Medium-frequency heating and shrinking equipment of servo motor stator and using method thereof

Abstract

The invention discloses heating and shrinking equipment of a motor stator and a using method thereof. The principle of expansion with heat and contraction with cold is adopted, namely before installation, after a motor shell is heated at medium frequency, a middle hole is expanded; and after the motor stator is installed in the motor shell, the motor shell is cooled to be shrunk and positioned. The invention provides the medium-frequency heating and shrinking equipment of a servo motor stator and a using method thereof. The medium-frequency heating and shrinking equipment is simple in structure, time-saving and labor-saving in operation, low in energy consumption and high in production efficiency. The technical problems of complex process of installing the motor stator in the motor shell, easy damage of the motor stator and the motor shell, unguaranteed quality of the motor and the like in the prior art are solved. The medium-frequency heating and shrinking equipment comprises a platform, wherein a sensing coil is vertically arranged on the platform and is connected with a main power supply through a medium-frequency power supply controller; a heating cavity capable of accommodating the motor shell is arranged on the middle part of the sensing coil; a lifting device is arranged above the heating cavity; a fixture body used for clamping the motor stator is arranged on the lifting device; and a fan is arranged below the heating cavity.

Description

technical field [0001] The invention relates to a thermal sleeve device for a motor stator and a method for using the same, in particular to an intermediate frequency thermal sleeve device for a servo motor stator with fast temperature rise of the motor casing, low energy consumption and high production efficiency and a method for using the same. Background technique [0002] When assembling the servo motor, the motor stator needs to be installed in the motor casing, and the two are coaxial interference fit. The existing assembly method generally uses tools such as wooden hammers to force the motor casing into the motor stator, which is not only easy The motor stator and the motor casing are damaged, and the concentricity of the two cannot be guaranteed, so the quality of the motor cannot be guaranteed. At the same time, this assembly method is labor-intensive and low in efficiency. [0003] A Chinese patent discloses a special equipment for assembling motor stators and hous...
