BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chamfering machine for chamfering a work material such as a plate material or a square material placed on a table.

[0002]

2. Description of the Related Art As a conventional technique, a frame is provided with a support plate orthogonal to the surface of a table, and a holder is attached to the support plate so as to be rotationally adjustable about an X axis (horizontal axis). A motor that rotates around an axis (a longitudinal axis) is attached, a chamfering cutter is attached to the rotating shaft of the motor, and the holder is rotated about the X axis so that the rotation axis of the chamfering cutter is on the surface of the table. On the other hand, there were those that were changed in a parallel or orthogonal direction.

[0003]

In the above-mentioned prior art, since the chamfered cutter can be chamfered with the chamfering cutter oriented horizontally or vertically with respect to the table, the chamfering of the machined material in which the portion to be machined is parallel to the table and the guide. Can be done smoothly.
However, in the above-mentioned conventional one, the holder supporting the chamfering cutter is integrally fixed to the frame through the support plate, so that the chamfering depth changes when the work material is warped or the wall thickness is changed. There was a drawback to An object of the present invention is to obtain a new chamfering machine that solves the above-mentioned drawbacks.

[0004]

The present invention is configured as follows to achieve the above object. That is, a support plate is provided on the frame so as to be rotatable about the X axis, and a pair of plate springs whose surfaces are parallel to the surface of the table and are vertically spaced apart from each other are provided, and one end of the plate spring is fixed to the support plate. , A bracket perpendicular to the surface of the table is fixed to the other end of each leaf spring by projecting downward, and a holder is provided below the bracket so that the holder can be rotated and adjusted about the X axis, and the holder is centered on the Y axis. As a result, a motor that rotates is provided, and a chamfering cutter and a copying roller are provided on the base portion and the outer end portion of the rotation shaft of the motor.

[0005]

Since the present invention has the above-mentioned structure, when the support plate is rotated in units of 90 degrees about the X-axis, the plane of the leaf spring changes parallel or orthogonal to the plane of the table, When the holder is rotated about the X axis in 90 degree units, the rotation axis of the motor changes in a direction parallel or orthogonal to the surface of the table. In this case, when the rotation axis of the motor is parallel to the surface of the table in a state where the surface of the leaf spring is parallel to the surface of the table, the motor and hence the chamfering cutter and the copying roller are connected via the leaf spring. It becomes possible to move in a direction perpendicular to the table, the copying roller rolls along the upper surface or the lower surface of the processed material, and the chamfering cutter chamfers the processed material by performing the upper surface copying or the lower surface copying. When the plane of the leaf spring is orthogonal to the plane of the table and the rotation axis of the motor is orthogonal to the plane of the table, the motor, and hence the chamfering cutter and the copying roller, are attached to the table through the leaf spring. On the other hand, it becomes possible to move in a parallel (horizontal) direction, the copying roller rolls along the side surface of the processed material, and the chamfering cutter chamfers the processed material by side surface copying.

First, a case will be described in which the copying roller 23 rolls along the upper surface of the processed material W and the chamfering cutter 22 chamfers the processed material W by the upper surface copying. The horizontal rod 7 is attached to the four screw holes 10b, 10c, 10e, and 10f on the right side of the support plate 10.
As shown in FIGS. 1 to 3, the bolts 7a to 7d provided on the table 1 are screwed to arrange the surfaces of the leaf springs 11 and 12 in parallel with the surface of the table 1. Next, the holder 15 is rotated about the X-axis (a), that is, the X-axis bolt 16 so that the rotary shaft 21 of the motor 20 is parallel to the table 1 (Y-axis direction), and then the X-axis bolt 16 is tightened. To fix the holder 15 to the bracket 14. Then, the Z-axis screw 4, the Y-axis screw 6 and the right adjusting screw 27 are operated so that the lower end of the copying roller 23 is located slightly below the upper surface of the right end of the workpiece W placed on the table 1.

In this state, the motor 20 is started, the chamfering cutter 22 is rotated in a predetermined direction, and the processed material W is moved along the guide 28 installed on the table 1 in the X-axis direction,
That is, the chamfering cutter 22 is moved in the direction. Then, the copying roller 23 rolls along the upper surface of the right end of the processed material W, and the chamfering cutter 22 cuts and chamfers the right upper edge of the processed material. In this case, the leaf springs 11 and 12 are parallel to the surface of the table 1, and the support plate 10 and the connecting plate 13 are perpendicular to the surface of the table 1, that is, the leaf springs 11 and 12 are the same. Since the support plate 10 and the connecting plate 13 are parallelograms, when the upper surface of the processed material W changes in the vertical direction, the leaf springs 11 and 12 are elastically deformed and the motor 20 and thus the chamfering cutter 22. Is the above processed material W
The chamfering cutter 22 chamfers the workpiece W along the upper surface by vertically moving along the upper surface of the chamfering cutter 22.

Next, a case where the copying roller 23 rolls along the side surface of the processed material W and the chamfering cutter 22 chamfers the processed material W by side surface copying will be described. The support plate 10 is rotated 90 degrees clockwise from the state of FIG. 3 around the bolt 10e provided on the horizontal rod 7, that is, the X-axis (a), and the bolts 7a to 7d provided on the horizontal rod 7 are attached to the support plate 10. 4 on the left

As shown in FIG. 4, the surface of each leaf spring 11 and 12 is attached to the table 1
Place it perpendicular to the plane of. Next, the holder 15 is rotated 90 degrees counterclockwise from the state of FIG. 3 around the X-axis bolt 16, that is, the X-axis line (a), and then the X-axis bolt 16 is tightened to be fixed to the bracket 14. As shown in FIG. 4, the rotation axis center of the motor 20, that is, the rotation axis 21 is oriented perpendicularly to the table 1. Then, the Z-axis screw 4 and the Y-axis screw 6 are operated so that the left end of the copying roller 23 is located slightly left of the upper portion of the right side surface of the processed material W placed on the table 1.

In this state, the motor 20 is started, the chamfering cutter 22 is rotated in a predetermined direction, and the processed material W is moved along the guide 28 in the X-axis direction, that is, the chamfering cutter 22 direction. Then, the copying roller 23 rolls along the upper portion of the right side surface of the processed material W, and the chamfering cutter 22
Cuts and chamfers the right upper edge of the processed material. In this case, since the leaf springs 11 and 12 are perpendicular to the surface of the table 1, the leaf springs 11 and 12 are elastically deformed when the right side surface of the processed material W changes in the left-right (Y-axis) direction. Then, the motor 20 and thus the chamfering cutter 22 moves left and right along the right side surface of the processed material W, and the chamfered cutter 22 chamfers the processed material W by copying the side surface.

[0015]

As is apparent from the above description, according to the present invention, the holder is attached to the swing side ends of the pair of leaf springs whose surfaces are rotated in the direction parallel or orthogonal to the surface of the table.
Since the holder is provided with a motor that rotates about the Y axis, and a chamfering cutter and a copying roller are provided on the base and the outer end of the rotation axis of the motor, The structure is simplified, and the chamfering of the processed material can be performed either by the vertical chamfering or the side chamfering, and the chamfering with a uniform depth can be achieved even if the machined material is warped or the wall thickness varies.
