JP 2004-223638 A Japanese Patent Application Laid-Open No. 11-309656

In the prior art described in the above-mentioned Patent Document 1, since the tool part of the deburring tool is moved along the peripheral part while contacting the peripheral part of the hole, the movement of the deburring tool is not a straight line but a circular route. It takes time to draw and move, and productivity is not good.
Further, a mechanism for rotating the guide, a mechanism for sliding the guide, and a mechanism for rotating the tool portion are necessary, and the apparatus is complicated.
Furthermore, if there are many holes for removing burrs in the workpiece, the apparatus for moving the tool portion to each hole becomes more complicated and the productivity is further deteriorated.
In the deburring method described in Patent Document 2, when the burr in the hole is removed with the polishing brush, the followability of the polishing brush in contact with the work is poor, and particularly when the polishing brush enters the hole, the peripheral portion of the hole is The tendency to enter after passing is remarkable, and it is difficult to reliably deburr the peripheral edge of the hole.
Further, since the polishing brush bends when the polishing brush is brought into contact with the vicinity of the hole of the work, unnecessary scratches may be made on the surface around the hole. In particular, the larger the hole diameter, the stronger the polishing brush needs to be brought into contact with each other, so that it is easy to be damaged, and the deformation of the polishing brush increases and the brush life is shortened.
The present invention has been made in order to solve such problems, and efficiently and surely removes burrs at the peripheral edge of a hole formed in the workpiece and does not cause unnecessary damage to the workpiece. An object is to provide a deburring method and a deburring apparatus.

  The invention of claim 1 is a method of removing a burr at a peripheral edge of a hole having a circular cross section formed through a workpiece with a disc-shaped deburring device having a polishing portion on an outer edge portion, which rotates. The workpiece with the hole is fixed, the rotation axis of the deburring device is inclined by a predetermined angle with respect to the axis of the hole of the workpiece, and the workpiece is applied to the workpiece from the axial direction of the hole while rotating the deburring device. In a direction crossing the hole from the one end of the peripheral edge of the hole through the center of the hole while being pressed in the axial direction of the hole and symmetric with respect to the center of the hole with respect to the one end The deburring method is characterized by removing the burr in the hole by moving in the radial direction to the end portion.

  According to the first aspect of the present invention, the disc-shaped deburring device having the polishing portion at the outer edge rotates around the rotation axis inclined at a predetermined angle with respect to the axis of the hole formed through the workpiece. The outer edge of the hole is brought into contact with the peripheral edge of the hole while moving in the horizontal direction (the radial direction of the hole) while being pressed in the vertical direction. Therefore, the outer edge portion of the deburring device can contact the peripheral edge of the hole sequentially, and the burrs on the peripheral edge of the hole can be reliably removed by the shortest distance movement. Further, since the outer edge of the deburring device is hardly in contact with any part other than the peripheral part of the hole, there is no possibility of causing unnecessary scratches in parts other than the hole of the workpiece.

  According to a second aspect of the present invention, in the first aspect of the invention, when there are a plurality of through holes formed in the workpiece and each hole is on the same plane, the burr at the peripheral portion of each hole is removed. The workpiece is rotated with the center of a plurality of concentric circles passing through the center of each hole as a rotation axis, and the rotation of the deburring device with respect to the axis of the hole of the workpiece is sequentially rotated with respect to each hole. Center the hole from one end of the peripheral edge of the hole while inclining the shaft at a predetermined angle, abutting the workpiece from the axial direction of the hole while rotating the deburring device, and pressing in the axial direction of the hole A deburring method for removing burrs in each hole by moving in a radial direction to an end portion that is symmetric with respect to the center of the hole with respect to the one end portion in a direction crossing the hole through the hole It is.

  According to the second aspect of the present invention, when there are a plurality of holes formed in the workpiece, the workpiece is rotated based on the centers of a plurality of concentric circles passing through the centers of the plurality of holes to perform deburring. Deburring the holes along the horizontal movement line of the deburring device and deburring each hole in sequence, so it is not necessary to move the deburring device in a complex manner on the horizontal plane simply by rotating around one point of the workpiece. However, deburring can be reliably and efficiently performed for a plurality of holes.

  According to a third aspect of the present invention, in the first and second aspects of the invention, the radial movement of the outer edge portion of the deburring device that is in contact with the hole peripheral portion is determined from the outermost peripheral position of the hole peripheral portion in the radial direction. The deburring method is characterized in that it moves to the inner peripheral position or from the innermost peripheral position of the hole peripheral part to the outermost peripheral position of the hole peripheral part to remove burrs from the hole.

