Embodiments for Carrying Out the Invention
[0009] Embodiments will be described with reference to the drawings. In the description of the drawings, the same reference numerals are given to the same parts and the description thereof is omitted.
[0010] [Configuration of Deburring Device 1] With reference to FIGS. 1 to 15, the configuration of the deburring device 1 according to the present embodiment will be described. In this specification, the front of the deburring device 1 as seen from an operator stepping on an operation pedal 53 to be described later is taken as the front of the deburring device 1.
[0011] As shown in FIGS. 1 to 4, the deburring device 1 includes a drum part (cylindrical part 2), a main body frame 3, an input chute 4, a clamp mechanism (holding portion 5), a nozzle 6, a brush 7, an operation unit 8, a link mechanism (drive mechanism 9), and a payout chute 10.
[0012] The cylindrical part 2 shown in FIGS. 5 and 6 constitutes a workpiece (object) in the deburring device 1. For example, it is a part of a clutch of a vehicle (clutch case). This cylindrical part 2 is processed from a flat plate by press forming, and fibrous burrs 16 can adhere to the axial end portions 11 of the cylindrical part 2 due to static electricity or the like (see FIG. 6). Further, a plurality of convex portions 14, 15 are provided on the outer peripheral surface 12 and the inner peripheral surface 13 of the cylindrical part 2 at intervals in the circumferential direction of the cylindrical part 2.
[0013] In one embodiment, the cylindrical component 2 may be other than a component (clutch case) of the vehicle clutch. Further, in another embodiment, the plurality of convex portions 14 and 15 may be provided only on either the outer peripheral surface 12 or the inner peripheral surface 13 of the cylindrical component 2.
[0014] The main body frame 3 is configured to include a plurality of column portions 21, a top plate portion 22, a plurality of beam portions 23 and 24, and a shelf portion 25. Column portions 21 are respectively arranged at each corner of a quadrangle in plan view, and the top plate portion 22 is bridged over the upper ends of these column portions 21. Further, an upper beam portion 23 and a lower beam portion 24 are attached to an intermediate portion in the height direction (vertical direction) of the column portions 21. A shelf portion 25 is bridged over the upper beam portion 23, and a support portion 26 which is formed in a substantially L shape in side view and supports an operation pedal 53 or the like is connected between this shelf portion 25 (or the upper beam portion 23) and the lower beam portion 24. Further, a through hole 22h through which a clamp rod 42 described later is inserted is formed in the top plate portion 22, and a through hole 25h through which a pipe 61 described later is inserted is formed in the shelf portion 25.
[0015] The charging chute 4 is configured to include a base portion 31, a bottom plate portion 32, and a pair of side plate portions 33 and 33. The base portion 31 is arranged on the top plate portion 22 of the main body frame 3, and the bottom plate portion 32 and the pair of side plate portions 33 and 33 are arranged above the base portion 31. The bottom plate portion 32 is formed of, for example, an embossed steel plate, and a substantially U-shaped charging path is formed by the bottom plate portion 32 and the pair of side plate portions 33 and 33. Further, a through hole 32h through which a stopper 38 described later is inserted is formed in the bottom plate portion 32 (see FIGS. 7 to 9).
[0016] The holding portion 5 is configured to have a clamp portion 41 that clamps the cylindrical part 2 from the inner circumferential surface 13 side of the cylindrical part 2 (see Figures 10 to 12). This clamp portion 41 is configured to have a clamp rod 42, a flange 43, a plurality of links 44, and a cylindrical member 45. The flange 43 is attached to the upper end of the clamp rod 42, and this clamp rod 42 extends downward through the through hole 22h of the top plate portion 22 of the main frame 3 and is further inserted into the pipe 61.
[0017] The lower end of the clamp rod 42 protrudes from the lower end of the pipe 61 and is connected to the output shaft 74 of the gearbox 72, which will be described later. The upper end of the cylindrical member 45 is provided with multiple extensions 46 that extend radially outward from the cylindrical member 45, and a link 44 is rotatably supported on each extension 46 (see Figures 10 to 12). One end of the link 44 abuts against the flange 43, and the other end of the link 44 is fitted with a pad 47 that abuts against the inner circumferential surface 13 of the cylindrical part 2 when clamped by the clamp portion 41. The lower end of the cylindrical member 45 is attached to the top plate portion 22 of the main frame 3 via a bearing 48, and a spring 77 is positioned between the bearing 48 and the flange 43 to bias the flange 43 upward.
