Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the embodiment, an example of a friction fastening device installed in an automobile as a part having a plurality of plates will be described.

FIG. 1 is a diagram showing a configuration of a friction fastening device.
FIG. 2A is a diagram showing the fitting of the drive plate and the shaft, and FIG. 2B is a diagram showing the fitting of the driven plate and the case. For the sake of clarity, the driven plate and the case are not shown in FIG. 2A, and the drive plate and the shaft are not shown in FIG. 2B.

As shown in FIG. 1, the friction fastening device is a so-called wet multi-plate clutch, and includes a donut-shaped laminated body 10 of a plurality of plates. The laminate 10 is exteriorized on the outer periphery of the shaft 13 into which the rotational torque generated by an engine (not shown) is input, and is housed inside the cylindrical case 14.

The shaft 13 is rotatably supported by the case 14 via a needle bearing NB. The laminate 10 is formed by alternately stacking the drive plate 11 and the driven plate 12 in the direction of the rotation axis of the shaft 13. Since the central axis of the laminated body 10 coincides with the rotation axis of the shaft 13, these are collectively referred to as the X axis.

As shown in FIG. 2A, a plurality of engaging claws 11a are formed on the inner peripheral edge of the drive plate 11. The plurality of engaging claws 11a are formed at equidistant positions in the circumferential direction of the X-axis, and between the engaging claws 11a on the inner peripheral edge are recesses 11b recessed outward in the radial direction of the X-axis. As shown in FIG. 1, facing materials 18 are formed on both sides of the drive plate 11, but the drawings are omitted in FIGS. 2A and 3A for simplification. ..

As shown in FIG. 2B, a plurality of engaging claws 12a are formed on the outer peripheral edge of the driven plate 12. The plurality of engaging claws 12a are formed at equidistant positions in the circumferential direction of the X-axis, and between the engaging claws 12a on the outer peripheral edge are recesses 12b recessed inward in the radial direction of the X-axis.

The drive plate 11 has a smaller diameter than the driven plate 12, and as shown in FIG. 1, the engaging claw 11a of the drive plate 11 is located on the inner peripheral side of the laminated body 10, and the engaging claw 12a of the driven plate 12 is the laminated body. It is located on the outer peripheral side of 10.

A spline 13a to which the engaging claw 11a of the drive plate 11 engages is formed on the outer periphery of the shaft 13 along a direction parallel to the X axis. As shown in FIG. 2A, the grooves forming the spline 13a of the shaft 13 are located at equidistant positions in the circumferential direction of the X-axis at the same intervals as the engaging claws 11a formed on the inner peripheral edge of the drive plate 11. It is formed. By fitting the engaging claw 11a of each drive plate 11 into the groove of the spline 13a, the drive plate 11 cannot rotate relative to the shaft 13 and can move relative to the X-axis direction.

As shown in FIG. 1, the shaft 13 and the laminate 10 are housed in the case 14, but the engaging claws 12a of the driven plate 12 are provided on the inner wall surface of the case 14 along the direction parallel to the X axis. An engaging spline 14a is formed. As shown in FIG. 2B, the grooves forming the spline 14a of the case 14 are equidistantly arranged in the circumferential direction of the X-axis at the same intervals as the engaging claws 12a formed on the outer peripheral edge of the driven plate 12. It is formed. By fitting the engaging claw 12a of each driven plate 12 into the groove of the spline 14a, the driven plate 12 cannot rotate relative to the case 14 and can move relative to the X-axis direction.

As shown in FIG. 1, the laminated body 10 is sandwiched between the retaining plate 15 positioned by the snap ring 17 from the X-axis direction and the hydraulic piston 16 inside the case 14. The hydraulic piston 16 is driven in the X-axis direction toward the laminated body 10 by supplying oil pressure to the hydraulic chamber R, and presses the laminated body 10 together with the retaining plate 15. The driven plate 12 of the pressed laminate 10 and the drive plate 11 come into contact with each other to generate a frictional force, and the braking torque is transmitted through the spline 14a of the case 14, the driven plate 12, the drive plate 11 and the spline 13a of the shaft 13. The rotation of the shaft 13 is restricted.

