　しかしながら、特許文献１のアキュムレータ固定装置で締結部材を用いた場合、アキュムレータ固定装置の部品数が多くなり、製造工程も多くなるため、密閉型圧縮機の製造コストが高くなるという課題があった。また、特許文献１においてアーク溶接等の溶接を用いた場合には、アキュムレータ固定装置をアキュムレータに取り付ける溶接時間が長くなり、溶接時の加熱範囲が広くなる。したがって、特許文献１においてアーク溶接等の溶接を用いた場合には、アキュムレータの筐体等の母材が減肉し、アキュムレータの強度が低減することにより、密閉型圧縮機の強度に対する信頼性を確保できない可能性があるという課題があった。また、例えば、特許文献１においてＴＩＧ溶接等のアーク溶接を用いた場合には、シールドガス又は溶加棒等の副資材が必要となるため、密閉型圧縮機の製造コストが高くなるという課題があった。 However, when the fastening member is used in the accumulator fixing device of Patent Document 1, the number of parts of the accumulator fixing device is increased and the number of manufacturing processes is increased, which causes a problem that the manufacturing cost of the hermetic compressor is increased. Moreover, when welding, such as arc welding, is used in Patent Document 1, the welding time for attaching the accumulator fixing device to the accumulator becomes longer, and the heating range during welding becomes wider. Therefore, when welding such as arc welding is used in Patent Document 1, the base material such as the accumulator housing is thinned, and the strength of the accumulator is reduced. There was a problem that there was a possibility that it could not be secured. In addition, for example, when arc welding such as TIG welding is used in Patent Document 1, additional materials such as a shielding gas or a filler rod are required, which increases the manufacturing cost of the hermetic compressor. there were.
　また、特許文献２及び特許文献３におけるプロジェクション溶接では、プロジェクション溶接時の加圧により、溶接用の突起と被溶接物との接触部分にずれが生じる場合がある。したがって、特許文献２及び特許文献３におけるプロジェクション溶接では、溶接用の突起と被溶接物との接触部分で溶接不良が生じ、密閉型圧縮機の強度に対する信頼性を確保できない可能性があるという課題があった。 Further, in the projection welding in Patent Document 2 and Patent Document 3, there is a case where the contact portion between the welding projection and the workpiece to be welded is displaced by pressurization at the time of projection welding. Therefore, in the projection welding in Patent Literature 2 and Patent Literature 3, there is a possibility that poor welding occurs at the contact portion between the welding projection and the work piece, and the reliability with respect to the strength of the hermetic compressor may not be ensured. was there.
　本発明は、上述の課題を解決するためのものであり、強度に対する信頼性を確保可能であり、かつ、製造コストを低減可能な気液分離器固定具、密閉型圧縮機、密閉型圧縮機の製造装置、及び密閉型圧縮機の製造方法を提供することを目的とする。 The present invention is intended to solve the above-described problems, and it is possible to ensure reliability with respect to strength and to reduce a manufacturing cost.

　本発明に係る気液分離器固定具は、密閉型圧縮機の密閉容器に気液分離器を固定するための気液分離器固定具であって、前記密閉容器に固定される固定部と、前記固定部から延在し、前記気液分離器を支持する支持部と、前記支持部に配置され、前記気液分離器を拘束する複数の突起部とを備える。 A gas-liquid separator fixture according to the present invention is a gas-liquid separator fixture for fixing a gas-liquid separator to a sealed container of a hermetic compressor, and a fixing part fixed to the sealed container; A support portion extending from the fixed portion and supporting the gas-liquid separator; and a plurality of protrusions disposed on the support portion and restraining the gas-liquid separator.
　また、本発明に係る密閉型圧縮機は、上述の気液分離器固定具を備える。 Moreover, the hermetic compressor according to the present invention includes the gas-liquid separator fixture described above.
　また、本発明に係る密閉型圧縮機の製造装置は、上述の気液分離器固定具に配置された前記気液分離器を、前記気液分離器固定具の前記突起部に圧力を印加して拘束させる加圧シリンダと、前記突起部に電流を流して前記突起部を溶かし、前記気液分離器を前記気液分離器固定具に固定させる複数の電極とを備える。 The manufacturing apparatus for a hermetic compressor according to the present invention applies pressure to the protrusion of the gas-liquid separator fixture by applying the gas-liquid separator arranged in the gas-liquid separator fixture. And a plurality of electrodes for causing a current to flow through the protrusions to melt the protrusions and fixing the gas-liquid separator to the gas-liquid separator fixture.
　また、本発明に係る密閉型圧縮機の製造方法は、上述の気液分離器固定具に前記気液分離器を配置する工程と、前記突起部に圧力を印加して前記気液分離器を前記突起部で拘束する工程と、前記突起部に電流を流して前記突起部を溶かし、前記気液分離器を前記気液分離器固定具に固定させる工程とを含む。 The method for manufacturing a hermetic compressor according to the present invention includes a step of arranging the gas-liquid separator in the gas-liquid separator fixture described above, and applying the pressure to the protrusion to The step of restraining by the protrusion, and the step of passing an electric current through the protrusion to melt the protrusion and fixing the gas-liquid separator to the gas-liquid separator fixture.

