Abstract
The utility model provides a wall line box hole start bit structure, links together with a plurality of endocentric tube -shape cutter (2) with tube -shape cutter (2) endocentric straight -bar drill bit (1) to at many tube -shape cutter (2) tip welding graininess tool bit (3). Use straight -bar drill bit (1) centering, drilling processing is carried out simultaneously in a plurality of concentric tube -shape cutter (2), accomplishes the trompil processing in wall line box hole fast.
Description
Technical field
This utility model is related to a kind of wall line box hole opening bit structure.
Background technology
Existing wall line box hole perforate uses brill, pick instrument and wall is carried out dig the mode cut and carries out perforate,
Need repeatedly to be dug to cut the perforate that just can complete line box hole, low production efficiency, and higher to the skill set requirements of operator.
Through improving although occurring in that the drilling tool of straight-bar type drill bit group unification circle water drilling drill bit in prior art, but
Because it is difficult to be suitable for difference metope, the in the hole material after cutting is difficult to automatic classifying and throws away, and use occasion is restricted, some fields
Conjunction still needs to be cut mode and just can be completed perforate using auxiliary chisel.
Content of the invention
The defect of the low production efficiency existing for the perforate of current wall line box hole, this utility model provides a kind of new
Wall line box hole opening bit structure, this structure rotated using multiple concentric tubular cutters simultaneously, and numerous cutter heads are to wall
Carry out drilling processing, in the hole defective material is size-reduced to be thrown away automatically, once complete the perforate work in line box hole, thus improving production effect
Rate.
This utility model solves its technical problem and be the technical scheme is that a kind of wall line box hole opening bit knot
Structure, including the straight-bar drill bit being connected with electric drill, be is characterized in that: with the concentric multiple tubular cutters of straight-bar drill bit with straight-bar drill bit even
It is connected together, the end of each tubular cutter is welded with multiple cutter heads.
The wall line box hole opening bit of this kind of structure, carries out drilling to wall by multiple concentric tubular cutters simultaneously and adds
Work, simultaneously for increasing the accuracy of perforate, adds concentric drill bit in the middle of multiple concentric tubular cutters, is multiple concentric
Certralizing ability is provided during tubular tool sharpening and improves stability during tubular cutter drilling processing.
The quantity of tubular cutter can be selected according to the difference of body of wall material, and for normal concrete, general setting 3-4 is individual
Cutter, from the point of view of electric drill power and service efficiency and cutting effect, the quantity of tubular cutter is preferably 3.
In order to ensure the efficiency cut, preferable scheme is to be welded with many graininess knives in the end of each tubular cutter
Head, its particular number and distributing position determine according to power and the rotating speed of electric drill, are advisable with ensureing that electric drill can smoothly rotate.
The beneficial effects of the utility model are to be rotated using multiple concentric tubular cutters, numerous graininess cutter heads simultaneously
Wall is carried out with drilling processing, in the hole defective material is size-reduced to be thrown away automatically, the perforate work in wall line box hole can be rapidly completed,
And can ensure that higher position of opening accuracy and the stability of perforate work.
Brief description
Fig. 1 is the structural representation of wall line box hole of the present utility model opening bit.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
As shown in figure 1, wall line box hole of the present utility model opening bit structure, including straight-bar drill bit 1, with straight-bar drill bit
1 concentric for multiple tubular cutters 2, straight-bar drill bit 1 and multiple tubular cutter 2 link together so that straight-bar drill bit 1 and multiple
The combined drill that tubular cutter forms a whole, straight-bar drill bit 1 is longer than tubular cutter, with ensure into during brill by straight-bar drill bit 1
Play positioning action.Weld multiple graininess cutter heads 3 in the end of each tubular cutter 2, the material of cutter head 3 is according to difference simultaneously
Processed metope selected.
Claims (3)
1. a kind of wall line box hole opening bit structure, including the straight-bar drill bit (1) being connected with electric drill, be is characterized in that: same to straight-bar
The concentric multiple tubular cutters (2) of drill bit (1) are linked together with straight-bar drill bit (1), the end welding of each tubular cutter (2)
There are multiple cutter heads (3).
2. wall line box hole as claimed in claim 1 opening bit structure, is characterized in that: the quantity of described tubular cutter (2)
For 3.
3. wall line box hole as claimed in claim 1 or 2 opening bit structure, is characterized in that: described cutter head (3) is graininess
Cutter head.
