DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method of assembling an endless metal belt used as a belt for a CVT (Continuously Variable Transmission) and a jig for assembling the same.

[0002]

2. Description of the Related Art FIGS. 1A and 1B show a general structure of an endless metal belt for CVT. As shown in FIG.
The endless metal belt 1 for VT is configured by assembling a plurality of elements 2 made of a metal plate and a pair of laminated rings 4 and 4 formed by laminating a plurality of thin metal rings 3. As shown in FIG. 1B, each element 2
A body 5 contacting a pulley (not shown) of the CVT,
A head 7 is connected to the body 5 via a neck 6, and a pair of recesses 8, 8 are formed between the body 5 and the head 7 on both sides of the neck 6. Then, each recess 8 of each of the plurality of elements 2 is fitted to a side portion of each of the laminated rings 4, and the plurality of elements 2 are connected as shown in FIG.
As shown in FIG. 1, the belt 1 is formed by arranging and laminating the laminated rings 4 in a circumferential direction in the circumferential direction. Further, dimples 9 projecting in the arrangement direction are formed on the surface of the head 7 of each element 2, and holes 10 (depressed) corresponding to the dimples 9 are formed on the back of the head 7. 1 (b) is formed.
The dimple 9 of each element 2 is inserted into the hole 10 of the element 2 adjacent to the element 2.

As a technique for assembling an endless metal belt of this kind, a technique as disclosed in, for example, JP-A-2000-205344 is known.

In this technique, one of the plurality of recesses (lower side recess) of a plurality of elements is fitted into a dummy ring member held linearly in a vertical posture, and then the dummy ring member is deformed into an annular shape. As a result, a plurality of elements are arranged in a ring on the dummy ring.
Then, in this state, one laminated ring is fitted into the other concave portion (upper concave portion) of the element from above. Furthermore, the elements of the annular arrangement in which the laminated rings are fitted are held while maintaining the annular arrangement state,
In this state, the elements of the annular arrangement are disengaged from the dummy ring by moving the elements of the annular arrangement upward together with the laminated ring fitted thereto. Thereafter, the elements of the annular array are moved over another stacking ring mounted on the required location, and the elements of the annular array are concentrically lowered toward the other stacking ring. Thereby, the other concave portion (lower concave portion) of the element is fitted to the other laminated ring.

However, such a technique requires a step of deforming a dummy ring in which a plurality of elements are fitted into an annular shape, and a step of detaching the elements arranged in an annular shape on the dummy ring from the dummy ring. Therefore, there is a disadvantage that the number of steps is large and the working efficiency is poor. Further, a device for deforming the linear dummy ring into a ring or a device for holding the ring in an annular state in order to detach the elements of the ring arrangement from the dummy ring is required, which makes the assembly device complicated and complicated. There was also the inconvenience of becoming.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and has as its object to provide a method of assembling an endless metal belt which can efficiently and easily assemble an element and a lamination ring. With the goal.

It is another object of the present invention to provide a jig for assembling an endless metal belt which can smoothly assemble an endless metal belt by the assembling method with a simple configuration.

[0008]

According to the present invention, there is provided a method for assembling an endless metal belt, comprising: a plurality of plates having a pair of recesses between a body and a head connected to the body; Of the endless metal belt in which one of the recesses of each of the element-shaped elements is fitted to a side portion of a laminated ring formed by laminating a plurality of rings, and the plurality of elements are arranged in a circumferential direction of the laminated ring. In the assembling method, after the lamination ring is rotatably supported on a gantry with its axis centered in a vertical direction, the lamination ring is extended from a diagonally upper direction to a position directly above a part of the lamination ring in a substantially tangential direction of the lamination ring. The plurality of elements, which are arranged by fitting the one of the concave portions in advance into existing guide rails, are pushed toward a part of the lamination ring along the guide rails, whereby the plurality of The elements are sequentially transferred to the lamination ring so that one of the recesses is fitted to the side of the lamination ring while being detached from the guide rail, and the lamination ring is rotated around its axis, and the plurality of elements are rotated. The element is arranged in the circumferential direction of the lamination ring.

