In FIG. 8, first, after the operator of the device turns on the power switch, the number of workpieces to be processed and the machining mode are input by the operation buttons on the operation panel 8 and the start button is pressed. , The arm of the articulated robot 3 is moved to the initial position (S1), the number of workpieces to be processed is set (S3), and the setting items are extracted from the processing mode data table 24b based on the input processing mode (S5). ), The ultrasonic processing program described later is executed (S7).

(First machining mode)
First, it is explained that the first machining mode for machining the work W is set by urging the cutter blade 69 with the cutter blade angle urging cylinder 75 and the cutter blade position urging cylinder 79 turned on. do. The first machining mode is the optimum machining mode when machining a work W having a complicated machining shape.

In FIG. 9, in the ultrasonic machining program, first, after acquiring machining data from the machining data table 24a (S21), it is determined whether or not the machining mode is the cutter blade angle urging mode (S23).

Since the first machining mode uses the cutter blade angle urging mode (S23: Yes), the first cutter blade angle urging cylinder 75a and the second cutter blade angle urging cylinder 75b are turned on (S23: Yes). S25), it is determined whether or not the machining mode is the cutter blade position urging mode (S29).

Since the first machining mode uses the cutter blade position urging mode (S29: Yes), the first cutter blade position urging cylinder 79a and the second cutter blade position urging cylinder 79b are used. It is turned on (S31).

In FIG. 4 described above, the first cutter blade angle urging cylinder 75a and the second first cutter blade angle urging cylinder 75b are turned on, and no load is applied to the cutter blade (angle 0). Degree) is shown.

Specifically, with reference to FIG. 4, the first cutter blade angle urging cylinder 75a is turned on, and air flows from the air compressor 14 via the connecting tube 23 to the first cutter blade angle urging cylinder. When injected into the gap 21 of the first housing 17 of 75a, the piston 19 is lowered to the upper and lower sides of the drawing, and a third protrusion 87 connected to the tip of the piston 19 is provided on the rotating body 13. It abuts on the protrusion 83 of 1.

Further, the second cutter blade angle urging cylinder 75b is turned on, and air flows from the air compressor 14 via the connecting tube 31 to the gap portion of the second housing 25 of the second cutter blade angle urging cylinder 75b. When injected into 29, the piston 27 rises upward on the drawing, and the fourth protrusion 89 connected to the tip of the piston 27 abuts on the second protrusion 85 provided on the rotating body 13.

In this way, when the first cutter blade angle urging cylinder 75a and the second first cutter blade angle urging cylinder 75b are turned on, the rotating body 13 rotates clockwise with respect to the base shaft 11 in the drawing. Although rotatable in the direction and counterclockwise direction, the rotating body 13 is urged by a third protrusion 87 connected to the tip of the piston 19 and a fourth protrusion 89 connected to the tip of the piston 27. As a result, if no load is applied to the cutter blade 69, the cutter blade 69 is in a stable state at a position at an angle of 0 degrees (see FIG. 13).

After returning to the ultrasonic machining program and completing the setting of the machining mode, it is determined whether or not the work W is set on the work setting table 16 (S35), and the work W is set on the work setting table 16. If not (S35: No), wait until the work W is set on the work installation table 16, and if the work W is set on the work installation table 16 (S35: Yes), connect to the cutter blade 69. The oscillator 2 is driven in order to ultrasonically vibrate the oscillator 71 (S37).

Next, each arm of the articulated robot 3 is moved (S39) so that the cutter blade 69 is located at the machining start position with respect to the work W, and the cutter blade 69 is moved to ultrasonically machine the work W (S41). ).

Here, in the first processing mode in which the cutter blade 69 is urged to process the work W with the cutter blade angle urging cylinder 75 and the cutter blade position urging cylinder 79 turned on, the work processing apparatus 5 The internal operation will be described.

FIG. 10 shows a state in which the cutter blade angle urging cylinder is turned on, a load is applied to the cutter blade, and the cutter blade is rotated by a maximum angle in the counterclockwise direction (angle + θ1 degree) in the BB sectional view of FIG. 11 is a state in which the cutter blade angle urging cylinder is turned on, a load is applied to the cutter blade, and the cutter blade is rotated by the maximum angle in the clockwise direction in the BB sectional view of FIG. It is a figure which shows (angle −θ1 degree), and FIG. 13 is a figure which looked at the attached cutter blade from the lower side, and is the explanatory view explaining the relationship between the cutter blade and the rotation direction of a cutter blade.

