Single-power and dual-drive reciprocating brush device

Abstract

The invention provides a single-power and dual-drive reciprocating brush device. The single-power and dual-drive reciprocating brush device comprises a brush, a brush drive mechanism and a position adjustment mechanism. The brush drive mechanism provides working power for the brush. The position adjustment mechanism can conduct adjustment and drives the brush drive mechanism to move so that the position and stroke of the brush can be adjusted. The brush drive mechanism comprises a motor, a synchronous drive mechanism and an adjustable eccentric cam mechanism. The position adjustment mechanism comprises a height adjustment mechanism and a stroke adjustment mechanism. The brush drive mechanism is connected with the position adjustment mechanism through a fixed plate. By means of an adjustment threaded rod of an adjustable eccentric cam shaft, the front and back displacement and the stroke of the brush device can be adjusted, accurate positioning and reciprocating displacement can be achieved, the synchronous driving of the brush and displacement can be achieved, synchronization and different speeds are achieved through two driven devices, the starting time and the rotating speed are accurately controlled through control of a PLC automatic control system and a series of valves, and the precise displacement of the brush device and the adjustment of the rotating speed are achieved with low cost.

Description

technical field [0001] The invention relates to a processing machine, in particular to a reciprocating brush device. Background technique [0002] The brush device is a device that quickly removes debris such as shavings and other debris accumulated on the surface of the workpiece and in the groove through the reciprocating motion of the brush on the surface of the workpiece at high speed. This kind of dandruff removal method is called a brush dandruff removal device. The brush dandruff removal device has the characteristics of high production efficiency, low cost, material saving, and easy automatic control. Therefore, it is widely used in various industries such as energy, electronics, automobiles, and light industry. Sector is one of the important anti-dandruff processes. The quality of the brush dandruff removal device is generally determined by the following three variables: (1) brush material; (2) brush rotation speed; (3) whether it moves back and forth. In addition...

Problems solved by technology

[0005] 1. The disadvantage of manually moving the brush wheel (generally hand-held) through a mechanical device to clamp the workpiece is that the work efficiency is low, and the second is that the strength of the human device varies from person to person and from time to time, resulting in inconsistency between the brush wheel and the workpiece. , resulting in unstable brushing quality

[0006] 2. Generally, it is not accurate enough to use the cylinder-driven mechanical device to move the motor to drive the brush wheel to brush the workpiece. The efficiency is low during the reciprocating process, and obvious impact vibration is generated. The workpiece is easy to fall during the brushing process, and it is easy to Cause workpiece deformation, which is not allowed for many brushed workpieces, such as the brushing of the inner rotor commutator of the motor on the electric tool; two motors are used to drive the brush wheel and reciprocating motion respectively, due to two The movement of the motors is not easy to achieve synchronization, and it is easy to cause invalid work or invalid reciprocating motion of the brush wheel, and the other two motors generate excessive energy consumption, which does not meet the requirements of energy conservation and environmental protection

[0007] 3. The main disadvantage of the brushing device using the servo motor to drive the brush wheel is that it is expensive

Since the servo motor produces static torque, once an abnormality occurs, the workpiece will be thrown away by the constant torque output by the servo motor lock, even if the blocked motor may be damaged or abnormal, and cause damage to the workpiece
