Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a deburring apparatus for removing burrs produced on splines and threads of shafts.

  For example, a screw portion or a spline portion may be formed by cutting on an outer peripheral surface of an output shaft of a transmission of a car. In this case, since burrs are generated in the screw portion and the spline portion, it is necessary to remove the burrs.

  In the past, burrs of the threaded portion and spline portion of the shaft as described above have been manually removed by a worker using a wire brush. As described above, it is troublesome and time-consuming for the worker to hold the shaft and remove the burrs one by one, and therefore, an apparatus for automatically removing the burr has been desired.

  For example, Patent Document 1 below shows a deburring apparatus that automatically removes burrs produced on the thread portion of a workpiece. Further, Patent Document 2 below shows a deburring apparatus for automatically removing burrs generated in a spline portion of a work.

  However, if the deburring device for removing the burrs of the screw portion as described above and the deburring device for removing the burrs of the spline portion are separately provided, the equipment cost is increased and the number of man-hours is increased to increase productivity. descend.

  The inventor examined an apparatus capable of simultaneously removing burrs generated on the threaded portion and the spline portion of the shaft. Specifically, by reciprocating the shaft in the direction orthogonal to the axial direction and bringing the wire brush provided on the fixed side into contact with the screw portion and spline portion of the reciprocating shaft, the screw portion and the spline portion are I tried to remove the burrs. As a result, although the burrs of the screw portion could be removed, the burrs of the axial groove (spline portion) extending in the direction orthogonal to the moving direction of the shaft could not be sufficiently removed.

  Therefore, it is an object of the present invention to provide a deburring apparatus capable of simultaneously and reliably removing burrs generated in axial grooves (such as splines) of shafts and other cutting parts (such as threaded parts). To aim.

  In order to solve the above problems, the present invention provides a plurality of axial grooves provided on the outer peripheral surface of the shaft at equal intervals in the circumferential direction and deburring for removing burrs of a cutting portion axially separated therefrom. An apparatus, comprising: a fixed body; a movable body in which the shaft is set and capable of reciprocating relative to the fixed body in a direction orthogonal to the axial direction of the shaft; and driving means for reciprocating the movable body. The fixed brush provided on the fixed body and in contact with the cutting portion of the shaft set on the reciprocating moving body, and the movable brush provided on the movable body and reciprocating in the axial direction of the shaft A deburring device is provided which comprises a movable brush in contact with a groove.

  In this manner, the burrs of the cutting portion can be removed by bringing the cutting portion (for example, the screw portion, the gear portion, etc.) into contact with the fixed brush while reciprocating the shaft in the direction orthogonal to the axial direction. it can. In addition, the movable brush slides along the extending direction of the axial groove by bringing the movable brush provided on the moving body into contact with the axial groove while reciprocating in the axial direction, and burrs of the axial groove It can be removed reliably.

  For example, burrs in the axial groove on the entire circumference of the shaft can be removed by rotating the shaft little by little while bringing the axially reciprocating movable brush into contact with the axial groove of the shaft. At this time, if the shaft is rotated while the tip of the movable brush is in the axial groove, the rotation of the shaft is inhibited and the movable brush may be damaged. Therefore, the shaft can be rotated smoothly by rotating the shaft by a predetermined angle in a state where the movable brush is separated from the axial groove, and damage to the movable brush can be prevented.

  Preferably, the deburring apparatus is provided with a brush drive mechanism for reciprocating the movable brush in the axial direction of the shaft by using the movement of the movable body. As a result, the movable brush can be reciprocated in the axial direction without requiring a separate drive means, so that the deburring apparatus can be simplified and downsized. The brush drive mechanism includes, for example, a gear provided on the moving body, a rotational driving unit that meshes with the gear and rotates the gear according to the reciprocation of the moving body, and rotational movement of the gear in the axial direction of the movable brush. A link mechanism may be provided that converts to a reciprocating motion. In this case, when the movable body is moved, the gear is rotated by the rotational drive unit, and this rotational movement is converted to the reciprocating movement of the movable brush through the link mechanism.

