Problems solved by technology

[0003] During the processing of the dry motor rotor, heat shrink treatment is required. However, the existing dry motor rotor heat shrink device is generally not convenient for positioning and locking the motor rotor. Shaking, so that it is inconvenient to perform shrink-fit operation; at the same time, it is inconvenient to adjust the position of the existing dry-type motor rotor shrink-fit device, so that it is inconvenient for the staff to place the motor rotor in the locking mechanism for locking, which brings inconvenience to the staff.

Abstract

The invention discloses a positioning device for a dry-type motor rotor hot jacket. The positioning device comprises a bottom plate and at least one group of positioning assemblies rotationally connected to the bottom plate. The positioning assembly comprises a fixed clamping plate, a movable clamping plate and a bearing plate. The lower end of the fixed clamping plate is vertically and fixedly connected with a fixed plate. The fixed plate is rotatably connected to the upper surface of the bottom plate. The movable clamping plate is connected to the upper portion of the fixing plate through anadjusting mechanism. The bearing plates are symmetrically and fixedly connected to the left side wall and the right side wall of the fixed clamping plate. The bearing plate is positioned between themovable clamping plate and the fixed clamping plate. An accommodating space is formed upwards on the lower end surface of the bearing plate. According to the invention, a dry-type motor rotor is positioned and locked before the hot jacket treatment of the dry-type motor rotor. Therefore, the position of the locked dry-type motor rotor can be conveniently adjusted. As a result, the hot jacket treatment of the dry-type motor rotor can be facilitated.

Description

technical field [0001] The invention relates to the technical field of dry-type motor rotor thermal sleeve processing equipment, in particular to a positioning device for dry-type motor rotor thermal sleeve. Background technique [0002] The rotor is the main part of high-speed rotation in motor power machinery or working machinery. The main rotor rotates at high speed. When its speed is close to the critical speed, the shaft will be deflected and deformed, and even mechanical damage will be caused by resonance. The natural frequency of the transverse vibration of the rotor is multi-order Therefore, the corresponding critical speed is also multi-order. When the working speed of the rotor is lower than the first-order critical speed, it is called a rigid rotor, and when the working speed of the rotor is higher than the first-order critical speed, it is called a flexible rotor. [0003] During the processing of the dry motor rotor, heat shrink treatment is required. However, t...
