The cutting device includes a blade cooler nozzle and a shower nozzle. When cutting the workpiece with the cutting blade, the cutting device cools the processing heat generated by cutting by supplying cutting water from the blade cooler nozzle and the shower nozzle. The cutting chips generated by cutting are discharged from the upper surface of the workpiece (for example, refer to Patent Document 1 below).

Since the machining precision changes depending on the position of the blade cooler nozzle or the shower nozzle with respect to the cutting blade, it is necessary to adjust the position of the blade cooler nozzle or the shower nozzle according to the thickness of the cutting blade, the outer diameter size, or the like. In particular, in the case where a plurality of workpieces are required to have the same machining accuracy by using a plurality of cutting devices, it is difficult to adjust the position of the blade cooler nozzle or the shower nozzle while grasping the position of the cutting blade during the cutting operation. It was difficult to set at the same position in the apparatus.

That is, the removal means 70 on the side with the shower nozzle 42 on the side of the spindle 31 to be picked up is raised, and the removal means 70 on the opposite side is retracted downward, and the cutting liquid 43 is removed. Dry air is blown from the air injection port 71 of the removal means 70 in the same direction as the injection direction to remove the cutting liquid 43 attached to the second window portion 63. In the case of imaging while spraying cutting fluid 43, it turns out that cutting fluid 43 rotates with the rotation of the spindle 31, and the degree of scattering of cutting fluid 43 with respect to the cutting blade 33 becomes unclear. In order to prevent it, it is preferable not to rotate the spindle 31.

The switching means 65 shown in FIG. 5 moves the switching mirror 650 by the rotation mechanism 651 to the predetermined angle inclined position shown by the dotted line of FIG. 5 on the optical path of the condensing lens 612. In this way, the light emitted from the light source 66 is guided to the first optical path 64a by the switching mirror 650, passes through the first window portion 62, and is reflected by the imaging region P. The imaging element of the camera 610 receives the reflected light, thereby photoelectrically converting the subject image to form the captured image 100 shown in FIG. 7. The captured image 100 is displayed on the display monitor 18. In addition to the captured image 100, the display monitor 18 includes, for example, a distance (1 mm) between two lines of dotted lines indicating the height of the blade cooler nozzle 41, or the injection port 42a of the shower nozzle 42. The angle θ (62.6 °) indicating the direction of is also indicated. The blade tip position of the cutting blade 33, the height position of the blade cooler nozzle 41, the height position and the angle of the shower nozzle 42 are connected to the captured image 100 by the control means of the cutting device 1, for example. Detected on the basis of The control means automatically identifies the cutting edge position of the cutting blade 33, the height position of the blade cooler nozzle 41, the height position and angle of the shower nozzle 42, and the like from the captured image 100, and the cutting blade. The position of the blade edge | tip of 33, the height position of the blade cooler nozzle 41, and the height position of the shower nozzle 42 may be designated by the operator on the display monitor 18, and a control means may calculate a distance or an angle. .

When the angle θ of the shower nozzle 42 imprinted on the captured image 100 is not a predetermined angle, the operator adjusts the angle adjusting screw 55 by the angle adjusting screw 55 while viewing the captured image 100. The angle of the shower nozzle 42 is adjusted by loosening and adjusting the direction of the shower nozzle 42 to predetermined angle (theta), and tightening the angle adjusting screw 55 after that. Moreover, for example, when the height position of the shower nozzle 42 becomes high with respect to the blade edge | tip of the cutting blade 33, an operator connects with the height position adjustment screw 54, visually acknowledging the captured image 100. FIG. The shower nozzle 42 is lowered together with the block 51c to adjust to a predetermined height position.

In addition, for example, when the height position of the blade cooler nozzle 41 imprinted on the picked-up image 100 is lower than the blade tip of the cutting blade 33, an operator will recognize the picked-up image 100, and will height-adjust the screw By 53, the blade cooler nozzle 41 is raised together with the connection block 51b to adjust to a predetermined height position. Here, the desired height of the blade cooler nozzle 41 is lower than the outer periphery of the nut 36 so that the blade cooler nozzle 41 does not interfere with the nut 36, and the cutting blade 33 is worn. In order to prevent the blade cooler nozzle 42 from contacting the upper surface of the workpiece even when the blade tip is shortened, the lower end of the blade cooler nozzle 41 represented by one dotted line S1 in FIG. 7 is the other dotted line S2. It adjusts so that it may become upper side than the outer periphery of the front side flange 35 shown by this. In addition, when adjusting the height position of the blade cooler nozzle 41, it is not necessary to spray cutting fluid from the blade cooler nozzle 41. FIG. Since the cutting liquid injected toward the front and back of the cutting blade 33 by the blade cooler nozzle 41 is supplied to the machining point via the flange or the cutting blade 33, the blade cooler nozzle 41 itself is a nut. (36) or a position which is not in contact with the workpiece. Therefore, it is not necessary to adjust the position of the blade cooler nozzle 41 while supplying cutting fluid from the blade cooler nozzle 41 to the cutting blade 33.

