[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a nozzle for applying a sealing material for sealing a gap between plate assemblies when assembling an automobile body, for example.

[0002]

2. Description of the Related Art Conventionally, when assembling an automobile body, a sealing material is applied to gaps between constituent members for waterproofing, dustproofing and the like. In order to uniformly and reliably seal the gap such as the joining surface of the panel, the application of the sealing material is usually performed along the joining portion while discharging the sealing material from the tip of the sealing nozzle, and moving along the joining portion. It is applied in such a manner as to bead up around it.

[0003]

However, in the case of the conventional sealing nozzle, for example, as shown in FIG. 4, the joint portion P of the panel is in the vicinity of the opening / closing hinge portion H of the trunk lid T and the like. In the case where the sealing material S is applied in a case where the nozzle cannot be inserted because it is obstructed by the edge of the trunk lid T, the trunk lid T is opened to a predetermined angle or more, for example, as shown in FIG. Needed. If the nozzle 50 cannot be inserted even when the trunk lid T is opened in this way, measures such as changing the design of the opening / closing mechanism or changing the position of the hinge H so that the nozzle 50 can be inserted are taken. Was needed.
Therefore, there has been a demand for the development of a sealing nozzle that can easily and reliably apply a sealing material without opening the trunk lid T or the like or changing the opening / closing mechanism.

[0004]

In order to solve this problem, the present invention provides a bent portion by bending the tip of the nozzle,
The bent portion was provided with a horizontally elongated discharge port whose opening width was widened toward the tip end side of the nozzle. Further, a nozzle guide member was provided in a direction opposite to the bending direction of the bent portion.

[0005]

[Function] By providing a bent portion at the tip of the nozzle, it is possible to insert and apply from the side, for example, around the opening / closing hinge of the trunk lid, which could not be applied with the conventional sealing nozzle. Becomes Also, if the sealing material is applied while being discharged from the horizontally long discharge port provided in the bent portion, it is possible to apply the sealing material with a bead width corresponding to the length of the discharge port. Since the width is widened, the coating amount in the bead width direction can be made uniform. That is, since the opening width on the tip side of the nozzle with a low discharge pressure is widened and the opening width on the base end side with a high discharge pressure is narrow, the discharge amount can be balanced along the length direction of the discharge port.
Further, if the nozzle guide member is brought into contact with a member or the like around the application section, the application can be performed even when the application section cannot be visually recognized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the sealing nozzle of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view of the sealing nozzle of the present invention, FIG. 2 is a front view, and FIG. 3 is an operation view.

[0007] The sealing material is sealed with a sealing nozzle or the like at the joint of the vehicle body steel plate at the stage of completion of the assembly in order to seal the gap at the joint of the vehicle body panel for waterproofing, dustproofing, soundproofing, vibrationproofing, etc. Served.

[0008] The sealing nozzle of the present invention is configured so that it can be easily applied to the joint of the roof around the opening / closing hinge portion of the trunk lid, which is difficult to apply with the conventional nozzle. .

That is, as shown in FIGS. 1 and 2, the sealing nozzle 1 of the present invention is formed by bending the tip of a circular tubular nozzle portion 2 at a substantially right angle to form a bent portion 3. The cross-sectional shape is formed in a rectangular shape.

The bent portion 3 is provided with a horizontally elongated discharge port 4 along the direction in which the nozzle extends, and its length t is determined according to the width of the sealing material.

Further, as shown in FIG.
It is formed in a substantially triangular shape such that the opening width n on the nozzle tip side B is wider than the opening width m on the base end side A of the nozzle, and the base of the triangle is close to the bottom surface of the bent portion 3 It is provided.

On the other hand, a nozzle guide member 5 is provided on the opposite side of the bent portion 3 from the bending direction.

The nozzle guide member 5 is formed, for example, by bending a steel rod into a curved shape and fixing it to the side surface of the nozzle portion 2 by welding or the like.

Incidentally, the specifications of the sealing nozzle 1 are as follows: the outer diameter of the tubular nozzle portion 2 is about 4 mm, the bent length of the bent portion 3 is about 27 mm, and the length t of the discharge port 4 is 18 mm.
The opening width A of the discharge port 4 on the nozzle base end side is about 0.5 mm, the opening width B of the discharge port 4 on the nozzle tip side is about 1.5 mm, and the diameter of the nozzle guide member 5 is 2 mm. It is about.

The operation of the above sealing nozzle 1 will be described.

As shown in FIG. 3, around the body BODY side of the trunk lid T where the hinge portion H is provided,
For example, the junction P with the roof ROOF is formed to be long in the direction perpendicular to the paper surface, and the edge of the trunk lid T faces above the junction P in a state where the trunk lid T is kept closed, so that it can be directly viewed. Can not.

Accordingly, the sealing nozzle 1 is inserted from the side of the edge of the trunk lid T, and is applied while the projecting end of the nozzle guide member 5 is in contact with the rising portion of the roof ROOF.

That is, the overhang width h of the nozzle guide member 5 is set so that the discharge port 4 faces the position of the joint P with the overhang end abutting on the rising portion of the roof ROOF. Therefore, if the projecting end of the nozzle guide member 5 is brought into contact with the roof ROOF and is fed in the direction perpendicular to the paper surface, the coating can be performed even if the joint P is not visible.

The sealing material S discharged from the discharge port 4 has a large opening width n on the nozzle tip side and a narrow opening width m on the nozzle base end side with a low discharge pressure. Are discharged uniformly along the line.

At this time, since the bottom of the discharge port 4 is close to the bottom of the bent portion 3, the sealing material S is stably applied to the upper surface of the joint P.

Needless to say, the sealing nozzle 1 is not limited to the application around the opening / closing hinge portion of the trunk lid T.

[0022]

[Effect of the Invention] As described above, the sealing nozzle of the present invention has a bent portion at the tip, so that it can be directly applied to a joint portion of a steel plate which cannot be applied by the conventional nozzle. It becomes possible, and for example, it is not necessary to open the trunk lid or the like and work. In addition, by providing a horizontally long discharge port at the bent portion and making the opening width of the discharge port wider at the nozzle tip side, the discharge amount becomes uniform and the quality is improved. In addition, by providing the nozzle guide member, it is possible to apply even at a portion where the joint portion is not visible.
