Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a supply tool for a holed component such as a washer.

<Prior art> Conventionally, as a means for manually inserting a holed part (for example, a washer or an O-ring) aligned by a part feeder into a supply site, a) use commercially available tweezers A means to hold it and insert it into the supply site.

B) A means for sucking the perforated parts one by one using a vacuum suction pen and inserting them into the supply site.

And so on.

<Problems to be Solved by the Invention> However, with the above-mentioned conventional means, when tweezers are used, it is difficult to hold the component with holes, and the component easily falls during supply.

When a suction pen is used, it is difficult to see the holes of the part with holes, so it takes time to surely insert these holes into the supply site.

Therefore, there is a problem in that workability and productivity are reduced due to supply mistakes and longer working time.

<Means for Solving the Problems> The present invention eliminates the above-mentioned problems, provides a supply tool for a perforated component that is excellent in workability and productivity, has no supply error, reduces work time, The purpose is to

That is, a holder made of a cylindrical body, a cap attached to the tip of the holder to form a through hole, a tapered tapered split pin inserted in the through hole, and the split pin are attached. A push rod inserted into the holder, a spring provided between the cap and the push rod, a stopper portion formed on the push rod, and the push rod loosely inserted to the rear of the holder. It is characterized by comprising a stop lid attached to the end portion and a knob provided at the rear end portion of the push rod.

<Operation> The device for supplying a component with a hole according to the present invention having the above-described configuration includes: i) A tip split pin is fitted into the hole of the component with a hole, and the repulsive force of the tip split pin is used to press from inside the hole; Since the parts with holes are held, the parts with holes are prevented from being missed or dropped during supply.

ii) Since the tip split pin is fitted into the hole of the holed component, it is easy to align the tip of the tip split pin with the feed site, and the tip split pin serves as a guide to stabilize the holed component at the feed site. Supply.

<Embodiment> An embodiment of the present invention will be described with reference to the drawings.

In a supply tool 1 for a holed component shown in FIG. 1, a holder 2 is made of a cylindrical body, and a cap 3 is screwed onto a tip portion of the holder 2.

A through hole 4 is provided in the cap 3. Further, inside the cap 3, a spring seat 5 and a pin receiving portion 6 for receiving a collar of a tip split pin described later are provided. Further, the outer shape of the cap 3 is tapered.

A push rod 7 is inserted inside the holder 2.
A tip split pin 8 is attached to the tip of the push rod 7. Further, a step portion is provided on the front end side and the rear end side of the push rod 7, and a spring seat 9 is formed on the step portion on the front end side.
A stopper portion 10 is formed on the step portion on the rear end side.

The tip split pin 8 has a tapered shape with a rounded tip, and a groove 11 divides the tip into a plurality of pieces. A collar 12 is provided at a predetermined position on the outer circumference of the tip split pin 8. Furthermore, the tip split pin 8 is formed of an elastic body. The tip split pin 8 is inserted into the through hole 4 so as to be inserted therethrough.

Also, the spring seat 5 of the cap 3 and the spring seat 9 of the push rod 7
A compression coil spring (spring) 13 is provided between and.

Therefore, even if the tip tip split pin 8 is projected from the through hole 4, it is automatically returned to the inside of the through hole 4 by the repulsive force of the compression coil spring 13.

Further, at the rear end of the holder 2, the push rod 7 is loosely inserted and a stopper lid 14 for receiving the stopper portion 10 is screwed. A knob 15 is provided at the rear end of the push rod 7.

In order to apply the above-described supply device 1 for a holed component to a holed component having various hole diameters, the tip split pin 8 is detachably attached to the push rod 7 by screwing. Further, a cap 3 having a through hole 4 matching the diameter of the tip split pin 8 is provided so as to be attachable to the holder 2 by screwing. Accordingly, it is desirable that the tip split pin 8 can be replaced with a pin corresponding to the hole diameter of the holed component.

Next, a method of supplying a perforated component using the supplying device 1 configured as described above will be described.

First, the tip split pin 8 is replaced with a pin having a maximum diameter of the tip cracked portion which is larger than the hole diameter of the perforated component to be supplied and has a diameter such that the tip cracked portion can fit into the hole of the perforated component. . At the same time, the cap 3 is replaced with a cap having a through hole 4 into which the tip split pin 8 can be inserted.

Next, the knob 15 is pushed to compress the compression coil spring 13 via the push rod 7 and the tip split pin 8 is projected out of the through hole 4.

At this time, the collar 12 provided on the front split pin 8 contacts the pin receiving portion 6 to prevent the front split pin 8 from over-projecting.

Then, as shown in FIG. 2 (a), the protruding tip split pin 8 is fitted into the hole 21 of the washer (part with hole) 20.

At this time, the pins 8a and 8b are pressed toward the groove 11 side. That is, the hole 21 is pressed from the inside by the repulsive force of the elastic pins 8a and 8b, and the washer 20 is held by the tip split pin 8.

As shown in Fig. 2 (b), attach the washer 20 to the projection of the bush 22.
In order to insert it into 23, align the tip of the tip split pin 8 with the top of the projection 23, and project the projection 23 and the tip split pin 8.
Align with the axial direction of.

Then, the force pushing the knob 15 (shown in FIG. 1) is gently alleviated, and the tip split pin 8 is inserted into the through hole 4 of the cap 3 as shown in FIG. (Shown in Figure 1)
Use the repulsive force of to return.

At this time, the tip split pin 8 fulfills a guide function, and the tip end of the cap 3 contacts the washer 20, and the washer 20 is pushed out from the tip split pin 8 and inserted into the protrusion 23.

In the above-described device 1 for supplying a holed part, the knob 15 needs to be continuously pressed while the holed part is supplied. Then, when the knob 15 is pushed once, the tip split pin 8 projects from the through hole 4 and is held in that state. Therefore, it is possible to add a one-way lock mechanism in which the tip split pin 8 returns to the inside of the through hole 4 when the knob 15 is pushed again.

<Effect of the Invention> As described above, according to the present invention, it is possible to easily and surely hold the component with holes.

Since the tip split pin serves as a guide, the part with holes can be reliably inserted into the supply site.

Therefore, it is possible to obtain an excellent effect that supply mistakes are reduced, work time can be shortened, and workability and productivity can be improved.
