Hereinafter, to dividing plate 35 and the structure of fragmenting plate 42a, 42b of constituting dividing plate 35, accompanying drawing is used to illustrate.
Fig. 3 is the top view of the dividing plate 35 being made up of 2 fragmenting plates 42a, 42b.
43 sides have the axle otch 45 of semicircle shape in cooperation face for fragmenting plate 42a, 42b, and fragmenting plate 42a, 42b are with from both sides
The mode of the pars intermedia 64 that the part utilizing axle otch 45 clamps bent axle 6 is assembled and forms dividing plate 35.
At the two ends coordinating face 43 of fragmenting plate 42a, 42b, there is the projection for fragmenting plate 42a, 42b being interfixed
Portion 47, has hole 44a, 44b of fastening on this jut 47.
Hole 44a, 44b are connected and utilizes the bolt and nut 46 etc. of fastening to fasten fragmenting plate 42a, 42b.
Thus, even if the diameter of the shaft through-hole 50 formed by 2 relative axle otch 45 is than the first eccentric part of bent axle 6
The diameter of 63a or the second eccentric part 63b is little, it is also possible to assemble compressible mechanism part 3.
It addition, the phase bit otch 48 (phase decision used when assembling dividing plate 35 on the outer peripheral face of fragmenting plate 42b
Face) it is plane, arrange abreast with coordinating face 43.
The length of the circumference parallel with cooperation face 43 of phase bit otch 48 is set to bigger than the diameter of bent axle 6.
Details about its reason and the using method of phase bit otch 48 is explained below.
As it has been described above, on fragmenting plate 42a, 42b, the jut 47 at the both ends in cooperation face 43 is provided with bolt solid
The tabular surface determined and hole 44a, 44b, become by fixing fragmenting plate 42a, 42b structures each other such as bolts.
Make fragmenting plate 42a, 42b merga pass bolt and nut 46 etc. that matches be fixed, it is possible to not have big between
Unoccupied place assembles dividing plate 35 and compression mechanical part 3.
Thus, fragmenting plate 42a and fragmenting plate 42b dislocation will not be made because of the vibration during operating of compressor 100 etc., it is possible to
Prevent from producing big gap between each cooperation face 43.
But, however it remains the gap caused because of machining accuracy and the ladder produced by the machining accuracy of fragmenting plate.
Accordingly, it would be desirable in the way of the respective cooperation face 43 of fragmenting plate 42a, 42b is parallel with the direction of motion of two blades,
And it is sliding in the scope (the blade sliding scale 49 in Fig. 3) on the edge coordinating face 43 with the first blade 10 and the second blade
Dynamic position relationship assembles dividing plate 35.
Dividing plate 35 is assembled, from back pressure hole 11 to two blade fuel feeding by the position relationship with such fragmenting plate 42a, 42b
Refrigerator oil be fed into the cooperation face of the side (0 ° of direction of crankangle) at two blade places along with the motion of two blades
Between 43, oil seal can be formed between the cooperation face 43 of fragmenting plate 42a, 42b, it is possible to constitute and do not produced by between cooperation face 43
The dividing plate of the impact of raw small ladder.
It follows that use the assemble method of the compressor of the accompanying drawing explanation present invention, especially fragmenting plate 42a and fragmenting plate
42b each coordinates face 43 fit system each other, the dividing plate 35 charging method in compression mechanical part 3.
Fig. 4 is the schematic cross-section of compression mechanism assembling device 70 and the compression mechanical part 3 being arranged at this.
Fig. 5 is the flow chart of the main points of the assembling sequence 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 inserts bent axle 6 respectively is eccentric
The peripheral part of portion 63b, measures the first eccentric part 63a when making bent axle 6 rotate and the amplitude of oscillation of the second eccentric part 63b respectively.
Thus, each eccentric part offset relative to the axle center of bent axle 6 is obtained.(step 1)
Secondly, aligning is carried out based on the offset obtained before, in order to the first cylinder body 33a when compressor 100 operates
The outer peripheral face of inner peripheral surface and the first roll sleeve 32a is the most not excessively interfered, and fastens the first framework 31a and by short bolt 13
One cylinder body 33a.(step 2)
Similarly, the second framework 31b and the second cylinder body 33b are fastened by short bolt 13.(step 3)
Then, bent axle 6 pre-inserted is fastened in step 2 and step 3 first framework 31a and second framework of each cylinder body
31b, checks that axle the most smoothly rotates.(step 4)
Then, make motor 2 side of bent axle 6 become downside, hole, the location 33e offered on the first cylinder body 33a is inserted into pressure
The alignment pin 71 of contracting mechanism assembling device 70, the thus compression mechanical part 3 of the state of fixing step 4.
