Abstract
The utility model discloses a kind of automobile-used excitation electromotor shell, adopt roll of steel plate around forming cylindrical shape, described cylinder passes through the combination button snapping be connected successively along seam length direction at seaming position place, each combination button is by main body button (1), the two oppositely buttons (2) being symmetricly set on main body button (1) left and right sides are formed, described two oppositely button (2) is made up of the first button block (2a) and the second button block (2b), and the first button block (2a) is detained block (2b) arrange in angle with second, described main body button (1) is contrary with two snapping direction of oppositely detaining (2), the middle part of described main body button (1) is provided with expansion salient point (3) and occurs gap in case clamping connects position.Manufacturing process is simple, low cost of manufacture, snapping firmly and there is no gap.
Description
Technical field
The utility model relates to automobile-used excitation electromotor technical field, is specifically related to a kind of shell mechanism for excitation electromotor.
Background technology
As shown in Figure 3; traditional automobile-used excitation electromotor shell adopts roll of steel plate around forming cylindrical shape; cylinder passes through the tack button snapping be connected successively along seam length direction at seaming position place; but owing to still there is gap after tack button snapping and snapping fastness is inadequate; so usually also need to toast again after snapping position is coated with adhering with epoxy resin, complex process and manufacturing cost is high.
Utility model content
The utility model improves for above-mentioned technical problem, intend providing that a kind of technique is simple, low cost of manufacture, snapping firmly and do not have apertured automobile-used excitation electromotor shell.
For this reason, the technical scheme that the utility model adopts is: a kind of automobile-used excitation electromotor shell, adopt roll of steel plate around forming cylindrical shape, key is: described cylinder passes through the combination button snapping be connected successively along seam length direction at seaming position place, each combination button is by main body button, be symmetricly set on the two of the main body button left and right sides and oppositely detain formation, described two oppositely button is made up of the first button block and the second button block, and the first button block and second to detain block be that angle is arranged, described main body button is contrary with two snapping direction of oppositely detaining, the middle part of main body button is provided with expansion salient point in case clamping connects position occur gap.
Be preferably, described main body cingulum has round end, and the width from round end to root successively decreases, and described expansion salient point is concentric with round end; Described two oppositely button is also with round end, but the width from round end to root remains unchanged; Further ensure the fastness of snapping.
The beneficial effects of the utility model:
(1) combination button snapping is adopted, this novel combination button is made up of main body button+bis-reverse button, and combination button is just in time contrary with two snapping direction of oppositely detaining, simultaneously twoly oppositely smash the first button block and second to detain block be that angle is arranged, ensure that the snapping fastness at seaming position place well, and improve snapping precision;
(2) on the basis of combination button, set up expansion salient point, during concrete assembling, first by combination button snapping, inevitably gap, snapping position, then riveting expansion salient point, make the metal of expansion salient point surrounding flow towards gap position place, thus gap is filled up, make snapping position not need bondingly just firmly to be connected.
In sum, the utility model simplifies manufacturing process, reduces manufacturing cost, ensure that snapping precision and fastness.
Accompanying drawing explanation
Fig. 1 is the structural representation after improving.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation before improving.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1, Fig. 2, a kind of automobile-used excitation electromotor shell, adopts roll of steel plate around forming cylindrical shape, and this cylinder is snapped together by three the combination buttons be connected successively along seam length direction at seaming position place.
Each button that combines is by main body button 1, two oppositely button 2 formations being symmetricly set on main body button 1 left and right sides.Two reverse button 2 is made up of the first button block 2a and second button block 2b, and the first button block 2a and second to detain block 2b be that angle is arranged, main body button 1 with two oppositely detain 2 snapping direction contrary, the middle part of main body button 1 is provided with expansion salient point 3 in case clamping connects position occur gap.
The broad outlines of the utility model design is: (1) two reverse button 2 is symmetricly set on the left and right sides of main body button 1; (2) the first button block 2a and second of two reverse button 2 detains block 2b is that angle is arranged; (3) main body button 1 with two oppositely detain 2 snapping direction contrary; (4) middle part of main body button 1 is provided with expansion salient point 3.
Preferably, main body button 1 is with round end, and the width from round end to root successively decreases, and expansion salient point 3 is concentric with round end; Two reverse button 2 is also with round end, but the width from round end to root remains unchanged.
Combination button is three, but is not limited to three, determines according to the length of shell.
Claims (3)
1. an automobile-used excitation electromotor shell, adopt roll of steel plate around forming cylindrical shape, it is characterized in that: described cylinder passes through the combination button snapping be connected successively along seam length direction at seaming position place, each combination button is by main body button (1), the two oppositely buttons (2) being symmetricly set on main body button (1) left and right sides are formed, described two oppositely button (2) is made up of the first button block (2a) and the second button block (2b), and the first button block (2a) is detained block (2b) arrange in angle with second, described main body button (1) is contrary with two snapping direction of oppositely detaining (2), the middle part of main body button (1) is provided with expansion salient point (3) and occurs gap in case clamping connects position.
2. according to automobile-used excitation electromotor shell according to claim 1, it is characterized in that: described main body button (1) is with round end, and the width from round end to root successively decreases, described expansion salient point (3) is concentric with round end; Described two oppositely button (2) is also with round end, but the width from round end to root remains unchanged.
