The cylindrical part 2 a is a part having a substantially cylindrical outer shape with the axis Y as the axis, and the outer shape (circular shape) in the axial direction view of the hollow part 1 a of the cylindrical hollow part 1 is It is a mode that substantially matches the inner shape (circular shape) as viewed in the axial direction (however, the outer diameter circle of the cylindrical part 2a is slightly smaller than the inner diameter circle of the hollow portion 1a).

  In addition, in the present Example, although the example in which the insertion part 2 consists of two cylindrical parts 2a * 2a is illustrated, the number of parts which comprise the insertion part which concerns on application of this invention is not limited to this. Further, an aspect in which the insertion part is composed of one part or an aspect in which three or more parts are composed may be employed.

  And as shown in FIG.1 (c) and FIG. 2, it is the workpiece | work applied to the component assembly apparatus which concerns on this invention by inserting cylindrical part 2a * 2a in the hollow part 1a of the cylindrical hollow part 1, The assembled part 3 which is a part having a substantially cylindrical outer shape is formed. In the formed assembled part 3, the axis X that is the axis of the cylindrical hollow part 1 and the axis Y that is the axis of the cylindrical parts 2 a and 2 a are substantially coincident.

  Moreover, in the present Example, in the formed assembly part 3, the aspect in which the axial center (axis X) of the cylindrical hollow part 1 and the axial center (axis Y) of the columnar parts 2a and 2a substantially coincide is illustrated. However, in the assembled part according to the application of the present invention, it is not always necessary that the axis of the cylindrical hollow part and the axis of the insertion part substantially coincide with each other. The axis of the cylindrical hollow part and the axis of the insertion part It is also possible to adopt a mode in which is eccentric.

Next, the overall configuration of the component assembling apparatus according to the present invention will be described with reference to FIGS.
As shown in FIGS. 3 to 5, a component assembling apparatus 100 that is a first embodiment of the component assembling apparatus according to the present invention is an apparatus for assembling cylindrical components 2 a and 2 a to a cylindrical hollow component 1. Yes, it is composed of a rotary mechanism 20, a cam mechanism 30, a component supply unit 40, a component discharge unit 50, and the like.

First, the rotary mechanism 20 will be described.
The rotary mechanism 20 is a part that forms a mechanism that can transport the cylindrical hollow part 1, the insertion part 2, and the assembled part 3 while holding the cylindrical part 1, the assembly part 2, and the assembly part 3 in a predetermined position. 22 and casing 23 and the like.

  As shown in FIG. 6, the rotary drum 22 is a shaft-like member formed by connecting substantially cylindrical portions having different diameters such as a drum shaft 22a, a drum portion 22b, an insertion pin support portion 22d, and the like. It is rotationally driven by being connected to 21.

  As shown in FIGS. 3 to 5, the drum shaft 22 a is horizontally supported by a main body of a component assembly apparatus 100 (not shown) via a bearing or the like so as to be rotatable. Thereby, the rotating drum 22 is rotationally driven around the drum shaft 22a supported in the horizontal direction. Here, the axis of the drum shaft 22a is defined as an axis B.

  As shown in FIGS. 3 to 6, a concave portion 22c, which is a concave portion, is formed on the outer peripheral surface of the drum portion 22b. The concave portion 22c includes a workpiece (that is, the cylindrical hollow part 1, A work holding jig 24 which is a jig for holding the insertion part 2 and the assembled part 3) is fitted. The cylindrical hollow part 1 or the assembled part 3 can be held by the part holding recess 24a formed in the work holding jig 24, and also by the part holding groove 24b formed in the work holding jig 24. The insertion part 2 (that is, the cylindrical parts 2a and 2a) can be held.

  As shown in FIGS. 3 and 5, the drum portion 22b of the rotary drum 22 is covered with a casing 23 that is formed at a substantially constant distance from the outer peripheral surface of the drum portion 22b. A transfer path 25 for transferring the parts 1 and 2 and the assembled part 3 is formed by a gap having a substantially constant interval formed by the inner peripheral surface of the casing 23 and the outer peripheral surface of the drum portion 22b. The clearance of the transfer path 25 is set to be smaller than the outer dimensions (diameter in the axial direction view) of the parts 1 and 2. For convenience of explanation, the casing 23 and the transfer path 25 are not shown in FIG.

