Abstract
The utility model relates to a magnetic rotor integrated structure, comprises an alnico and a lead screw, the alnico is made of the mixture of the macromolecule binding material and the magnetic material which are through injection molding craft and made as a whole with the lead screw, a rib ring is arranged in the connective place of the alnico and the lead screw in the lead screw, thereby making the utility model be characterized in simple processing technology, both can ensure the alnico and the lead screw in the same shaft angle, and increase the anti vibration and the coolants resistant of the rotor at the same time, and can reduce the number of the components and parts, lower the cost, decrease the moment of inertia and increase the rotation capability of the rotor, etc.
Description
Technical field
The utility model relates to rotor or valve core structure in a kind of electric expansion valve or the similar valve body, belong to the parts of valve.
Background technique
The magnet steel that the structural type of existing electric expansion valve rotor part mainly includes screw mandrel and is attached thereto, magnet steel is fixed on the periphery of screw mandrel, this structural type can not guarantee the coaxality of magnet steel and screw mandrel, vibration resistance is poor, and because of having increased extra union piece, thereby cause the rotary inertia of rotor to strengthen, reduced the rotating property of rotor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of magnet rotor integrated formed structure that magnet steel and screw mandrel are made of one piece, it includes magnet steel and screw mandrel, and magnet steel is that the mixture of polymeric adhesive and magnetic material is made one by injection molding process and screw mandrel.
Described screw mandrel is provided with a muscle circle, and contain and above-mentioned muscle circle the one-body molded joint of magnet steel and screw mandrel.
Described magnet steel is a plastic-steel compound body, and its internal layer has the interior cover of plastics one-body molded with screw mandrel, and skin has magnet steel to be shaped on the outer wall of cover in the plastics.
The utility model is owing to methods such as employing molding and forming, and technology is simple, can guarantee the coaxality of screw mandrel and magnet steel, can improve simultaneously the anti-vibration and the cold-resistant matchmaker distortion of rotor again, and can also reduce number of components and parts, reduce cost, reduce rotary inertia, improved the rotating property of rotor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another example structure schematic representation of the present utility model.
Fig. 3 is another example structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly includes magnet steel 1 and screw mandrel 2, the body of rod of screw mandrel 2 is provided with a muscle circle 3, the mixture that adopts high polymer binder and magnetic material outside the screw mandrel 2 of this muscle circle 3 is made the magnet steel 1 of one by injection molding process and screw mandrel, and described muscle has enclosed strengthens fixedly connected effect.Because magnet steel 1 is to be made of one piece with screw mandrel 2, thereby can guarantee the coaxality of screw mandrel and magnet steel 1, guarantee both adhesive strengths, improved the anti-vibration of whole rotor and cold-resistant matchmaker and be out of shape etc.Shown in Figure 2, present embodiment is one-body molded and be fixed together at the middle part of magnet steel 1 and screw mandrel 2.Shown in Figure 3 is to have increased a plastic part between magnet steel 1 and screw mandrel 2, regard plastic part and magnet steel as a plastic-steel compound body, its internal layer has the interior cover 4 of plastics one-body molded with screw mandrel 2, skin has magnet steel 1 to be shaped on the outer wall of cover 4 in the plastics, its objective is to save expensive magnetic material in some large-scale electric expansion valves.
