Description
Technical field
Diameter, which is applied to, the present invention relates to one kind is less than M10 millimeters of screwed holes, and the hole has certain morpheme will with external screw thread
The frock of the swivel nut processing asked, it is more particularly to a kind of to ensure the small-bore with external screw thread steel swivel nut of internal and external threads morphemes requirement
Endoporus tapping frock and its method.
Background technology
Some product structures are fastenedly connected place and need to constantly be repeated to dismount using aluminum material, and product, because of aluminum
Material hardness is low, is iteratively repeated easy disassembling and causes the damage of screw thread, so as to substantially reduce the service life of product.In order to solve
Problem above, typically is equipped with steel swivel nut to solve at the place of being fastenedly connected of these products.When Product Assembly required precision is compared
Gao Shi（Such as：Screw and external screw thread concentricity are not more than 0.022 millimeter of Φ, and screw and external screw thread precision are 6 grades）, it is necessary to which special add
Work manufactures high-precision swivel nut.In order to meet the requirement of production in enormous quantities, this swivel nut is typically completed by Digit Control Machine Tool, number
Lathe process efficiency high is controlled, but can not disposably complete the processing of internal and external screw thread, it is necessary to machine twice, due to inside and outside spiral shell
The benchmark of the processing of line is inconsistent, is particularly the processing to the internal thread of the swivel nut of high-precision concentricity requirement it cannot be guaranteed that with one heart
The problem of requirement of degree, is especially prominent.
The content of the invention
The invention provides a kind of small-bore endoporus tapping frock and its method with external screw thread steel swivel nut, solve
Existing lathe is to the processing of the internal thread of the swivel nut of high-precision concentricity requirement it cannot be guaranteed that the technical problem of concentricity.
The present invention is to solve above technical problem by the following technical programs：
A kind of small-bore endoporus tapping frock with external screw thread steel swivel nut, including platen, in lathe work
Machine tool three-jaw chuck is provided with platform, support tube is provided with platen, the support tube periphery of support tube is connected to
In machine tool three-jaw chuck, cylindrical shape connected unit is fixedly installed on the top surface of support tube, in the lateral wall of cylindrical shape connected unit
On be provided with cylindrical shape connected unit external screw thread, be provided with connecting cylinder internal thread on the inner hole wall of connecting cylinder, connecting cylinder passes through even
An internal thread is connect together with the cylindrical shape connected unit external thread bolt connection set on the lateral wall of cylindrical shape connected unit, in cylindrical shape
Steel swivel nut inner hole thread tapping hole is provided with the hole of the connecting cylinder of the top face of connected unit, in the lateral wall of steel swivel nut
On be provided with swivel nut external screw thread, be screwed onto with externally threaded steel swivel nut in steel swivel nut inner hole thread tapping hole, in steel spiral shell
What is covered is arranged above tapping cutter.
The bottom surface of steel swivel nut is upper annular top surface of the apical grafting in cylindrical shape connected unit（9）On, in the outer of connecting cylinder
Connecting cylinder rotating handles is bolted with the wall of side.
A kind of small-bore endoporus tapping method with external screw thread steel swivel nut, comprises the following steps：
The first step, support tube of the processing with cylindrical shape connected unit, the cylindrical shape connection set in the center of top of support tube
Tapping external screw thread on the lateral wall of platform, sets connecting cylinder internal thread, on the lateral wall of connecting cylinder on the inner hole wall of connecting cylinder
Connecting cylinder rotating handles is set；
Second step, connecting cylinder is screwed in cylindrical shape connected unit, and passes through connecting cylinder rotating handles（Screwed；
In 3rd step, the endoporus top that steel swivel nut is passed through into swivel nut external thread bolt connection to connecting cylinder, and make steel swivel nut
Bottom surface apical grafting is on the upper annular top surface of cylindrical shape connected unit；
4th step, by tapping cutter extend into the endoporus of steel swivel nut carry out internal thread it is threaded, during screw thread is threaded
The iron pin of generation is drained into the cavity in support tube.
Connecting cylinder is modeled to the use environment of swivel nut to be processed by the present invention, spiral shell beyond machining internal thread is before changing
Custom thinking on the basis of line external diameter, because the hole internal thread for processing swivel nut is on the basis of the central axis of swivel nut, it is ensured that
The concentricitys of swivel nut internal and external threads, meets the processing request of the swivel nut of high-precision concentricity requirement.
