AI Technical Summary

Technical Problem

In the existing technology, the expansion efficiency of the motor stator cooling tube is low, and the position of the expansion cylinder needs to be adjusted multiple times, which increases the operation time and workload.

Method used

The system combines an adjusting frame with a rotating assembly. The rotating assembly drives the adjusting frame to rotate, causing the expansion cylinder to rotate accordingly. This reduces the number of adjustments required, and the support mechanism improves the stability and positioning accuracy of the adjusting frame.

Benefits of technology

It improves the expansion efficiency of motor stator cooling tubes, reduces operation time and workload, extends the service life of drive components, and expands the scope of application.

Abstract

The application relates to an automatic pipe expanding machine for motor stator cooling pipes and relates to the technical field of motor cooling. The automatic pipe expanding machine for motor stator cooling pipes comprises a machine body, an adjusting frame and a rotating assembly are further arranged on the machine body, the adjusting frame is rotationally connected with the machine body, a pipe expanding cylinder and an adjusting assembly are further arranged on the adjusting frame, the pipe expanding cylinder is slidingly connected with the adjusting frame, the adjusting assembly is used for driving the pipe expanding cylinder to slide, the telescopic direction of the pipe expanding cylinder piston rod is parallel to the rotating axis direction of the adjusting frame, and the rotating assembly is used for driving the adjusting frame to rotate. The application has the following effects: relevant personnel can drive the adjusting frame to rotate through the rotating assembly, the pipe expanding cylinder rotates together with the adjusting frame, the pipe expanding cylinder after rotation corresponds to other cooling pipes on the motor stator, the pipe expanding efficiency of the cooling pipes on the motor stator is improved, and the work load of the relevant personnel is effectively reduced.
