Description

  The present invention relates to a centrifugal barrel polishing machine.

  In Patent Document 1, a turret that is rotated around a sun axis by a revolving motor, a plurality of barrel tanks that are rotatably provided at an eccentric position of the turret, and a rotation motor that is integrally rotated with the sun axis. There is disclosed a centrifugal barrel polishing machine that includes a solar rotor and a rotation reduction mechanism that reduces and transmits the rotational force of the solar rotor to a barrel tank and rotates the barrel tank in a planetary manner to perform barrel polishing. This centrifugal barrel polisher can rotate the turret and the barrel tank individually with the dedicated motors for revolution and rotation, so that the rotation speed of the turret and the solar rotor can be set individually. There is an advantage that the degree of freedom in setting the revolution ratio is high.

JP 2014-620 A

  In the centrifugal barrel polishing machine, generally, the revolution direction and the rotation direction of the barrel tank are opposite to each other. Therefore, the rotational driving force applied to the turret from the motor for revolution and the rotational driving force applied to the barrel tank from the motor for rotation are mutually attenuated by the other side, so that both motors are driven accordingly. Power consumption increases. In addition, when the rotation motor uses a rotation speed region that is always in regenerative operation during polishing, it is necessary to install a regenerative converter in the inverter of the rotation motor, which increases the cost.

  As a countermeasure for this, while omitting the motor for rotation, the sun shaft and the solar rotor are fixed to be non-rotatable, and the solar vessel and the barrel vessel are rotated relative to each other by using the rotating operation of the turret, thereby decelerating the barrel vessel. A method is conceivable. In this way, since only one motor is required, the problems of power consumption and regenerative converter are solved.

  However, since the number of revolutions of the solar rotor (that is, the revolution number of the barrel tank) is limited to the same number of revolutions as the turret, when changing the revolution ratio, only the reduction ratio in the revolution reduction mechanism is changed. Must respond. Since the reduction mechanism for rotation is arranged in a narrow inter-axis range between the sun rotor and the barrel tank, it is difficult to arrange multistage gears, and there is a restriction on changing the reduction ratio.

  The present invention has been completed based on the above circumstances, and is a centrifugal barrel polishing machine that has a high degree of freedom in setting the rotation and revolution ratio and can rotate the barrel tank planetarily with only one motor. The purpose is to provide.

The centrifugal barrel polishing machine of the present invention is
A turret rotatable around the sun axis;
A barrel tank disposed at an eccentric position of the turret and attached to the turret so as to be rotatable relative to the turret;
A solar rotor capable of rotating independently of the turret around the sun axis and capable of transmitting a rotational force to the barrel tank;
A motor,
Revolving torque transmitting means for transmitting the torque of the motor to the turret;
Rotational force transmission means for rotation for transmitting the rotational force of the motor to the solar rotor;
It is characterized in that it comprises a speed reduction mechanism provided in at least one of the rotational torque transmission means for revolution and the rotational power transmission means for rotation.

  According to this configuration, even if there is only one motor, the barrel tank can be rotated planetarily by rotating the turret and the solar rotor independently by the revolution torque transmission means and the revolution torque transmission means for rotation. it can. Further, by providing a speed reduction mechanism in at least one of the rotational torque transmission means and the rotational torque transmission means for revolution, the revolution speed and the rotational speed can be individually set and changed. The degree of freedom in setting the ratio is high.

As shown in FIGS. 3 and 4, the four pairs of planetary shafts 18 are eccentric by the same dimension radially outward from the sun shaft 15 and are arranged at an equal angular pitch of 90 ° in the circumferential direction. A barrel case (not shown) is fixed to the planetary shafts 18 forming a pair so as to integrally rotate, and a barrel tank 24 is accommodated in each barrel case so as to rotate integrally. Accordingly, the four barrel tanks 24 revolve around the sun axis 15, and each barrel tank 24 is integrated with the planetary axis 18 and integrally with the planetary axis 18, and rotates relative to the turret 17 (rotation). It has come to be able to do.

