200523477 ⑴ 九、發明說明 [發明所屬之技術領域】 本發明是有關於渦卷式壓縮機的組裝方法’進一步詳 細說明的話，是將支撐冷媒的壓縮部的主框架裝設於密閉 容器的容器胴體內時，改正容器胴體的製造上的變形’一 邊正確地進行對位一邊將壓縮部裝設於容器胴體內的渦卷 式壓縮機的組裝方法。 【先前技術】 渦卷式壓縮機，已知有利用使由固定渦卷及繞轉渦卷 組成的2個渦捲取狀的渦卷搭接板相互嚙合並在硏磨間形 成月牙狀的壓縮空間，藉由將繞轉渦卷對於固定渦卷公轉 繞轉運動，使壓縮空間的容積隨著從硏磨的外側朝向中心 漸漸減少來壓縮冷媒的原理的壓縮機。 渦卷式壓縮機的內部構造的一例如第9圖所示，對於 此說明。此渦卷式壓縮機1，是在縱置設置的圓筒狀的密 0 閉容器2的內部配置有主框架3，在主框架3的上側設置 壓縮部4，該壓縮部4具有固定渦卷4 1及繞轉渦卷42， 藉由軸6驅動壓縮部4的電動機5是設置在主框架3的下 側。 在主框架3設有供軸支軸6的主軸6 1的一端側用的 主軸承31，在密閉容器2內進一步設有具有供軸支軸6 的主軸6 1的他端側用的副軸承7 1的副框架7。 在主框架3及副框架7之間設有電動機5，電動機5 -4 - (2) (2)200523477 是具有：固定於容器胴體21的內周面的固定子51、及同 軸地配置於固定子5 1內側的轉子52，轉子52是一體地 安裝於軸6。 主框架3及副框架7是熔接固定於容器胴體2 1 ’當 熔接兩者時，需要在主軸承3 1及副軸承7 1的軸線一致地 相互對位的狀態下進行固定。 即，主軸承3 1及副軸承7 1的軸心的偏離大的話’因 在各軸承部3 1、7 1所發生的單點接觸電動機5的負荷會 φ 增大。且，固定子5 1及轉子5 2之間的磁性間隔的平衡會 崩潰可能會使壓縮機的起動性悪化。 在此，在專利文獻1 (日本專利3 2 5 0 3 4 8號公報）中， 揭示了配合主框架3及副框架7的軸心將容器胴體2 1精 度佳地熔接固定的方法的一例。此專利文獻1的組裝方 法，首先第1過程如第10圖（a)，將主框架3載置於固定 基台8的水平基準面81上，藉由挾盤爪82對位固定後， 藉由昇降手段將事先安裝好固定子51的容器胴體21朝向 鲁 主框架3下降，進一步藉由固定手段（皆無圖示）固定主軸 承3 1及固定子5 1，將容器胴體2 1的下端側熔接於主框 架3。 接著，第2過程如第1 〇圖（b)，使一體地安裝於轉子 5 2的軸6通過容器胴體2 1的內部安裝於主框架3的主軸 承31。而且，第3過程作如第1〇圖（c)，將藉由對位裝置 9保持的副框架7從容器胴體2 1的上端插入，進行副框 架7的對位並將容器胴體2 1的上端側熔接於副框架7。 -5- 200523477 (3) 之後，在別的過程進行對於主框架3的壓縮部4的安裝。 通常，使用於壓縮機的容器胴體2 1因爲是將厚的鋼 板加工成圓筒狀所以具有加工時的變形’在幾乎大多數的 情況不是正確的正圓。且，即使無接縫的圓筒體也無法保 證是正圓。且，因由熔接所產生的凝固時間差可能使容器 胴體2 1更歪斜。進一步因主框架3及副框架7的熔接可 能使容器胴體2 1更歪斜。 且，將壓縮部4安裝於主框架3的情況時，主框架3 φ 之外也需要進行固定渦卷4 1及繞轉渦卷42的相對的位置 對合（調芯），但是進行該調芯作業的情況時，在上述專利 文獻1中，在主框架3中因爲先安裝好容器胴體21，所 以無法直接抓住主框架3，因爲是以容器胴體2 1的外周 爲基準進行調芯作業所以精度上不太較佳。 且有別的問題，如上述專利文獻1的軸6，因爲是使 形成於其先端的曲柄軸6 2存在於主軸6 1的旋轉半徑內， 所以即使將主框架3載置於固定基台8上，也可將軸6插 φ 通主框架3的主軸承3 1。但是，此軸因爲會獲得壓縮能 所以需要加粗主軸6 1的徑，加粗徑的話，主軸承3 1的滑 動損失不只是變大，轉子5 2的容積會減少，電動機5的 動力也會下降。 在此，雖因使用曲柄軸6 2比主軸6 1的旋轉半徑更伸 出外側地形成的軸而性能上較佳，但是使用此軸的情況 時’將壓縮部4組裝在主框架3之前，因爲需要事先將別 的形態的軸插通主框架3的主軸承3 1，所以無法適用上 -6- 200523477 (4) 述專利文獻1的組裝方法。 [發明內容】 本發明是爲了解決上述問題，其目的，是將支撐冷媒 的壓縮部的主框架裝設於密閉容器的容器胴體內時，改正 容器胴體的製造上的變形，一邊正確地對位一邊將壓縮部 裝設於容器胴體內。且，本發明的其他的目的，是可將事 先組裝了壓縮部及主框架的壓縮元件組裝於密閉容器。 爲了達成上述目的，本發明，是一種渦卷式壓縮機的 組裝方法，是在密閉容器內，具備··具有固定渦卷及繞轉 渦卷的壓縮部、及通過軸驅動上述繞轉渦卷的電動機、及 具有可軸支上述軸的主軸的一端側的主軸承並支撐上述壓 縮部的主框架、及具有供軸支上述軸的主軸的他端側的副 軸承用的副框架，其特徵爲，先實施前組裝過程，其是包 含：組裝上述壓縮部及上述軸壓縮元件於上述主框架並形 成壓縮元件的組裝過程、及將上述電動機的轉子一體地安 馨 裝於上述軸的主軸的轉子安裝過程；再實施後組裝過程， 其是包含：上述軸成爲垂直的方式使上述壓縮元件成爲水 平狀態地組裝於壓縮元件固定台上的壓縮元件水平校正過 程、及藉由壓縮元件固定手段在上述壓縮元件固定台上使 上述軸的軸線位置於該壓縮機的中心線上的方式定位固定 上述壓縮元件的壓縮元件對位過程、及藉由容器保持手段 支撐上述容器胴體使與上述軸的軸線同軸，藉由第1壓入 手段使上述壓縮元件固定台及上述容器保持手段相對地移 200523477 (5) 動直到上述容器胴體的一端側的開口部抵接於上述壓縮元 件固定台爲止，將上述壓縮元件壓入至上述容器胴體的一 端側的開口部內的壓縮元件壓入過程、及藉由上述第1壓 入手段將上述容器胴體按壓於上述壓縮元件固定台的狀態 下’藉由熔接手段將上述容器胴體一體地熔接於上述壓縮 元件的壓縮元件熔接過程。 在上述壓縮元件水平校正過程中，藉由正確進行水平 校’使水平基準面是形成於上述固定渦卷的裏面側較佳。 φ 且’在本發明中也含有副框架的安裝有過程。即，在 上述後組裝過程中進一步包含：使上述副框架成爲水平狀 態地組裝於副框架固定台的副框架水平校正過程；及藉由 副框架固定手段在上述副框架固定台上使上述副框架的軸 線位置在該壓縮機的中心線上的方式定位固定上述副框架 的副框架對位過程；及藉由第2壓入手段相對地移動上述 副框架固定台及上述容器保持手段直到上述容器胴體的他 端側的開口部抵接於上述副框架固定台爲止，將上述副框 φ 架壓入上述容器胴體的他端側的開口部內的副框架壓入過 程；及藉由上述第2壓入手段將上述容器胴體按壓於上述 副框架固定台的狀態下，藉由熔接手段將上述容器胴體一 體地熔接於上述副框架的副框架熔接過程。 對於上述副框架水平校正過程，也藉由正確進行水平 校正’使水平基準面形成於上述副框架的裏面側較佳。 且’在上述副框架固定台具備電磁鐵的態樣也含在本發 明。 -8- (6) (6)200523477 依據本發明的較佳態樣’正確地進行上述壓縮元件的 對位之外’上述壓縮元件固定手段具備複數挾盤爪，該複 數挾盤爪是等間隔配置在以該壓縮機的中心線爲中心的圓 周上，且，沿著其圓的半徑方向移動可能，與形成於上述 固定渦卷側的挾盤溝卡合。 且，上述各挾盤爪可朝垂直方向昇降，該下降動作時 藉由上述挾盤溝將上述壓縮元件朝上述壓縮元件固定台側 按壓較佳，但是別的態樣，如上述挾盤溝是在與上述挾盤 φ 爪卡合的部分具有將水平力變換成向下力的錐面，上述挾 盤爪朝上述半徑方向內側移動時，藉由上述錐面將上述壓 縮元件按壓於上述壓縮元件固定台側也可以。 在本發明，上述主框架及/或是上述副框架，是在外 周面具有在與上述容器胴體的內面之間形成預定寬的間隙 的凹部，上述凹部是被選擇作爲上述熔接手段的熔接處較 佳。依據此，可使由熔接所產生的熔接變形退避至凹部。 上述凹部是形成沿著上述外周面的圓周方向的一連的 φ 環狀溝也可以，別的態樣，如上述凹部是沿著上述外周面 的圓周方向部分地形成也可以。 依據本發明，上述軸是具有：作爲上述電動機的輸出 軸的主軸、及對於上述主軸偏心形成且與上述繞轉渦卷連 結的曲柄軸，上述曲柄軸是形成比上述主軸的外控更伸出 外側的情況時，在上述壓縮元件組裝過程中，將上述軸的 主軸插通於上述主框架的主軸承，將上述曲柄軸連結於上 述繞轉渦卷後，將上述固定渦卷安裝於上述主框架。 -9- (7) (7)200523477 依據本發明，藉由將容器胴體壓入主框架，即使於容 器胴體具有製造上的變形，也可使容器胴體貼附於主框架 的外周面地緊密嵌合。副框架側也同樣，因此可一邊正確 地進行對位一邊將壓縮部裝設於容器胴體內。 且，因爲可將事先組裝了壓縮部、主框架及電動機的 軸壓縮元件組入密閉容器內，所以具有曲柄軸是突出主軸 的外徑的外側的軸的渦卷式壓縮機也適用。 【實施方式】 接著，一邊參照圖面，一邊說明本發明的實施例。首 先’第1圖的剖面圖是顯示依據本發明組裝的渦卷式壓縮 機的內部構造，雖對此進行說明，但是本發明不限定於 此。然而，與上述習知例同一或是被認爲同一處是使用相 同參照符號。 如第1圖所示，此渦卷式壓縮機1 0是具有縱置的圓 筒狀的密閉容器2，在其內部收納有··主框架3、冷媒的 0 壓縮部4、電動機5、軸（旋轉驅動軸）6及副框架7。然 而，在密閉容器2內中，另外收納有：驅動電動機5用的 電源纜線、潤滑用的潤滑油等，但是這些對於本發明因非 重要的構成要素，所以未特別圖式，且其說明也省略。 密閉容器2是具備：圓筒狀的容器胴體2 1、及一體 地安裝於同容器胴體2 1的兩端側的上蓋2 2及下蓋2 3。 