Replace with the tool 14, and then carry out the processing of the workpiece A.

After the workpiece A is finished, the spindle 13 is displaced to the side of the tool change mechanism 2 as described above (as shown in Fig. 6), and the tool changer 2 switches the tool 14 on the spindle 13 back to the reclaimer 3, and then The first slide 17 is displaced along the X-axis toward the work platform 11, so that the take-up portion 32 aligns the finished workpiece A above the work platform 11, and the second clamp arm 324 is relatively close to obtain the workpiece A as described above, such as As shown in Fig. 7, the first carriage 17 is then displaced toward the tray 5 in the X-axis direction, and the workpiece A is returned to the original tray 5 as it is reversed. Position to complete the process of a workpiece A. Therefore, the processing of each workpiece A in the tray 5 can be completed one by one by repeating the above-described process.

The processing machine type to which the present invention is applied, except for the three-axis machining machine including the above three axial relative displacements, may be a four-axis or five-axis machining machine in different embodiments, and also has the aforementioned X-axis, Three axial relative displacements of the Y and Z axes, and further one or two axes of rotation. In addition, in the three-axis machining machine, except that the working platform 11 is fixed and the main shaft 13 is disposed on the third sliding seat 19, and the first sliding seat 17 and the second sliding seat 18 are in three axial directions (X-axis, The Y axis and the Z axis are displaced relative to the work platform 11, and both the main shaft 13 and the work platform 11 are displaceable, for example, the main shaft 13 is displaced only in the Z axis, and the work platform 11 is in the X axis and Y. The axial displacement, or the main shaft 13 is displaceable in the X-axis and the Z-axis, and the work platform 11 is displaced only in the Y-axis. In the two cases, the tray 5 having the plurality of workpieces A is manually placed directly on the working platform. On the other hand, the retractor 3 mounted on the main shaft 13 can be used to take the workpiece A by the displacement of the work platform.

From the above description, it is not difficult to find the advantage of the present invention in that the reclaimer 3 is provided, such as the tool 14 being replaced in the magazine 21 or the spindle 13, at which time the spindle 13 and the working platform 11 of the machine 1 are both There are at least three axial relative displacements, regardless of only the at least three axial displacements of the main shaft 13 relative to the work platform 11, and the spindle 13 is moved to the position of the tray 5 to take the workpiece A, or the spindle 13 and the working platform 11 are both displaced to generate the aforementioned at least three axial displacements, and the working platform 11 is moved to allow the spindle 13 to take the workpiece A to the tray 5, which can pass through the spindle of the machine 1. 13 and the displacement action of the working platform 11 during processing, so that the reclaimer 3 can take the workpiece A from the tray 5 to the working platform 11 and be fixed by the jig 12, and the processed workpiece A can be processed from the working platform 11. The fixture 12 is taken away, so that it can cooperate with the programming of the processing machine to achieve the function of mechanically picking and placing the workpiece, such as the mechanical arm, and simultaneously solve the problem that the conventional processing machine picks up the workpiece by manual or mechanical arm, and At a lower cost, Automated pick and place machinery to effect the workpiece.
