Embodiment
The present invention has utilized the swash plate of variable compressor to have these characteristics of variable-angle, by allowing after the swash plate inclination several angle piston and the crawler shoe cylinder block of once packing into.
As shown in Figure 7, at first cylinder block 1 is placed on the rotatable rotating disk 21, main shaft swash plate parts 1 are by a lifting and supporting mechanism (not shown), jacking a certain position to its mounting point, make and reserve certain space between swash plate 20 and the cylinder block 1, because the elastic force effect swash plate 20 of spring is in the position of almost horizontal.
As shown in Figure 8, along the swash plate deflection direction 20 groups of swash plates are changeed several angle then, the maximum space that produced by cylinder block jacking and swash plate deflection this moment be able to hold the installation of piston, by revolving cylinder body rotating disk, make a piston hole 11 of cylinder block 1 aim at this space biggest place, that is swash plate peak place.
As shown in Figure 9, then just piston 4 can be installed to the peak place of swash plate 20 together with crawler shoe 3.After this can loosen the commentaries on classics power of dialling to swash plate 20, because elastic force effect swash plate automatically replies original horizontal position, and owing to the piston hole 11 of piston 4 at this moment over against cylinder block 1, piston 4 can enter piston hole 11 very smoothly along with the answer of swash plate 20.Can certainly make swash plate keep deflection.
As shown in figure 10, revolving cylinder body rotating disk 21 makes the next piston hole of cylinder block 1 aim at swash plate deflection peak place, with identical method next piston is installed then; And in the revolving cylinder body, the piston that originally installed has also slipped in the piston hole simultaneously.Using such method just can be packed whole pistons in the cylinder block.

When being assembled to crawler shoe and piston on the swash plate, install for convenience, can adopt one " abaculus " in an alternative embodiment of the invention.Referring to Figure 12 and Fig. 9, Figure 12 shows the shape of this abaculus, the thickness of abaculus and the thickness of swash plate are roughly the same, so just can be with the position between pre-fixed crawler shoe 3 of this abaculus (as the label among Fig. 9 22) and the piston 4, so that leave the space suitable between two crawler shoes before crawler shoe and piston do not insert swash plate with swash plate thickness.Therefore, as long as crawler shoe 3 and abaculus 22 are come on the swash plate 20, utilize the hypotenuse of abaculus 22 to take out abaculus 22 then when installing on the swash plate 20 with piston 4 crawler shoe 3, only need touch piston 4 simultaneously, crawler shoe 3 just can be taken advantage of a situation to slide with piston 4 and be gone up swash plate 20.
In sum, piston once-through operation in assembling cylinder block of just can packing into, and can packing into by very smooth aligning piston hole has significantly reduced the part probability of damaging, and quality of product has obtained guarantee.And easy and simple to handle, labor intensity is low, and productive temp is short, satisfies and produces needs in enormous quantities.
Figure 13 illustrates according to the matching used equipment of the inventive method.As shown in the drawing, the power of the driving link of each actuating mechanism of this equipment provides by cylinder 41, equipment liquid passage inlet place device pneumatic triple piece 42.
Jacking supporting mechanism 43 and upper end guide sleeve 44 are realized the vertical lifting of main shaft swash plate parts.Lifting the link structure of stretching between cylinder and the push rod makes jacking can keep vertical, smooth and easy.
In the guide sleeve of upper end spring 45 is housed, waits assembling to utilize the restoring force of spring that main shaft swash plate parts are pushed back to its rigging position together with the piston that assembles after finishing.
Jacking supporting mechanism 43 can be adjusted with the relative axial position of upper end guide sleeve 44, and the compressor that so just can satisfy different cultivars assembles.
The rotating disk 47 of employing thrust ball bearing 46 can be steady, provides the cylinder block parts to carry out the circumference rotation uniformly; And is furnished with indexing locking mechanism 48.
Device structure among Figure 13 only plays illustration, does not make restriction, but structure the method according to this invention of assembly equipment is done many variations.
Though in the above-described embodiments, placing on the rotatable rotating disk with cylinder block is that example illustrates, can understand, and cylinder block is placed on the non-rotatable platform, by making the rotatable technological scheme of main shaft swash plate parts feasible too.Because connotation of the present invention is only required can relatively rotate between cylinder block and the main shaft swash plate parts and is got final product.For cylinder block fix and the embodiment of rotary main shaft inclined shaft except the rotatable portion difference, other step with above-mentioned with identical, so no longer be repeated in this description.