Here, the workpiece holding jig 24 will be described with reference to FIG.
As shown in FIG. 7A, the work holding jig 24 holds the cylindrical hollow part 1 (or the assembled part 3) on the surface that becomes the outer peripheral surface of the drum portion 22b when the work holding jig 24 is mounted. The component holding recess 24a, which is a recess, and the component holding groove 24b, which is a recess for holding the insertion component 2 (that is, the cylindrical components 2a and 2a), are formed.

  The shape of the component holding recess 24a and the component holding groove 24b is specially designed for each shape of the work to be handled (cylindrical hollow part 1, insertion part 2 and assembly part 3). The dimensions and curvatures of the parts 24a and 24b are as follows. It corresponds to each part 1 and 2.

  An axis A is set for the work holding jig 24. The axis A is set assuming an axial position where an insertion pin 32 of the cam mechanism 30 described later is reciprocally displaced in a state where the work holding jig 24 is mounted in the recess 22c.

  Further, the shape of the portion formed by the lower surface portion and the side surface portion of the workpiece holding jig 24 (that is, the portion that fits into the concave portion 22c) is substantially the same as the concave shape of the concave portion 22c formed in the drum portion 22b. The workpiece holding jig 24 can be mounted while being positioned with respect to the drum portion 22b. The work holding jig 24 is fixed to the rotating drum 22 by using a fixing member, a bolt, a nut, or the like (not shown) while being mounted in the recess 22c.

  The component holding recess 24a is formed with a locking surface 24c that locks the displacement of the cylindrical hollow component 1 with respect to the axis X direction. The cylindrical hollow component 1 (or assembled component) held in the component holding recess 24a is formed. 3) The positional deviation with respect to the direction of the axis A (axis X) is limited. Thereby, it becomes possible to insert the insertion component 2 reliably.

  The component holding groove 24b is open with respect to the axis Y direction of the cylindrical components 2a and 2a, and the cylindrical components 2a and 2a can be slid on the component holding groove 24b to be displaced toward the component holding recess 24a. This is possible.

  7B, when the components 1 and 2 are placed in the component holding recess 24a and the component holding groove 24b, respectively, the axial center (axis X) of the cylindrical hollow component 1 and the insertion component 2 The axes (axis Y) are substantially coincident with each other, and the axes X and Y are also substantially coincident with the axis A. In other words, by placing the parts 1 and 2 on the parts 24a and 24b of the work holding jig 24, each part can be simply slid along the part holding groove part 24b toward the hollow part 1a. 1 and 2 can be arranged in a state where the insertion part 2 can be easily inserted into the hollow portion 1a, and the state can be maintained.

  Further, the work holding jig 24 can be exchanged. The work holding jig 24 is specially designed for each part to be assembled. For example, as shown in FIG. 8, the work holding jig 24 of number (i) is replaced with a part holding recess 24a or a part. By exchanging the workpiece holding jig 24 with the number (ii) having a different shape and size of the holding groove 24b, it becomes possible to easily cope with the assembly of various types of components by the single component assembling apparatus 100.

Next, the cam mechanism 30 will be described.
As shown in FIGS. 3 and 4, the cam mechanism 30 forms a mechanism for pressing and displacing the insertion component 2 held by the rotary mechanism 20 (specifically, the work holding jig 24 provided in the rotary drum 22). This is a part, and is constituted by a cylindrical cam 31, an insertion pin 32, a pin support member 33, and the like.

  As shown in FIGS. 3, 4 and 9A, the cylindrical cam 31 is a member in which an endless cam groove 31b is formed in a substantially cylindrical cam main body 31a, and the rotary mechanism 20 (specifically, a rotating drum). The shaft center is common to the axis B which is the rotation axis of 22), and is fixed to the main body frame or the like of the component assembly apparatus 100 (not shown). That is, the cylindrical cam 31 can maintain a stationary state regardless of the rotation even if the rotary drum 22 rotates.