　密閉型圧縮機１００の製造装置２００では、気液分離器固定具７０の４つの突起部７６でサクションマフラ６０が拘束されているため、加圧シリンダ７９で突起部７６に圧力を印加した場合であっても、サクションマフラ６０が移動するのを防止することができる。したがって、密閉型圧縮機１００の製造装置２００では、サクションマフラ６０の移動を防止することにより、突起部７６のサクションマフラ６０への接触不良を防ぎ、溶接不良を回避することができる。 In the manufacturing apparatus 200 of the hermetic compressor 100, the suction muffler 60 is restrained by the four protrusions 76 of the gas-liquid separator fixture 70, and therefore when the pressure is applied to the protrusion 76 by the pressure cylinder 79. Even if it exists, it can prevent that the suction muffler 60 moves. Therefore, in the manufacturing apparatus 200 of the hermetic compressor 100, by preventing the movement of the suction muffler 60, it is possible to prevent poor contact of the protrusions 76 with the suction muffler 60 and avoid poor welding.
　これに対し、気液分離器固定具７０の第１の支持部材７４ａ及び第２の支持部材７４ｂに突起部７６を１つずつしか設けなかった場合を考える。図７は、本実施の形態１に係る密閉型圧縮機１００の製造装置２００において、気液分離器固定具７０の第１の支持部材７４ａ及び第２の支持部材７４ｂに突起部７６を１つずつ設け、加圧シリンダ７９で突起部７６に圧力を印加した状態を示す概略図である。図７では、圧力が印加された突起部７６を領域Ｂとして点線で囲っている。また、図７では、加圧シリンダ７９の加圧方向を黒矢印で示している。図８は、図７における圧力印加後の状態の一例を示す概略図である。
On the other hand, consider a case where only one protrusion 76 is provided on each of the first support member 74 a and the second support member 74 b of the gas-liquid separator fixture 70. 7 shows a manufacturing apparatus 200 for a hermetic compressor 100 according to the first embodiment. One protrusion 76 is provided on each of the first support member 74a and the second support member 74b of the gas-liquid separator fixture 70. FIG. FIG. 5 is a schematic view showing a state in which pressure is applied to the protrusion 76 by the pressurizing cylinder 79 one by one. In FIG. 7, the protrusion 76 to which pressure is applied is surrounded by a dotted line as a region B. In FIG. 7, the pressure direction of the pressure cylinder 79 is indicated by a black arrow. FIG. 8 is a schematic diagram illustrating an example of a state after application of pressure in FIG.
　図７の領域Ｂに示すように、気液分離器固定具７０の第１の支持部材７４ａ及び第２の支持部材７４ｂに突起部７６を１つずつしか設けなかった場合、加圧シリンダ７９で突起部７６に圧力を印加した際に、図８に示すように、サクションマフラ６０の移動を防止できない可能性がある。図８に示すように、サクションマフラ６０の位置が移動した場合、突起部７６のサクションマフラ６０への接触不良が生じ、溶接不良が発生する可能性がある。 As shown in region B of FIG. 7, when only one protrusion 76 is provided on each of the first support member 74 a and the second support member 74 b of the gas-liquid separator fixture 70, When pressure is applied to the protrusion 76, the movement of the suction muffler 60 may not be prevented as shown in FIG. As shown in FIG. 8, when the position of the suction muffler 60 is moved, poor contact of the protrusions 76 with the suction muffler 60 may occur, resulting in poor welding.
　したがって、密閉型圧縮機１００の製造装置２００では、気液分離器固定具７０の４つの突起部７６でサクションマフラ６０を拘束することにより、突起部７６のサクションマフラ６０への接触不良を防ぎ、溶接不良を回避することができる。 Therefore, in the manufacturing apparatus 200 of the hermetic compressor 100, the suction muffler 60 is restrained by the four protrusions 76 of the gas-liquid separator fixture 70, thereby preventing poor contact of the protrusions 76 with the suction muffler 60, Welding defects can be avoided.

Restrained by the protrusion 76. In FIG. 9, the first electrode 80a is disposed on the outer surface side of the first support member 74a, and the second electrode 80b is disposed on the outer surface side of the second support member 74b. By pressurizing the first electrode 80a in the direction of the second electrode 80b, the first protrusion 76a, the second protrusion 76b, the third protrusion 76c, and the fourth protrusion 76d are suction mufflers. The housing 62 of the suction muffler 60 is restrained by contacting the housing 62 of the 60. By applying pressure and restraining the suction muffler 60 on the protrusion 76, it is possible to avoid the displacement of the suction muffler 60 in the x direction during the manufacture of the hermetic compressor 100.
　次いで、本実施の形態１に係る密閉型圧縮機１００の製造方法においては、第１の電極８０ａ及び第２の電極８０ｂを用いて、突起部７６に電流を流して突起部７６を溶かし、サクションマフラ６０を気液分離器固定具７０に固定させる。本実施の形態１に係る密閉型圧縮機１００の製造方法においては、サクションマフラ６０のｘ方向へのずれを突起部７６への加圧により回避できるため、サクションマフラ６０の筐体６２と気液分離器固定具７０との溶接不良を回避することができる。 Next, in the manufacturing method of the hermetic compressor 100 according to the first embodiment, using the first electrode 80a and the second electrode 80b, current is passed through the protrusion 76 to melt the protrusion 76, and the suction is performed. The muffler 60 is fixed to the gas-liquid separator fixture 70. In the manufacturing method of the hermetic compressor 100 according to the first embodiment, since the displacement of the suction muffler 60 in the x direction can be avoided by pressurizing the protrusion 76, the casing 62 and the gas-liquid of the suction muffler 60 can be avoided. A welding failure with the separator fixture 70 can be avoided.
