Description

  The present invention relates to a working device for stacking a ring plate provided with a plurality of external teeth in a state in which the external teeth are aligned when, for example, a wet clutch or a wet brake is assembled in an automatic transmission case. Is.

As the above-described conventional working device, the outer teeth are aligned by repeatedly applying a claw-like member called a pusher to the outer teeth of one ring plate, and then stacked on another ring plate. (For example, refer to Patent Document 1).
JP 2002-266893 A

  However, such a conventional working device needs to align the external teeth each time the ring plates are stacked, which complicates the work, resulting in a complicated device and improved working time. There is room for.

  The problem to be solved by the present invention is that in a conventional working device, when a ring plate provided with a plurality of external teeth is stacked in a state where the external teeth are aligned, the positional deviation of the external teeth is adjusted. The work is to become complicated.

The present invention is a working device for stacking a ring plate provided with a plurality of external teeth in a state where the external teeth are aligned,
A table having a columnar portion that penetrates the ring plate in a rotatable manner, and a table that can be placed in a state where the ring plates are sequentially stacked, and a base that can be moved forward and backward with respect to the ring plates stacked on the table ,
The base includes two arm members that protrude toward the ring plate and extend in the stacking direction, a connecting means that connects the arm members to the base so that the arm members are opened apart from each other, and an arm member Arm return means for generating an urging force for returning the arm member to the initial position when the arm member is isolated and opened,
The tips of the two arm members can come into contact with the ring plate by the approach of the base, and the interval between the arm members is such that when one arm member abuts against the external teeth, the other arm member The ring plate is positioned to face the tooth bottom of the ring plate.

  Examples of the connecting means of the present invention include a pin and a hinge member. The arm return means includes a torsion spring (for example, a torsion coil spring). Further, as a means for driving the base, an air cylinder can be cited.

In addition, according to the present invention, when the base is brought close to the ring plate, the tip of the two arm members presses the ring plate together with the columnar portion, so that the trace of pressing the arm member does not remain on the ring plate . It is preferable to stop the movement of the base.

  Furthermore, according to the present invention, it is preferable that a clearance is formed between the columnar part and the opening of the ring plate so that play is provided between the columnar part and the ring plate.

  According to the present invention, the ring plates can be stacked in advance by a simple operation of passing the ring plates sequentially through the columnar portions.

  Further, according to the present invention, the tips of the two arm members can come into contact with the ring plate by the approach of the base, and the interval between the arm members is such that when one arm member abuts against the external teeth. The other arm member is positioned to face the tooth bottom of the ring plate.

  Thereby, when the base is brought close to and one arm member comes into contact with the side surface of the outer teeth of the ring plate, the ring plate is rotated so as to escape outward. Following this, when the other arm member located at the tooth bottom of the ring plate contacts the tooth bottom, it moves along the tooth bottom in the opposite direction to the rotation direction of the ring plate, and then approaches as the ring plate rotates. The arm member comes into contact with the nearest external tooth.

  On the other hand, when the base is approached and one arm member comes into contact with the tip of the outer teeth of the ring plate, the arm member stays at the tip of the outer teeth and rotates so as to release the ring plate outward. In addition, there is a possibility of overcoming the tip of the external tooth, but even if the tip of the external tooth is overtaken, the other arm member located at the tooth bottom of the ring plate contacts the tooth bottom. After that, the arm member comes into contact with the nearest external tooth by moving along the tooth bottom.

  In this case, the other arm member contacts the side surface of the outer tooth of the ring plate, and then the ring plate is rotated so as to escape outward. Then, the one arm member that has overcome the outer tooth rotates the ring plate. As a result, the arm member that has been approaching comes into contact with an external tooth different from the immediate external tooth.

  That is, the distance between the two arm members is set to a dimension that follows the contact of the one arm member with the external tooth and the other arm member is positioned at the tooth bottom of the ring plate. After the arm member hits the side surface of the external tooth and rotates the ring plate, the other arm member hits the side surface of the other external tooth, so that the external teeth of the stacked ring plates are not aligned. Positioning can be performed simply by bringing the two arm members into contact with each other. Since this phenomenon occurs for each of the stacked ring plates, as a result, the external teeth of the ring plates simply stacked on the table are aligned with each other.

