Abstract

The invention discloses a discontinuous rotor shrinkage fit assembly device, and relates to a rotor shrinkage fit assembly device. The invention solves the problems that for an existing rotor shrinkage fit assembling device, it is difficult to guarantee the coaxiality of rotor parts, the heating environment temperature is uncontrollable and uneven in distribution, and a rotor shaft hole is damaged in the assembling process. Fixing supports are evenly distributed on the upper end face of a base in the circumferential direction, one end of a heating cylinder fixing frame is connected with the middle of the corresponding fixing support, the other end of the heating cylinder fixing frame is connected with a heating cylinder, one end of each upper claw disc length adjusting device is connected with the upper portion of the corresponding fixing support, one end of each lower claw disc length adjusting device is connected with the lower portion of the corresponding fixing support, the other end of each upper claw disc length adjusting device is connected with an upper claw disc through a connecting rod, the other end of each lower claw disc length adjusting device is connected with a lower claw disc through a connecting rod, and each set of heating tiles and each set of thermocouples are evenly distributed in the circumferential direction of the heating cylinder and arranged alternately. The device is used for discontinuous rotor shrinkage fit assembling.

Description

technical field [0001] The invention relates to a shrink fitting device, in particular to a discontinuous rotor shrink fitting device, which belongs to the technical field of motor assembly. Background technique [0002] In the rotating machinery production industry, the assembly of the rotor has always been the core issue in equipment manufacturing. The rotor shrink-fit process must not only ensure the coaxiality of the rotor, but also ensure the precise positioning of the connecting flange, which puts forward high requirements on the uniformity of rotor positioning and thermal deformation. [0003] However, the heating environment temperature of the existing rotor shrink-fit assembly device is uncontrollable and unevenly distributed, it is difficult to ensure the coaxiality of the rotor parts, and it is easy to cause damage to the rotor shaft hole during the assembly process. Contents of the invention [0004] The present invention aims to solve the problems that the he...