According to the invention of claim 3, the movement of the deburring device in the horizontal plane is as shown in FIG. 3 from the hole peripheral part outermost peripheral position Po in the radial direction to the hole peripheral part innermost peripheral position Pi, or the hole peripheral part. It is performed linearly from the innermost peripheral position Pi of the hole to the outermost peripheral position Po of the hole periphery. Therefore, despite the deburring of the peripheral edge He of the circular hole, the movement distance of the deburring device can be minimized and the deburring can be performed efficiently.
In the present invention, with respect to the peripheral portion of the target hole, the position of the peripheral portion farthest from the rotation center of the workpiece is the outermost peripheral position of the peripheral portion of the hole, and the position of the peripheral portion closest to the rotational center is the innermost peripheral portion of the hole peripheral portion. The position is defined (see FIG. 2).

  According to a fourth aspect of the present invention, in the configuration of the second aspect of the invention, the rotation axis is predetermined with respect to the axis of the hole of the workpiece while rotating the workpiece around the center of a concentric circle passing through the center of each hole. The deburring device that rotates at an angle is brought into contact with the workpiece from the axial direction of the hole and moved in the radial direction of the hole to continuously remove burrs in the holes. It is a taking method.

  According to the fourth aspect of the present invention, the deburring device is continuously brought into contact with the plurality of holes formed in the workpiece only by bringing the deburring device into contact with the workpiece and moving in the radial direction within the horizontal plane while the workpiece is rotated. In addition, since the burrs can be removed, it is very efficient, and the apparatus can be realized with a simple mechanism.

Can be inclined at a predetermined angle and can be moved in the radial direction of the hole while pressing in the axial direction of the hole, so that the corner portion of the outer edge portion of the deburring device is along the peripheral edge of the hole. Can move to remove burrs. At this time, the outer edge portion of the deburring device hardly touches the surface of the workpiece other than the hole, so that unnecessary damage is not caused on the surface around the hole.

  According to the invention of claim 6, the third drive unit for moving the deburring device (or the jig for fixing the workpiece) in the radial direction of the hole can arbitrarily set the position to move and stop, so it is formed on the workpiece. The plurality of holes can also be set to move and stop at the outermost peripheral edge position and the innermost peripheral edge position of each hole. Therefore, the deburring device can be moved in the minimum necessary by sequentially pressing and radially moving only the hole to be deburred, and the work surface is not damaged unnecessarily.

  The invention of claim 7 is the deburring device according to claims 5 and 6, wherein when the deburring device is in contact with and pressed against the workpiece, the outer edge portion of the deburring device is bent along the workpiece, It is characterized by forming a curved surface.

  When the deburring device according to the invention of claim 7 is used, the outer edge portion of the deburring device is bent to form a curved surface when pressed against the workpiece, so that the deburring device enters the hole more reliably and sequentially reaches the peripheral edge of the hole. The burr can be surely removed by contact. Furthermore, since the deburring device is bent in contact with the workpiece, the deburring device is prevented from being pressed more strongly than necessary and the surface other than the hole of the workpiece is prevented from being damaged.

As described above, according to the first to ninth aspects of the present invention, the disk-shaped deburring device rotating around the axis is pressed in the axial direction of the hole, and linearly in the radial direction of the hole. Since it is configured to move, burrs at the peripheral edge of the hole can be removed efficiently and reliably.
Also, when there are multiple holes in the workpiece, the workpiece can be rotated to bring each hole sequentially on the movement line on the horizontal plane of the deburring equipment, so that the peripheral edge of each hole can be deburred sequentially. Deburring of a plurality of holes can be performed efficiently and reliably with a simple movement of the deburring device, and unnecessary scratches on the workpiece surface can be minimized.
Here, the burrs can be removed more efficiently by moving the deburring device while rotating the workpiece.

The first driving unit 3 is configured to rotate the jig 2 about the axis c1 as a rotation axis by a motor, and the rotation of the motor is controlled by a control unit (not shown). Therefore, the jig 2 is rotated by inputting a predetermined value in the control unit, and the hole to be deburred can be set to be on the movement line in the horizontal plane of the deburring device 4.

The third drive motor 60 is fixed to the base, and the slide portion 61 is set to be slidable on the base 8 in the X direction. The horizontal drive arm 64 connects the third drive motor 60 and the slide portion 61, converts the rotational force of the third drive motor 60 into a horizontal force, and moves the slide portion 61 on the base in the radial direction (X Direction). The support column 62 is fixed to the slide portion 61, and the support arm 63 is fixed to the support column 62.

