Description

A kind of screw tap high in machining efficiency

Technical field

The invention belongs to machining technology field, and in particular to a kind of screw tap high in machining efficiency.

Background technology

Screw tap is one of instrument conventional in machining, is the instrument for machining internal thread, can be divided into according to shape Spiral tap and straight sword screw tap, set tap and machine tap can be divided into according to use environment, tapping is one relatively difficult Manufacturing procedure, cut because screw tap is almost embedded in workpiece, it is 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 is during machining internal thread, it is desirable to internally Hole is processed, if run into hardness larger material, difficulty of processing is higher, and is easily damaged cutter.

The content of the invention

The invention aims to solve shortcoming present in prior art, and a kind of silk high in machining efficiency proposed Cone.

To achieve the above object, present invention employs following technical scheme:

A kind of screw tap high in machining efficiency, including taper shank, the right-hand member of the taper shank is fixedly connected with fixed prism, described solid The right-hand member for determining prism is fixedly connected with circular cone, and the left end of the taper shank is provided with tapping-head, and the tapping-head left end is fixedly connected with Bistrique, the left end of the bistrique are fixedly connected with positioning head.

Preferably, the tapping-head includes tooth sword, and the tooth sword is provided with chip area at least provided with three rows between tooth sword, The cutting edge portion of the tooth sword is provided with labial teeth and backteeth.

Preferably, the surface of the fixed prism is provided with stopper slot.

Preferably, the surface of the bistrique is provided with frosted layer.

Preferably, be formed in one structure between the taper shank, tapping-head, fixed prism and bistrique.

The technique effect and advantage of the present invention:A kind of screw tap high in machining efficiency proposed by the present invention, with prior art phase Than can more easily process internal thread, and injury tolerance minimumization to caused by blade, extend screw tap uses the longevity Life, present invention design is total, suitable for production and popularization and application.

Brief description of the drawings

Fig. 1 is the structural representation of the present invention;

Fig. 2 is the left view of the present invention;

Fig. 3 is the A portions schematic enlarged-scale view of the present invention.

In figure:1 taper shank, 2 fix prisms, 3 circular cones, 4 tapping-heads, 5 chip areas, 6 tooth swords, 7 bistriques, 8 positioning heads, 9 labial teeths, 10 backteeth, 11 stopper slots, 12 frosted layers.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Herein Described specific embodiment only to explain the present invention, is not intended to limit the present invention.Based on the embodiment in the present invention, The every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, belongs to this hair The scope of bright protection.

The invention provides a kind of screw tap high in machining efficiency as Figure 1-3, including taper shank 1, the right side of the taper shank 1 End is fixedly connected with fixed prism 2, and the right-hand member of the fixed prism 2 is fixedly connected with circular cone 3, and the left end of the taper shank 1 is provided with Tapping-head 4, the left end of tapping-head 4 are fixedly connected with bistrique 7, and the left end of the bistrique 7 is fixedly connected with positioning head 8.

Further, the tapping-head 4 includes tooth sword 6, and the tooth sword 6 is at least provided with three rows, and the row of being provided between tooth sword 6 Consider groove 5 to be worth doing, the cutting edge portion of the tooth sword 6 is provided with labial teeth 9 and backteeth 10, is easy to tapping.

Further, the surface of the fixed prism 2 is provided with stopper slot 11, is easy to fix.

Further, the surface of the bistrique 7 is provided with frosted layer 12, increases frictional force.

Further, be formed in one structure between the taper shank 1, tapping-head 4, fixed prism 2 and bistrique 7, increase knot Structure stability.

Operation principle:When carrying out internal thread machining, fixed prism 2 is inserted on electric drill head, positioning head 8 is aligned to be processed The endoporus of part, start electric drill so that the high-speed friction between endoporus, the frosted layer 12 and endoporus of bistrique 7 of bistrique 7 so that interior The temperature of hole surface increases, so that its material softens to a certain extent, is easy to tapping-head 4 below to carry out tapping, tapping First 4 abrasion of tooth sword 6 reduces, and extends its service life, and reduce the difficulty of tapping.

Finally it should be noted that:The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic, Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's Within protection domain.
