  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a schematic configuration of a deburring device according to an embodiment.

  In the figure, a is a chuck mechanism, b is a buff mechanism, and the chuck mechanism a will be described below.

  The chuck mechanism a is provided so as to hang down from the top plate 3 provided on the upper part of the support columns 2, 2. That is, the chuck mechanism a is suspended from the drive rod 4 a of the cylinder 4 driven by hydraulic pressure or pneumatic pressure provided on the top plate 3, and is provided between the base 1 and the top plate 3. The guide piece 5 is configured to be guided.

  Therefore, when the cylinder 4 is driven, the chuck mechanism a can move so as to approach the buff mechanism b provided on the base 1 and move away from the buff mechanism b. (See arrow (1) in FIG. 1). That is, as will be described later, the chuck mechanism a can advance the deburring side of the workpiece W gripped by the chuck mechanism a toward the buffing mechanism b side, and also the deburring side of the workpiece W. Can be moved backward from the buff mechanism b side.

  The chuck portion 6 is provided at the lower portion of the chuck mechanism a, and the workpiece W is moved to three claws 6a, 6a, 6a (2 in FIG. 1) similarly to the chuck portion provided in a known machine tool such as a lathe. Only the claw of the book is shown) so that it can be detachably gripped (see arrow (2) in FIG. 1). The claws 6a, 6a, 6a are configured to be actuated by a hydraulic or pneumatic cylinder mechanism, similar to an automated chuck part of a machine tool (not shown).

  The motor 7 composed of a reversible motor is provided on the frame a ′ of the chuck mechanism a, and the sprocket 7b provided on the rotating shaft 7a is chained to the sprocket 6b provided on the rotating shaft 6a of the chuck portion 6. 8 are connected.

  Accordingly, the chuck portion 6 can be rotated in the forward direction by rotation of the motor 7 in one direction (hereinafter referred to as forward rotation), and the chuck portion 6 can be rotated in the other direction of the motor 7 (hereinafter referred to as reverse rotation). Can be reversely rotated (see arrows (3) and (4) in FIG. 1).

  A workpiece W (a vehicle wheel made of an aluminum alloy in the example shown in the figure) W gripped by the chuck mechanism a is transported to the deburring device according to the present invention by the transport mechanism c, and further to another place after deburring. It is configured to be conveyed.

  Of the transport mechanism c, the transport section c ′ positioned below the chuck mechanism a is provided with a relief mechanism so that the transport mechanism c does not get in the way when the workpiece W is deburred.

  That is, as shown in FIG. 2, the conveyance section c 'below the chuck mechanism a is composed of roller conveyors 9a and 9b separated on both the left and right sides, and the roller conveyors 9a and 9b are end portions opposite to each other. Is configured to be rotatable, and is configured to be able to rotate 90 ° downward by a hydraulic or pneumatic cylinder (not shown) (see arrows A and B in FIG. 2).

  Therefore, when the roller conveyors 9a and 9b are rotated to the position indicated by the two-dot chain line in FIG. 2 while the workpiece W is gripped by the chuck mechanism b, the chuck mechanism b contacts the workpiece W with the conveyance unit c ′. It is possible to move downward without making it.

  Each of the roller conveyors 9a and 9b is configured in a power mora type that can rotate by itself, and when the roller conveyors 9a and 9b are positioned at the solid line positions in FIG. It is comprised so that it can be made to convey.

  The buffing mechanism b rotatably supports a buffing wheel 11 as an example of a polishing member made of a group of wires planted on a rotating shaft 10a of a reversible motor 10 and a casing 10b of the motor 10, and a base 10b. A base 12 that is movable with respect to the base 1 is provided. The wire constituting the buff wheel 11 is determined by the material of the workpiece W, but a steel wire is used when the workpiece W is an aluminum alloy vehicle wheel. In addition, the shape of the polishing surface formed at the tip of the wire group constituting the buff wheel 11 matches the shape when the deburring surface of the workpiece W is cut, that is, the shape of the polishing surface of the wire group is the workpiece W. Are formed along the shape of the deburring surface (see FIGS. 4 and 5 described later). Furthermore, although the size of the buffing wheel 11 is determined by the size of the workpiece W, it is desirable to make it smaller than the deburring surface of the workpiece W.

  The buffing wheel 11 is supported so as to be rotatable about the mounting shaft 12a of the gantry 12 of the casing 10b, that is, the polishing surface is rotatable so as to be movable relative to the deburring surface of the workpiece W. (See arrow (5) in FIG. 1). Further, when the buffing wheel 11 is not in contact with the workpiece W by the compression spring 13, the axial center direction of the rotating shaft 10a of the buffing wheel 11 is orthogonal to the lower surface which is the deburring surface of the workpiece W in FIG. It is urged so as to maintain a crossing position at an angle other than the angle of 45 degrees, for example. Therefore, when the buffing wheel 11 is pushed down by the work W to be lowered, that is, when the polished surface of the wire group is pressed on the deburring side of the work W, it can move against the spring 13. It has become.

  The rotating shaft 10a of the buffing wheel 11 has all the burrs B provided on the lower surface thereof as shown in FIG. The lines B1 to B4 are configured to intersect at a predetermined angle. That is, FIG. 3A is a view of the work W as viewed from below, and shows the relationship between the burr B formed around the recess W ′ provided on the lower surface of the work W and the buffing wheel 11. Yes. Then, it is determined so as to have a predetermined angle θ, for example, 5 °, with respect to the lines B3 and B4 of the upper and lower burrs B. If the buffing wheel 11 is arranged in such a relationship with respect to the lines B1 to B4 of the burr B, it is possible to deburr all the lines B1 to B4.

