The present invention utilizes the rotation of the motor to generate the electricity automatically; therefore, the present invention has the advantages of good effect of energy saving, sufficient power supply of the laser transmitters, and simple and convenient operation and manufacture; furthermore, the present invention can be widely used for various aperture processing machines, such as, table drills, vertical drills, lathes, etc.
Description
Technical field
The invention belongs to the aperture processing machine technical field, more particularly relate to the design of the self-electricity-generating laser positioning device of aperture processing machine.
Background technology
Up to now, the laser locating apparatus of aperture processing machine is direct current or battery-powered by alternating current through rectifying and wave-filtering. the patent No. is 03206244.3, the Chinese patent that name is called " drilling machine laser sectional center alignment device " has just adopted back a kind of scheme. and this scheme is fixed on two laser instruments on the drill chuck, and drill chuck work the time is rotated, be difficult to by AC-powered, have to battery-powered. but because of it laser instrument is fixed on the drill chuck, two also corresponding rotations of the laser beam that laser instrument sent during work, and form a revolving body of very dazzling the eyes, serious perturbation operation person's observation and operation can not constitute clearly laser sectional center in fact.
The patent application that the applicant's No. 200510043979.1 names not long ago are called " self-supply laser positioner of aperture processing machine " provides a kind of self-powered laser locating apparatus for the first time. but its permanent-magnet steel is fixed on the drill chuck. and this just exists two deficiencies: the rotating speed of main shaft and drill chuck often changes, generate electricity stream also with regard to the time low when high, deficiency is arranged during the power supply of generating laser; Drill chuck is produced by special factory, belongs to replaceable product again, must all paste permanent-magnet steel on each drill chuck of buying, quite trouble.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of self-electricity-generating laser positioning device of aperture processing machine is provided. and it utilizes the rotation self power generation of motor, without alternating current and battery, thereby good energy-conserving effect; Rotating speed of motor is constant, the stream that generates electricity also just constant, it is sufficient that the power supply of generating laser keeps; Need on drill chuck, not paste permanent-magnet steel, more need not change, operate, make simple and convenient.
Aperture processing machine comprises main spindle box, be fixed on the motor on the main spindle box and be fixed on motor the axle on parts such as drive pulley. fixing two generating lasers below the main spindle box, two generating lasers send planar light beam respectively downwards, and the intersection of two planar light beams overlaps with the center of main shaft. and two generating lasers are connected power supply with the induced current coil. and the induced current coil comprises the coil on the end cap that is fixed on motor, be fixed on the iron core in the coil, being fixed on the permanent magnet on the drive pulley lower edge. the fixed position of coil and permanent magnet equates apart from the distance of electrical axis.
During work, motor maintains static, motor shaft and the drive pulley of fixing on it rotate at a high speed with respect to motor. therefore, the coil that is fixed on the electric motor end cap constantly cuts the magnetic field that is fixed on the permanent magnet on the drive pulley, will induce induced current in the coil and supply with generating laser. the magnetic field superposition that the iron core in the coil induces can strengthen induced current on the magnetic field of permanent magnet.
Between permanent magnet and the drive pulley with the copper sheet fixed bonding. when drive pulley is that aluminium alloy is when making, permanent magnet also can directly be bonded on the drive pulley, because aluminium alloy is a nonmagnetic substance. when drive pulley was the cast iron making, copper sheet can be avoided the field weakening that magnet short-cut path caused between permanent magnet and the drive pulley.
Coil and permanent magnet can respectively have two, and they are uniform along the identical concentric circles of radius respectively. and this relatively simple for structure, and can produce enough electric currents and power to generating laser.
Task of the present invention comes to this and finishes.
The invention provides a kind of self-electricity-generating laser positioning device of aperture processing machine. it utilizes the rotation self power generation of motor, without alternating current and battery, thereby good energy-conserving effect; Rotating speed of motor is constant, the stream that generates electricity also just constant, it is sufficient that the power supply of generating laser keeps; Need on drill chuck, not paste permanent-magnet steel, more need not change, operate, make simple and convenient. it can be widely used in the aperture processing machines such as various bench drills, vertical drill, lathe.