容器胴體2 1是將厚的鋼板加工成圓筒狀並熔接兩端的圓 筒體或是無接縫的圓筒體的任一也可以。上蓋22及下蓋 *10- (8) (8)200523477 2 3，是在最終過程熔接於容器胴體2 1。 主框架3，是具有外周幾乎形成正圓狀的圓盤狀的框 架，在其中央形成軸支軸6的主軸61的主軸承31。在主 框架3的上面側形成收納凹部3 2，藉由自轉防止用的歐 丹環3 3收納繞轉渦卷4 2的鏡板4 2 1。主框架3因爲被壓 入容器胴體2 1內，所以其外徑是形成比容器胴體2 1的內 徑若干大。 收納凹部3 2的中央是形成更低一段，軸6的曲柄軸 鲁 6 2、及繞轉渦卷4 2的轂部4 2 3是在繞轉運動可能的狀態 下被容納。且，在主框架3中，設有藉由形成於軸6內的 導油孔6 3將供給至主框架3上部的潤滑油返回至密閉容 器2的底部側用的無圖示排油通路。且，內部高壓型的情 況時，在主框架3中設有將在壓縮部4的密閉作動室生成 的高壓冷媒導引至電動機室用的無圖示的冷媒通路。 主框架3，是藉由例如切削加工形成，其外周面雖爲 平滑，但是如第2圖（a)(b)所示，在主框架3的外周面設 · 有與容器胴體 2 1的內面之間形成預定寬的間隙的凹部 3 4，使此凹部3 4可被選擇作爲熔接處較佳。 凹部34，是如第2圖（a)所示，沿著主框架3的外周 面的圓周方向的一連的環狀溝也可以，如第2圖（b)所 示，沿著主框架3的外周面的圓周方向部分地形成溝也可 以。無論如何，藉由將凹部3 4作爲熔接處，所可使由熔 接所產生的變形退避至凹部3 4。然而，凹部3 4的寬（深 度）過大的話會成爲飛濺混入等的不良原因，所以凹部3 4 -11 - 200523477 (9) 的寬是〇. 1〜0.3 m m程度較佳。 壓縮部4，是由固定渦卷4 1及繞轉渦卷42的組合體 而成。固定渦卷4 1，是具有一體地形成於圓盤狀的鏡板 4 1 1的下面的渦捲狀的渦卷搭接板4 1 2，在其幾乎中央設 有供吐出由內部生成的高壓冷媒用的吐出口 4 1 3。 繞轉渦卷42，是具有一體地形成於圓盤狀的鏡板421 的上面的渦捲狀的渦卷搭接板422，在鏡板421的裏面中 央，形成可供軸 6的曲柄軸 6 2插入的圓筒狀的轂部 φ 423。藉由相互嚙合此固定渦卷41及繞轉渦卷42的各渦 卷搭接板4 1 2、422彼此，在內部形成冷媒壓縮用的密閉 作動室。 在固定渦卷4 1的裏面側（在反繞轉渦卷4 2側，第1 圖中的上面），是形成在壓縮元件的水平校正過程中所使 用的水平基準面43。水平基準面43，雖是設置於固定渦 卷的中央部分較佳，但是在外周側設成環狀也可以。 在主框架3及固定渦卷4 1，分別設置將壓縮部4固 · 定於主框架3用的螺栓孔3 4、44，在渦卷搭接板4 12、 422的調芯作業後，藉由螺栓8固定各螺栓孔34、44彼 此。 電動機5，是使用具備沿著容器胴體2 1的內周面安 裝的固定子5 1、及與同固定子5 1的中心同軸配置的轉子 5 2內轉子型的電動機，在轉子5 2的中心，軸6是藉由例 如熱壓嵌合被安裝成一體。 軸6，是具備：安裝有轉子5 2的主軸6 ；!、及在偏心 -12- (10) (10)200523477 於主軸6 1的上端側的狀態下一體地形成下曲柄軸6 2。在 此例中，曲柄軸6 2，是形成比主軸6 1的外徑（旋轉半徑） 更伸出外側。 因此，因爲無法使曲柄軸6 2對於主框架3的第1圖 從下側插通，所以在此例中，將壓縮部4組裝於主框架3 組成壓縮元件之前，需要將軸6插通主框架3的主軸承 3卜 副框架7，是具有使外周沿著容器胴體2 1的內周面 鲁 被固定的圓盤狀的框架，在其中央形成供軸支軸6的主軸 6 1的他端側用的副軸承7 1。在副框架7的下面（反電動機 5側，在第1圖中的下面），是形成在副框架7的水平校 正過程中所使用的水平基準面72。 上述結構的渦卷式壓縮機1 0的組裝，是使用接著說 明的組裝裝置的一例。第3圖（a)及（b)，是其組裝裝置的 前視圖及側面圖，圖中一點鎖線所示的X-X線，是組裝 好的渦卷式壓縮機1 0的旋轉中心，以下此χ-χ線稱爲壓 參 縮機中心線。 此組裝裝置200是具有由金屬材構成的框架構造，具 備：對於地面等的基礎水平設置的底基2 ；[ 〇、及從底基 210幾乎垂直立設的支撐框架220。在底基210中，設有 供組裝上述渦卷式壓縮機1 0用的作業台2 3 0。 在作業台23 0中，設有載置了壓縮元件1〇〇(事先組 裝了主框架3、壓縮部4及軸6的壓縮元件）的壓縮元件 固定台3 0 0。如第4圖所示，壓縮元件固定台3〇〇是具備 -13- 200523477 (11) 水平設置於作業台2 3 0上的例如形成圓盤狀的固定底基 3 1 0，在固定底基3 1 0的中央，是設有使固定渦卷4 1側朝 下向的方式載置壓縮元件100的載置台320。 載置台320，是形成於使固定底基310的中央部分高 出1段，在其上面設有供水平校正壓縮元件1 0 0用的水平 基準面3 2 1。固定渦卷4 1的水平基準面4 3是組裝於此水 平基準面321上。藉由此水平基準面321及水平基準面 4 3的2個面來保證壓縮元件1 〇 〇的水平狀態。 鲁 在壓縮元件固定台300中，設有供固定置於載置台在 3 2 0的壓縮部元件1 0 0的壓縮元件固定手段3 3 0。如第4 圖所示，壓縮元件固定手段3 0 0，是具備供挾持壓縮元件 1 0 0的固定渦卷4 1的外周面的挾盤爪3 3 1。 在此例，挾盤爪3 3 1，是在以上述壓縮機中心線x -x 爲中心的圓周上以9 0。間隔4處配置，分別藉由無圖示的 驅動手段沿著半徑方向移動可能。然而，挾盤爪3 3 1是2 個以上的話，其數量可任意決定。 φ 藉由此複數挾盤爪331，在載置台320上對位使壓縮 元件1 00的軸線（軸主軸6 1的旋轉軸線）是與上述壓縮機 中心線X-X線一致，如第5圖（a)所示，藉由無圖示的驅 動手段使各挾盤爪331朝垂直方向昇降可能，並且在各挾 盤爪3 3 1的先端設置卡止鉤3 3 2，在固定渦卷4 1的外周 面形成藉由卡止鉤3 3 2卡止的挾盤溝4 1 4，對位後使壓縮 元件1 0 〇朝載置台3 2 0側按壓固定較佳。 另外，如第5圖（b)所示，在固定渦卷41的外周面的 -14 -

Description of the invention [Technical field to which the invention belongs] The present invention relates to a method of assembling a scroll compressor '. In further detail, it is a container in which a main frame supporting a compression portion of a refrigerant is installed in a closed container. In the body, the manufacturing deformation of the container body is corrected, and the assembly method of the scroll compressor in which the compression part is installed in the container body while performing the alignment is corrected. [Prior art] Scroll compressors are known in which crescent-shaped compression is formed by engaging two scroll-shaped scroll overlap plates composed of a fixed scroll and an orbiting scroll to each other and forming a crescent-shaped compression. The space compresses the refrigerant based on the principle of orbiting the orbiting scroll to orbiting the orbiting scroll to reduce the volume of the compression space as it gradually decreases from the outside of the honing to the center. An example of the internal structure of a scroll compressor is shown in Fig. 9 and will be described below. This scroll compressor 1 is provided with a main frame 3 inside a cylindrical closed container 2 which is vertically arranged. A compression portion 4 is provided on the upper side of the main frame 3, and the compression portion 4 has a fixed scroll. 