Abstract
The invention discloses a kind of gang tool, belong to machining technology field, the gang tool, including connection handle and drill bit, it is provided with bite between connection handle and drill bit, half cylinder blade that the bite is respectively equipped with contract block and contract groove by two junction surfaces, being fastened on outside the drill bit is formed；The connecting portion of the half cylinder blade and the drill bit is respectively equipped with axial crown and teeth groove；The through hole radially communicated is respectively equipped with the wall body of two half cylinder blades, the wall body of the drill bit is provided with the connecting hole corresponding to the through hole, and the trip bolt being fixed on two half cylinder blades on the drill bit is fitted with the through hole and the connecting hole.Once the present invention, which can solve existing gang tool partial destruction, needs integral replacing, the problem of causing waste and the high production cost of material.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of gang tool for work pieces process.
Background technology
Gang tool be machining in commonly use instrument, a kind of gang tool for lathe, include connection handle with
Drill bit, is provided with bite between connection handle and drill bit, be inserted into connection handle in the centre bore of machine tool mounting seat during use
Tighten, start lathe, machine tool high speed rotation carries out Drilling operation to workpiece；In process because machine tool running speed is very high and
The bit head or bite for easily making gang tool are worn, and existing gang tool, due to its connection handle, drill bit and bite
Integrally make, when drill bit or bite need integral replacing once damage, waste and the production cost for causing material are high
The problem of.
The content of the invention
The present invention provides a kind of gang tool, is needed integrally more once the cutter can solve existing gang tool partial destruction
Change, the problem of causing waste and the high production cost of material.
In order to solve the above problems, the technical solution adopted in the present invention is：This gang tool, including connection handle and brill
Head, is provided with bite between connection handle and drill bit, the bite is respectively equipped with contract block and contract groove, fastening by two junction surfaces
The half cylinder blade outside the drill bit is formed；The connecting portion of the half cylinder blade and the drill bit is respectively equipped with axial tooth
Point and teeth groove.
In above-mentioned technical proposal, more specifically technical scheme can also be：Divide on the wall body of two half cylinder blades
The through hole that She You do not communicate radially, the wall body of the drill bit are provided with the connecting hole corresponding to the through hole, the through hole and institute
State the trip bolt for being fitted with and being fixed on two half cylinder blades on the drill bit in connecting hole.
Further：The cross-sectional diameter of the drill bit is less than the cross-sectional diameter of the connection handle, the connection handle
Cross-sectional diameter is less than the cross-sectional diameter of the bite.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, half cylinder blade structure contract block and contract groove being respectively equipped with by two junction surfaces due to bite, being fastened on outside drill bit
Into；The connecting portion of half cylinder blade and drill bit is respectively equipped with axial crown and teeth groove, not only when drill bit or bite damage
Easily split, can respectively carry out changing and avoid the waste of material, and contract block and contract groove be firmly combined with it is reliable, meanwhile, add
Man-hour either turns clockwise or rotate counterclockwise, and axial crown and teeth groove can play and prevent bite in external force
The lower effect that relative motion is produced with drill bit of effect, combines both closer, ensure that both synchronous, reliable rotations；
2nd, due to being respectively equipped with the through hole radially communicated on the wall body of two and half cylinder blades, the wall body of drill bit, which is provided with, to be corresponded to
The trip bolt being fixed on two and half cylinder blades on drill bit is fitted with the connecting hole of through hole, through hole and connecting hole, enters one
Step improves the overall conjugation of two and half cylinders and drill bit, more ensure that their overall reliable rotations.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the sectional view at Fig. 1 A-A.
Embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Gang tool shown in Fig. 1, Fig. 2, including connection handle 1 and drill bit 3, bite 2 is provided between connection handle 1 and drill bit 3, bored
First 3 include drill bit connection handle and cutter head, and bite 2 is by two the first half cylinder blades 21 being fastened on drill bit connection handle outer wall
It is combined into the second half cylinder blades 22, the joint portion of the first half cylinder blades 21 and the second half cylinder blades 22 is respectively equipped with
Contract block 23 and contract groove；The first half cylinder blades 21 and the connecting portion of the second half cylinder blades 22 and drill bit 3 are respectively equipped with axial
Crown 31 and teeth groove；Be respectively equipped with the wall body of the first half cylinder blades 21 and the second half cylinder blades 22 radially communicate it is logical
Hole, the wall body of drill bit 3 are provided with the connecting hole corresponding to through hole, are fitted with the first half cylinder blades 21 in through hole and connecting hole
The trip bolt 4 being fixed on the second half cylinder blades 22 on drill bit；The cross-sectional diameter of drill bit 3 is less than the transversal of connection handle 1
Face diameter, the cross-sectional diameter of connection handle 1 are less than the cross-sectional diameter of bite 2.
The present invention is not only easily split when drill bit or bite damage, and can carry out changing the wave for avoiding material respectively
Take, and contract block and contract groove are firmly combined with reliable, and either turn clockwise when processing or rotate counterclockwise, axially
Crown and teeth groove can play a part of prevent bite in the presence of external force with drill bit produce relative motion, make both tie
That closes is closer, ensure that both synchronous, reliable rotations, meanwhile, it is fitted with through hole and connecting hole and is fixed on bite
Trip bolt on drill bit, the overall conjugation of two and half cylinders and drill bit is also further increased, more ensure that they are whole
Body reliably rotates.
