Abstract

PURPOSE:To enable to simply and surely fix a mounting body to a body to be mounted by a method wherein a metallic rotating bar is pressed against the tip side of a protruded part so as to deform the tip of the protruded part by means of the frictional heat due to the rotation of the bar in such a manner as to bridge a boss hole over its edge and at the same time to press some portion of the tip in the bore of the boss hole. CONSTITUTION:The protruded part b1 of a face part B is assembled by being inserted in an oblong hole a1 in such a manner as to stick the tip out of the back surface side of a finisher A. A metallic rotating bar T is pushed against the tip held in a vertical line directing upward. A round bar with a hemi-spherically hollowed out dent t1, the surface of which is applied with smoothing treatment such as chrome plating or the like, on its tip surface is employed as the rotating bar T. By pressingly lowering the rotating bar T while being rotated at constant speed, the face part B is tightly fixed to the finisher part A through the engagement of a flange part b2 with the edge of the boss hole a1 and the embedment of the bore of the boss hole a1 with the deformed part b3. In addition, because no deformed part b3 is exposed to the front surface side, no surface properties of the finisher A is impaired.

(See Figures 3 a and b), insert the protrusion bl protruding from the back of the face part B into the boss hole a1 formed on the plate surface of the finisher A.
(see Figures a, b, c), press a pre-heated press rod P against the tip of the boss and gradually melt the protrusion from the tip, thereby forming a bridging portion b2 on the edge of the boss hole a. Te (4th

Tame bridging part b
Insufficient molding in step 2 causes wobbling in the mounting state of face part B, and if the heating temperature is too high, the protrusions melt excessively, resulting in insufficient mounting strength, and furthermore, the press rod stops rotating without rotating. Because of this, there are problems such as molten resin adhering to the tip and preventing tight heat conduction.

It is difficult to apply this method to face parts and the like.

付体を固定するようにされている。Means for Solving the Problems In the method for fixing the mounting body according to the present invention, a rotating metal rod is pressed against the tip of the protrusion, and the frictional heat generated by the rotation causes the tip of the protrusion to move around the edge of the boss hole. The mounting body is fixed by being deformed so as to bridge the boss hole and also press-fitting a portion into the diameter of the boss hole.

。In this embodiment, similarly to the case shown in FIG. 3, a vehicle finisher A is used as an object to be attached, and a face part B is fixed as an attachment object to the surface side of the vehicle finisher A. The finisher A is formed into a plate shape from ABS resin or the like, and a plurality of horizontally elongated holes a1 serving as boss holes are provided on the plate surface. Note that it is desirable to locally form a thick part a2 around the horizontally elongated hole a1, which is thicker than other parts. On the side is the oblong hole a of finisher A! A plurality of protrusions are integrally molded to be inserted into the protrusion. The oblong hole a1 is
- Assemble part B to finisher A (=to make it easier to insert, the outer shape of the protrusion b1 is slightly larger than that of the protrusion part B1, and when the protrusion part A is inserted into the horizontally long hole a, the desired length is the same as that of the finisher A. It is formed to be elongated so as to protrude from the back side.

With it facing upward, press the metal rotating rod T against the tip. This rotary rod T has a hemispherical depression 1. It is best to use a rod with a smooth surface treated with chrome plating or the like, and when the rotating rod T is rotated at a constant speed and pressed down, the protrusion will soften from the tip side due to the frictional heat caused by the rotation. It gradually deforms and deforms into a hemispherical shape so as to bridge the edge of the boss hole a1. When this suppressed descent of the rotating rod T is continued until the tip of the rod slightly bites into the thick part a2 on the rear surface of the shaft A, the resin constituting the finisher A is also heated and softened. The protrusion is
The protruding end side is formed into a flange portion b2 that closely bridges the edge of the boss hole a1.

is securely fixed to the finisher A by the engagement of the flange portion b2 with the edge of the boss hole a and the deformed portion b3 that fills the inside diameter of the boss hole al, and since the deformed portion b3 is not exposed on the surface side, the surface of the finisher A is No loss of sex.

It can be widely applied to anything. In addition, the protrusion bl is provided with a stepped portion b4, and the boss hole a1 is
