The utility model purpose is to provide a kind of being convenient to that the stepping motor stator is ground endoporus processing, reduced the noise in the motor operation course, improved performance, the stepping motor stator mill internal clamp that has prolonged motor useful life, the tension and compression mode in the prior art of having solved has a rebound after processing the processing that the motor stator endoporus exists, still there be sweeping and do not have special fixture that motor stator is ground endoporus processing in boring situation or the prior art to a certain extent, use inconvenience, limited the problems such as raising in motor performance and life-span.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise base, described base is provided with the resilient sleeve that is hollow structure, the perisporium of resilient sleeve is provided with several breach, and inclined-plane outside outside the perisporium upper end of described resilient sleeve, being provided with, it is outer and be threaded with resilient sleeve that friction top is set in resilient sleeve, and described friction top upper end is inboard to be provided with the interior inclined-plane that cooperates with outer inclined-plane on the resilient sleeve.Wherein, the resilient sleeve perisporium is offered breach can make resilient sleeve radially possess elasticity, be convenient to the insertion of motor stator and the gathering of resilient sleeve motor stator is fixed, friction top is threaded with the resilient sleeve employing and the inclined-plane cooperates, and is convenient to the adjusting of the degree that compresses of resilient sleeve clamping motor stator.During use, screw off the friction top that is spirally connected with resilient sleeve, with motor stator is that workpiece is inserted in the resilient sleeve, then cover friction top, screw gland, cooperate with the outer inclined-plane in the outside, resilient sleeve upper end by inboard interior inclined-plane, friction top upper end and to make the resilient sleeve gathering, thereby motor stator is fastened in the resilient sleeve, by grinding machine the workpiece endoporus is processed, prevent the bounce-back after endoporus is processed, effectively avoided the boring of sweeping of assembling back rotor and stator, reduced noise, improve motor properties, prolonged the useful life of motor.
As preferably, described friction top lower end outer wall is provided with bulge loop, and described bulge loop is provided with some and groove friction top axis almost parallel.When rotating friction top, can hook groove on the friction top bulge loop, make things convenient for rotating operation by hook-headed wrench.
As preferably, described base is provided with some connecting bolts.This use is novel can be connected with grinding machine by connecting bolt, is fixed on the grinding machine motor stator is ground endoporus processing.
As preferably, described resilient sleeve is provided with annular inner convex platform down near the inboard, lower end, and the inner convex platform upper end is the plane under the described annular.Wherein, but annular is descended the end face holding workpieces lower surface of inner convex platform, is convenient to grind endoporus processing.
As preferably, inboard, described friction top upper end is provided with annular and goes up inner convex platform, described in the inclined-plane be located at inner convex platform inwall on this annular.Wherein, inner convex platform is set in quiet inboard on the friction top on the annular can makes and keep a determining deviation between friction top inwall and the resilient sleeve, make resilient sleeve possess bigger elasticity scope of activities, be convenient to clamping workpiece.
As preferably, described resilient sleeve perisporium is respectively equipped with annular groove near the outside in the described breach bottom, and it is bigger around property to make that the perisporium of resilient sleeve possesses, and is convenient to the gathering of perisporium and opens.
As preferably, described resilient sleeve bottom and base are provided with the through hole of mutual perforation, are convenient to the discharge to workpiece mill endoporus processing iron filings afterwards.
As preferably, described breach number is 2-4 and is evenly distributed on the resilient sleeve perisporium.
Therefore, the utlity model has and be convenient to the stepping motor stator is ground endoporus processing, reduced the noise in the motor operation course, improved performance, prolonged characteristics such as motor useful life.
