Description
Technical field
The utility model belongs to the motor device technical field, relates to a kind of electric machine casing, especially relates to a kind of electric machine casing that has at the bottom of the concave shell.
Background technology
The housing of motor is one of critical piece of motor, and the assembling and the operation of motor had important role.The housing of some micro-machines all is to adopt iron and steel to stretch to form at present, promptly at the bottom of forming cylindrical shell and shell after the stretching, just is integrally formed with cylindrical shell at the bottom of the shell like this.Above-mentioned employing stretches or the technology of cutting, and not only complex procedures, efficient are lower, and damages at the bottom of the shell because of external force makes easily, is difficult for carrying out the batch machining manufacturing, influence the quality of part, and the increase production cost simultaneously, is unfavorable for the assembling of motor.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example; The Chinese patent document discloses a kind of electric machine casing [application number: CN200820083429.1]; Electric machine casing is by two thin cylinder bodies that diameter is different; Through the assembly that its bottom couples together, integral body forms through cold extrusion with mould, and the relative position of two thin cylinder bodies can arbitrarily dispose.
Such scheme has improved prior art to a certain extent, makes that the production technology of electric machine casing is comparatively easy, and cost lowers to some extent.But this scheme adopts cold extrusion machine-shaping electric machine casing, and its processing technology is difficult to adapt to the needs of producing in batches; Simultaneously; Only rely on extrusion technique to be difficult to guarantee the quality of electric machine casing, the thin cylinder body damages easily, is unfavorable for the dismounting and the operation of motor in the electric machine casing simultaneously.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and a kind of reasonable in design, simple in structure, easy accessibility is provided, and is easy to processing and manufacturing, can improve the electric machine casing at the bottom of the concave shell that has of assembly precision.
For achieving the above object, the utility model has adopted following technical proposal: originally have the electric machine casing at the bottom of the concave shell, comprise the body of tubular; One end of body is uncovered; The other end has at the bottom of the shell, be connected as a single entity with body at the bottom of the described shell, at the bottom of the described shell through suppressing after at the annular groove of lateral surface formation sunk type; Medial surface forms the circular bulge loop corresponding with said annular groove at the bottom of shell, and the center of circle of described annular groove and circular bulge loop all is positioned on the center line of body.Promptly form inside and outside corresponding annular groove and circular bulge loop through simple pressing process at the bottom of the shell, circular bulge loop can make things convenient for the motor location, and annular groove can make things convenient between electric machine casing and the miscellaneous part and is connected, and press process is simple and easy to do.
In above-mentioned electric machine casing at the bottom of having the concave shell, have axially extended cell body on the described body, the opening of described cell body is positioned at the opening end of body.This structure can further strengthen the locating effect of motor.
In above-mentioned electric machine casing at the bottom of having the concave shell, the opening end of described body has some installation sheets that turn up, and described installation sheet is provided with through hole, and described installation sheet and body are connected as a single entity.Can electric machine casing be fixed on the desired position through installation sheet.
In above-mentioned electric machine casing at the bottom of having the concave shell, the opening end of described body is provided with some breach, is provided with some convex bodys in the described breach.
Compared with prior art; Originally the advantage that has the electric machine casing at the bottom of the concave shell is: reasonable in design, simple in structure, easy accessibility; Be easy to processing and manufacturing; Can improve assembly precision, circular bulge loop can strengthen the locating effect of motor, and annular groove and installation sheet can make electric machine casing be fixed on the desired position better.