41 and the orbiting scroll 42 are provided on the lower side of the main frame 3 with a motor 5 that drives the compression unit 4 via a shaft 6. The main frame 3 is provided with a main bearing 31 for one end side of the main shaft 6 1 of the fulcrum shaft 6, and a sealed bearing 2 is further provided with a sub bearing for the other end side of the main shaft 6 1 of the fulcrum shaft 6. 7 1 of the sub-frame 7. A motor 5 is provided between the main frame 3 and the sub-frame 7, and the motors 5 -4-(2) (2) 200523477 are provided with: a holder 51 fixed to the inner peripheral surface of the container body 21; The rotor 52 inside the child 51 is integrally attached to the shaft 6. The main frame 3 and the sub-frame 7 are welded and fixed to the container body 2 1 ′. When both are welded, it is necessary to fix the axes of the main bearing 31 and the sub-bearing 71 in a mutually aligned manner. In other words, if the misalignment of the shaft centers of the main bearing 31 and the sub bearing 71 is large, the load φ of the single-point contact motor 5 caused by each of the bearing portions 31 and 71 will increase. In addition, the balance of the magnetic gap between the stator 5 1 and the rotor 5 2 may collapse, which may deteriorate the startability of the compressor. Here, Patent Document 1 (Japanese Patent No. 3 25 0 438) discloses an example of a method of welding and fixing the container body 21 with high accuracy in accordance with the axis of the main frame 3 and the sub-frame 7. In the method of assembling this patent document 1, first, as shown in FIG. 10 (a), the main frame 3 is placed on the horizontal reference surface 81 of the fixed base 8 and aligned with the pan claw 82, and then borrowed. The container body 21 in which the holder 51 is previously installed is lowered toward the main frame 3 by the lifting means, and the main bearing 3 1 and the holder 5 1 are further fixed by the fixing means (none of which is shown), and the lower end side of the container body 2 1 is fixed. Fused to the main frame 3. Next, in the second process, as shown in FIG. 10 (b), the shaft 6 integrally mounted on the rotor 5 2 is mounted on the main shaft 3 of the main frame 3 through the inside of the container housing 21. In the third process, as shown in FIG. 10 (c), the sub-frame 7 held by the alignment device 9 is inserted from the upper end of the container body 21, and the sub-frame 7 is aligned, and the container body 21 is The upper end side is welded to the sub-frame 7. -5- 200523477 (3) After that, the compression section 4 of the main frame 3 is mounted in another process. Generally, a container body 21 used in a compressor has a deformation during processing because a thick steel plate is processed into a cylindrical shape. In most cases, it is not a perfect circle. Also, even a cylinder without a seam cannot be guaranteed to be perfectly round. In addition, the difference in solidification time due to welding may cause the container body 21 to be more skewed. Further, the welding of the main frame 3 and the sub-frame 7 may make the container body 21 more skewed. When the compression unit 4 is mounted on the main frame 3, it is necessary to align (align) the relative positions of the fixed scroll 41 and the orbiting scroll 42 in addition to the main frame 3 φ. In the case of core operation, in the above-mentioned Patent Document 1, the container frame 21 is first installed in the main frame 3, so the main frame 3 cannot be directly grasped, because the centering operation is performed based on the outer periphery of the container frame 21. So the accuracy is not very good. There are other problems. For example, the shaft 6 of Patent Document 1 mentioned above has the crank shaft 6 2 formed at the tip thereof within the rotation radius of the main shaft 61. Therefore, even if the main frame 3 is placed on the fixed base 8 In the above, the shaft 6 can also be inserted into the main bearing 31 of the main frame 3. However, because this shaft will obtain compression energy, the diameter of the main shaft 61 needs to be thickened. If the diameter is