Description

  The present invention relates to a deburring device that removes burrs formed in an axial direction from both side surfaces of a disk-shaped workpiece.

(First prior art)
For example, when chamfering is applied to the tooth tip of a gear with a brazing cutter, burrs are formed over the side edge of the gear. The presence of such burrs is not desirable, and it is desirable to remove them immediately, and various deburring devices have been proposed.

  The conventional deburring device 100 shown in FIG. 6 is supported by the center chucks B1 and B2 so as to be rotatable around the axis, and approaches the gear W rotated by the brazing cutter K in a direction perpendicular to the axis. A rotating table having a slide table 101 that is spaced apart, extends in parallel along the axis C of the gear W on the upper surface of the slide table 101, and both ends of which are rotatably supported by a rotation support member 102 such as a bearing. 103 and a disc-shaped round tool 110 that is rotatably fitted integrally with the rotary shaft 103 and supported so as to be movable in the axial direction.

  The round tool 110 has a first disk portion 111 having a facing surface 111a facing one side surface of the gear W, and a second disk portion 112 having a facing surface 112a facing the other side surface of the gear W. In the first disk portion 111 and the second disk portion 112, work insertion portions 111b and 112b are formed by chamfering part of the outer peripheral edge of the opposing surfaces 111a and 112a.

  And between the 1st spring receiving part 104 fixed to the rotating shaft 103, and the 1st disk part 111, the 1st urging means 105 which urges | biases the 1st disk part 111 toward the 2nd disk part 112 side. Is interposed between the second spring receiving portion 106 and the second disc portion 112 fixed to the rotation shaft 103, and the second energizing portion urges the second disc portion 112 toward the first disc portion 111 side. Means 107 are interposed. Then, the first disc is arranged so that the workpiece insertion portions 111b and 112b can be arranged at positions facing the gear W by engaging the positioning pins 108a with the engaging holes 111c provided in the outer peripheral surface of the first disc portion 111. A positioning cylinder 108 for positioning the rotation stop positions of the part 111 and the second disk part 112 is provided.

  According to the conventional deburring device 100 having the above-described configuration, the slide table 101 is moved in the direction approaching the gear W while the workpiece insertion portions 111b and 112b are positioned at the predetermined rotation stop positions by the positioning cylinder 108. The gear W is inserted between the first disc portion 111 and the second disc portion 112 from the workpiece insertion portions 111b and 112b, one side surface of the gear W is pressed by the facing surface 111a of the first disc portion 111, and the other side of the gear is After the side surface is pressed by the opposing surface 112a of the second disk portion 112, the engagement of the positioning cylinder 108 with the engagement hole 111c is released.

  Then, the tooth tip is chamfered while the gear W is rotated by the rotational drive of the brazing cutter K. Thereby, the round bite 110 is rotated in accordance with the rotation of the gear W, and burrs formed on both side surfaces of the gear W by the edges of the opposing surfaces 111a and 112a are scraped off and removed.

  Then, after a predetermined time has elapsed since the rotational driving of the brazing cutter K is started, the positioning pin 108a is protruded by the positioning cylinder 108 and pressed against the outer peripheral surface of the first disk portion 111, and the first The first disk portion 111 is engaged with the engagement hole 111c by the rotation of the disc portion 111 and the workpiece insertion portions 111b and 112b are arranged at positions facing the gear W, and then the slide table 101 is moved away from the gear W, The gear W is extracted from between the first disk part 111 and the second disk part 112.

(Second prior art)
A deburring device that deburrs a side edge by rotating a cylindrical workpiece such as a gear around an axis by a rotating means and pressing a cutting blade against the side edge of the rotating workpiece with a predetermined pressing force. It has been proposed (see, for example, Patent Document 1).

(Third prior art)
As a deburring device that removes burrs formed in the axial direction from both side surfaces of a disk-shaped workpiece, a groove into which the end of the workpiece is continuously pushed in the circumferential direction is recessed in the outer circumferential surface of the roller, There has been proposed a deburring device that removes burrs at the opening edge of the groove by rotating the work and sequentially pushing the end of the work into the groove of the roller (see, for example, Patent Document 2).

