Problems solved by technology

[0002] High-end, low-power and small-volume servo motors have always been a weak point in my country's motor industry. The reason is that the size of small servo motors is too small and difficult to assemble. However, small servo motors themselves require certain mechanical precision. Generally, servo motors are assembled first. After heating the stator casing, the wound iron core is pressed into the casing, but because the wound iron core is made of multiple stator cores spliced ​​and inlaid, it is very easy to deform and disperse when pressed in, so a design is made New tooling is necessary to assist core assembly

Embodiment

[0019] First, nine stator cores 41 are spliced ​​and inlaid around the center of the circle to form a circular wound stator 4, and then copper wires 5 are wound on the wound stator 4, and at the same time, insulating punches are sleeved on the wound stator 4 6. After completing the above preparatory work, first connect the hoop stator sleeve 2 to the outer surface of the stator sleeve 1, then insert the winding stator 4 into one end of the stator sleeve 1, and then install the assembly on the press On the machine, the stator housing 3 is then heated to ensure that the temperature of the stator housing 3 reaches 180°C, and finally the stator housing 3 is pressed on the outer ring of the assembly by a press.

Abstract

The invention relates to a stator pressing tool for a motor. The stator pressing tool for the motor comprises a stator sleeve and a stator hooping sleeve. The stator sleeve is sleeved with the stator hooping sleeve. One end of the stator sleeve is inserted in the inner side face of one end of a stator shell. A wire winding stator is arranged in the stator shell. One end of the wire winding stator is inserted in the inner side face of the stator sleeve. According to the stator pressing tool for the motor, a stator is fixed so that when the stator is pressed into a machine shell, the phenomenon that the stator is parted due to pressure can be avoided, the production efficiency of the motor is greatly improved, and the stator pressing tool for the motor further has the advantages of being simple in structure, convenient to operate and the like.

Description

technical field [0001] The invention relates to the field of stator tooling, in particular to a motor pressing stator tooling. Background technique [0002] High-end, low-power and small-volume servo motors have always been a weak point in my country's motor industry. The reason is that the size of small servo motors is too small and difficult to assemble. However, small servo motors themselves require certain mechanical precision. Generally, servo motors are assembled first. After heating the stator casing, the wound iron core is pressed into the casing, but because the wound iron core is made of multiple stator cores spliced ​​and inlaid, it is very easy to deform and disperse when pressed in, so a design is made New tooling is necessary to aid in core assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor stator pressing tool, which has a simple structure and is easy to use, greatly improves the spee...
