Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip removing device for a turning machine that removes chips entangled in a turning tool bit.

[0002]

[Prior Art]

 Conventionally, chips are generated when cutting a workpiece using a turning machine, and especially when boring or drilling, the chips are entangled with the turning tool bite. Further, compressed air is used to remove the entangled chips. That is, as shown in FIG. 3, the turning machine 31 has a turning tool 32 having a rotary shaft 32 and a blade 33 provided at the tip of the rotary shaft 32, and a turning tool having a drive mechanism for rotating the turning tool 34. And a holder 35. Then, after boring or boring one workpiece, when the workpiece is moved toward the tip of the cutting tool 34, it is disposed in the vicinity of the cutting tool holder 35 in advance, and compression (not shown) is performed. The compressed air A is jetted from the nozzle 36 connected to the air supply source. Along with this, the sprayed compressed air A scatters the chips D entwined so as to wind around the tip side of the cutting tool 34, that is, near the blade 33.

[0003]

[Problems to be solved by the device]

 However, in the conventional method using compressed air as described above, the nozzle 36 for injecting the compressed air A is separated from the cutting tool 34 so as not to interfere with the workpiece fitted on the tip side of the cutting tool 34 during processing. In addition, the injection angle of the compressed air A to the bite 34 is large. Further, the cutting tool 34 can always blow the compressed air A from only one direction. For this reason, even if the compressed air A is blown to the cutting tool 34, the cutting dust D entwined around the rotary shaft 32 of the cutting tool 34 may not be completely removed (scattered). As a result, when the work pieces are continuously processed, there are some work pieces that are cut by the cutting tool 34 in which the chips D have not been completely removed, which is a factor that causes variations in the machining accuracy between solids. It was

The present invention has been made in view of such conventional problems, and reliably removes the cutting chips entangled in the bytes of the turning machine to improve the machining accuracy of the turning machine when performing continuous machining. An object of the present invention is to provide a chip removing device for a turning machine that maintains a constant value.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a drive unit provided with a turning machine and an outer periphery of a turning tool of the turning machine are externally fitted and reciprocate in the axial direction of the turning tool. As described above, the removing section supported by the driving section is provided, and the removing section is provided with an injection hole for injecting compressed air to the tip side of the cutting tool in the vicinity of the cutting tool. Further, it is preferable that a plurality of the injection holes are provided in the removing portion so as to surround the cutting tool.

[0006]

[Action]

 In the above configuration, when the cutting tool is entangled in the turning tool, when the removing part that is fitted on the outer circumference in the rotation direction of the turning tool is moved toward the tip of the cutting tool, the cutting tool is entangled around the cutting tool. The relatively large chips are moved toward the tip of the cutting tool together with the removing section. On the other hand, the removal section is provided with an injection hole for injecting compressed air on the tip side of the cutting tool in the vicinity of the cutting tool. Therefore, when the removal section is moved, the injection hole is always close to the byte. Compressed air is blown. Further, at this time, when a plurality of injection holes are provided so as to surround the periphery of the bite, the bite is blown with compressed air over the entire circumference.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIGS. 1 and 2, the chip removing device 1 for a turning machine according to the present invention has a drive unit 2 that is provided with a bite holder 35 of a turning machine 31 shown in the conventional example. A piston 3 which is parallel to the rotary shaft 32 of the bite 34 extending from the bite holder 35 is projectingly provided in the drive unit 2, and the piston 3 is provided inside the drive unit 2. A drive mechanism (not shown) for expanding and contracting in the direction is provided. A flange 4 is provided at the tip of the piston 3, and the flange 4 is provided with a removing portion 5 made of a thick-walled plate member that is fitted onto the outer periphery of the rotating shaft 32 in the rotation direction. It is installed by 6. The removing portion 5 is formed by a rectangular plate-like member, and one end side in the lengthwise direction is supported by the flange 4 while both ends on the other end side in the lengthwise direction are notched. And a U-shaped notch 7 into which the rotary shaft 32 is fitted is formed in the middle of the other end side.

Further, the removing portion 5 has a removing surface 8 on the tip end side of the cutting tool 34 that forms a substantially right angle with the axial center of the rotating shaft 32, and the removing surface 8 is close to the rotating shaft 32. Are provided so as to surround the rotary shaft 32. On the other hand, a compressed air supply path 10 communicating with the plurality of injection holes 9 ... Is provided inside the removal section 5, and the compressed air supply path 10 is in contact with the removal surface 8. A pipe 12 is connected to a supply source of compressed air (not shown).

In the above-mentioned configuration, after the cutting machine 31 performs boring or boring on one workpiece, the workpiece fitted on the cutting tool 34 is moved toward the tip of the cutting tool 34. Then, the piston 3 provided in the drive unit 2 is extended and operated by a drive mechanism (not shown), and the removing unit 5 fitted on the cutting tool 34 is moved to the tip side of the cutting tool 34. At the same time, compressed air is supplied from a compressed air supply source (not shown) through the pipe 12 to the moving removing section, and the supplied compressed air A is ejected from the ejection holes 9 of the removing surface 8. It Therefore, the chips D entwined around the rotary shaft 32 of the cutting tool 34 are moved toward the tip of the cutting tool 34 along with the movement of the removing unit 5 and are removed from the tip of the cutting tool 34. .. At this time, the compressed air A is blown toward the bit 34 toward the tip side of the cutting tool 34 from the injection holes 9 ... Not performed, for example, chips snarled by the blade 33 and relatively small chips are scattered by the compressed air A.

Therefore, the chips D entangled in the cutting tool 34 can be surely removed after boring or boring the workpiece, and even when a plurality of workpieces are continuously processed, Since there is no work piece to be processed by the cutting tool 34 whose chips have not been completely removed, it is possible to maintain a constant processing accuracy between solids.

Further, since a plurality of the injection holes 9 ... Are provided so as to surround the cutting tool 34, the compressed air A is blown onto the entire circumference of the cutting tool 34 when the removing unit 5 moves. Therefore, the chips can be more reliably scattered as compared with the case where the compressed air is blown from only one direction.

[Effect of the device]

 INDUSTRIAL APPLICABILITY As described above, according to the present invention, the drive unit provided with the turning machine and the drive unit so as to be fitted onto the outer periphery of the turning tool in the rotation direction are reciprocally moved in the axial direction of the tool. Since it is equipped with a supported removal unit, relatively large chips that are entwined around the cutting tool when boring or punching are moved to the tip side of the cutting tool by moving the removal unit. It can be removed from the tip of the cutting tool. In addition, since an injection hole for injecting compressed air toward the tip side of the cutting tool is provided in the removing section in the vicinity of the cutting tool, chips and relatively small chips that cannot be removed only by moving the removing section are provided. The powder can be dispersed by compressed air that is always jetted from close proximity. Therefore, the chips entwined with the turning tool bit can be reliably removed, and the working accuracy of the turning machine can be maintained constant during continuous processing.

Further, since the plurality of the injection holes are provided in the removing section so as to surround the cutting tool, compressed air can be blown around the cutting tool, and the cutting tool is not entangled by moving the removing section alone. It is possible to more reliably scatter the dust.