[0018] When rotation is applied to the clamp rod 42, the flange 43, link 44, and cylindrical member 45 rotate together with the clamp rod 42. Also, when the clamp rod 42 is pushed down, the flange 43 causes the link 44 to rotate, and the pad 47 at the tip of the link 44 clamps the cylindrical part 2.
[0019] Furthermore, a large-diameter portion 49, which is made up of a nut or the like, is provided in the clamp rod 42 at the portion located between the top plate portion 22 of the main frame 3 and the pipe 61.
[0020] The nozzle 6 blows air as a gas onto a plurality of protrusions 14 provided on the outer circumferential surface 12 of the cylindrical part 2 held by the holding part 5. In this embodiment, the nozzle 6 is positioned so that its tip faces the outer circumferential surface 12 and the axial end 11 of the cylindrical part 2 (see Figures 13 and 14). By blowing air onto the plurality of protrusions 14 with the nozzle 6, the cylindrical part 2 is rotated around its central axis, and the blown air removes the burrs 16. The tip of this nozzle 6 is a wide-spray type with a wide spraying range in the vertical direction.
[0021] In one embodiment, the nozzle 6 that blows air may be positioned on the inner circumferential surface 13 side of the cylindrical part 2, or the nozzle 6 may be positioned on both the outer circumferential surface 12 side and the inner circumferential surface 13 side of the cylindrical part 2. In another embodiment, the gas that the nozzle 6 blows onto the cylindrical part 2 may be something other than air. In yet another embodiment, an imaging unit such as a camera that images the axial end 11 of the cylindrical part 2 may be provided for the purpose of confirming whether or not the burrs 16 have been properly removed.
[0022] Furthermore, a switch 51 for switching the air blown from the nozzle 6 on and off is located below the frame 62 (described later) and positioned on the shelf 25 of the main frame 3. Therefore, when the frame 62 is lowered, the switch 51 is turned on by the frame 62, and air is blown from the nozzle 6 towards the cylindrical part 2.
[0023] The brush 7 is positioned to contact the axial end 11 of the cylindrical part 2, which is held by the holding part 5 (see Figures 13 and 14). This brush 7 is a so-called channel brush, and the brush portion is made of a metal material such as brass. The brush 7 is also supported by a support column (not shown) positioned on the top plate portion 22 of the main frame 3. In the illustrated example, the brush 7 is positioned below the axial end 11 of the cylindrical part 2 so that its brush portion contacts the axial end 11 of the cylindrical part 2 from below (see Figures 13 and 14).
[0024] Furthermore, a magnet 52 is positioned on the top plate portion 22 of the main frame 3 to suppress the scattering of burrs 16 removed by the air blown by the nozzle 6 and the brush 7 (see Figures 13 and 14).
[0025] In one embodiment, the brush 7 may be positioned to the side of the axial end 11 of the cylindrical part 2 such that its brush portion contacts the axial end 11 of the cylindrical part 2 from the side (see Figure 15). This brush 7 is configured such that, for example, a link mechanism (not shown) is connected to its handle portion, and this link mechanism brings it closer to the cylindrical part 2 as the deburring stage 81 descends. Furthermore, a brush 17, so-called a wheel brush, may be positioned below the axial end 11 of the cylindrical part 2 such that its brush portion contacts the axial end 11 of the cylindrical part 2 from below (see Figure 15). This brush 17 is biased upward by, for example, a spring (not shown). Note that in Figure 15, the nozzle 6 and magnet 52, etc., are omitted from the illustration.
[0026] The operating unit 8 is configured to have an operating pedal 53 that is operated by the operator stepping on it. The base end 53a of the operating pedal 53 is mounted on the support portion 26 of the main frame 3 so as to be able to swing up and down, and the tip portion 53b of the operating pedal 53 has a stepping portion 54 that is stepped on by the operator. Furthermore, an elongated hole 56 is formed in the portion between the base end 53a and the tip portion 53b of the operating pedal 53, through which a shaft portion 55 attached to the pipe 61 is slidably inserted.
