The utility model discloses simple structure, convenient to use, centre gripping fast, clamping -force is big, and the centre gripping is stable, also can not produce during drilling and remove the dislocation to ensured the precision of angle steel drilling, can satisfy the demand of using on different specification angle steel for iron tower.
Description
Technical field
The utility model relates to angle steel clamp art, specifically a kind of accurate fixture for angle steel drill.
Background technology
Angle steel drill fixture is frock important in steel truss girder bridge, manufacture of steel structure, and conventional has two kinds of angle steel drill fixtures.One adds a slot-type device by a screw rod to combine, screw end head withstands drift angle in angle steel, a termination of slot-type device is connected with screw rod, and the outer drift angle of angle steel drill model is withstood in another termination, rotary screw, can clamping angle steel drill model and angle steel, but because bore surfaces is angle steel two aerofoil, this fixture also fails to clamp angle steel both wings face completely, during boring, easy mobile dislocation, causes bit damage; Another kind of angle steel drill fixture is two independently clips, special clamping angle steel drill model and angle steel, but is too far away from due to the drift angle of angle steel and fixture, easily causes angle steel drill model and workpiece generation relative displacement, affect the borehole accuracy of workpiece during boring.If these two kinds of fixtures use simultaneously, will greatly increase operation easier and the operating time of workmen again, angle steel drill efficiency is low.The shortcoming and defect of angle steel drill fixture is commonly used, in the urgent need to developing special angle steel boring grab in order to overcome prior art.And be all at present angle steel according to different size, make the fixture of different size, be subject to certain restrictions in using, inconvenient in-site installation uses.
Utility model content
The purpose of this utility model is the accurate fixture for angle steel drill providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of accurate fixture for angle steel drill, comprise external splint and inner splint, cavity is formed between described external splint and inner splint, inner splint and external splint are L-type, the vertical part of inner splint offers the first screwed hole, described first screwed hole internal thread is connected with the first compressor arm, the left end of described first compressor arm is connected with pressure strip by clutch shaft bearing, the right-hand member of the first compressor arm is provided with the first rotating disk, the transverse part of clip plate is provided with the second screwed hole, described second screwed hole internal thread is connected with the second compressor arm, the lower end of described second compressor arm is connected with the second pressure strip by the second bearing, the upper end of the second compressor arm is provided with the second rotating disk.
As further program of the utility model: the thickness of described external splint and inner splint is 2 ~ 4cm.
As the utility model further scheme: described first rotating disk and the second rotating disk are equipped with anti-slip veins.
Compared with prior art, the beneficial effects of the utility model are: this device can fast clamp, and only need turn compressor arm can clamp; Chucking power is large, and adopt compressor arm precession to tighten, active force is large, and clamping is stable; Also can not produce mobile dislocation during boring, thus ensure that the precision of angle steel drill.Clamping different-thickness, the clamping device of both sides is all work separately, is independent of each other, and can meet the demand used on different size angle steel tower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of accurate fixture for angle steel drill, comprise external splint 1 and inner splint 2, cavity 3 is formed between described external splint 1 and inner splint 2, inner splint 2 and external splint 1 are L-type, the thickness of external splint 1 and inner splint 2 is 2 ~ 4cm, the vertical part of inner splint 2 offers the first screwed hole 4, described first screwed hole 4 internal thread is connected with the first compressor arm 5, the left end of described first compressor arm 5 is connected with pressure strip 6 by clutch shaft bearing 7, the right-hand member of the first compressor arm 6 is provided with the first rotating disk 8, the transverse part of clip plate 2 is provided with the second screwed hole 9, described second screwed hole 9 internal thread is connected with the second compressor arm 10, the lower end of described second compressor arm 10 is connected with the second pressure strip 11 by the second bearing 12, the upper end of the second compressor arm 11 is provided with the second rotating disk 13, described first rotating disk 8 and the second rotating disk 13 are equipped with anti-slip veins.This device can fast clamp, and only need turn compressor arm can clamp; Chucking power is large, and adopt compressor arm precession to tighten, active force is large, and clamping is stable; Also can not produce mobile dislocation during boring, thus ensure that the precision of angle steel drill.Clamping different-thickness, the clamping device of both sides is all work separately, is independent of each other, and can meet the demand used on different size steel tower corner iron.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
