Referred to as feel relieved through hole, the first conjunction heart through hole, the second conjunction heart through hole, the 3rd conjunction heart through hole, the 4th conjunction heart through hole, the pentahapto heart are led to
Hole and six directions heart through hole are referred to as closing heart hole.Centering through hole and conjunction heart through hole are referred to as mounting hole.For close heart screwed hole,
First centering screwed hole, the number of the second centering screwed hole are designed according to being actually needed, correspondingly, other through holes of feeling relieved,
The number for closing heart through hole is designed according to heart screwed hole, the first centering screwed hole, the second number for feeling relieved screwed hole is closed, this hair
Bright embodiment two is not limited this.
Further, in the pump body structure for the rotary compressor that above-described embodiment two provides, three in first assembly
Close in heart through hole, the subtractive in aperture of the minimum conjunction heart through hole in aperture with closing heart screwed hole goes the first centering through hole and first to feel relieved
The difference that the difference in the aperture of screwed hole obtains is not less than 0.2mm and is not more than 1.0mm, specifically, 0.2mm≤| min (D21,
D25, D26)-M21}-(D11-M11)≤1.0mm.This way it is ensured that the centering of subassembly and subassembly and middle cylinder, second every
The conjunction heart of plate, first assembly is avoided because mounting hole dislocation can not assemble, is led so as to further reduce because mounting hole misplaces
The offline probability with pump housing refitting of the pump housing of cause, further increase the assembly qualified rate and efficiency of assembling of the pump housing.
Preferably, in the pump body structure for the rotary compressor that above-described embodiment two provides, three conjunction hearts in first assembly
In through hole, any two closes the absolute difference of heart through hole not less than 0 and is not more than 0.6mm.Specifically, | D21-D25|, | D21-
D25|, | D25-D26| ∈ X={ 0≤x≤0.6mm }.So, the conjunction heart assembling of first assembly has been effectively ensured, has further reduced
The pump housing is offline caused by mounting hole misplaces and the probability of pump housing refitting.
Preferably, 0.4mm≤| min (D21, D25, D26)-M21}-(D11-M11)≤1.0mm；
{|D21-D25|, | D21-D25|, | D25-D26| ∈ X={ 0≤x≤0.2mm }.
Certainly, in the case where technique allows, also can adjust above-mentioned numerical value is other values, it is not limited to above-mentioned implementation
Example.
In the embodiment of the present invention two, middle cylinder is closed into the heart on upper cylinder, certainly, also may be selected to exist in the middle cylinder conjunction heart
On lower cylinder.If middle cylinder is closed the heart on lower cylinder by selection, subassembly includes lower flange and lower cylinder, the first centering through hole
Lower flange is located at the first conjunction heart through hole, the first centering screwed hole and pentahapto heart through hole are located at lower cylinder, the second centering
Through hole and the 3rd conjunction heart through hole are located at upper flange, and the second centering screwed hole and the second conjunction heart through hole are located at upper cylinder.
Preferably, above-mentioned two embodiment provide rotary compressor pump body structure in, the second component and first every
Three on plate 3 are closed in heart through hole, and any two closes the aperture absolute difference of heart through hole not less than 0 and is not more than 0.6mm, has
Body, | D24-D22|, | D22-D23|, | D24-D23| ∈ X={ 0≤x≤0.6mm }.This way it is ensured that the second component and first
During dividing plate 3 and first assembly close the heart, the second component and the normal assembling of first partition 3, the second component and first are avoided
Dividing plate 3 is because mounting hole dislocation can not assemble, and so as to further reduce, the pump housing is offline and the pump housing caused by mounting hole misplaces
The probability of refitting, further increase the assembly qualified rate and efficiency of assembling of the pump housing.
Further, 0.4mm≤{ min (D22, D23, D24)-M21}-(D12-M12)≤1.0mm；
{|D24-D22|, | D22-D23|, | D24-D23∈ X={ 0≤x≤0.2mm }.