A lifting arm 72 is fixed to the lifting part 71.

With the above configuration, the third drive unit 6 and the fourth drive unit 7 are perpendicular to the radial direction (X direction) of the hole so that the outer edge portion of the deburring device 4 is in contact with the peripheral portion of the hole to be deburred. The deburring device 4 is moved in the (Z direction).
The second drive unit 5, the third drive unit 6, and the fourth drive unit 7 are also controlled by a control unit (not shown) in the same manner as the first drive unit 3.

Next, the deburring operation by the deburring device of this embodiment will be described with reference to FIGS. FIG. 2 is a side view of the workpiece 1, the deburring device 4, the jig 2, and the second drive unit 5 shown in FIG.
First, as shown in FIGS. 1 and 2, the work 1 in which a hole to be deburred is formed is positioned and fixed to the jig 2. Next, the motor of the first drive unit 3 is driven to rotate the workpiece 1 together with the jig 2, and the hole h1 to be deburred is moved along the movement line in the horizontal plane of the deburring device 4 (line segment L- in FIG. 2). L)) and stop. The direction of the line segment LL coincides with the X direction.
Next, if the motor of the third drive unit 6 is driven to move the slide unit 61 on the base 8, the slide unit 61 moves in the X direction, so the third drive unit via the fourth drive unit 7. The second drive unit 5 attached to 6 also moves in the X direction, and the deburring device 4 supported by the second drive unit 5 also moves in the X direction.
Here, by simultaneously moving the elevating part 71 upward (Z direction) by the drive motor of the fourth drive part 7, the corner 41c (see FIG. 3) of the outer edge part 41 of the deburring device 4 is changed to the peripheral edge He of the hole h1. The hole h1 can be deburred by moving from the outermost peripheral position Po to the innermost peripheral position Pi (or from the innermost peripheral position Pi to the outermost peripheral position Po).

FIGS. 3 and 4 illustrate the state of contact between the deburring device 4 and the hole peripheral edge He at this time. First, while rotating the deburring device 4 around the axis C2, the corner 41c of the outer edge portion 41 as the polishing portion is brought into contact with the outermost peripheral position P1 (Po) of the hole peripheral portion. In this state, the third drive unit 6 moves in the radial direction (X direction) while pressing in the Z direction by the fourth drive unit 7. As a result, the locus of the tip of the outer edge portion 41 of the rotating deburring device 4 reaches a hole peripheral edge innermost peripheral position P3 (Pi) through a parabolic route as P1 → P2 → P3. In this process, the corner 41c of the outer edge portion 41 of the deburring device 4 is formed in the hole h1 between the route P1 → S1 → P3 and the route P1 → S2 → P3 of the peripheral edge He of the hole h1, as shown in FIG. Since it moves in contact with all the lower parts of the peripheral edge He, all burrs B on the peripheral edge He of the hole h1 are removed.
At this time, the outer edge portion 41 of the deburring device 4 is not in contact with any part other than the peripheral edge portion of the hole h1, so that no unnecessary damage is caused on the surface of the workpiece.

Deburring is performed by bringing the outer edge 41 of the deburring device 4 into contact with the outermost peripheral position P1 (Po) of the peripheral edge He of the hole h1 and moving it to the innermost peripheral position P3 (Pi).

It comes on the line (on line LL in FIG. 2) and stops, and deburring is performed in the same manner as the hole h1 described above. When the deburring of the hole h2 is completed, the same operations as those of the hole h3 and the hole h4 can be sequentially repeated to easily deburr all the holes of the work 1.
In FIG. 2, the holes h <b> 1 to h <b> 4 have a shape that is equidistant from the rotation center of the workpiece 1 and has the same hole diameter. It is possible to deal with holes.

  As a method other than the above, it is also possible to move the deburring device while rotating the workpiece and remove the burrs continuously from the plurality of holes.

  The shape of the outer edge portion 41 of the deburring device 4 is not limited to a cross-sectional shape having a right angle as shown in FIG. 5A, but is shown in FIGS. 5B and 5C. As described above, a rounded corner portion, a semicircular shape, or an elliptical shape can be used.

  In the first embodiment shown in FIG. 1, the fourth drive unit 7 that moves in the vertical direction is provided in the third drive unit 6 that moves in the horizontal direction, but the reverse configuration (fourth drive). The third drive unit 6 may be provided on the unit 7).
