Abstract

PURPOSE:To prevent the occurrence of cracking by plastically flowing a metal, and coupling a diaphragm and its attachment parts with a connecting shaft. CONSTITUTION:The negative pressure reacting device consists of the 1st negative pressure chamber 1a composed of cases 2a and 3a and a diaphragm 4a, the 2nd negative pressure chamber case 1b composed of cases 2b and 3b and a diaphragm 4b, compression springs 5a and 5b, connecting shafts 6a and 6b, and pistons 9a and 9b. The connecting shafts 6a and 6b are provided with W-shaped grooves and while diaphragms 4a and 4b are compressed by applying pressure to a washer 11 and a joint 7, metals of the washer 11 and joint 7 bite into the grooves 6a and 6b, thereby coupling the diaphragms.

Description

As described in the 2010 publication, it is common to swage the shaft that fits into the diamond 7 and F, and for productivity, this shaft is either cut from free-cutting steel or is cold-forged. However, free-cutting steel has relatively little elongation, and cold-forged products are hard due to work hardening and cracks occur during tightening, causing problems with airtightness. Furthermore, when heat treating the shaft, partial hardening is required, which reduces productivity.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、前述のかしめによるクラックまたは熱
処理の有無に関係のない品質、生産性の高い結合法を提
供するにある。An object of the present invention is to provide a bonding method with high quality and productivity regardless of cracks caused by caulking or the presence or absence of heat treatment.

〔発明の概要〕[Summary of the invention]

本発明は、金属の塑性流動を応用し、弾性体を圧縮する
と同時に、該金属を軸に結合させるものである。The present invention utilizes the plastic flow of metal to compress an elastic body and simultaneously connect the metal to a shaft.

5b is a compression spring, 6a.

６ｂは連結軸でおる。７はＵ字状の継手、８はストッパ

１０ｂは当板である。１１は比較的歌い金属のワッシャ
、１２ａ、１２ｂは口金を示す。以上は公知の構造でる
る。10b is a contact plate. Reference numeral 11 indicates a relatively smooth metal washer, and 12a and 12b indicate caps. The above is a known structure.

ａ、６ｂに喰込ませて結合する。Reference numerals 13a and 13b are W-shaped grooves provided in the connecting shafts 5a and 5b, and at the same time, the washer 11 and the joint 7 are pressurized and the diaphragms (generally containing base fabric) 4a and 4b are compressed using the method shown in FIG. The washer 11 and the metal of the joint 7 are connected to the groove 6.
Insert into a and 6b and join.

一である。Next, another embodiment will be explained with reference to FIG. For example, if the diaphragm 4a is made of rubber and does not contain any base fabric, it is sufficient to provide the connecting shaft 6a with a step 15 for defining the compression margin of the diaphragm 4a, and the effect is the same as described above. .

〔発明の効果〕〔Effect of the invention〕

本発明によれば、比較的歌い金属を、局部的に塑性流動