In order to fit the engaging claws 11a of each drive plate 11 to the splines 13a of the shaft 13 when assembling the laminated body 10 constituting the friction fastening device, the engaging claws 11a of each drive plate 11 are fitted in the laminated body 10. Need to be aligned in the same phase when viewed from the X-axis direction.
Further, in order to fit the engaging claws 12a of each driven plate 12 to the spline 14a of the case 14, the engaging claws 12a of each driven plate 12 are aligned in the same phase when viewed from the X-axis direction in the laminated body 10. There is a need.

In the embodiment, a container is used to form a laminated body 10 in which the phases of a plurality of plates are pre-matched. Then, using the assembling jig, the laminated body 10 is taken out of the container in a state of maintaining the phase and assembled to the friction fastening device.

FIG. 3A is a top view of the container 20 forming the laminated body 10, and FIG. 3B is a sectional view taken along the line AA of FIG. 3A. In FIG. 3A, the drive plate 11 is cross-hatched for easy understanding.

As shown in FIG. 3A, the container 20 is a box-shaped member having an open upper end. Although the details will be described later, since the central axis of the container 20 is set to coincide with the central axis of the laminated body 10 by the arrangement of the pins 21 and 22, the central axis of the container 20 is also referred to as the X axis.
As shown in FIG. 3B, a donut-shaped raising table 23 is placed on the bottom surface of the container 20.
The drive plate 11 and the driven plate 12 are alternately stacked and placed in the container 20 to form the laminated body 10. The laminated body 10 is raised by the raising table 23, and the lowermost plate (the lowermost plate ( In the illustrated example, the driven plate 12) is housed in the container 20 with a clearance C with respect to the bottom surface of the container 20 on the inner peripheral edge side.

Pins 21 and 22 for matching the phases of the drive plate 11 housed inside the container 20 and the engaging claws 11a and 12a of the driven plate 12 are attached to the container 20.
Pins 21 and 22 are rod-shaped members that are erected vertically from the bottom of the container 20 toward the upper end of the container 20.

The distance D1 from the X-axis of the container 20 to the tangent line passing through the outermost point in the radial direction of the outer peripheral surface of the pin 21 corresponds to the distance from the X-axis of the laminated body 10 to the recess 11b of the drive plate 11.
The distance D2 from the X-axis of the container 20 to the tangent line passing through the innermost point in the radial direction of the outer peripheral surface of the pin 22 corresponds to the distance from the X-axis of the laminated body 10 to the recess 12b of the driven plate 12.
The pins 21 and 22 are provided to position the engaging claws 11a and 12a of the drive plate 11 and the driven plate 12 when the laminated body 10 is formed in the container 20.

When the drive plate 11 is placed in the container 20, the pin 21 is fitted into one of the recesses 11b, the engaging claw 11a is brought into contact with the pin 21, and the drive plate 11 is placed on the previously stacked driven plate 12. Place it. By placing all the drive plates 11 in the container 20 with the engaging claws 11a in contact with the pins 21, the phases of the engaging claws 11a of the drive plates 11 are aligned in the laminated body 10. Since the engaging claws 11a and the recesses 11b are set at equidistant positions in the circumferential direction, if one recess 11b is positioned, the phases of all the engaging claws 11a and the recesses 11b are aligned. When the size of the pin 21 is smaller than that of the recess 11b, the pin 21 is brought into contact with one of the determined peripheral ends of the recess 11b.

When the driven plate 12 is placed in the container 20, the pin 22 is fitted in one of the recesses 12b, and the engaging claw 12a is brought into contact with the pin 22 to be placed on or in front of the raising table 23. It is placed on the stacked drive plates 11. By placing all the driven plates 12 in the container 20 with the engaging claws 12a in contact with the pins 22, the phases of the engaging claws 12a of the driven plates 12 are aligned in the laminated body 10. Since the engaging claws 12a and the recesses 12b are set at equidistant positions in the circumferential direction, if one recess 12b is positioned, the phases of all the engaging claws 12a and the recesses 12b are aligned. When the size of the pin 22 is smaller than that of the recess 12b, the pin 22 is brought into contact with one of the predetermined ends of the recess 12b in the circumferential direction.

