Self-electricity-generating laser positioning device of aperture processing machine

Abstract

The invention discloses a self-generating laser positioning device for pore manufacture machine. Wherein, the pore manufacture machine comprises a headstock, a motor, and dive pulley; fixing two laser emitters under the headstock that emit plane beam downward with intersection line superposition to main axis center. The laser emitters connect to induced current coil for power; the later comprises two coils fixed on end cap of motor, an iron core fixed in coil, and two permanent magnets fixed on bottom edge of dive pulley; the fix distance of coil and permanent magnet is equal. The magnet and dive pulley is linked by a copper piece; wherein, the coils and permanent magnets are distributed along concentric circles of same radius. This invention has well effect for conservation of energy; the laser emitter has enough power supply; the operation is easy and convenient. The invention has widely application fields.

Description

technical field [0001] The invention belongs to the technical field of hole processing machinery, and more specifically relates to the design of a self-generating laser positioning device for hole processing machinery. Background technique [0002] So far, the laser positioning devices of hole processing machines have been rectified and filtered by alternating current to direct current or powered by batteries. The Chinese patent with the patent number 03206244.3 and the name "Laser Auxiliary Center Alignment Device for Drilling Machine" adopts the latter Solution. This solution fixes two lasers on the drill chuck, and the drill chuck rotates when it is working, so it is difficult to be powered by AC power, so it has to be powered by batteries. The laser beam emitted by each laser also rotates accordingly, and forms a very dazzling rotating body, which seriously interferes with the operator's observation and operation, and actually cannot form a clear laser auxiliary center. ...

[0002] So far, the laser positioning devices of hole processing machines have been rectified and filtered by alternating current to direct current or powered by batteries. The Chinese patent with the patent number 03206244.3 and the name "Laser Auxiliary Center Alignment Device for Drilling Machine" adopts the latter Solution. This solution fixes two lasers on the drill chuck, and the drill chuck rotates when it is working, so it is difficult to be powered by AC power, so it has to be powered by batteries. The laser beam emitted by each laser also rotates accordingly, and forms a very dazzling rotating body, which seriously interferes with the operator's observation and operation, and actually cannot form a clear laser auxiliary center.

[0003] The applicant's recent patent application No. 200510043979.1 titled "Self-powered laser positioning device for hole processing machinery" provided a self-powered laser positioning device for the first time. But its permanent magnetic steel is fixed on the drill chuck. There are two disadvantages: the rotation speed of the main shaft and the drill chuck often changes, and the generated current is sometimes high and sometimes low, and the power supply of the laser transmitter is sometimes insufficient; the drill chuck is produced by a special factory and is replaceable. Products, permanent magnetic steel must be pasted on every drill chuck purchased, which is quite troublesome.
