Another kind is on plastic packaging stator outer round surface, to stretch out several equally distributed boss, is provided with the stretch out face corresponding with plastic packaging stator boss on end cap, uses screw to carry out fastening through the boss of end cap and plastic packaging stator.This mode has following some unreasonable place: 1, use limitation larger, because fastening boss is distributed in plastic packaging stator cylindrical, the cylindrical of whole motor is increased, easy and motor load installation foot interferes, and causes not filling load; 2, positioning precision is not high, easily makes end cap be offset while playing screw, causes front and back end axiality bad, produces noise; 3, plastic packaging material and end cap shape become large, and material cost increases.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides the fixed structure of a kind of plastic packaging stator and end cap.
To achieve these goals, the utility model is by the following technical solutions: the fixed structure of a kind of plastic packaging stator and end cap, comprise plastic packaging stator, end cap and tapping screw, assembling place of described plastic packaging stator is formed with the first seam, described the first seam connecting end surface is provided with at least 2 boss, assembling place of described end cap is formed with the second seam, and described the second seam connects broken ends of fractured bone face and is provided with the recess matching with boss, and described plastic packaging electronics and end cap pass through self-drilling connection.
As preferably, in described boss, be embedded with inserts.
As preferably, described inserts be shaped as back taper.
As preferably, described inserts is established and is offered counterbore by plastic packaging stator connecting end surface place.
As preferably, described the first seam comprises the first male half coupling and the first inner stopper, described boss is located at the first male half coupling and the first inner stopper junction, and described the second seam comprises the second male half coupling and the second inner stopper, and described recess is located at the second male half coupling and the second inner stopper junction; Described the first male half coupling and the second male half coupling interference fits, described the first inner stopper and the second inner stopper interference fits.
As preferably, the connecting end surface place face of described recess is provided with circular hole.
As preferably, described inserts is made up of nylon or aluminum material.
As preferably, the quantity of described boss is 3.
The beneficial effects of the utility model are: the utility model end cap is pressed into plastic packaging stator, the first inner stopper interference fits of the second inner stopper of end cap and plastic packaging stator, the first male half coupling interference fits of the second male half coupling of end cap and plastic packaging stator, the recess of end cap the second inner stopper overlaps with the protuberance of plastic packaging stator the first inner stopper, it coordinates by end cap and plastic packaging stator internal and external stopper, has ensured the concentricity of rotor assembly and end cap; Play screw by the inserts in the first seam boss, ensure the coordinate intensity of end cap with plastic packaging stator, can not affect installing and using of client simultaneously, there is good use value and economic worth, be particularly useful for the motor of high-power large vibration, the inserts of back taper, has put and has prevented that inserts from departing from from plastics stator
The utility model is reasonable in design, simple in structure, has ensured positioning precision, has ensured again mechanical strength; Can not affect mechanical strength, good stability, long service life along with the variation of environment and temperature; Cost is relatively cheap, is applicable to applying.