As described above, FIG. 4 shows a state in which no load is applied to the cutter blade 69, but in the first machining mode, the cutter blade 69 rotates from the work W during the work W machining of the work machining apparatus 5. When a load is applied, the cutter blade 69 is configured to be rotatable within a range of ± several degrees (maximum ± 5 °).

However, the rotating body 13 has a third protrusion 87 connected to the tip of the piston 19 by turning on the first cutter blade angle urging cylinder 75a and the second cutter blade angle urging cylinder 75b. Abuts on the first protrusion 83 provided on the rotating body 13, and the fourth protrusion 89 connected to the tip of the piston 27 hits the second protrusion 85 provided on the rotating body 13. It is correct that by touching the cylinder, it is always urged toward a position at an angle of 0 degrees (see FIG. 13), and it can rotate in that state.

For example, as shown in FIG. 10, a rotational load is applied to the cutter blade 69 with the first cutter blade angle urging cylinder 75a and the second cutter blade angle urging cylinder 75b turned on. When the first protrusion 83 provided on the rotating body 13 keeps pushing the third protrusion 87 connected to the tip of the piston 19, and the cutter blade 69 rotates the maximum angle in the counterclockwise direction on the drawing ( At an angle + θ1 degree), the first protrusion 83 provided on the rotating body 13 abuts on the third protrusion 87 connected to the tip of the piston 19, but the second protrusion provided on the rotating body 13 is provided. The protrusion 85 does not abut on the fourth protrusion 89 connected to the tip of the piston 27.

When the first protrusion 83 provided on the rotating body 13 keeps pushing the third protrusion 87 connected to the tip of the piston 19, the first protrusion abuts on the third protrusion 87. The portion 83 is urged from the third protrusion 87 in the −θ direction by a force of f1. The force f1 does not change depending on the angle of the rotating body 13, but is constant as long as the first protrusion 83 abuts on the third protrusion 87.

On the other hand, for example, as shown in FIG. 11, a rotational load is applied to the cutter blade 69 with the first cutter blade angle urging cylinder 75a and the second cutter blade angle urging cylinder 75b turned on. When the second protrusion 85 provided on the rotating body 13 keeps pushing the fourth protrusion 89 connected to the tip of the piston 27, and the cutter blade 69 rotates the maximum angle in the clockwise direction on the drawing. At (angle −θ1 degree), the second protrusion 85 provided on the rotating body 13 abuts on the fourth protrusion 89 connected to the tip of the piston 27, but is provided on the rotating body 13. The first protrusion 83 does not abut on the third protrusion 87 connected to the tip of the piston 19.

When the second protrusion 85 provided on the rotating body 13 continues to push the fourth protrusion 89 connected to the tip of the piston 27, the second protrusion abuts on the fourth protrusion 89. The portion 85 is urged from the fourth protrusion 89 in the + θ direction by a force of f1. Note that this force f1 does not change depending on the angle of the rotating body 13, and is constant as long as the second protrusion 85 abuts on the fourth protrusion 89.

FIG. 14 is a diagram showing a state (angle + X1 mm) in which the cutter blade position urging cylinder is turned on, a load is applied to the cutter blade, and the cutter blade is maximally displaced in the + X direction in the CC sectional view of FIG. 15 shows a state in which the cutter blade position urging cylinder is turned on, a load is applied to the cutter blade, and the cutter blade is displaced by the maximum displacement in the −X direction (angle-) in the CC sectional view of FIG. It is a figure which shows X1mm).

As described above, FIG. 5 shows a state (position 0 mm) in which the first cutter blade position urging cylinder 79a and the second cutter blade position urging cylinder 79b are turned on and no load is applied to the cutter blade. However, in the first machining mode, when the cutter blade 69 receives a load from the work W during the machining of the work W of the work machining apparatus 5, the cutter blade 69 is ± several mm (maximum ± 5 mm). It is configured to be movable within the range of.

However, in the moving body 90, the seventh protrusion 97 provided on the moving body 90 is formed by turning on the first cutter blade position urging cylinder 79a and the second cutter blade position urging cylinder 79b. The eighth protrusion 98 provided on the moving body 90 abuts on the fifth protrusion 95 connected to the tip of the piston 47, and hits the sixth protrusion 99 connected to the tip of the piston 55. It is correct that the contact is always in a state of being urged toward the position of 0 mm (see FIG. 14), and it is possible to move in that state.