According to the present invention, the plurality of elements arranged by fitting the one concave portion into the guide rail are arranged along the guide rail toward a part of the laminated ring supported on the gantry. It is supplied from a diagonally upper part of the part. At this time, since the guide rail extends in a substantially tangential direction of a part of the lamination ring, the concave portion of the element fitted to the guide rail is smoothly detached from the guide rail and formed on the lamination ring. Fitted and transferred to the lamination ring. Here, the element fitted to the lamination ring is slid in the circumferential direction to some extent along the lamination ring in the vicinity of the tip end of the guide rail by pushing the subsequent element from the guide rail side. However, since the laminated ring is curved as a whole in the direction in which the guardrail extends (the pushing direction of the element), the element does not easily slide on the laminated ring. For this reason, in the present invention, the stacking ring is rotated around its axis while transferring the element from the guide rail to the stacking ring, thereby transferring the element from the guide rail to the stacking ring. Can be continuously performed without any trouble, and the elements can be arranged in the circumferential direction of the lamination ring.

In this case, the pushing force of the element from the guide rail to the lamination ring becomes a rotational driving force of the lamination ring due to the sliding resistance of the element against the lamination ring. For this reason, the stacking ring can be rotated with the pushing of the element from the guide rail to the stacking ring without an actuator for applying a rotational driving force to the stacking ring.

In this manner, according to the assembling method of the present invention, the plurality of elements arranged on the guide rail are directly and smoothly fitted and transferred from the guide rail to the lamination ring while being transferred to the lamination ring. They can be arranged in the circumferential direction, and the element and the lamination ring can be efficiently and easily assembled.

In the assembling method of the present invention, preferably, the arc-shaped portion near a part of the lamination ring supported on the gantry extends in substantially the same direction as the direction in which the guide rail extends. The transfer of the plurality of elements from the guide rail to the stacking ring is started with the shape of the stacking ring regulated.

According to this, even when the diameter of the lamination ring is relatively small, the portion of the lamination ring extending in the same direction as the guide rail becomes longer, and as a result, the lamination ring extends from the guide rail. The transfer of the element to the device can be performed smoothly.

Further, in the assembling method according to the present invention, at least when the respective recesses of the plurality of elements are fitted to the side portions of the lamination ring while being detached from the guide rails, the head and the body of each of the elements are provided. Preferably, the method further comprises a step of slidably supporting one of the lower end portion and the other upper portion.

That is, when each of the recesses of the plurality of elements is fitted to the side of the lamination ring while being detached from the guide rail, the fitting of the recess to both the guide rail and the lamination ring is required. Since an insufficient state occurs, the element may fall off. However, according to the present invention, in such a state, the lower end of one of the head and the body of each element and the upper end of the other are slidably supported, so that the above-mentioned inconvenience can be ensured. Can be avoided
The transfer of the element from the guide rail to the lamination ring can be performed reliably and smoothly.

According to another aspect of the present invention, there is provided a jig for assembling an endless metal belt, comprising: a plurality of plate-like members having a pair of concave portions between a body and a head connected to the body; Assembling an endless metal belt in which one concave portion of each of the elements is fitted to a side portion of a laminated ring formed by laminating a plurality of rings, and the plurality of elements are arranged in a circumferential direction of the laminated ring. A jig for supporting the lamination ring rotatably with its axis centered in the vertical direction, and a part of the lamination ring supported on the gantry obliquely from above and toward the part. A guide rail extending substantially in a tangential direction of the lamination ring, and a guide rail for fitting one of the recesses of each of the plurality of elements to slidably arrange and support the plurality of elements; Support on It is characterized in that a portion of the laminated ring and a positioning restricting means for positioning a position just below the tip of the guide rails that.

According to the present invention, the concave portion is fitted to the guide rail while a part of the lamination ring supported on the gantry is positioned by the positioning means at a position immediately below the tip of the guide rail. By pushing a plurality of elements arranged along the guide rail toward a part of the lamination ring along the guide rail, the concave portions of the elements arranged on the guide rail are separated from the tip end of the guide rail to the lamination ring. The elements are fitted, and the elements are sequentially transferred from the guide rail to the lamination ring. At this time, since the guide rail extends in a substantially tangential direction of a part of the lamination ring positioned just below the distal end thereof, the element is smoothly fitted and transferred from the guide rail to the lamination ring. . Further, as described with respect to the assembling method of the present invention, the stacking ring rotates on the gantry by the pushing force of the elements arranged on the guide rail, so that the element does not need to include a separate actuator for rotationally driving the stacking ring. Can be continuously transferred to the lamination ring, whereby the elements are arranged in the circumferential direction of the lamination ring.

