Lifting and translation motor mounting platform

Abstract

The invention relates to a lifting and translation motor mounting platform. The platform comprises a support base which is fixedly mounted; at the middle part of the upper surface of the support base,a lower table board carries out lifting movement relative to the support base under the driving of a power transmission mechanism; a limiting mechanism is mounted on each of two sides of the upper surface of the support base; a middle table board is glidingly mounted on the upper surface of the lower table board; an upper table board vertical to the movement direction of the middle table board ismounted on the upper surface of the middle table board; a servo motor I is mounted on the side surface of the middle table board; the output end of the servo motor I is connected with one end of a lead screw I through a turbine reducer; the lead screw I is penetrated in the upper table board; a guide rod is mounted at the bottom of the lower table board; a guide hole for the penetration of the guide rod is formed in the support base; and a locking mechanism for locking the guide rod is mounted on the support base on one side of the guide hole. The platform is capable of improving the mountingstability of tested motors and improving the test precision and reliability, and is convenient to operate and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of motor testing tooling, in particular to a lifting and translation motor installation platform. Background technique [0002] In traditional motor testing and installation, pads are usually used to set up building block heights, and then the motor base is fixed by tie rod bolts and pressure plates. The disadvantages are as follows: [0003] 1. Low installation efficiency. For conventional motor installation, the four corners of the motor are padded with blocks of different specifications. Since it needs to be padded at the same time, and the specifications of the pads at the four corners need to be the same, at least two people are required to add pads on both sides of the motor at the same time. For weight and Larger motor installation requires 4 people. Most of the work is wasted on the installation of building blocks. More than 80% of the time for the test of a motor is used for motor installation; 2...

AI Technical Summary

Problems solved by technology

Most of the work is wasted on the installation of building blocks. More than 80% of the time for the test of a motor is used for the installation of the motor; 2. It is very dangerous

During the installation process of the motor, the height of a single pad is small and the plane size is small. The four corners are padded with pads of different specifications to form a column shape. The height is high and there is no guide. Collapse, the installation process poses a greater safety risk to the installer and the motor itself; 3. A lot of tooling is required

The center height of the motor and the flange are various. In order to align the shaft center of the tested motor with the center of the mounting flange hole, pads of different specifications are required. For flange-mounted motors, flange mounting plates of different specifications are also required. ; 4. The installation is not firm

The long and thin cylindrical structure of the small spacer is only fixed at the four corners of the motor by tie rod bolts and pressure plates. The installation structure is a cubic structure, which is extremely unstable; 5. Low installation accuracy

Manually built pads are asymmetrical in the four corners of the motor, asymmetric in the position of the pressure plate, uneven pulling force of the tie rod bolts, inconsistent length of the tie rod bolts and other factors, which will cause the motor shaft to be uneven; It is supported by a slender column structure, and the motor is not easy to adjust in the plane

Therefore, it is difficult to align the shaft center of the tested motor with the hole center of the mounting flange; 6. It affects the test accuracy

During the test, the motor under test was twisted and vibrated, and the long and thin columnar structure built by the cushion block was easy to loosen in the center of the test process, causing the motor to vibrate or even move, affecting the test accuracy