thickened, the sliding loss of the main bearing 31 will not only increase, the volume of the rotor 5 2 will decrease, and the power of the motor 5 will also be increased. decline. Here, although the performance is better because the crank shaft 62 is formed with a shaft that extends more outward than the rotation radius of the main shaft 61, when using this shaft, when the compression portion 4 is assembled before the main frame 3, Since it is necessary to insert another type of shaft through the main bearing 31 of the main frame 3 in advance, the assembly method of Patent Document 1 described in (6) 200523477 (4) cannot be applied. [Summary of the Invention] The present invention is intended to solve the above-mentioned problems, and an object thereof is to correctly align the deformation of the container body when the main frame supporting the compression portion of the refrigerant is installed in the container body of the closed container while correctly positioning the container body. The compression part is installed in the container body. It is another object of the present invention to assemble a compression element in which a compression portion and a main frame are previously assembled in a hermetically sealed container. In order to achieve the above object, the present invention is a method for assembling a scroll compressor, which includes a compression part having a fixed scroll and a scroll wrap in a sealed container, and the scroll scroll is driven by a shaft. A motor, a main frame having a main bearing capable of supporting one end of the main shaft of the shaft and supporting the compression portion, and a sub frame having a sub bearing for supporting the other end of the main shaft of the shaft, To implement the pre-assembly process, the assembly process includes assembling the compression part and the shaft compression element on the main frame to form the compression element, and integrally mounting the rotor of the motor on the main shaft of the shaft. Rotor installation process; and post-assembly process, which includes: a horizontal correction process of a compression element assembled on a compression element fixing table so that the compression element becomes horizontal so that the shaft becomes vertical; and Positioning and fixing the compression on the compression element fixing table such that the axis position of the shaft is on the center line of the compressor The compression element alignment process of the piece, and the container body supported by the container holding means so as to be coaxial with the axis of the shaft, and the compression element fixing table and the container holding means are relatively moved by the first pressing means 200523477 (5 ) Until the opening on the one end side of the container body is in contact with the compression element fixing table, press the compression element into the compression element in the opening on the one end side of the container body, and press the compression element into (1) Pressing means: The container body is pressed against the compression element fixing table in a state of a compression element welding process in which the container body is integrally welded to the compression element by a welding means. In the above-mentioned level correction process of the compression element, it is preferable that the horizontal reference plane is formed on the inner side of the fixed scroll by performing the horizontal calibration properly. φ and 'also includes a process of mounting the sub-frame in the present invention. That is, the post-assembly process further includes: a sub-frame leveling process of assembling the sub-frame to the sub-frame fixing table in a horizontal state; and making the sub-frame on the sub-frame fixing table by a sub-frame fixing means. Positioning the sub-frame alignment process of fixing the sub-frame so that its axis position is on the center line of the compressor; and relatively moving the sub-frame fixing table and the container holding means by a second press-in means until the