Background technology
Rotor assembly is the important component part on the automobile current generator, is that rotor is processed most important operation and press-fit operation, locatees inaccurately, causes the processing difficulties of subsequent handling, and severe patient often causes scrapping of workpiece.General technology is by forcing press at present, configures pressure assembling force, by seaming chuck the pawl utmost point is gone in axial compression, and the axle of tape spool shoulder directly is pressed onto the position, and the axle of tape spool shoulder is not by pressure head control compression distance.Pressure head need pass through certain heat treatment, increases hardness and intensity, in order to strengthen useful life.And general technology axle and the very difficult accurately location of pawl polar angle degree when press-fiting, make that operating efficiency and product quality are low.
The utility model content
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists, a kind of axle and the accurate orientation problem of pawl polar angle degree can solve high-power rotor press-mounting the time are provided, positioning accuracy when adding the trunk offering axle, reduce beating of axle when press-fiting, thereby increase work efficiency and product quality high-power generator rotor pressure head positioner.
The technical solution of the utility model: a kind of high-power generator rotor pressure head positioner, comprise the guiding pressure head, location pressure head and the positioning disk that cooperatively interact, described location pressure head is socketed on the axle, described positioning disk is arranged on pressure head below, location, described guiding pressure head is provided with the guide-localization sheet, gathering sill position with respect to axle on the pressure head of described location is provided with location hole, be provided with first positioning ball and first retainer spring that cooperatively interact in the described location hole, also be provided with the guide-localization groove that cooperates the guide-localization sheet on the pressure head of described location.
Preferably, described first positioning ball and first retainer spring are fixed in the location hole by first soket head cap screw, and described first positioning ball withstands the gathering sill of axle.
Preferably, described guide-localization sheet is fixed on the guiding pressure head by second soket head cap screw and second positioning ball that cooperatively interacts and second retainer spring.
Preferably, described positioning disk is provided with the alignment pin of the fixed claw utmost point.
Preferably, described first positioning ball is the steel ball of 2 Φ 8, and described second positioning ball is the steel ball of 2 Φ 4, and described first soket head cap screw is the M10 soket head cap screw, and described second soket head cap screw is the M5 soket head cap screw.
The utility model adopts the locate mode of spring and steel ball, realize convenient mounting and clamping, and employing gathering sill and guide-localization sheet, guarantee accurate positioning, thereby axle and the accurate orientation problem of pawl polar angle degree when having solved high-power rotor press-mounting, positioning accuracy when adding the trunk offering axle reduces beating of axle when press-fiting, and has improved operating efficiency and product quality.
