Summary of the invention
The technical problem to be solved in the present invention provides a kind of fixation problem that can effectively solve electric machine iron core, Cost reduction, the disc iron fixed structure of the performance of raising motor.
In order to solve the problems of the technologies described above, disc iron fixed structure of the present invention, comprise stator core and the end cap that is fixedly mounted on the stator core end face, have some dovetail grooves of radially arranging on the end face of stator core, be provided with the metal contiguous block that can cooperate with dovetail groove in the dovetail groove, end cap is fixedly connected with the dovetail groove of stator core by the metal contiguous block.
Described metal contiguous block is set to the swallowtail-shaped structure that can match with dovetail groove, have the screwed hole that is connected with securing member on the end cap on the metal contiguous block, be connected with screwed hole by securing member after the metal contiguous block is inserted in the dovetail groove and end cap and stator core are fastenedly connected.
Described metal contiguous block comprises the swallowtail-shaped structure that can match with dovetail groove and is positioned at the outer mounting blocks of dovetail groove, have the screwed hole that is connected with securing member on the end cap on the described mounting blocks, be connected with the screwed hole of mounting blocks by securing member after the swallowtail-shaped structure of metal contiguous block is inserted in the dovetail groove and end cap and stator core are fastenedly connected.
Described metal contiguous block comprises two swallowtail-shaped structures that are oppositely arranged, one of them swallowtail-shaped structure can match with dovetail groove, another swallowtail-shaped structure can match with end cap, and two swallowtail-shaped structures are inserted into respectively in dovetail groove and the end cap and directly end cap and stator core are fastenedly connected.
After adopting above-mentioned structure, owing to have some dovetail grooves of radially arranging on the end face of the stator core that arranges, be provided with the metal contiguous block that can cooperate with dovetail groove in the dovetail groove, end cap is fixedly connected with the dovetail groove of stator core by the metal contiguous block, arrange thus and removed the welding sequence of complexity in the conventional mounting, assembly technology is required to reduce, simple to operation, be easy to realize, not only effectively reduce production cost, more be applicable to large-scale production, technical scheme of the present invention can effectively be separated the smooth problem in determinant bottom surface simultaneously, improves greatly motor performance.
