Disk spring is provided with upper support chip, the lower bracing frame, described disk spring one end is fixed in the lower bracing frame, another
End is connected with pushing block, and the pushing block is provided with to be provided with jacket casing, the jacket casing in lower support chip, the upper support frame and is provided with
Knife bar, described knife bar one end is connected with milling cutter through the upper support frame, and the knife bar other end is connected with electro spindle, the electricity
Main shaft one end is connected with axle sleeve, and the axle sleeve is arranged on the jacket casing, and some friction plates are provided with the jacket casing.
Preferably, the friction plate is 3.
Preferably, the friction plate equal circumference arrangement.
The invention has the advantages that：
1st, auxiliary support mechanism can effectively reduce the axial deformation and vibration of knife bar in this deep hole machining, and reduction is cut
The noise that vibrations are produced is cut, machining accuracy is improved, extends cutter life.
2nd, disk spring can also produce very big elastic load when decrement very little, therefore with support chip
The aggravation of abrasion, although the decrement of disk spring can reduce, but enough load still can be provided until a certain numerical value, this
The big minor matter of one numerical value can be by adjusting the size of disk spring, and quantity and decrement are controlled.So,
The service life of support chip is substantially prolongs, the cost of supporting mechanism is reduced.This mechanism is applied to certain model in general
Enclose the processing of the large-caliber pipe fittings of interior any internal diameter size.
3rd, this form is cut on top using cutter, is conducive to the discharge of chip and being smoothed out for normal process.Such as
Fruit cutter is placed on bottom and cut, and the chip produced in process is also deposited in workpiece bottom, so can serious shadow
The continuation cutting of cutter is rung, influence is produced on machining accuracy and machined surface quality.Therefore cutter is placed on the upper of workpiece inner wall
Cut in portion.
4th, using dismountable component rubbed, the replacing of part can be easy to, processing cost is reduced.

Embodiment
In order that objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further
Describe in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
As shown in figure 1, the embodiments of the invention provide a kind of tooling system of turn-milling cutting large-diameter pipe endoporus, including under
Support chip 1, upper support chip 9, pushing block 2, disk spring 3, upper support frame 8, lower bracing frame 4, jacket casing, milling cutter 5, knife bar 6 and friction
Piece, the upper support frame 8 be cube support frame, the lower bracing frame 4 be hollow tube-shape cylinder, the upper support frame 8 with
The lower bracing frame 4 is connected, and the upper end of upper support frame 8 is provided with support chip 9, the lower bracing frame 4 provided with dish-shaped bullet
Spring 3, described one end of disk spring 3 is fixed in the lower bracing frame 4, and the other end is connected with pushing block 2, and the pushing block 2 is provided with
It is provided with lower support chip 1, the upper support frame 8 in jacket casing, the jacket casing and knife bar 6 is installed, described one end of knife bar 6 passes through institute
State upper support frame 8 and be connected with milling cutter 5, the other end of knife bar 6 is connected with electro spindle 7, and described one end of electro spindle 7 is connected with axle
Set, the axle sleeve is arranged on the jacket casing, and some friction plates are provided with the jacket casing.
It is worth noting that, the friction plate is 3.
In addition, the friction plate equal circumference arrangement.
This specific implementation turnning and milling large-diameter pipe inner hole knife tool system is driven using electro spindle, and electro spindle rear portion is with passing through axle sleeve
It is connected with hollow boring bar, the tooling system that the front portion connection present invention is designed.
As shown in Fig. 2 the operation principle of this specific implementation is：Knife bar 6 is connected with electro spindle 11, and the other end of knife bar 6 is passed through