  Therefore, according to the present invention, when a ring plate provided with a plurality of external teeth is stacked in a state where the external teeth are aligned, the positional deviation of the external teeth can be simply made by contacting the two arm members. Can be adjusted by simple work.

  Further, according to the present invention, the work for stacking the ring plate provided with a plurality of external teeth in a state where the external teeth are aligned is simplified, thereby simplifying the apparatus and shortening the operation time. Can be achieved.

  Moreover, since the two arm members are each connected to the base so as to open outward with respect to the base, even if the arm member is pressed against the tooth bottom of the ring plate, the arm member remains in the teeth of the ring plate. It can escape to an external tooth along the curved surface shape which comprises a bottom. For this reason, the trace (indentation) which pressed the arm member on the external tooth and the tooth bottom of the ring plate hardly remains. For this reason, the incidence rate of defective products due to the appearance shape can be kept low, and the productivity is excellent.

  In addition, since the urging force for returning to the initial position is applied to the arm member, after adjusting the positional deviation of the external teeth between the ring plates, the base is moved away from the stacked ring plates. Then, the arm member returns to the initial position. In other words, since an operation for returning the arm member is not required, it is effective when the work for stacking the ring plate provided with a plurality of external teeth in a state where the external teeth are aligned is continuously performed. It is.

  Moreover, according to this invention, the space | interval of two arm members can be variously set according to the dimension which prescribes | regulates external teeth, such as a toothpick of a ring plate, and a tooth base.

Further, in the present invention, when the base is brought close to the ring plate, the tip of the two arm members presses the ring plate together with the columnar portion so that the trace of pressing the arm member does not remain on the ring plate. If the movement of the base is stopped, the traces (striking marks) of pressing the arm member are less likely to remain. That is, since the incidence of defective products due to the appearance shape can be further reduced, productivity can be further improved.

  Furthermore, in the present invention, if a clearance is formed between the columnar part and the opening of the ring plate so that play is provided between the columnar part and the ring plate, the arm member is caught on the outer teeth of the ring plate. Even in the case of interference, the interference can be canceled by escaping the ring plate, so that the phase shift of the external teeth between the ring plates can be reliably adjusted.

  Hereinafter, a working device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an embodiment of the present invention for alternately stacking a driven plate (ring plate) 20 provided with external teeth 21 and a drive plate 30 when a drum brake is assembled in an automatic transmission case. It is a perspective view which shows an apparatus typically. FIG. 2 is a perspective view schematically showing a main part of the working device in the same form as before the outer teeth 21 of the stacked driven plates 20 are aligned.

In FIG. 1, reference numeral 1 denotes a table on which a driven plate 20 and a drive plate 30 can be alternately placed. The table 1 can be moved forward and backward while being appropriately positioned along the direction of the arrow d ₁ by using existing means (for example, a motor and a linear motion mechanism).

The upper surface of the table 1, by cutting out both sides of the moving direction d ₁ of the table 1, and the flat surface 11a raised between its mutually, and notch surface 11b that sandwich the flat surface 11a is formed. Thereby, the flat surface 11a of the present embodiment substantially functions as a mounting surface on which the driven plate 20 and the drive plate 30 can be mounted in a stacked state.

  In addition, a cylindrical columnar portion 12 stands integrally from the flat surface 11a. The outer diameter of the columnar portion 12 is set smaller than the inner diameter dimension that forms the opening A of the driven plate 20 and the innermost diameter dimension of the opening B of the drive plate 30. Therefore, the driven plate 20 and the drive plate 30 can be stacked on the table 1 by passing the columnar portion 12 through the opening A of the driven plate 20 and the opening B of the drive plate 30.

  Reference numeral 100a denotes means for supplying the driven plate 20 onto the table 1 (hereinafter referred to as “first plate supply means”). The first plate supply means 100a includes a stocker 101a in which a plurality of driven plates 20 are stacked and stored in advance, and a slide body 102a that can be opened and closed by sliding a lower end opening of the stocker 101a. A recess for placing the driven plate 20 is formed on the upper surface of the slide body 102a. Further, a stopper device 103a including a shaft-like stopper 103s that can be moved up and down is provided in front of the stocker 101a.

