Abstract

The utility model discloses a rotor of a permanent-magnet machine with lamination poles. The rotor comprises a rotor piece which is punched by an inner wafer left after the punching of a stator piece, an shaft hole is formed on the rotor piece, a main shaft is mounted in the shaft hole, and a permanent magnet is fixed on the outer side of the rotor piece. The rotor in the permanent-magnet machine is punched by the inner wafer left after the punching of the stator piece, thereby fully utilizing silicon sheet material, adopting the simple punch production process, and reducing the manufacturing cost by replacing the precision-finishing production process of various machine tools. Therefore, the rotor is convenient for batch production.

Description

A kind of punching sheet magnetic pole permanent magnet motor rotor
Technical field
The utility model relates to a kind of permanent magnet machine rotor.
Background technology
Developing rapidly of magneto, its rotor structure be variation also.In the prior art, be processed into the magneto of magnetic pole with magnet steel, the interior disk that stays behind its punching out stator piece will be made other purposes, and utilance is not high.Be processed into magnetic pole with magnet steel, need in its course of processing with multiple lathe (for example sawing machine, forging and pressing bed, lathe, planer, milling machine, grinding machine or machining center etc.), employing the skilled worker carries out hard to tackle work flow, and production efficiency is not high.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of permanent magnet machine rotor that utilizes the interior disk punching out rotor sheet that stays behind the punching out stator piece, and material is fully used.
In order to solve the problems of the technologies described above, a kind of punching sheet magnetic pole permanent magnet motor rotor of the present utility model comprises rotor sheet, described rotor sheet is formed by the remaining interior disk punching out of punching out stator piece, have axis hole in the rotor sheet, main shaft is installed in the axis hole, the rotor sheet outside is fixed with permanent magnet.
As improvement of the technical scheme, the described shaft hole inner wall and the main shaft outside are respectively arranged with first, second keyway, in this first, second keyway flat key are installed.
As improvement of the technical scheme, the arranged outside of described rotor sheet has cavity, and described permanent magnet is inlaid in this cavity; Have the through hole that runs through two end face on the described rotor sheet, two end faces of rotor sheet are respectively arranged with first, second pressing plate, and the locating pin of fixing first, second pressing plate is installed in the described through hole.
The beneficial effects of the utility model are: this punching sheet magnetic pole permanent magnet motor rotor is owing to adopt said structure, utilize the remaining interior disk punching out rotor sheet of punching out stator piece, can make full use of silicon steel material, simultaneously can utilize easy punching production flow process, replace the Precision Machining production procedure of hard to tackle multiple lathe, thereby reduce production costs, be convenient to produce in batches.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a part sectional structure schematic diagram of the present utility model;
Fig. 3 is an A place structure enlarged drawing among Fig. 1.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of punching sheet magnetic pole permanent magnet motor rotor of the present utility model comprises rotor sheet 1, described rotor sheet 1 is formed by the remaining interior disk punching out of punching out stator piece, have axis hole 2 in the rotor sheet 1, main shaft 3 is installed in the axis hole 2, rotor sheet 1 outside is fixed with permanent magnet 4.This punching sheet magnetic pole permanent magnet motor rotor utilizes the remaining interior disk punching out rotor sheet of punching out stator piece, can make full use of silicon steel material, simultaneously can utilize easy punching production flow process, replace the Precision Machining production procedure of hard to tackle multiple lathe, thereby reduce production costs, be convenient to produce in batches.
In the present embodiment, described axis hole 2 inwalls and main shaft 3 outsides are respectively arranged with first, second keyway 21,31, in this first, second keyway 21,31 flat key 5 are installed.The arranged outside of described rotor sheet 1 has cavity 11, and described permanent magnet 4 is inlaid in this cavity 11.Have the through hole 6 that runs through two end face on the described rotor sheet 1, two end faces of rotor sheet 1 are respectively arranged with first, second pressing plate 7,8, and the locating pin 9 of fixing first, second pressing plate 7,8 is installed in the described through hole 6.Described main shaft 3 one ends are provided with step 12, and the other end of main shaft 3 has groove 10, and the opening welding ring 13 of location first pressing plate 7 is installed in this groove 10.When laminating rotor sheet, earlier main shaft 3 there is the step end down, flat key 5 is embedded in second keyway 31, second pressing plate 8 of packing into is joined and is inserted locating pin 9, and appropriateness pad second pressing plate, 8 lower planes and ailhead, the closed assembly rotor sheet is to design length, after being fitted into first pressing plate 7 plus-minus rotor sheets and being pressed onto the position that matches with main shaft groove 10, every locating pin 9 is welded in opening welding ring of packing into 13 and welding simultaneously.After rotor press-mounting is finished, stick permanent magnet 4 at cavity 11 and just finish assembling.
In addition, have the ventilation hole 14 that runs through two end face on the described rotor sheet 1, the radiating effect when improving working rotor.
