2. Description of the Related Art In a honing machine for honing a machining hole of a working part by giving a rotationally driven tool an axial feed, by superposing an oscillation on the axial feed of a grinding wheel, high precision and high efficiency can be obtained. Japanese Patent No. 2602165 discloses a method of performing various honing processes. This honing machine is mounted on a main body and reciprocally driven in the feed direction, and a spindle head slidably and rotatably supported by the spindle head in the feed direction to hold a honing tool at the lower end and to move downward. A main shaft urged by a spring, a main shaft rotating motor for rotating the main shaft, and a main shaft radial direction in which the main shaft is restricted in relative rotation in a main shaft axial direction and relatively rotatably connected to the main shaft. And an arm extending to the main shaft head is periodically moved in the main spindle axis direction by a vibrator attached to the outside of the main spindle head.

[0003]

In such a honing machine, since the amplitude and speed of oscillation have a great influence on machining accuracy and efficiency, it is desired that these amplitude and speed can be easily changed. . In the above conventional invention, in order to facilitate this change, the vibrator is attached to the outside of the spindle head, and the arm extending in the radial direction is attached to the spindle for transmitting the vibration of the vibrator to the spindle. However, this causes a force from the vibrator to act on the tip of the arm at a position distant from the main spindle, which causes a moment to act on the main spindle, deteriorating the rotational accuracy of the main spindle, as well as insufficient rigidity of the arm or an increase in the mass of the main spindle. There was a problem that the vibration of the spindle head became large, resulting in deterioration of machining accuracy, efficiency, shortening of machine life, etc.

If N times / minute is set in step 6, the speed will be
Is registered in the D / A converter 68, converted into an analog signal by the D / A converter 68, amplified by the servo amplifier 69, and applied to the servo motor 43. As a result, the servomotor 43 causes the rotation shaft 41 to rotate at a rotation speed corresponding to the set oscillation speed.
The rotation is controlled so as to rotate. Servo motor 4
The actual number of revolutions of 3 is detected by the encoder and A / D
The digital value is converted by the converter 70 into the register 67.
Is registered in the control unit 65, converted into the speed of oscillation, and displayed as the speed of oscillation on the monitor screen (not shown) of the touch panel display device of the control device 65.

In the embodiment constructed as described above, when the workpiece W is mounted on the bed 1 and the start button is pressed, the spindle 10 is rotated by the motor 31 at the command speed via the pulleys 32, 30 and the belt 33. It The rotation shaft 41 of the oscillation imparting device 40 is rotationally driven by the servomotor 43 via the pulleys 44, 42 and the belt 45 at a speed N times / minute set on the operation screen 66 of the touch panel type display device. The roller 49, which is eccentrically supported from the center of rotation by the rotation of the rotating shaft 41, revolves around the rotating shaft 41 and periodically pushes the driven portion 21 that is a part of the link member 15 that abuts against the roller 49 upward. Move and link member 1
5 is given an oscillation of N times / minute. As a result, the rollers 18 a and 18 b supported by the support portions 17 a and 17 b of the link member 15 are connected to the annular groove 2 of the connecting member 25.
The side wall of 7 is periodically pushed up and down, and the main shaft 10 supported by the bearing 26 by the connecting member 25 has a speed of N times / minute.
When the amplitude S is twice the eccentricity e, the hinge pin 16 and the roller 49
Hinge pin 16 and rollers 18a, 18 relative to the distance between
Oscillation of a distance obtained by multiplying the distance ratio with b is applied. Since the rotational torque is transmitted to the main shaft 10 via the pulleys 32, 30 and the belt 33, the flexibility of the belt 33 causes the torque transmission to the main shaft 10 to resist the axial oscillation of the main shaft 10. Without spindle 10
While being rotated smoothly, it is given a smooth oscillation. Since the rollers 18a and 18b only contact the annular groove 27 of the connecting member 25 so as to be relatively displaceable in the direction perpendicular to the axis of the main shaft 10, the rollers 18a and 18b connect the connecting member 25 and the main shaft 10 to the main axis. It does not apply a force in the right direction. In particular, the swing of the link member 15 causes the rollers 18a and 18b and the annular groove 27 to relatively move in the diametrical direction of the main shaft 10 which is perpendicular to the hinge pin 16, but the rollers 18a and 18b do not move in parallel to the support shaft 1 parallel to the hinge pin 16.
Since it is freely rotatable around 9a and 19b, the main shaft 10 maintains a high rotational accuracy without applying a force in the direction perpendicular to the main shaft axis to the connecting member 25 and the main shaft 10 in the joining with the annular groove 27. be able to. Since the main shaft 10 is urged downward by the compression spring 35 via the spring bearing 36, the upper side wall of the annular groove 27 has rollers 18a,
18b, the link member 15 is urged to rotate counterclockwise in FIG. 2, and the driven portion 21 is constantly pressed by the roller 49. In this state, the spindle head is moved downward by the rotation of the servo motor 6 via the ball screw / nut mechanism 5, and is inserted into the machined hole of the workpiece W to perform honing on the inner peripheral surface of the machined hole. At this time, since the honing tool T is provided with the oscillation of the amplitude and speed suitable for machining, the machining hole is honed with high accuracy and high efficiency.

When changing the amplitude S of the oscillation,
When the knob 60 of the oscillation imparting device 40 is rotated,
The operating shaft 52 moves in accordance with the rotation direction of the knob 60 and the screw mechanism 5
8, 59 is moved back and forth in the axial direction by the wedge mechanism 54,
The support 48 is moved in the left-right direction in FIG. 4 by 55.
When the actuating shaft 52 is moved forward, the support 48 moves to the right, the eccentricity e of the roller 49 and the amplitude S increase, and when retracted, the support 48 moves to the left and the amplitude S decreases. . To change the speed N of the oscillation, the speed setting location "Oscillation" on the operation screen 66 of the touch panel display device is changed.
It is sufficient to write the number N of the desired speed in "○○ times / minute". For example, when 1000 is written, 1000 is registered in the register, and the servo motor 43 causes the rotary shaft 41 to move to 100
It rotates at a speed of 0 rpm, and the spindle 10 rotates at 100
Oscillation is given 0 times / minute.
