法等が用いられている。 As an example of the caulking method for resin parts, for example, as shown in FIG. A method of inserting into the prepared hole 3 and forcibly press-fitting the pin 9' into the rivet to swage the tip of the shaft into a chrysanthemum shape, or inserting the semi-tubular rivet 6 into the prepared hole 3 as shown in Fig. 2 and tightening it. A method of caulking with a mold 8, or a method of filling a washer 4, inserting a solid rivet 7 into the prepared hole 3 and caulking with a fastener 9, etc., as shown in FIG. 3, are used.

プの要因ともなる。 In each of the above methods, it is necessary to drill pilot holes 3 in the resin parts 1 and 2 in advance. There are methods for perforating the resin part during molding or after molding, but in either case the mold is expensive, and in the latter case it is a separate process and a cutting mold is required. Also, general-purpose resins have difficulty achieving dimensional accuracy, so if there are many rivet crimping locations, the positions of the holes will be misaligned. Therefore, it is necessary to make the pilot hole larger, but since resin is weaker than metal, in order to obtain the desired peel strength, the rivet head must be made larger as the diameter of the pilot hole increases. Furthermore, the fastening area must be expanded by inserting a washer. Furthermore, in addition to the increased man-hours for inserting washers and aligning holes, large quantities of washers are consumed due to mass production, which is a factor in increasing costs.

かしめ付け法を提供するものである。 As mentioned above, the present invention relates to a method of caulking a resin part while drilling a pilot hole for a rivet, and is intended to solve the problems of the various caulking methods described above, and also to eliminate the scraps generated when forming the pilot hole. A rivet in a resin part in which a part or all of the rivet is compressed and pushed into the rivet shaft hole to increase the capture force in the hole, thereby ensuring that the rivet remains in the hole and effectively affecting the caulking strength. This provides a caulking method.

The shaft hole 12b has a shaft 12a extending downward by 2d, and a shaft hole 12b with a bottom that opens at the end surface of the shaft 12a. The shaft hole 12
b is a resin part 10 that is self-perforated at the end of caulking;
It extends to the axial center of the shaft 12a with a length reaching into the prepared hole 11, and forms a shaft cylindrical portion 12c.

しめ付けを終結する。 As shown in the figure, the resin parts 10 and 11 are supported on a jig 13, and the rivet 12 is driven into the resin parts 10 and 11 that do not have pilot holes, and the scraps 10a and 11 generated by driving the rivet are removed. 11
A is press-fitted into the shaft hole 12b from the opening in the end face of the shaft portion. That is, as the rivet shaft 12a is driven into the resin parts 10 to 11, scraps 10a and 11a are generated according to the driving depth, and the scraps 10a and 11a are pressed into the shaft hole 12b by the driving pressure. It comes to be done. The tip of the rivet shaft 12a, that is,
As the tip of the shaft cylindrical portion 12c passes through the resin parts 10 and 11, the pilot hole 14 is completely drilled, and the shaft hole 12
A part of the shaft cylindrical portion 12c forming the opening hole wall of b is a jig 13 that supports the resin parts 10 and 11.
When the rivet head 12d is forcibly expanded outward at , the rivet head 12d comes into close contact with the upper surface of the resin part 10, and the shaft hole 12b
The caulking is completed at a position where a portion of the screw extends sufficiently into the pilot hole 14.

確保又は強化する。 At the same time, scraps 10a and 11 are separated from the resin parts 10 and 11 as the pilot hole 14 is completely drilled.
a is compressed and pushed into the bottom of the shaft hole 12b extending into the pilot hole 14 using the jig 13 to complete the caulking. The scraps filled in the shaft hole 12b in a compressed state generate an external pressure P 2 as a reaction.
This produces an internal pressure P 1 that opposes the . As a result, the shaft cylinder portion 12
c Increase the degree of adhesion of the hole wall to the inner wall surface of the prepared hole to ensure or strengthen the fastening force.
本発明によれば軸孔１２ｂを抜きくずの逃がし