By stacking a plurality of plates in the container 20 in which the pins 21 and 22 are arranged in this way, the laminated body 10 in a state in which the phases of the engaging claws 11a and 12a are in advance is formed. The assembly jig moves the laminated body 10 from the container 20 while maintaining the phase, and assembles the laminated body 10 into the case 14 of the friction fastening device.

FIG. 4 is a diagram showing an assembling jig of the laminated body 10.
As shown in FIG. 4, the assembly jig 30 includes a holding mechanism 31 that sandwiches the laminated body 10 along the X-axis direction of the laminated body 10. The holding mechanism 31 is composed of a rotating member 32 and a plate retainer 33. The rotating member 32 wraps around from the inner peripheral edge of the laminated body 10 to the lower side to press the laminated body 10 from below, and the plate retainer 33 presses the laminated body 10 from above in the X-axis direction, so that the holding mechanism 31 is the laminated body. Insert 10 and lock it. The locked laminate 10 is taken out from the container 20 (see (a) in FIG. 3), assembled to the case 14 (see FIG. 1) as it is, and then unlocked to change the phases of the engaging claws 11a and 12a. The combined laminate 10 can be assembled.

The assembly jig 30 includes an arm portion 34 which is a mechanism for rotating the rotating member 32.
The arm portion 34 includes a tubular member 35, a rod 36 that slidably inserts the inside of the tubular member 35, and a link 37 that connects the rod 36 and the rotating member 32.

The rod 36 is driven up and down along the central axis direction of the tubular member 35 by a drive mechanism (not shown) or manually. When the assembly jig 30 sandwiches the laminated body 10, the central axis of the tubular member 35 and the X-axis, which is the central axis of the laminated body 10, substantially coincide with each other. Therefore, the central axes of the tubular member 35 are also combined. It is called the X axis.

The rod 36 extends downward from the lower end of the tubular member 35, and a pair of links 37 are attached to the extended portion via a fastener 38 such as a bolt. The portion of the rod 36 to which the link 37 is attached may have a flat surface, for example, by cutting.

Each of the pair of links 37 has an elongated plate shape, and an elongated hole 37c extending along the longitudinal direction of the link 37 is formed at one end portion 37a attached to the rod 36. The elongated holes 37c of the pair of links 37 are overlapped so as to overlap with each other when viewed from the radial direction of the X-axis, and the fastener 38 penetrates both elongated holes 37c and is attached to the rod 36.
Although an example including two arm portions 34 is shown here, the number of arm portions 34 may be three or more.

In the vicinity of the lower end of the tubular member 35 through which the rod 36 is inserted, a disk 39 protruding radially outward from the outer circumference of the tubular member 35 is externally fitted and fixed. A pair of fixing members 40, 40 extending below the disk 39 are attached to the outer edge of the lower surface of the disk 39. The pair of fixing members 40, 40 are arranged at intervals of approximately 180 ° in the circumferential direction around the X axis of the tubular member 35.

The other end 37b of the pair of links 37 is rotatably attached to the lower ends of the pair of fixing members 40 and 40 via fasteners 41 such as bolts, respectively. Therefore, in the pair of links 37, one end 37a is overlapped with the rod 36, but the other end 37b is located at a distance of approximately 180 ° in the circumferential direction around the X axis of the rod 36. There is.

When the rod 36 moves up and down, the fastener 38 moves up and down while sliding in the elongated hole 37c of the one end 37a of the link 37, so that the one end 37a of the link 37 is pushed up or down. At this time, since the other end 37b of the link 37 is fixed to the fixing member 40, the other end 37b rotates about the fastener 41.

The main body 32a of the rotating member 32 is fixed to the other end 37b of the pair of links 37, respectively. The main body 32a of the rotating member 32 extends below the link 37 in a direction orthogonal to the longitudinal direction of the link 37. The tip portion 32b connected to the lower end of the main body portion 32a of the rotating member 32 bends substantially at a right angle to the main body portion 32a and extends outward in the radial direction of the X-axis.

