Description
Technical field：
The present invention relates to a kind of compressor scroll mounting structure.
Background technology：
Existing spiral case is divided into upper and lower two parts, lower house and the positioning finger setting of casing circumferential registration, and upper shell is with
The positioning finger setting of housing circumferential registration, first loads casing during assembling by lower house, and the alignment of lower casing body opening has been installed on casing
Alignment pin, refill upper shell, the alignment pin on the hole alignment lower house of upper shell, refill bend return channel, finally put into gas
Road mounting seat.Axial restraint is to use screw in compression air intake duct mounting seat, bend return channel, upper shell and lower house, is reached axially
It is fixed.For the mounting structure of this kind of mode when assembling lower house, the hole of lower house will be directed at the alignment pin being installed on casing,
Because not seeing bad contraposition during installation, and O-ring seal is housed on lower house, it is not easy to rotate, so the hole of lower house is not
It is easy to align with being installed to the alignment pin on casing.
The content of the invention：
The present invention is to provide a kind of compressor scroll mounting structure to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of compressor scroll mounting structure, including upper shell, lower house, machine
Shell, alignment pin, the first screw, bend return channel, air flue mounting seat and the second screw, the lower house is in casing, upper casing
Body is connected on lower house by alignment pin, the first screw through upper shell and being threaded on casing, and by upper shell and
Lower house is positioned in casing, and for bend return channel in casing, air flue mounting seat is fixedly connected on casing by the second screw
In side wall, and one end of air flue mounting seat is stretched in casing, and bend return channel is contacted on upper shell.
Further, sealing ring is provided between the lower house and casing.
Further, the air flue mounting seat includes connecting portion and location division, and the connecting portion is fixed by the second screw
It is connected on chassis sidewall, location division is contradicted on bend return channel.
The present invention has the advantages that：The present invention cancels the alignment pin between lower house and casing, and upper shell is with the
One mode connects for screw upper shell and the positioning finger setting of lower house circumferential registration, the first screw in compression upper shell, is realized on casing
The axial restraint of upper and lower casing, good positioning effect, is easily installed.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is lower house installation diagram when in casing in the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention discloses a kind of compressor scroll mounting structure, including upper shell 11, lower house 12, casing
13rd, alignment pin 14, the first screw 15, bend return channel 16, the screw 18 of air flue mounting seat 17 and second, lower house 12 are located at casing
In 13, upper shell 11 is connected on lower house 12 by alignment pin 14, and the first screw 15 is through upper shell 11 and is threaded in
On the inwall of casing 13, and upper shell 11 and lower house 12 are axially positioned in casing 13.Bend return channel 16 is located at casing
In 13, air flue mounting seat 17 is fixedly connected in the side wall of casing 13 by the second screw 18, and one end of air flue mounting seat 17 is stretched
In in casing 13, and bend return channel 16 is contacted on upper shell 11.
To ensure sealing, sealing ring 19 is provided between lower house 12 and casing 13.
Air flue mounting seat 17 in the present invention includes connecting portion 171 and location division 172, and connecting portion 171 passes through the second screw
18 are fixedly connected in the side wall of casing 13, and location division 172 is contradicted on bend return channel 16.
Such as Fig. 2, when lower house 12 is arranged in casing 13, mounting blocks 100 and lower house 12 are first used into mounting screw
200 are connected, and mounting screw 200 is threaded in the mounting hole for installing alignment pin 14, and positioning screw 300 is connected to casing
On 13, positioning screw 300 is threaded in the mounting hole for connecting the first screw 15.Then housing 12, lower house are loaded
12 are attached to behind position and pull down mounting blocks 100, and installation alignment pin 14 simultaneously loads onto upper shell 11, and such lower house 12 passes through mounting blocks 100
Accurately load corresponding circumferential position in casing 13.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