  As shown in FIG. 4, planetary sprockets 19 </ b> A and 19 </ b> B are fixed to each planetary shaft 18 on the left side so that they can rotate together coaxially. The four planetary sprockets 19A and 19B include a pair of first planetary sprockets 19A adjacent to each other at an interval of 90 ° in the circumferential direction, and a pair of second planetary sprockets 19B adjacent to each other at an interval of 90 ° in the circumferential direction. It is composed of The pair of first planetary sprockets 19 </ b> A and the pair of second planetary sprockets 19 </ b> B are disposed on opposite sides of the sun shaft 15. As shown in FIG. 1, in the left-right direction, the distance between the pair of first planetary sprockets 19A from the outer surface of the left turret 17 is shorter than the pair of second planetary sprockets 19B.

  As shown in FIG. 1, at the left end of the sun shaft 15, a first rotation drive sprocket 20 </ b> A and a second rotation drive sprocket 20 </ b> B are coaxial with the sun shaft 15 and in the left-right direction (the axis of the sun shaft 15 Direction). The both-rotation drive sprockets 20 </ b> A and 20 </ b> B can rotate together and can rotate relative to the sun shaft 15. In the left-right direction, the first rotation drive sprocket 20A is positioned so as to correspond to the first planetary sprocket 19A, and the second rotation drive sprocket 20B is positioned so as to correspond to the second planetary sprocket 19B.

  As shown in FIG. 4, an endless second chain 21 is interposed between the first rotation driving sprocket 20A and the pair of first planetary sprockets 19A through a tension sprocket 22 so as to be approximately L in side view. It is hung around to form a letter shape. Further, between the second rotation drive sprocket 20B and the pair of second planetary sprockets 19B, the endless second chain 21 has a substantially L shape in a side view through the tension sprocket 22. It is laid around.

  In the first rotation drive sprocket 20A and the second rotation drive sprocket 20B, a rotation driven sprocket 23 (a solar rotor described in claims) coaxial with the sun shaft 15 is integrated with both rotation drive sprockets 20A and 20B. It is attached so that it can rotate. The rotation driven sprocket 23 is arranged coaxially with the revolution driven gear 16, but is rotated independently of the revolution driven gear 16.

  The rotational force transmitted to the rotation driven sprocket 23 is transmitted to the pair of first planetary sprockets 19A via the first rotation driving sprocket 20A and the second chain 21, and at the same time, the second rotation driving sprocket 20B and It is transmitted to the pair of second planetary sprockets 19B via the second chain 21. The rotational force transmitted to the planetary sprockets 19A and 19B is transmitted to the four barrel tanks 24 via the planetary shaft 18, and the barrel tanks 24 rotate. Therefore, the first rotation drive sprocket 20A, the second rotation drive sprocket 20B, the second chain 21, the first planetary sprocket 19A, the second planetary sprocket 19B, and the planetary shaft 18 are transmitted to the rotation driven sprocket 23. Planetary rotational force transmitting means 25 for transmitting rotational force to the four barrel tanks 24 is configured.

  In the space below the turret 17 in the housing 10, the motor 26 is disposed in a state of being placed on the base 11. The motor 26 has a drive shaft 27 (the output shaft of the motor according to the claims) whose axis is parallel to the sun shaft 15, and is fixed to the drive shaft 27 so that the drive gear 28 rotates integrally. Has been. The motor 26 is disposed at the rear end portion (behind the sun shaft 15) of the base 11 in the front-rear direction (a direction orthogonal to the sun shaft 15 in plan view). Moreover, the motor 26 is arrange | positioned so that it may respond | correspond to the area | region on the left rather than the axial center of the sun axis 15 in the left-right direction. The drive gear 28 is disposed at a position slightly to the right of the center of the sun shaft 15 in the left-right direction.

  In the space below the turret 17 in the housing 10, a speed reduction mechanism 29 is disposed in a state of being placed on the base 11 at substantially the same height as the motor 26. As shown in FIGS. 1 and 2, the speed reduction mechanism 29 includes a rotation input shaft 30 (the input shaft of the drive mechanism described in the claims) whose axis is parallel to the sun shaft 15 and the drive shaft 27, and the axis is the sun. An output shaft 32 for rotation directed parallel to the shaft 15 and the drive shaft 27 is provided. A rotation input gear 31 is fixed to the rotation input shaft 30 so as to rotate integrally. An output sprocket 33 for rotation is fixed to the output shaft 32 for rotation so as to rotate integrally.

