Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a numerically controlled multi-axis automatic lathe having a function of sorting workpieces to be processed and automatically storing them.

<Conventional technology and its problems> In the past, multi-axis automatic lathes were not NC-controlled and had no program control, so simultaneous machining was impossible. Therefore, one type of work is processed, and there is no need to sort the work, and it is sufficient to store the work.

Recently, a multi-axis automatic lathe has been developed in which all axes (for example, 6 axes) are NC, and multiple workpieces can be arbitrarily machined by automatically switching NC programs.

For this reason, different kinds of works are carried out separately, but since they are stored in a single receiving box as in the conventional case, it is necessary to sort works of the same kind.

However, if the works of the same type are securely stored in the individual receiving boxes, the troublesome sorting work is eliminated.

The present invention aims to provide a numerically controlled multi-axis automatic lathe that automates this sorting work.

<Means for Solving the Problems> The present invention which achieves the above-mentioned object is provided with a work tray, a work tray which is communicated with the work tray and is automatically switched so as to sort each work by type, and A means for switching the position of the work tray based on a machining program of the conveyed work, and a receiving box for separately storing the work received by the work tray for each work of the same type by switching the work tray, It is characterized by having.

<Operation> When machining different types of workpieces, the tool slide is controlled by switching the program.
You can know the current work and the next work.
Therefore, the types of workpieces being machined are read by a program, and the work trays are switched so that the workpieces are stored in the same-type inbox due to this reading. It is separately stored in the inbox.

<Embodiment> An embodiment of the present invention will now be described with reference to FIGS. 1 to 3, the work 1 is received at the sixth position of the final machining step among all the axes of the multi-spindle automatic lathe (six axes in this embodiment as shown in FIG. 2). The work catcher is fixed to the main body by the support 2 so as to meet the sixth position. The work catcher is provided with a work receiver 3, which is operated by a cylinder 4 so as to move forward when receiving the work 1 and move backward after receiving the work 1.

 5 is a parting holder provided for the sixth position.

The work receiver 3 is connected to an automatic switching work tray 6 that determines the destination of the work 1 and a fixed work tray, and is connected to an individual receiving box 8 at the end.

The automatic switching work tray 6 is provided with a receiving box 8 by a cylinder 9.
Are selected and positioned. Then, the cylinder 4 of the work receiver 3 and the cylinder 9 of the automatic switching work tray 6 described above each have a solenoid valve 10 respectively.
The hydraulic control is performed to reverse or change the direction.

In this case, when receiving the workpiece 1 at the 6th position in the final machining step, the machining program of the M code is read from the NC device, and if the diameter of the workpiece 1 exceeds a certain value, the workpiece receiver 3 retreats and the diameter is exceeded. When the value becomes zero, it moves backward.

 For example, G × 2, F0.05 M80 × 0 M.81.

Here, x2 and x0 indicate diameters, and M80 and M81 indicate receding.

Further, the solenoid valve 10 may be switched depending on the type of workpiece being machined, for example, by the machining program of the M code.

MA M80, × 0 M81 MB G1 × 2, F0.05 M80 × 0 M81 In this case, MA indicates machining of the A work and MB indicates machining of the B work. Therefore, it is judged in the program during this processing, and the solenoid valve 10 is controlled to position the automatic switching work tray 6.

Here, the movement of the work 1 to the receiving box 8 will be described. As shown in FIG. 3, it is assumed that two types of works A and B are processed.

The workpiece receiver 3 advances to receive the workpiece 1 during the parting at the 6th axis position, and the workpiece receiver 3 waits for the falling portion.

At this time, the cylinder 9 of the automatic switching work tray 6 is
The path of the work catcher is arranged so that the work A is switched and the work A enters the inbox 8 of A.

When the work piece 1 is cut off by the cut-off holder 5, the work piece 1 slides down the work receiving tray 3 and the work trays 6 and 7 into the receiving box 8 of A. Then, the work receiver 3 retracts.

Even when the work B is used, the work receiver 3 and the automatic switching work tray 6 are controlled so that the work receiver 3 can enter the receiving box 8 of the work B.

<Effects of the Invention> As described above, according to the present invention, since a plurality of processed works are stored in the same type of receiving box by the automatic switching device, it is not necessary to classify the works. In addition, processing and collection of processed workpieces by type can be performed simply by commanding processing information (NC data for processing).
There is no need for a special command to collect processed workpieces by type.
