Abstract

An improved disk cutter or saw laser locator structure is provided with a laser locator on the axle center of a disk cutter or saw driven by a motor, wherein the laser locator consists of a rotary disc and a static disc which share the same axle, a coil is arranged on the axle center of the rotary disc, a magnet ring is arranged on the axle center of the static disc, the magnet ring is concentric with the coil and is relatively arranged outside the coil, and the coil is connected with a laser module arranged on the rotary disc; a sedentary protective cover is arranged outside the disc cutter or saw, a pin penetrating the protective cover is inserted into the static disc to fix the static disc, while the rotary disc has to rotate with the disc cutter or saw, and consequently the magnet ring and the coil make relative movement to generate power for the laser module. The utility model overcomes well-known technical defects and avoids trouble and inconvenience of replacing a battery. In addition, the utility model does not need a switch, thereby avoiding loose contact or damage caused by the switch.

Description

The laser locator structure of improved cutting disc or saw

Technical field

The utility model relates to a kind of laser locator structure, especially refer to a kind of improved cutting disc of forming by rotating disk and inactive order or the laser locator structure of saw, be equiped with a coil and ring magnet on this rotating disk and the inactive order respectively, its relative motion and generate electricity and supply with a required power supply of laser module that is located on the rotating disk can be exempted the trouble and inconvenience of the battery that changes the outfit.

Background technology

At present, known cutting disc or saw are when cutting off bar or cutting plate, and normally after line on bar or the plate, the mode with range estimation makes cutting disc or saw in the rotation rely on line place again, thereby bar is cut off or cut plate.

The mode of above-mentioned range estimation is not easy to aim at line place, can cause oversize or too small after cutting, excessively still can repair size again, too smallly then can't retrieve; Therefore installing one laser locator on cutting disc or saw can be desired line place that cuts by the laser alignment that laser locator sent, and so can be convenient to cut.

And known laser locator, as shown in Figure 2, be equiped with a plurality of battery b in a chassis a, this battery b contact a switch C and laser module d, and this chassis a can coaxially be installed on cutting disc or the saw e, making cutting disc or saw e can drive chassis a synchronously when rotating rotates, and make switch C by the centrifugal force conducting, so can make laser module d emission light beam, and owing to laser module d is installed on the circumference of chassis a, and this chassis a makes the light beam of point-like may be extended to wire in rotation, so can be undertaken line by the light beam of wire.

Right known laser locator must use battery b, because the suitable power consumption of laser module d, so must change battery b often, thereby cause trouble and inconvenience in the work.

Moreover this switch c makes the contact of this switch C open often or close by the mode conducting of centrifugal force, is easier to damage.

The design people has above-mentioned defective thoughts on known laser locator, thereby sets about design, develops the laser locator structure of a kind of improved cutting disc or saw finally.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of laser locator that is installed on cutting disc or the saw is provided, it is made up of rotating disk and inactive order, and on rotating disk and inactive order, be equiped with a coil and ring magnet respectively, its relative motion can be generated electricity, required power supply is provided for the laser module that is located on the rotating disk, can exempts the trouble and inconvenience of the battery that changes the outfit.

Technical solution of the present utility model is: the laser locator structure of a kind of improved cutting disc or saw, on the axle center of cutting disc that a motor drives or saw, be equiped with a laser locator, wherein,

This laser locator is made up of the rotating disk and the inactive order of a coaxial installing, on the axle center of this rotating disk, be equiped with a coil, be equiped with a ring magnet on the axle center of this inactive order, this ring magnet is located at the coil outside with one heart relatively, and this coil connects a laser module that is located on the rotating disk; Outside above-mentioned cutting disc or saw, be provided with a fixed protective cover, wear a latch on this protective cover, this latch interts on inactive order, fixes this inactive order, rotating disk is along with cutting disc or saw rotate, and ring magnet and coil relative motion can be generated electricity and be supplied with the required power supply of laser module.

The utility model has the advantages that: the improved cutting disc that the utility model proposes or the laser locator structure of saw, its coil and ring magnet relative motion can produce electric current and directly supply with the laser module, needn't use battery, have exempted the trouble and inconvenience of changing battery.In addition, rotating disk is to rotate synchronously with cutting disc, and this cutting disc or saw rotate and promptly produce electric current, so needn't use switch, has avoided using in the known technology switch to cause the situation of loose contact or damage easily.

Description of drawings

Fig. 1 is an assembling view of the present utility model;

Fig. 2 is known assembling vertical view.

Drawing reference numeral explanation: 1, motor 2, cutting disc or saw 21, axle center 3, laser locator 31, rotating disk 32, inactive order 33, coil 34, ring magnet 35, laser module 4, protective cover 5, latch

The specific embodiment

For making the utility model clear and definite more full and accurate, cooperate following accompanying drawing to describe in detail now as the back:

At first, see also Fig. 1, the utility model is in the cutting disc that a motor 1 drives or saws on 2 the axle center 21 and be equiped with a laser locator 3.Wherein, this laser locator 3 is made up of the rotating disk 31 and the inactive order 32 of a coaxial installing, is equiped with a coil 33 on the axle center of this rotating disk 31.Be equiped with a ring magnet 34 on the axle center of this inactive order 32, this ring magnet 34 is located at coil 33 outsides with one heart relatively, and this coil 33 connects a laser module 35 that is located on the rotating disk 31.In above-mentioned cutting disc or saw and be provided with a fixed protective cover 4 outside 2, on this protective cover 4, wear a latch 5, this latch 5 interts on inactive order 32, this inactive order 32 is maintained static, and rotating disk 31 can or be sawed 2 rotations along with cutting disc, make ring magnet 34 with coil 33 relative motions and generate electricity, supply with the required power supply of laser module 35.

According to above-mentioned structure, because the rotating disk 31 of this laser locator 3 is along with cutting disc or saw 2 rotations, and this inactive order 32 maintains static, the coil 33 that is installed on the axle center of rotating disk 31 can rotate synchronously, make this coil 33 to produce relative motions with the ring magnet 34 on the axle center of inactive order 32, make coil 33 can produce electric current, and because these laser module 35 connecting coils 33, so can when coil 33 and ring magnet 34 caused by relative motion electric currents, make laser module 35 emission light beams, and make the light beam of point-like pull into wire, so be convenient to aim at line place on the cropped thing.

And owing to supply with the mode of laser module 35 required electric energy, be directly to supply laser module 35 by the electric current that coil 33 and ring magnet 34 relative motions are produced, therefore exempted the trouble and inconvenience of using battery and must changing battery.

In addition, the rotating disk 31 of this laser locator 3 is along with cutting disc or saw 2 and rotate synchronously, so this cutting disc or saw 2 and produce electric energy when rotating and supply with laser module 35, causes the situation of loose contact or damage easily so must use switch in the no known configurations.
