Abstract

The invention relates to the technical field of hardware tools, and particularly relates to a novel pilot drill. The novel pilot drill comprises a cutting part and a handle part, wherein the handle part adopts a regular hexagonal prism structure; positioning threads are formed between the cutting part and the handle part; a positioning nut is arranged on the positioning threads; and a cutting edge at the front end of the cutting part adopts a right angle. The novel pilot drill has the advantages that the structure is simple and reasonable, the regular hexagonal prism structure handle part can be easily fixed on a three-jaw chuck, the handle part is not easy to slip on jaws, the handle part can be in contact with end surfaces of the jaws by turning the positioning nut, axial displacement between the handle part and the jaws can not occur, the safety of the bill during machining is guaranteed, and the production efficiency is improved.

Description

A kind of novel pilot bit
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of novel pilot bit.
Background technology
Drill bit is hardware and cutting-tools common in machining, be generally used for the operation such as centering, boring, bore hole of workpiece, and the drill bit using in different technological processes also differs from one another.At present common drill bit generally comprises cutting portion that twisted shape puts the first edge on a knife or a pair of scissors and the clamping shank of cylindricality, after shank grips by fixture and rotate and process thereupon.Perforate adds and often there will be man-hour chucking power deficiency, cutting edge passivation, the workpiece material of fixture to have the situations such as hard spot, makes to get loose and skid between drill bit and fixture, causes scrapping of drill bit and workpiece, affects manufacturing schedule.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of simple in structure, accurate positioning, novel pilot bit easy to use are provided.
For achieving the above object, the present invention is by the following technical solutions:
A kind of novel pilot bit of the present invention, comprises cutting portion and shank, it is characterized in that: described shank is positive six prism structure settings, between cutting portion and shank, is provided with positioning threads, and positioning threads is provided with setscrew nut; The cutting edge of described cutting portion front end at right angles arranges.
Further, described setscrew nut is provided with preposition ring near the end face of shank one side.
Further, described cutting portion front end is the cold rolling fluted drill of high-speed steel.
Beneficial effect of the present invention is: the present invention is simple and reasonable, and the shank of positive six prism structures is easily fixing on scroll chuck, makes to be difficult for skidding between itself and claw; After clamping, turn setscrew nut makes itself and the end face conflict of claw, makes axial displacement can not occur between shank and claw, has guaranteed that drill bit, adding the security in man-hour, enhances productivity.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In figure:
1, cutting portion; 2, shank; 3, positioning threads; 4, setscrew nut;
5, preposition ring.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of novel pilot bit of the present invention, comprise cutting portion 1 and shank 2, described shank 2 is positive six prism structure settings, with respect to common round handle drill bit, the shank 2 of positive hexagon on scroll chuck fixedly time, the skidding that can effectively avoid clamping tightly not cause.
Between above-mentioned cutting portion 1 and shank 2, be provided with positioning threads 3, positioning threads 3 is provided with setscrew nut 4; Setscrew nut 4 is provided with preposition ring 5 near the end face of shank 2 one sides; After shank 2 is fixed on scroll chuck, positioning threads 3 is placed in the outside of claw, and rotation setscrew nut 4 makes it near claw end face, and then preposition ring 5 and claw end face are conflicted, and adds drill bit and three grab between chuck and can not produce the axial displacement of skidding in man-hour.
Above-mentioned cutting portion 1 front end is the cold rolling fluted drill of high-speed steel, the cutting edge of cutting portion 1 front end at right angles arranges, and the horizontal rib length between two cutting edges of cutting portion 1 is less than 1mm, and then drill bit can accurately be located when centering is got ready, be difficult for producing shake, avoid interrupting drill bit.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
