Description

The present invention relates to a fitting device for fitting two members.

Conventionally, as an example of a fitting device for fitting two members, there is, for example, Japanese Patent Application Laid-Open No. 2006-182427. As shown in FIG. 6, the container holder 14, the stopper stopper 15, and the container guide 16 are included. When the inner stopper 17 is plugged into the container opening 19 by the inner stopper knocker 15, the inner stopper 17, the container opening 19, and the inner stopper knocker 15 are held by the container guide 16, whereby the inner stopper 17 is Some were fitted into the opening 19 of the container 18.

However, in the fitting device for fitting these two members, the inner plug 17 and the opening 19 of the container need to be strongly held by the container guide 16, so that the inner plug 17 and the opening 19 of the container are damaged. was there. Further, before and after the inner stopper 17 is fitted into the opening 19 of the container, it is necessary to move the container guide 16 so as not to obstruct the conveyance of the inner stopper 17 and the container 18, so that extra power is required. At the same time, there is a problem that the fitting operation cannot be performed at high speed.

Another fitting device for fitting two members is, for example, Japanese Patent Laid-Open No. 7-032228. As shown in FIG. 7, the first jig unit 20, the second jig unit 21, the positioning means 22, and a base 24 that can be floated in the horizontal direction by a lift mechanism 23. The first jig unit 20 holds the first member 1, and the second jig unit 21 holds the second member 3, and the first member 1 and the second member 3 are fitted together. At the same time, the positioning means 22 adjusts the positions of the first jig unit 20 and the second jig unit 21, and at the same time the base 24, which can be floated in the horizontal direction by the lift mechanism 23, is fitted with slight movement in the horizontal direction. Some were raised in the direction and fitted.

However, in the fitting device for fitting these two members, the base 24 is fitted while being finely moved in the horizontal direction in accordance with the degree of sliding of the first member 1 and the second member 3, so that the two members In addition to the fitting direction, a force is applied in a direction perpendicular to the fitting direction, and the place where the first member 1 is held by the first jig unit 20 and the second member 3 are the second jig unit 21. There was a problem of damaging the parts held in the. Moreover, when the positioning accuracy of the first member 1 and the second member 3 before starting the fitting is low, the first member 1 and the second member 3 cannot be evenly fitted and the fitting operation is performed. There was a problem that could not be realized. Furthermore, in order to make the base 24 floatable in the horizontal direction by the lift mechanism 23, it is necessary to flow in air, which requires extra power and complicates the apparatus.

As another fitting device for fitting two members, there is, for example, Japanese Patent No. 3271146. As shown in FIG. 8, the loose insertion means 25 for loosely inserting the second member 3 into the first member 1 and the end surface 26 opposite to the fitting portion of the second member 3 are in contact with the axial center. There is a pressing means 27 that presses the end surface 26 in the fitting direction while moving in a circumferential direction at a position separated by a predetermined radius. First, the second member 3 is loosely inserted into the first member 1 by the loose insertion means 25. Next, the tip of the pressing means 27 moves in a circumferential direction at a position away from the axis by a predetermined radius while pressing the end surface 25 opposite to the fitting portion of the second member 3. The member 3 is slightly rotated while being swung, and the first member 1 and the second member 3 are fitted while being aligned.

However, in the fitting device for fitting the two members, there is a problem that the end surface 26 is damaged because the end surface 25 opposite to the fitting portion of the second member 3 is pressed unbalanced. . In addition, since the second member 3 is rotated and fitted with a swing motion, there is a problem of damaging the fitting portion. Further, when the accuracy of alignment between the first member 1 and the second member 3 before starting the fitting is low, the second member 3 is loosely inserted into the first member 1 by the loose insertion means 25. There was a problem that the fitting operation could not be realized. Furthermore, since it is necessary to move the mechanism for realizing the loose insertion means 25 so as not to disturb the conveyance of the first member 1 and the second member 3 before and after the fitting, extra power is required. At the same time, there is a problem that the fitting operation cannot be performed at high speed.

Another fitting device for fitting two members is, for example, Japanese Patent Laid-Open No. 9-272025. As shown in FIG. 9, it has the positioning arm 29 which controls the position of the member to fit with the means 28 which automatically measures the three-dimensional position of a fitting part. When two members are fitted, a positioning arm that controls the position of the member to be fitted based on the three-dimensional position data measured by the means 28 for automatically measuring the three-dimensional position of the fitting portion. There were some which were fitted while being moved appropriately by 29.

However, in the fitting device for fitting these two members, the means 28 for automatically measuring the three-dimensional position of the fitting portion is complicated, so that the whole device is complicated and expensive. Further, since it is necessary to move the fitting member by controlling the position of the member to be fitted appropriately by the positioning arm 29 by measuring a minute change in the position, extra power is required. There was a problem that control took time and the fitting operation could not be performed at high speed.