[0027] The pipe 61 extends vertically through a through-hole 25h in the shelf section 25 of the main frame 3, and a frame 62, which is roughly rectangular in shape when viewed from the side, is attached to the upper end of the pipe 61. Springs 63 and 64 are placed between the frame 62 and the top plate section 22 of the main frame 3, and between the frame 62 and the shelf section 25 of the main frame 3, respectively, and these springs 63 and 64 bias the pipe 61 and the operating pedal 53 upward. Furthermore, a roller 65 is also placed on the support section 26 of the main frame 3 so as to contact the lower end of the pipe 61 that moves in the vertical direction. When the operating pedal 53 is pressed by the operator, the pipe 61 and the frame 62 attached to the upper end of the pipe 61 are lowered against the biasing force of the springs 63 and 64.
[0028] Furthermore, the lower end of the rod 67 is fixed to a tab 66 provided on the frame 62, and the upper end of the rod 67 is fixed to a tab 85 provided on the deburring stage 81, which will be described later. Therefore, when the operator presses the operating pedal 53, the deburring stage 81 is lowered together with the pipe 61 and the frame 62.
[0029] The drive mechanism 9 is configured such that the cylindrical component 2 is supplied to the holding part by moving the operating part 8 from a first position (see Figure 2) to a second position with a single operation by the operator. The drive mechanism 9 is also configured such that the holding part 5 holds the cylindrical component 2 and the nozzle 6 blows gas onto the multiple protrusions 14 with a single operation by the operator moving the operating part 8 from a second position to a third position (see Figure 3). Furthermore, the drive mechanism 9 is configured such that the cylindrical component 2 is removed from the holding part 5 by moving the operating part 8 from a third position to a first position with the release of a single operation by the operator.
[0030] Furthermore, the drive mechanism 9 has a torque application mechanism 71 that applies rotational torque to the holding part 5 by moving the operating part 8 from the second position to the third position.
[0031] The torque application mechanism 71 has a gearbox 72, also known as an L-shaped adapter. The input shaft 73 of this gearbox 72 is fitted with a pinion 36 of a rack and pinion mechanism 35, and the aforementioned clamp rod 42 is connected to the output shaft 74 of the gearbox 72. In order to prevent the vertical movement of the clamp rod 42 from being transmitted to the output shaft 74 of the gearbox 72, in this embodiment, for example, the connection portion 75 between the clamp rod 42 and the output shaft 74 is connected by a spline connection.
[0032] In one embodiment, the connection portion 75 between the clamp rod 42 and the output shaft 74 may be connected via a clutch or the like. In another embodiment, a ratchet mechanism or a one-way clutch mechanism that transmits rotation in only one direction from the input shaft 73 to the output shaft 74 may be arranged inside the gearbox 72.
[0033] Furthermore, the input shaft 73 of the gearbox 72 is supported by a roughly crank-shaped bracket 76 attached to the lower beam 24 of the main frame 3. The rack 37 of the rack and pinion mechanism 35 is positioned at the lower end of a stay 68 attached to the pipe 61, and this stay 68 moves vertically along a guide 69 located on the support portion 26 of the main frame 3. When the operator presses the operating pedal 53, the stay 68 and rack 37 are lowered together with the pipe 61 and frame 62, and this lowering rack 37 rotates the pinion 36. This rotation of the pinion 36 of the rack and pinion mechanism 35 imparts initial rotation to the clamp rod 42 via the input shaft 73 and output shaft 74 of the gearbox 72.
[0034] Furthermore, on the top plate portion 22 of the main frame 3, there is a deburring stage 81 on which the holding portion 5 is positioned, and a dispensing plate 82 for dispensing the cylindrical parts 2 from the deburring stage 81. This dispensing plate 82 is mounted so as to be tiltable relative to the deburring stage 81, with the end on the dispensing chute 10 side as the pivot point.
[0035] The deburring stage 81 and the dispensing plate 82 each have openings 81a and 82a, respectively, to accommodate the clamp portion 41 of the holding portion 5 on the inside. In addition, a notch 82b is formed on the periphery of the opening 82a of the dispensing plate 82, through which the outlet-side stopper 27, which is placed on the top plate portion 22 of the main frame 3, is inserted.
