DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a holding device for a circular object such as a terminal type aluminum electrolytic capacitor.

2. Description of the Related Art Conventionally, when a terminal type aluminum electrolytic capacitor (hereinafter referred to as a capacitor) was transported in an upright position, a holding device as shown in FIGS. 5 and 6 was used. That is, this holding device was constructed as follows. That is, four support pins 2 are provided at predetermined intervals on the top surface of the device main body 1, and a convex portion 4 having a diameter smaller than the diameter of the insulating plate 3 is provided at the center of the top surface.
is provided to form a fitting part 6 for inserting a terminal type aluminum electrolytic capacitor (hereinafter referred to as a capacitor) 6, and a groove part 7 is provided at a predetermined position on the side surface of the device body 1, and a first rotation A presser lever 8 that is swingably supported by a support shaft 8a is fitted.

Further, an L-shaped lock lever 10 is inserted into a space e continuous to the lower part of the groove 7, and is swingably supported by a second rotation support shaft 10a. The presser lever 8 and the lock lever 10 are provided at a position such that the lower end portion 8b of the presser lever 8 is supported downward by the lower end portion iob of the lock lever 10, and a convex portion 100 provided on the upper portion of the lock lever 1o. A compression spring 11 is provided between the holding lever 8 and a convex portion 80 provided at the lower part of the holding lever 8, so that both the levers 8 and 1o repel each other. In this case, the presser lever 8
Since the first rotational support shaft 8& is located above the compression spring 11, the tip 8d of the presser lever 8 is not pushed in the direction of the central axis of the device body 1. Therefore, the tip of the presser lever 8 In the part 8d, the capacitor 5 is attached to four support pins 2.
The capacitor 6 is pressed and held when the capacitor 6 is inserted into the fitting portion 6 formed between the capacitors 6 and 6. In addition, since the lower end 1ob of the lock lever 1o is rotated so as to be pushed upward by the compression spring 11, the lower end 8b of the holding lever 8 is moved against the spring force of the compression spring 11 to
When pushed in the central axis direction, the lower end 8b of the presser lever 8 engages with the engagement stepped portion 10d of the lock lever 10, and the presser lever 8 is locked in a biased state and expanded.

Then, by inserting the capacitor 5 into the fitting part 6 formed between the four support pins 2 and pushing down the lower end 10b of the lock lever 10, the lower end 8b of the presser lever 8 is moved to the engaging stepped part 10c. to remove it from the presser lever 8.
is opened, and the tip 8C of the holding lever 8 presses and holds the capacitor 6 by the force of the compression spring 11.

In addition, when performing insulation coating work on the capacitor 6 using this holding device, as shown in FIG. The covered capacitor 6 is connected to the terminal section 51 between the four support pins 2.
Insert with L facing up.

In this case, since the diameter of the convex portion 4 is smaller than the diameter of the capacitor 6, the insulating tube 12 can be placed under the convex portion 4. When the device main body 1 holding the capacitor 6 in this manner is carried into the furnace and the capacitor 6 is coated,
Since the insulating tube 12 hangs down to the bottom of the convex part 4, even if the insulating tube 12 is heated and shrunk, the terminal part Sa and the convex part 4 are not covered, and only other necessary parts are completely covered. It was to be done.

Problems to be Solved by the Invention However, since the conventional holding device described above has a structure in which four support pins 2 are fixed to the upper surface of the device main body 1, The diameter of the fitting part 6 is constant υ, therefore.

The capacitor 6 that is inserted into the fitting part 6 can only be used with this holding device if it has a fixed outer diameter. Several types of holding devices with portions 6 of different diameters were prepared.

In view of these problems, the present invention is capable of reliably holding circular objects such as several types of capacitors with different outer diameters with a single holding device, and can also be processed and inspected in various processes without changing them. The object is to provide a holding device for a circular object.

Means for Solving the Problems In order to solve the above problems, the device for holding a circular object of the present invention includes a device main body having a plurality of rocking bodies each having one end pivotally supported and swingably disposed; A rotating body rotatably supported by the device main body via the rocking body, and a plurality of clamping pins each fixed to the other end of the plurality of rocking bodies and clamping a circular object. The holding pin passes through a plurality of elongated holes provided in the rotating body, and the rotating body is arranged in a direction that constantly reduces the diameter of a fitting portion of a circular object formed by the plurality of holding pins. The rotation of the rotating body causes the plurality of clamping pins to move within the elongated hole, thereby increasing the diameter of the fitting part of the circular object formed by the plurality of clamping pins. It is something.

Effects According to the above structure, when the rotating body is rotated, the plurality of clamping pins move in the elongated hole against the force, and thus the structure is made up of the plurality of clamping pins. Since the diameter of the fitting part of a circular object varies widely, several types of circular objects such as capacitors with different outer diameters can be reliably held with one holding device. Various processes and inspections can be performed while holding the device.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 4, reference numeral 21 denotes a cylindrical device main body, and four rocking bodies 22 are arranged on the upper surface of the device body 21, and one end of each of the rocking bodies 22 is attached to a pin.
It is pivoted by 3. Further, in the main body 21 of the apparatus, a disk-shaped rotating body 24 is rotatably supported on a central shaft 25, and this rotating body 24 is located above the rocking body 22. A clamping pin 26 is fixed to the other end of each of the four swinging bodies 22, and the four clamping pins 26 are passed through four elongated holes 27 provided in the rotating body 24. The rotating body 24 is made to project upward.

