Abstract
A screw-fixed polar positioning tool for a mandrel of a pole core relates to a motor pole core, and comprises a positioning screw bolt, a positioning sleeve and a pin. The utility model solves the technical problem that the screw-fixed polar positioning tool for the mandrel of the pole core provided by the utility model can maintain the consistent position of a screw hole on the mandrel and a square screw bolt slot of a polar punching sheet of the pole core, and maintain the perpendicularity between a center line of the screw hole of the mandrel and an axial line of the pole core during piling up the pole core. The outer side surface of the positioning sleeve is matched with the square screw bolt slot of the polar punching sheet, the middle part of the positioning screw bolt is matched with a circular hole in the middle of the positioning sleeve, and the lower end of the positioning screw bolt is in threaded connection with the mandrel of the pole core, thereby better solving the technical problem during piling up the pole core and improving efficiency. The utility model can be applied to the screw-fixed polar positioning of the mandrel during piling up the pole core.
Description
Technical field
The utility model relates to the motor pole iron core, particularly the pole core axle orientation tool of screw rod fixed magnetic pole.
Background technology
Usually the slowspeed machine magnetic pole adopts screw rod and yoke to fix, for improving the constant intensity of magnetic pole, in pole core, be installed with axle, be drilled with the fixing screw of using of magnetic pole on the axle in advance, go out the breach of respective width earlier at the pole lamination of axle screw relevant position, screwhole position forms square opening during the pole core closed assembly, i.e. the square screw slot of pole lamination, and square screw slot is corresponding with the screw on the magnetic pole axle; Screw and the square screw slot position consistency of pole lamination on the axle be should guarantee during closed assembly, axle center line of bolt hole and pole core axis normal made again.And for the ease of the processing of axle, it is circular that axle is generally, therefore when the pole core closed assembly, center roller carries out circumferential registration because of failing, axle can arbitrarily be rotated in pole core, on technology, be difficult to guarantee axle center line of bolt hole and pole core axis normal, therefore often appearance because of the requirement that do not reach axle center line of bolt hole and pole core axis verticality to the pole core phenomenon of doing over again, time-consuming.
The utility model content
The technical problems to be solved in the utility model is: the pole core axle orientation tool that a kind of screw rod fixed magnetic pole is provided, can play when the pole core closed assembly, the screw on the maintenance axle and the square screw slot position consistency of pole lamination of pole core, and the effect that keeps axle center line of bolt hole and pole core axis normal.
The technical solution of the utility model is: a kind of pole core axle orientation tool of screw rod fixed magnetic pole, comprise positioning screw, positioning sleeve, pin, positioning sleeve is positive cuboid, and there is circular hole the centre, and the positioning sleeve lateral surface matches with the square screw slot of pole lamination; Positioning screw upper end be positive cuboid, the positioning screw middle part be positive cuboid and with positioning sleeve centre circular hole employing matched in clearance, the positioning screw lower end is a screw thread, is screwed in the screw of pole core axle; Pin penetrates the positioning screw middle part above positioning sleeve.
The beneficial effects of the utility model are: because the positioning sleeve lateral surface matches with the square screw slot of pole lamination, match with circular hole in the middle of the positioning sleeve in the positioning screw middle part, the positioning screw lower end is adopted with the pole core axle and is threaded, when the pole core closed assembly, kept screw and the square screw slot position consistency of pole lamination on the axle, keep axle center line of bolt hole and pole core axis normal, improved effect.
Description of drawings
Fig. 1 is the utility model scheme of installation.
Each unit number is among the figure: the 1-positioning screw; The 2-positioning sleeve; The 3-pin; The square screw slot of 4-pole lamination; 5-pole core axle; The 6-pole core.
The specific embodiment
Embodiment 1: as shown in Figure 1, the pole core axle orientation tool of screw rod fixed magnetic pole comprises positioning screw 1, positioning sleeve 2, pin 3, and positioning sleeve 2 is positive cuboid, and there is circular hole the centre, and positioning sleeve 2 lateral surfaces match with the square screw slot 4 of pole lamination; Described positioning screw 1 upper end is positive cuboid, so that turn with small tool, positioning screw 1 middle part be positive cuboid and with positioning sleeve 2 in the middle of circular holes adopt matched in clearance, so that cooperate between positioning sleeve 2 and the positioning screw 1 closely, and positioning screw 1 can be in positioning sleeve 2 be rotated, positioning screw 1 lower end is a screw thread, is screwed in the screw of pole core axle 5; Pin 3 penetrates positioning screw 1 middle part above positioning sleeve 2, drop out to prevent positioning sleeve 2.
When pole core 6 closed assemblies, after carrying out lamination earlier, penetrate axle 5 by operation, positioning screw 1 lower end of the utility model orientation tool is screwed in the screwed hole of pole core axle 5, simultaneously positioning sleeve 2 is inserted in the square screw slot 4 of pole core, and pin 3 penetrated positioning screw 1 middle part, center roller 5 positions and fixes, and can carry out follow-up pole core closed assembly operation.