container body Pressing the sub-frame φ frame into the sub-frame opening in the other-end opening of the container body until the opening on the other end side abuts the sub-frame fixing table; and by the second pressing means In a state where the container body is pressed against the sub-frame fixing table, the container body is integrally welded to the sub-frame welding process of the sub-frame by welding means. For the above-mentioned sub-frame horizontal correction process, it is also preferable that the horizontal reference plane is formed on the back side of the above-mentioned sub-frame by performing the horizontal correction correctly '. In addition, the present invention includes an embodiment in which an electromagnet is provided on the sub-frame fixing table. -8- (6) (6) 200523477 According to a preferred aspect of the present invention, 'the alignment of the compression element is performed correctly'. The compression element fixing means includes a plurality of cymbal claws, which are equally spaced. The compressor is arranged on a circumference centered on the center line of the compressor, and is movable along the radial direction of the circle, and is engaged with the pan-ditch formed on the fixed scroll side. In addition, each of the cymbal disc claws can be raised and lowered in a vertical direction. During the lowering operation, it is preferable to press the compression element toward the compression element fixing table side through the cymbal disc groove. The portion engaged with the cymbal φ claw has a tapered surface that converts a horizontal force into a downward force. When the cymbal claw moves toward the inside in the radial direction, the compression element is pressed against the compression element by the cone surface. It is also possible to fix the side of the table. In the present invention, the main frame and / or the sub-frame are recessed portions having a predetermined width gap between the outer peripheral surface and the inner surface of the container body, and the recessed portions are selected as welding portions for the welding means. Better. According to this, welding deformation caused by welding can be retracted to the recessed portion. The concave portion may form a continuous φ annular groove along the circumferential direction of the outer peripheral surface. In another aspect, the concave portion may be partially formed along the circumferential direction of the outer peripheral surface. According to the present invention, the shaft includes a main shaft as an output shaft of the electric motor, and a crank shaft formed eccentrically to the main shaft and connected to the orbiting scroll. In the case of the outside, during the assembly of the compression element, the main shaft of the shaft is inserted into the main bearing of the main frame, the crank shaft is connected to the orbiting scroll, and the fixed scroll is mounted on the main shaft. frame. -9- (7) (7) 200523477 According to the present invention, by pressing the container body into the main frame, the container body can be closely fitted to the outer peripheral surface of the main frame even if the container body has manufacturing deformation. Together. The sub-frame side is also the same, so that the compression part can be installed in the container body while performing accurate alignment. Furthermore, since a shaft compression element in which a compression part, a main frame, and a motor are previously assembled can be assembled in a hermetic container, a scroll compressor having a shaft whose crank shaft is an outside of the outer diameter of the main shaft is also applicable. [Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. First, the cross-sectional view of Fig. 1 shows the internal structure of a scroll compressor assembled according to the present invention. Although this will be described, the present invention is not limited to this. However, the use of the same reference symbols is the same as or considered the same as the above-mentioned conventional examples.

