Abstract

The utility model provides a drilling tool for a double hexagonal head bolt. The drilling tool comprises a hexagonal drilling jig body, wherein a workpiece hole for accommodating a middle hexagonal part of the double hexagonal head bolt is formed in the hexagonal drilling jig body; jig holes in two different directions are formed in the hexagonal drilling jig body; each jig hole is communicated with the workpiece hole; a positioning block can be arranged; and a positioning hole for accommodating a bolt rod part of the double hexagonal head bolt is formed in the positioning block. In addition, the drilling tool can be provided with a supporting seat used for fixing the hexagonal drilling jig body in which the double hexagonal head bolt is arranged and the positioning block, wherein the supporting seat at least comprises a base, a front seat wall and a rear seat wall; and a screw hole is formed in the rear seat wall and is matched with a locking bolt. The drilling tool is suitable for machining two anti-looseness holes in different directions of the middle hexagonal part of the double hexagonal head bolt, and is high in efficiency, easy to operate and high in safety, and the problems that the size machined by other machining method and the form and location tolerance are difficult to guarantee under the conventional condition are solved.

Description

The drilling tool of a kind of pair of hexagon-headed bolt
Technical field
The utility model relates to the drilling tool of a kind of pair of hexagon-headed bolt, and cooperation is holed to add to two anti-porosities of the different directions of six quadrate part positions in the middle of two hexagon-headed bolts and used man-hour.
Background technology
Two hexagon-headed bolts have received in Aeronautics and Astronautics, defence field widely and having used owing to possess good location and locking effect.Its relevant criterion all has special requirement to accurate positioning, anti-loosening property, the dimensional uniformity of two hexagon-headed bolts.This just requires position dimension, the form and position tolerance of the anti-porosity of two hexagon-headed bolts all must be controlled within certain scope.So the processing method of this anti-porosity is particularly important.The position at position because the locating hole after the processing mediates adopts Milling Process efficient too low, and product cost is high, has bigger mismachining tolerance, adopts conventional boring, and the uniformity of anti-porosity position size can't guarantee.Solve that above efficient is low, the problem of dimensional instability, the boring processing of two hexagon-headed bolts and measure and to possess following six characteristics: 1, simple and easy to operate.2, has versatility.3, accurate positioning.4, certainty of measurement is high.5, efficient is high.6, security is good.
Summary of the invention
The technical problem that the utility model will solve provides the drilling tool of a kind of pair of hexagon-headed bolt, solves pair bore size precision of the anti-porosity of hexagon-headed bolt middle parts different directions and measurement stability, conforming problem.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the drilling tool of a kind of pair of hexagon-headed bolt; Comprise six drill with ferrule die bodys; Have the workpiece hole of the six quadrate part positions, centre of putting into two hexagon-headed bolts on the six drill with ferrule die bodys, also have two nibs on the different directions on the six drill with ferrule die bodys, said each nib all connects with workpiece hole.
Further, for strengthening the stability of frock, this frock also is provided with a locating piece, has the locating hole at the tightening latch position of putting into two hexagon-headed bolts on the locating piece.
Further; For strengthening the stability of frock, this frock also is provided with one and is used for fixing pack into the six drill with ferrule die bodys of two hexagon-headed bolts and the supporting base of locating piece, and said supporting base has a base and forward and backward seat wall at least; Have a screw on the back seat wall, screw matees a clamping screw.
Further, said screw keeps concentric with the locating hole of workpiece hole that is placed on six drill with ferrule die bodys in the supporting base and locating piece.
Further, the axial line of said six drill with ferrule die body nibs intersects vertically with the axial line of workpiece hole respectively.Said nib is a through hole.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, these cover moulds of industrial equipment can be operated processing by general pincers worker personnel on common driller, and working (machining) efficiency is high, and security is good.Measuring easyly, use slide measure and micrometer to measure, is the major tuneup that the processing method of routine is carried out.

The specific embodiment
As shown in Figure 1, the utility model is processed two anti-porosities of the different directions of the six quadrate part positions, centre of two hexagon-headed bolts.Fig. 2 has provided the structure cross-sectional schematic of the six drill with ferrule die bodys of the utility model; Can find out the workpiece hole that has the six quadrate part positions, centre of putting into two hexagon-headed bolts on the six drill with ferrule die bodys; Also have two nibs on the different directions on the six drill with ferrule die bodys, said each nib all connects with workpiece hole.As shown in Figure 3, have the locating hole at the tightening latch position that is used for fixing two hexagon-headed bolts on the locating piece of the utility model.Present embodiment is that example describes with the embodiment with two nibs only.Two hexagon-headed bolts are packed in the six drill with ferrule die bodys, and the position at nib place is exactly the position that six quadrate part positions need get out anti-porosity in the middle of the double end hex bolts, and drill bit stretches in the nib, nib spacing down, can get out anti-porosity comparatively accurately.
For further avoiding six drill with ferrule die bodys and double end hex bolts generation offset in boring procedure; Strengthen the stability of this frock; This frock also be provided with one be used for fixing the tightening latch position of two hexagon-headed bolts locating piece and one be used for fixing the six drill with ferrule die bodys that two hexagon-headed bolts are housed and the supporting base of locating piece; Said supporting base has a base and forward and backward seat wall at least, has a screw on the back seat wall, and screw matees a clamping screw.Unclamp clamping screw, two hexagon-headed bolts are packed in six drill with ferrule die bodys and the fixed block successively, six drill with ferrule die bodys and locating piece that two hexagon-headed bolts will be housed then are placed on tightens clamping screw in the supporting base; The processing of can on common driller, holing; After having bored an anti-porosity, unclamp clamping screw, rotate six drill with ferrule die bodys to the another one die hole location; Tighten clamping screw and carry out the boring processing of second anti-porosity; Boring is unclamped clamping screw after finishing, and takes out the processing that two hexagon-headed bolts can be accomplished this workpiece.
Need to intersect vertically with the tightening latch axial line of two hexagon-headed bolts when loosening the hole, the axial line of then said six drill with ferrule die body nibs intersects vertically with the axial line of workpiece hole respectively.
For making the scrap after each boring can clear out of model drilling body smoothly, said nib is a through hole.
For the shank of bolt head of guaranteeing clamping screw can better push against workpiece to be processed, said screw should keep concentric with the workpiece hole that is placed on six drill with ferrule die bodys in the supporting base and the locating hole of locating piece.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