Since the rotating member 32 is fixed to the other end 37b of the link 37, when the rod 36 moves up and down, the rotating member 32 rotates about the other end 37b of the link 37 according to the principle of leverage.

FIG. 5 is a diagram showing the movement of the arm portion 34 in the locking direction.
FIG. 6 is a diagram showing the movement of the arm portion 34 in the release direction.
In addition, in FIG. 5 and FIG. 6, for the sake of clarity, only one of the link 37 and the rotating member 32 before movement is shown by a two-dot chain line. Further, the hatching of the assembly jig 40 shown in FIG. 4 is omitted in FIGS. 5 and 6.
As shown in FIG. 5, when the rod 36 moves downward, the tip end portion 32b of the rotating member 32 rotates from the radial inside to the radial outside of the X-axis. As shown in FIG. 6, when the rod 36 moves upward, the tip end portion 32b of the rotating member 32 rotates from the radial outer side of the X-axis toward the radial inner side.

Although details will be described later, as shown in FIG. 5, the rotating member 32 rotates outward in the radial direction to sandwich and lock the laminated body 10 together with the plate retainer 33. Then, as shown in FIG. 6, the rotating member 32 rotates inward in the radial direction to separate from the laminated body 10 and release the lock. That is, the downward movement of the rod 36 of the arm portion 34 means "movement in the locking direction", and the upward movement of the rod 36 means "movement in the releasing direction".

As shown in FIG. 5, when the rod 36 moves downward, one end 37a of the pair of links 37 moves to a position where it is horizontally aligned with the other end 37b. At this time, the main body portion 32a of the rotating member 32 extends downward in the vertical direction, and the tip portion 32b of the rotating member 32 extends in the horizontal direction. The rotating member 32 locks the laminated body 10 together with the plate retainer 33 at the position A where the tip portion 32b extends in the horizontal direction.

A ball plunger 42 is attached to the tubular member 35 so as to penetrate the outer peripheral surface. A hole 36a into which the ball blancer 42 is fitted is formed on the outer peripheral surface of the rod 36. The hole portion 36a is provided at a position facing the ball plunger 42 when the rotating member 32 is at the position A. As a result, when the rotating member 32 stops the rod 36 at the position A, the ball plunger 42 fits into the hole 36a, so that the rotating member 32 is positioned at the position A. When the rod 36 is moved upward or downward again, the ball plunger 42 is separated from the hole 36a and the rotating member 32 starts rotating again.

As shown in FIG. 4, the assembly jig 30 includes a disk 43 and a pair of support members 44, 44 as a support portion of the plate retainer 33.

The disk 43 is fixed to the outer peripheral surface near the upper end of the tubular member 35 and projects outward in the radial direction of the X-axis. Two through holes are formed near the outer edge of the disk 43 at intervals of approximately 180 ° in the circumferential direction around the X axis of the tubular member 35, and a pair of support members 44, 44 are vertically placed in the through holes. It is inserted so that it can slide in the direction. In the illustrated example, the pair of support members 44, 44 are arranged at the same circumferential position as the pair of arm portions 34, but the circumferential position of the pair of support members 44, 44 is not limited, and the pair of arms It may be arranged at a position in the circumferential direction different from that of the portion 34.

A stopper 45 for preventing the support member 44 from falling off is attached to the upper end of the pair of support members 44, 44 located above the disk 43. A plate retainer 33 is suspended from the lower ends of the pair of support members 44, 44 located below the disc 43.

The plate retainer 33 has a cylindrical shape with a bottom at the upper end, and a tubular member 35 inserts a through hole formed at the center of the shaft. The plate retainer 33 covers the radial outer sides of the pair of fixing members 40, 40 and the link 37 and extends downward.

The outer diameter of the plate retainer 33 is set to be larger than the inner diameter of the uppermost plate (drive plate 11 in the illustrated example) of the laminate 10 and smaller than the outer diameter, and the plate retainer 33 is used to set the donut-shaped laminate. The size is set so that 10 can be pressed from above.

