Abstract
The utility model relates to a riveting structure of motor shell and end cover and belongs to the technical field of motor production. The utility model comprises a shell and an end cover. The end of the shell is provided with a turn-up edge and at least two gaps. The turn-up edge is divided into a plurality of sections by the gaps. The end cover is provided with at least two protruding ears on the circumference, whose width is smaller than that of the gaps on the shell. The two sides of the gaps are provided with pressed pieces formed by the pressing of the shell, which cover the surface of the ears of the end cover. With low cost, simple working procedure, and high production efficiency, the utility model solves the problems that the connection of end cover and shell in the prior art is characterized by high producing cost, complicated working procedure, and low production efficiency.
Description
Technical field
The utility model relates to a kind of motor case and end cap riveted construction, belongs to the technical field that motor is produced.
Technical background
In the technical field that motor is produced, often adopt slotted collar to fix for going out hubcap with being connected of casing, the slotted collar that for this reason needs configure dedicated is with offer the groove of installing snap ring at casing inner wall, the above-mentioned mode that is connected and fixed that goes out hubcap and casing exists manufacturing cost higher, shortcomings such as operation is complicated, and production efficiency is lower.
Summary of the invention
The utility model purpose is to provide a kind of cost lower, operation is simple, and motor case that production efficiency is higher and end cap riveted construction have solved the end cap of prior art existence and the mode that is connected and fixed of casing and existed manufacturing cost higher, problems such as operation is complicated, and production efficiency is lower.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise casing and end cap, described casing end is provided with flange and at least 2 breach, described flange is divided into plurality of sections by breach, described end cap circumference is provided with the ear body of at least 2 evaginations, the width of described ear body is less than the width of the breach on the casing, described breach both sides are respectively equipped with the compressing tablet that is formed by the casing punching press, and described compressing tablet covers the ear body upper surface at end cap.The casing end is processed to form breach, to go out hubcap and be processed to form the ear body, during assembling, the ear body can place in the breach of casing end, during riveted the casing pendulum is made the U-shaped opening of breach corresponding to counterdie on counterdie, to go out hubcap again covers in the casing end and makes its ear body be positioned at the breach of casing, press drives counterdie, the edge of a knife of counterdie acts on casing breach both sides, make casing breach both sides be shoveled out a compressing tablet, this compressing tablet is on the hubcap ear body that baroclined under the effect of the edge of a knife, to go out the fixing purpose of hubcap and casing thereby play, and need not and be equipped with special-purpose snap ring at the casing inner wall fluting, its manufacturing cost is lower, operation is simpler, and production efficiency is higher.
As preferably, the number of described breach is 2-4, the number of described ear body be and the corresponding 2-4 of breach number individual.Wherein, the number of breach that cooperatively interacts and ear body can determine according to the size of motor case, when the casing diameter hour, can adopt the breach and the ear body of lesser amt, when the casing diameter is big, can suitably increase the quantity of breach and ear body.
As preferably, the outer end of described ear body and the excircle of flange are cut flat.Wherein, the excircle of the outer end of ear body and flange is cut flat, can be made after the assembling of this motor compact more succinct.
As preferably, described breach is evenly distributed on the casing end, thereby the flange on the end cap is separated into several sections uniformly, is that end cap and casing are fixing afterwards stressed more even.
Therefore, it is lower to the utlity model has cost, and operation is simple, and production efficiency is than characteristics such as height.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the local enlarged diagram in A place of Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, casing 1 end is provided with flange 2 and equally distributed 2 breach 3, the central angle of each breach 3 correspondence is 20 °, flange 2 is divided into uniform 2 sections by 2 breach, end cap 4 circumference are provided with the ear body 5 of 2 evaginations, the width of ear body 5 is less than the width of the breach on the casing 13, the central angle of ear body 5 correspondences is 18 °, the excircle of the outer end of ear body 5 and flange 2 is cut flat, breach 3 both sides are respectively equipped with the compressing tablet 6 that is formed by casing 1 punching press, and compressing tablet 6 covers the upper surface at the ear body 5 of end cap 4.
The casing end is processed to form breach, to go out hubcap and be processed to form the ear body, during assembling, the ear body can place in the breach of casing end, during riveted the casing pendulum is made the U-shaped opening of breach corresponding to counterdie on counterdie, to go out hubcap again covers in the casing end and makes its ear body be positioned at the breach of casing, press drives counterdie, the edge of a knife of counterdie acts on casing breach both sides, make casing breach both sides be shoveled out a compressing tablet, this compressing tablet will go out the fixing purpose of hubcap and casing thereby play on the hubcap ear body that baroclined under the effect of the edge of a knife.
Claims (5)
1, a kind of motor case and end cap riveted construction, comprise casing and end cap, it is characterized in that described casing end is provided with flange and at least 2 breach, described flange is divided into plurality of sections by breach, described end cap circumference is provided with the ear body of at least 2 evaginations, the width of described ear body is less than the width of the breach on the casing, and described breach both sides are respectively equipped with the compressing tablet that is formed by the casing punching press, and described compressing tablet covers the ear body upper surface at end cap.
