[Work support mechanism and deburring device]
The section cut product (1) in Fig. 1 is a plate-shaped projection (3) standing near the side edge of a square plate (2), and is manufactured by cutting an aluminum extrusion to the required length. It is a thing. The front side surface (4a) and the opposite side surface (4b) in the drawing are cut surfaces. The deburring device according to the present embodiment employs the work support mechanism according to the present invention, and can be suitably used for deburring the cut surfaces (4a) and (4b) of the section cut product (1).

  FIG. 2A is a plan view schematically showing the deburring device (10), and FIG. 2B is a side view. FIG. 2C is a front view of the work support part (20) in the deburring device (10).

  The deburring device (10) includes a workpiece support (20) and a reference plate (12) that are set apart on the machining table (11), and a deburring brush (13 that is set above the machining table (11)). ).

  In the work support part (20), the rotary table (22) is mounted on the side surface of the base (21) so as to stand up on the machining table (11). The rotary table (22) A positioning plate (23) and supporting auxiliary members (30), (31) are attached to the rotary table (22) so as to rotate coaxially. (Q) is a rotating shaft of the rotary table (22), the positioning plate (23), and the supporting auxiliary members (30) and (31).

  In the following description, the direction including the rotation axis (Q) in the plane parallel to the machining table (11) is the X axis, and the direction orthogonal to the X axis is orthogonal to the Y axis, X axis, and Y axis in the same plane. The direction to do is the Z axis. Further, in the X-axis direction, the direction of the reference plate (12) is “front” and the “back” of the workpiece support (20). Further, the position in the circumferential direction around the rotation axis (Q) is represented by an angle, the position directly above is 0 °, and the position directly below is 180 °.

  The positioning plate (23) is a rectangular flat plate for positioning the workpiece in contact with the X axis, and is parallel to the table surface via four legs (24) on the rotary table (22). It is fixed to. Two side guides (25) are attached to one opposing side end of the positioning plate (23) so as to protrude forward from the positioning plate (23). These side guides (25) are used to position the workpiece in the Y-axis direction, and the distance between the opposing side guides (25) and (25) corresponds to the width of the plate (2) of the sectioned product (1). is doing. In addition, in FIG. 2B, illustration of the said leg (24) is abbreviate | omitted for convenience of description of the following support auxiliary member (30) (31).

  In addition, a circular hole (26) is formed in the center of the positioning plate (23), and the suction holding part (28) at the tip of the shaft part (27) of the suction device is disposed in the circular hole (26). Yes. The shaft part (27) of the suction device rotates coaxially with the rotary table (22), and the back surface of the plate (2) of the section cut product (1) is placed on the front surface (23a) of the positioning plate (23). When the suction device is operated with contact, the plate (2) is sucked by the suction holding portion (28), and the cut shape product (1) is held by the suction holding portion (28). The held section cut product (1) rotates with the rotation of the rotary table (22) and is supported at a required angle.

  The supporting auxiliary member (30) (31) is a flat plate arranged outside the other opposing end of the positioning plate (23), and is installed between the rotary table (22) and the positioning plate (23). It is attached to the rotary table (22) via the spring-loaded shaft (32). A slider (33) that moves on the shaft (32) along with expansion and contraction of the spring is mounted on the shaft (32), and a rear end portion of the support auxiliary member (30) (31) is fixed to the slider (33). Thus, the support auxiliary members (30) and (31) move in the X-axis direction together with the slider (33). Normally, the slider (33) is pushed rearward by the restoring force of the spring of the shaft (32) and comes into contact with the rotary table (22), and the front ends of the support auxiliary members (30) and (31) are located on the positioning plate (23 ), That is, hidden behind the suction holding part (28) and hidden, the support auxiliary members (30) and (31) are moved forward of the positioning plate (23) when the slider (33) advances. 23a), that is, it protrudes from the suction holding portion (28). The amount of protrusion from the positioning plate (23) follows the amount of movement of the slider (33). In FIG. 2B, the supporting auxiliary member (31) located at 0 ° is recessed from the positioning plate (23), and the supporting auxiliary member (30) located at 180 ° is projected from the positioning plate (23).

  Further, a bearing (34) having a vertical line as a rotation axis is attached to the outer surface of each support auxiliary member (30) (31).

  A bearing guide block (35) is fixed below the positioning plate (23) of the workpiece support (20). As shown in FIGS. 2B, 2C, and 3, the bearing guide block (35) is a trapezoidal column, and the pair of parallel side surfaces (36a) and (36b) are arranged on the X axis so as to be parallel to the Y axis. The long side surface (36a) faces backward, the short side surface (36b) faces forward, and the two inclined side surfaces (36c) face each other on the Y axis. Further, the position of the long side surface (36a) on the X axis coincides with the rear end position on the outer peripheral surface of the bearing (34) of the supporting auxiliary members (30) and (31) at the immersion position.

