Abstract
The utility model discloses a motor bearing chamber machining assembly which is an assembly for fashioning a motor end cover bearing chamber blank so as to produce an axle hole meeting the coaxial demand. The assembly is wholly arranged on a machine tool. The assembly comprises a grinding tool arranged on a machine tool spindle and an end cover positioning device which is superposed with an axis of the grinding tool and is oppositely arranged, wherein the end cover positioning device is provided with a cylindrical base having a core axle hole on the center thereof; the core axle hole is tightly matched with the motor end cover bearing chamber blank; the lower end of the base is a foundation; the upper end is a clamper superior part with the upper surface cycle thereof matched with the inner surface of the motor end cover; and the upper end face of the clamper superior part is provided with a positioning slot which is matched with a thread sleeve of the motor end cover. After the motor end cover bearing chamber blank is processed through the utility model, the shaft axis thereof is not away from the rotor and stator axis so the rotor can rotate smoothly and stably and the transmission power of the motor can be greatly improved.
Description
Technical field
The utility model relates to a kind of motor bearings chamber processing tool, a kind of specifically the fine finishining of electric motor end cap bearing chamber base substrate is met the frock that axiality requires to produce.
Background technology
In daily life or the manufacturing equipment in the sciemtifec and technical sphere and each quasi-instrument, the motor role is more and more important.Along with making rapid progress of science and technology, every data precision that people rotate motor requires also strict more, and the bearing chamber process technology of electric motor end cap is being played the part of an important ring, and it is the important leverage of the smooth and easy stable rotation of motor energy.In the existing process technology, generally be placed in the mould electric motor end cap and bearing chamber one-body molded, but Zhi Bei the axle sleeve axis hole uniformity, smoothness is relatively poor in this way, its axis easily is offset, can not effectively guarantee stator core and rotor shaft coaxial line, to reduce rotor and decided airgap uniformity degree like this, and cause motor when rotating, to be easy to generate vibration and significantly reduce transmission power.Therefore need again bearing chamber to be carried out fine finishining, meet the electric motor end cap bearing chamber that axiality requires to produce.
The utility model content
The utility model provides a kind of motor bearings chamber processing tool, and by the bearing chamber blank is finish-machined to satisfactory axis hole, the bearing chamber axis hole uniformity, the smoothness that have overcome traditional moulds production are relatively poor, and axial line departs from shortcomings such as rotor and axis stator.
The utility model adopts following technical scheme: a kind of motor bearings chamber processing tool, this frock integral installation is on lathe, described frock comprises the grinding knife tool that is installed on the machine tool chief axis, with this grinding knife tool dead in line and over against the end cap fixing device of placing, described end cap fixing device is the cylindric pedestal that the center has a mandrel hole, the bearing chamber blank of this mandrel hole and electric motor end cap closely cooperates, described pedestal lower surface is a base, its upper surface is all edges of upper surface and the suitable excellent portion of anchor clamps worker of electric motor end cap inner surface, and the upper surface of the excellent portion of these anchor clamps worker is provided with and the suitable retaining groove of electric motor end cap thread bush.
By above-mentioned description to the utility model structure as can be known, use the utility model that electric motor end cap bearing chamber blank is processed and have following advantage:
1, even through the bearing chamber axis hole aperture of frock processing, inner wall smooth.
2, the accurate axial line of location bearing chamber axis hole is guaranteed its non-migration rotor and axis stator, and is smooth and easy when making the rotor rotation, stable, significantly promotes the transmission power of motor.
Description of drawings
Fig. 1 is the user mode reference diagram of the utility model motor bearings chamber processing tool.
Fig. 2 is the vertical view of end cap fixing device of the present utility model.
Fig. 3 is the vertical half-sectional view of Fig. 2 along AA ' line.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to figure 1, Fig. 2, Fig. 3, the utility model is to be used for frock that the motor bearings chamber is processed, this frock integral installation is on lathe, grinding knife tool 2 is installed on the machine tool chief axis and (does not draw among the figure), in order to make it can produce axial rotation and to move radially, machine tool chief axis connects with oil cylinder by travelling gear and drive link.This frock also comprises an end cap fixing device, its lower end is cylindric pedestal 6, the lower surface of this cylindric pedestal 6 is a base 1, excellent 4 of the cylindric anchor clamps worker that the upper surface of end cap fixing device is formed in one, its external diameter makes excellent 4 outer rim of anchor clamps worker and suitable being advisable of electric motor end cap 3 inner surfaces particularly less than the external diameter of pedestal 6.Excellent 4 center of the anchor clamps worker of end cap fixing device has a mandrel hole 5, is used for fixing the bearing chamber blank 32 of end cap 3, and the size in mandrel hole 5 is can be advisable by nested bearing chamber blank 32 just.For the axial line that guarantees end cap bearing chamber 32 is not offset, make grinding knife tool 2 and end cap fixing device over against placement, allow the axial line in excellent 4 of anchor clamps worker, pedestal 6, mandrel hole 5 overlap with the axial line of grinding knife tool 2.Because electric motor end cap 3 inner surfaces are furnished with thread bush 31,33 usually, be used for cooperating stator core is fastened on the end cap, thereby be provided with retaining groove 41,42 in the upper surface of saddle, its position, aperture shape respectively with electric motor end cap on thread bush 31,33 suitable, can also add the steadiness that strengthens end cap man-hour to bearing chamber 32 like this.
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
