Outside be connected with mounting base.
Further, it is symmetrically arranged with the waist-shaped hole of perforative T font on the sleeve, is waist type close to sleeve inner
Screw tap set is fixed in the sleeve of tapping frame body by the smaller hole in hole, the waist-shaped hole that pin shaft passes through sleeve, and the both ends of pin shaft are equipped with
Rolling element, rolling element are located in the large hole of waist-shaped hole.
Further, pressure spring is housed between the sleeve and the end face of screw tap set free end, pressure spring is located at the blind hole of sleeve
It is interior.
Further, the rolling element is rolling bearing or idler wheel.
The present invention also provides a kind of method with lathe process internal screw thread, using the tapping tool of above-mentioned any one,
Drill bit is installed on tail stock, the mounting base of tapping tool is movably connected on lathe saddle, and workpiece is stuck in the chuck of lathe
On；
Drilling: first moving the middle carriage connecting with lathe saddle, so that the tapping tool being located on lathe saddle does not influence drill bit
Drilling pushes tail stock that drill bit is made to be located at the side at workpiece end to be processed, then carries out to knife, after knife, carries out
Drilling, after drilling, so that tail stock retreats to the initial end of lathe；
Tapping: moving middle carriage again, so that tapping tool is consistent with the boring direction to tapping, mobile big palette is driven
Lathe saddle complete tapping tool and workpiece to knife, after knife, carry out tapping, lathe saddle retreats to original after tapping
At beginning position.
The beneficial effects of the present invention are: having three: 1 using this lathe thread machining device effect, improving screw thread process
Efficiency, the time for replacing cutter only have original 1/3, and screw tap becomes flexible feed, easy to operate；2, mitigate worker's labour significantly
Intensity reduces the number of dragging tail stock；3, the abrasion of tailstock tool is reduced.

Specific embodiment
Below according to drawings and examples, the present invention is further described.
As shown in Figures 2 and 3, a kind of tapping tool for internal thread machining, including screw tap 3-1, screw tap cover 3-2 and attack
Guide frame body 3-3, screw tap 3-1 are fixed in the mounting hole of screw tap set 3-2 and use bolt fastening, and screw tap set 3-2 is sleeved on tapping
In the sleeve 3-31 of frame body 3-3；The waist-shaped hole 3-21 of perforative T font is symmetrically arranged on the sleeve 3-31, close to sleeve
It is the smaller hole of waist-shaped hole 3-21 inside 3-31, pin shaft 3-4 fixes screw tap set 3-2 across the waist-shaped hole 3-21 of sleeve 3-31
In the sleeve 3-31 of tapping frame body 3-3, the both ends of pin shaft 3-4 are equipped with rolling element 3-6, and rolling element 3-6 is located at waist-shaped hole 3-21
Large hole in；When tapping tool is in tapping operation, when feed, screw tap cover 3-2 with the rotation of workpiece and towards inside workpiece
Feeding, screw tap cover 3-2 and pin shaft 3-4 towards sleeve 3-31 movement outside (direction far from pressure spring 3-5)；When withdrawing, screw tap covers 3-2
With the rotation of workpiece towards inside workpiece feed reversing, it is (close towards sleeve 3-31 medial motion that screw tap covers 3-2 and pin shaft 3-4
The direction of pressure spring 3-5).The rolling element 3-6 is rolling bearing or idler wheel.Mounting base 3- is connected on the outside of sleeve 3-31
32, mounting base 3-32 are used for the fixation of tapping tool.
As the improvement of the present embodiment, pressure spring 3- is housed between the sleeve 3-31 and the end face of the screw tap set free end 3-2
5, pressure spring 3-5 are located in the blind hole of sleeve 3-31, the bottom of side and sleeve 3-31 blind hole of the pressure spring 3-5 far from screw tap set 3-2
Fixed, the purpose of setting pressure spring 3-5 is that tapping tool when to knife, has certain rebound between screw tap set 3-2 and pressure spring 3-5
Surplus avoids screw tap 3-1 from contacting firmly with workpiece, defective work piece or screw tap 3-1.
As shown in Figure 1 to Figure 3, a method of with lathe process internal screw thread, using the tapping tool of above-mentioned any one,
Drill bit 5 is installed on tail stock 6, the mounting base 3-32 of tapping tool is movably connected on lathe saddle 4, and workpiece 2 is stuck in vehicle
On the chuck of bed 1；
Drilling: first moving the middle carriage connecting with lathe saddle 4, so that the tapping tool being located on lathe saddle 4 does not influence to bore
First 5 drilling, pushes tail stock 6 that drill bit 5 is made to be located at the side at the end to be processed of workpiece 2, then carries out terminating knife on knife
Afterwards, it drills, after drilling, so that tail stock 6 retreats to the initial end of lathe 1；
Tapping: moving middle carriage again, so that tapping tool is consistent with the boring direction to tapping, mobile big palette is driven
Lathe saddle 4 completes tapping tool with workpiece 2 to knife, after knife, carries out tapping, lathe saddle 4 moves back after tapping
To original position.
Above-mentioned procedure of processing repeatedly realizes the batch machining of workpiece internal thread hole.
Tapping tool of the invention is combined with lathe and is used together, drilling with threading tool be separately mounted to tail stock and
On lathe saddle, the number for dragging tail stock is set to reduce 1/2, it is only necessary to rotate lathe saddle, simple and fast, maintenance side
Just.The labor intensity for mitigating worker significantly, improves processing efficiency, and the time for replacing cutter only has original 1/3.
