Assembling tool for shell and stator of direct drive motor

Abstract

The invention discloses an assembling tool for a shell and a stator of a direct drive motor. The assembling tool comprises a base, guide rods, a support ring and a guide ring. The upper end of the base is connected with the guide rods. A base boss is arranged in the center of the upper end face of the base. The support ring is installed on the upper end face of the base. A stator is attached to the outer wall of the base boss. The lower end face of the stator abuts against the support ring in an attached mode. The guide ring comprises a mounting table, and a mounting table lower bulge is formed on the lower end face of the mounting table. Lower bulge through holes penetrating through the inner and outer walls are formed in the mounting table lower bulge. The inner end of each lower bulge through hole abuts against a ball. The inner ends of the balls are exposed out of the lower bulge through holes and abut against the outer wall of the stator. A heat insulation ring is arranged on theupper end face of the mounting table, and the heat insulation ring abuts against the shell in an attached mode. The shell includes a second shell body matched with the stator. The shell is pressed downwards to drive the guide ring to be pressed downwards along with the guide rod so that the second shell body can be pressed into the outer wall of the stator in an interference fit manner. In the invention, the stator is fixed reliably and firmly, the temperature of the shell will not decrease rapidly, and the assembly of the shell and the stator is premise, reliable and efficient.

Description

technical field

[0001] The invention relates to the field of assembly tooling for motor components, and more specifically relates to an assembly tooling for a casing and a stator of a direct drive motor. Background technique

[0002] Due to its low speed and high output torque characteristics, direct drive motors are also called torque servos. Unlike traditional motors, direct drive motors can be directly connected to the load, thus eliminating the need for reduction transmission mechanisms such as reducers and gearboxes. The structure is simple and easy to assemble. It is convenient and maintenance-free, so it is widely used in some industries.

[0003] The direct drive motor is mainly composed of casing, stator, rotor, end cover and other components. The iron core part of the stator is integral, and the stator is installed into the casing through interference fit. Due to the high output torque of the direct drive motor, in order to To ensure the stability of the stator, t...
