Description

[Detailed description of the invention] The purpose of this invention is to make it possible to easily insert a flexible body such as rubber having an outer frame size that is approximately the same size as the hole into a hole in a product made of thin plate. This invention relates to a flexible body insertion device.

Conventionally, when inserting a flexible body such as rubber into a circular or irregularly shaped hole in a product made of thin plate, the work was done manually, which not only resulted in poor work efficiency but also caused curling and misalignment of the periphery of the flexible body. It was occurring.

The present invention has been devised to deal with such problems, and will be explained below based on drawings showing an example of implementation.

The embodiments shown in FIGS. 1 to 4 relate to micromotor assembly.

In FIGS. 1 to 4, reference numeral 1 denotes a cylindrical case made of a thin plate, and a circular hole 2 is formed in the upper end of the case.

Reference numeral 3 denotes a flexible body made of rubber or the like, in the center of which is formed a circular hole 5 into which the central protrusion 4a at the upper end of the micromotor 4 is fitted, and on the periphery of the circular hole 5 is an upward protrusion. 6 is formed in a ring shape.

The outer diameter of this protrusion 6 is formed to be approximately the same as the inner diameter of the circular hole 2.

7 is a recess 7 into which the lower end of the micromotor 4 is fitted.
The receiver that has the letter a on the upper surface and that fits into the lower end opening of the case 1 is a stand.

The flexible body 3 is designed such that its protrusion 6 fits into the circular hole 2 of the case 1 from the inside.

The present invention is a device for inserting the flexible body 3 into the circular hole 2 of the case 1 when assembling the case 1, the flexible body 3, the micromotor 4, and the support 7.
a retractable chuck 8 that grips and holds the body of the micromotor 4; a presser pin 9 that presses from above the protrusion 6 of the flexible body 3 fitted onto the central protrusion 4a of the micromotor 4; and the presser pin 9. It is equipped with a spring 10 that urges the .

The lower end of the presser pin 9 is formed into a cylindrical shape, and the lower end cylindrical part 11 can be fitted into the circular hole 2 of the case 1 from above, and the wall thickness of the lower end cylindrical part 11 is as follows. The protrusion 6
The outer corner portion 11a of the lower end cylindrical portion 11 is cut into a tapered shape.

Therefore, the circular hole 2 of the case 1 can be inserted using the insertion device of the present invention.
When inserting the flexible body 3 into the case 1, the case 1 is first gripped and held by the chuck 8 with the lower cylindrical portion 11 of the presser pin 9 inserted into the circular hole 2 of the case 1, as shown in FIG.

The lower end of the micro motor 4 is located in the recess 7 of the support 7.
a, and is located directly below the case 1 and coaxially with the case 1, with the flexible body 3 externally fitted onto the central protrusion 4a.

When the apparatus is lowered from the state shown in FIG. 2 by a driving means such as a cam, the case 1 is held over the micromotor 4 while being gripped by the chuck 8.

At this time, the lower end cylindrical portion 11 of the presser pin 9 comes into pressure contact with the upper surface of the flexible body 3, and the outer corner portion 6a of the protrusion 6 of the flexible body 3 is deformed into a small diameter shape by the tapered outer corner portion 11a. (See Figure 3).

Thereafter, as shown in FIG. 4, with the chuck 8 open, the case 1 is lowered as shown by the two-dot chain line in FIG. 3 using the presser pin 9 as a guide. Since it has a small diameter, the circular hole 2 of the case 1 can easily fit into the protrusion 6 of the flexible body 3.

After that, when the device is raised by a driving means such as a cam,
The flexible body 3 is released from the presser pin 9 and returns to its original shape by its own elasticity, and the flexible body 3 and the circular hole 2 of the case 1 are completely fitted.

Although the flexible body 3 is inserted into the circular hole 2 of the cylindrical case 1 in FIGS. 1 to 4, it can be formed into flat thin plate products 12 and 13 as shown in FIGS. 5A and 5B. It is also possible to insert disk-shaped and square plate-shaped flexible bodies 16 and 17 into the rectangular hole 14 and circular hole 15, respectively.

The flexible body insertion device of the present invention can be implemented as described above, and the flexible body can be pressed and deformed by the presser pin to easily fit into the hole of the thin plate product, and at this time, the flexible body can be easily fitted into the hole of the thin plate product. The product moves toward the flexible body using the presser pin as a guide, and the fitting between the hole of the product and the flexible body is performed smoothly.

Furthermore, the present invention eliminates the problems of conventional methods such as curling up and misalignment when inserting a flexible body, and allows the flexible body to be mechanically inserted into a hole in a thin plate product, greatly improving work efficiency.
