Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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 Conventionally, for this type of insertion, as shown in FIG. 1, the component 1 is rotated and 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 high precision. Unfortunately, the chuck 3 itself needed to be rigid, making the device very bulky and expensive. Further, in this type of insertion, it is possible to make the mechanical accuracy rough by chamfering the end face of the component 1 or the inserted object 2 as shown in FIGS. 2 and 3. However, in this case, a design change of the Ai4 itself occurs.

OBJECTS OF THE INVENTION The present invention solves 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.

Composition of the Invention The present invention chucks a cylindrical part 7, includes a chuck part that is rotatable about an axis perpendicular to the insertion direction, a plate cam part that restricts rotational movement of the chuck part, and a cylindrical part that is inserted into an object. It is constructed by a transfer section that can move up and down to supply the material to the hole position, and the overall structure can be simplified.゛Description of an Embodiment Below, an embodiment of the present invention will be described based on FIGS. 4 to 9. FIG. 4 shows the state when the cylindrical component 1 is inserted into the hole of the inserted object 2. FIG. Reference numeral 4 denotes a chuck body, which is rotatably held by a chuck holding portion 6 by a shaft 5. The chuck holding part 6 is held by a main shaft 7 on a bracket 8 in a state where it can be moved downwardly. Reference numeral 9 represents a guide, and reference numeral 10 represents a compression spring, which restricts the vertical movement of the chuck holding portion 6. The bracket 8 is fixed to the transfer device 11. A plate cam 12 is fixed to the bracket 8. A cam follower 13 is fixed to the shaft 5 by a mounting plate 14. cam follower 1
3 is pressed against the plate cam 12 by a tension spring 15. Reference numeral 16 denotes a seat, which regulates the height at 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 top of the inserted object 2, the compression spring 1
0, the chuck holding part 6 and the bracket 8 are spread out at a constant interval. 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. 6 and 6). Next, the transfer device 11 descends, and when the cylindrical component 1 is partially inserted into the inserted object 2 while being tilted, the chuck holding part 6 hits the abutment 16, and the chuck body 4 completes its descent (7th (see figure).

When the transfer device 11 continues to descend further, the chuck holding section 6
and the distance between the brackets 8 becomes narrower. At this time, the cam follower 13 moves upward on the plate cam 12, the chuck body 4 rotates, and the cylindrical part 1 stands upright (the eighth
(see Figure 9). After this, the chuck opens and insertion is completed.

Effects of the Invention As described above, the present invention is an insertion device that tilts a cylindrical part 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. Since it does not require a special actuator to rotate the chuck, it is characterized by a simple structure and low cost.