A spring 46 is wound around a portion of the pair of support members 44, 44 below the disk 43 on the outer circumference. The spring 46 comes into contact with the disk 43 and the plate retainer 33, and urges the plate retainer 33 downward.

A method of assembling the laminated body 10 to the friction fastening device by using the assembling jig 30 having the above configuration will be described. FIG. 5 illustrates a mode in which the laminate 10 formed by the assembly jig 30 is taken out from the container 20, and FIG. 6 illustrates a mode in which the laminate 10 is assembled to the case 14 of the friction fastening device by the assembly jig 30. ..

As shown in FIG. 5, the laminated body 10 is housed in the container 20 in a state where the plurality of plates are in phase with each other.
The assembling jig 30 is inserted into the inside from the open upper end of the container 20, and the assembling jig 30 is lowered toward the bottom surface of the container 20 while inserting the rotating member 32 into the inner peripheral side of the laminate 10 housed in the container 20. Let me. At this time, the rod 36 is moved upward, and the tip portion 32b of the rotating member 32 is moved to a position B (see FIG. 4) that does not interfere with the inner peripheral edge of the laminated body 10.
The assembly jig 30 is lowered, and the lower end of the plate retainer 33 is pressed from the upper side of the laminated body 10. The plate retainer 33 presses the laminated body 10 from above along the X-axis direction by the urging force of the spring 46.

When the tip portion 32b of the rotating member 32 reaches the bottom surface of the container 20, the rod 36 is moved downward to rotate the tip portion 32b of the rotating member 32 to the position A. When the rod 36 is stopped at the position A, the ball plunger 42 is fitted into the hole 36a of the rod 36, and the rotating member 32 is positioned at the position A.

As described above, the laminated body 10 is raised by the raising table 23 placed on the bottom surface of the container 20, and between the inner peripheral edge side of the lowermost plate of the laminated body 10 and the bottom surface of the container 20. There is a clearance C. Therefore, the tip portion 32b that has rotated to the position A penetrates into the clearance C and wraps around to a position facing the lower surface of the lowermost plate of the laminated body 10.

Since the plate retainer 33 that presses the upper side of the laminated body 10 is urged by the spring 46, when the tip portion 32b of the rotating member 32 wraps around to the lower side of the laminated body 10, the urging force of the spring 46 is applied to the laminated body 10. The lower side of the laminated body 10 is abutted against and supported by the tip portion 32b of the rotating member 32. In this way, the sandwiching mechanism 31 composed of the plate retainer 33 and the rotating member 32 sandwiches the laminated body 10 from above and below along the X-axis direction. By being sandwiched from above and below, a frictional force acts between the plurality of plates of the laminated body 10, and the laminated body 10 is locked in a state where the plates are in phase with each other. Further, since the main body portion 32a of the rotating member 32 contacts and supports the inner peripheral edge of the laminated body 10, the laminated body 10 is held by the assembly jig 30 in a stable state.

When the entire assembly jig 30 is raised and pulled out from the upper end opening of the container 20 with the laminated body 10 locked, the laminated body 10 keeps the phases of the engaging claws 11a and 12a aligned and is outside the container 20. Pulled out to.

As shown in FIG. 6, the laminated body 10 held by the assembly jig 30 is assembled to the case 14 of the friction fastening device. The laminate 10 is assembled after the hydraulic piston 16 is assembled to the case 14 and before the shaft 13 (see FIG. 1) is assembled. At the time of assembly, the case 14 is arranged so that the hydraulic piston 16 is located on the lower side.

The assembly jig 30 that holds the laminated body 10 pulled out from the container 20 is inserted into the case 14, and the lowermost plate of the laminated body 10 is lowered to the set position where it abuts on the hydraulic piston 16.

At this time, the engaging claw 12a of the driven plate 12 of the laminated body 10 is fitted to the spline 14a of the case 14. Since the engaging claws 12a of all the driven plates 12 of the laminated body 10 are in phase with each other, the engaging claws 12a of the driven plate 12 located at the bottom are fitted to the spline 14a, and the assembly tool 30 is X. By moving the driven plate 12 downward in the axial direction, the engaging claws 12a of all the driven plates 12 can be smoothly fitted to the spline 14a of the case 14.