  Then, the protrusions and depressions of the support auxiliary members (30) and (31) are controlled as follows by contact between the bearing (34) and the guide block (35) (see FIG. 3).

  When the support auxiliary member (30) (31) rotates with the rotation of the turntable (22) and approaches a position of 180 °, the bearing (34) is the length of the inclined side surface (36c) of the bearing guide block (35). It contacts the side (36a) side edge of the side, and the bearing (34) is rotated by contact with the inclined side (36c) while moving on the inclined side (36c) in the direction of the short side (36b). Go. During this time, the supporting auxiliary members (30) and (31) move forward while increasing the protruding amount from the auxiliary supporting plate (23), and the protruding amount becomes maximum when reaching the side surface (36b) on the short side. The slider (33) fixed to the support auxiliary member (30) (31) also advances, and the spring of the shaft (32) contracts against the elastic force by the advance of the slider (33), and the slider is restored by the restoring force. The bearing (34) is pressed against the bearing guide block (35) as (33) returns to the rear. While the bearing (34) and the bearing guide block (35) are in contact with each other, the bearing guide block (35) prevents the spring from being restored, so the protrusion of the support auxiliary member (30) (31) is retained. When the rotation is stopped in a state where the bearing (34) is in contact with the side surface (36b) on the short side, the support auxiliary members (30) and (31) are fixed at a predetermined protruding amount. Conversely, if the bearing (34) contacts the short side surface (36b) and the support auxiliary member (30) (31) protrudes, the rotating table (22) rotates to rotate the bearing (34). On the inclined side surface (36c), it proceeds toward the long side surface (36a). During this time, the slider (33) gradually moves backward without sudden retreat due to the restoring force of the reduced spring and the restoring prevention force by the inclined side surface (36c), and the amount of protrusion decreases. When the bearing (34) reaches the side surface (36a) on the long side, the support auxiliary members (30) and (31) are immersed behind the positioning plate (23). Further, even when the bearing (34) is separated from the bearing guide block (35), the restoring force of the spring is used, so that the immersion state is maintained. Further, since the bearing guide block (35) is a trapezoidal column, the support auxiliary members (30) (31) can be stably projected and retracted as described above regardless of the rotation direction of the rotary table (22).

  As described above, the supporting auxiliary members (30) and (31) protrude from the positioning plate (23) when they are at the position of 180 ° and the vicinity thereof, and are immersed from the positioning plate (23) when they are at other positions. . The maximum protrusion of the support auxiliary member (30) (31) is set by the height of the trapezoid of the bearing guide block (35) (the distance between the long side and the short side), and the angle region that holds the maximum protrusion is It is set by the length of the short side.

  In this embodiment, since two supporting auxiliary members (30) and (31) having the same structure are installed at intervals of 180 ° in the circumferential direction, both supporting auxiliary members (30) and (31) are 180 °. At this position, it protrudes from the positioning plate (23), and at this time, the other supporting auxiliary members (31) and (30) are at a position of 0 ° and are immersed from the positioning plate (23).

  The reference plate (12) is installed in front of the positioning plate (23) of the work support section (20), and places the sectioned product (1) carried in from the outside to the work support section (20). The sectioned product (1) to be held is positioned in the Z-axis direction.

  The deburring brush (13) is attached to the lower end of a spindle (14) that can be moved up and down in the Z-axis direction, retracts above the workpiece support (20), and descends during processing to the workpiece support (20). Deburring the upper surface of the supported section cut product (1) in the support posture.

[Deburring process]
A series of operations at the time of deburring the two cut surfaces (4a) and (4b) of the section cut product (1) using the deburring device (10) described above will be described.

  In the following description, for convenience of explanation, the two cut surfaces of the section cut product (1) are referred to as a first cut surface (4a) and a second cut surface (4b), and two workpiece support portions (20) are provided. The support auxiliary members are referred to as a first support auxiliary member (30) and a second support auxiliary member (31).

(1) See FIGS. 2A and 2B The rotary table (22) is stopped. In the work support (20), the first support auxiliary member (30) is positioned at 180 °, and the bearing (34) is positioned by contacting the side surface (36b) on the short side of the bearing guide block (35). Projecting forward from the plate (23). On the other hand, the second support auxiliary member (31) is at a position of 0 ° and is immersed from the positioning plate (23). The deburring brush (13) is retracted upward.

(2) Refer to FIG. 2A and FIG. 2B. The section cut product (1) is carried into the deburring device (10) from the outside. The section cut product (1) is held by the robot hand (15) and loaded, and the reference plate is placed with the back of the plate (2) facing the work support (20) and the first cutting surface (4a) facing down. (12) Mounted on top.

