Traditional method step is: car housing one end seam processed at first produces the seam end face; Be benchmark with the seam end face again, car housing endoporus; Be control vehicle housing other end seam with the housing endoporus then; At last stator module is compressed into endoporus.The major defect of this method is: because the location transformation of criterion, locate repeatedly, operational consistency is difficult for guaranteeing, produce error, make the relative two seam central axis of stator module axis produce circular runout, since disalignment, the structure matching reduction, magnetic field is asymmetric, the electric performance of motor is affected and the increase of motor operation noise.
Summary of the invention
The purpose of this utility model is to install the problem of easy off-centre at existing said stator, and the bloated device of tyre of a kind of motor field frame seam processing usefulness proposed, changed the motor processing sequence, serve as that the location benchmark is processed housing two ends seam simultaneously with the tire mandrel that expands, reach the coaxial of stator and two seams, improve machining accuracy, guarantee the electric performance of motor.
The purpose of this utility model can realize by following technical proposal:
A kind of bloated device of tyre of motor field frame seam processing usefulness, it comprises mandrel, tire core, rotation nut sleeve and the tubular expansion set of coaxial setting, the tire core is round table-like and is connected with mandrel, the rotation nut sleeve is connected with mandrel thread, expansion set is set on the tire core and an end is rotationally connected with the rotation nut sleeve, can also be provided with axial limiting mechanism between expansion set and the rotation nut sleeve, it is characterized in that, the side-wall shaft of described expansion set is to the dilatation seams that offers some end openings, and the inwall of expansion set and tire core outer surface are fitted.
In the bloated device of tyre of above-mentioned a kind of motor field frame seam processing usefulness, the opening of described dilatation seams is positioned at this side of big end of tire core.
In the bloated device of tyre of above-mentioned a kind of motor field frame seam processing usefulness, described dilatation seams has eight, evenly arranges at interval around the expansion set outer surface.
In the bloated device of tyre of above-mentioned a kind of motor field frame seam processing usefulness, offer some and above-mentioned dilatation seams stop hole one to one on the described expansion set, stop hole is communicated with the blind end of corresponding dilatation seams.This stop hole is appreciated that into and prevents that dilatation seams from tearing expansion set.
In the bloated device of tyre of above-mentioned a kind of motor field frame seam processing usefulness, described axial limiting mechanism comprises the annular boss that is arranged on the expansion set inwall and the annular slot that rotates the nut sleeve lateral surface, and boss is fastened in the draw-in groove.
Compared with prior art, this bloated device of tyre can be guaranteed the good axiality of housing inner stator internal diameter and two seams, and the assembling matching was good when housing was connected with end cap, and the magnetic field symmetry guarantees the motor electric property and reduces the motor rotation noise.