  In the cylindrical cam 31 shown in this embodiment, since the cam body 31a is divided into two members by the cam groove 31b, the divided parts are connected by the connecting members 31c and 31c. A main body 31a is formed. Further, in the present embodiment, the cam groove 31b is formed as an endless cam groove 31b in such a manner that the start and end of the sine curve for one cycle are connected, but the cam formed in the cam mechanism according to the present invention The embodiment of the groove is not limited to this. The behavior of the insertion pin (reciprocating displacement speed / timing, reciprocating displacement amount, etc.) can be controlled by variously adjusting the cam groove.

As shown in FIG. 9B, the insertion pin 32 is a substantially cylindrical rod-like member having a pin main body 32 a, a pressing portion 32 b, a protruding portion 32 c and the like, and is inserted by the work holding jig 24. This is a part that plays a role for pressing the component 2.
The insertion pin 32 is supported by the pin support member 33 in such a manner that the insertion pin 32 can be reciprocally displaced in the axial direction by inserting the pin body 32 a through the insertion hole 33 a of the pin support member 33. Moreover, the press part 32b is a site | part which contacts the insertion component 2, and is formed in the edge part of the pin main body 32a with the wear-resistant member.

  The protrusion 32c is a substantially bar-shaped portion that protrudes in a direction perpendicular to the axial direction of the pin body 32a at the end opposite to the end where the pressing portion 32b of the pin body 32a is formed. . The protrusion 32c is inserted into the cam groove 31b in a state where the insertion pin 32 is supported by the pin support member 33. Note that a roller or the like for reducing contact resistance with the cam groove 31b can be provided at the tip of the protrusion 32c.

  The pin support member 33 is a part for supporting the insertion pin 32 so as to be reciprocally displaceable in the axial direction, and includes an insertion hole 33 a for inserting the insertion pin 32. The pin support member 33 is fixed on the outer peripheral surface of the insertion pin support portion 22d of the rotary drum 22 so that the axis of the insertion hole 33a is parallel to the axis (axis B) of the drum shaft 22a. ing.

  With such a configuration, the insertion pin 32 supported by the pin support member 33 maintains a state in which the axis of the insertion pin 32 is parallel to the drum shaft 22a (axis B) as the rotary drum 22 rotates. However, it is configured to revolve around the insertion pin support portion 22d.

  Further, at this time, since the protrusion 32c inserted into the cam groove 31b is displaced along the cam groove 31b, the rotational force of the rotary drum 22 is converted into a stress that causes the insertion pin 32 to reciprocate in the axial direction by the cam mechanism 30. And transmitted to the insertion pin 32.

  As a result, the insertion pin 32 is revolved around the insertion pin support portion 22d as the rotary drum 22 rotates, so that the insertion pin 32 is axially centered in the direction parallel to the drum shaft 22a. It can be reciprocated in the direction. Further, the displacement position of the insertion pin 32 corresponds to the rotational phase of the rotary drum 22.

  Similarly to the work holding jig 24, the cylindrical cam 31 and the insertion pin 32 have a dedicated design according to the type of the parts, and each member 31 and 32 can be replaced. The component assembling apparatus 100 can easily cope with various types of component assembling.

Next, the component supply unit 40 will be described.
As shown in FIGS. 4 and 5, the component supply section 40 is a portion that is disposed substantially above the rotary drum 22 and in which a supply path 41 is formed. It plays the role of supplying 2.

  As shown in FIG. 5, the component supply unit 40 includes a plurality of supply paths 41a, 41b, and 41c having cross-sectional shapes that match the outer shapes of the cylindrical hollow component 1 and the columnar components 2a and 2a. The workpiece holding jig 24 is a simple mechanism that does not use a power source or the like by using the action of the parts 1, 2 a, 2 a held in the supply path 41 of the unit 40 falling downward by its own weight. The respective parts 1, 2 a, 2 a can be supplied. Moreover, the component supply part 40 shown to a present Example is set as the structure formed in the aspect which the supply path | route 41 meanders, By this, the increase in the number of components which can be hold | maintained in the component supply part 40 is aimed at.