(3) See FIGS. 4A and 4B The robot hand (15) re-grips the sectioned product (1) placed on the reference plate (12) and carries it to the work support (20). When the back surface of the plate (2) of the section cut product (1) is brought into contact with the front surface (23a) of the positioning plate (23), a part of the first cut surface (4a) becomes the first support auxiliary member (30). And overlap. Immediately after the robot hand (15) releases the section cut product (1), the suction device is operated to adsorb the plate (2) to the tip suction section (29) and hold the section cut product (1). . A state in which the first cut surface (4a) faces downward is defined as a first support posture. At the time of delivery of the cut shape product (1), the cut shape product (1) is temporarily supported from below by the first support auxiliary member (30). Even if there is a slight time lag between the adsorbing and holding due to, it is possible to prevent the sectioned product (1) from falling.

(4) See FIG. 5 In the first support posture, the spindle (14) is lowered so that the deburring brush (13) contacts the second cut surface (4b) of the profiled cut product (1), and the brush Rotate (13) to deburr the second cut surface (4b). At this time, since the second support auxiliary member (31) is immersed and the entire surface of the second cut surface (4b) is exposed, the second cut surface (4b) is deburred all over.

(5) Raise the spindle (4) and retract the deburring brush (13) upward.

(6) The rotary table (22) is rotated by 180 ° while holding the sectioned product (1) with the suction device, so that the second support posture is set with the second cut surface (4b) facing downward.

(7) See FIG. 6 The rotation of the rotary table (22) in (6) above causes the first support auxiliary member (30) to move away from the positioning plate (23) because the bearing (34) is separated from the bearing guide block (35). The first cut surface (4a) of the sectioned product (1) that has been immersed and has reached the position of 0 ° is exposed entirely. On the other hand, the second support auxiliary member (31) that has come to the 180 ° position protrudes from the positioning plate (23) because the bearing (34) is in contact with the bearing guide block (35), and one of the second cut surfaces (4b). It overlaps with the department.

(8) In the second supporting position, the spindle (14) is lowered so that the deburring brush (13) is in contact with the first cut surface (4a) of the sectioned product (1), and the brush is rotated. To deburr the first cut surface (4a). At this time, since the first support auxiliary member (30) is immersed and the entire surface of the first cut surface (4a) is exposed, deburring is performed throughout.

(9) The spindle (14) is raised, and the deburring brush (13) is moved away from the sectioned product (1).

(10) Move the robot hand (15) closer to the sectioned product (1), hold the sectioned product (1) with the robot hand (15), and release the suction by the suction device. At the time of delivery of this section cut product (1), the section cut product (1) is temporarily supported by the second supporting auxiliary member (31) from below, so that the suction release of the suction device and the robot hand (15) Even if there is a slight time lag between gripping and cutting, it is possible to prevent the sectioned product (1) from falling.

  Since the deburring device (10) of the present embodiment includes two supporting auxiliary members (30) and (31), the deburring device (31) is provided at the time of deburring the second cut surface (4b). Supported. For this reason, when the processing is finished, the sectioned product (1) can be transferred to the robot hand (15) in the second support posture. Since it is not necessary to rotate again for delivery of the section cut product (1) to return to the first support posture, delivery can be performed efficiently.

(11) The sectioned product (1) is unloaded from the deburring device (10) by the robot hand (15).

(12) Since the second support auxiliary member (31) is at a position of 180 °, after carrying out the processed shaped material cut product (1), the next step is performed without rotating the support portion. Can accept cut parts. Then, after returning to the above (1), deburring of the next cut product is performed.

  As described above, in the two support postures, one of the support auxiliary members is always at a position of 180 ° and can support the workpiece, and after the workpiece is unloaded, the next workpiece can be received in the same posture. For this reason, a plurality of workpieces can be processed continuously and efficiently.

  In the work support mechanism described above, if the support auxiliary members (30) and (31) protrude even slightly from the front surface (23a) of the positioning plate (23), that is, the suction holding part (28) by the suction device, the work (shape member) Therefore, the present invention does not define the amount of protrusion of the support auxiliary members (30) and (31). However, in order to stably support and prevent the workpiece from falling, it is preferable that the tip of the support auxiliary member protrudes to the center of gravity of the workpiece or protrudes beyond the center of gravity.

  The workpiece support mechanism and the deburring device of the present invention are not limited to the above-described embodiments, and can be appropriately changed without departing from the configuration of the present invention. Below, the modification which can be employ | adopted in this invention is demonstrated.

  There is no restriction | limiting in the number of support auxiliary members, At least 1 should just exist and 3 or more can also be provided. The number of supporting auxiliary members can be appropriately set according to the shape of the workpiece, the position of the processed surface, and the number of processed surfaces.