  Reference numeral 100b denotes means for supplying the drive plate 30 onto the table 1 (hereinafter referred to as “second plate supply means”). The second plate supply means 100b also includes a stocker 101b in which a plurality of drive plates 30 are stacked and stored in advance, and a slide body 102b that opens and closes an opening formed at the lower end of the stocker 101b. A recess for placing the drive plate 30 is also formed on the upper surface of the slide body 102b.

  A stopper device 103b including a shaft-like stopper 103s that can be moved up and down is also provided in front of the stocker 101b. As a result, after the table 1 is moved to the front of the first plate supply means 100b and temporarily stopped, when the slide body 102b is pushed out from the stocker 101b onto the table 1, as shown in the stocker 101b, the driven plate 20 is columnar. It is sent to just below part 12. This configuration is the same for the first plate supply means 100a.

  After the stopper 103s is lowered from the stopper device 103a, the driven plate 20 is dropped from the slide body 102a by pulling back the slide body 102a. As a result, the driven plate 20 can be placed on the table 1 through the columnar portion 12. The drive plate 30 can also be placed on the table 1 by moving the table 1 to the front of the second plate supply means 100b and temporarily stopping it.

  That is, if the desired number of first plate supplying means 100a and the second plate supplying means 100b are alternately arranged and sequentially operated together with the table 1, a desired number of driven plates 20 and drives are automatically placed on the table 1. Plates 30 can be stacked alternately.

  Reference numeral 2 denotes a base that can approach and move away from the plurality of driven plates 20 and drive plates 30 stacked on the table 1.

  In this embodiment, an air cylinder 120 as shown is used as means for moving the base 2 back and forth. Reference numeral 121 denotes a piston rod of the air cylinder 120, and the piston rod 121 is connected to the base 2. Thereby, the base 2 can approach and move away from the plurality of stacked driven plates 20 and drive plates 30 with air pressure.

  As in this embodiment, if a pneumatic device such as an air cylinder is used as a means for moving the base 2 back and forth, it is effective to suppress consumption of energy resources, but means for moving the base 2 back and forth. However, the present invention is not limited to this, and various modifications such as a hydraulic type and a motor drive type can be made.

  Here, FIGS. 3A and 3B are an enlarged plan view and a perspective view of the base 2, respectively.

  In FIG. 3, reference numeral 3 denotes an arm member that protrudes toward the stacked driven plate 20 and drive plate 30. The arm member 3 includes an arm fixing portion 31 fixed to the side surface of the base 2 and an arm main body 32 connected to the arm fixing portion 31 so as to open outward with respect to the base 2 via the arm fixing portion 31. It consists of.

  As shown in FIG. 2 and FIG. 3B, the arm body 32 has a plate shape extending in the stacking direction (hereinafter referred to as “plate center axis”) O of the driven plate 20 and the drive plate 30.

  Further, when the arm main body 32 is configured to open outward with respect to the base 2, in this embodiment, a convex portion 31 p is formed in front of the arm fixing portion 31, and the convex portion is disposed behind the arm main body 32. A configuration is adopted in which a recess 32n where 31p is combined is formed and the arm main body 32 is pivotably coupled to the arm fixing portion 31 using a hinge pin as the coupling means 4. However, as the connecting means 4, a hinge member may be adopted instead of the hinge pin.

  Reference numeral 5 is an arm return means for returning the arm member 3 opened outward to the initial position. In this embodiment, a torsion coil spring is used as the arm return means 5.

  One end 51 of the arm return means 5 extends to the outer surface of the arm fixing portion 31 and is fixed to the arm fixing portion 31. The other end 52 of the arm return means 5 extends to the outer surface of the arm body 32 and is fixed to the arm body 32. Thus, the arm return means 5 generates a biasing force for returning the arm member 3 to the initial position when the arm member 3 opens outward. Note that a torsion bar may be employed as the arm return means 5.

