Abstract
The utility model provides a kind of rotor composite construction for connecting, for electric expansion valve, comprise rotor connecting plate (1) and stop rod link (2), stop rod (3) on stop rod link (2) inserts on rotor connecting plate (1) end face in corresponding through hole, and fastens and fit together with rotor connecting plate (1).A kind of rotor composite construction for connecting that the utility model provides can be realized stop and lower stop easily, as long as in the time of injecting magnetic rotor assembly, rotor composite construction for connecting is exchanged bottom surface.And can reduce the welding process of stop rod and rotor connecting plate, effectively improve manufacturing efficiency.This structure can reduce its production and process costs on the one hand, can ensure on the other hand the reliability of stop rod and magnet rotor.
Description
Technical field
The utility model relates to electronic expansion valve technology field, particularly a kind of magnet rotor linkage structure and stopper means.
Background technique
At refrigeration technology field, electric expansion valve is that one drives magnet rotor to rotate to change electronic expansion valve opening by coil magnetization, thus the throttling arrangement of adjusting refrigerant flow rate.Electric expansion valve is provided with stop component, and this stop component is a limit position part of electric expansion valve, and its Main Function is the opening degree of controlling electric expansion valve by the rotor stroke of restriction electric expansion valve.Rotor composite construction for connecting is the connection for transmission parts that connect magnet steel and needle, stop component.
How reducing the manufacture cost of rotor connection structure and stop component, ensure the reliability of stop rod simultaneously, is the problem that those skilled in the art need solution badly.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of rotor composite construction for connecting, for electric expansion valve, comprises rotor connecting plate and stop rod link, and rotor connecting plate and stop rod link are injection molded into integrative-structure by magnet steel after fastening assembling again.
Stop rod on described rotor composite construction for connecting can cylindrical shape magnet steel within, form lower stop rod form, also can be on cylindrical shape magnet steel, stop rod form in formation.
Described stop rod is that described stop rod link prolongation is directly bent to form.
Alternatively, on the end face of described rotor connecting plate and stop rod link, can be provided with through hole, the quantity of described through hole is 1-16, and the equivalent diameter in hole can be not identical.Lead to the hole site on described stop rod link end face can be corresponding with the through hole on described rotor connecting plate end face.
Alternatively, on described rotor composite construction for connecting annular end face, can only have central through bore.
On described rotor connecting plate, there is the through hole identical with stop rod section configuration, be convenient to stop rod and be inserted in.
Described rotor connecting plate periphery is provided with breach, and the corresponding periphery of stop rod link is provided with and the corresponding columnar projections of rotor connecting plate outer periphery notch.
The end face of described stop rod link can be circular, can be also polygonal.
The end face of described rotor connecting plate can be circular, can be also polygonal.
Described rotor connecting plate and stop rod link are sheet-metal formed part.
The rotor composite construction for connecting that the utility model provides injection moulding magnet steel easily, only needs to consider the form accuracy of injection mould, and needn't consider the precision of stop rod bending part mould; In addition, described rotor composite construction for connecting each several part is sheet-metal formed part, save turning processing, and owing to being formed by two fastenings, can reduce the thickness of panel beating, easier moulding, shaping die loss is little, and reduce the welding process of stop rod, and owing to having through hole on connecting plate end face, eliminated inside and outside differential pressure.Compared with prior art, can significantly cut down finished cost.
A kind of rotor composite construction for connecting that the utility model provides, can realize stop and lower stop easily, as long as in the time of injecting magnetic rotor assembly, rotor composite construction for connecting is exchanged bottom surface.And can reduce the welding process of stop rod and rotor connecting plate, effectively improve manufacturing efficiency.This structure can reduce its production and process costs on the one hand, can ensure on the other hand the reliability of stop rod and magnet rotor.