  The deburring device described above performs deburring of the upper surface of the workpiece in a support posture, and the two side surfaces (cut surfaces (4a) and (4b)) that are opposed to each other in a square shape are the machining surfaces. Two supporting auxiliary members are installed at intervals of 180 ° in the direction, and these are configured to support the cut surfaces (4a) and (4b). As a result, when one processing surface is at a position of 0 °, the other cut surface is supported by the supporting auxiliary member, so that when the second surface is processed, the workpiece can be transferred in the same posture. it can. If there is only one supporting auxiliary member, if the workpiece is transferred after the second surface has been processed, the rotating table must be rotated to return the supporting auxiliary member to the 180 ° position. That is, by providing two supporting auxiliary members, one process can be reduced, and workpiece transfer can be performed efficiently. Conversely, if the number of steps is increased, the number of supporting auxiliary members can be reduced.

  Thus, by arranging a plurality of support auxiliary members in the circumferential direction of the rotation of the support member, the work can be supported in a plurality of support postures, so versatility can be improved. For example, when machining a plurality of surfaces of a workpiece, by providing two supporting auxiliary members at positions where they can be supported in the support posture of the workpiece to be subjected to the first and last machining, the carried workpiece is subjected to the first machining. Processing is carried out in the support posture, and when the last processing is completed, the holding release for carrying out can be released in the same support posture. As a result, the versatility can be improved and the number of steps during workpiece transfer can be reduced. In addition, since a support auxiliary member is arrange | positioned according to the position of the process surface of a workpiece | work, it is not necessarily 180 degree space | interval like the said embodiment.

  In the present invention, since the number of supporting auxiliary members is not limited, the supporting auxiliary members can be appropriately provided according to the shape of the workpiece and the number and position of the processed surfaces. One surface of the workpiece may be supported by a plurality of supporting auxiliary members. Further, the shape of the support auxiliary member is not limited to a flat plate, and can be appropriately changed according to the shape of the workpiece.

  There is no limitation on the means for raising and lowering the supporting auxiliary member, and any means can be used. Further, interlocking with the rotation of the support portion is not an essential requirement of the present invention. Further, when the supporting auxiliary plate is in the lower position, it is sufficient that it protrudes when the workpiece is transferred, and it may be in any state other than the time when it is transferred. In the deburring apparatus of the above-described embodiment, the support auxiliary member at the 180 ° position is protruded except during the delivery, because the upper surface of the workpiece in the support posture is configured to be deburred. This is because even if the supporting auxiliary member protrudes, the processing is not disturbed. Needless to say, the support auxiliary member is immersed when processing from below. In addition, the reason why one of the two supporting auxiliary members protrudes and the other is immersed is because the processing surfaces of the workpiece are two opposing side surfaces and the processing surface is directed upward. That is, when one of the machining surfaces is being machined, the other machining surface is always directed downward, so that the support auxiliary member other than the 180 ° position must be immersed for machining. However, depending on the setting of the number of support auxiliary members, the shape of the workpiece, the number and position of the processing surface, and the processing direction, a support auxiliary member other than the 180 ° position (support auxiliary member not supporting the lower support) may interfere with the processing. It may not be. The present invention is not limited to immersing the auxiliary support member other than the 180 ° position, and the setting of the intrusion is arbitrary as long as it does not interfere with the processing.

  Further, the support posture and the machining direction at the time of machining the workpiece are not limited, and the present invention includes a case where machining is performed from below, side, oblique, and front. The stop angle of the workpiece support part can be freely set, and the support angle of the workpiece can also be freely set. Therefore, the support posture and the machining direction may be set according to various conditions such as the shape of the workpiece and the type of machining. However, when deburring is performed with a brush as in the above embodiment, if the removed burr or processing lubricant falls and accumulates on the brush, it may cause processing defects due to clogging. It is preferable to deburr the upper surface. Furthermore, the deburring tool is not limited to a brush, and other deburring tools such as a polishing sheet can be used as appropriate.

  The work holding means is not limited to suction. The present invention also includes a case of holding by other means such as gripping as long as the processing is not hindered.

  Furthermore, the workpiece support mechanism of the present invention is not limited to the deburring device, and can be used in general when the workpiece needs to be held in a predetermined posture for processing or work. Replacing the deburring tool with another processing tool can be used for a wide variety of processing and work. The shape of the workpiece is not limited, and the support posture (angle) can be arbitrarily set, so that the support mechanism is highly versatile. Furthermore, since the versatility is high, it is easy to automate a series of operations such as workpiece loading, machining, and machining of workpieces being unloaded.

  Since the present invention is a versatile workpiece support mechanism, it can be used for various processes.
