A kind of shaping tool for stator assembly of servo motor

Abstract

The invention relates to a servo motor stator assembly shaping tool which comprises a gland (1), an upper pressuring column (2) and a fixing lantern ring (3), wherein the outer side of the lower end of the gland (1) is a conical surface, the upper end of the gland (1) is connected with the upper pressuring column (2), the fixing lantern ring (3) is arranged under the gland (1), a fixing ring (4) is fixedly connected to the lower end of the fixing lantern ring (3), and the internal diameter of the fixing ring (4) is smaller than the internal diameter of the fixing lantern ring (3). The servo motor stator assembly shaping tool is simple in operation and safe to use, meanwhile avoids extrusion caused by a traditional integrated shaping tool on a stator core, saves time and labor, and greatly improves production efficiency.

Description

technical field [0001] The invention relates to the field of motor production equipment, in particular to a shaping tool for a stator assembly of a servo motor. Background technique [0002] Servo motor is a power source often used in the modern industrial field. The rotor and stator are the most important components in its internal structure. The stator assembly is stacked according to certain rules by stator punching sheets (0.35mm or 0.5mm silicon steel sheets) , connected or welded with clips, the stator punches are stacked to form a stator core, and then the wires are embedded to form a stator assembly. [0003] However, since the wire pack outside the stator is made by manually inserting the wire, it is relatively loose. If the height and thickness of the wire pack are not dealt with, it will collide with the front and rear flanges that are similarly assembled. At this time, the enameled wire will be scratched or broken, resulting in The stator assembly is damaged, an...

[0003] However, since the wire pack outside the stator is made by manually inserting the wire, it is relatively loose. If the height and thickness of the wire pack are not dealt with, it will collide with the front and rear flanges that are similarly assembled. At this time, the enameled wire will be scratched or broken, resulting in The stator assembly is damaged, and the stator assembly is scrapped, causing losses

[0004] At present, the commonly used processing method is to use a nylon rod with a handle. The end surface of the nylon rod is opened with a circular groove of the same size as the outer diameter of the wire package of the stator assembly. When using it, the nylon rod is used to cover the upper end of the stator assembly, and then Place it on a press, or hit it with a hammer, so it is easy to crush the wire package, especially if the gap between the copper core wires of the wire package is small, or there is no gap, it is difficult to shape to the required requirements, or even It is scrapped, and once the nylon rod is shifted and popped out when the press is pressed during operation, it is easy to cause a safety accident