However, the sealed container 2 also contains a power supply cable for driving the motor 5 and a lubricating oil. However, these are not important components of the present invention, so they are not shown in the drawings, and the description thereof is omitted. Also omitted. The hermetic container 2 includes a cylindrical container body 21 and an upper cover 22 and a lower cover 23 which are integrally attached to both end sides of the same container body 21. The container body 21 may be a cylindrical body in which a thick steel plate is processed into a cylindrical shape and both ends are welded, or a cylindrical body without a seam may be welded. The upper cover 22 and the lower cover * 10- (8) (8) 200523477 2 3 are welded to the container body 2 1 in the final process. The main frame 3 is a main frame 31 having a disc-shaped frame having a substantially circular shape on the outer periphery, and a main shaft 61 of a fulcrum shaft 6 formed at the center. A receiving recess 32 is formed on the upper surface side of the main frame 3, and a mirror plate 4 2 1 of the orbiting scroll 4 2 is accommodated by the rotation-preventing ondan ring 3 3. Since the main frame 3 is pressed into the container body 21, its outer diameter is formed to be slightly larger than the inside diameter of the container body 21. The lower part of the storage recess 32 is formed at the lower part, and the crank shaft 6 2 of the shaft 6 and the hub 4 2 3 of the orbiting scroll 4 2 are accommodated in a state where the orbiting motion is possible. In addition, the main frame 3 is provided with an oil discharge passage (not shown) for returning the lubricating oil supplied to the upper portion of the main frame 3 to the bottom side of the hermetic container 2 through an oil guide hole 63 formed in the shaft 6. In the case of an internal high-pressure type, an unillustrated refrigerant passage for guiding the high-pressure refrigerant generated in the sealed operating chamber of the compression section 4 to the motor chamber is provided in the main frame 3. The main frame 3 is formed by, for example, cutting, and although the outer peripheral surface is smooth, as shown in Fig. 2 (a) (b), an inner surface of the main frame 3 is provided with the container body 21 A recessed portion 34 is formed with a predetermined wide gap between the surfaces, so that this recessed portion 34 can be selected as a welding place. The recessed portion 34 may be a continuous annular groove along the circumferential direction of the outer peripheral surface of the main frame 3 as shown in FIG. 2 (a), and may be formed along the main frame 3 as shown in FIG. 2 (b). The groove may be partially formed in the circumferential direction of the outer peripheral surface. In any case, by using the recessed portion 34 as a welding place, the deformation caused by the welding can be retracted to the recessed portion 34. However, if the width (depth) of the recessed portion 34 is too large, it may cause undesirable effects such as splashing and mixing. Therefore, the width of the recessed portion 3 4 -11-200523477 (9) is 0. 1 ~ 0. 3 mm is better. The compression portion 4 is a combination of a fixed scroll 41 and an orbiting scroll 42. The fixed scroll 41 is a scroll-shaped scroll splicing plate 4 1 2 which is integrally formed on the lower surface of the disc-shaped mirror plate 4 1 1, and a high-pressure refrigerant generated inside is provided at a substantially center thereof. Used spit outlet 4 1 3. The orbiting scroll 42 has a scroll-shaped scroll overlap plate 422 integrally formed on the upper surface of the disc-shaped mirror plate 421, and a crank shaft 62 for inserting the shaft 6 is formed in the center of the inner surface of the mirror plate 421. The cylindrical hub φ 423. The scroll wrap plates 4 1 2 and 422 of the fixed scroll 41 and the orbiting scroll 42 are meshed with each other to form a closed operating chamber for refrigerant compression inside. On the inner side of the fixed scroll 41 (on the side of the anti-revolving scroll 4 2, the upper side in FIG. 1), a horizontal reference plane 43 used in the horizontal correction process of the compression element is formed. Although the horizontal reference plane 43 is preferably provided in the center portion of the fixed scroll, it may be provided in a ring shape on the outer peripheral side. Bolt holes 3 4 and 44 for fixing and fixing the compression portion 4 to the main frame 3 are provided in the main frame 3 and the fixed scroll 41, respectively.

