Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for automatically inserting a cylindrical part into a body having a small clearance tolerance and a small depth hole with respect to the cylinder. .

Conventional structure and problems thereof Conventionally, for this type of insertion, the component 1 was checked as shown in FIG. 1, and the component 1 was inserted perpendicularly to the object 2 to be inserted. In this method, the position of the chuck 3 relative to the inserted object 2 must be controlled with great precision. Therefore, the chuck 3 itself needs to be rigid, making the device very large and expensive. Also, in this type of insertion, the second
By chamfering the end face of the component 1 or the inserted object 2 as shown in FIGS. 3 and 3, it is possible to make the machine precision rough. However, in this case, the design of the product itself will need to be changed.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks and is a device that achieves reliable insertion in a simple and inexpensive manner without changing the design of the product.

Structure of the Invention The cylindrical component insertion device of the present invention includes a chuck portion that holds a cylindrical component and is rotatable about an axis perpendicular to the direction of a hole into which the cylindrical component is inserted; a regulating part that holds the cylindrical part at a certain angle with respect to the direction and rotates the cylindrical part to stand upright with respect to the hole when a part of the cylindrical part is inserted into the hole of the inserted object; and a regulating part that holds the chuck part. and a transfer section that moves the chuck section in the insertion direction and supplies the cylindrical component to the position of the hole in the inserted object. The device has a mechanism for converting the inserted component into a device with a relatively rough positioning accuracy, so that the insertion can be performed reliably even if the positional accuracy of the inserted component is relatively rough, and the overall configuration can be simplified.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 9. FIG. 4 shows the state when the cylindrical component 1 is inserted into the hole of the inserted object 2. As shown in FIG. Reference numeral 4 denotes a chuck body, which is rotatably held in a chuck holding portion 6 by a shaft 5. The chuck holding portion 6 is held by a main shaft 7 on a bracket 8 so as to be movable up and down. 9
is a guide, 10 is a compression spring, and chuck holding part 6
It regulates the vertical movement of. The bracket 8 is fixed to the transfer device 11. 12 is a plate cam, which is fixed to the bracket 8. A cam follower 13 is fixed to the shaft 5 by a mounting plate 14. The cam follower 13 is pressed against the plate cam 12 by a tension spring 15. Reference numeral 16 is a hit, which regulates the height to which the chuck holding portion 6 can be lowered.

Next, the operation will be explained. When the chucked cylindrical part 1 is transferred to the upper part of the inserted object 2, the chuck holding part 6 and the bracket 8 are spread apart by a constant distance by the compression spring 10. At this time, the cam follower 13 is located below the plate cam 12, and the chuck body 4 is inclined with respect to the insertion direction (see FIGS. 5 and 6). Next, the transfer device 11
When the cylindrical part 1 is partially inserted into the inserted object 2 while being tilted, the chuck holding part 6 hits the cylindrical part 1.
6, the chuck body 4 completes its descent (see FIG. 7). Further, as the transfer device 11 continues to descend, the distance between the chuck holder 6 and the bracket 8 becomes narrower. At this time, the cam follower 13
2 and move upward on the chuck body 4.
rotates, and the cylindrical part 1 stands upright (Figs. 8 and 9).
(see figure). After this, the chuck opens and insertion is complete.

Effects of the Invention As described above, the present invention is an insertion device that tilts a cylindrical component at a certain angle from the insertion direction, partially inserts it into a hole of an inserted object, and then stands it upright. It can be inserted reliably even if the positional accuracy is relatively rough. Furthermore, since no special actuator is required to rotate the chuck, the structure is simple and inexpensive.