As shown in FIG. 5, when the parts 1 and 2 discharged from the supply path 41 (that is, dropped downward) are in contact with the drum portion 22 b of the rotary drum 22, the parts 1 and 2 are transferred to the transfer path 25. It cannot enter, and it will be in the state which waits, without being transferred. On the other hand, only when the parts 1 and 2 are fitted into the work holding jig 24 and the height of the portion protruding from the outer peripheral surface of the rotary drum 22 becomes smaller than the size of the gap of the transfer path 25, the transfer path 25. The parts 1 and 2 are transported along
The components 1 and 2 held by the workpiece holding jig 24 are assembled by the action of the cam mechanism 30 while being transferred through the transfer path 25.

Next, the component discharge unit 50 will be described.
As shown in FIG. 5, the component discharge unit 50 is a part for discharging the assembled component 3 that has been assembled from the component assembling apparatus 100, and includes a discharge roller 51, a discharge rail 52, and the like. In the component discharge unit 50, the assembled component 3 that has been assembled is inherited from the rotary drum 22 by the discharge roller 51, and the assembled component 3 is dropped from the discharge roller 51 onto the discharge rail 52 by its own weight and discharged. And it is set as the structure which rolls the assembled component 3 along the inclination of the discharge rail 52 by the effect | action of its own weight, and guides it outside the components assembly apparatus 100.

  As described above, in the component assembling apparatus 100 according to the first embodiment of the present invention, the components 1 and 2 supplied from the component supply unit 40 are transferred by the rotary mechanism 20 and the components are moved by the cam mechanism 30. The assembled parts 3 are generated by assembling 1 and 2, and the assembled parts 3 are discharged from the parts discharging unit 50.

  Next, the assembling status of the assembled part 3 by the component assembling apparatus 100 according to the first embodiment of the present invention will be described with reference to FIGS. 10A to 14B, the casing 23 and the transfer path 25 are not shown for convenience of explanation.

  When the rotary drum 22 is in the rotational phase state (referred to as the first step) shown in FIG. 10A, the component holding recess 24a and the component holding groove 24b of the workpiece holding jig 24 are still in the cylindrical hollow parts. 1 and the insert part 2 (specifically, the cylindrical parts 2a and 2a) are not supplied, and the parts 1 and 2 face the casing 23 from the part supply unit 40 while being in contact with the rotating drum 22 that is rotating. It has become.

  At this time, as shown in FIGS. 10B and 10C, the insertion pin 32 is displaced to the position where the pressing portion 32b is farthest from the components 1 and 2 in accordance with the shape setting of the cam groove 31b ( That is, the insertion pin 32 is in the most shortened state with respect to the drum portion 22b).

  Next, the workpiece holding jig 24 (that is, the component holding recess 24a and the component holding groove portion 24b) until the rotation phase of the rotary drum 22 reaches the state shown in FIG. Passes through the contacts of the parts 1 and 2 with respect to the drum portion 22b. During this passage, each of the components 1 and 2 is discharged from the component supply unit 40 by dropping into the component holding recess 24a and the component holding groove 24b by its own weight. Thereby, each component 1 and 2 will be in the state hold | maintained by the component holding | maintenance recessed part 24a and the component holding groove part 24b of the workpiece holding jig 24. FIG.

  At this time, as shown in FIGS. 11 (b) and 11 (c), the insertion pin 32 is in the middle of being displaced in the direction in which the pressing portion 32b approaches the parts 1 and 2 according to the shape setting of the cam groove 31b. Is in a state.

  Each of the components 1 and 2 held by the component holding recess 24a and the component holding groove 24b of the work holding jig 24 is a drum portion viewed from the rotation center of the rotary drum 22 by the amount that fits into the component holding recess 24a and the component holding groove 24b. Since the protruding height to the outside of 22b becomes low, it can pass through the transfer path 25 formed by the inner peripheral surface of the casing 23 and the outer peripheral surface of the rotary drum 22. Therefore, the parts 1 and 2 are guided and transferred along the transfer path 25 by the rotation of the rotary drum 22.

  Further, the parts 1 and 2 to be kept in the parts supply unit 40 next to the parts 1 and 2 fitted in the part holding recess 24a and the part holding groove 24b cannot enter the transfer path 25, and the drum part 22b.