[0036] The dispensing plate 82 has a pair of side wall portions 83, 83 and an inlet-side stopper 84. In other words, the inlet-side stopper 84, which is located on the input chute 4 side, is positioned on the dispensing plate 82, while the plate-shaped outlet-side stopper 27, which is located on the dispensing chute 10 side, is positioned on the top plate portion 22 of the main frame 3.
[0037] Furthermore, a pair of tabs 85, 85 are provided on the side of the deburring stage 81, and the upper ends of rods 67 extending from the frame 62 are fixed to each of these tabs 85, 85. Therefore, when the operator presses the operating pedal 53, the deburring stage 81 is lowered together with the pipe 61 and the frame 62.
[0038] A link 86 is positioned between the deburring stage 81 and the top plate portion 22 of the main frame 3 (see Figures 7 to 9). This link 86 moves vertically along a guide 34 attached to the base 31 of the input chute 4. The link 86 is also biased upward by a spring 87 attached to the base 31 of the input chute 4, and this upward movement of the link 86 is restricted by a stopper 89 provided on the base 31 of the input chute 4. Furthermore, one end of the link 86 abuts against the lowered deburring stage 81, and a rod 39 with a stopper 38 attached to its upper end is attached to the other end of the link 86.
[0039] Therefore, when the operator presses the operating pedal 53, the deburring stage 81 is lowered, and the deburring stage 81 pushes down the link 86, causing the rod 39 and stopper 38 to lower. Once the rod 39 and stopper 38 have lowered and the stopper 38 has been pulled out through the through hole 32h in the bottom plate portion 32 of the input chute 4, the cylindrical part 2 on top of the bottom plate portion 32 slides along the bottom plate portion 32 and is fed into the aforementioned deburring stage 81.
[0040] An inverted U-shaped intermediate member 91 is positioned in the space between the upper and lower parts of the frame 62, and this intermediate member 91 moves vertically along a guide 28 attached to the lower surface of the top plate portion 22 of the main frame 3. In addition, the intermediate member 91 is biased upward by a spring (not shown), similar to the link 86 on the dispensing plate 82 side, and the upward movement of this intermediate member 91 is restricted by a stopper (not shown).
[0041] Therefore, when the operator presses down the operating pedal 53 and the pipe 61 and frame 62 are lowered, the frame 62 pushes down the intermediate member 91, which in turn pushes down the large-diameter portion 49 of the clamp rod 42. Then, as described above, when the clamp rod 42 is pushed down, the flange 43 causes the link 44 to rotate, and the pad 47 at the tip of the link 44 clamps the cylindrical part 2 (see Figure 12).
[0042] The dispensing plate 82 is tiltably mounted relative to the deburring stage 81. When the deburring stage 81 rises from its lowered position, the end of the dispensing plate 82 on the dispensing chute 10 side comes into contact with a stopper 29 placed on the top plate portion 22 of the main frame 3, causing the dispensing plate 82 to tilt relative to the deburring stage 81. In this state, the cylindrical part 2 is dispensed from the deburring stage 81 by the dispensing plate 82 (see Figure 7).
[0043] [Operation of Deburring Device 1] Referring to Figures 7 to 14, an example of the operation of the deburring device 1 in Figure 1 will be explained.
[0044] (1) First stage operation of the operating pedal 53: The cylindrical part 2 is supplied to the holding part 5 by moving the operating unit 8 from the first position to the second position with a single operation by the operator. In other words, the first stage operation by the operating pedal 53 supplies the cylindrical part 2 in the input chute 4 to the holding part 5 and the deburring stage 81, as shown in Figures 7 to 9.
[0045] (2) Second stage operation of the operating pedal 53: A single operation by the operator moves the operating unit 8 from the second position to the third position, causing the holding unit 5 to hold the cylindrical part 2 and the nozzle 6 to blow gas onto the multiple protrusions 14. In other words, the second stage operation of the operating pedal 53 causes the clamping unit 41 to clamp the cylindrical part 2, as shown in Figures 11 to 12, and also causes the nozzle 6 to blow air onto the cylindrical part 2, as shown in Figures 13 to 14. Furthermore, a single operation by the operator moves the operating unit 8 from the second position to the third position, which also applies rotational torque (initial rotational force) to the holding unit 5 by the torque application mechanism 71.