  The speed reduction mechanism 29 accommodates a well-known reduction gear (not shown) for reducing the rotational force input to the rotation input shaft 30 and transmitting it to the rotation output shaft 32. The speed reduction mechanism 29 is disposed at the front end of the base 11 (in front of the sun shaft 15) in the front-rear direction, and is disposed at substantially the same position as the motor 26 in the left-right direction. The rotation input gear 31 is disposed at the same position as the drive gear 28 in the left-right direction. The output sprocket 33 for rotation is disposed at the same position as the driven sprocket 23 for rotation (a position corresponding to the left end portion of the sun shaft 15). As shown in FIG. 3, an endless first chain 34 is wound around the rotation output sprocket 33 and the rotation driven sprocket 23.

  In the space below the turret 17 in the housing 10, the clutch 35 is disposed on the base 11 at substantially the same height as the motor 26 and the speed reduction mechanism 29. The clutch 35 has a revolution input shaft 36 (an input shaft of the clutch according to the claims) whose axis is parallel to the sun shaft 15 and the drive shaft 27, and an axis is parallel to the sun shaft 15 and the drive shaft 27. And an output shaft 38 for revolution. A revolution input gear 37 is fixed to the revolution input shaft 36 so as to rotate integrally. A revolution output gear 39 is fixed to the revolution output shaft 38 so as to rotate integrally.

  Inside the clutch 35, a transmission mode capable of transmitting the rotational force input to the revolution input shaft 36 to the revolution output shaft 38 and the rotational force input to the revolution input shaft 36 to the revolution output shaft 38. A transmission switching mechanism (not shown) in a known form that switches to a blocking mode that blocks transmission is housed. Therefore, the clutch 35 functions as a means for enabling the barrel tank 24 to rotate while the turret 17 is fixed. The clutch 35 is disposed in a substantially central part (substantially the same position as the sun shaft 15) of the base 11 in the front-rear direction, that is, between the motor 26 and the speed reduction mechanism 29. The clutch 35 is disposed at a position on the right side of the motor 26 and the speed reduction mechanism 29 in the left-right direction.

  The revolution input gear 37 of the clutch 35 is disposed at the same position as the drive gear 28 and the rotation input gear 31 in the left-right direction. An endless first timing belt 41 is wound around the drive gear 28, the rotation input gear 31, and the revolution input gear 37 via a tension pulley 40. As a result, the rotational force of the motor 26 is transmitted simultaneously to the rotation input shaft 30 of the speed reduction mechanism 29 and the revolution input shaft 36 of the clutch 35 via the first timing belt 41.

  The revolution output gear 39 of the clutch 35 is disposed at the same position as the revolution driven gear 16 (a position corresponding to the right end portion of the sun shaft 15). An endless second timing belt 42 is wound between the revolution output gear 39 and the revolution driven gear 16. Thereby, the rotational force of the revolution output shaft 38 of the clutch 35 is transmitted to the revolution driven gear 16 via the second timing belt 42.

  As described above, the drive shaft 27 of the motor 26, the first timing belt 41, the revolution input gear 37 of the clutch 35, the revolution input shaft 36, the transmission switching mechanism in the clutch 35, the revolution output shaft 38, the revolution output. The gear 39, the second timing belt 42, the revolving driven gear 16, and the sun shaft 15 constitute revolving rotational force transmission means 43 that transmits the rotational force of the drive shaft 27 of the motor 26 to the turret 17. Further, the drive shaft 27 of the motor 26, the first timing belt 41, the input gear 31 for rotation of the speed reduction mechanism 29, the input shaft 30 for rotation, the speed reduction gear in the speed reduction mechanism 29, the output shaft 32 for rotation, and the output sprocket 33 for rotation. The first chain 34 constitutes rotational torque transmitting means 44 for rotation that transmits the rotational force of the motor 26 to the driven sprocket 23 for rotation.