  If the inclination of the buff wheel 11 can be reversed as shown in FIG. 3B in addition to the inclination (θ) described above, the burrs at the square portions of the recesses W ′ are more completely removed. can do. Therefore, when changing to such a reverse inclination, the gantry 12 is equipped with an inclination changing mechanism comprising a hydraulic cylinder or the like.

  The gantry 12 is configured to be able to move on a rail 1 a provided on the base 1 against the spring 14 by the force of pressing and pressing when the buffing wheel 11 is pressed by the work W.

  In FIG. 1, S1 and S2 are limit switches, which are configured to detect the position when the buff wheel 11 is pressed by the work W and turned. That is, the limit switches S1 and S2 can be operated when the operation element 12b fixed to the mounting shaft 12a of the casing 10b of the motor 10 rotates in conjunction with the rotation of the buff wheel 11. ing.

  In addition to the limit switches S1 and S2, the position detection sensor of the chuck mechanism a, the position detection sensors of the claws 6a, 6a, and 6a of the chuck unit 6, that is, the sensor that detects the gripping state of the chuck unit 6, and the conveyance Various sensors such as a sensor for detecting the conveyance position of the mechanism c, that is, a sensor for detecting the workpiece W of the conveyance section c ′ below the chuck mechanism a are provided, but are omitted here. The detection signals of the limit switches S1 and S2 and the detection signals of the sensors are input to a sequence controller (not shown) that controls the deburring device in an integrated manner.

  Hereinafter, the deburring operation of the workpiece W will be described with reference to FIGS. 4 and 5 as well.

  Assuming that the workpiece W has been conveyed below the chuck mechanism a by the conveyance mechanism c, the chuck mechanism a has the cylinder 4 up to the upper position of the workpiece W with the claws 6a, 6a, 6a of the chuck portion 6 opened. Is lowered by. Next, the claws 6a, 6a, 6a are closed and the workpiece W is gripped.

  When the workpiece W is gripped by the chuck mechanism a, the roller conveyors 9a and 9b of the transport section c ′ below the chuck mechanism a are opened as shown by the two-dot chain line in FIG. When the conveyance unit c ′ is opened, the chuck unit 6 is rotated forward by the motor 7 and the lowering of the chuck mechanism a is started by the cylinder 4. Further, the motor 10 starts normal rotation of the buff wheel 11. Here, in the normal rotation of the chuck portion 6 and the buffing wheel 11 here, the rotation direction of the workpiece W and the rotation direction of the buffing wheel 11 are maintained in an opposite relationship as indicated by arrows in the drawing.

  When the workpiece W descends while rotating in the forward direction due to the rotation of the chuck portion 6, the deburring surface of the workpiece W comes into contact with the buffing wheel 11 that is rotating in the forward direction, and the limit switch S1 is activated (ON) by the operator 12b. It is detected that the taking has started (see FIG. 4A).

  When the lowering of the chuck mechanism a further proceeds and the rotation of the buff wheel 11 stops, the movement of the gantry 12 is started. In this way, the movement of the buffing surface, that is, the deburring position is effectively performed, and the portions that need to be deburred can contact the buffing wheel 11 evenly (see FIG. 4B).

  When the lowering of the chuck mechanism a further proceeds and the operation element 12b operates (ON) the limit switch S2 (see FIG. 4C), the lowering of the chuck mechanism a is stopped, and the chuck portion 6 and the buffing wheel 11 are stopped. The forward rotation of is temporarily stopped. Thereafter, normal rotation of the chuck portion 6 and the buffing wheel 11 is resumed, and then the raising of the chuck mechanism a is started by the cylinder 4 (see FIG. 5A). During this ascent, burrs that could not be removed when descending are effectively removed together with the movement of the gantry 12 to the opposite side, which will be described later.

  As the chuck mechanism a rises, the angle of the rotating shaft 10a of the buff wheel 11 gradually approaches the original angle, and the gantry 12 is also moved so as to gradually approach the original position (FIG. 5B). reference).

  When the raising of the chuck mechanism a further proceeds and the operation element 12b operates (turns off) the limit switch S1 again (see FIG. 5 (c)), the rotation of the chuck 6 and the buff wheel 11 is stopped.

  Next, the chuck portion 6 and the buff wheel 11 are reversed, and the above-described operation is repeated. Then, when the workpiece W rises above the conveyance surface of the conveyance mechanism c, the driving of the cylinder 4 is also stopped.

  When the workpiece W rises above the conveyance surface of the conveyance mechanism c, the roller conveyors 9a and 9b of the conveyance unit c ′ return to the original state (see the solid line position in FIG. 2), and then the claw 6a of the chuck unit 6 , 6a, 6a are opened, and the gripping state of the chuck mechanism b is released.

  The workpiece W released from the chuck mechanism b is moved to the next step by the transport mechanism c, and dust is removed from the workpiece W by the compressed air.

  With the above configuration, since the workpiece W can be automatically deburred, the cost of deburring can be reduced and the burden on the worker can be greatly reduced.

  In the above example, the vertical movement of the chuck mechanism a is reciprocated twice, but this may be one reciprocation. In this case, the rotation direction of the chuck portion 6 and the buffing wheel 11 is changed between when descending and when ascending. However, the deburring effect can be enhanced when the vertical movement is two reciprocations as described above. Further, although the chuck mechanism a is lowered and raised, the buff mechanism a may be raised and lowered.
