Abstract

PURPOSE:To recover automatically chips by providing a chip recovering nozzle located in an optional position to a spindle in a ram to shift the nozzle opposedly to a working section after the completion of working. CONSTITUTION:After the completion of working, a slide nozzle is lowered by driving an air cylinder, the tip of a suction nozzle 11 is located below the end of a spindle 3 and a ram 2 is sifted in a horizontal plane. Thus, the tip of the suction nozzle 11 is opposed to the working section to recover chips, after the completion of recovering chips, the slide nozzle is lifted by the drive of the air cylinder so that the nozzle 5 is fixed to the stand-by position and shifted to the following working.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip collecting device in a machine tool, which is capable of automatically collecting chips.

[0002]

2. Description of the Related Art In deep hole drilling and tapping of a casting material, chips are powdery and remain in the machined portion. For this reason, the chips are designed to be removed before proceeding to the next processing. In particular, it is difficult for chips to get into the holes and take them out in the case of hole processing on a horizontal surface or hole processing that does not penetrate. Pre-processing, for example, if tapping is performed with cutting chips remaining in the hole during tap preparation, not only complete threading will not be possible,
It is also possible that it may lead to tap loss.

[0003]

In recent years, machine tools have been automated and operated in an unmanned manner. To remove chips during hole machining, insert a magnet rod or blow the chips off with air. I had no choice but to rely on the manual work of workers.

[0004]

The structure of the present invention for solving the above-mentioned problems is to provide a chip collecting nozzle on a ram supporting a spindle to which a tool is attached, and to arrange the chip at an arbitrary position with respect to the spindle. The nozzle is supported on the ram via a moving device for positioning and moving.

[0005]

In the processing, the nozzle is supported at a position where it does not interfere with the processing, and after the processing is completed, the moving device moves the nozzle with respect to the main shaft to face the processing portion, and the nozzle collects the chips.

1 is a front view of a machine tool equipped with a chip collecting apparatus according to an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a plan view thereof.

A ram 2 of a machine tool 1 is provided with a spindle 3 for supporting a tool, and the ram 2 is positioned and moved to an arbitrary position in a horizontal plane (X-axis, Y-axis direction) with respect to a table 4 and vertically. It is positioned and moved to any position in the direction (Z-axis direction). A nozzle 5 for collecting chips is provided on the ram 2, and the nozzle 5 includes a flexible hose 6 and a recovery pipe 7.
It is connected to the dust collector 8 via.

The supporting state of the nozzle 5 will be described with reference to FIGS. FIG. 4 shows the front surface of the nozzle support portion, and FIG. 5 shows its side surface.

The nozzle 5 is integrally constituted by a suction nozzle 11, an air nozzle 12, a nozzle body 13 and a slide nozzle 14, and the slide nozzle 14 is movable in the vertical direction (vertical direction) with respect to the ram 3. As the slide nozzle 14 moves up and down, the suction nozzle 11 and the air nozzle 12 move with respect to the main shaft 3. The slide nozzle 14 is positioned and driven by an air cylinder 15. In the figure, reference numeral 16 is a solenoid valve for air shot, 17
Is a stop stopper and 18 is a cover. The nozzle 5 has a standby position 700 mm above the end of the main shaft 3, and is moved 1000 mm downward from the standby position by driving the air cylinder 15.

The operation of the machine tool having the above-configured chip collecting device will be described.

The nozzle 5 is at the standby position 700 mm above the end of the main shaft 3, and is fixed at the standby position during machining (for example, drilling). After the processing is completed, the slide nozzle 14 is lowered by the driving of the air cylinder 15, and the suction nozzle
The tip of 1 is positioned 300 mm below the end of the spindle 3, and the ram 2 is moved in the horizontal plane. As a result, the tip of the suction nozzle 11 faces the processed portion, and the chips are collected. After the collection of chips is completed, the slide nozzle 14 is moved upward by driving the air cylinder 15, the nozzle 5 is fixed at the standby position, and the next processing is started.

The movement of the nozzle 5 is incorporated into a machining program in advance, and the chips are collected in a series of machining cycles. Therefore, by incorporating the operation of collecting chips in the machining program of the machine tool 1 in unmanned operation, the machining in the machine tool 1 including the collection of chips is automated.

[0013]

In the chip collecting apparatus of the present invention, since the chip collecting nozzle positioned at an arbitrary position with respect to the main shaft is provided on the ram, the nozzle is moved to the processing section after the processing is completed. By facing each other, chips can be collected automatically. As a result, by incorporating a chip collection operation into the machining program of the machine tool in unmanned operation, machining in the machine tool including chip collection is automated.