  For example, a rack fixed to a fixed body can be provided as the above-mentioned rotation drive unit. In this case, the movable brush is axially reciprocated via the link mechanism by the rotation of the gear engaged with the rack along with the movement of the movable body. In addition, as a rotational drive unit, a loop chain may be provided, which is spanned by a plurality of pulleys separated in the moving direction of the movable body. In this case, a part of the loop chain is fixed to the moving body, and the other region of the loop chain runs in the direction opposite to the moving direction of the moving body while meshing with the gear, in addition to the moving amount of the moving body. The gears are rotationally driven by the amount of movement of other regions of the loop chain traveling in the opposite direction. As a result, the number of rotations of the gear is doubled as compared with the case where a rack is provided as a rotational drive unit, so the frequency of reciprocating movement of the movable brush is also doubled, and the efficiency of burr removal in the spline portion is enhanced. Be

  For example, a cylinder can be used as drive means for reciprocating the moving body. At this time, if the pin of the cylinder and the moving body are directly connected by a string member such as a chain, the cylinder having a stroke equivalent to the stroke of the moving body is required. Cause. Therefore, the driving means includes a string-like member whose one end is fixed to the moving body and the other end is fixed to the fixed body, a moving pulley provided at the folded portion of the string-like member, and a cylinder for moving the moving pulley. It is preferable to have the configuration provided. In this case, moving the moving pulley with the cylinder and pulling the folded portion of the chain moves the moving body by twice the stroke of the cylinder. As a result, since the stroke of the cylinder is half of the stroke of the moving body, it is possible to shorten the length of the cylinder and miniaturize the apparatus.

  As described above, according to the deburring apparatus of the present invention, burrs generated in axial grooves (spline parts etc.) and other cutting parts (screw parts etc.) provided on the shaft can be removed simultaneously and reliably. can do.

  As shown in FIG. 2, a shaft 100 is set to the movable body 3. In the illustrated example, the two shafts 100 are set on the movable body 3 in a standing state. At axially intermediate portions of the outer peripheral surface of the shaft 100, spline portions 101 are provided as a plurality of axial grooves provided at equal intervals in the circumferential direction.

Specifically, splines 101 are provided on the cylindrical outer peripheral surface of the shaft 100 by forming a plurality of axial grooves at equal intervals in the circumferential direction by cutting. Another cutting portion is provided in a region axially separated from the spline portion 101 of the shaft 100. In the present embodiment, cutting portions are provided at the upper end and the lower end of the shaft 100, respectively. Specifically, a threaded portion 102 is provided at the upper end of the shaft 100, and a gear portion 103 (helical gear in the illustrated example) is provided at the lower end of the shaft 100.

  The movable body 3 has a base 3a, a support 3b extending upward from the base 3a, and a beam 3c extending horizontally from the vicinity of the upper end of the support 3b. The movable body 3 is movable in a direction orthogonal to the axial direction of the shaft 100 (left-right direction in FIG. 1, right-angled direction in FIG. 2). Specifically, a roller 3 d traveling on the rail 2 a is provided on the lower surface of the base 3 a of the movable body 3. The movable body 3 is movable in the moving direction by the roller 3 d traveling on the rail 2 a while being guided in the moving direction by a guide not shown. In the following, the moving direction (left and right direction in FIG. 1) of the movable body 3 is referred to as “front and back direction”, and the horizontal direction (left and right direction in FIG. 2) orthogonal to the front and rear direction is referred to as “width direction”.

  The movable body 3 is provided with a lower support portion 3 e and an upper support portion 3 f for supporting both axial ends of the shaft 100. The lower support 3e is rotatably provided on the base 3a, and is rotationally driven by an intermittent rotation mechanism 20 described later. The upper support portion 3f is attached to the beam 3c so as to be freely rotatable via a bearing 3g. The upper support portion 3f can be moved up and down by operating a lever (not shown).

  The first fixed brush 5 and the second fixed brush 6 are attached to the frame 2. The first fixed brush 5 is provided at a position in contact with the screw portion 102 of the shaft 100 set in the movable body 3. Specifically, the first fixed brush 5 is provided from outside in the width direction It is provided at the contact position. The second fixed brush 5 is provided at a position in contact with the gear portion 103 of the shaft 100 set in the movable body 3, and specifically, contacts the circumferential partial region of the lower end surface of the gear portion 103 from below. It is provided at the position.

  As shown in FIG. 3, the movable body 3 is provided with a movable brush 7. The movable brush 7 can reciprocate in the axial direction (vertical direction in the illustrated example) of the shaft 100. The movable brush 7 is provided to come into contact with a circumferential partial area of the spline portion 101 of the shaft 100 set on the movable body 3 while reciprocating up and down.

