A motor mounting mechanism with a centering and positioning structure

Abstract

This utility model proposes a motor mounting mechanism with a centering and positioning structure, which includes a support and bearing component, a transition and positioning component, a motor assembly component, a load assembly component, and a drive and mating component. This mounting mechanism utilizes a drive screw with both positive and negative threads, allowing the motor assembly component and the load assembly component to move synchronously in opposite directions with a single handwheel operation. This fundamentally ensures automatic centering of their axes, eliminating the accumulated errors of traditional step-by-step adjustments. The load side employs a pneumatic clamping frame to firmly and accurately lock the load shaft and maintain its correspondence with the motor shaft. The buffer locking design of the motor frame facilitates rapid installation and fixation of the motor. The entire mechanism is built within a rigid and stable support and positioning space, supplemented by dual guidance from sliding guide rails and drive guide rods, ensuring smooth and precise movement and significantly improving installation efficiency, centering accuracy, and the overall stability of the transmission system.

Description

Technical Field

[0001] This utility model relates to motor production and testing equipment, and more particularly to a motor mounting mechanism with a centering and positioning structure. Background Technology

[0002] Patent document CN210323290U discloses a motor testing alignment device. The test frame is bolted to an adapter plate, which is bolted to the motor. The coupling has a splined front end for connecting to the motor's output, and a flange at the rear end for connecting to the dynamometer's input. A horizontal fixing block is bolted to the adapter plate, and the bolts on the horizontal fixing block are used for fine-tuning the vertical alignment of the adapter plate. A vertical fixing block is bolted to a fixed frame, and the bolts on the vertical fixing block are used for fine-tuning the horizontal alignment of the adapter plate. However, this alignment device relies on step-by-step fine-tuning with bolts in the horizontal and vertical directions. Essentially, it's a manual coarse-adjustment method dependent on human experience, which makes it difficult to guarantee the accuracy and reliability of shaft alignment at high speeds, and the operation is cumbersome and time-consuming. Therefore, it is necessary to optimize its structure to overcome these shortcomings. Summary of the Invention