Thus, according to the assembly jig of the present invention, the assembly of the endless metal belt by the above-described assembling method of the present invention can be performed by assembling a simple structure including the gantry, the guide rail, and the positioning means. It can be performed smoothly using a tool.

In the assembling jig according to the present invention, the positioning restricting means may include an arc-shaped portion near a part of the lamination ring in a state where a part of the lamination ring is located immediately below the tip of the guide rail. A receiving member slidably in contact with either one of the inner peripheral surface and the outer peripheral surface of the laminated ring; A pressing portion in which the arc-shaped portion of the lamination ring extends in substantially the same direction as the guide rail and presses against the other peripheral surface in a state of being in contact with the peripheral surface. And a member.

According to this, at the time of positioning the lamination ring with respect to the guide rail, the arc-shaped portion near a part of the lamination ring is substantially between the receiving member and the pressing member in the direction in which the guide rail extends. It is held so as to extend in the same direction. For this reason, even when the diameter of the lamination ring is relatively small, the portion of the lamination ring that extends in the same direction as the guide rail and is positioned immediately below the guide rail becomes longer, and as a result, The fitting and transfer of the element from the guide rail to the laminated ring can be performed smoothly.

In this case, the pressing member is provided so as to be able to protrude and retract above the pedestal by vertically moving a storage hole formed in the pedestal. It is preferable to make contact with and separate from the surface.

According to this, when the arcuate portion of the lamination ring is held between the pressing member and the receiving member as described above, the pressing member receives the elastic force of the lamination ring. The force can be received by the peripheral wall of the storage hole. As a result, the positioning member including the pressing member and the mechanism for moving the pressing member can be reduced in size and simplified, and the arc-shaped portion of the lamination ring can be reliably positioned in a desired state. it can.

Also, in the assembly jig of the present invention, at least at a position near the tip of the guide rail, the lower end of one of the head and the body of the element that moves from the guide rail to the lamination ring. It is preferable to provide a supporting member for supporting the element by slidably contacting the element and the other upper part.

That is, in the vicinity of the distal end of the guide rail, each concave portion of the plurality of elements is fitted to the side of the lamination ring while being detached from the guide rail. At this time, as described with respect to the assembling method of the present invention, there is a possibility that the fitting of the concave portion to both the guide rail and the lamination ring becomes insufficient, and the element may fall off. is there. For this reason, in the assembly jig of the present invention, the supporting member is provided, and the lower end of one of the head and the body of each element and the upper part of the other are supported by the supporting member. As a result, it is possible to reliably avoid a situation in which the element falls off near the tip of the guide rail,
The transfer of the element from the guide rail to the lamination ring can be performed reliably and smoothly.

The inclination angle of the inclined surface 42 of the support member 37 and the fixing member 19 with respect to the first inclined surface 25 of the guide rail 12 is smaller than the inclination angle of the second inclined surface 26 of the guide rail 12. The inclination angle of the first inclined surface 25 with respect to the horizontal plane 24 of the guide rail 12 is substantially the same (an inclination angle that allows the dimple 9 and the hole 10 of the adjacent elements 2 to be kept fitted).

Next, a method of assembling the metal belt 1 using the assembling jig of the present embodiment will be described.

First, after the laminated ring 4 is supported on the ring support portion 14 of the gantry 11 with the axis C of one laminated ring 4 oriented in the vertical direction, the operator can move the rear part of the laminated ring 4 (this (Corresponding to the arc-shaped portion in the invention)
9, the rear part of the lamination ring 4 is deformed so as to be pressed against the front part, and in this state, the gripping part 36 of the drive mechanism 31 is pressed.
And the cam plate 35 is advanced. This allows
Each pressing pin 27 protrudes from the upper side of the gantry 11, and the pressing pin 27 comes into contact with the inner peripheral surface of the laminated ring 4. At this time, the curvature of the rear portion of the lamination ring 4 is reduced as indicated by the imaginary line in FIG. 5, and the rear portion extends in the substantially same direction as the guide rail 12 immediately below the tip of the guide rail 12. Is positioned. In this case, since the laminated ring 4 attempts to restore the original true circular state, the reaction force acts on the pressing pins 27, but the reaction force is
A storage hole 28 in the gantry 11 corresponding to each pressing pin 27
The pressing pin 27 does not move or the positioning state of the lamination ring 4 does not shift.

