The specific embodiment
below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 2 to Fig. 3, a kind of drilling equipment, comprise base 101, two guide pin bushings 1 have been arranged side by side on described base 101, be provided with guide pillar 10 in the interior slip of described guide pin bushing 1, be provided with tooth bar 100 on described guide pillar 10 outer walls, be provided with the gear 2 that is mated on tooth bar 100, described gear 2 is connected with rotating shaft 3, come the rotation of driven gear 2 by shaking rotating shaft 3, driven vertical movement the up and down of guide pillar 10 by the cooperation of gear 2 and tooth bar 100, therefore guide pillar 10 can not be offset in the horizontal direction.
be provided with in the end of a described guide pillar 10 for the fixing electric drill fixed mount of electric drill, during use, electric drill 7 fixing with described electric drill fixed mount on, be fixedly installed transparent cover body 4 on another described guide pillar 10, during use, cover body 4 end faces and ceiling develop, during boring, electric drill is through described cover body 4, the first light source 5 is set on the sidewall of described cover body 4, the intersection point of the light of described the first light source 5 emission and cover body 4 end planes top by electric drill, namely, during boring, the light of the first light source 5 is radiated at the electric drill top position that contacts with ceiling, also namely need the position of punching, therefore no matter be in the situation that the ceiling terrain clearance to observe indeterminacy than pork true, or in the situation that crossing dark naked eyes, ceiling light is difficult for seeing clearly, only needing with the naked eye, observation light source is radiated at the position of ceiling with regard to the position of the accurate positional punch of energy.
The lower surface of described base 101 is provided with roller 6, is convenient to adjust in use the position of base.
described guide pillar 10 comprises cylinder 8 and sleeve pipe 9, described cylinder 8 slides and is arranged in described sleeve pipe 9, offer screwed hole 90 on described cylinder 8 sidewalls, cylinder 8 is established during bolt is fixed in sleeve pipe by twisting in screwed hole 90, screwed hole 90 intervals evenly arrange, when guide pillar 10 length can't make the cover body 4 that is fixed on guide pillar 10 upper ends and electric drill touch ceiling not, can unscrew the bolt in screwed hole 90, the cylinder 8(that extracts part in sleeve pipe 9 extracts the length of cylinder 8 and is the spacing of several screwed holes 90), then the bolt of again screwing on, make cylinder 8 retighten in sleeve pipe 9, so just lengthened the length of guide pillar 10, and when electric drill stand of the present utility model does not use, cylinder 8 can stretch into sleeve pipe 9 least significant end positions, so just reduced the storage area of the utility model electric drill stand, make electric drill stand carry or carry all very convenience.
And on described electric drill 7, secondary light source 15 is set, light, drill bit and the rule 13 of described secondary light source 15 emissions are positioned at same plane.(in Fig. 4, arrow a refers to the direction that drill bit pierces referring to Fig. 4, arrow b refers to the direction of secondary light source light emission), (the α angle can regulate in advance by the angle [alpha] of secondary light source 15 and drill bit, be that α is a known angle of having adjusted) and the fashionable secondary light source light of bit drills rule inswept can fix on state as Fig. 4 apart from n(, be that drill bit rigidly connects when touching ceiling, the position of light on rule of secondary light source emission is the zero point of rule) determine that drill bit pierces the degree of depth of ceiling, be that the depth D that drill bit pierces can be obtained by equation: D=n/tan α.
Obtain a comparatively preferred angle [alpha] by above-mentioned formula, be α=45 °, this moment D=n, be that the degree of depth that pierces of drill bit identical with the distance of streaking on rule 13 (be the light of the secondary light source 1cm that slides on rule, drill bit just pierces ceiling 1cm) can mark the accurate scale of subscript this moment on rule.but the angle [alpha] of secondary light source 15 and drill bit does not limit and above-mentioned angle, the angle of increase α that can be suitable according to the actual needs of being convenient to reading, for example, α can be 60 °, easily push away to get D=n/2 according to above-mentioned formula this moment, be that the light of secondary light source 15 emissions is often at rule 13 top offset two 2cm, drill bit pierces ceiling 1cm, scale on rule 13 is the master scale of twice at this moment, namely the scale of the mark of length on rule 13 of actual two centimetres is one centimetre, so just played the effect that enlarges reading, what this moment, rule can be done is larger, be convenient in the ceiling lower end the rule reading.
the utility model in use, rotation is provided with the rotating shaft 3 on the guide pillar 10 of transparent cover body 4, make the upper surface of transparent cover 4 withstand the face of ceiling, then adjust the position of base 101, make the light of the first light source 5 on cover body 4 be radiated at the position that needs punching, the rotating shaft 3 of then rotating on the guide pillar 10 with drill bit makes guide pillar 10 rise, the drive electric drill rises, drill bit is during through the first source light and ceiling position of intersecting point, start drill bit, be rotated further rotating shaft, after drill bit changes enough degree of depth over to (this degree of depth can be controlled by the reading that reads on rule 13) rotating shaft stops operating, such drilling operation is completed.Owing to having adopted rack-and-pinion to drive the mechanism that electric drill rises, therefore guaranteed to get vertical hole on ceiling, can in boring procedure, not produce the skew of left and right.And determine that by the reading that reads on rule 13 electric drill pierces the degree of depth of smallpox plate hole, so drilling depth is controlled.
Referring to Fig. 5, described electric drill 7 comprises handle 73, at an end of described handle 73, battery 72 is housed, and has the motor 75 that drives drill bit in described electric drill 71, and described motor 75 comprises output shaft 750.
Also comprise body 78, be full of cooling water in described body 78, described body 78 forms the closed-loop path around motor 75 and in described electric drill 7, body 78 is provided with magnetic drives wheel 74 near described output shaft 750 inside, position, described output shaft 750 is fixedly installed permanent magnet 77 near a side of described magnetic drives wheel 74, when electric drill uses, motor output shaft 750 rotates the rotation that drives permanent magnet 77, drive the rotation of magnetic drives wheel 74 by the mode of magnetic transmission, thereby make the cooling water in body 78 to circulate.
Be provided with in described electric drill 7 for the storage tank 76 that stores cooling water, in described storage tank 76, more cooling water is set, described storage tank 76 and described body 78 are communicated with, so just can have enough cooling waters and absorb the heat that battery produces in the electric drill running, guarantee that the cooling water heat absorption is too much ineffective after the electric drill long-play.
Be provided with through hole 760 on described storage tank 76, electric drill 7 can be dismantled corresponding to the housing of through hole 760 positions, twist to be provided with on described through hole 760 and twist cap 761, in the long-time use procedure of electric drill, if need to increase or change cooling water in body 78, only need dismounting electric drill 7 corresponding to the housing of through hole 760 positions, turn on cap 761, add or pour out cooling water to get final product in through hole 760.
