主机架作为压缩机的主要结构，固定在压缩机机壳的内壁面，并可用于支撑涡旋动盘和固定涡旋静盘，所以压缩机对主机架的定位精度要求极高。
相关技术中，通过主机架上的螺栓孔锁紧限制主机架焊接过程的轴向位移，主机架内部圆柱孔与工装配合限制径向位移。这种定位方法需要外围螺纹和内部圆柱孔同时满足工装，并且需要工作人员多次操作调整，工作效率低下，严重影响压缩机的生产效率。

具体地，压缩机对于主机架的定位精度要求极高。本申请提出的压缩机在装配过程中，将工装伸入到导向结构的内部。工装本身是一个可伸缩的结构，可采用液压等方式进行驱动。当工装伸入到导向结构内部后，驱动工装展开，此时工装与导向结构的内壁紧密贴合，通过工装和导向结构的配合实现对主机架的精准定位，保证了主机架在机壳内部的精确位置，能够保证压缩机的装配精度，并且保证了主机架与机壳内壁的相对位置稳定，进而使得工作人员可进行后续安装工作。
此外，由于工装与导向结构的良好配合，工作人员仅需要一次操作即可实现对主机架的定位，工艺工序简单，可极大程度上提高压缩机的生产效率，进而降低压缩机的成本。也即，本申请提出的压缩机，通过导向结构与工装的配合，可有效简化主机架的定位工序，提升主机架的定位效率，便于工作人员装配作业。

特别地，上述操作工艺简单，仅需将工装通过导向腔进入到定心腔内部，并控制工装收缩或展开即可，一次操作即可完成。并且，导向腔和定位腔设置在主机架的本体的内部，对主机架的外部尺寸没有要求，可适用于不同规格尺寸的主机架，具有极强的通用性，有利于实现压缩机产品系列化设计。

进一步地，如图2所示，导向腔1044延伸到中心端面，导向腔1044与主机架104的支撑结构1054的外径同心设置；定心腔1046包括第一子腔体1048和第二子腔体1050，且第二子腔体1050的内壁1052倾斜设置；主机架104的导向腔1044和定心腔1046轴向顺序布置，导向腔1044轴向延伸与定心腔1046相连，第二子腔体1050的内壁1052位于第一子腔体1048和导向腔1044中间；如图3所示，第二子腔体1050的内壁1052倾斜角度部分，第二子腔体1050的内壁1052的母线所在的直线与中心轴线所在直线的夹角α大于5°；如图2所示，导向腔1044的径向尺寸L1小于定心腔1046的径向尺寸，其中，第一子腔体1048的径向尺寸L2最大，用于容纳装配工装。
传统主机架定位工艺需要多次工艺组装多个结合构件才能完成。与传统主机架的定位工艺相比，本具体实施例的主机架104的定位，只通过一次定位即可完成，工艺组装简单，可提高压缩机的生产效率。主机架104采用具有倾斜的内壁1052的第二子腔体1050定位，主机架104内圆柱孔尺寸容易保证，实现定位精度高，整机装配精度提高，有利于提升压缩机整机同轴度、提升压缩机的可靠性。并且，采用该工艺结构，对主机架104其他尺寸没有影响，有利于压缩机产品系列化设计。
具体实施例中，本实施例提出的压缩机为涡旋压缩机，涡旋压缩机具有涡旋齿的动涡旋盘和具有涡旋齿的静涡旋盘。动涡旋盘执行相对于静涡旋盘的绕动运动，当动涡旋盘和静涡旋盘彼此接合时，随着动涡旋盘执行 绕动运动，动涡旋盘和静涡旋盘之间所形成的压力室的容量被减少。因此，压力室中的介质的压力可被增加，并且介质从形成在静涡旋盘中央部分的排放口被排出。
静涡旋盘上形成背压调节室，该背压室具有处于排出压力和吸入压力之间的中间压力的背压室面。也就是说，通过背压调节室，动涡旋盘和静涡旋盘可以适当的力彼此接触，可以防止制冷剂泄漏并且可增加润滑，同时接触力可调节，接触的摩擦可被减少，但密封力却并未降低。