After swinging the support member 37 to the position shown by the solid line in FIG. 3, the recess 8 is fitted on the guide rail 12 on the horizontal surface 24 of the guide rail 12 by a feeder device (not shown) in advance. The elements 2 which are arranged and stacked in a stack (hereinafter, the elements 2 in this arrangement state may be referred to as an element row (2)) are
2 to the tip side.

At this time, the element row (2) is maintained in a substantially stacked arrangement state (a state in which the dimples 9 and the holes 10 of the adjacent elements 2 are fitted to each other) and the first row from the horizontal plane 24 of the guide rail 12 is maintained. It moves on the inclined surface 25, and moves on the first inclined surface 25 to the tip side of the guide rail 12.

In the process of moving from the first inclined surface 25 of the guide rail 12 to the second inclined surface 26, each element 2 of the element row (2), as shown in FIG. 5 is engaged with and supported by the rear surface of the support member 37, and the lower end of the head 7 of the element 2 is supported by being in contact with the inclined surface 42 of the fixing member 19. The support member 37 and the fixing member 1
9 moves toward the rear of the lamination ring 4 along the inclined surface 42 of FIG. In this case, the second end of the guide rail 12
The inclination angle of the inclined surface 26 depends on the support member 37 and the fixed member 1.
Since the inclined surface 42 of the element 9 is also larger than the inclination angle, the concave portion 8 of each element 2 gradually separates from the guide rail 12 as the element 2 moves.

At the same time, the recess 8 of the element 2 gradually fits into the rear part of the lamination ring 4. At this time, the rear part of the lamination ring 4 extends in substantially the same direction as the guide rail 12, and each of the elements 2 gradually detached from the guide rail 12 has its body 5 and head 7 supported by the support member 37. Is supported by the inclined surface 42 of the fixing member 19, so that the recess 2 of the element 2 fits into the lamination ring 4 without causing the element 2 to fall off, and thus guides the element row (2). The transfer from the rail 12 to the lamination ring 4 proceeds smoothly.

Subsequently, each element 2 fitted to the lamination ring 4 tries to slide in the circumferential direction of the lamination ring 4 along the lamination ring 4 by pushing the subsequent element row (2). Since the laminated ring 4 is curved with respect to the guide rail 12 which is the pushing direction of the element row (2), the sliding resistance of each element 2 with respect to the laminated ring 4 is increased. Therefore, the element column (2)
The element 2 fitted into the laminated ring 4 is guided by the guide plates 16 and 17 by the pushing force of the laminated ring 4, and the laminated ring 4 is moved together with the element 2 along the axis C of the laminated ring 4.
It rotates on the ring bearing 14 around.

As a result, the element row (2) can be fitted to the lamination ring 4 while the element row (2) is continuously supplied from the guide rail 12 to the lamination ring 4 without becoming unable to move. it can.

In this way, the supply and fitting of the element row (2) to the lamination ring 4 progresses, and the top of the element row (2) is placed on the lamination ring 4 and the pressing pin 2
When the stacking ring 4 reaches the vicinity of the vicinity of 7b, the stacking ring 4 cannot be rotated. Therefore, the supply and fitting of the elements 2 slightly smaller than the total number of the elements 2 to be fitted to the stacking ring 4 to the guide stacking ring 4 are completed. Then, the pushing of the element row (2) is stopped.

Then, the driving mechanism 31 of the positioning regulating means 13 is further operated to move the pressing pin 27 into the storage hole 2.
8 to be buried. That is, referring to FIG. 5, the cam plate 35 is detached from the support plate 30 by pulling and moving the grip portion 36 of the drive mechanism 31 rearward, and each pressing pin 27 is moved into the storage hole 28. Buried in