And an eccentric -12- (10) (10) 200523477 on the upper end side of the main shaft 61 to form a lower crank shaft 62 integrally. In this example, the crank shaft 62 is formed so as to protrude further than the outer diameter (rotation radius) of the main shaft 61. Therefore, because the crank shaft 62 cannot be inserted from the lower side of the first frame of the main frame 3, in this example, before assembling the compression portion 4 to the main frame 3 to form a compression element, the shaft 6 needs to be inserted into the main frame. The main bearing 3 and the sub-frame 7 of the frame 3 are disc-shaped frames whose outer periphery is fixed along the inner peripheral surface of the container body 21, and a main shaft 6 1 for the shaft 6 is formed in the center of the disc-shaped frame.

The lifting base 510 supports a push-in head 520 as a jig for pressing the container body φ 21 from above. As shown in FIG. 4, the push-in head 520 is formed by a disc body that is horizontally mounted on the lifting base 510, and a horizontal pressing surface that acts on the upper end 2 1 2 of the container body 21 is formed on its peripheral edge portion. 5 4 0. In this example, the press-in head 5 2 0 also serves as a sub-frame fixing table. A sub-frame fixing table 530 for supporting the sub-frame 7 is provided at the center of the press-in head 5 20. The sub-frame fixing table 530 is formed to be one step higher than the peripheral pressing surface 540 so that it can enter the container body 21. The supporting surface of the sub-frame 7 is a horizontal state of the sub-frame 7 as a sub-frame pressing process described later. The horizontal reference surface 5 3 1 for support is formed flat. In the central portion of the sub-frame fixing table 5 30, a recessed portion 5 50 for the sub-bearing 7 1 of the sub-frame 7 is retracted. A sub-frame fixing means 5 60 is arranged in the recessed portion 5 50. The sub-frame fixing means 5 60 is provided with a plurality of disk claws 5 6 1 similar to the disk claws 3 3 1 described by the compression element fixing means 3 3 0 described above. That is, each cymbal disc claw 5 6 1 is preferably arranged at equal intervals on a circle centered on the compressor centerline X-X, and reciprocates along its circular -16- (14) 200523477 radius line. Movement is possible. In addition, the sub-frame fixing table 5 3 0 is constructed by a magnetic body. An electro-magnet is provided in the sub-frame fixing table 5 30.

As shown in FIG. 3 (a) and (b), in this assembly device 200, the container body 21 is welded to the compression element 100 and the sub frame 7 section 6 0 0. In this example, the welding means 6 0 0 is arranged on the circumference centered on the above-mentioned pressure X-X at, for example, 4 intervals of 90 °, and the number of welding torches 6 1 0 610 that can move in the radial direction of the circle can be arbitrarily determined. In this example, each of the welding torches 6 1 10 can move along the supporting frame. Although it operates for the welding position of the compression element 100 and for the auxiliary welding position, it is possible to arrange welding at each welding position. The support frame 220 is further provided with a control instrument panel 2 1 0 for controlling the compression section 330, the container holding means 400, and the pressing means 500 6 0 0. A control monitor 2 1 10 is provided with a display monitor or various operation panels, and the input can be used to set, for example, the press pressure. In this example, the compression element fixing table 300 is fixed, although the holding means 4 0 0 and the pressing means 5 0 0 are respectively provided in the present invention, the compression element fixing table 300 and the container holding hand insertion means 5 0 0 As long as it can be set relatively, it can be compressed into a coil.

Next, an example of an assembling procedure of the scroll compressor 10 using the above-mentioned assembling device 200 will be described with reference to FIGS. 6 to 8. First, a pre-assembly process which is to be carried out as a pre-assembly of the scroll compressor 100 by the above-mentioned assembling apparatus 200 will be described. In the previous assembly process, the assembly process including assembling the compression part 4 and the shaft 6 to the main frame 3 to form the compression element 100 and the compression element, and the rotor 5 2 of the motor 5 integrally mounted on the shaft 6 The rotor mounting process of the main shaft 61 and the stator mounting process of mounting the stator 51 of the electric machine 5 integrally in the container body 21 of the closed container 2. In the assembly process of the compression element, the main shaft 61 of the shaft 6 is inserted into the main bearing 3 1 of the main frame 3, and the crank shaft 6 2 is connected to the hub 42 3 of the orbiting scroll 4 2, and then the fixed scroll 4 1 is fixed. Attach to the main frame 3. According to this example, the shaft 6 is a crank. The shaft 62 is formed to protrude outside than the outer diameter of the main shaft 6 I. Therefore, although the shaft 6 needs to be mounted on the main frame 3 first, a crank is provided in the outer diameter of the main shaft 61. In the case of the shaft 62, the compression portion 4 may be assembled to the main frame 3, and then the shaft 6 may be inserted into the main bearing 31 of the main frame 3. After the assembly of the compression element is completed, the relative honing positions of the orbiting scroll 41 and the orbiting scroll 42 are positioned (g-peripheral core) by the g-core process of the compression element having a centering device (not shown). In addition, the rotor mounting process is performed using a dedicated rotor mounting device. In this example, the 'rotor 52' is mounted integrally by thermocompression fitting of the main shaft 61 of the compression element 100. The fixture mounting process is also performed using a dedicated fixture mounting device. In this example, the fixture -18- 200523477 (16) 51 is also fitted into the inner surface of the container body 21 by heat pressing to be integrated. However, the fixer installation process may not be performed before the assembly process, but may be performed after the assembly process described below. Next, the above-mentioned assembling device 2000 is used to assemble the compression element 100 having been completed in the pre-assembly process in the container body 21. Among them, first, the container body 21 is held by each container holding arm 420 of the container holding means 400 (the container body mounting