Abstract
The invention discloses a method for eliminating the stress of a silicon steel sheet laminated motor base by means of efficient and high energy. According to the method, an impact tool is used to impact the surface of a motor base (mainly the position of welding of the motor base) at a frequency of more than twenty thousand times per second, due to the high-frequency, efficient and large energy under focusing, severe compression plastic deformation happens to a metal surface layer, an original stress field is changed at the same time, a certain value of pressure stress is generated, and the impacted position is reinforced. According to the method for eliminating the stress of the silicon steel sheet laminated motor base, the stress of the motor base is effectively eliminated, and deformation of coaxiality and ovality of seam allowances at the front end and at the rear end of the machined motor base is effectively controlled; the physical air gap between a stator and a rotor of a motor is evener, assembly of the motor is facilitated, and abnormal noise of the motor is effectively lowered, and the performance of the motor is improved.
Description
technical field
The present invention relates to the motor manufacturing technology field.
Background technology
Silicon steel sheet lamination electric machine stand is because the silicon steel sheet plated film can not carry out high-temperature process at present, after welding, can only carry out the after-baking of 240 ℃ of low temperature dehydrogenations, to the elimination of welding stress seldom, usually occur that support front and back end axiality, seam ovality dimension overproof are serious, affect quality of motors, produce the different sound of motor, affect motor quality.Therefore the problem that needs solution must not high-temperature heat treatment silicon steel sheet lamination electric machine stand to eliminate stress.
Through retrieval, do not find identical domestic prior art.
Summary of the invention
Technical problem to be solved by this invention is the silicon steel sheet lamination motor to not carrying out high-temperature heat treatment while eliminating stress, and how to eliminate support stress, improves quality after processing, controls frame deformation, guarantees motor quality.
Technical scheme of the present invention is: described high frequency high-energy is eliminated silicon steel sheet lamination electric machine stand strain method, utilize high frequency high-energy generating means, high frequency, efficient macro-energy occur, by impact head with per second the frequency more than 20,000 times impact the electric machine stand metal surface, make matallic surface layer produce compressive plastic deformation, change original stress field simultaneously, produce the compression of certain numerical value, strengthening, by impact site, is eliminated silicon steel sheet lamination electric machine stand stress.
In said method, described support surface is mainly the position while welding of support metal surface by impact site.
In said method, by adopting the high-octane impact of high frequency, after the control frame manufacture, the deflection of front and back end seam axiality and seam ovality, make the physics air gap between motor stator and rotor even.
Adopt the present invention, can eliminate silicon steel sheet lamination electric machine stand stress, electric machine stand stress is effectively eliminated, after frame manufacture, the deflection of front and back end seam axiality and seam ovality is effectively controlled.Physics air gap in motor provided by the present invention between stator and rotor is more even, is convenient to the assembling of motor, effectively reduces the different sound of motor, improves motor performance.
The accompanying drawing explanation
Fig. 1 is the use schematic diagram that high frequency high-energy of the present invention is eliminated the method for silicon steel sheet electric machine stand stress.
In figure: 1, high frequency high energy generating means; 2, impact head; 3, weld seam; 4, motor front end trim ring; 5, silicon steel sheet; 6, motor rear end trim ring.
Embodiment
As shown in Figure 1, described motor comprises motor front end trim ring 4, silicon steel sheet 5, motor rear end trim ring 6; There is weld seam 3 on the electric machine stand surface.Utilize high frequency high-energy generating means 1, high frequency, efficient macro-energy occur, by adopting impact head 2 transferring energies to the electric machine stand metal surface, frequency with per second more than 20,000 times is impacted metal surface (being mainly weld seam 3 positions of support), due to high frequency, efficient and focus on lower macro-energy, make the larger compressive plastic deformation of matallic surface layer generation, thereby changed original stress field, produce the compression of certain numerical value, and impact site is strengthened.Adopt the method to eliminate silicon steel sheet lamination electric machine stand stress, electric machine stand stress is effectively eliminated, after frame manufacture, the deflection of front and back end seam axiality and seam ovality is effectively controlled.Physics air gap in motor provided by the present invention between stator and rotor is more even, is convenient to the assembling of motor, effectively reduces the different sound of motor, improves motor performance.
The embodiment of the invention discloses a kind of high frequency high-energy and eliminate the method for silicon steel sheet electric machine stand stress, avoid being out of shape after frame manufacture, improved quality of motors, effectively changed the different sound of motor, thereby reach the purpose that improves motor quality.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all being included in protection scope of the present invention.
