CONSTITUTION: A depressing sleeve 6 for depressing a plate member P is provided so as to make it freely slidable on a force-fitting punch body 1 that is driven and vertically moved by a drive mechanism. In addition, this depressing sleeve 6 is provided with a holding sleeve 10, which can be pulled out against a friction force, projectingly so as to be picked at the tip end normally; then, this holding sleeve 10 is pulled out with fingers, so that a rod-shaped member L is held with its tip, then in the state of surely holding the rod-shaped member L by operating the force-fitting punch body 1, the member L is safely assembled into a planar member W.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling apparatus for parts used when vertically assembling a rod-shaped member on the surface of a plate-shaped member.

[0002]

2. Description of the Related Art For example, a rod-shaped member L is erected on one surface of a plate-shaped member W as shown in FIG. In order to do so, a device is required that allows the rod-shaped member L to be inserted into the axial center portion and lowers the press-fitting punch.

However, in such an assembling apparatus, as in the case of a general press work, from the viewpoint of safety, it is impossible to put a hand directly under the press-fitting punch while the press-fitting punch is being lowered. It is difficult to lower the press-fitting punch while the rod-shaped member L is stably erected on the rod-shaped member W. Therefore, even a slight vibration causes the rod-shaped member L to fall down, so that these members are There are many problems such as damage caused by press-fitting punches.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its object is to:
It is an object of the present invention to provide a device for assembling a safe component, which is capable of stably holding a rod-shaped member and caulking it to a plate-shaped member.

[0005]

That is, the present invention relates to a device for assembling parts for achieving the above object,
A sleeve member that inserts and holds the rod portion of the rod member is attached to the axial center portion of the press-fitting punch body that is vertically moved by being driven by the drive mechanism so that the lower end part of the rod member always projects below the press-fitting punch body. The frictional force is retained, and the frictional force is overcome to be retained so that the frictional force can be pulled out.

[0006]

EXAMPLES Examples of the present invention will be described below. Each of the drawings shows an embodiment of the present invention.

In the press-fitting punch main body shown by reference numeral 1 in the drawing, a pressing sleeve 6 for pressing a plate member P, which will be described later, and a holding sleeve 10 for inserting and holding a rod portion of a rod-shaped member L are provided in the axial center portion thereof. Are respectively slidably mounted, and the cylindrical lower end portion of the press-fitting punch main body 1 is configured as a punch 2 which acts on the plate-shaped member W and caulks the plate member P.

On the other hand, the above-mentioned pressing sleeve 6 is always urged downward by the coil spring 3 interposed between the pressing sleeve 6 and the press-fitting punch main body 1 so that the axial center portion 4 of the press-fitting punch main body 1 is pressed. The lower end surface is attached to the plate member P when caulking is stopped.
And is configured as a pressing surface 7 for vertically holding the rod-shaped member L by acting on.

On the other hand, the above-mentioned holding sleeve 10 is slidably attached to the inside of the pressing sleeve 6 via an O-ring 11 fitted in a groove 11 on the outer periphery of the upper end while being held by frictional force. In addition, the ring 12 provided on the outer periphery of the upper end and the inner surface of the upper end of the pressing sleeve 6 are always so arranged that the tip thereof projects downward from the lower end of the pressing sleeve 6 by its own weight, that is, by a length that can be pinched with a finger. The taper portion 8 provided is configured to prevent frictional contact.

The holding sleeve 10 is provided with a shaft hole 13 at the center of its axis so that the rod portion of the rod-shaped member L can be easily inserted therein. A taper 14 that guides the insertion is formed.

In order to assemble the rod-shaped member L to the plate-shaped member W using the assembling apparatus constructed as described above, first, the head h is placed downward in the central recess provided in the plate-shaped member W. The member L is erected, and then the section L is placed on the head h.
The plate member P is placed together with the shape ring r and the O ring O.

Then, under this condition, as shown in FIG. 1, the press-fitting punch main body 1 standing by immediately above the rod-shaped member L is held at a lower end thereof by projecting about 1 cm. Pick the sleeve 10 with your fingers and attach it to the O-ring 12
Of the rod-shaped member W while resisting the frictional resistance of the rod-shaped member W, and the tip of the rod-shaped member W is slightly fitted to the rod-shaped member W as shown by the chain double-dashed line in the figure. Hold.

Then, in this state, a switch (not shown) is operated to lower the press-fitting punch body 1, and first,
The holding sleeve 10 contacts the plate member P, and then,
The pressing sleeve 6 descending so as to take in the holding sleeve 10 comes into contact with the plate member P, and finally,
While the press-fitting punch main body 1 compresses the coil spring 3 and presses the pressing sleeve 6 against the plate member P strongly, the press-fitting punch main body 1 descends to the state shown in FIG.
By caulking the peripheral edge of the plate member P of the plate member W,
Combine the whole into one.

When the press-fitting punch main body 1 starts to rise next after completing a series of assembling operations in this way, first, the pressing sleeve 6 is projected to the lower end of the press-fitting punch main body 1 by the urging force of the coil spring 3. Then, the holding sleeve 10 whose rear end is located in the tapered portion 8 of the pressing sleeve 6 descends by its own weight to the position where the O-ring 12 again comes into frictional contact with the pressing sleeve 6, and becomes the state shown in FIG. To return to the standby position for the next assembly. In the above-described embodiment, the O-ring 12 does not come into frictional contact with the upper end of the pressing sleeve 6 so that the holding sleeve 10 is always projected below the press-fitting punch body 1 to the extent that it can be pulled out with a finger. Although the taper portion 8 is provided, a weak coil spring may be interposed in this portion so that the lower end of the holding sleeve 10 is constantly protruded downward by the biasing force of this spring.

[0015]

As described above, according to the present invention, a support sleeve for supporting a rod-shaped member is always provided at the tip of the support sleeve at the axial center of a vertically moving press-fitting punch body driven by a drive mechanism. Since the rod member is held with a frictional force so as to project downward and is held so that it can be pulled out by overcoming the frictional force, the rod member is pulled out before starting the assembling operation by pulling out the holding sleeve below the press-fitting punch body. Since it can be held by the support sleeve, the plate-shaped member and the rod-shaped member of this kind can be assembled safely and reliably.