  The deburring apparatus 1 according to the present embodiment is provided with a brush drive mechanism for reciprocating the movable brush 7 up and down using the movement of the movable body 3. In the example of illustration, a brush drive mechanism is comprised by the gear 8 attached to the mobile body 3, the rotational drive part which rotates the gear 8, and the link mechanism 9 which connects the gear 8 and the movable brush 7. FIG. The gear 8 is attached to the base 3 a of the movable body 3 so as to be freely rotatable about a rotation axis in the width direction. The link mechanism 9 converts the rotational movement of the gear 8 into the up and down reciprocating movement of the movable brush 7. In the present embodiment, the link mechanism 9 is configured by a parallel link mechanism having a first link 9a, a second link 9b, a fixed link 9c, and an auxiliary link 9d. One end of the first link 9a is pivotally attached to a mounting portion 8a provided on the rotation shaft of the gear 8, and the other end is pivotally attached to one end of the second link 9b. The middle portion of the second link 9b is pivotally attached to the fixed link 9c fixed to the support via a pin 9e, and the other end of the second link 9b is pivotally attached to the movable brush 7. One end of the auxiliary link 9 d is pivotally connected to the fixed link 9 c, and the other end is pivotally connected to the movable brush 7.

  The rotation drive unit rotates the gear 8 along with the reciprocating movement of the movable body 3. In the present embodiment, the rack 10 is provided as the rotation drive unit (in FIG. 3, only a part of the rack 10 is shown) Yes). The rack 10 is fixed to the frame 2. The rack 10 is provided in the entire range of the longitudinal stroke of the gear 8 accompanying the reciprocating movement of the movable body 3. When the movable body 3 moves forward or backward, the gear 8 engaged with the rack 10 is rotated. Along with this, the first link 9a moves up and down, and the second link 9b swings around the pin 9e, whereby the movable brush 7 reciprocates up and down (see the arrow in FIG. 3).

  The movable body 3 is provided with an intermittent rotation mechanism 20 which periodically rotates the shaft 100 by a predetermined angle. In the present embodiment, as shown in FIG. 2, the intermittent rotation mechanism 20 is fixed to the base 3 a of the movable body 3 and is connected to the lower support 3 e. When the movable body 3 moves and reaches the front end, the shaft 100 is rotated by a predetermined angle (for example, the same angle as the phase difference between adjacent axial grooves of the spline portion 101) by the intermittent rotation mechanism 20.

  The intermittent rotation mechanism 20 rotates the shaft 100 by a predetermined angle while the movable brush 7 is not in contact with the spline portion 101 of the shaft 100. In the present embodiment, when the movable body 3 reaches the front end, the movable brush 7 is disposed at the upper end or the lower end. The movable brush 7 reciprocates up and down along an arc locus centering on the pin 9 e, so that the upper end and the lower end are separated from the outer peripheral surface of the shaft 100 (see FIG. 3). During this time, the shaft 100 is rotated by a predetermined angle by the intermittent rotation mechanism 20.

  As the intermittent rotation mechanism 20, for example, one as shown in FIG. 4 is used. The intermittent rotation mechanism 20 includes a base plate 21, a rotating member 22 rotatably attached to the base plate 21, a gear member 23 rotatable around the rotation center of the rotating member 22, and a pin 25 on the base plate 21. It mainly comprises a parallel link mechanism 24 which is mounted possible. The rotating member 22 is rotatable integrally with the lower support 3e (see FIG. 2).

  The rotating member 22 has an abutting portion 22a and a rotation angle regulating portion 22b. A large number of recesses 23 a are provided on the outer periphery of the gear member 23, and in the present embodiment, the same number of recesses 23 a as the grooves of the spline portion 101 of the shaft 100 are provided. The gear member 23 is attached to the rotating member 22 via a one-way clutch (not shown), and when the rotating member 22 rotates in the forward direction (the arrow Q direction in FIG. 4), the rotating member 22 rotates integrally therewith. When the rotating member 22 rotates in the reverse direction, the rotating member 22 does not rotate but stops in place.

  The parallel link mechanism 24 comprises a pair of parallel first links 24 a and a pair of parallel second links 24 b. The central portion of each second link 24 b is rotatably attached to the base plate 21 via a pin 25. Each first link 24 a is provided with a protrusion 24 a 1, and the protrusion 24 a 1 is fitted in a recess 23 a on the outer periphery of the gear member 23. The pin 25 is inserted into the long hole 22 c provided in the rotation angle regulating portion 22 b of the rotating member 22, and the long hole 22 c and the pin 25 are engaged in the rotation direction of the rotating member 22 to rotate the rotating member 22. The corners are regulated. A tension spring 26 is provided between the contact portion 22a of the rotation member 22 and the base plate 21. The tension spring 26 urges the rotation member 22 to rotate in the reverse direction (the direction opposite to the arrow Q). ing. Further, a tension spring 27 is provided between the first link 24 a of the parallel link mechanism 24 and the base plate 21, and this tension spring 27 causes the pair of first links 24 a of the parallel link mechanism 24 to close (adjacent to each other). Side).