When imaging the subject from below through the second window portion 63 using the captured image forming unit 60, the switching means 65 shown in FIG. 5 is switched mirror 650 by the rotation mechanism 651. Is evacuated from the optical path of the condenser lens 612 to the position shown by the solid line in FIG. As a result, the light emitted from the light source 66 is guided to the second optical path 64b and passes through the second window portion 63, and is reflected from the blade edge of the cutting blade 33 and the lower side of the shower nozzle 42. . The imaging element of the camera 610 receives the reflected light, thereby photoelectrically converting the subject image to form the captured image 200 shown in FIG. 8. The captured image 200 is displayed on the display monitor 18. In addition to the picked-up image 200, the display monitor 18 also shows the distance (0.1 mm) which shows the position shift amount of the center of the cutting blade 33 and the center of the injection port 42a of the shower nozzle 42, for example. Are marked together. The position of the shower nozzle 42 in the Y-axis direction is detected based on the picked-up image 200 by the control means of the cutting device 1, for example. In addition to the automatic determination by the control means, the position of the shower nozzle 42 in the Y-axis direction may be designated by the operator on the display monitor 18 as a predetermined value and calculated by the control means.

In the present embodiment, the center line L1 passing through the center of the injection port 42a of the shower nozzle 42 taken on the captured image 200 and the center line L2 passing through the center of the cutting blade 33 are shifted. In that point, the operator loosens the position adjusting screw 56 shown in FIG. 3 while visualizing the captured image 200, and then moves the shower nozzle 42 in the Y-axis direction, thereby causing the center line L1 and the center line L2 to move. ), The position of the shower nozzle 42 in the Y-axis direction is adjusted to coincide. After that, tighten the positioning screw 56.

When adjusting the position and angle of the shower nozzle 42, the state which sprays cutting fluid from the injection port 42a of the shower nozzle 42 is preferable. When the center of the shower nozzle 42 is displaced from the center of the cutting blade 33, the amount of the cutting fluid supplied to the front and back surface side of the cutting blade 33 is broken, which causes bending (meandering) of the cutting blade 33. Since there is a fear, the position of the shower nozzle 42 can be adjusted with good accuracy by imaging the state in which the cutting liquid is jetted from the injection port 42a with the camera 610. In addition, you may adjust a nozzle, spraying cutting fluid from the shower nozzle 42, and after adjusting the position and angle of the shower nozzle 42 once, the state which cutting liquid was injected is imaged again by the imaging means 61, You may check it.

Thus, the picked-up image forming unit 60 which concerns on this invention is the imaging means 61 containing an imaging element, the front surface 330 or back surface 331 of the cutting blade 33, and the blade cooler nozzle 41. The first optical path 64a reaching the first window portion 62 facing from the imaging means 61 and the outer circumferential tip of the cutting blade 33 and the shower nozzle 42 from the outer circumferential direction of the cutting blade 33. Since the second window portion 63 facing face was provided with a second optical path 64b reaching from the imaging means 61, and switching means 65 for switching the first optical path 64a and the second optical path 64b. In one captured image forming unit 60, the cutting blade 33, the blade cooler nozzle 41, and the shower nozzle 42 can be captured in the same captured image. Therefore, according to the present invention, the nozzle adjustment can be easily performed based on the thickness and the position of the cutting blade 33.

In addition, the order of nozzle adjustment is not specifically limited. After adjusting the position of the blade cooler nozzle 41, you may adjust the position and angle of the shower nozzle 42, and after adjusting the position and angle of the shower nozzle 42, the position of the blade cooler nozzle 41 is adjusted. You may adjust.

Although the picked-up image 100 and 200 shown in the said embodiment was used at the time of nozzle adjustment, For example, the blade cooler nozzle 41 and the shower nozzle 42 are picked up regularly, and a picked-up image is recorded to the recording part 19. FIG. You may record. If the captured image picked up through the first window part 62 or the second window part 63 is recorded in the recording medium of the recording part 19, it can be used as image data for management recording of the cutting device 1, for example. . By using the captured image recorded on the recording medium, the positions of the blade cooler nozzle 41 and the shower nozzle 42 in the plurality of cutting devices 1 can be set to the same setting.

Although the picked-up image forming unit 60 shown in the said embodiment was made into the structure independent from the cutting device 1, you may mount the picked-up image forming unit 60 in the apparatus.
