Description
Technical field
The utility model belongs to process tool technical field, relates to a kind of syndeton lengthening interrupted thread tap, particularly lengthens the syndeton in interrupted thread tap between taper shank and cone.
Background technology
Screw tap is the conventional tool of processing column shape and conical internal threads, be processing various in, the cutter of small size internal thread, its structure is simple, easy to use, both manually actuated, also can work on lathe, apply widely aborning.Existing screw tap is the reliability ensureing its quality, adopts Hardmetal materials to make, and because carbide alloy cost is high, if the screw tap of more corresponding overlength all adopts Hardmetal materials to make, then cost is high.In the process of screw thread, unnecessary scrap can be produced, if scrap can not be discharged in time, have impact on the processing effect of screw thread to a certain extent, the thread quality produced is defective, and the tooth distance of existing screw tap and width are all certain, adds that man-hour is stressed and cutting resistance is very large, easy wearing and tearing, service life is short.For this reason, there has been proposed taper shank and the split type setting of cone, then connected by demountable structure.But the design of existing syndeton is unreasonable, and the axiality connecting rear taper shank and cone is poor, rocks relative to taper shank adding man-hour cone, affect the machining accuracy of workpiece.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the syndeton of the lengthening interrupted thread tap of the high and good stability of a kind of reasonable in design, axiality.
The purpose of this utility model realizes by following technical proposal:
The syndeton of this lengthening interrupted thread tap, comprise the connecting rod being located at cone end and the connecting hole being located at taper shank end, described connecting rod and cone are coaxially arranged, described connecting hole and taper shank are coaxially arranged, it is characterized in that, the cross section of described connecting rod is rectangular, and the cross section of described connecting hole is in the rectangle matched with connecting rod cross section, and described taper shank is provided with for preventing connecting rod to come off the anti-disengagement unit in connecting hole.
In the syndeton of above-mentioned lengthening interrupted thread tap, described anti-disengagement unit comprises radial direction and is arranged in limiting through hole one on taper shank, is arranged in the limiting through hole two on connecting rod and is arranged in limiting through hole one and the caging bolt in limiting through hole two, the cross section of described limiting through hole one is square, the cross section of described limiting through hole two is square, and the size of described limiting through hole one is equal with the size of limiting through hole two.
In the syndeton of above-mentioned lengthening interrupted thread tap, the cross section of described caging bolt is square, and the size of described caging bolt is equal with the size of limiting through hole one.
In the syndeton of above-mentioned lengthening interrupted thread tap, the two ends of described limiting through hole one have limited impression respectively, one end of described caging bolt has the bar head being positioned at one of them limited impression, its other end has the threaded connector being positioned at another limited impression, described threaded connector is arranged with the nut being positioned at limited impression.
In the syndeton of above-mentioned lengthening interrupted thread tap, the outer surface of described bar head is equal with the outer surface radian of taper shank.The object of such setting makes the outer surface of bar head and the outer surface of taper shank in same radian face, ensures machining accuracy.
Compared with prior art, this syndeton has the following advantages:
Its reasonable in design, cone and taper shank can accurate fit, the good stability of posterior pyramids relative to taper shank of working good, axiality is high, adds to workpiece the machining accuracy that man-hour effectively ensures workpiece, and cone and taper shank easy to connect, accurate positioning, can connect fast.