  The driving means 4 reciprocates the moving body 3 in the front-rear direction. In the present embodiment, as shown in FIG. 1, a drive means 4A for moving the movable body 3 forward and a drive means 4B for moving the movable body 3 backward are provided. Each driving means 4 includes a chain 4a as a string-like member, a moving pulley 4b provided at a folded portion of the chain 4a, and a cylinder 4c for moving the moving pulley 4b. One end of the chain 4 a is attached to the moving body 3 and the other end is attached to the frame 2. In the illustrated example, a chain 4a horizontally extending from the moving body 3 extends downward through a fixed pulley 4d provided on the frame 2, and further extends upward through a moving pulley 4b and is fixed to the frame 2 . By lowering the moving pulley 4b with the cylinder 4c, the folded portion of the chain 4a is pulled downward, and the moving body 3 moves. For example, an air cylinder is used as the cylinder 4c.

  Hereinafter, the operation of the deburring apparatus 1 of the above configuration will be described.

  First, as shown in FIG. 2, the shaft 100 is set on the moving body 3. Specifically, in a state in which the shaft 100 is disposed between the lower support 3 e and the upper support 3 f of the movable body 3, the upper support 3 f is lowered and the hole provided in the upper end face of the shaft 100 is The upper support 3f is inserted, and the lower support 3e is inserted into a hole provided on the lower end surface of the shaft 100. As a result, the shaft 100 is nipped and fixed from both sides in the axial direction by both support portions 3e and 3f, and is set to the movable body 3 in a state where the axial direction is the vertical direction.

  Then, the drive means 4A for forward movement is driven to move the moving body 3 forward. Specifically, as shown by solid arrows in FIG. 1, the cylinder 4c of the forward driving means 4A is driven to lower the moving pulley 4b, and the folded portion of the chain 4a is pulled downward. As a result, the mobile unit 3 moves forward, and the chain 4a of the drive means 4B for backward movement is pulled by the mobile unit 3 to move up the moving pulley 4b. Thus, the moving body 3 can be moved by twice the stroke of the cylinder 4c by lowering the moving pulley 4b with the cylinder 4c and pulling the folded portion of the chain 4a downward. As a result, since the stroke of the cylinder 4c is only half of the stroke of the movable body 3, the cylinder 4c can be miniaturized, and hence the deburring device 1 can be miniaturized.

  Thus, while the movable body 3 is advancing, the first fixed brush 5 is provided on the outer peripheral surface of the screw portion 102 of the shaft 100 set on the movable body 3 and a partial area in the circumferential direction of the lower end surface of the gear portion 103. And the second fixed brush 6 make contact (see FIG. 2). Thereby, the burrs of the circumferential direction partial region of the outer peripheral surface of the screw portion 102 and the lower end surface of the gear portion 103 are simultaneously removed.

  Further, as the movable body 3 advances, the gear 8 meshed with the rack 10 is rotated, and this rotational movement is converted into the up and down reciprocating motion of the movable brush 7 through the link mechanism 9 (see FIG. 3). . Thus, by moving the movable brush 7 up and down through the rack 10, the gear 8 and the link mechanism 9 using the movement of the movable body 3, a separate drive means for the movable brush 7 becomes unnecessary. Cost reduction and miniaturization of the deburring apparatus 1 are achieved. Then, by bringing the movable brush 7 into contact with the spline portion 101 while reciprocating the movable brush 7 in the axial direction, the movable brush 7 slides along the extending direction of the spline portion 101, so that the burr generated in the spline portion 101 can be assured. Can be removed.

  Then, when the moving body 3 reaches the front end, the moving body 3 is temporarily stopped. Thus, when the movable body 3 stops at the front end (in detail, just before stopping), the intermittent rotation mechanism 20 rotates the shaft 100 to one side by a predetermined angle. At this time, the movable brush 7 is stopped at the upper end or the lower end and is separated from the spline portion 101 of the shaft 100. As described above, by rotating the shaft 100 by a predetermined angle while the movable brush 7 is not in contact with the spline portion 101 of the shaft 100, the shaft 100 can be rotated smoothly, and damage to the movable brush 7 is caused. Can be prevented.

