A pair of support portions 21 are provided so as to be separated from each other in the X-axis direction. When the knife-breaking cassette 10 is mounted on the mounted portion 20, the knife-breaking cassette 10 is supported from below by placing a pair of supported portions 11E provided on both end portions of the mounting portion 11B, respectively. In addition, in FIGS. 8 and 9, in order to help understand the structure, the illustration of the support portion 21 that should be extended in the Z-axis direction on the near side of the drawing and that supports the supported portion 11E is omitted.

A pair of clamping portions 22 are disposed separately from each other in the X-axis direction, and are respectively disposed in the Y direction. The part of the cassette 10 for cleavage knives is clamped and fixed between the axial direction and the reference surface 24b.

More specifically, the pair of clamping portions 22 each include a contact portion 22a, The tightening timing is in contact with the front surface 12c of the pressing plate 12 of the rupture knife cassette 10; and the clamping mechanism 22d corresponds to rotating the clamping handle 22b with the rotation shaft 22c as the rotation center in the ZX plane ( See FIG. 6), the contact portion 22a is advanced and retracted in the Z-axis direction. In addition, in FIG. 6 and FIG. 7, in order to help understand the structure, the illustration of the contact portion 22 a that should be in contact with the pressing plate 12 is omitted.

On the other hand, as described above, each locking portion 15 becomes a groove portion. The locking portion 15 and the horizontal positioning portion 25 are in a state where the groove portion of the locking portion 15 and the protrusion at the front end of the horizontal positioning portion 25 are engaged (a state in which the protrusion at the front end of the horizontal positioning portion 25 is locked at the groove portion). The protrusion at the front end of the horizontal positioning portion 25 applies a spring pressure to the locking portion 15. In addition, the locking portion 15 has a U-shaped cross-section, whereby the spring force is strengthened by the contraction of the spring inside the horizontal positioning portion 25 when the locking portion 15 is about to be displaced and detached. The engaged state (engaged state) can be maintained as long as the rupture knife cassette 10 does not move in the + Z axis direction. As a result, as a result, the arrangement position of the rupture knife cassette 10 in the X-axis direction is restricted.

The cracked device 100 having the structure described above is mounted with the cracked portion 20 In the case of the knife-breaking cassette 10, first, the level of the reference surface 24a and the support portion 21 is ensured in advance, and the clamping handle 22b is rotated in the direction shown by the arrow AR2. The pair of supported portions 11E is fitted between the corresponding support portion 21 and the reference surface 24 a, and the pair of supported portions 11E is supported by the corresponding support portion 21. Thereby, positioning in the Y-axis direction (vertical direction) is completed. In this support, it is preferable that the approximate position in the X-axis direction of the locking portion 15 is first aligned with the position in the X-axis direction of the horizontal positioning portion 25.

Next, the clamp handle 22b is rotated in the direction shown by arrow AR1. With this, The pair of clamping mechanisms 22d respectively advance the abutment portions 22a in the waiting (awaiting and avoiding) state toward the -Z axis direction. As a result, the back surface 11e of the rupture knife cassette 10 abuts on the reference surface 24b, further The rupture knife cassette 10 is clamped and fixed between the abutting portion 22a and the reference surface 24b. In addition, Along with this clamping operation, one pair of locking portions 15 of the rupture knife cassette 10 arranged near the corresponding pair of horizontal positioning portions 25 in advance is engaged with the corresponding pair of horizontal positioning portions 25, respectively. With these actions, positioning in the Z-axis direction (embedding direction) and the X-axis direction (tool length direction) is completed.

By completing this clamping operation, the cassette 10 for cracking knife is completed with respect to the workpiece. The mounting and fixing of the mounting portion 20 is the fixing of the breaking blade 1 to the breaking device 100 in the aspect of this embodiment.

In addition, when removing the rupture knife cassette 10, it is only necessary to make the clamping handle 22b again. Turn it in the direction shown by arrow AR2 to release the clamped state, and it can be easily taken out.

In this way, according to the present embodiment, it is possible to fix and hold the split knife 1 in advance. The rupture knife cassette 10 is an object to be attached to and detached from the rupture device 100, and the attachment and detachment are performed by a clamping action and a release operation. Therefore, the rupture knife itself is compared with a conventional aspect in which the rupture knife itself is directly attached and detached It is possible to quickly and easily install and remove the breaking blade 1 from the breaking device 100.

