A plurality of stamps are made on the surface of 200 to create a desired image.

  As described above, the fixing jig 120 in the engraving machine 100 is configured to be simply sandwiched between the plate members 142a and 142b extending in the X-axis direction. For example, the workpiece 200 has a rectangular parallelepiped shape. If so, the surfaces of the workpiece 200 and the plate members 142a and 142b that are in contact with each other are parallel, and the workpiece 200 can be reliably fixed by the fixing jig 120. That is, in this case, since the plate member 142a, 142b and the workpiece 200 are in large contact with each other, the workpiece 200 can be reliably fixed by the fixing jig 120.

  However, for example, if the workpiece 200 is a conical shape, the workpiece 200 and the plate members 142a and 142b do not have parallel surfaces that contact each other. Could not be fixed. That is, in this case, it is difficult to securely fix the workpiece 200 with the fixing jig 120 because the surface where the plate members 142a and 142b and the workpiece 200 abut is small.

  As a result, the shape of the workpiece 200 on which the image can be formed in the stamping machine 100 is limited, and the stamping machine 100 can form an image only on the workpiece 200 having a limited shape. Met.

For this reason, the proposal of the fixing jig which can fix the workpiece of many kinds of shapes reliably was desired.

  At this time, the screw shafts 64a and 66a of the screws 64 and 66 penetrate the plate-like member 56, respectively, and also penetrate the long holes 52-1a and 52-1b provided in the connection portion 52-1 of the pressing plate 52. ing. Further, the screw shaft 68a of the screw 68 reaches only the plate member 56 without passing through the plate member 56 and reaching the other plate member 50-2 of the hinge 50 (see FIG. 6). ).

  Thus, the pressing plate 52 is disposed so as to be rotatable about the screw shaft 68 c of the screw 68. That is, in other words, the pressing plate 52 is disposed so as to be rotatable around the Y axis.

  The rotation range depends on the length L3 of the long axis of the long holes 52-1a and 52-1b, and can be rotated in the arrow A direction and the arrow B direction in this rotation range. (See FIG. 9).

  Further, the hinge 50 is provided with a winding spring 54 on the rotation shaft 50-3, and this winding spring is in a state where one plate member 50-1 of the hinge 50 is fixedly arranged on the slide member 16. 54, the other plate member 50-2 is urged in the direction of arrow C, whereby the pressing portion 52-2 of the pressing plate 52 is urged downward.

That is, the hinge 50 is rotatable around the X axis, and the pressing plate 52 provided on the other plate member 50-2 of the hinge is always urged in the direction of arrow C by the winding spring 54. is there.

  The fixing jig 10 having the above configuration is installed in the stamping machine 100, and the workpiece 200 is fixed to the fixing jig 10 when a predetermined image is stamped on the workpiece 200 by the stamping machine 100. The work will be described.

  First, in the fixing jig 10, the operator picks the knob portion 52-2 d, lifts the pressing plate 52 upward against the urging force of the winding spring 54, and between the pressing member 20 and the base member 18. The workpiece 200 is formed so that the processing surface is directed upward in the space and the processing surface is positioned in the opening 52-2a formed in the pressing portion 52-2 of the pressing member 20. Place.

  At this time, by placing the central axis of the workpiece 200 so as to be positioned on the groove 18-1e, the resin member 52-2b, 52-2c provided on the pressing plate 52 of the pressing member 20 is interposed. The workpiece 200 is pressed against the base member 18. In addition, since the sheet material 22 is provided on the base member 18, the workpiece 200 includes the pressing member 20 and the base member 18 through the resin members 52-2b and 52-2c and the sheet material 22. It will be in the state clamped by. Thereby, the workpiece 200 can be prevented from being damaged by the pressing member 20 and the base member 18.

  At this time, when the workpiece 200 has a conical shape, for example, the pressing plate 52 of the pressing member 20 rotates in the arrow A direction or the arrow B direction according to the shape of the workpiece 200. Thus, the workpiece 200 can be pressed against the base member 18 by the resin members 52-2b and 52-2c. As a result, the workpiece 200 having a conical shape can be more reliably fixed as compared with the fixing jig 120 according to the conventional technique.

  Further, when the workpiece 200 is large in the vertical direction, the number of metal plates 18-1, 18-2, 18-3 constituting the base member 18 according to the vertical size of the workpiece 200 is determined. To reduce.

  That is, according to the size of the workpiece 200 in the vertical direction, the base member 18 is made of two layers of the metal plates 18-2 and 18-3 or one layer of the metal plate 18-3, and the thickness of the base member 18 is changed. adjust.

And the sheet | seat material 22 is mounted on the upper surface of the adjusted base member 18, and the to-be-processed object 200 is mounted in the base member 18 via the sheet | seat material 22, At this time, the metal plate 18-1 is mounted. , 18-2 and 18-3 have the same configuration, and grooves similar to those of the metal plate 18-1 are formed on the upper surfaces of the metal plates 18-2 and 18-3. The 200 placement positions can be easily determined.

  Further, when the workpiece 200 has a cylindrical shape, the sheet material 22 is removed and the groove 18-1e (or the groove 18) formed in the metal plate 18-1 (or the metal plates 18-2, 18-3). -2e, 18-3e), the workpiece 200 can be stably held between the pressing member 20 and the base member 18 by placing the workpiece 200 on the fixing jig 10 reliably. It can be fixed by.

  In this way, in the workpiece 200 held between the pressing member 20 and the base member 18, an image on the processing surface of the workpiece 200 is formed at the position where the light from the optical sensor 150 is projected. The moving mechanism 14 moves on the XY plane so as to be positioned in the vicinity of the center position of the marking area, and is fixed by the fixing member 34 at a predetermined position.

  Thereafter, fine adjustment in the X-axis direction and the Y-axis direction is performed by the X-axis direction adjustment screw 42 and the Y-axis direction adjustment screw 40 based on the position where the light from the optical sensor 150 is projected, and the workpiece 200 is The light from the optical sensor 150 is projected onto the center position of the embossed area where the image is formed on the processed surface.

  In the workpiece 200 fixed by the fixing jig 10 in this way, for example, when the workpiece 200 is long in the X-axis direction and forms stamped images at two locations, 1 By positioning the second part in the opening 52-2a and positioning the second part in the region protruding from the slide member 16 on the base member 18, the position adjustment by the fixing jig 10 is not performed. Image formation can be performed only by moving the marking head 118 of the engraving machine 100.

  In this way, after the workpiece 200 is securely fixed to the fixing jig 10, the stamping machine 100 is operated by a predetermined process to form a desired image on the workpiece 200.

Thereby, in the stamping machine 100, by fixing the workpiece 200 using the fixing jig 10, compared with the case of fixing the workpiece 200 using the fixing jig 120, it is more possible. Stamped images can be formed on workpieces of many types of shapes.