  Specifically, the movable body 3 moves in the direction of arrow P in FIG. 4, and the contact portion 22a of the rotary member 22 of the intermittent rotation mechanism 20 contacts the locking member 2b (see the chain line) provided on the frame 2. When in contact, the rotating member 22 rotates in the forward direction (the direction of the arrow Q) integrally with the gear member 23. At this time, the concave portion 23a of the gear member 23 rotates while being engaged with the projection 24a1 of the first link 24a of the parallel link mechanism 24, so that the pair of first links 24a resists the biasing force of the tension spring 27. It can be spread out. Then, when the projection 24a1 of the first link 24a is removed from the recess 23a of the gear member 23, the pair of first links 24a is pulled by the tension spring 27 and the projection 24a1 of the first link 24a is next to the gear member 23. It fits in the recessed part 23a. As a result, the gear member 23, the lower support 3e, and the shaft 100 supported thereby rotate by one pitch of the recess 23a.

  Next, as shown by a dotted arrow in FIG. 1, the drive means 4B for retraction is driven to retract the movable body 3. At this time, the fixed brushes 5 and 6 are brought into contact with the screw portion 102 and the gear portion 103 of the shaft 100 to remove burrs of the screw portion 102 and the gear portion 103, and reciprocate the movable brush 7 up and down. The burrs of the spline section 101 are removed by contacting the spline section 101. In addition, since the specific operation | movement at the time of reverse is the same as the operation | movement at the time of advance, detailed description is abbreviate | omitted.

  While the movable body 3 is moving forward or backward, the parallel link 24 of the intermittent rotation mechanism 20 is pulled by the tension spring 27, and the pair of first links 24a is closed, and the projection 24a1 of the first link 24a is a gear member Since the gear 23 is fitted in the recess 23a, the rotation of the gear member 23, that is, the rotation of the shaft 100 is restricted. If the frame 2 is provided with a rotation restricting portion (not shown) which contacts the first link 24a of the intermittent rotation mechanism 20 of the moving body 3 in motion from the outside in the width direction, a pair of It is possible to reliably prevent the situation in which the first link 24 a spreads and the gear member 23 and the shaft 100 rotate.

  By repeating the above, while the movable body 3 reciprocates in the front-rear direction, removal of burrs of the spline portion 101, the screw portion 102, and the gear portion 103 is performed. Reciprocation of the movable body 3 is continued until at least the intermittent rotation mechanism 20 rotates the shaft 100 once. As described above, burrs in the entire circumferential direction of the spline portion 101, the screw portion 102, and the gear portion 103 of the shaft 100 are removed.

  The present invention is not limited to the above embodiment. Hereinafter, other embodiments of the present invention will be described, but the description of the same points as the above embodiments will be omitted.

  In the embodiment shown in FIG. 5, a loop chain 11 is provided as a rotational drive unit for rotating the gear 8 provided on the moving body 3. The loop chain 11 is wound around a plurality of fixed pulleys 12 provided on the frame 2. In the illustrated example, the loop chain 11 is wound around a plurality of constant pulleys 12 (in the illustrated example, four constant pulleys 12 separated in the front-rear direction and the vertical direction) separated in the front-rear direction. As a result, the loop chain 11 is provided with a pair of horizontal areas 11a and 11b separated in the vertical direction. A part of one horizontal area (upper horizontal area 11 a in the illustrated example) of the loop chain 11 is fixed to the moving body 3. The other horizontal area (the lower horizontal area 11 b in the illustrated example) of the loop chain 11 meshes with the gear 8 provided on the moving body 3. Thus, for example, when the movable body 3 moves in the arrow A1 direction, the upper horizontal region 11a of the loop chain 11 moves in the same direction (see arrow A2), and along with this, the lower horizontal region 11b of the loop chain 11 Move in the opposite direction to the upper horizontal area 11a (see arrow A3). As a result, the gear 8 engaged with the lower horizontal area 11 b of the loop chain 11 is rotated, and the movable brush 7 reciprocates up and down via the link mechanism 9.

  As described above, by driving the gear 8 with the loop chain 11 circulating along with the movement of the movable body 3, the movement amount of the lower horizontal region 11b of the loop chain 11 in addition to the movement amount of the movable body 3 The gear 8 rotates by the amount of. Therefore, compared with the case where the gear 8 is rotated by the rack 10 as in the above embodiment, the number of rotations of the gear 8 can be doubled, so the frequency of the movable brush 7 is doubled. It is possible to more reliably remove the burrs 101.

  Moreover, although the case where two shafts 100 were set to the mobile body 3 was shown in the above embodiment, it is good also as a structure which sets only one shaft or three or more shafts not only to this but to a mobile body. Moreover, the kind of shaft which deburs with the deburring apparatus of this invention is not restricted above. For example, the shaft may be provided with only splines and threads, or only splines and gears. Alternatively, the shaft may be provided with gear portions (spur gears) as a plurality of axial grooves in contact with the movable brush.
