Design like this, during use, makes drill bit just to the relevant position of top board, opens drill bit laser centering device, and during bit, laser generator and the lasing area that sends thereof rotate simultaneously, there will be a bright spot, can indicate bore position exactly directly over drill bit.Then, operating personnel keep vertical rod motionless, bow, close one's eyes, pull pull bar, make elevating lever drive drill bit to rise along sliding sleeve, until complete top plate drilling.Gu in boring procedure, operating personnel need not come back viewing, so can not be confused eye.
If drilling machine exists fault of eccentricity, due to the visual persistence phenomenon of human eye, immediately below drill bit, there will be a ring of light, thus make people's Timeliness coverage fault of eccentricity.
As optimization, described lever has two, and the force side of two levers is cut with scissors respectively on a connecting rod, above-mentioned connecting rod and two levers, vertical rod and elevating levers form parallel-crank mechanism, described sliding sleeve has two, and spacer sleeve, on elevating lever, is equipped with linear bearing in it.Design like this, more firmly, action is more steady.
As optimization, described vertical rod stage casing is provided with telescopic tube, and this telescopic tube is made up of the inner and outer tubes be nested together, and inner tubal wall and outer tube wall have a charge off hole, and are furnished with latch.Design like this, as required, can utilize latch and pin-and-hole, adjustment telescopic tube length.
As optimization, described outer tube top is provided with a fastening nut, and outer tube top has multiple cannelure, and outer tube top tube wall is divided into multiple tile fragment clevis tooth by above-mentioned cannelure, and fastening nut can by tile fragment clevis tooth hoop on inner pipe.Design like this, after adjusting telescopic tube length, recycling fastening nut, is locked, and prevents from, because this portable top plate drilling expansion bracket is unstable, causing top to pull borehole throw.
As optimization, described vertical rod lower end is fixing on a substrate by a universal ball joint, and vertical rod stage casing is provided with transverse arm and pallet, pallet is provided with pointed cone, described transverse arm is outstanding a weight, bottom it weight point and the pointed cone on pallet just pair time, the axis vertical of described drill bit.Design like this, by weight, can correct drill bit perpendicularity.
Before the present invention is unexposed, people's hand-held drill, when facing upward head boring, is difficult to get out the fixing perfect inclined hole of angle.
As optimization, it also comprises the workbench of band universal caster wheel and fence, and described vertical rod is fixed on fence.Design like this, when needing to hole on superelevation top board, can be fixed on fence by vertical rod, then push work platform, so as to realizing the top plate drilling of diverse location.
The portable top plate drilling expansion bracket of the present invention has design science, easy to operate advantage, is widely used in the operation of various top plate drilling.