  Next, the operation of the first embodiment will be described. When the motor 26 is driven to perform polishing using the centrifugal barrel polishing machine of the first embodiment, the rotational force of the motor 26 is transmitted to the turret 17 via the revolving rotational force transmission means 43 including the clutch 35, Four barrel tanks 24 revolve around the sun axis 15. The revolution torque transmitting means 43 for revolution transmits the torque of the motor 26 to the turret 17 but does not transmit it to the driven sprocket 23 for rotation. At this time, the rotational force of the drive shaft 27 of the motor 26 is decelerated and transmitted to the revolution input shaft 36 of the clutch 35, and the rotational force of the revolution input shaft 36 is transmitted to the revolution output shaft 38 at the same rotational speed. The rotational force of the revolution output shaft 38 is decelerated and transmitted to the revolution driven gear 16, the sun shaft 15, and the turret 17.

  Further, the rotational force of the motor 26 is not limited to the turret 17 but also via the rotational torque transmitting means 44 including the speed reduction mechanism 29, so that the driven driven sprocket 23 and the first and second rotational drive sprockets 20A. , 20B. The rotation torque transmission means 44 for rotation transmits the rotation force of the motor 26 to the driven sprocket 23 for rotation but does not transmit it to the turret 17. Therefore, the driven sprocket 23 for rotation and the first and second rotation drive sprockets 20 </ b> A and 20 </ b> B rotate independently of the turret 17. The rotational force decelerated from the motor 26 and transmitted to the driven sprocket 23 for rotation is transmitted to the four barrel tanks 24 via the planetary rotational force transmission means 25.

  In the rotation torque transmission means 44 for rotation, the rotation force of the drive shaft 27 of the motor 26 is transmitted after being decelerated to the rotation input shaft 30 of the speed reduction mechanism 29, and the rotation force of the rotation input shaft 30 is transmitted through the reduction gear. As a result, the speed is reduced and transmitted to the output shaft 32 for rotation, and the rotational force of the output shaft 32 for rotation is transmitted to the driven sprocket 23 for rotation. The rotational force transmitted from the output shaft 32 for rotation to the driven sprocket 23 for rotation is increased, but since the reduction ratio in the speed reduction mechanism 29 is large, the rotation transmitted to the driven sprocket 23 for rotation. The force is decelerated as compared with the input shaft 30 for rotation.

  As an example of the reduction ratio, when the rotational speed of the motor 26 is 1800 rpm, the rotational force transmitted to the revolution input shaft 36 and the revolution output shaft 38 of the clutch 35 is applied to the revolution rotational force transmission means 43. The speed is reduced to 1000 rpm, and the rotational force transmitted to the revolving driven gear 16, the sun shaft 15 and the turret 17 is further reduced to 200 rpm. On the other hand, in the rotation torque transmission means 44 for rotation, the rotation force transmitted to the rotation input shaft 30 of the deceleration mechanism 29 is reduced to 1500 rpm, and the rotation force transmitted to the rotation output shaft 32 is reduced by the deceleration mechanism 29. The speed is reduced to 150 rpm by the gear, and the rotational force transmitted to the driven sprocket 23 for rotation is further reduced to 100 rpm. The rotational force transmitted to the rotation driven sprocket 23 is transmitted to the barrel tank 24 without being decelerated by the planetary rotational force transmission means 25. The difference between the rotational speed of the turret 17 and the rotational speed of the barrel tank 24 is the rotational rotational speed of the barrel tank 24. Therefore, the barrel tank 24 rotates at 100 rpm in a direction opposite to the revolution direction while revolving at 200 rpm.

  The centrifugal barrel polishing machine according to the first embodiment includes a turret 17 that can rotate around a sun axis 15 and four barrel tanks 24 that are arranged at an eccentric position of the turret 17 and are mounted so as to be relatively rotatable with respect to the turret 17. The barrel tank 24 is supported so as to be rotatable on a planetary plane. Then, as means for transmitting the rotational force (planetary rotational force) of rotation and revolution to the barrel tank 24, it can rotate independently of the turret 17 around the sun shaft 15 and can transmit the rotational force to the barrel tank 24. The rotation driven sprocket 23, the motor 26, the rotation torque transmitting means 43 for transmitting the rotational force of the motor 26 to the turret 17 instead of the rotation driven sprocket 23, and the torque of the motor 26 to the turret 17 Rotational force transmission means 44 for rotation transmitted to the driven sprocket 23 for rotation, and a speed reduction mechanism 29 provided in the rotational force transmission means 44 for rotation.