[0046] (3) Releasing the operation on the operating pedal 53: Releasing one operation by the operator causes the operating unit 8 to move from the third position to the first position, which removes the cylindrical part 2 from the holding unit 5. In other words, releasing the operation on the operating pedal 53 releases the clamp on the cylindrical part 2 by the clamping unit 41, the deburring stage 81 rises, and the cylindrical part 2 is discharged from the deburring stage 81 to the discharge chute 10.
[0047] (4) Product check: The cylindrical parts 2 dispensed by the dispensing chute 10 are visually checked by the worker. The cylindrical parts 2 that have been visually checked are then stacked appropriately on the product pallet by the worker.
[0048] In summary, the deburring device 1 according to this embodiment is a device that uses human power (the strength of a worker) as a power source, transmits the driving force through a link mechanism and gears to generate a series of operations, and removes burrs 16 by automatic rotation.
[0049] [Effects and Effects] The effects and advantages of this embodiment will be described below.
[0050] (1) The deburring device 1 is a device for removing fibrous burrs 16 attached to a cylindrical part 2 which has a plurality of protrusions 14, 15 on its outer surface 12 or inner surface 13. The deburring device 1 comprises a holding part 5 that holds the cylindrical part 2 so that it can rotate around the central axis of the cylindrical part 2, and a nozzle 6 that blows gas onto the plurality of protrusions 14, 15 of the cylindrical part 2 held by the holding part 5. By blowing gas onto the plurality of protrusions 14, 15 with the nozzle 6, the cylindrical part 2 is rotated around the central axis of the cylindrical part 2, and the burrs 16 are removed by the blown gas.
[0051] According to the deburring device 1 of this embodiment, burrs 16 can be removed (deburred) from the entire outer circumference of the cylindrical part 2 (drum part) by blowing gas, without requiring a conventional conveying device or a drive device (actuator) such as a robot. Therefore, it is possible to provide a deburring device 1 that does not require a conveying device or a drive device such as a robot, thereby reducing the introduction cost.
[0052] (2) The deburring device 1 includes a brush 7 that is positioned to contact the axial end 11 of the cylindrical part 2 held by the holding part 5.
[0053] According to the deburring device 1 of this embodiment, burrs 16 can be removed by blowing air, as well as by using a brush 7. Therefore, it becomes possible to remove burrs 16 that may adhere to the axial end 11 of the cylindrical part 2 more efficiently.
[0054] (3) The deburring device 1 includes an operating unit 8 that moves from a first position to a third position via a second position with a single operation by the operator, and moves from the third position to the first position when the operator releases a single operation by the operator, and a drive mechanism 9 connected to the operating unit 8. The drive mechanism 9 is configured such that the cylindrical part 2 is supplied to the holding unit when the operating unit 8 moves from the first position to the second position with a single operation by the operator. The drive mechanism 9 is also configured such that the holding unit 5 holds the cylindrical part 2 and the nozzle 6 blows gas onto the multiple protrusions 14, 15 when the operating unit 8 moves from the second position to the third position with a single operation by the operator. Furthermore, the drive mechanism 9 is configured such that the cylindrical part 2 is removed from the holding unit 5 when the operating unit 8 moves from the third position to the first position when the operator releases a single operation by the operator.
[0055] According to the deburring device 1 of this embodiment, a worker can perform a series of operations on the operating unit 8 (operating pedal 53) to supply (feed in) the workpiece (cylindrical part 2), remove the burrs 16, and remove (dispatch) the cylindrical part 2. Therefore, it is possible to reduce the amount of work required by the worker to remove the burrs 16.
[0056] (4) The drive mechanism 9 has a torque application mechanism 71 that applies rotational torque to the holding part 5 by moving the operating part 8 from the second position to the third position.
[0057] According to the deburring device 1 of this embodiment, the supply pressure or amount of gas from the nozzle 6 can be reduced compared to the case in which the cylindrical part 2 is rotated by blowing air alone. Therefore, it is possible to provide a deburring device 1 that can reduce not only the initial cost but also the operating cost.
[0058] (5) The deburring device 1 comprises a deburring stage on which the holding part 5 is arranged, and a dispensing plate 82 for dispensing the cylindrical part 2 from the deburring stage 81.
[0059] According to the deburring device 1 of this embodiment, the cylindrical parts 2 can be easily dispensed from the deburring stage 81 by the operation of the dispensing plate 82. This makes it possible to reduce the amount of work required for the operator to remove burrs.