  The feature of the present invention is that the tips e of the two arm members 3 can come into contact with the driven plate 20 by the approach of the base 2, and the distance L between the arm members 3 is such that one arm member 3 </ b> L has an external tooth. The other arm member 3 </ b> R is in a position facing the tooth bottom 22 of the driven plate 20 when it abuts against 21.

  For this reason, there are two patterns shown in FIGS. 4 and 5 in aligning the driven plate 20 by operating the apparatus according to the present invention.

Here, FIGS. 4A and 4B show that, of the two arm members 3, the tip e of one arm member 3L is in contact with the side surface 21Ls of the external teeth 21L, thereby aligning the external teeth 21. It is a top view which shows typically the 1st pattern performed. In the drawing, only one of the stacked driven plates 20 is exemplarily shown. Further, in the following description, in order to clarify the relative relationship between the external tooth 21 and the tooth bottom 22, the arm member 3, the external tooth 21, the side surface 21S of the external tooth 21 and a part of the tooth bottom 22 are exemplified. code 3L, together indicated by 21L and 21S _L, the right side of the drawing of the arm member 3, outer teeth 21, exemplarily code 3R some aspects 21S and the tooth bottom 22 of the outer teeth 21, indicated by 21R and 21S _R in.

  In the first pattern, as shown in FIG. 4 (a), the two arm members 3 have an interval L between the tips e such that one arm member 3L contacts the external teeth 21L and at the same time the other arm The member 3 </ b> R is set to a dimension positioned at the tooth bottom 22 </ b> L of the driven plate 20.

  Further, a clearance C is formed between the columnar portion 12 and the opening A of the driven plate 20, as shown in FIG. That is, the driven plate 20 is stacked on the table 1 with play between the columnar portions 12.

As shown in FIG. 4A, the distance L between the two arm members 3L and 3R is made to follow the one arm member 3L coming into contact with the external teeth 21L, and the other arm member 3R is engaged with the teeth of the driven plate 20. Since the dimension is set at the bottom surface 22L, for example, when the base 2 is brought close and one arm member 3L comes into contact with the side surface 21S _L of the external tooth 21L of the driven plate 20, the arm member 3L is connected. The driven plate 20 is rotated around the plate center axis O (clockwise in the figure) as indicated by an arrow r ₁ while opening outward from the means 4 as a base point.

Accordingly, the external teeth 21R leading to the tooth base 22R of the driven plate 20 also, as shown by the arrow r _1, for rotation, the external teeth 21R is evade the tip e of the arm member 3R, the arm member 3R the tip e, as shown in FIG. 4 (b), in contact with the tooth bottom 22R 'that has been newly close with the rotation of the driven plate 20, as shown the driven plate 20 in the arrow r ₂ (FIG. Then, it contacts with the side surface 21S _R ′ of the external tooth 21R ′ while opening outward with the connecting means 4 as the base point so as to rotate.

  Thereby, even if the driven plate 20 passes through the columnar portion 12 without aligning the external teeth 21R, the external teeth 21R are always positioned at a constant phase by the two arm members 3L and 3R. Will be matched.

In contrast, FIG. 5 (a), (b), of the two arm members 3, that the tip e of one arm member 3L is in contact with the tip 21E _L of the external teeth 21L, the position of the external teeth 21 It is a top view which shows typically the 2nd pattern with which alignment is performed. Note that only one of the stacked driven plates 20 is also exemplarily shown in the drawing.

In this case, when the base 2 is approached and one arm member 3L comes into contact with the tip 21E _L of the external tooth 21L of the driven plate 20, the arm member 3L is driven while opening outward from the connecting means 4 as a base point. (in the figure, clockwise) direction shown plate 20 in the arrow r ₁ while escaping to, over the tip 21E _L of the external teeth 21L, the proximity of the base 2 between the arm member 3L escapes, the tooth bottom of the driven plate 20 the other arm member 3R is being in contact with the tooth bottom 22R located 22R, (in the figure, counter-clockwise) as the driven plate 20 is shown by an arrow r ₂ so as to rotate, to the tooth bottom 22R It moves while opening the connection means 4 along the base point. Therefore, the tip e of the arm member 3R becomes into contact with the side surface 21S _R of the most recent external teeth 21R to the arm member 3R, rotates the driven plate 20 in the arrow r ₂ direction.

