Description
Technical field
Lathe tapping taper shank described in the utility model, relates to a kind of lathe aid, is specially minor diameter internal thread machining tapping tool.
Background technology
In the production process of reality, when using engine lathe cutted thread class part, general wide-aperture internal thread can use threading tool to carry out turning, and the very difficult threading tool of the internal thread of small-bore has come, but adopts tap wrench to carry out hand tapping.This traditional processing method machining internal thread inefficiency, the internal thread of tapping and the workpiece error of perpendicularity are very large, and in addition because the stressed size of manual operation is uneven, often there will be screw tap tipping, accuracy of thread is low, and the reach of processing is also difficult to control.
For problem existing in above-mentioned prior art, a kind of novel lathe tapping taper shank of research and design, can taper shank portion of the present utility model be inserted in the taper hole of tail stock, use engine lathe processing minor diameter internal thread, thus the problem existing for overcoming in prior art is very necessary.
Summary of the invention
In view of problem existing in above-mentioned prior art, the purpose of this utility model is a kind of novel lathe tapping taper shank of research and design.To exist in prior art in order to solve:
1, hand tapping inefficiency;
2, the internal thread of manual tapping and the workpiece error of perpendicularity are difficult to ensure;
3, hand tapping unbalance stress, the easy tipping of screw tap;
4, machining screw length difficulty controls;
5, minor diameter internal thread cannot by problems such as lathe process.
Technical solution of the present utility model is achieved in that
Lathe tapping taper shank described in the utility model, comprises cone bar, guide rod, drill chuck and screw tap; It is characterized in that described leader casing is contained on cone bar, guide rod is equipped with drill chuck, and screw tap is loaded on drill chuck; Cone bar is loaded in the taper hole of tail stock;
Described cone bar is processed with screwed hole;
One end of described guide rod has endoporus, and be sleeved on cone bar, the other end of guide rod endoporus and taper shank is matched in clearance, and fit clearance ensures between 0.10 ~ 0.20, the requirement of form and position tolerance during in order to ensure machining screw; The other end is processed as Mohs No. 2 chuck handles, and Mohs No. 2 chuck handles are equipped with drill chuck; Mohs No. 2 chuck handles, carry out connection with the female cone of drill chuck and coordinate; Drill chuck itself is equipped with acting clamping wrench, can be firm by screw tap clamping, and in clamping process, drill chuck automatically can play and allow the positioning action of centres at screw tap center and workpiece to be machined.
Guide rod described in the utility model is processed with gathering sill, and guide pad is loaded in gathering sill, and is loaded on cone bar by fastening bolt and screwed hole, and guide pad is free to slide in gathering sill.
The top of gathering sill described in the utility model is processed with graduation mark.
Taper shank portion of the present utility model is inserted in the taper hole of lathe tail, tail stock is moved to and wants machining screw position to suitable position, rotate tailstock handle, screw tap is pressed onto on processed position, control stick is lifted on startup lathe is backward, lathe spindle low speed is rotated forward, now guide pad moves axially in gathering sill, the changing value of scale can be observed at any time, thus know the length of now machining internal thread, when being machined to the reach of requirement, to pressing down control stick, lathe spindle reversion screw die is made to exit workpiece, when processing the internal thread of different size, just use different screw taps.
The utility model has the advantages that apparent, be mainly manifested in:
1, owing to employing the utility model, production efficiency is substantially increased;
2, owing to employing the utility model, the precision of the form and position tolerance after internal thread machining is improved;
3, owing to employing the utility model, screw thread uniform force in processing, tooth form quality is high;
4, owing to employing the utility model, effectively reach can be controlled;
5, the invention solves can not to the problem of small diameter workpiece machining internal thread on lathe.
The utility model has novel structure, it is easy, easy to use to process, improve operating efficiency, improve the advantages such as Product Precision, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
