Abstract

PURPOSE:To readily and exactly perform the automatic clamping and unclamping of a cutting tool by clamping and unclamping the blade section clamped by a cutting tool coupled with a lock rod in the state being coupled and uncoupled freely by means of rotation of the nut of a clamping section. CONSTITUTION:A nut runner 35 is advanced to the direction of 40a to fit a joint 36 to the hexagon section 22 of a nut body 17 clamping a blade section 2 to a clamping section 3. A rotary shaft 33 is rotated in a normal direction 34a to advance the lock rod 18 screwed to the nut 17 to the direction of 40a. In the next step, the blade section 2 is moved with a robot hand gripping a V groove section 9. Then, a fitting body 8 is inserted into a fitting cylinder 16 to finally fit both of them closely by which the centering of the blade section can be done exactly.

Incidentally, cutting tool holding systems that allow easy attachment and detachment of tools have recently been proposed, in which a holder portion that directly holds a cutting tool tip is fitted into, for example, the base of a turret tool rest. However, these conventional methods not only lack rigidity but also have the disadvantage that automatic attachment/detachment operations are complicated. Moreover, NC requires complex machining functions! The rotary tool of the disk needs to be replaced, but the conventional attachment/detachment method has the disadvantage of having problems with centering accuracy and reducing the accuracy of positioning the cutting edge in the radial direction.

Then, in conjunction with the joint (to), the nut body (17)
rotate in the same direction. As a result, the locking rod α frame screwed into the nut body αη moves forward in the direction of the arrow (40a), which is the axial direction, since its rotation is regulated by the locking pin (Lj). The locking part @ of the locking rod a81 is the fitting tube αe
When the nut runner advances to a position where it protrudes from the opening, the rotation of the nut runner stops. Next, press the button, hold the V-groove (9) with the robot hand, transfer the cutting tool part (2), and insert the locking piece (c) into the long hole 0 of the cutting tool part (2) up to the hollow part αυ. Then, rotate the nut runner C39 again by 90 degrees so that the protrusion a4 of the fitting body (8) is loosely inserted into the phase determining groove (21).Next, start the nut runner C39 again and move the rotation axis (to) in the direction of the arrow ( 34b) direction, the nut body α rotates in the same direction in conjunction with the locking position (to), and the locking rod (marked 1) moves backward in the direction of the arrow (40b). Since the retaining piece (c) is engaged with the engagement end plate (1" IJ), the cutting tool part (2) moves in the direction of the arrow (40b) together with the engagement rod (1g+). In other words, the fitting body (8) is inserted into the fitting tube (IQ, and finally the two are fitted tightly, ensuring centering. At the same time, the protrusion σ is also fitted into the phasing groove (2υ), The phase of the cutting tool part (2) is determined.During this clamping process, the air hole (29) is
), (30) are supplied with compressed air. At this time, if there is a gap between the fitting body (8) and the fitting cylinder αe, that is, if the clamping is not completed, the air hole (2
9), pneumatic converter 3υ that detects the back pressure of (30),
The values of the air pressure signals 8B, 8C from the trowel are lower than the set value vA. However, when the clamping is completed, that is, when the fitting body (8) and the fitting tube (le) come into close contact, the air hole (29)
, (30) increases rapidly, and the pneumatic signals 8B and SC exceed the set value of 7 people. At the same time, the signal 8A from the torque meter (to) also exceeds the set value vT.

When SB and SC are input and the signal SA exceeds the set value vT, and the signal 8B and SC exceed the set value v people, the stop signal 8T is output to the nut runner (to) trap and the rotation of the rotation axis (to) is stopped. Then, the nut runner (to) is moved backward in the direction of the arrow (40b), and the nut (t) is separated from the nut body αη.
When replacing 2), do the same as before and replace the locking rod (1).
