[0065] The positioning device 40 according to the first embodiment of the present invention and the positioning method of the fixed scroll 34 implemented by the positioning device 40 will be described.

[0066] (fixed scroll positioning device)

[0067] The positioning device 40 of this embodiment is used for positioning the fixed scroll 34 during the assembly of the scroll compressor 10 . Specifically, the positioning device 40 is optimized for adjusting the position of the fixed scroll 34 when the fixed scroll 34 is installed on the assembly 11 formed during the assembly process of the scroll compressor 10 The positional relationship between the fixed scroll 34 and the movable scroll 31 is used.

[0068] As a supplementary note, the assembly 11 is composed of the main body part 16, the casing 36, the compressor motor 25, the lower bearing part 23, the crankshaft 20 and the movable scroll 31 as a whole. In this assembly 11 , the casing 36 , the compressor motor 25 , and the...

Abstract

In a positioning apparatus (40), a fixed scroll (34) is positioned with respect to an assembly body (11) in which a compressor motor (25) has been incorporated. In positioning the fixed scroll (34), electric power is supplied to the compressor motor (25) from an inverter (81) to rotate a crank shaft (20) by the compressor motor (25), thereby shifting a movable scroll (31). In the positioning apparatus (40), the shift of the movable scroll (31) leads to calculation of an appropriate position of the fixed scroll (34). A striking unit (70) applies impact force to the fixed scroll (34) to stir thefixed scroll (34) to the appropriate position.

Description

technical field [0001] The invention relates to a method and a device for positioning a fixed scroll when assembling a scroll compressor. Background technique [0002] Hitherto, a scroll fluid machine has been widely used as a compressor or the like which is installed in a refrigerant circuit of an air conditioner or the like to compress refrigerant. In a scroll fluid machine, the spiral scrolls are respectively arranged in the fixed scroll and the movable scroll, and the scroll on the side of the fixed scroll and the scroll on the side of the movable scroll are meshed with each other. to form a fluid chamber. In this scroll fluid machine, the volume of the fluid chamber changes as the movable scroll orbits. For example, in a scroll compressor, the volume of the closed fluid chamber is gradually reduced to compress the fluid in the fluid chamber. [0003] As described above, in a scroll type fluid machine, the movable scroll orbits in a state where the wrap of the movable...