Accordingly, the tip e of one arm member 3L that has passed over the external tooth 21L has a side surface 21S _L of the external tooth 21L ′ that has newly approached as the driven plate 20 rotates, as shown in FIG. 'Contact.

  Thereby, even if the driven plate 20 passes through the columnar portion 12 without aligning the external teeth 21R, the external teeth 21R are always positioned at a constant phase by the two arm members 3L and 3R. Will be matched.

  In other words, the distance L between the two arm members 3L and 3R is such that the other arm member 3R is positioned on the tooth bottom 22L of the driven plate 20 following the contact of the one arm member 3L with the external teeth 21L. By setting, after one arm member 3 hits the side surface 21S of the external tooth 21 and rotated the driven plate 20, the other arm member 3 hit the side surface 21S of the other external tooth 21 and was stacked. Even if the external teeth 21 of the driven plate 20 are not aligned, they can be aligned simply by bringing the two arm members 3L and 3R into contact. Since this phenomenon occurs for each of the stacked driven plates 20, as a result, the external teeth 21 of the driven plate 20 simply stacked on the table 1 are aligned with each other.

In both the first pattern and the second pattern, for example, when the base 2 approaches the driven plate 20 by adjusting the stroke of the air cylinder 120, the tips e of the two arm members 3L or 3R are driven. It is preferable to stop the movement of the base 2 by pressing the plate 20 together with the columnar portion 12 so that the trace of pressing the arm member 3L or 3R does not remain on the driven plate 20 . In this case, it is difficult to leave traces (striking marks) of pressing the arm member 3L or 3R. That is, since the incidence of defective products due to the appearance shape can be further reduced, productivity can be further improved.

In both the first pattern and the second pattern, when the two arm members 3L and 3R are in contact with the driven plate 20 and the external teeth 21 are aligned, the opening angle θ is about θ ₁ = 120 degrees. It has become.

  6 (a) and 6 (b) are perspective views schematically showing a transfer device 130 for further transferring the driven plate 20 and the drive plate 30 stacked in a state where the external teeth 21 are aligned, and FIG. It is a perspective view which expands and shows a principal part typically.

The transfer device 130 has a main body 131 that can move up and down along the vertical axis direction d ₄ and can move horizontally along the horizontal axis direction d _{6. The} outer teeth 21 are aligned with the main body 131. Two sandwiching members 132 for sandwiching the driven plate 20 and the drive plate 30 (hereinafter referred to as “laminated cylindrical body B _L ”) stacked on each other are provided.

Two clamping members 132 are each cooperate, it is possible to tighten the stack cylinder B _L in the direction shown by the arrow d _5. For this reason, as shown in FIG. 5 (b), each of the holding members 132 is caught by the protrusion L _p (the protrusion formed by aligning the external teeth 21) of the laminated cylindrical body _BL . a pawl member 133 to suppress the rotation of the laminated cylinder B _L, intrudes into the gap formed between the cutout surface 11b of the lower end and the table 1 of the laminated cylinder B _L, the laminated cylinder B _L, underlying And a support member 134 that is supported from the side.

Transfer device 130, after the stack cylinder B _L in table 1 is shaped, the two clamping members 132 in an open state than the outermost diameter of the laminated cylinder B _L, toward the laminated cylinder B _L The support member 134 stops at a position where the support member 134 can enter the gap between the lower end of the laminated cylindrical body _BL and the notch surface 11b of the table 1.

After stopping the descent of the transfer device 130, the two clamping members 132 by moving in the direction d _5, without shifting the phase of the external teeth 21 of the driven plate 20 of the projection L _p, The lower end of the laminated cylindrical body _BL is supported.

