location is judged through judging whether the contact frequency of blades of the tool and a product is consistent to the number of blades in the time that the tool rotates for a circle while the delay operation is performed. The invention also discloses an auxiliary circuit applied to the method. The auxiliary circuit comprises a low-pass filter circuit, a high-level clamping module, a phase reversing module and a judging module, wherein one end of the low-pass filter circuit is connected to an electric conduction part, the other end of the low-pass filter circuit is connected to the phase reversing module, the high-level clamping module is connected between the low-pass filter circuit and the phase reversing module in parallel, the phase reversing module is connected to the judging module through a transition module, and the other end of the judging module is connected to a programmer. According to the method, cutting zero point location of the balancing machine is optimized, so that accuracy for the cutting zero point location of the balancing machine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment control, in particular to a cutting zero point positioning optimization method of a fully automatic balancing machine and an auxiliary circuit thereof. Background technique [0002] The motor is an important production and daily necessities. During the manufacturing process of the motor rotor, due to the influence of the material, manufacturing process and assembly, there is an initial unbalance. Vibration and noise shorten the life of the product and even bring danger. Therefore, it is necessary to correct the dynamic balance of the motor rotor. [0003] With the development of science and technology, the correction of the motor rotor has changed from the manual correction of the transmission to the mechanical automatic correction. At present, the balance machine is generally used to perform mechanical correction on the electronic rotor to improve the correction accuracy of the rotor...

Problems solved by technology

[0005] However, the above method directly inputs the high and low level signals from the contact (i.e. a conductive part) into the single chip microcomputer for judgment, and may introduce the low level signal caused by iron filings into the single chip microcomputer, thus causing misjudgment of positioning; moreover, in the motor During the corrected cutting process of the rotor, it is inevitable that the first cut is not qualified and the position of the second cut overlaps with the position of the first cut. The tool rotates at a constant speed, so the traditional delay positioning method is prone to insufficient delay time, that is, the contact time between the milling cutter and the rotor is shorter than the delay time, which leads to inaccurate positioning
