The workpiece that need to be processed is fixed on panoramic table by work piece part, starts lathe, is moved by milling machine and drives milling cutter to work,
Complete work pieces process.
Rotary table device described in the utility model, the work piece part include screw rod, nut and pressing plate;It is described
The termination of screw rod is arranged in T-slot;The pressing plate and nut are socketed on screw rod successively.It is placed in by the termination of screw rod T-shaped
In groove, by rotating nuts, the workpiece that need to be processed is gripped with panoramic table, realizing the mesh for fixing workpiece by pressing plate
's.
Rotary table device described in the utility model, formed between the axis of the milling cutter and the upper surface of panoramic table
One angle, the angle formed are the angle of angle head, and the workpiece that this angle angle is less than available for machining angle closes angle.
Rotary table device described in the utility model, the angle are 30 °.
Rotary table device described in the utility model, the upper end of the angle head are provided with alignment pin;Prevent main shaft
Angle head is shaken during rotation, influences precision and product processing quality.

Embodiment
Below in conjunction with the accompanying drawings and rotary table device described in the utility model is described in detail embodiment.
A kind of rotary table device described in the utility model, including three-head milling machine 1;The three-head milling machine 1 is provided with
Main shaft and workbench;As shown in Figure 1, Figure 3, in addition to angle head 2 and panoramic table 4;One end of the angle head 2 is connected with main shaft
Connect, the other end is provided with milling cutter 3;The panoramic table 4 is fixedly installed on workbench;The angle head 2 is in bending;The milling
Knife 3 is vertically installed on the end face of angle head 2 that it is connected;Formed between the axis of the milling cutter 3 and the upper surface of panoramic table 4
One 30 ° of angles, the angle formed are the angle of angle head 2, and the workpiece 5 that this angle angle is less than available for machining angle closes
Angle.As shown in Fig. 2 equidistantly it is provided with some T-slots on the panoramic table 4;Work piece part is provided with the T-slot.
As shown in figure 4, the work piece part includes screw rod 7, nut 8 and pressing plate 9;The termination of the screw rod 7 is arranged in T-slot;
The pressing plate 9 and nut 8 are socketed on screw rod 7 successively.It is placed in by the termination of screw rod 7 in T-slot, will by rotating nuts 8
The workpiece 5 that need to be processed grips the purpose with panoramic table 4, realizing fixed workpiece 5 by pressing plate 9.The angle head 2 it is upper
End is provided with alignment pin 6;Prevent that angle head 2 is shaken when main shaft from rotating, and influences precision and product processing quality.
The workpiece 5 that need to be processed is fixed on panoramic table 4 by work piece part, lathe is started, band is moved by milling machine
Dynamic milling cutter 3 works, and completes workpiece 5 and processes.
In the present embodiment, the 4th 360 ° of a diameter of 500mm of axle panoramic table 4 is set on numerically controlled machine and in master
30 ° of angle heads 2 are set on axle(The bigger angle head 2 of angle is can be replaced into according to process requirements)Realize with three axle lathes to five axles
The part machining function of lathe, below 500mm and workpiece 5 can be closed workpiece 5 of the angle less than 30 ° and realize linkage motion cutting.By returning
T-shape slot screw rod 7, nut 8 and pressing plate 9 on turntable 4 is fixed by workpiece 5, then angle head 2 is arranged on machine tool chief axis
Fill at knife, and the alignment pin 6 of side is installed in place, prevent that angle head 2 is shaken when main shaft from rotating, and influences precision and product
Crudy.Numerical control program is input in machine tool panel afterwards, when lathe receives this operational order order machine operation by
As requested carries out 360 degree of rotations, while movement around is realized on the benchmark of former lathe, can under the cooperation of angle head 2
Realize that angle is processed and can moved up and down.
