Dual milling cutter construction for full-automatic dynamic balance machine

Abstract

The invention discloses a double milling cutter structure of a full-automatic dynamic balancing machine indicating machine, which comprises a base with an insulating plate at one side, wherein, two ends of the base are respectively provided with a bearing retainer cup with a rolling bearing and an end closure playing a role in sealing; a drive cutting shaft and a driven cutting shaft supported on the base by the rolling bearing, wherein the drive cutting shaft and the driven cutting shaft transmit movement by a pair of externally engaged gears; two ends of the drive cutting shaft are respectively provided with a belt wheel and a milling cutter; one end of the driven cutting shaft is provided with a milling cutter; the end that the driven cutting shaft is provided with the milling cutter and the end that the drive cutting shaft is provided with the milling cutter are arranged at the same side; the side of the drive cutting shaft and the cutting driven shaft provided with the milling cutters extends outside the insulating plate; and one side of the belt wheel of the base is provided with a carbon brush holder used for positioning a cutting point. Drive of the belt wheel of the motor realizes that two ends of a rotor are respectively cut by a pair of reversely rotating milling cutters so as to ensure precision of running balance. The dynamic balancing machine with the double milling cutter structure has simple motion control, saves cost, and simultaneously ensures efficiency.

Description

technical field [0001] The invention relates to a double milling cutter of a fully automatic dynamic balancing machine. Background technique [0002] Power tools are important production and daily necessities. Among them, due to the influence of materials, manufacturing process and assembly, there is an unbalanced amount in the rotor. Therefore, when the rotor rotates, it will vibrate, which will bring noise, shorten product life and other adverse effects, and even bring danger. Therefore, the rotor must be dynamically balanced. [0003] In the production of electric tools, the calibration equipment for rotor dynamic balance can be divided into two categories, namely manual calibration dynamic balancing machine and automatic dynamic balancing machine. The cost of manually correcting the dynamic balancing machine is low, but the production efficiency is low. At the same time, the balancing process depends on the experience of the workers. The balancing accuracy is not high,...

Problems solved by technology

However, since the two milling cutters are independent, two sets of milling cutter slides and control devices are required, which increases the high cost

The most important thing is that the double-knife structure puts forward very high requirements on the program control. Once the program goes wrong and the tool collides, it will destroy the entire milling cutter slide table and even the entire dynamic balancing machine.

The rotor rotation method has a great advantage in cost because only one milling cutter moving slide is needed. However, since the rotor rotates through 180 degrees, the positioning device is very demanding, otherwise the cutting position will be lost, and the dynamic balance position needs to be re-checked , seriously affecting the efficiency of
