The present invention relates to a ring riveting device of a heat dissipating negative electrode insulator, and more particularly, a ring rivet of a heat dissipating negative electrode insulator capable of automatically performing upper and lower riveting of a ring interposed on an inner circumferential surface of a hole into which a sleeve is inserted. The present invention relates to a setting device.

In general, as shown in FIG. 4, the heat dissipating cathode is provided with a heater B inside the cylindrical sleeve A, and an electron-emitting material C is coated on the top of the sleeve A. The cap D is covered and penetrated through the ceramic insulator E so as to be installed in the first electrode F. As shown in FIG.

And between the sleeve (A) and the insulator (E) there is a metal ring (G) fused to the sleeve (A), because the ring (G) is installed in a state that is simply inserted into the insulator (E) A riveting operation is necessary to extend the upper and lower ends of the ring G to prevent it from being separated from the insulator E.

5 is an exploded perspective view of the insulator E and the ring G of the heat dissipating cathode. In the related art, the ring G is inserted into the hole of the insulator E, and then placed on a jig, and a worker directly Repeated 2-3 times with a riveting operation.

As described above, since the riveting work of the ring is performed by hand, it takes a lot of time and effort, which is one factor that degrades workability.

The present invention is devised to solve the problems of the prior art as described above, the object of the present invention is to automatically perform the riveting of the ring inserted into the insulator ring rivet of the insulator for heat dissipation type negative electrode which can improve work The present invention provides a device.

In order to achieve the above object, the present invention provides an insulator supply portion formed by opposing one pair of channel members spaced apart from each other by a predetermined interval, and a guide extending perpendicularly from the channel member and having protrusions at ends. A stopper for fastening the pusher linearly reciprocating into the guide, a stopper for fixing the insulator transported by the feeder on the guide, and opposite sides of the ring axial direction of the insulator, the inclined surface being formed at the end. Provided is a riveting device for holding an expansion member.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of the riveting device of the present invention, reference numeral 1 denotes an insulator supply unit.

The insulator supply section 1 holds two channel members 2, 3, which are arranged oppositely and fixed in a floating posture by the support frame 4. As shown in FIG.

The channel members 2 and 3 are It is formed in the shape of a magnetic cross section so that the insulator E can be inserted, and these members 2 and 3 have a passage 5 in which the ring G of the insulator is located at a predetermined distance apart.

A guide 6 extends in the orthogonal direction at the lower end of the channel member 3, and the guide 6 forms a projection 6a at its end.

By this configuration, the insulator E located between the channel members 2 and 3 freely falls to the guide 6.

Feeding means 7 is disposed on the other side of the guide 6.

The feeding means 7 have a pusher 8 which is fixedly installed at the rod end of the cylinder 9 so as to linearly reciprocate along the guide 6.

The end of the pusher 8 is formed of an arc surface 8 'which can be in close contact with the outer circumferential surface of the insulator E.

The insulator E supplied from the insulator supply unit 1 is moved to the front of the projection 6a of the guide 6 by the pusher 8 to stop, and the stopped insulator E is a stopper installed vertically upward. 10) to maintain a floating posture.

The stopper 10 has the same configuration as the cylinder, and the pressing member 11 is locked by the hydraulic or pneumatic pressure to lock the insulator E.

In the axial direction of the ring G in the state in which the insulator E is stopped, a pair of riveting means 12 is arrange | positioned opposingly.

The riveting means 12 may use a cylinder, an actuator, or the like, and an extension member 14 having an inclined surface 13 is installed at the rod end to move forward.

In the riveting device of the present invention configured as described above, if a plurality of channels are inserted between the channel members 2 and 3 by inserting the ring G into the insulator E, the first insulator E is introduced in FIG. As shown by the dashed-dotted line, it is positioned in the guide 6 and the other insulators are deposited thereon.

In this state, when the cylinder 9 of the feeding means 7 moves forward, the pusher 8 pushes the insulator E while moving to the left as shown in the drawing.

By this action, when the insulator E conveyed along the guide 6 reaches just before the projection 6a, the forward operation of the cylinder 9 is first stopped, and the pressing member 11 of the stopper 10 is stopped. Lowering operation, press the insulator (E) to hold in a floating position.

When this series of actions is completed, a pair of riveting means 12 operate simultaneously to advance the expansion member 14 as shown in FIG.

Then the inclined surface 13 is pushed into the ring (G) to expand the ring (G) to be riveted.

When the riveting operation is completed, the expansion member 14 moves backward, the pressing member 11 of the stopper 10 rises, and the cylinder 9 moves forward to push the insulator E over the projection 6a. Transfer to the next process.

Although the above has been described with respect to the one-time riveting operation, since the riveting operation proceeds while the above-described series of operations are repeated repeatedly, it is possible to solve various problems caused by the conventional manual operation.