When the accommodation of the laminated body 10 in the case 14 is completed, the rod 36 of the assembly jig 30 is moved upward. When the rod 36 is moved, the ball plunger 42 is separated from the hole portion 36a of the rod 36, the tip portion 32b of the rotating member 32 is rotated inward in the radial direction from the position A, and the lowermost plate of the laminated body 10 is formed. Since it is separated from the lower surface, the laminated body 10 is unlocked.
The assembly of the laminate 10 is completed by rotating the rotating member 32 to a position B (see FIG. 4) that does not interfere with the inner circumference of the laminate 10 and then pulling out the entire assembly jig 30 from the inside of the case 14. To do.

After pulling out the assembly jig 30, the shaft 13 shown in FIG. 1 is inserted into the inner circumference of the laminated body 10 for assembly. At this time, the engaging claw 11a of the drive plate 11 of the laminated body 10 is inserted into the shaft 13. It is fitted to the spline 13a. In the embodiment, since the phases of the engaging claws 11a of all the drive plates 11 of the laminated body 10 are aligned in advance, the engaging claws 11a of the drive plate 11 located at the top are fitted into the splines 13a of the shaft 13. By matching and moving the shaft 13 downward in the X-axis direction, the engaging claws 11a of all the drive plates 11 can be smoothly fitted to the splines 13a of the shaft 13.

Here, when the laminated body 10 is assembled to the friction fastening device without using the assembling jig 30 of the embodiment, for example, the drive plate 11 and the driven plate 12 are alternately stacked inside the case 14 and the laminated body 10 is directly stacked. Is conceivable to form. In this case, when the driven plate 12 is put inside the case 14, the engaging claw 12a needs to be fitted to the spline 14a of the case 14, so that the phase of the engaging claw 12a is changed when the laminate 10 is formed. Although they match, the phases of the engaging claws 11a of the drive plate 11 are not aligned.

If the phases of the engaging claws 11a are not aligned, the engaging claws 11a and the shaft of each drive plate 11 are rotated in order from the top of the laminate 10 while rotating the shaft 13 clockwise and counterclockwise around the X axis. It is necessary to fit the spline 13a of 13. In this case, it takes time to assemble, and there is a concern that scratches, dents, etc. may occur in contact with the drive plate 11 when the shaft 13 is rotated.

In the embodiment, the container 20 forms a laminated body 10 in which the engagement claws 11a and 12a of the drive plate 11 and the driven plate 12 are in phase with each other, and the assembly jig 30 locks the laminated body 10 in phase with each other. Since it is assembled to the friction fastening device as it is, the time required for the assembling work is reduced, and it is possible to prevent the laminated body 10 from being scratched or dented due to the assembling work.

As described above, the assembly jig 30 of the embodiment is
(1) A jig for assembling a plurality of plates having engaging claws 11a and 12a. The assembly jig 30 has a holding mechanism 31 that sandwiches the laminated body 10 of a plurality of plates along the X-axis direction (axial direction).

The sandwiching mechanism 31 of the jig 30 for assembling parts such as a multi-plate wet clutch sandwiches the laminated body 10 of a plurality of plates from the X-axis direction (vertical direction) of the laminated body 10, and the laminated body 10 is not separated by frictional force. The laminated body 10 is locked as described above. As a result, if the phases of the engaging claws 11a and 12a of the plurality of plates are matched in advance and the laminated body 10 is carried by sandwiching the laminated body 10 with the holding mechanism 31 in the matched phase, the engaging claws 11a and 12a can be directly used. Since it can be assembled to other parts such as the case 14 and the shaft 13, it is possible to reduce the time and effort for assembling the plates in phase with each other on the production line, and it is possible to improve the work efficiency.

