A lathe 6 with a loader device that runs between a work placing table 9 and a lathe 1 to attach / detach a work to / from the lathe 1, the cutting being attached to the loader device 6 when cleaning a work chucker. A chip removing brush 16 for removing chips is provided in the work transfer path.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lathe with a loader device for mounting a material work on a mounting table to a spindle chuck of a lathe, or receiving a finished product work held by the spindle chuck and delivering it to a measuring device outside the machine.

[0002]

[Prior art]

 The cycle of a conventional general loader device is as follows. First, the material work on the mounting table is received by one of the two chucks of the loader device and headed for the spindle chuck. After processing, the finished product is received by the empty chuck on the side that does not grip the material, and then the transferred material is delivered to the spindle chuck of the lathe. The received finished products will be sent out to the external measuring device etc. for feeding back the processing error. When a work is mounted on the spindle chuck with the above loader device, if chips are caught between the spindle chuck and the work, the attachment of each work will be varied due to poor adhesion, resulting in a decrease in machining accuracy. Therefore, in a conventional automated system, for example, air blow or coolant blow is performed every time the spindle chuck is opened and closed to clean the spindle chuck portion, and then the work is mounted on the spindle chuck.

[0003]

[Problems to be Solved by the Invention]

 Since the loader device is on standby outside the machine during cutting, there is no chance that chips will fall, but when cleaning the spindle chuck when delivering a workpiece, the chips scattered by an air blower etc. May adhere to and deposit on the chuck. The adhered cutting chips may drop when handing over the material or finished product and may be caught in the chuck part, or may be taken out of the machine and adhered to the outside of the machine, resulting in measurement error of the work size. was there.

The present invention has been made in view of this problem of the prior art. The purpose of the present invention is to remove the chips adhering to the loader device with the addition of a simple structure, thereby making it possible to produce scattered chips. This is intended to eliminate the harmful effects of this.

[0005]

[Means for Solving the Problems]

 A lathe with a loader device according to the present invention is provided with a brush for cleaning a work chuck portion of the loader device in the middle of a traveling path of the loader device for loading and unloading a work with respect to the lathe.

[0006]

[Action]

 The brush is located on the way of the traveling path of the loader device and sweeps away the chips adhering to the work chuck part of the loader device to prevent the accumulation of the chips on the part.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a machine tool using the gantry loader of the present invention, and FIG. 2 is a view showing a work chuck mode of the machine tool.

As shown in FIG. 1, a lathe 1 is a turret type in which two sets of a spindle 2 and a turret 3 are symmetrically provided, and are fixed to the ground by a bed 4. The spindle 2 and the turret 3 are cut off by an opening / closing door 5 which is opened and closed on the front surface of the machine for processing.

Further, rails 7 on which the loader device 6 is installed are installed on the left and right columns 8 above the machine tool 1, and a work mounting table 9 is provided below the laterally extending portions 7 a of the rail 7. There is. The work mounting table 9 has a table-like shape on which a large number of pallets are placed and rotated.

The loader device 6 has a moving base 11 installed on a traveling body 10 traveling along a rail 7, and a loader head 13 provided at a lower end of an elevating arm 12 supported by the moving base 11. As shown in FIG. 2, the loader head 13 is provided with a rotary chuck base 15 which is rotatable. Two loader chucks 14 are provided on the rotary chuck base 15 on the surface facing the spindle 2 and the lower surface, and the positions of both loader chucks 14 can be exchanged by turning the rotary chuck base 15.

Next, the operation of the above configuration will be described. The loader device 6 receives the unprocessed work (not shown) on the work mounting table 9 by the downward loader chuck 14, and after the elevating arm 12 is lifted, the traveling body 10 travels on the rail 7 to move the spindle. Stop at the position corresponding to 2. Then, when the loader head 13 descends again, the forward facing loader chuck 14 and the spindle 2 face each other, as shown in FIG. Then, the loader head 13 slightly moves to the left, and the empty loader chuck 14 facing forward receives the processed work W on the spindle 2. After that, the positions of both loader chucks 14 and 14 are exchanged by rotating the rotary chuck base 15, and the unprocessed work W is transferred to the spindle 2. When the work is received, it is conveyed again to the work mounting table (not shown) for the processed work by raising the elevating arm 12 and traveling the traveling body 10.

Although cutting chips are naturally generated at the time of machining the work, each time the loader chuck 14 is opened / closed for gripping the work, air cleaning is performed by the air generator A (not shown), and the loader chuck is The cutting powder is not attached to 14. However, at that time, chips adhere to the loader device 6, and the loader device 6 conveys the processed work W in that state. Then, when the processed work is placed on the work mounting table, the chips fall onto the processed work W due to vibrations or the like, and when measuring the dimensions in the subsequent process, an error of the cutting chips is generated. Will occur.

In order to prevent the chips from adhering to the above-mentioned processed work W, as shown in FIG. 1, in the middle of the transfer path of the loader device 6, the cutting is performed symmetrically above the front part of the lathe 1. A powder removing brush 16 is provided upright. Reference numeral 17 is a chip storage box for storing the removed chips. In this embodiment, the brush is used as the chip removing member, but the present invention is not limited to this example, and air cleaning with an air generator may be used.

Since the chip removing brush 16 is erected on the conveying path of the loader device 6, the brushing force of the chip removing brush 16 acts while the loader device 6 is running, so that the loader head 13 and The chips adhering to the periphery are removed.

Although the embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the above-mentioned embodiments and can be appropriately modified within the scope of the gist of the present invention.

[0016]

[Effect of device]

 As is clear from the above, the lathe with a loader device of the present invention removes adhering chips during the work transfer by the chip removing member each time the loader device is opened and closed for gripping the work. When measuring the dimensions in the process, an error of cutting chips is not generated.
