Abstract
The utility model discloses a coil structure of an expansion valve. The coil structure comprises a location clamp and a stator housing which is sleeved on a coil surface, wherein a plurality of location valve lugs are arranged on the annular location clamp, as an improvement, at least two riveting holes are formed in the corresponding parts of the stator housing and the location clamp, and rivets which are matched with the riveting holes are riveted with the stator housing with the location clamp. The riveting holes are formed in the corresponding parts of the stator housing and the location clamp, the stator housing and the location clamp are riveted with each other, so the coil structure has the beneficial effects that a novel physical punching or riveting technological method is adopted for substituting the original spot welding mode, the production cost is lowered, and the production efficiency and the percent of pass of products are improved.
Description
Technical field
The utility model relates to a kind of expansion valve loop construction.
Background technique
The expansion valve coil is everlasting and is installed a location card additional on the coil surface, connects and fixed valve body being used for.Location card often adopts the mode of spot welding to be fixed on the metal stator shell on surface of coil.And because of the coil metal shell often is coated with one deck electrodeposited coating because of antirust requirement, this electrodeposited coating can cause obstruction to spot welding, often causes rosin joint, comes off etc. badly, and the production scene is many smog and peculiar smell can occur; Simultaneously owing to adopt spot-welding technology to damage the shell electrodeposited coating, and the welding slag that produces during spot welding can affect to follow-up assembling, influences site environment and manufacturing efficiency.
Summary of the invention
The utility model provides a kind of simplification production technology for solving the problem that existing technology in use exists, and reduces technological requirement precision expansion valve loop construction simple in structure.
The technological scheme that the utility model solves existing issue is a kind of expansion valve loop construction; Comprise location card, be socketed on the stator casing of coil surface; The ring-type location card is provided with the lug of a plurality of positioning valves; As improvement, described stator casing and location card corresponding position are provided with at least two riveted holes, described rivet body riveted joint stator casing and the location card that cooperates with riveted holes.
As further improvement, described riveted holes is distributed on stator casing and the location card.
As further improvement, stator casing and the riveted holes on it are cold-punching molding.
The utility model compared with prior art; Through corresponding position on location card and the stator casing riveted holes is set; Connect stator casing and location card through riveted joint, its beneficial effect is to adopt the mode of the alternative original spot welding of technological method of novel physics punching press or riveted joint; Reduce cost of production, promoted manufacturing efficiency and product percent of pass.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the another kind of structural representation of this case study on implementation.
Fig. 3 is the utility model product assembling schematic representation.
Embodiment
Referring to Fig. 1-3; This case study on implementation comprises location card 1, is socketed on the stator casing 2 of coil surface; Ring-type location card 1 is provided with the lug 11 of a plurality of positioning valves; Stator casing 2 and location card 1 corresponding position are provided with at least two riveted holes, the rivet body 12 riveted joint stator casings 2 and location card 1 that cooperate with riveted holes.See Fig. 1, rivet body 12 can be to default in hollow circuit cylinder on the stator casing 2, with flange riveted way stationary positioned card 1; Seeing Fig. 2, also can be the rivet that defaults on the location card 1, connects stator casing 2 with the punching press riveted way.
Wherein riveted holes is distributed on stator casing 2 and the location card 1, and in order further to simplify process structure, stator casing 2 and the riveted holes on it are cold-punching molding.
