The processing unit 54 has a processing sliding seat 541 and a The processing portion 542 and a control portion 543; further, the extending direction of the horizontal rail portion 521 and the horizontal screw portion 522 is defined as a second axial direction Y1, and the vertical rail portion 531 and the extending direction of the vertical screw portion 532 It is defined as a third axial direction Z1.

Thereby, when the pair of driving portions 13 drive the pair of screw portions 12 to rotate in the same direction, the pair of first linking block portions 30 are moved in the same direction on the pair of screw portions 12, thereby making the pair The two interlocking block portions 40 drive the processing platform unit 20 to move on the sliding rail portion 11; and when the pair of driving portions 13 respectively drive the pair of screw portions 12 to rotate in opposite directions, the pair of first linking blocks are caused The pair of screw portions 12 are respectively moved in opposite directions, and the pair of second linking block portions 40 are linked to rotate the linking rod 221 to drive the rotating working platform 22 to rotate; in the aspect of the upright base 50, The horizontal driving portion 523 and the vertical driving portion 533 drive the horizontal screw portion 522 And the rotation direction of the vertical screw portion 532 can control the movement of the second axial direction Y1 and the third axial direction Z1 of the machining unit 54, and the control portion 543 controls the rotation angle of the processing portion 541 so that the rotation angle is The processing portion 541 reaches the desired processing position.

That is, the present invention utilizes the movement of the second axial direction Y1 and the third axial direction Z1 of the machining unit 54 to cooperate with the first axial direction X1 of the processing platform unit 20 and the rotation angle of the processing portion 541, that is, The relative position and angle between the processing portion 542 and the object to be processed 70 on the rotary processing platform 22 can be adjusted to achieve a desired processing position.

As shown in FIGS. 4A and 4B, when the pair of driving portions 13 drive the pair of screw portions 12 to rotate in the same direction, the pair of first linking block portions 30 are made identical on the pair of screw portions 12. In the movement of the direction, one of the first linking block portions 30 is moved from a first position P11 to a third position P13, and the other first linking block portion 30 is moved from a second position P12 to a fourth position P14. The pair of second linking block portions 40 are driven to move the two ends of the linking rod 221 in the same direction, and the processing platform unit 20 is moved on the sliding rail portion 11 (moving from a first processing position P1 to a second processing) Position P2).

As shown in FIGS. 5A and 5B, it is assumed that the pair of driving portions 13 respectively drive the pair of screw portions 12 to rotate in opposite directions such that the pair of first linking block portions 30 respectively face opposite directions on the pair of screw portions 12. When moving and moving to a fifth position P15 and a sixth position P16 respectively, the pair of second linking block portions 40 will drive the two ends of the linkage rod 221 to move in different directions, thereby causing the deflection to be driven. The rotary work platform 22 rotates the first angle θ 1 (angle of about 20 degrees).

As shown in FIGS. 6A and 6B, when the pair of driving portions 13 respectively drive the pair of screw portions 12 to rotate in opposite directions, the pair of first linking block portions 30 are respectively opposite in the pair of screw portions 12. Moving, and moving from the fifth position P15 and the sixth position P16 to a first When the seventh position P17 and the eighth position P18, the pair of second linking block portions 40 continuously drive the two ends of the linkage rod 221 to move in different directions, thereby increasing the deflection angle and driving the rotating working platform 22 The second angle θ 2 is rotated (the angle is about 45 degrees).

As shown in Figures 7A through 7C, it is a simplified schematic diagram of the movement and rotation of the rotary working platform 22 of the present invention.

As shown in FIG. 7A, the pair of first linking block portions 30 are moved in the same direction and the same distance (both are moved by a first length L1) on the pair of screw portions 12, so that the pair of second linking blocks are moved. 40 drives the two ends of the linkage rod 221 to move in the same direction, thereby driving the processing platform unit 20 to move the first length L1 on the sliding rail portion 11 (the operation diagram of the seventh diagram corresponds to the fourth A and the fourth B Figure).

As shown in FIG. 7B, after the pair of first linking block portions 30 are moved in opposite directions on the pair of screw portions 12 (the distance from the pair of driving portions 13 is a second length L2 and a first The three lengths L3) cause the pair of second linking block portions 40 to move the two ends of the linkage rod 221 in different directions, thereby causing the rotation of the rotating working platform 22 to rotate the first angle θ 1 (angle About 20 degrees; the action of the seventh B corresponds to the fifth A and fifth B).

As shown in FIG. C, the pair of first linking block portions 30 are respectively moved in opposite directions after the pair of screw portions 12 (the distance from the pair of driving portions 13 is a fourth length L4 and a fifth, respectively). The length L5) causes the pair of second linking block portions 40 to move the two ends of the linkage rod 221 to move in different directions, thereby deflecting the rotating working platform 22 to rotate the second angle θ 2 (angle about 45 degrees; the action of the seventh C diagram corresponds to the sixth and sixth B drawings).

As can be seen from the above description, the present invention can control the movement and rotation of the processing platform unit 20 by using the rotation of the pair of screw portions 12, which is different from the general processing platform on the market. The design that needs to be driven separately in rotation can not only effectively reduce the overall volume, but also has higher accuracy and stability under the use of twin-screw.

In summary, the advantages and effects of the present invention can be summarized as follows:

[1] The operation is stable and the accuracy is high. The moving pedestal of the five-axis processing machine of the prior art needs to be separately driven in the movement and rotation of the placing portion 941 of the workpiece holder 940, and the design of the two driving devices is relatively easy in accuracy. In the case of an error, the present invention controls the movement and rotation of the processing platform unit 20 by the rotation of the pair of screw portions 12, and utilizes the precise characteristics of the screw drive and the synchronous rotation of the twin-screw to make the processing platform unit 20 move and rotate. The accuracy and stability are relatively high.

[2] Effectively reduce the overall volume. The moving pedestal of the five-axis processing machine of the prior art needs to be driven separately in the movement and rotation of the placing portion 941 of the workpiece holder 940, and the design of the two driving devices is likely to cause a larger overall volume. The present invention only needs to control the rotation direction of the pair of screw portions 12, thereby controlling the movement and rotation of the processing platform unit 20, and the structure volume can be significantly smaller than the design of the two driving devices, so that it is effective Reduce the overall size.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects, and the invention has been in accordance with the provisions of the patent law.