In addition, as described above, in the case 10 for the rupture knife, the upper surface of the case 10 The upper surface 11c of the cassette base 11 and the blade front end 1a of the rupture knife 1 are parallel to each other. The rupture knife 1 is fixed, and the rupture knife box 10 is mounted on the mounted portion 20 of the rupture device 100 At this time, the supported portion 11E is placed on the supporting portion 21 of the mounted portion 20 which has been brought into a horizontal state in advance. That is, the cassette 10 to be a rupture knife is horizontally supported by the support portion 21. Therefore, in a state where the rupture knife cassette 10 is mounted on the mounted portion 20, the rupture knife 1 (more specifically, the blade tip 1a) must be horizontal. That is, in the breaking device 100 of the present embodiment, as long as the support portion 21 is in a horizontal state, even if no special adjustment is performed, the breaking blade 1 can be installed horizontally as long as the breaking blade box 10 is installed. .

In addition, during the clamping operation, since the supported portion 11E passes through the supporting portion, 21 is supported, and the back surface 11e is in contact with the reference surface 24b. Therefore, the mounting positions in the vertical direction and the insertion direction of the rupture knife cassette 10 are always the same.

In addition, since the locking portion 15 is engaged with the horizontal positioning portion 25 in accordance with the clamping operation, the knife-breaking cassette 10 is always the same even in the mounting position in the longitudinal direction of the knife.

That is, in the rupture device 100 of the present embodiment, as long as the rupture knife box 10 is clamped and fixed by the clamping portion 22, the rupture knife box 10 is always fixed to the rupture knife box without special positioning adjustment.

FIG. 10 is an external perspective view of a fixing jig 200 used for fixing the cracking knife 1 to the cracking knife case 10. FIG. 11 is a front view of the fixing jig 200 in a state where the cassette base 11 of the cassette 10 for cracking is mounted. FIG. 12 shows a state where the rupture knife cassette 10 which is fixedly holding the rupture knife 1 is mounted. Front view of fixture 200. In addition, in FIG. 10 to FIG. 12, right-hand xyz coordinates in which the zx plane is a horizontal plane and the y-axis direction is a vertical direction are marked. In FIGS. 10 to 12, in order to facilitate the operation, the front surface (front view surface) of the fixing jig 200 is set to be parallel to the xy plane. In addition, FIG. 13 is a diagram showing a procedure of fixing the rupture knife 1 to the rupture knife cassette 10 using the fixing jig 200.

The fixing jig 200 includes: a base 200a placed on a predetermined horizontal plane; The main body portion 200b is erected perpendicularly to the base portion 200a and is a thick plate portion having a right-angled triangular shape having a thickness in the z-axis direction, and an inclined surface 201 inclined from the y-axis direction at a predetermined angle θ in the xy plane becomes the upper surface And an extending portion 200c that extends perpendicular to the inclined surface 201 in the xy plane. The extension portion 200c has a reference surface 202 that is perpendicular to the inclined surface 201 and parallel to a main surface 200d, which is a right-angled triangular shape of the main body portion 200b.

The reference plane 202 is similar to the inclined plane 201 at an angle θ from the y-axis direction. The oblique direction has a long side direction. As a result, the inclined plane 201 and the reference plane 202 are L-shaped in cross section perpendicular to the longitudinal direction. The reference surface 202 serves as a reference in the overlapping direction of the three members when the breaking blade 1 is clamped and fixed between the cassette base 11 and the pressing plate 12. In the following, for convenience, the direction inclined from the y-axis direction at an angle θ is referred to as the jig long side direction. In addition, the reference surface 202 has a positioning pin 202a for a cassette base standing in the z-axis direction near an end portion on the lower side in the longitudinal direction of the jig.

The details are described below, and in the fixing jig 200, the inclined surface 201 and the base The section formed by the quasi-plane 202 is L-shaped when viewed in cross section, and serves as a mounting portion of the cleaving knife cassette 10. The cleaving knife cassette 10 is placed along the longitudinal direction of the jig.

In addition, a pair of cassette clips are provided on a main surface (side surface) 200d of one of the main body portions 200b. 203. The pair of cassette holders 203 are provided so as to be separated from each other in the longitudinal direction of the jig. The pair of cassette clamps 203 are each provided with: an abutting portion 203a that can move forward and backward in the z-axis direction; and a clamping mechanism 203d that corresponds to the clamping handle 203b with the rotation axis 203c as the rotation center and is perpendicular to the xy plane The rotation in the plane makes the abutting portion 203a advance and retreat in the z-axis direction.