Afterwards, from passing on left the otch 45 of fragmenting plate 42a and clamping song from right side by the otch 45 of fragmenting plate 42b
Pars intermedia 64 ground of axle 6 makes, under the state that each cooperation face 43 coordinates, fragmenting plate 42a and fragmenting plate 42b to be preset in the first cylinder body
33a and the centre of the second cylinder body 33b.
Now, each of fragmenting plate 42a and fragmenting plate 42b coordinates face 43 by the way of the nearby lateral inboard extension of Fig. 4
Preset.(step preset by dividing plate)
Hereinafter, to parallel with the glide direction of each blade in the respective cooperation face 43 making fragmenting plate 42a with 42b and with cunning
Under the state that dynamic scope overlaps, the order that dividing plate 35 is positioned and is fixed in compression mechanical part 3 illustrates.
Fig. 6 is the sectional view of the line A-A along Fig. 4.
In figure 6, X-axis is the imaginary Joinder references line for being aligned in the cooperation face 43 of fragmenting plate 42a, 42b.
Initial point is a bit on the central shaft of bent axle 6.
Y-axis is through initial point line orthogonal to X-axis.
Fragmenting plate 42a, 42b essentially become in the way of aliging in X-axis in center and each cooperation face 43 by initial point and are predetermined.
Fragmenting plate support plate 72a is flexible to the left and right of Fig. 6, and 2 leading sections of V-shape are can to slide in the position of regulation
The parts of the outer peripheral face of ground supporting fragmenting plate 42a.
Length between 2 leading sections of fragmenting plate support plate 72a is bigger than the diameter of bent axle 6.
Fragmenting plate support plate 72b is provided integrally with the front end with V-shape opening and smooth between the leading section of this V-shape
Pressing portion 73.
About fragmenting plate support plate 72b, the length between 2 leading sections is also big than the diameter of bent axle 6, the front end of pressing portion 73
Width also big than the diameter of bent axle 6.
The leading section of fragmenting plate support plate 72a and fragmenting plate support plate 72b is in the position symmetrical relative to Y-axis all the time.
In fragmenting plate support plate 72b, with the leading section of V-shape opening also be able to slidably with the periphery of fragmenting plate 42b
Face abuts, but simultaneously, the front end of pressing portion 73 contacts (coordinating face positioning step) with the phase bit otch 48 of fragmenting plate 42b,
Now, fragmenting plate 42b follows pressing portion 73 ground and rotates to prescribed phases, and, fragmenting plate 42a follows the cooperation of fragmenting plate 42b
Face rotates to prescribed phases.
Thus, fragmenting plate 42a and fragmenting plate 42b each coordinates face 43 to overlap when towards the above-below direction of Fig. 6
And be pushed.(step 5-1: phase decision face pressing step)
It practice, according to the preset state of fragmenting plate 42a, 42b, the leading section of 2 positions of fragmenting plate support plate 72b with
And pressing portion 73 is different with the order that fragmenting plate 42b contacts, but finally, these 3 positions all outer peripheral faces with fragmenting plate 42b connect
Touch.
Therefore, coordinate face positioning step and phase decision face pressing step to carry out the most simultaneously.
Additionally, the length in the direction parallel with the cooperation face 43 of fragmenting plate 42b of phase bit otch 48 is also set to than song
The diameter of axle 6 is big, therefore, as long as the pressing portion 73 utilizing width bigger than the diameter of bent axle 6 pushes, fragmenting plate 42a just with
Change places rotation with the cooperation face of fragmenting plate 42b.
As it has been described above, now, the first cylinder body 33a being integrally forming with the first framework 31a is positioned pin 71 and is positioned compression
Mechanism's assembling device 70.
Further, since be fixed on compression mechanism assembling device 70 from the above-below direction of Fig. 6 by air cylinder fixing mechanism 74, institute
With, it is possible to the center of the inner peripheral surface of the first cylinder body 33a and the center one of shaft through-hole 50 that formed with otch 45 by axle
The mode caused, positions dividing plate 35 relative to the first cylinder body 33a.
