Abstract
The utility model relates to a fastening structure of a motor end cover, comprising: a front end cover (1) and a back end cover (2). The combination part of the front end cover (1) and the back end cover (2) respectively bends outwards to form a turn-up edge (11) and a turn-up edge (21). The utility model is characterized in that a convex sleeve (3) is protruded from one turn-up edge (11), and a self-tapping bolt (4) is screwed into the sleeve (3) to press the turn-up edge (11) and the turn-up edge (21) together. The self-tapping bolt is screwed into the sleeve of one turn-up edge so as to press the two turn-up edges together, therefore, the utility model has the advantages of simple structure, few components, easy mounting, good fastening effect and uneasy falling-off.
Description
Technical field:
The utility model relates to a kind of electric motor end cap fastening structure.
Background technology:
The front end housing m1 of traditional drawing and forming and rear end cap m2 have bending to go out flange m11 and flange m21 respectively outward in the junction, two end cap relies on fastener that flange m11 and flange m21 installation are coupled together, as shown in Figure 1 and Figure 2, fastener comprises screw m3, bullet pad m4 and nut m5, this fastening means part is more, complicated operation when the production general assembly, neglected loading parts easily, perhaps bullet pad m5 is exploded and split, thereby lose the effect that prevents that nut m4 from getting loose in the overexertion of when locking.
The utility model content:
The purpose of this utility model provides a kind of electric motor end cap fastening structure, utilizes tapping screw to be screwed into the sleeve the inside of one of them flange, thereby two flange are pressed together, and simple in structure, number of parts is little, easy for installation, and is fastening effective, is difficult for getting loose.
The utility model is achieved by following technical proposals.
A kind of electric motor end cap fastening structure, comprise front end housing and rear end cap, the junction of front end housing and rear end cap all respectively bending outward go out flange and flange, flange is gone out the sleeve of projection therein, utilizes tapping screw to be screwed into the sleeve the inside two flange are pressed together.
Above-mentioned described front end housing and rear end cap are the stretching end caps, by the die drawn moulding.
The wall thickness of above-mentioned described stretching end cap is less than 10mm.
Above-mentioned described sleeve circumferentially is evenly distributed with a plurality of along flange.
The end face of above-mentioned described tapping screw is provided with tooth, and tooth bites into flange or flange the inside.
The length of above-mentioned described tapping screw is greater than the length of sleeve, and sleeve is stretched out in the bottom of tapping screw.
The length of above-mentioned described sleeve is greater than 1.5mm, guarantees fastening intensity.
The utility model compared with prior art has following advantage: 1) utilize tapping screw to be screwed into the sleeve the inside of one of them flange, at the inwall tap out of sleeve, thereby two flange are pressed together, simple in structure, number of parts is little, easy for installation, and is fastening effective, is difficult for getting loose; 2) end face of tapping screw is provided with tooth, and tooth bites into flange or flange the inside, can produce good self-locking action, prevents that the tapping screw rotation from getting loose; 3) length of sleeve is greater than 1.5mm, guarantees fastening intensity; 4) sleeve circumferentially is evenly distributed with a plurality ofly along flange, makes flange stressed more even.