Specifically, the abutting portion 203a is in a state where the cracking knife cassette 10 is placed. The clamping handle 203b is rotated in the direction indicated by AR3 in FIG. 10 to abut against the front surface 12c of the pressing plate 12 of the rupture knife cassette 10. Thereby, the state which the rupture knife cassette 10 is fixedly hold | maintained to the fixing jig 200 is implement | achieved. In addition, as described below, the clamping operation in the actual use situation is performed in a state where the overlapped body before being fixed by screwing with the fixing screw 13 is placed.

On the other hand, if the clamping handle 203b is moved to AR4 in FIG. Rotating in the direction releases the contact state of the contact portion 203a with respect to the front face 12c.

For the use of the fixing jig 200 having the above-mentioned structure to break the knife 1 First, only the cassette base 11 is mounted on the mounting portion of the fixing jig 200 (step S1). FIG. 11 shows the appearance of the placement. Specifically, the cassette base 11 is configured such that the upper surface 11c of the cassette base 11 abuts on the inclined surface 201, the rear surface 11e of the cassette base 11 abuts on the reference surface 202, and the end portion in the longitudinal direction further contacts the positioning pin 202a for the cassette base. Placed like this. At this time, the abutment of the cassette base 11 with the cassette base positioning pin 202a with respect to the inclined surface 201 is realized by the weight of the cassette base 11 itself.

Next, the cleaving knife 1 is disposed on the surface 11a of the cassette base 11 thus placed (step Step S2). The breaking blade 1 is arranged such that the blade tip 1a faces upward. In the arrangement of the breaking knife 1, the surface 11 b of the cassette base 11 is inclined, and the positioning pins 14 a for the breaking knife provided in the cassette base 11 are located near the lower end of the jig in the longitudinal direction. That is, the split knife 1, and the surface 11b and The arrangement relationship of the positioning pins 14a for the split knife is similar to the arrangement relationship of the cassette base 11 and the inclined surface 201 and the cassette base positioning pins 202a. Therefore, the abutment of the cracking blade 1 with respect to the surface 11b and the positioning pin 14a for the cracking blade is a self-implementation.

Next, the pressing plate 12 is superposed on the breaking blade 1 (step S3), but When the pressing plate 12 is placed, the arrangement relationship between the pressing plate 12 and the surface 11b and the positioning pin 14b for the pressing plate is similar to the arrangement relationship of the cassette base 11 and the inclined surface 201 and the positioning pin 202a for the cassette base. Therefore, the contact of the pressing plate 12 with respect to the surface 11b and the positioning pin 14b for the pressing plate is also achieved by oneself.

When the configuration of the split knife 1 and the pressing plate 12 is completed as above, then Next, the cassette gripper 203 is clamped by rotating the clamp handle 203b in a direction indicated by an arrow AR3 (step S4). By this clamping, the overlapping body in which the rupture blade 1 is sandwiched between the cassette base 11 and the pressing plate 12 is clamped and fixed between the reference surface 202 and the contact portion 203 a of the cassette holder 203. In the clamped and fixed state, the box base 11 is abutted on the reference surface 202, and the rupture blade 1 and the pressing plate 12 overlapped thereon are also sequentially contacted. Therefore, as a result, the box base The seat 11, the cutting blade 1, and the pressing plate 12 are positioned with reference to the reference surface 202.

Then, in the state where the clamping is completed, the fixing screw 13 is screwed from the front surface 12c side of the pressing plate 12 to clamp and fix the breaking blade 1 between the cassette base 11 and the pressing plate 12 (step S5). ). Then, when the clamping and fixing are completed, the clamping of the cassette holder 203 is released (step S6). Thereby, the rupture knife cassette 10 in which the rupture knife 1 is fixedly held can be obtained.

According to the above sequence, the fixing screw 13 is fixed under the condition that the breaking blade 1, the box base 11 and the pressing plate 12 are always arranged at the same position, and therefore, the box base 11 and the pressing plate 12 are clamped. Of course, the fixed position of the cracking knife 1 during fixing is always the same. also That is, even if the rupture knife 1 is replaced, the fixed position of the rupture knife 1 in the rupture knife cassette 10 is reproduced. In addition, the screw stop of the fixing screw 13 is intended for a person who is clamped and fixed by a clamping operation in advance. Therefore, when a force is applied to the screw, positional displacement of the pressing plate 12 or the breaking blade 1 can be avoided.

That is, if the fixing jig of the present embodiment is used, when the cracking knife is attached to the cracking device by clamping and fixing the cracking knife cassette holding the cracking knife in advance, it is possible to Fixation of the rupture knife to the rupture knife cassette is performed with good reproducibility.
