Description
Technical field
The utility model belongs to Tool Design technology, is related to a kind of screw tap.
Background technique
Screw tap is one of common tool in machining, is the tool for machining internal thread, can be divided into according to shape
Spiral tap and straight sword screw tap can be divided into set tap and machine tap according to use environment, and tapping is one relatively difficult
Manufacturing procedure is cut because screw tap is almost embedded in workpiece, very big to the machining load of its tooth, and and workpiece
Contact surface it is very big therefore higher to the intensity requirement of screw tap, and screw tap can encounter silk during machining internal thread
Cone is difficult to cut in work piece, if encounter hardness biggish material, incision difficulty is higher, and is easily damaged cutter.
In addition, the threaded hole position deviation traditionally processed has reached 0.8mm or more, perpendicularity deviation reached 0.5mm with
On, seriously affect the quality of clamping apparatus.
Utility model content
The utility model provides a kind of screw tap to solve Problems Existing, to realize accurate tapping, guarantees wire hole position essence
The purpose of degree.
What the utility model was achieved through the following technical solutions are as follows: a kind of screw tap, comprising: screw tap ontology,
The screw tap ontology includes: tapping portion and shank section, described to attack
Silk portion is equipped with the cutting edge of spiral, and the chip space of spiral is equipped between cutting edge, and the tapping portion connects knife handle
Portion, described shank section one end are equipped with positioning region, and the positioning region is two positioning plate criss-cross constructions.
The surface of the screw tap ontology is equipped with titanium nitride coating.The cutting edge is equipped with thread, the thread
Between screw pitch be 0,5-2mm.The number of chip space 3-4.
The utility model has the following beneficial effects: the utility model structure is simple, easy to process, operation is easy, this is practical new
Type is provided convenient for positioning and is added using the cutting edge of spiral and the chip space of spiral, easy to process, the positioning region equipped with right-angled intersection
Work precision, using geometric tolerances such as machining accuracy, position degree, the verticalities that can greatly improve threaded hole after the utility model,
Improve the processing quality of clamping apparatus.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model right view
Wherein: 1 is cutting edge, and 2 be chip space, and 3 be thread, and 4 be tapping portion, and 5 be shank section, and 6 be positioning region.
