Description
technical field
The present invention relates to the technical field of Miniature refrigerating device assembly tool, specifically a kind of technology that is exclusively used in the assembly apparatus of minisize refrigeration compressor and the assembly method of compressor.
background technique
Along with socioeconomic development and technological progress, people's living standard improves, and the application demand of various portable Miniature refrigerating devices is more and more extensive.In various minitype portable refrigeration plants, vapour compression refrigeration because of its refrigeration (heat) efficiency height be still best selection, and as vapor compression refrigeration system core component---the research and development of micro-compressor just become its key technology.Being suitable for minisize refrigeration compressor that portable refrigerating device uses wants cube little lightweight and efficiency is high, in various refrigeration compressor patterns, rolling rotor-type is called again the compressor of rolling-piston-type, rotary-piston type because of its simple structure, various manufacturing process technologies are ripe, become the first-selection that the most easily realizes commercial micro-compressor.
Existing cooling full-sealed rolling rotator compressor is mainly used in domestic air conditioning, dehumidifier, drinking machine etc., minimum refrigerating capacity (air conditioning condition) more than 500W, delivery space is greater than 3.0cm3/rev, and profile trunk diameter is more than 80mm, and weight surpasses 3kg.And the general refrigerating capacity of the compressor that is applicable to Portable movable refrigeration plant requires below 500W (air conditioning condition), delivery space is less than 3.0cm3/rev, and profile trunk diameter is below 55mm, and weight is no more than 1kg.As portable mobile refrigeration plant, most use occasions need portable portable cell to power as power supply, thereby the high efficiency of micro-compressor (and refrigerating efficiency or Energy Efficiency Ratio COP) is very crucial.
The working principle of rolling piston compressor pressurized gas is: the flange at cylinder and its two ends, be called master, supplementary bearing, form an airtight space, eccentric setting piston in it, piston and cylinder bore diameter form a crescent-shaped space, cylinder wall one side has a straight trough, inside take in a slide plate, one end of slide plate is pressed on the outer circumferential face of piston, so above-mentioned crescent-shaped space has been divided into two-part, piston rolls along cylinder bore diameter under eccentric crankshaft rotarilys actuate, slide plate is reciprocating in vane slot, above-mentioned crescent-shaped space just moves in cylinder, at this moment the space of slide plate one side can dwindle gradually, compressed and the pressure of airtight gas within it raises, finally by the venting gas appliance arranging, be discharged to compressor pump external, the space of opposite side expands gradually and sucks gas simultaneously, is rotated further, and this space gas is compressed again.Along with the continuous rotation of driven by motor bent axle, the compression pump housing even continuous reciprocally complete air-breathing → compression → exhaust → air-breathing, is realized lifting and the conveying of refrigerant gas pressure.
As above described in working principle, during rolling rotor type compressor work, between each moving element, all there is gap, as between cylinder bore diameter and piston external diameter, between pistons end and major-minor bearing, between slide plate side and cylinder vane slot, between slide plate head and piston outer circumferential face etc., these gaps also may form the internal leakage passage of pressurized gas, internal gas leakage can cause the reduction of compressor air-discharging amount, and compression efficiency and refrigerating capacity decline.Oiling refrigerator oil in the shell space of compression pump housing bottom, its effect one is lubricated to each moving element, its two be exactly to each clearance portion by setting up oil film seal, it three is heats that produce with pressurized gas of taking away that each Machinery Ministry motion produces.That is to say, the gap in the compression pump housing between each moving element is by oil film seal, and the foundation of oil film needs suitable matching gap to guarantee, excesssive gap or too smallly all can not set up effective oil film.
For micro-compressor, because its air displacement is little, the gas leakage amount in its compression pump housing between various gaps just seems very obvious to the impact of its refrigerating capacity.So for to guarantee that micro-compressor has higher refrigerating capacity and Energy Efficiency Ratio (COP), the Spielpassung design between each moving element is particularly important, and the accuracy of manufacturing of component and assembly precision are had higher requirement.
Meanwhile, guarantee that the efficiently the most direct means of micro-compressor adopt high efficiency motor exactly, the general employing of micro-compressor can directly be used the brushless direct-current synchronous machine (BLCD) of DC power supply efficiently; Also need on the other hand to improve the Design and manufacture assembling level of motor, further to improve raising electric efficiency.In affecting the manufacture process of electric efficiency, motor stator and rotor gap control during assembling is the problem that is difficult to resolve always.For micro-compressor, for guaranteeing the high efficiency of motor, the requirement that its motor stator and rotor gap is generally designed to the existing compressor this gap of monolateral gap 0.2～0.3mm(is O.5～0.6mm) and require circular gap even, thereby this problem just seems particularly outstanding.
The typical structure of full-sealed rolling rotator refrigeration compressor as vertical rolling rotor type compressor, in the housing of full closed, fixedly pack the pump housing part of pressurized gas and the motor part of drive compression pump housing rotary work into, conventionally compressor pump body is fixed by three spot welding or multi-point welding and housing parts, motor part is that motor stator and housing are fixed by interference fit hot jacket mode, also has by the mode of multiple-spot welding and fixes.The rotor of motor is received in motor stator internal diameter, is connected with the bent axle stretching out in the compression pump housing, by electrical power rotor band dynamic crankshaft, is rotated and is realized pressurized gas.In existing rolling piston compressor assembly process, the hot jacket of the welding of compressor pump body and housing and motor stator and housing is fixedly taken up in order of priority and is carried out, and has plenty of the existing spot welding that stator and housing hot jacket are carried out to the pump housing after good again and fixes; Have plenty of the housing that a little welds pump housing portion with stator heating jacket.Which kind of scheme no matter, all needs repeating and clamping location repeatedly, certainly will exert an influence to the required precision of each parts fit up gap.
