Abstract

PURPOSE:To enable chips remaining on a complicated recessed or projected surface to be efficiently removed by tilting a workpiece by a tilting device after a prescribed working has been completed, and by blowing compressed air on the workpiece from a nozzle in the tilted condition. CONSTITUTION:After the cutting work of a workpiece 4 has been completed, the cylinder 5a if a tilting device 5 is driven to tilt the workpiece 4 installed on an auxiliary table 6. When it has been tilted up to a prescribed position, the tilting device 5 is stopped in that position, and a solenoid valve 10 in an air circuit is operated, so that compressed air is blown toward the surface of the workpiece 4 from an air nozzle 9. Then, the chips 11 attached on the workpiece 4 and the chips 11 in the neighborhood thereof are blow away, and they are guided by an auxiliary guide 7 in a prescribed falling direction so as to be collected in a chip collecting box 8. Thus, since the chops 11 can be forcibly removed by air, the chips 11 can be securely removed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for removing chips generated in a machine tool body, or a device for processing a workpiece.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional chip removing device.

In the figure, 11 (represents the main body of a machine tool such as a drilling machine).

(2) is the spindle head, (3] is a cutting tool such as a drill +41 is the workpiece to be machined, αυ is the workpiece +4
Automatic tool change equipment removes chips and shavings generated during machining.

α1 is a dust collector that collects chips αυ with air, Q
41 is a duct through which air and chips α1 pass.

The conventional chip removal device configured as described above can be operated as follows.

After completing the specified cutting process, return the cutting tool (31) to the automatic tool changer α, and then turn on the dust collector A3 with the machine tool body (!) with the sawn workpiece (4) still attached. The duct (141) sucks the chips αυ on the surface and surroundings of the workpiece (4) together with air, thereby removing the chips αυ on the surface and the surroundings of the workpiece (4).

[Problem to be solved by the invention]

Since the conventional chip removal device is configured as described above, it removes chips only by the dust collecting action of air, and completely removes chips remaining on the complex uneven surface of the workpiece (41). There were problems, such as the difficulty of removing it.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a chip removal device that can efficiently remove chips remaining on a complicated uneven surface.

[Means to solve the problem]

The chip removing device according to the present invention tilts the workpiece using a tilting device after completing a predetermined machining process.

When the workpiece is in an inclined state, the compressed fluid is sprayed onto the workpiece by a nozzle.

[For production]

In this invention, after machining is completed, the workpiece is tilted by a tilting device, and the chips on the workpiece on the table tilted by the tilting device are removed by compressed air or Remove by spraying machining fluid or cleaning oil.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is a block diagram of a chip removing device according to an embodiment 1ζ of the present invention, and FIG. 2 is a block diagram showing a tilting operation state of the chip removing device according to an embodiment of the present invention.

In the figure, +11 is the machine tool body such as a drilling machine.

(2 is the spindle head, (3) is a cutting tool such as a drill.

(4) is attached to the workpiece, and (5) is attached to the machine tool body 11.

This is a tilting device that tilts the workpiece +41 using a hydraulically or pneumatically driven cylinder (5a) as required. (6) is also mounted on the tilting device (5).

This is an auxiliary table on which the workpiece (4) is placed. That is.

The tilting device (5) of this embodiment pivots one end of the paces (5C) arranged in parallel to the auxiliary table (6) so as to serve as a support shaft (5b), and the other end of the paces (5C) is placed at the position of the other pace (5C). It is composed of a cylinder (5a) which is pivotally connected to the cylinder (5a), and the pace (5c) and the auxiliary table (6) are tilted by the extension of the piston rod of the cylinder (5a).

(7) is an auxiliary guide that restricts the movement of chips αυ placed around the auxiliary table (6); (81 is a chip collection box);

(9) is an air nozzle that blows compressed air.

αQ is a solenoid valve that controls the air supplied to the air nozzle (9), and U is a chip generated during machining of the workpiece (4).

The chip removing device according to the embodiment of the present invention configured as described above can be operated in the following manner.

After the cutting of the workpiece (4) is completed, the cylinder (5a) of the tilting device (5) is driven as shown in FIG.

The workpiece (4) placed on the auxiliary table (6) is tilted. When the workpiece (4) is tilted to a predetermined position.

The tilting device (5) stops at that position and maintains its tilted state. Then, operate the solenoid valve no of the air circuit,
Compressed air is blown from the air nozzle (9) toward the surface of the workpiece (4). The chips αυ attached to the workpiece (41) and the chips αυ in the vicinity are blown away and fall in the direction of gravity, and are guided in a predetermined falling direction by the auxiliary guide (7), and as a result, the chips are collected. Collected in box (8).

When the work of removing chips is completed, the tilting device (5) returns the auxiliary table (6) to the original machining position, positions it there, and moves the workpiece (4) to the next machining step.

In addition, when the air nozzle (9) is activated.

By swinging the head or the like, the direction can be changed to a plurality of positions on the surface of the workpiece (4) to spray air one-dimensionally, two-dimensionally, or three-dimensionally. In this case, it is necessary to drive the air nozzle (9) with another control system.

Further, the swarf collection box (8) may be configured to be removable and configured to discard the swarf when the amount of swarf reaches a predetermined amount.

Furthermore, the operation of the tilting device (5) is controlled by the cylinder (5a).
However, instead of this configuration, the tilting shaft is rotated by a rotary drive device such as a motor and gears.

A tilting motion can also be performed.

Yet again. In the above embodiment, a drilling machine is used as a machine tool.
Although this has been described as an example, this type of chip removal device can also be used for cutting in general, and for other machine tools 2, such as electrical discharge machining. Further, a combined machining machine 1ζ for cutting and electrical discharge machining can also be applied.

In addition, in the above embodiment, an air nozzle is used to spray compressed air, but the air nozzle may be used as a machining fluid nozzle to spray compressed machining fluid instead of air. .

Furthermore, in the milling machine, compressed clean oil may be sprayed from an oil nozzle.

〔Effect of the invention〕

As described above, the chip removing device of the present invention is provided.

A tilting device that tilts a workpiece mounted on a table of a machine tool on which the workpiece is mounted after machining is completed, and a compressed fluid that removes chips on the tilted workpiece. It consists of a spray nozzle, so after the processing process is completed.

Since the workpiece can be tilted using a tilting device and the chips can be forcibly removed by air, machining fluid, clean oil, or other fluid, there is an effect that the chips can be removed reliably. Furthermore, when operating a machine tool automatically, it has the effect of improving the reliability of automatic operation.