(2) The assembly jig 30 has an arm portion 34. The pinching mechanism 31 is composed of a rotating member 32 (first pinching member) and a plate holder 33 (second pinching member), and the pinching mechanism 31 moves the arm portion 34 downward (locking direction). The rotating member 32 rotates and wraps around to a position facing the laminated body 10.

By moving the arm portion 34 downward (locking direction), the laminated body 10 can be sandwiched by the sandwiching mechanism 31 composed of the rotating member 32 and the plate retainer 33, and the laminated body 10 can be held. The operation of the assembling jig 30 for sandwiching is simple, and the labor for assembling can be reduced. In the example of the embodiment, the locking direction is the direction along the X-axis direction of the laminated body 10, that is, the direction parallel to the X-axis direction, but this is just an example, and the locking direction is in a specific direction. Not limited. The configuration of the arm portion 34 for rotating the rotating member 32 is not limited to that described in the embodiment, and can be appropriately changed.

(3) The drive plate 11 and the driven plate 12 (plate) are donut-shaped. The rotating member 32 of the assembly jig 30 rotates on the inner peripheral side of the drive plate 11 and the driven plate 12.

The rotating member 32 may be configured to rotate from the outer peripheral side of the drive plate 11 and the driven plate 12 to sandwich the laminated body 10, but the laminated body may be placed in a narrow space such as inside the case 14 of the friction fastening device. When the 10 is set, the rotating member 32 rotates on the inner peripheral side of the drive plate 11 and the driven plate 12, thereby preventing the rotating member 32 from interfering with the case 14 and the like, and assembling smoothly. Can be attached.

(4) The assembly jig 30 has a spring 46 (a urging member) that applies a downward urging force (direction toward the laminated body 10) to the plate retainer 33.

By providing the spring 46 on the plate retainer 33 and applying an urging force, it is possible to increase the frictional force between the plurality of plates and prevent the laminate 10 from shifting when the laminate 10 is sandwiched. Further, since the spring 46 is provided on the plate retainer 33 on the non-rotating side, the rotating member 32 rotates to sandwich the laminated body 10 and then quickly rotates from the plate retainer 33 via the laminated body 10. It is preferable that an urging force toward the member 32 is applied.

(5) In the holding mechanism 31 of the assembly jig 30, the rotating member 32 is rotated by moving the arm portion 34 in the release direction opposite to the lock direction, and the lock of the laminated body 10 is released. It is a thing.

By moving the arm portion 34 in the upward direction (release direction), the rotating member 32 rotates in the opposite direction, and the laminated body 10 can be unlocked. After unlocking, the shaft 13 of the assembly jig 30 may be pulled out upward, so that a plurality of plates can be easily assembled in the case 14 in a state where the phases are aligned.

The manufacturing method of the embodiment is
(6) A method for manufacturing a part having a plurality of plates of a drive plate 11 having engaging claws 11a and 12a and a driven plate 12.
In the manufacturing method, the engaging claws 11a and 12a of the laminated body 10 of a plurality of plates are placed in a state of being aligned in phase and raised so as to form a clearance C on the lowermost plate of the laminated body 10.
The rotating member 32 is rotated by rotating the rotating member 32 while pressing the plate holding 33 of the assembly jig having the holding mechanism 31 having the rotating member 32 and the plate holding 33 from the upper side of the laminated body 10. The laminated body 10 is locked by the sandwiching mechanism 31 by wrapping around to a position facing the laminated body 10.
The laminate 10 is set at the set position by unlocking the sandwiching mechanism 31 at the set position of the laminate 10.

As a result, if the phases of the engaging claws 11a and 12a of the plurality of plates are matched in advance and the laminated body 10 is carried by sandwiching the laminated body 10 with the holding mechanism 31 in the matched phase, the engaging claws 11a and 12a can be directly used. Since it can be assembled to other parts such as the case 14 and the shaft 13, it is possible to reduce the time and effort for assembling the plates in phase with each other on the production line, and it is possible to improve the work efficiency.

In the embodiment, the friction fastening device has been described as a part having a plurality of plates having engaging claws, but the present invention is not limited to this, and the present invention is not limited to the parts having a plurality of plates having other engaging claws.
