Description
Technical field
The present invention relates to a kind of electric tool, specifically a kind of Electric drill depth control structure.
Background technology
Electric drill is a kind of conventional electric tool, also be the electric tool series products had the call, electric drill operation principle is that the rotor of electromagnetic rotating formula or electromagnetic reciprocating low capacity motor does magnetic field intercepts acting running, apparatus for work is driven by transmission mechanism, driven gear strengthens the power of drill bit, thus make drill bit scraping material surface, better pierce object.Traditional electric drill does not generally all have allocating and measuring electric drill to pierce the instrument of the degree of depth, and the degree of depth that therefore drill bit pierces is difficult to control, or such as when the hole needing brill one trestle column identical, traditional electric drill needs underlining, and operation also comparatively bothers.
Summary of the invention
The present invention is directed to prior art deficiency, provide a kind of Electric drill depth control structure, this kind of Electric drill depth control structure conveniently can control the degree of depth that electric drill pierces, and can improve precision, even can work as chi and use.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of Electric drill depth control structure, comprises electric drill body, described electric drill body is provided with drill bit, described electric drill body is provided with the light source that can send convection light, and the convection light of described light source injection and described drill bit are at an angle.
In technique scheme, preferably, convection light and the described drill bit of described light source injection are 45 degree, because tan45 °=1, and the distance of the movement of the length that electric drill pierces and convection light point on the wall.
In technique scheme, described light source and described electric drill body are rotationally connected, described light source is provided with pointer, described electric drill body is provided with index dial, described index dial subscript is marked with described light source injection convection light and the described drill bit angle that is, the angle making convection light and drill bit be like this can regulate, more useful for needing the drilling operation of higher precision like this, and accuracy requirement is higher more tunes up the angle that convection light and drill bit be.
In technique scheme, preferably, on described index dial, also mark has length, described length be described drill bit end points when vertically touching a plane convection light be mapped to the distance of the point in plane to described drill bit end points, make electric drill sometimes can be used as ruler use like this.
The present invention compared with prior art, has following beneficial effect:
The present invention is provided with the light source that can send convection light on electric drill body, and the movement of the point that electric drill can be mapped on machined surface according to light beam in use controls the degree of depth that electric drill pierces.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is the structural representation of the embodiment of the present invention two.
Fig. 3 is the structural representation of electric drill of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
See Fig. 1, embodiment one, a kind of Electric drill depth control structure, comprises electric drill body 1, described electric drill body 1 is provided with drill bit 2, described electric drill body 1 is provided with the light source 3 that can send convection light, at an angle, in the present embodiment, the convection light that described light source 3 penetrates and described drill bit 2 are in 45 degree for the convection light that described light source 3 penetrates and described drill bit 2, because tan45 °=1, the distance of the movement of the length that electric drill pierces and convection light point on the wall.
In use, drill bit 2 vertically pierces plane to embodiment one, and the displacement of the hot spot that convection light when piercing according to drill bit 2 in plane is formed controls the degree of depth that electric drill pierces.
See Fig. 2, embodiment two, a kind of Electric drill depth control structure, comprise electric drill body 1, described electric drill body 1 is provided with drill bit 2, described electric drill body 1 is provided with the light source 3 that can send convection light, described light source 3 is rotationally connected with described electric drill body 1, described light source 3 is provided with pointer 4, described electric drill body 1 is provided with index dial 5, described index dial 5 subscript is marked with described light source 3 and penetrates the angle that convection light and described drill bit 2 be, the angle making convection light and drill bit 2 be like this can regulate, more useful for needing the drilling operation of higher precision like this, accuracy requirement is higher more tunes up the angle that convection light and drill bit 2 be, on described index dial 5, also mark has length, described length be described drill bit 2 end points when vertically touching a plane convection light be mapped to the distance of the point in plane to described drill bit 2 end points, make electric drill sometimes can be used as ruler like this to use.
Embodiment two in use, the angle that the convection light regulating described light source 3 to penetrate and drill bit 2 are formed is x, drill bit 2 vertically pierces plane, the displacement of the hot spot that convection light when piercing according to drill bit 2 in plane is formed controls the degree of depth that electric drill pierces, the distance of the hot spot movement on wall is y, the degree of depth that then drill bit 2 pierces is cotx × y, being marked with length at index dial 5 subscript makes drill bit 2 can directly read from index dial 5 to the distance of hot spot, uses convenient.
Above-described embodiment all can be used for the operation of boring big hole, the face that will hole is determined a bit, then electric drill rotates around this point, will ensure that vertical with this face all the time and convection light of drill bit 2 is radiated on the point determined all the time simultaneously, can get out a great circle.
In a kind of Electric drill depth control structure described in above-described embodiment one and embodiment two, see accompanying drawing 3, comprise handle 6, in one end of described handle 6, battery 12 is housed, in described electric drill body 1, have the motor 7 driving drill bit 2, described motor 7 comprises output shaft 70
Also comprise body 8, cooling water is full of in described body 8, described body 8 is around motor 7 and form closed-loop path in described electric drill body 1, body 8 is provided with magnetic drives wheel 9 near inside, described output shaft 70 position, described output shaft 70 is fixedly installed permanent magnet 10 near the side of described magnetic drives wheel 9, when electric drill uses, motor output shaft 70 rotates the rotation driving permanent magnet 10, the mode transmitted by magnetic drives magnetic drives to take turns the rotation of 9, thus the cooling water in body 8 can be circulated.
The storage tank 11 for storing cooling water is provided with in described electric drill body 1, in described storage tank 11, more cooling water is set, described storage tank 11 is communicated with described body 8, so just can have the heat that enough cooling waters produce in electric drill running to absorb battery, after ensure that electric drill long-play, cooling water heat absorption is too much ineffective.
Described storage tank 11 is provided with through hole 110, the housing that electric drill body 1 corresponds to through hole 110 position can be dismantled, described through hole 110 is twisted and is provided with stubborn cap 111, in the long-time use procedure of electric drill, if desired in body 8, increase or change the words of cooling water, only need to dismantle the housing that electric drill body 1 corresponds to through hole 110 position, turn on stubborn cap 111, add in through hole 110 or pour out cooling water.
