Abstract
The utility model discloses a kind of brushless electric machine front and rear cover fastening structure, comprise: body, be located at front end housing on body and rear end cap and be located at the securing member of front end housing and rear end cap, securing member comprises the front fixed block being fixed at front end housing periphery and the rear fixed block being fixed at rear end cap periphery, be interspersed with fastening cramp between described front fixed block and rear fixed block, described cramp one end is deformability fastening end.By the way, the utility model in guarantee brshless DC motor normal function situation, can utilize rational structure, reduce overall dimension and the volume of motor, reduce weight and the cost of motor, the function of equal brushless electric machine can be reached, and concise in technology.
Description
Technical field
The utility model relates to brushless electric machine field, particularly relates to a kind of small size class brushless electric tool class motor front and rear cover fastening structure.
Background technology
This brushless electric machine many employings screw connects front and rear cover at present, thus reaches the fastening effect of motor front and rear cover.
But this fastening structure cannot reduce motor overall dimension and volume, more cannot reduce motor weight, occupy complete machine on the contrary and more space is provided, and screw technique for fixing be loaded down with trivial details, expends time in.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of reduction motor overall dimension and volume, reduces motor weight, for complete machine provides more space, and manufacture craft simple brushless electric machine front and rear cover fastening structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of brushless electric machine front and rear cover fastening structure, comprise: body, be located at front end housing on body and rear end cap and be located at the securing member of front end housing and rear end cap, securing member comprises the front fixed block being fixed at front end housing periphery and the rear fixed block being fixed at rear end cap periphery, be interspersed with fastening cramp between described front fixed block and rear fixed block, described cramp one end is deformability fastening end.
In the utility model preferred embodiment, front end housing periphery and rear end cap periphery are at least provided with four groups of front fixed blocks and rear fixed block, are all interspersed with cramp between each group fixed block.
In the utility model preferred embodiment, described cramp is the shaping strip of plate stamping.
In the utility model preferred embodiment, described cramp is punctured into rear fixed block by front fixed block, and the cramp end exceeding rear fixed block is deformability fastening end.
In the utility model preferred embodiment, described cramp is punctured into front fixed block by rear fixed block, and the cramp end exceeding front fixed block is deformability fastening end.
The beneficial effects of the utility model are: the utility model brushless electric machine front and rear cover fastening structure is in guarantee brshless DC motor normal function situation, utilize rational structure, reduce overall dimension and the volume of motor, reduce weight and the cost of motor, the function of equal brushless electric machine can be reached, and concise in technology.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model brushless electric machine front and rear cover fastening structure one preferred embodiment;
Fig. 2 be the front and rear cover of brushless electric machine shown in Fig. 1 fastening structure unassembled time stereogram;
In accompanying drawing, the mark of each parts is as follows: 1. rear end cap, 2. cramp, 3. front end housing.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of brushless electric machine front and rear cover fastening structure, comprising: body, is located at front end housing 3 on body and rear end cap 1 and is located at the securing member of front end housing 3 and rear end cap 1.Replace screw to fix with securing member, compact conformation, overall dimension is little, and volume is little, weight reduces.
Securing member comprises the front fixed block being fixed at front end housing 3 periphery and the rear fixed block being fixed at rear end cap 1 periphery, is interspersed with fastening cramp 2 between described front fixed block and rear fixed block,
The utility model preferred embodiment is: front end housing 3 periphery and rear end cap 1 periphery are at least provided with four groups of front fixed blocks and rear fixed block, is all interspersed with cramp 2 between each group fixed block.
Described cramp 2 is the shaping strip of plate stamping.Described cramp 2 one end is deformability fastening end.
Fixed block after described cramp 2 is punctured into by front fixed block, the cramp end exceeding rear fixed block is deformability fastening end.Fastening effect is reached after being out of shape by straight line by deformability fastening end.
When described cramp 2 by after fixed block be punctured into front fixed block, the cramp end exceeding front fixed block is deformability fastening end.Fastening effect is reached after being out of shape by straight line by deformability fastening end.
The utility model brushless electric machine front and rear cover fastening structure is in guarantee brshless DC motor normal function situation, utilize rational structure, reduce overall dimension and the volume of motor, reduce weight and the cost of motor, the function of equal brushless electric machine can be reached, and concise in technology.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