After holding the laminated cylinder B _L is a transfer device 130 again raises along the arrow d _4. When the transfer device 130 reaches a position higher than the belt conveyor 110, the ascent is stopped. After stopping the rise of the transfer device 130, the laminated cylinder B _L moves in parallel along the transfer device 130 until positioned on the belt conveyor 110 in the arrow d _6. When stacked cylinder B _L is positioned on the belt conveyor 110, after stopping the horizontal movement of the transfer device 130, by opening the clamping member 132 in the direction d ₅ and opposite, belt conveyor 110 a layered cylindrical body B _L Take it down. Then, if the running belt conveyor 110, while the laminated cylinder B _L multiple ridges L _p is shaped, it is possible to feed the laminated cylinder B _L to a predetermined working position.

  According to the present invention, the driven plates 20 can be alternately stacked with the drive plates 30 in advance by a simple operation of passing the driven plates 20 sequentially through the columnar portions 12.

  Further, according to the present invention, the tips e of the two arm members 3L and 3R can come into contact with the driven plate 20 by the approach of the base 2, and the distance L between them is such that one arm member 3L has an external tooth. When the second arm member 3L faces the tooth bottom 22 of the driven plate 20 when abutting against the tooth 21, the one arm member 3 hits the side surface 21S of the outer tooth 21 and rotates the driven plate 20 Then, the other arm member 3 hits the side surface 21S of the other external tooth 21, so that even if the external teeth 21 of the stacked driven plates 20 are not aligned, the two arm members 3L and Positioning can be performed simply by bringing 3R into contact. Since this phenomenon occurs for each of the stacked driven plates 20, as a result, the external teeth 21 of the driven plates 20 simply stacked on the table 1 are aligned with each other.

  Therefore, according to the present invention, when the driven plate 20 provided with the plurality of external teeth 21 is stacked in a state in which the external teeth 21 are aligned, the positional deviation of the external teeth 21 is reduced by the two arm members 3L and 3L. Adjustment can be performed with a simple operation of bringing 3R into contact.

  Further, according to the present invention, the operation for stacking the driven plate 20 in a state where the external teeth 21 are aligned is simplified, so that the apparatus can be simplified and the working time can be shortened.

  In addition, since the two arm members 3L and 3R are connected to the base 2 so as to open outward with respect to the base 2, the arm members 3L and 3R can be pressed against the tooth bottom 22 of the driven plate 20. The arm member 3 </ b> L or 3 </ b> R can escape to the external teeth 21 along the curved surface shape constituting the tooth bottom 22 of the driven plate 20. For this reason, it is difficult to leave traces (striking marks) in which the arm member 3L or 3R is pressed against the external teeth 21 or the tooth bottoms 22 of the driven plate 20. For this reason, the incidence rate of defective products due to the appearance shape can be kept low, and the productivity is excellent.

  In addition, since the urging force for returning to the initial position is applied to the arm member 3L or 3R, after adjusting the positional deviation of the external teeth 21 between the driven plates 20, the stacked driven plates are stacked. When the base 2 is moved away from 20, the arm member 3L or 3R returns to the initial position. That is, since the operation for returning the arm members 3L and 3R is not required, the operation for stacking the driven plate 20 provided with the plurality of external teeth 21 in a state where the external teeth 21 are aligned is continuous. It is effective when it is performed.

  Further, as in the present embodiment, by forming a clearance C between the columnar portion 12 and the opening A of the driven plate 20 so that play is provided between the columnar portion 12 and the driven plate 20, the arm member Even if 3L or 3R interferes with the external teeth 21 of the driven plate 20, such interference can be released by releasing the driven plate 20, so the phase shift of the external teeth 21 between the driven plates 20 is ensured. Can be adjusted.

  The above description shows preferred forms of the present invention, but various modifications can be made within the scope of the claims. For example, although the device of this embodiment has been described as providing a drum brake in an automatic transmission case, it may be used when a drum clutch is assembled. In addition, the present invention is not limited to use in an assembly operation of a wet multi-plate clutch or a wet multi-plate brake, and can be used for various applications.

It is a perspective view which shows typically the working device which is one form of this invention for piled up the driven plate provided with the external tooth alternately with the drive plate when assembling the drum brake in the automatic transmission case. It is a principal part perspective view which shows typically the working device of the same form with the state before the outer teeth of the stacked driven plate are aligned.
