る。That is, as shown in FIG. 5, the rotary welding member A, taking a stud as an example, has a disc-shaped flange part A2 at one end of the column part A1, and a disc-shaped flange part A2 on the opposite side of the welded part of the flange part A2. This includes integrally molded holes made of synthetic resin, with engaging protrusions A3 facing each other and protruding from the peripheral edge. As shown in FIG. 6, the engaging protrusion A3 of the rotary welding member A is engaged with the engaging groove 2a of the engaging member 2 at the tip of the rotary welding I/s1, and Press the flange portion A2 of the rotary welding member A with the tip surface of the abutting member 3 to attach the synthetic resin mounting surface B.

It is rotatably accommodated in the inside, is engaged with a drive shaft 5 of a rotary drive device (not shown), rotates integrally with the drive shaft 5, and is urged toward the distal end side by a coil spring 6. has been done.

When the drive shaft 5 is rotated at high speed by pressing the back side of the flange part A2 of the rotary welding member A against the mounting surface B and compressing the coil spring 6, the flange part A2 Frictional heat is generated between the back surface and the mounting surface B, and the contact surfaces melt and adhere to each other due to the heat. Therefore, the molten part is then cooled and hardened, and the rotary welding member A is fixed across the mounting surface.

次の問題があった。Problems to be Solved by the Present Invention> However, in the conventional rotary welding WIN in which the rotary welding member A is pressed by the built-in coil spring 6,
I had the following problem.
（イ）回転溶着の際に、回転溶着部材Ａ及び取付面Ｂの

溶着部材Ａのフランジ部Ａ２が取付面Ｂに強固に取付け

となることがあった。(a) During rotary welding, the rotary welding member A and the mounting surface B melt and the rotary welding member A gradually moves toward the mounting surface B. As a result, the axial length of the coil spring 6 increases, so that the coil spring The pressing force caused by 6 gradually becomes weaker. For this reason, the pressing force at the end of rotary melting is gradually weaker than it was at the beginning, so it is not pressed sufficiently against the mounting surface B, and the flange portion A2 of the rotary welding member A is not firmly attached to the mounting surface B. The flange portion A2 to the rotary welding member was sometimes in a floating state.

交換が面倒なため、押圧力の異なる回転溶着機を多数用
意しなければならなかった。(b) The pressing force must be adjusted depending on the hardness of the rotary welding member A and the mounting surface B, but since the coil spring 6 is used, many types of coil springs with different degrees of elasticity are prepared and the main body is disassembled each time. The coil spring had to be replaced, which was very troublesome. Alternatively, since it is troublesome to replace the coil spring, it is necessary to prepare a large number of rotary welding machines with different pressing forces.

。Effects of the Invention> As described above, in the rotary welding machine of the present invention, (a) the engaging member 30 and the corresponding parts are melted by melting the back surface of the flange portion A2 of the rotary welding member A and the mounting surface B during rotary welding. Even if the contact member 33 moves toward the mounting surface B, it is pressed by air pressure, so the pressing force can always be kept constant.
It is possible to eliminate the above-mentioned conventional problems such as incomplete welding due to changes in the pressing force during rotational welding.

Since it is necessary to adjust the pressing force on the rotary welding member A, conventionally, many types of coil springs with different elastic dusts are prepared, and the main body is disassembled each time and the coil springs are replaced. It was necessary to prepare many types of rotary welding machines, but with the present invention, only a C-pu is required to change the air pressure, which greatly simplifies the rotary welding work.
