Description
Technical field
The utility model relates to motor production field, specifically a kind of rotor press-mounting positioning device.
Background technique
It in rotor production process, needs to position rotor sheet using positioning key, general positioning key machining accuracy
It is especially high, and cannot be accurately positioned, it is not only at high cost for production, and effect is also undesirable, it is therefore desirable to original
Positioning key improves.
Utility model content
The utility model is exactly to provide a kind of rotor press-mounting positioning device to solve the deficiencies in the prior art.
The utility model is realized according to following technical scheme.
A kind of rotor press-mounting positioning device, including lower platen, positioning key and abutment sleeve, set on the lower platen there are three
Threaded hole, positioning tie bar bottom end are inserted into threaded hole；Abutment sleeve is nested on positioning tie bar, and the installation of positioning tie bar top is useful
In the locking nut being locked in abutment sleeve on positioning tie bar；The abutment sleeve ontology is cylinder, and lateral wall forms two
Notch；The positioning key is strip structure, and one end center has threaded hole.
Further, the depth of two notch is 10mm, bottom width 16mm, the inside of notch on the abutment sleeve
Face is perpendicular to bottom surface.
Further, the positioning key includes sizes, and the width of one of positioning key is 16mm, with a thickness of
10mm, the internal diameter of center hole are 8mm.
Further, three on the lower platen are used to fix the threaded hole of three groups of positioning tie bars by the three of equilateral triangle
The orientation on a vertex arranges.
Further, three groups of abutment sleeves and positioning key are each passed through three location holes on rotor core.
The utility model obtains following beneficial effect.
The utility model can be used for the production of large-size machine equipment, the positioning compared with original positioning key, in the utility model
The straight key of the press fitting of key is adjustable in orientation, facilitates press fitting, reduces machining accuracy, and ensure that the groove profile of press fitting process
Uniformity.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
As shown in Figs 1-4, a kind of rotor press-mounting positioning device, including lower platen 4, positioning key 5 and abutment sleeve 6, it is described
It is set on lower platen 4 there are three threaded hole, 2 bottom end of positioning tie bar is inserted into threaded hole；Abutment sleeve 6 is nested on positioning tie bar 2,
2 top of positioning tie bar is equipped with the locking nut 1 for being locked in abutment sleeve 6 on positioning tie bar 2；The abutment sleeve 6
Ontology is cylinder, and lateral wall forms two notch；The positioning key 5 is strip structure, and one end center has threaded hole.
The depth of two notch is 10mm on the abutment sleeve 6, bottom width 16mm, the medial surface of notch perpendicular to
Bottom surface.
The positioning key 5 includes sizes, and the width of one of positioning key is 16mm, with a thickness of 10mm, center circle
The internal diameter in hole is 8mm.
Three threaded holes for fixing three groups of positioning tie bars 2 on the lower platen 4 are by three vertex of equilateral triangle
Orientation arrangement.
Three groups of abutment sleeves 6 and positioning key 5 are each passed through three location holes on rotor core 3.
The application method and step of the utility model are as follows: first, three positioning tie bars 2 and lower platen 4 are tightened；Second,
By 6 sets of abutment sleeve on positioning tie bar 2；Third, installs rotor core 3, and positioning tie bar 2 and abutment sleeve 6 pass through rotor iron
Three location holes on core 3；4th, select the positioning key 5 of suitable types to be inserted into the keyway on abutment sleeve 6；5th, with lock
Tight nut 1 locks positioning key 5 and abutment sleeve 6.
In above-mentioned 4th step, needed between positioning key 5 and rotor core 3 in some cases plus thin metal gasket
Piece keeps its contact closer.
The effect of the threaded hole of positioning key bottom is to stay in iron core, can will be determined with screw if unloading positioning key 5 when tire
Position key 5 is back-outed in rotor core 3 to be come.