  Further, a floating ring having a predetermined outer diameter is loosely fitted and held in the groove of the roller, and the floating ring is pushed and moved by pushing the end of the workpiece, so that a part of the floating ring is pushed in and the axial center. A deburring device with a mechanism that scrapes off the burrs in the roller grooves by scraping them out of the grooves with a floating ring by rotating the work in the state of protruding in the opposite direction through Has been proposed (see, for example, Patent Document 3).

JP-A-5-57503 Japanese Patent Laid-Open No. 7-237021 JP-A-8-72846

  However, in the case of the first prior art, since the workpiece insertion portions 111b and 112b are formed on a part of the outer peripheral edge of the opposing surfaces 111a and 112a, the positioning pin 108a is pressed against the first disc portion 111 and rotated. When the workpiece insertion portions 111b and 112b are moved to positions where the gear W is pressed when the stop position is positioned, the pressing force of the opposing surfaces 111a and 112a to the gear W is drastically reduced. The first biasing means may prevent slippage between the gear W and the round bit 110 because slippage may occur between the round bite 110 and the rotation stop may not be performed and the operation cycle may stop. If the urging force of 105 and the second urging means 107 is increased, there is a risk that not only the burr but also the outer peripheral surface of the gear W will be scraped. In addition, after the deburring operation, a step of positioning the workpiece insertion portions 111b and 112b at a predetermined rotation stop position by the positioning cylinder 108 is required, and this process has a problem that the cycle time is long.

  Further, since the first disk portion 111 and the second disk portion 112 are urged by two mutually independent urging means, that is, the first urging means 105 and the second urging means 107, a uniform pressing force can be obtained. In particular, when the position of the side surface of the gear W is displaced in the axial direction, the pressing force on one side surface of the gear W increases and the pressing force on the other side surface decreases. There may be a difference in deburring accuracy between both side surfaces. Further, when adjusting the pressing force to the gear W, it is necessary to remove the rotary shaft 103 from the slide table 101 and disassemble the whole. Therefore, it is difficult to adjust the cutting amount (deburring degree), and there is a problem that the adjustment work takes time.

  In addition, the first disk portion 111 and the second disk portion 112 are supported so as to be rotatable integrally with the rotation shaft 103 by inserting the rotation shaft 103 into through holes formed through the respective centers. The length of each through hole in the axial direction is only the width of the first disk portion 111 and the width of the second disk portion 112, and the length in the axial direction is shorter than the radial distance. There is a possibility that it is difficult to ensure a smooth operation in the axial direction due to the fall of the portion 111 and the second disk portion 112. In particular, since the setting of the gear W between the first disk portion 111 and the second disk portion 112 is performed by insertion from the workpiece insertion portions 111b and 112b, the gear W is liable to fall down, and the gear W is formed on both side surfaces. There is also a risk of insertion flaws.

  The second prior art deburr one side edge of the workpiece, and cannot deburr both side edges at once. Therefore, the cycle time is long and it is difficult to increase the number of production.

  In the case of the third prior art, both side edges can be deburred at one time, but it cannot cope with a change in the thickness of the work and is not versatile. Therefore, it is necessary to prepare a roller with a corresponding groove width for each workpiece thickness, it takes time to set up rollers, and it is necessary to secure a storage place for unused rollers. Have a problem.

  In view of these problems, the present invention has been made to solve the problems of the prior art, and its purpose is to cope with workpieces having various sizes, and to provide stable deburring accuracy in a short cycle time. The object is to provide a deburring device that can be secured.

The cylinder rod 41b protrudes from the cylinder body 41a, and the open / close pin 42 enters between the first large diameter portion 13 and the second large diameter portion 23.

