Main purpose of the present invention is at the problems referred to above, a kind of processing of motor field frame seam expand tire and application process thereof are provided, changing on the existing technological operation order basis, with the tire mandrel that expands serves as that the location benchmark is processed housing two ends seam simultaneously, reach the coaxial of stator and two seams, and obtain to improve machining accuracy, guarantee the effect of the electric performance of motor, reduction noise and simplification procedure of processing.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of motor field frame seam processing tire that expands, it is characterized in that by the mandrel of coaxial setting, expansion set, nut sleeve and fasteningly constitute with O type circle, described mandrel comprise both sides end axle, middle part truncated cone expansion set core and be connected in threaded shaft section four parts on expansion set core frustum of a cone top, described expansion set is the cylindrical jacket that is made of the bloated piece amalgamation that separates vertically more than three, expansion set is sleeved on the expansion set core outside with its inboard truncated cone cavity that coincide with truncated cone expansion set core, and holds together to be integral body by O type circle hoop; Described nut sleeve is sleeved on described threaded shaft section outside to be threaded, expansion set reaches outer groove with the mutual setting-in connection of matched in clearance by all inner groovies of the ring of its inboard, end setting and inner convex platform with the ring week outer lug boss of the nut sleeve end corresponding setting in the outside.
Described expansion set is made of three identical bloated pieces.
A kind of above-mentioned motor field frame seam processing application process of the tire that expands is characterized in that comprising the steps:
(1) processing motor field frame endoporus;
(2) stator module is pressed in the motor field frame endoporus;
(3) the tire swelling pressure that will expand is gone in the endoporus of stator module: the tire that will expand inserts in the stator module endoporus, manually rotates nut sleeve, and the frustum of a cone bottom of expansion set core is moved in expansion set and the roof pressure piece that expands, and make the piece that expands separated from one another, and then the expansion set roof pressure is on stator inner wall;
(4) be a core positioning motor housing with the tire mandrel that expands,, process the seam of motor field frame both sides simultaneously with the parallel two lathe tools that are provided with.
The invention has the beneficial effects as follows: adopt bloated tire processing motor field frame seam provided by the invention and application process thereof, improved existing technological operation order, at first process the housing endoporus and be pressed into stator module, and be benchmark with the mandrel that swelling is pressed into the bloated tire in the stator module, process the seam of housing both sides simultaneously, the precise measure of tire and the good axiality that accurate location guarantees housing inner stator internal diameter and two seams expand, the assembling matching was good when housing was connected with end cap, the magnetic field symmetry, not only guarantee the electric property of motor and reduce the motor operation noise, especially be reduced to by original twice independent processing seam and finish seam processing simultaneously, processing step is simplified, cut down finished cost.
