Abstract
The utility model discloses an expansion valve coil structure which comprises a locating clamp and a stator shell arranged on the surface of a coil. The ring-shaped locating clamp is provided with a plurality of lugs of locating valve bodies. As an improvement, at least three cuts are arranged on the edge of the ring-shaped locating clamp. Bending edges corresponding to the cuts protrude in the position corresponding to the stator shell. The bending edges are turned over and matched with the cuts to fasten the locating clamp. According to the expansion valve coil structure, the cuts are arranged on the locating clamp, the protruding bending edges are arranged in the position corresponding to the stator shell, and the bending edges is matched with the cuts to fasten the locating card. The expansion valve coil structure has the advantages that both the cuts and the bending edges can be formed at one shot through stamping technology, processing structure is simplified, machining efficiency of stamping forming is high, product uniformity is high, cost is lower, and massive manufacture is convenient.
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 the coil metal shell often is coated with one deck electrodeposited coating because of antirust requirement, and 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; The stator casing that comprises location card, coil surface; The ring-type location card is provided with the lug of a plurality of positioning valves, and as improvement, described ring-type location card edge is provided with at least three otch; Described stator casing corresponding position is protruding with the bending edges that adapts with otch, and described bending edges cooperates turnover fastening location card with otch.
As further improvement, at least three above-mentioned otch are distributed in the edge of ring-type location card; Above-mentioned bending edges thickness is 0.4-3mm.
As further improvement, described stator casing and the bending edges on it are impact briquetting, and work efficiency is high, good product consistency.
The utility model compared with prior art, through otch is set on the location card, the stator casing corresponding position is provided with the bending edges of protrusion; The bending edges fastening location card that matches with otch, its beneficial effect is that otch and bending edges all can be through the technology once-throughs of punching press; Simplify process structure, the impact briquetting work efficiency is high, and homogeneity of product is high; With low cost, be convenient to make in batches.

Embodiment
Referring to Fig. 1-3; This case study on implementation comprises the stator casing 2 of location card 1, coil surface; Ring-type location card 1 is provided with the lug 11 of a plurality of positioning valves, and ring-type location card 1 edge is provided with at least three otch 12, and stator casing 2 corresponding positions are protruding with the bending edges 3 that adapts with otch 12; When bending edges 3 cooperates turnover fastening location card 1 to prevent that location card 1 from coming off with otch 12, can prevent that again location card 1 and stator casing 2 from rotating relatively.
This case study on implementation is as optimization, and at least three otch 12 are distributed in the edge of ring-type location card 1; Bending edges 3 thickness are 0.4-3mm.
In order further to simplify process structure, stator casing 2 and the bending edges 3 on it are cold-stamped part.