  The open / close pin 42 presses the first inclined surface 14a of the first small-diameter portion 14 and the second inclined surface 24a of the second small-diameter portion 24 so that the tip portion is between the first opposing surface portion 14b and the second opposing surface portion 24b. The first deburring surface portion 13c and the second deburring surface portion are inserted and moved by expanding and moving the first disk portion 12 and the second disk portion 22 in a direction away from each other against the biasing force of the biasing spring 33. The separation distance X2 with respect to 23c is set to a sufficiently large separation distance X2 facing the both side faces w1, w2 of the gear W with a predetermined gap from the separation distance X1 narrower than between the both side faces w1, w2 of the gear W. To.

  Then, a control signal is output from the control unit 50 to the feed unit 3, the movable table 3 a is moved forward based on the control signal, and the slide table 4 is disposed at a preset stop position. As a result, as shown in FIG. 4, the gear W is interposed between the first large diameter portion 13 and the second large diameter portion 23, and the first deburring surface portion 13 c and the second deburring surface portion 23 c are It arrange | positions in the position which each opposes both side surfaces w1 and w2.

  When the gear W is interposed between the first large diameter portion 13 and the second large diameter portion 23 by the movement control of the feed unit 3, the cylinder rod 41b of the cylinder mechanism 41 is moved to the cylinder body by the switching control of the electromagnetic valve 53. The tip end portion of the opening / closing pin 42 is removed from between the first facing surface portion 14b of the first small diameter portion 14 and the second facing surface portion 24b of the second small diameter portion 24.

  When the open / close pin 42 is removed from between the first small diameter portion 14 and the second small diameter portion 24, the first disc portion 11 and the second deburring of the first deburring member 10 are urged by the urging force of the urging spring 33. The second disk portion 22 of the member 20 moves in a direction approaching each other. Thus, the gear W is sandwiched between the first large-diameter portion 13 and the second large-diameter portion 23, and the first deburring surface portion 13c and the second deburring surface portion 23c are provided on both side surfaces w1 and w2 of the gear W.

Therefore, the first deburring surface portion 13c and the second deburring surface portion 23c can be pressed against the both side surfaces w1, w2 of the gear W with the same pressing force.

  When the gear W is sandwiched between the first large diameter portion 13 and the second large diameter portion 23, the brazing cutter K is rotationally driven by a rotational drive means (not shown), and the teeth W are chamfered while rotating the gear W. . And by this chamfering process, the burr | flash is formed in the both sides | surfaces w1 and w2 of the gearwheel W in the axial direction.

  When the gear W is rotated by the brazing cutter K, the first deburring member 10 and the second deburring member 20 are also rotated with the gear W. Therefore, the both side surfaces w1, w2 of the gear W are formed to project on the both side surfaces w1, w2 of the gear W at a position in front of the rotation direction with respect to the range where the first deburring surface portion 13c and the second deburring surface portion 23c are in contact with each other. The first deburring surface portion of the first deburring surface portion 13c and the second deburring surface portion 23c of the first deburring member 10 and the second deburring member 20 that rotate along with the gear W is provided. The edge portion 13c and the edge portion of the second deburring surface portion 23c are scraped off from the radially outer side toward the center and removed.

  If it is determined that chamfering processing and deburring processing have been performed over the entire circumference of the gear W after a predetermined time has elapsed since the rotational driving of the brazing cutter K is started, the rotational driving of the brazing cutter K is performed. In addition to stopping, switching control of the electromagnetic valve 53 is performed, the cylinder rod 41b is protruded from the cylinder body 41a of the cylinder mechanism 41, and the opening / closing pin 42 is inserted between the first small diameter portion 14 and the second small diameter portion 24, The 1 disc part 12 and the 2nd disc part 22 are pushed and moved in the direction away from each other against the urging force of the urging spring 33, and the separation distance between the first deburring surface part 13c and the second deburring surface part 23c is moved. X is X2, and the first deburring surface portion 13c and the second deburring surface portion 23c are separated from both side surfaces w1, w2 of the gear W, and are arranged at positions facing each other with a predetermined gap.
