Unoccupied place assembles partition board 35 and compression mechanical part 3.
Fragmenting plate 42a and fragmenting plate 42b is made to misplace durings vibration that as a result, will not be when the operating of compressor 100 etc., it can
It prevents from generating big gap between each mating surface 43.
But, however it remains the gap caused by machining accuracy and the ladder generated by the machining accuracy of fragmenting plate.
Therefore, it is necessary in a manner that the respective mating surface 43 of fragmenting plate 42a, 42b are parallel with the direction of motion of two blades,
It is and sliding in the range (the blade sliding scale 49 in Fig. 3) on the edge of mating surface 43 with the first blade 10 and the second blade
Dynamic position relationship assembling partition board 35.
By assembling partition board 35 with the position relationship of such fragmenting plate 42a, 42b, from back pressure hole 11 to two blade fuel feeding
Refrigerator oil the mating surface of the side (0 ° of direction of crankangle) where two blades is fed into along with the movement of two blades
Between 43, oil seal can be formed between the mating surface 43 of fragmenting plate 42a, 42b, can form and not produced between by mating surface 43
The partition board of the influence of raw small ladder.
Next, the assemble method of the compressor using the description of the drawings present invention, especially fragmenting plate 42a and fragmenting plate
43 mutual fit system of each mating surface, charging method of the partition board 35 into compression mechanical part 3 of 42b.
Fig. 4 is compression mechanism assembling device 70 and is set to the schematic cross-section of this compression mechanical part 3.
Fig. 5 is the flow chart of the main points for the assembling sequence for representing compression mechanical part 3.
First, the first eccentric part 63a and second that the first roll sleeve 32a and the second roll sleeve 32b is inserted into bent axle 6 respectively is eccentric
The peripheral part of portion 63b measures the amplitude of oscillation of the first eccentric part 63a and the second eccentric part 63b when making the rotation of bent axle 6 respectively.
Eccentricity of each eccentric part relative to the axle center of bent axle 6 is obtained as a result,.(step 1)
Secondly, aligning is carried out based on the eccentricity being obtained before, so as to the first cylinder body 33a when compressor 100 operates
The peripheral surface of inner peripheral surface and the first roll sleeve 32a are mutually not excessively interfered, and the first framework 31a and the are fastened by short bolt 13
One cylinder body 33a.(step 2)
Similarly, second framework 31b and the second cylinder body 33b is fastened by short bolt 13.(step 3)
Then, 6 pre-inserted of bent axle is fastened to the first framework 31a and second framework of each cylinder body in step 2 and step 3
31b, checks whether axis smoothly rotates.(step 4)
Then, make 2 side of motor of bent axle 6 become downside, the location hole 33e opened up on the first cylinder body 33a is inserted into pressure
The compression mechanical part 3 of the positioning pin 71 of contracting mechanism assembling device 70, the thus state of fixing step 4.
Later, song is being clamped from the notch 45 for passing on left fragmenting plate 42a and from right side by the notch 45 of fragmenting plate 42b
In a state that 64 ground of middle part of axis 6 makes each cooperation of mating surface 43, fragmenting plate 42a and fragmenting plate 42b are preset in the first cylinder body
The centre of 33a and the second cylinder body 33b.
At this point, each mating surface 43 of fragmenting plate 42a and fragmenting plate 42b is in a manner of the nearby lateral inboard extension from Fig. 4
It is default.(partition board presets step)
Hereinafter, to it is parallel with the glide direction of each blade in the respective mating surface 43 that makes fragmenting plate 42a and 42b and with cunning
In a state that dynamic range overlaps, the sequence that partition board 35 is positioned and is fixed in compression mechanical part 3 illustrates.
Fig. 6 is the sectional view along the line A-A of Fig. 4.
In figure 6, X-axis is the imaginary Joinder references line for the mating surface 43 of fragmenting plate 42a, 42b to be aligned.
Origin is a bit on the central shaft of bent axle 6.
Y-axis is across origin and line orthogonal to X-axis.
Fragmenting plate 42a, 42b are predetermined in a manner that origin essentially becomes center and each mating surface 43 is aligned in X-axis.
Fragmenting plate support plate 72a stretches to the left and right of Fig. 6, and 2 front ends of V-shape are can to slide in defined position
The component of the peripheral surface of ground bearing fragmenting plate 42a.
Length between 2 front ends of fragmenting plate support plate 72a is bigger than the diameter of bent axle 6.

Pressing portion 73.
About fragmenting plate support plate 72b, diameter of the length also than bent axle 6 between 2 front ends is big, the front end of pressing portion 73
Diameter of the width also than bent axle 6 it is big.
The front end of fragmenting plate support plate 72a and fragmenting plate support plate 72b are in relative to the symmetrical position of Y-axis always.
In fragmenting plate support plate 72b, periphery that also can slidably with fragmenting plate 42b with the front end of V-shape opening
Face abuts, but simultaneously, the front end of pressing portion 73 contacts (mating surface positioning step) with the phase bit notch 48 of fragmenting plate 42b,
At this point, fragmenting plate 42b follows 73 ground of pressing portion to rotate to prescribed phases, moreover, fragmenting plate 42a follows the cooperation of fragmenting plate 42b
Face rotates to prescribed phases.
Each mating surface 43 of fragmenting plate 42a and fragmenting plate 42b overlaps in the state of the upper and lower directions towards Fig. 6 as a result,
And it is pushed.(step 5-1：Phase decision face pressing step)
In fact, according to the preset state of fragmenting plate 42a, 42b, the front ends of 2 positions of fragmenting plate support plate 72b with
And the sequence that pressing portion 73 is contacted with fragmenting plate 42b is different, but final, this peripheral surface of 3 positions all with fragmenting plate 42b connects
It touches.
Therefore, mating surface positioning step and phase decision face pressing step are carried out at the same time sometimes.
In addition, the length in the direction parallel with the mating surface 43 of fragmenting plate 42b of phase bit notch 48 is also set to than song
The diameter of axis 6 is big, therefore, as long as being pushed using the width pressing portion 73 bigger than the diameter of bent axle 6, fragmenting plate 42a just with
It is easily rotated with the mating surface of fragmenting plate 42b.
As described above, at this point, the first cylinder body 33a being integrally formed with the first framework 31a is positioned at compression by positioning pin 71
Mechanism assembling device 70.
In addition, due to being fixed in compression mechanism assembling device 70 from the upper and lower directions of Fig. 6 by air cylinder fixing mechanism 74, institute
With the center one of shaft through-hole 50 that can be with the center of the inner peripheral surface of the first cylinder body 33a and by the formation of axis notch 45
The mode of cause positions partition board 35 relative to the first cylinder body 33a.
