Abstract
The utility model discloses a kind of rotor punchings, punching ontology including being in disc-shaped, the punching body central is axis hole, eight magnet slots have been evenly spaced on along punching body peripheral face, the magnet slot is connected with right flank section by symmetrical left wing's section and is formed, and the angle between left wing's section and right flank section is 160 °；It further include thermovent, uniform intervals of the thermovent centered on axis hole are uniformly arranged on punching ontology, and the thermovent is provided with a riveted holes between axis hole and magnet slot, per two adjacent thermovents.By riveting the design at platform, tradition is changed by mode is welded and fixed, mounting process is simplified, greatly improves working efficiency, deformation caused by electric welding is avoided, ensure that the uniformity of flute profile.
Description
Technical field
The utility model relates to technical field of motors, and in particular to a kind of rotor punching.
Background technique
Existing rotor punching generally passes through electric welding and is mutually permanently connected, such as in rotor punching fixed by four axis holes at present
In piece, need the position fixation of four welding guns being welded into platform, but practical operation is difficult to fix, welding bar is often broken needs
Secondary welding, welding process heavy workload, working efficiency is low, and Internal Hole Deformation amount brings later period installation permanent magnet
Certain difficulty.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and propose that one kind is structurally reasonable,
It is easy to operate, simplify mounting process, improves the rotor punching of working efficiency.
The technical scheme in the invention for solving the above technical problem is：A kind of rotor punching, including in disc-shaped
Punching ontology, the punching body central are axis hole, have been evenly spaced on eight magnet slots along punching body peripheral face, described
Magnet slot is connected with right flank section by symmetrical left wing's section and is formed, and the angle between left wing's section and right flank section is 160 °；Also wrap
Thermovent is included, uniform intervals of the thermovent centered on axis hole are uniformly arranged on punching ontology, and the thermovent is located at
Between axis hole and magnet slot, a riveted holes are provided with per two adjacent thermovents.By riveting the design at platform, change
It is traditional to simplify mounting process by mode is welded and fixed, greatly improve working efficiency, avoid change caused by electric welding
Shape ensure that the uniformity of flute profile.
Preferably, magnet slot left wing section lower left side has 66 ° of lobe formations, magnet slot right flank section lower right side has
66 ° of lobe formations, left wing's section of strip, right flank section composition have the structure of angle, have guiding when installing magnet coil
Effect, it is smaller to the abrasion of magnet coil.
Preferably, thermovent is provided with eight, the riveted holes are provided with eight, and thermovent is arranged in axis hole and magnet
Between slot, rate of heat dissipation on the one hand can be improved, on the other hand can effectively reduce rejection rate.
The utility model compared with prior art, has the following advantages that and effect：1, by riveting the design at platform, change
It is traditional to simplify mounting process by mode is welded and fixed, greatly improve working efficiency, avoid change caused by electric welding
Shape ensure that the uniformity of flute profile；2, left wing's section of strip, right flank section composition have the structure of angle, in installation magnet wire
There is guiding role when circle, it is smaller to the abrasion of magnet coil；3, thermovent is arranged between axis hole and magnet slot, on the one hand may be used
Rate of heat dissipation is improved, rejection rate on the other hand can be effectively reduced.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram.
Fig. 2 is the utility model embodiment magnet slot structure schematic diagram.
In figure：Punching ontology 1, axis hole 2, magnet slot 3, left wing's section 4, right flank section 5, lobe formation 6, thermovent 7, riveted holes
8, left wing section and right flank section between angle α 1, lobe formation angle α 2.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Referring to Fig. 1-2, rotor punching includes the punching ontology 1 of rounded structure in the present embodiment, and 1 center of punching ontology is
Axis hole 2 has been evenly spaced on eight magnet slots 3 along 1 outer peripheral surface of punching ontology, and magnet slot 3 is by symmetrical left wing's section 4 and right flank
5 connection composition of section, the angle α between left wing's section and right flank section is 160 °, and magnet slot left wing 4 lower left side of section have lobe formation 6,
5 lower right side of magnet slot right flank section has lobe formation 6, and the angle α 2 of the lobe formation is 66 °, left wing's section 4, right flank of strip
5 composition of section has the structure of angle, has guiding role when installing magnet coil, smaller to the abrasion of magnet coil.
Uniform intervals of eight thermovents 7 of the present embodiment centered on axis hole are uniformly arranged on punching ontology 1, thermovent
7 between axis hole 2 and magnet slot 3, is provided with a riveted holes 8 per two adjacent thermovents 7, on the one hand can be improved scattered
On the other hand heating rate can effectively reduce rejection rate.
The present embodiment, at the design of platform, is changed tradition by mode is welded and fixed, simplifies mounting process by riveting,
Working efficiency is greatly improved, deformation caused by electric welding is avoided, ensure that the uniformity of flute profile.
In addition, it should be noted that, all structure, feature and principles according to the utility model patent concept done it is equivalent
Variation or simple change, are included in the protection scope of the utility model patent.