For example, as shown in FIG. 14, a load is applied to the cutter blade 69 with the first cutter blade position urging cylinder 79a and the second cutter blade position urging cylinder 79b turned on, and the moving body 90 When the eighth protrusion 98 provided in the above continues to push the sixth protrusion 99 connected to the tip of the piston 55 and the cutter blade 69 moves the maximum displacement in the + X direction (angle + X1 mm), the moving body 90 The eighth protrusion 98 provided on the moving body 90 abuts on the sixth protrusion 99 connected to the tip of the piston 55, while the seventh protrusion 97 provided on the moving body 90 abuts on the tip of the piston 47. Does not abut on the fifth protrusion 95 connected to.

If the eighth protrusion 98 provided on the moving body 90 continues to push the sixth protrusion 99 connected to the tip of the piston 55, the eighth protrusion abuts on the sixth protrusion 99. The portion 98 is urged from the sixth protrusion 99 in the −X direction by a force of f2. Note that this force f2 does not change depending on the position of the moving body 90, but is constant as long as the eighth protrusion 98 abuts on the sixth protrusion 99.

On the other hand, for example, as shown in FIG. 15, a load is applied to the cutter blade 69 and the cutter blade 69 moves while the first cutter blade position urging cylinder 79a and the second cutter blade position urging cylinder 79b are turned on. When the seventh protrusion 97 provided on the body 90 keeps pushing the fifth protrusion 95 connected to the tip of the piston 47, and the cutter blade 69 moves the maximum displacement in the −X direction (angle −X1 mm). The seventh protrusion 97 provided on the moving body 90 abuts on the fifth protrusion 95 connected to the tip of the piston 47, but the eighth protrusion 98 provided on the moving body 90 is , Does not abut on the sixth protrusion 99 connected to the tip of the piston 55.

If the seventh protrusion 97 provided on the moving body 90 continues to push the fifth protrusion 95 connected to the tip of the piston 47, the seventh protrusion abuts on the fifth protrusion 95. The portion 97 is urged from the fifth protrusion 95 in the + X direction by a force of f2. Note that this force f2 does not change depending on the position of the moving body 90, but is constant as long as the seventh protrusion 97 abuts on the fifth protrusion 95.

The work W is processed so as to be urged.

Then, it is determined whether or not the machining of the work W is completed (S43), and if the machining of the work W is not completed (S43: No), the movement (machining) of the cutter blade 69 is continued (S41). ), When the machining of the work W is completed (S43: Yes), the process returns to the main program (S45).

(Third machining mode)
Next, a third machining mode for machining the work W by urging the cutter blade 69 with the cutter blade angle urging cylinder 75 and the cutter blade position locking cylinder 81 turned on will be described. The third machining mode is also an appropriate machining mode when machining a work W having a complicated machining shape, but is used when machining at a higher speed than the first machining mode.

Since the third machining mode uses the cutter blade angle urging mode (S23: Yes), the first cutter blade angle urging cylinder 75a and the second cutter blade angle urging cylinder 75b are turned on (S23: Yes). S25), it is determined whether or not the machining mode is the cutter blade position urging mode (S29).

Since the third machining mode does not use the cutter blade position urging mode (S29: No), the cutter blade position locking cylinder 81 is turned on (S33).

FIG. 16 is a diagram showing a state (displacement 0 mm) in which the cutter blade position locking cylinder is turned on and the position of the cutter blade is fixed in the CC cross-sectional view of FIG.

Specifically, with reference to FIG. 16, the cutter blade position locking cylinder 81 is turned on, and air flows from the air compressor 14 via the connecting tube 94 and the connecting tube 96 to the sixth cylinder 81 for locking the cutter blade position. When injected into the gap portion 65 of the housing 61, the piston 63 moves to the left side in the drawing, and the lock pin 67 connected to the tip of the piston 63 fits into the recess 93 provided in the moving body 90.

In this way, when the cutter blade position locking cylinder 81 is turned on, the moving body 90 is fixed by the lock pin 67, and the cutter blade 69 is fixed at the position 0 mm (see FIG. 16 and the like).
