Abstract

The invention relates to an assembly technology of a fan-shaped slice rotor core. The assembly technology comprises the following steps: evenly putting gaskets between a wheel disk connected with a wheel disk shaft and dovetail blocks in an axial length, and then screwing hexagon socket screws; taking off the gaskets, carrying out an iron core lamination; penetrating into copper bars after the lamination is ended, and then axially pre-tightening the iron core; tightening taper keys under the condition of ensuring circumferential gaps between the dovetail blocks and a punching plate; pre-tightening the iron core again after preheating the iron core, and tightening the taper keys between the dovetail blocks and the punching plate; and welding the wheel disk of the wheel disk shaft and the dovetail blocks. The assembly technology provided by the invention has the characteristics that the iron core is convenient to laminate; the copper bars are easy to penetrate; and a rotor does not deform after a motor runs.

Description

A kind of fanning strip rotor core assembly technology
Technical field
The present invention relates to a kind of fanning strip rotor core assembly technology.
Background technology
General fanning strip rotor core assembly technology is with Bolt Connection wheel disk shaft disc and dove tail block, but not pretension bolt, after pre-installing axial upper, middle and lower three iron leg core and determining the locus of dove tail block, the location hole that drills and reams in the non-lamination position of dove tail block also makes alignment pin, then remove three iron leg cores of prepackage, after welding wheel disk shaft disc and dove tail block after coupling bolt, carry out lamination; Due to the existence of welding deformation, the locus of dove tail block is changed, can not carry out smoothly during fanning strip 1/2 closed assembly, and cause the iron core gap after lamination to diminish, grooved size can not be ensured, make copper bar penetrate difficulty; Also cause during taper key hammering is that punching is moved simultaneously, cannot ensure iron core and key contacts area and quality, occur the phenomenons such as iron core side rejection tablet, taper key loosen after motor runs a period of time, and initiation motor oscillating, copper bar snap fracture etc.
Summary of the invention
The present invention seeks to solve that the iron core slot molded dimension that causes of general fanning strip rotor core assembly technology can not ensure, copper bar penetrates the defects such as difficulty, iron core and key contacts area deficiency after lamination, avoids the generation of associated motor quality problems.
The present invention is achieved in that a kind of fanning strip rotor core assembly technology, comprises the following steps:
Step one, when wheel disk shaft disc connects with dove tail block, wheel disk shaft disc and dove tail interblock axial length is evenly placed after adjusting pad, is screwed by attachment bolt;
Step 2, takes away wheel disk shaft disc and dove tail interblock adjusts pad, ensures dove tail block energy circumference and radial direction slightly movement when stressed, and carries out lamination in this case;
Step 3, after completing lamination, is having precompressed iron core in groove lining bar situation to drawing requirement length, to remove pressure, after penetrating copper bar in a free state, is exerting pressure and pretension tightening bolt to iron core by adjustment dove tail block;
Step 4, rotor is set level, and squeezes into the taper key between dove tail block and punching, symmetrical urgent taper key under each dove tail block of guarantee and punching circular gap deviation are less than 0.15mm situation;
Step 5, by iron core preheating more than 100 DEG C, pretension iron core tightening bolt, taper key between urgent dove tail block and punching ensure gap uniformity again;
Step 6, until iron core cooling after, wheel disk shaft disc and dove tail block are symmetrically welded integral after carry out copper bar and end ring medium frequency welding;
By producing checking, assembly technology core lamination stack of the present invention is convenient, copper bar penetrates easily, iron core coordinates with the enough gross areas of bond energy, both improves production efficiency, and in turn ensure that the total quality of rotor.
Accompanying drawing explanation
Fig. 1 is the schematic diagram after a kind of fanning strip rotor core assembly technology completing steps six of the present invention, in figure: 1. wheel disk shaft; 2. fanning strip; 3. dove tail block; 4. taper key; 5. attachment bolt; 6. copper bar.
Embodiment
A kind of fanning strip rotor core assembly technology of the present invention, comprises the following steps:
Step one, when wheel disk shaft disc connects with dove tail block, after wheel disk shaft disc and dove tail interblock axial length evenly put 0.5mm pad, screws attachment bolt torque spanner with identical power;
Step 2, takes away wheel disk shaft disc and dove tail interblock adjusts pad, ensures dove tail block energy circumference and radial direction slightly movement when being subject to impulsive force, and carries out lamination in this case;
Step 3, after completing lamination, is having precompressed iron core in groove lining bar situation to drawing requirement length, to remove pressure, after penetrating copper bar in a free state, is exerting pressure and pretension tightening bolt to iron core by fine setting dove tail block;
Step 4, rotor is set level, and squeezes into the taper key between dove tail block and punching, symmetrical urgent taper key under each dove tail block of guarantee and punching circular gap deviation are less than 0.15mm situation;
Step 5, by iron core preheating more than 100 DEG C, pretension iron core stretching screw, taper key between urgent dove tail block and punching ensure gap uniformity again;
Step 6, until iron core cooling after, wheel disk shaft disc and dove tail block are symmetrically welded integral after carry out copper bar and end ring medium frequency welding.
