る。The conventional scroll surface preparation method is the fm processing method, which is a combination of Hirota casting and NC machining, but after the previous inspection, there was a limit to the precision of the DIJ machining of large lap bottoms, which became NC machining/de-mill machining. The i0 model, which is suitable for mass production, is not suitable for mass production, as it takes a long time to manufacture, and two plastic-processed tabs are inserted into the grooves formed on the head plate by plastic/Jll machining, so it is necessary to saw the head plate and wrap. There is a possibility of practical application.

ップを別々に製作する方法が最も有効である。An object of the present invention is to provide a method for manufacturing a scroll for a scroll compressor that can maintain high assembly precision between an end plate and a wrap. In order to maintain the scroll pressure (mho), it is mainly necessary to make the axial gap 5 μm or more, but the most effective method is to separately manufacture the Kfi end plate and the wrap for this gap.

る。′。Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. The wrap 5 is manufactured by powder metallurgy, injection molding, machining, plastic working, casting, etc. After manufacturing, two holes are formed on the end surface. On the other hand, a pin hole 41r is provided in the end face of the um-plate in the same way as the one set of lamps 1. Note that the pin holes 2 and 4 may be penetrating ones. After that, from the bottle 6t-wrap side, 4fi
The wrap L and end plate 3 are integrated by loading from the direction that is easy to assemble, even from the L plate side. In this case, the bottle 50 charging method may be cold fit, shrink fit, screw fastening, or press fit. When particularly high performance and high reliability are required for the compressor, a Teflon plate 6 is generally installed between the lug 1 and the plate 3 to improve sealing and conformability, as shown in Fig. 2. It's okay to go. This Teflon plate 6 may be provided on a part of the surface where a sealing effect and a conforming effect are expected, or may be provided on the entire surface. The material of the lamp 1 may be glass, HT alloy, ceramic steel, cast iron, or steel, and the same applies to the plastic 15 and the plate 4. FIG. 3 is a cross section of the scroll after assembly. '.
上記Ｏように組立てることにより軸方向Ｏシール効果が
看しく向上する友め、体積効率が３％向上する。By assembling as described above, the axial O-seal effect is noticeably improved, and the volumetric efficiency is improved by 3%.

るため、安定して１１ｉＩＩい性能が維持できる。In addition, since the number of processing steps and assembly errors are reduced, productivity is significantly improved. As a specific example, the machining fraction is 1/1 of the current Ichizoku NC machining! OK, it can be shortened. The assembly lig difference will be increased by improving the processing accuracy of the bottle to 15 pm or less. Moreover, since the flatness of the lug and end plate, which most affect the performance of the eighth scroll compressor, has a flatness of 2 to 3 μm, it is possible to stably maintain the performance of 11iIII.
以上説明したように、本発明によればスクロールの生産

幾細される。As explained above, according to the present invention, the productivity of scrolls is significantly reduced compared to the conventional method of casting and forming by NC processing.