process). Before and after this, as shown in Fig. 6, the compression element 100 is turned upside down and placed on the mounting table 3 20 of the compression element fixing table 300. The compression element 100 is set horizontally correctly by fixing the two horizontal reference planes 4 3 on the scroll 41 1 side and the horizontal reference plane 3 2 1 on the mounting table 3 2 0 side. 6Orientation in the vertical direction (the horizontal correction process of the compression element). Next, each of the cymbal claws 3 3 1 is moved toward the compressor centerline X-X so that the axis of the compression element 100 (the rotation axis of the shaft main axis 61) is aligned with the compressor centerline XX (the compression element Alignment process). Next, the container holding means 4 is lowered, and the lowering is temporarily stopped when the lower spring end 2 1 1 of the container body 21 abuts the edge of the main frame 3. Instead of this, the pressing head 5 2 0 is lowered, and the upper surface 212 of the container body 21 is pressed by the pressing surface 5 40 to further lower the container body 21, and the compression element 3 00 is pressed into the container body 21. This press-in is performed until the lower end 21 1 of the container body 2 1 abuts on the receiving table 3 4 1 of the compression element fixing table 3 0 0 (compression element pressing process). When the compression element pressing process is completed, the container body 2 1 is kept pressed against the receiving stage 3 4 1 by the pressing head 5 20, and the welding is performed directly by electric arc-19- (17) (17) 200523477 Each welding torch 6 i 0 of the means 600 is moved to the side of the main frame 3, and the container body 2 1 is integrally welded to the main frame 3 of the compression element 100 (the compression element welding process). However, by forming the above-mentioned recessed portions 34 on the outer peripheral surface of the main frame 3, the press-in load can be reduced, and deformation during welding can also be absorbed. When the welding process of the compression element is completed, the press-in head 520 is raised to the initial position, and then the assembly process of the sub-frame 7 is started. However, for the assembling operation of the sub-frame 7, the compression element 100 side is also fixed by the disk claw 3 3 1 φ. Referring to FIG. 7, the sub-frame 7 is attached to the sub-frame fixing base 5 3 0 of the press-in head 5 2 0 at the initial position. When the sub-frame 7 is installed, the horizontal reference plane 5 3 1 formed on the sub-frame fixing table 5 3 0 and the horizontal reference plane 7 2 1 of the sub-frame 7 can be accurately aligned (the sub-frame horizontal correction). process). Next, 'moving each of the panning claws 5 6 1 of the sub-frame fixing means 5 60 inward and holding the sub-bearing 7 1 of the sub-frame 7 so that its axis line is aligned with the above-mentioned compression axis center line XX, and then energized to An electromagnet wire (not shown) magnetically fixes the sub-frame 7 to the sub-frame fixing table 5 3 0 (sub-frame alignment process). Then, as shown in FIG. 8, the push-in head 5 2 0 is lowered, and the sub-frame 7 is gradually pushed in from the upper end 2 1 2 side of the container body 2 1, and is pressed on the pressing surface 5 4 0 of the push-in head 5 20. When the upper end 2 1 2 of the container body 2 abuts, the press-in is stopped (the sub-frame press-in process). Next, without releasing the pressing force of the pressing head 5 2 0, the welding means -20- (18) (18) 200523477 600 is moved to each welding torch 6 1 0 until the opposite side faces the side surface of the sub-frame 7. The container body 2 1 is integrally welded to the sub-frame 7 (sub-frame welding process). However, it is preferable to form recesses 34 similar to those of the main frame 3 on the outer peripheral surface of the sub-frame 7 except for reducing the pressing load and absorbing deformation during welding. Through the above-mentioned continuous process, the sub-frame 7 is assembled to the container body 21. When the assembly operation is completed, release the claws 3 3 1, 5 6 1. Restriction of each container holding arm 420, raise the pressing head 520 to the initial position, and take out the compressor from the compression element fixing table 3 00 to power Wiring or piping. Furthermore, if the operation test is finally performed to determine that there are no problems, the upper lid 22 and the lower lid 2 3 are individually welded to both ends of the container body 21 to form a completed body. As described above, according to the present invention, the main frame 3 and the sub-frame 7 are pressed into the container body 21 of the hermetic container (closed cover) 2 and the horizontal reference plane (assembly standard of the main frame 3 and the sub-frame 7) is pressed. Surface) 4 3, 72 and the open end face of the container body 21 (lower end 21 1, upper end 212). Pressing and welding the fixing jigs (compression element fixing table 300, sub-frame fixing table 530, etc.) in the same direction can ensure the main The parallelism of the frame 3 and the sub-frame 7 can correctly match the axis of the main bearing 31 and the sub-bearing 71. Therefore, it is possible to prevent the single point contact of each bearing portion caused by the axial center deviation of the main bearing 31 and the sub-bearing 71 and the non-uniformity of the magnetic interval of the motor 5, thereby improving the performance and reliability of the compressor. In addition, the assembly method of the present invention is a scroll compressor having a crankshaft that is a shaft that protrudes toward the outside of the outer diameter of the main shaft (refer to FIG. 1), and the shaft needs to be -21-(19) (19) 200523477. A compressor that is inserted through the main frame and directly locates the inner diameter of the main bearing and the stator and cannot be welded can also be applied. In addition, since the compression element that has been centered) assembled in the sub-process (pre-assembly process) can be incorporated into the container body, the division of labor for assembly is possible. The preferred embodiment of the present invention has been described above with reference to the accompanying drawings. However, the present invention is not limited to this embodiment. Those skilled in the art who have general technical knowledge in the field of assembling methods of scroll compressors can easily think of various modifications or amendments within the scope of the technical ideas in the scope of patent application.