Further, an operating knob 28 for rotating the rotating body 24 is provided on the side surface of the rotating body 24. Furthermore, rotating body 2
A circular convex portion 29 is provided on the upper surface of the central portion of the rotating body 24 so as to correspond to the central axis 25 of the rotating body 24. It constitutes a fitting portion of a capacitor (hereinafter referred to as a capacitor) 30.

The four clamping pins 26 protruding above the rotating body 24 are each provided with a notch 31, and the telescopic spring 32 is attached to the four clamping pins so that the telescopic spring 32 is hooked to the notch 31. It is wound around the outside of 26. The elastic spring 32 is always biased in a direction to reduce the diameter of the fitting portion of the capacitor 30 formed by the four holding pins 2e.

In the above configuration, the holding operation of the capacitor will be explained first. FIG. 3 shows that the four clamping pins 2 are
6 shows the state in which the diameter of the capacitor fitting part 6 is at its smallest. In this case, the four clamping pins 26 are inserted into the four elongated holes 27 provided in the rotating body It is located at point a. And in this state click operation knob 2
8, when the rotating body 24 is rotated clockwise, that is, in the direction of the arrow, four elongated holes 27 are formed as shown in FIG.
The four rocking bodies 22 also rotate clockwise about the pins 23 as a result. In this case, as the four rocking bodies 22 rotate clockwise, the four clamping pins 26 fixed to the other ends of the four rocking bodies 22 move against the spring force of the elastic spring 32. It moves relatively within the four elongated holes 27 and expands the elastic springs 32 wound around the outside of the four clamping pins 26. In this case, as shown in FIG. 4, when the four holding pins 26 are located at point b of the long portion 27, the diameter of the fitting portion of the capacitor is the largest. The four holding pins 2
When a capacitor with an outer diameter smaller than the diameter of the fitting part M is inserted into the fitting part M of the capacitor configured as shown in 6,
Since the telescopic spring 32 has a spring force that tends to return to the state shown in FIG. 3, the four clamping pins 26 return until they abut against the outer wall of the capacitor. When the four clamping pins 2e come into contact with the outer wall of the capacitor, the contact state is maintained by the spring force of the expansion/contraction spring 32, so that the capacitor is reliably held by the four clamping pins 2e.

In this way, the diameter of the fitting part of the capacitor can be freely changed within the range from point a to point b of the long part, so several types of capacitors with different outer diameters can be used in one holding device. It can be held securely.

Next, the working steps performed using the holding device of the present invention will be explained. That is, when performing insulation coating work on the capacitor 30 using this holding device, as shown in FIG. Insert the capacitor 3o between the four holding pins 26 with the terminal portion 30& facing upward. In this case, since the diameter of the convex portion 29 is smaller than the diameter of the capacitor 30, the insulating tube 34 can be placed under the convex portion 29. When the device main body 21 holding the capacitor 3o in this manner is carried into a furnace and the capacitor 3o is coated, the insulation tube 34 hangs down to the bottom of the protrusion 29, so the insulation tube 34 is heated and shrunk. Even if the terminal part 30
The portions a and the convex portion 29 are not covered, and only other necessary portions are completely covered.

Then, if the holding device is transported to the inspection room with the capacitor 3o that has been covered with insulation as it is, the leakage part 3
Since 0& protrudes from the top, it can be easily brought into contact with the test contacts of the test device, and thereby the characteristics can be easily tested without transferring the capacitor 3o to another holding device.

In the above embodiment, each of the four clamping pins 2e protruding above the rotating body 24 is provided with a notch 31, and the telescopic spring 32 is hooked onto the notch 31. 32 is wound around the outside of the four clamping pins 26, so that the elastic spring 32 constantly rotates the diameter of the fitting portion of the capacitor, which is formed by the four clamping pins 26, to a smaller diameter. Although the explanation has been given on a device that biases the moving body 24, the mounting position of the telescopic spring 32 is not limited to the mounting position shown in this one embodiment, and may be mounted on other parts. Furthermore, this biasing force is not limited to the expansion and contraction spring; in essence, the rotating body is biased in a direction that constantly reduces the diameter of the fitting part of a circular object such as a capacitor, which is made up of a plurality of clamping pins. It should be configured as follows.

Furthermore, in the above embodiment, a single cylindrical terminal type aluminum electrolytic capacitor is held, but the present invention is not limited to this capacitor.
For example, it can be applied to holding a cylindrical pond or a circular object.

Effects of the Invention As is clear from the description of the embodiments above, in the holding device for a circular object of the present invention, as the rotating body rotates, the plurality of clamping pins move within the plurality of elongated holes provided in the rotating body. Since the diameter of the fitting part of the circular object made up of multiple clamping pins is increased, it is possible to securely hold circular objects such as several types of capacitors with different outer diameters with one holding device. For example, if the holding device holds the capacitor and transports it into a furnace where insulation coating is performed, insulation coating using an insulating tube can be performed. In addition, even if an inspection is to be performed after this insulation coating work, if the capacitor is transported as is to the inspection room, the inspection can be easily carried out without having to transfer the capacitor.
It is possible to reduce the incidence of operational errors that occur when transferring capacitors, and as a result, the yield of products can be improved. It is also easy to maintain and manage the system.