ずの残留によりかしめ付け強度、即ち引剥し強度
の確保が図られる。 According to the present invention, by using the shaft hole 12b as an escape hole for the cutting chips, self-drilling of the pilot hole can be performed appropriately, and at the same time, the caulking strength, that is, the peeling strength can be increased by the residual drilling of the pilot hole in the shaft hole 12b. Strength is ensured.
上記作用効果は第９図に示すように、下穴１４
内に延在される軸孔１２ｂの容積を抜きくず１０
ａ，１１ａの体積以下に設定し、その差を適度に
選択することによつて得られる。 As shown in FIG.
The volume of the shaft hole 12b extending inside is removed and the waste 10
This can be obtained by setting the volume to be less than or equal to the volume of a and 11a, and selecting an appropriate difference between them.
上記容積と体積の関係は下穴１４内に延在させ

肉厚Ｈの関係（ｈ＜Ｈ）に置き換えられる。 The relationship between the volumes described above is replaced by the relationship between the depth h of the shaft hole 12b extending into the prepared hole 14 and the wall thickness H of the resin parts 10 and 11 (h<H).
この場合、軸筒部１２ｃは軸筒部先端より基部

0a is press-fitted into the bottom of the shaft cylinder, which has higher rigidity, and remains in the shaft hole 12b more reliably due to the strong catching force received from the shaft hole wall.

しめ付け強度の確保等の上記効果を遺憾無く発揮
させることが可能となる。 According to the present invention, it is possible to perform caulking while self-drilling the pilot hole 14 as described above, and
a, 11a can be effectively used to secure the riveting strength, and the scraps 10a, 11a that are press-fitted into the shaft hole can be used to form a hole wall, that is, the shaft cylinder part 1.
2c, effectively prevents the tip from slightly displacing inwardly, and effectively prevents it from buckling during caulking. In addition, the volume of the shaft hole 12b extending into the prepared hole is set to be less than the volume of the chips 10a, 11a, so that the large volume of chips 10a, 11a generated during rivet driving is compressed into the small volume shaft hole. By pushing the rivet while pushing it in, a stronger catching force can be generated in the shaft hole, and the above-mentioned scraps 10a and 11a remain accurately in the shaft hole, and this residual ensures the rivet caulking strength. It becomes possible to bring out the above effects to the fullest.

強度を著しく高める。 Since caulking is performed by self-drilling, the step of drilling pilot holes into the resin parts can be omitted, and the fastening force for the resin parts 10, 11 is reduced compared to methods such as drilling pilot holes in advance and caulking with rivets. will improve dramatically. That is, the peel strength of the resin parts 10, 11 is significantly increased.

付け強度を増強する効果がある。 Further, according to the present invention, the scraps from the upper resin part into which the rivet is driven and the lower scraps from the lower resin part are forcibly expanded from the opening wall (tip of the shaft cylinder) of the rivet shaft hole due to the above compression. This has the effect of preventing the distal end of the shaft cylinder from buckling due to the expanding action of the two punched scraps, promoting the aforementioned expansion, and increasing the clamping strength.

おけるリベツトかしめ付け法。1. Drive a rivet with a shaft hole into two resin parts that do not have pilot holes and are to be caulked, and while pressing the scraps generated during driving of the rivet into the shaft hole from the opening at the end of the rivet shaft. A pilot hole is self-drilled by penetrating the resin part, and the opening wall of the shaft hole protruding from the resin part is compressed and deformed in the shaft hole using a jig that supports the resin part. By forcibly expanding outward and caulking, the compressive deformation force of the scraps of both resin parts in the shaft hole acts as a forced expansion force from the hole wall of the opening of the shaft hole, and the above-mentioned bottom The volume of the shaft hole extending into the hole is set to be less than the volume of the scraps, and by this setting, the scraps of both resin parts generated during rivet driving are pushed to the bottom of the shaft hole by the rivet driving pressure. A rivet caulking method for resin parts, characterized by compressing and pushing the rivets into the shaft hole so that the rivets remain in the shaft hole.
