The specific embodiment
According to Fig. 3 the formation example of the friction welded machine that the present invention relates to is described.
Left side on pedestal 1 has L side main shaft 20 and is rotated the L side chuck 21 of drive controlling by this spindle drive motor.
For making L side main shaft consistent with axis, the R side that is relative to the configuration on right side main shaft 10, R side chuck 11 are rotated drive controlling by this spindle drive motor.
On Z-direction, move the instance of controlling by R side feed motor 12 and ball screw 13 for R side main shaft 10 in the present embodiment.
About at least one side of two main shafts being relative to the configuration have the feed motor that on Z-direction, is carried out Position Control and get final product.
R side feed motor 12 is a servomotor, in friction welded joint operation, can access upsetting pressure and upsetting force (extruding force).
The paper upside of Fig. 3 on the axis of L side main shaft 20 and R side main shaft 10 possesses first tool table 30 that has first turntable 31.
First tool table 30 have through ball screw 32a on Z-direction, move the feed motor 32 of control, from advancing to the feed motor 33 of Position Control and at the feed motor 34 of the enterprising line position control of Y direction in that X-direction is enterprising towards main shaft with the perpendicular direction of main shaft.
Equally, the downside at main shaft possesses second tool table 40 that has second turntable 41.
Second tool table 40 is controlled by the feed motor with ball screw 42a 42, feed motor 43,44 respectively in the position of Z-direction, X-direction, Y direction.
In addition, what show in the present embodiment is the two turntable patterns that are made up of two groups of turntables, also can be three turntable patterns or four turntable patterns.
In addition, tool table also can be to possess the tool table that is carried out B axle revolution control.
Below, be example according to Fig. 1 with the workpiece W2 of the little formation axial region of the big workpiece W1 of relative external diameter and Bi Qi profile, the process example of carrying out friction welded joint is described.
Shown in Fig. 1 (a), workpiece W2 clamping is fixed on the L side chuck 21, make workpiece W2 rotation time, by being installed in the processing of omitting lathe tool 36 composition surfaces such as execution of instrument such as grade on illustrated first turntable 31 etc.
On the other hand, workpiece W1 clamping is fixed on the R side main shaft 10, implements composition surface and other necessary processing with throw 47 grades by the tool spindle 46 that is installed on second turntable 41.
Shown in Fig. 1 (b), workpiece W2 is stopped the rotation so that it is fixed, when crimping is installed in the workpiece W1 of R side main shaft 10, it is rotated at a high speed.
The upset force of this moment is by omitting illustrated R side feed motor 12 controls, because frictional heat and fusion when softening, are stopped the rotation, by the extruding of R side feed motor 12 upsets, carries out crimping when the composition surface.
The upset force of this moment, upset extruding force are by SERVO CONTROL.
Like Fig. 1 (c) with (d), the workpiece that engages after accomplishing is given workpiece each other through L side main shaft 20 and R side main shaft 10, can carry out necessary processing continuously with turning cutting tool 48 grades by enough milling cutters 47.
Fig. 2 shows the process example of friction welded and machining of the material of long size.
Respectively workpiece W2, W1 clamping are fixed on L side main shaft 20 and the R side main shaft 10, tool using 36,48 etc. are implemented required processing such as composition surface, and that kind is carried out friction welded shown in Fig. 2 (b).
When becoming long material through engage W1 and W2, can present a theatrical performance as the last item on a programme 49 centrepin 49a when core is pressed workpiece centre through being installed in core on the turntable, on one side implement necessary processing with lathe tool 36 grades, Yi Bian remove burr d in the junction surface generation.
Moreover, shown in Fig. 2 (d), give R side main shaft 10 with workpiece, also can further implement necessary processing.
Be the fixing situation of chuck with respect to one-sided in the existing friction welded machine, in the present invention, about be relative to the configuration and be rotated the rotary chuck of control by spindle drive motor; And, through with tool table combination, thereby can carry out machinings and friction welded such as turning and cutting continuously; The positioning accuracy of workpiece is high; The product size precision improves, and can carry out the actions such as burr removal at junction surface continuously, and productivity ratio improves.