  As described above, in the centrifugal barrel polishing machine of the first embodiment, even if there is only one motor 26, the turret 17 and the revolving driven sprocket 23 are individually separated by the revolving rotational force transmitting means 43 and the revolving rotational force transmitting means 44. Can be rotated. In other words, the barrel tank 24 can be planetarily rotated by one motor 26. Since the speed reducing mechanism 29 is provided in the rotational torque transmission means 44 for rotation, the revolution speed and the rotation speed of the barrel tank 24 can be individually set and changed by appropriately setting the speed reduction ratio of the speed reduction mechanism 29. Can do. That is, the rotation speed of the driven sprocket 23 for rotation for rotating the barrel tank 24 is not affected by the revolution speed of the turret 17. Therefore, there is a high degree of freedom when setting the revolution ratio.

  In addition, the operator attaches / detaches the barrel tank 24 to / from the turret 17 while standing near the turret 17 (the outer surface of the housing 10). In the first embodiment, the motor 26, the speed reduction mechanism 29, and the clutch 35 are connected. In the lower part of the turret 17 (that is, in the housing 10), the turrets 17 are arranged so as to be arranged at substantially the same height. Therefore, when the worker stands near the turret 17 and attaches or detaches the barrel tank 24, the motor 26, the speed reduction mechanism 29, and the clutch 35 do not interfere with the work.

  In addition, the motor 26 requires periodic maintenance for inspection, replacement, insulation resistance measurement, and the like of the sliding parts provided inside, and the speed reduction mechanism 29 needs to be replaced when the revolution ratio is changed. It is. On the other hand, the clutch 35 is hardly required to replace parts. Therefore, in the first embodiment, the clutch 35 is disposed so as to be sandwiched between the motor 26 and the speed reduction mechanism 29 arranged in the front-rear direction perpendicular to the sun shaft 15 in plan view. That is, the motor 26 is disposed near the rear wall 14 constituting the housing 10, and the speed reduction mechanism 29 is disposed near the front wall 13 constituting the housing 10. Therefore, by providing work openings (not shown) in the front wall 13 and the rear wall 14, it is easy to perform maintenance work of the motor 26 and replacement work of the speed reduction mechanism 29.

  In the first embodiment, the clutch 35 is provided in the revolution torque transmission means 43 and the speed reduction mechanism 29 is provided in the rotation torque transmission means 44, but the drive shaft 27 of the motor 26 and the clutch 35 are One first timing belt 41 is wound between the revolution input shaft 36 and the rotation input shaft 30 of the speed reduction mechanism 29. According to this configuration, the rotational force transmission from the motor 26 to the clutch 35 and the rotational force transmission from the motor 26 to the speed reduction mechanism 29 can be performed by only one first timing belt 41. Therefore, compared with the case where the transmission of the rotational force to the clutch 35 and the transmission of the rotational force to the speed reduction mechanism 29 are performed using separate transmission members (timing belts or the like), the first embodiment requires fewer parts. It is out.

  Further, when a mass is put into the barrel tank 24 before polishing or when the mass in the barrel tank 24 is discharged after polishing, the turret 17 is rotated to move the barrel tank 24 to a position where it can be easily operated. At this time, if the barrel tank 24 rotates in a planetary manner in conjunction with the turret 17 in the same manner as at the time of polishing, even if the barrel tank 24 is moved to a position where it can be easily operated, the opening of the barrel case faces downward. Therefore, there is a concern that it is difficult to perform the operation of removing the barrel tank 24 from the barrel case. This concern is the same when the barrel tank 24 is attached to the barrel case.

  Therefore, in the first embodiment, the revolution torque transmission means 43 is provided with the clutch 35 capable of interrupting the transmission of the torque from the motor 26 to the turret 17. When the mass into the barrel tank 24 or the mass within the barrel tank 24 is discharged, if the transmission of the rotational force from the motor 26 to the turret 17 is interrupted in the clutch 35, the turret 17 rotates. The direction of the barrel tank 24 can be freely changed without interlocking. Therefore, according to the first embodiment, the barrel tank 24 can be changed to a direction suitable for work without being restricted by the rotational position of the turret 17.
