Abstract
The utility model relates to a guiding screw tap with an inlaid head, which belongs to a tapping tool and comprises a screw tap body and a cutting portion disposed on the screw tap body. The technical scheme includes that a replaceable cylindrical guiding column is inlaid at the front end of the screw tap body, and the axle center of the guiding column and axle centers of the screw tap body and the cutting portion are on the same straight line. The guiding screw tap has the advantages that the outer diameter and the tolerance of the guiding column can be fittingly manufactured according to the size of an actual threaded bottom hole of a machined part, and machining precision of the threaded hole is guaranteed, the screw tap body can be modified on the basis of a common standard screw tap, the guiding screw tap is reasonable in design, simple in structure, easy in machining, accurate in positioning and convenient in use, work efficiency is effectively improved, the error probability is decreased, cost is saved, and the like.
Description
Technical field
The utility model relates to the tapping instrument, and particularly a kind of tapping is with an edge guide tap, is applicable to the internal thread cut of aluminium suspension member etc.
Background technology
In industries such as machining, machine-building; The connecting hole of a lot of workpiece all needs tapping; Owing to the profile of workpiece, the position difference or the hole in hole are not reasons such as closed figure, still needing lathe or staff to adopt hand-operated tools under a lot of situation--screw tap is accomplished tapping work.
Yet utilizing hand-operated tools--when screw tap is processed internal thread; Usually have following problem: workpiece is in when footpath at the bottom of the machining screw; Screwed hole itself has grade of tolerance requirement, and also there is deviation in the processing of thread Pilot hole, for example: have very large deviation in the aluminium section bar thread Pilot hole process.Present screw tap mainly is made up of taper shank part and cutting tip; The guider that does not match with the workpiece core diameter of thread; The staff needs first mating holes position just passable when carrying out tapping to workpiece, and in the process of tapping; The axle center of screw tap be need firmly hold, gimlet and hole decentraction prevented.In case depart from the hole heart, will influence crudy, cause workpiece can not satisfy drawing requirement, make workpiece become defect ware, cause a large amount of wastes.And in working angles, the eccentric unstability of the cutting tip of screw tap also can make the cutting edge rapid wear, the service life of having reduced screw tap.
To sum up, existing screw tap is indefinite under certain environment to satisfy processing request, does not reach good processing effect, is badly in need of improving.
The utility model content
The purpose of the utility model is for a kind of simple in structure, accurate positioning, an edge guide tap easy to use are provided; Fundamentally solve existing screw tap in tapping process because the crudy that perpendicularity is badly confirmed, spiral shell and hole decentraction cause is poor, defect ware increases, the cutting edge rapid wear; Problems such as screw tap reduction in service life have the advantage of guiding tapping.
The technical scheme of the utility model is: this edge guide tap; Comprise the screw tap body and be arranged on the cutting tip on the screw tap body; Its technical essential is: said screw tap body front end studs with removable cylindrical lead; The lead material can confirm that the axle center of the axle center of said lead and said screw tap body, cutting tip is on same straight line according to the part to be processed material.
Said lead diameter adopts tolerance clearance to cooperate with the workpiece core diameter of thread.
Said screw tap body can adopt the transformation of the way of common standard screw tap.
Said lead front end is provided with circular chamfering.
Advantage of the utility model and positive technique effect are: the screw tap body of the utility model and the lead of its front end insert are split-type structural; Lead outside dimension and tolerance can be joined work according to workpiece actual thread bottom outlet size, have guaranteed the machining accuracy of screwed hole.The screw tap body can adopt the transformation of the way of common standard screw tap simultaneously, has utilized original resource.During use, make screw tap body and accurate work piece positioning through lead, rotate the screw tap body afterwards, then cutting tip can be to the workpiece tapping.
That this structure has is reasonable in design, simple in structure, be easy to processing, accurate positioning, characteristics such as easy to use, not only effectively raises operating efficiency, and has reduced fault rate, provides cost savings.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the concrete structure sketch map of the utility model.
Sequence number explanation among the figure: l screw tap body, 2 cutting tips, 3 leads.
The specific embodiment
According to Fig. 1 the utility model is described in detail.The described edge of a utility model guide tap can be made again, also can on the basis of existing screw tap, improve forming.
Its structure mainly by screw tap body l, be arranged on cutting tip (cutting edge) 2 on the screw tap body 1 etc. and form, screw tap body 1 front end studs with lead 3, lead 3 is fastenedly connected with the screw tap body, its end is provided with circular chamfering, prevents to damage workpiece.The diameter of lead 3 adopts tolerance clearance to cooperate with the workpiece core diameter of thread.Screw tap body 1 can adopt the transformation of the way of common standard screw tap.
In order to guarantee the concentric of spiral shell and hole, guarantee crudy, the axle center of the axle center of lead 3 and screw tap body 1, cutting tip 2 is on same straight line.During use, with attacking spiral shell in the lead 3 insertion workpiece hole.Can guarantee vertical cut, it is impaired to guarantee that cutting edge is difficult for.
The processing of the utility model, make all very simple and conveniently, but its guide effect has guaranteed that processing effect is remarkable.
Claims (4)
1. inlay a guide tap for one kind; Comprise the screw tap body and be arranged on the cutting tip on the screw tap body; It is characterized in that: said screw tap body front end studs with removable cylindrical lead, and the axle center of the axle center of said lead and said screw tap body, cutting tip is on same straight line.
2. an edge guide tap according to claim 1 is characterized in that: said lead diameter adopts tolerance clearance to cooperate with the workpiece core diameter of thread.
3. an edge guide tap according to claim 1 is characterized in that: said screw tap body can adopt the transformation of the way of common standard screw tap.
