Example

The present invention is provided inside the pipe P inserted in the mounting hole W1 of the warmer W and presses the inner side surface of the pipe P toward the mounting hole W1, (100) which catches the movable member (P).

4a, the apparatus 100 includes a hollow variable housing 120 disposed inside the pipe P, and a hollow housing 120 disposed inside the variable housing 120. [ (Not shown).

At this time, the pressing head 130 moves inside the variable housing 120 and deforms a part of the variable housing 120 in the direction of the pipe P.

That is, as shown in FIG. 4A, the pressing head 130 moves in the downward direction in the drawing so that a part of the variable housing 120 is deformed toward the pipe P side (left and right direction in the drawing).

As a result, the deformable housing 120 presses the inner surface of the pipe P so that the pipe P is closely attached to the mounting hole W1 and caulked.

Conventionally, the upper mold was caulked by hitting the pipe as described above.

In such a conventional technique, the lower mold is disposed on the bottom surface of the bead formed on the pipe, and the upper mold is disposed on the upper surface of the pipe, so that the bead is broken and the quality is deteriorated.

In addition, since the protrusion is formed on the outer surface of the upper mold to form a groove in the pipe, the pipe is broken and a quality defect occurs.

The present invention solves this problem. As described above, the pressure head 130 is moved inside the variable housing 120 to deform the variable housing 120 so that the pipe P is pressed in the direction of the mounting hole W1, So that the pipe P is caulked, so that beads are not needed and there is no risk of breakage of the bead.

In addition, the pressing head 130 of the present invention is not provided with protrusions as described above, so that no recess is formed in the pipe, thereby preventing damage to the pipe, thereby preventing quality deterioration.

Meanwhile, in the present invention, as described above, the variable housing 120 is deformed by the movement of the pressing head 130, but the variable housing 120 may have various shapes. However, as shown in FIGS. 4 and 5, The variable housing 120 has a hollow cylindrical housing main body 121 and another hollow cylindrical shape formed at one end of the housing main body 121. The flexible housing 120 is in contact with the pressing head 130, And a movable piece 122 having a hollow cylindrical shape which is deformed in the direction of the pipe P by a spring.

The movable piece 122 is deformed in the direction of the pipe P by the movement of the pressing head 130 so that the pipe P is pressed in the direction of the mounting hole W1, .

At this time, the movable piece 122 includes a vertical part 122-1 disposed in the same direction as the housing body 121 and contacting the pressing head 130, a vertical part 122-1 And a horizontal portion 122-2 which is disposed between the housing main body 121 and the housing main body 121 in a horizontal direction and supports the bottom surface of the warmer W in which the pipe P and the mounting hole W1 are formed.

That is, when the pressurizing head 130 moves downward in the state that the pipe P and the warmer W are supported by the horizontal part 122-2, the vertical part 122-1 is deformed At this time, the vertical portion 122-1 is deformed and presses the inner side surface of the pipe P in the outer direction, that is, the direction in contact with the mounting hole W1.

As a result, the pipe P is pressed and caulked to the mounting hole W1 side by this action.

4A, the outer side of the vertical portion 122-1 of the movable piece 122 is disposed parallel to the inner side surface of the pipe P, as shown in FIG. 4A, And the inner side of the vertical part 122-1 may have a shape in which the thickness of the pressing part 130 increases as the pressing head 130 moves.

That is, in the embodiment shown in FIG. 4A, the pressing head 130 moves in the downward direction in the drawing. In this case, the inside of the vertical part 122-1 is a shape in which the thickness increases in the downward direction in the drawing .

At this time, the pressing head 130 may have a shape in which the radius decreases toward the moving direction of the pressing head 130.

With the configuration of the pressing head 130 and the movable piece 122 having such a shape, the pressing head 130 moves in the downward direction in the drawing, and the movable piece 122 is moved in the direction of the pipe P, that is, And the deformed movable piece 122 presses the inside of the pipe P in the direction of the mounting hole W and is eventually caulked.

The diameter d0 of the mounting hole W1 and the outer diameter d2 of the movable piece 122 after deformation and the thickness t of the pipe P of the movable piece 122 satisfy the following equations ].

[Equation 1]

d0 < d2 + 2t

That is, since the movable piece 122 is deformed by the movement of the pressing head 130, the outer diameter d2 of the movable piece 122 increases.

Therefore, when the diameter of the movable piece 122 after the deformation is added to the thickness 2t of both sides of the pipe P, the diameter of the mounting hole W1 should be larger than the diameter of the mounting hole W1.

The diameter of the movable piece 122 after deformation plus the thickness 2t of both sides of the pipe P is larger than the diameter of the mounting hole W1 so that the pipe P is inserted into the mounting hole W1, And is caulked.

As described above, in the present invention, the pressurizing head 130 moves in the variable housing 120 to deform the variable housing 120. In FIGS. 4A and 4B, when the pressurizing head 130 is moved in the direction of the warmer W, 4C, the pressing head 130 is moved in the upper direction of the drawing, that is, in the upper direction of the warmer W, as shown in FIG. 4C, .

In this case, the outer side of the vertical part 122-1 is disposed parallel to the inner side surface of the pipe P, but the inside of the vertical part 122-1 is the same as the above- In which the thickness is reduced toward the bottom direction of the bottom surface.

In the case of the pressing head 130, the radius of the pressing head 130 increases as the pressing head 130 moves.

With this configuration, even when the pressing head 130 moves in the upward direction in the figure, the variable housing 120 can be deformed and the pipe P can be caulked to the mounting hole W as described above.

Meanwhile, as described above, the variable housing 120 of the present invention is deformed in accordance with the movement of the pressing head 130, and the cut-away portion C is formed in the variable housing 120 so as to be more smoothly deformed It is possible.

The cut-away portion C may be formed in a slit shape having a predetermined width as shown in FIG. 3, and the cut-away portion C may be formed long in the height direction of the variable type housing 120.

Also, the incision reduction (C) may be formed in a plurality of the incisive incisions (C) spaced apart from each other by a predetermined distance in the circumferential direction of the variable housing (120).

5, four cut-outs C are formed to divide the movable piece 122 and the housing body 121 into four parts, and then the four divided movable pieces 122 It is possible to pressurize the inside of the pipe P as described above.

It is a matter of course that this is merely an example for explaining the present invention. Even if the variable housing 120 has a different shape as long as the variable housing 120 is deformed so as to press the inner side of the pipe P It is of course within the scope of the present invention.

In addition, in the case of the pressing head 130, as in the case of the cylindrical shape as described above, it is possible not to form a protrusion like the conventional one on the outer side, and to prevent the conventional recess in the pipe P from being formed.

The pressure head 130 as described above is connected to the gripper 140 disposed on the bottom surface of the pressing head 130 so that the user or the automation device can more easily move the pressing head 130 through the gripper 140 Do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
