Abstract
The utility model provides a bit with double cutting surfaces, which includes a drill pipe with cutting head, and a connecting joint combined with the drill, a cutting function part is also arranged above the cutting head, the distance between the cutting function part and the cutting head is corresponding to the depth of the drilling hole, the cutting radius of the cutting function part is more than that of the drilling hole. The utility model doesn't need a special thickness control equipment, which can do thickness control treatment for the peripheral hole when drilling, so the connection sections of the plate and the link profile are at the same base-level, the utility model can ensure the formation of the curtain walls and can easily raise the earthquake prevention performance of the curtain walls.
Description
The utility model relates to a kind of drill bit.
Fragile material curtain walls such as post-cut fixing stone need be holed to sheet material, and the crab-bolt parts are installed in the hole, are installed in articulating on the section bar of building surface then.Because sheet metal thickness has certain error range, therefore need to solve the flatness problem of curtain wall.At present, abroad adopting with the slab is benchmark, adopts the method for positioning sleeve evagination to solve to thin plate, but back sheet material is installed thus and is articulated the gap that existence does not wait between the section bar, can produce torsion and influences the shockproof properties of curtain wall.Another kind of solution is earlier sheet material to be controlled thick preliminary treatment, and then boring, makes sheet material be in same datum level with articulating being connected of section bar, has so not only guaranteed the flatness of curtain wall but also has been convenient to adopt technological means to overcome torsion.Though this solution can overcome above-mentioned defective, need add special equipment, the big operation of cost prolongs.
The purpose of this utility model is to provide a kind of two cutting faces drill bit of controlling thick processing and holing and finish simultaneously.
For achieving the above object, the utility model is by the following technical solutions: the utility model comprises drilling rod that has cutting head and the connector that cooperates with rig, it also is provided with the cutting functor above above-mentioned cutting head, distance between cutting functor and the cutting head with hole correspondingly deeply, the radius of clean-up of this cutting functor is greater than the radius of being holed.
The utility model also can adopt following further technical scheme simultaneously:
Be provided with the cutting pedestal between connector and drilling rod, described cutting functor is located at the cutting pedestal.Perhaps, the utility model is provided with the cutting pedestal that is connected with drilling rod, and described cutting functor is located at the cutting pedestal.Perhaps, the utility model is provided with the cutting pedestal that is connected with connector, and described cutting functor is located at the cutting pedestal.Perhaps, described cutting functor is located at connector.
Owing to adopt above technical scheme, the utility model need not the thick equipment of special-purpose control, in boring, to controlling thick processing around the hole, make sheet material be in same datum level, not only guaranteed the flatness of curtain wall but also can improve the shockproof properties of curtain wall easily with articulating being connected of section bar.
The utility model will be further described below in conjunction with drawings and Examples.

Embodiment 1
With reference to accompanying drawing 1,2.The utility model comprises drilling rod 2 that has cutting head 1 and the connector 3 that cooperates with rig, it also is provided with cutting functor 4 above above-mentioned cutting head, distance between cutting functor and the cutting head with hole correspondingly deeply, the radius of clean-up of this cutting functor is greater than the radius of being holed.
The setting of cutting functor can be adopted following structure: be provided with cutting pedestal 15 between connector and drilling rod, described cutting functor is located at the cutting pedestal.The cutting functor of present embodiment is a diamond dust, also can be other functors such as cutter certainly.
Drawing reference numeral 6 is the hole of being bored, the recess of the placed antidetonation pad that drawing reference numeral 7 forms after handling for 4 pairs of plate surfaces of cutting functor cut.
Embodiment 2
With reference to accompanying drawing 3.Present embodiment is that the another kind of the utility model cutting functor is provided with structure: it is provided with the cutting pedestal 25 that is connected with drilling rod, and described cutting functor is located at the cutting pedestal.The cutting pedestal can be sleeve, and the present embodiment sleeve is threaded with being connected to of drilling rod, also can be modes such as welding certainly.
Embodiment 3
With reference to accompanying drawing 4, present embodiment is that the another kind of the utility model cutting functor is provided with structure: it is provided with the cutting pedestal 35 that is connected with connector, and described cutting functor is located at the cutting pedestal.The cutting pedestal can be sleeve, present embodiment sleeve and connector be connected to welding, also can be mode such as be threaded certainly.
With reference to accompanying drawing 5, present embodiment is that the another kind of the utility model cutting functor is provided with structure: described cutting functor is located at connector.
Embodiment 5
With reference to accompanying drawing 6, it is identical with embodiment that present embodiment cutting functor is provided with structure, and its cutting pedestal 55 has the bigger annular solid of a diameter 58, and the cutting functor is located at annular solid.
