Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, and a kind of portable top plate drilling expansion bracket is provided.
For solving the problems of the technologies described above, this portable top plate drilling expansion bracket comprises vertical rod and elevating lever, and wherein vertical rod one side is fixed with sliding sleeve, and described elevating lever is just arranged in sliding sleeve, in described vertical rod, go back hinged lever, the force side of this lever has long slot bore, and described elevating lever is provided with a pin, and this pin is through described long slot bore, the force side of lever is connected with pull bar, on described elevating lever, be fixed with rig, its drill bit makes progress, and is furnished with drill bit laser centering device.Wherein drill bit laser centering device is referring to drilling machine laser centering device described in CN200970692Y.
So design, during use, makes drill bit over against 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 directly over drill bit, can indicate exactly bore position.Then, operating personnel keep vertical rod motionless, bow, close one's eyes, and 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 needn't come back and watch, so can not be confused eye.
If drilling machine exists fault of eccentricity, due to the visual persistence phenomenon of human eye, under drill bit, there will be a ring of light, thereby make people find in time fault of eccentricity.
As optimization, described lever has two, and cut with scissors respectively on a connecting rod force side of two levers, 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.So design, more firmly, action is more steady.
As optimization, described vertical rod stage casing is provided with telescopic tube, and this telescopic tube is comprised of the inner and outer tubes that are nested together, and inner tubal wall and outer tube wall have a charge off hole, and are furnished with latch.So design, can utilize latch and pin-and-hole as required, adjusts telescopic tube length.
As optimization, described outer tube top is provided with a fastening nut, and outer tube top has a plurality of cannelures, and above-mentioned cannelure is divided into a plurality of tile fragment clevis teeth by outer tube top tube wall, and fastening nut can be by tile fragment clevis tooth hoop on inner pipe.So design, adjusts after telescopic tube length, and recycling fastening nut, is locked, and prevents from, because of this portable top plate drilling expansion bracket shakiness, causing top to pull borehole throw.
As optimization, described vertical rod lower end is fixed 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, the pointed cone on its bottom weight point and pallet over against time, the axis of described drill bit is vertical.So design, can, by weight, proofread and correct drill bit perpendicularity.
Before the present invention is unexposed, people's hand-held drill, while facing upward head boring, is difficult to get out the fixing perfect inclined hole of angle.
As optimization, it also comprises the workbench with universal caster wheel and fence, and described vertical rod is fixed on fence.So design, in the time of need to holing on superelevation top board, can be fixed on vertical rod on fence, and push work platform then, so as to realizing the top plate drilling of diverse location.
The portable top plate drilling expansion bracket of the present invention has advantages of design science, easy to operate, is widely used in various top plate drilling operations.
