Can be fixed. Further, the plate thickness can be detected while the work W is being pressed.

In order to prevent the X-axis ball screw 49 from bending due to its own weight, the ball screw 49 is normally supported from below, and when the cutting head 47 passes, the ball screw 49 is retracted to the rear side to perform cutting. A plurality of screw support devices 57 that avoid interference with the head 47 are provided in the left-right direction at appropriate intervals.

On the side surface of the side plate 5 on the right side of the V-grooving machine 1, one end of an inverted concave arm 59 having a horizontal portion higher than the height of the side plate 5 should be attached so as to be rotatable by an allowable angle. At the other end of the arm 59, there is provided an operation panel 61 which is rotatable around a vertical axis by an allowable angle. Therefore, the operation panel 61 can be moved to the left and right within an allowable range, and its operation surface can be oriented in a direction that is easy for the operator to see.

With the above configuration, when the X-axis drive motor M _x is driven, the drive pulley 65 is rotated via the output shaft 63. The rotation of the drive pulley 65 causes the ball screw 49 to rotate via the timing belt 71 and the driven pulley 69. The rotation of the ball screw 49 causes the cutting head 47 to move in the X-axis direction via the nut member 73.

As shown in FIG. 2, a drive pulley 75 is attached to the output shaft of the Z-axis drive motor M _z , and a driven pulley 77 is attached to the tip of the ball screw 53 by a key. Has been. A timing belt 79 is wound around the driven pulley 77 and the drive pulley 75. A nut member 81 is screwed onto the ball screw 53, and the slider 43 is attached to the nut member 81. The cutting head 47 is provided with two guide rails 83 extending in the Z-axis direction.

With the above configuration, when the Z-axis drive motor M _z is driven, the ball screw 53 is rotated via the drive pulley 75, the timing belt 79, and the driven pulley 77. By rotating the ball screw 53, the slider 43 is moved in the Z-axis direction while being guided by the guide rail 83 via the nut member 81.

An indexing table 41 is rotatably supported below the slider 43. That is, as the slider 43 is shown in FIG. 2, indexing drive motor M _A, such as a servomotor through a bracket 85 is provided with an output shaft of the indexing drive motor M _A A drive pulley 87 is attached to the drive pulley 87, and a driven pulley 89 is attached to the axial center of the indexing table 41.

A plurality of sets of cutting tool holders 39 are provided on the circumference of the indexing table 41 at appropriate intervals. In this embodiment, as shown in FIG. 2, for example, three sets of cutting tool holders 39A, 39B, 39C are attached. The cutting tool holder 39A has three cutting tools (also referred to as bites) 37 for performing groove processing, and the succeeding cutting tool 37 cuts deeper than the preceding cutting tool 37. As you can see, it is projected downward. The cutting tool holder 39B is provided with three cutting tools 37 for performing a parting process on the work W, so that the succeeding cutting tool 37 cuts deeper than the preceding cutting tool 37. It is projected downward. Similarly, the cutting tool holder 39C is provided with five cutting tools 37 for performing cutting processing such as V groove processing or concave groove processing on the work W, which is succeeding to the preceding cutting tool 37. The cutting tool 37 of No. 2 is projected downward so as to cut deeper.

A piston 97 is provided in the hydraulic cylinder 99 on the right side of the rotary shaft 93 in FIG. 1 via a high-load disc spring 95, for example. Moreover, the thrust bearing 101 is rotatably supported on the right side of the piston 97 in the hydraulic cylinder 99. Further, a roller bearing 103 is attached to the right end of the rotary shaft 93, and a cylinder cap 105 is provided on the outer peripheral portion of the roller bearing 103.

With the above configuration, the rotary shaft 93 of the driven pulley 89 is normally pressed by the urging force of the disc spring 95 to the right in FIG. When indexing the indexing table 41, for example, by supplying hydraulic pressure as indicated by an arrow, the rotary shaft 93 is moved to the left side in FIG. 1 against the biasing force of the disc spring 95, A minimum amount of space is floated between the slider 43 and the indexing table 41 to reduce frictional resistance and rotate. Therefore, by using the high-load disc spring 95, it is possible to prevent chatter and rattling due to cutting resistance.

As shown in FIG. 1, under the slider 43, an ID chip detector 107 is provided, and a plurality of sets of, for example, cutting devices provided on the outer circumference of the indexing table 41 are provided. Each ID chip 109 is embedded at a position corresponding to the ID chip detector 107 at the rear part (right part in FIG. 1) of the tool holder 39A, 39B, 39C. A through hole 111 is formed in the indexing table 41 at a position where the ID chips 109 and the ID chip detector 107 correspond to each other, as shown in FIG. Further, the ID chip detector 107 is connected to the NC device provided in the operation panel 61.

In the ID chips 109, reference numbers and types (for example, V-groove bite, groove bite, concave groove bite, end face machining) of the cutting tools 37 attached to the cutting tool holders 39A, 39B, 39C are provided. Cutting tool), accumulated cutting distance, and other management data of the cutting tool are stored. These management data are read by the ID chip detector 107 and stored in the memory of the NC device.

With the above configuration, when the selected cutting tool holder is indexed and positioned at the machining position, the management data stored in the ID chip 109 mounted on this cutting tool holder is stored in the ID chip detector. It is read by 107 and transferred to the NC device.

The NC device recognizes whether the cutting tool used in the program to be machined matches the management data previously stored in the NC device, and outputs an alarm if they do not match. When they match, the work W is subjected to the necessary groove processing with the cutting tool. Then, the integrated cutting distance updated each time the machining program ends is written in each ID chip 109 of the cutting tool holder.

Therefore, it is possible to check the difference in the types of cutting tools due to programmer mistakes. In addition, the wearability and operating rate of the cutting tool can be controlled by the cumulative cutting distance. That is, the complexity of managing the cutting tool can be eliminated, and the degree of wear can be estimated, so that the cutting tool can be efficiently replaced. In addition, machining with worn cutting tools can be avoided.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes.
