Description

Multifunctional motor test installation device and method

technical field

The invention relates to the technical field of motor testing tooling, in particular to a multifunctional motor testing installation device and method.

Background technique

In the existing motor test bench, the motor test installation platform cannot be lifted and moved. Motors with different frame sizes can only be installed by building block-type pads, and then the motor base is fixed by tie rod bolts and pressure plates. These test devices have the following problems: 1. Low installation efficiency: During installation, pads of different specifications are usually used to pad the four corners of the motor. Since they need to be padd at the same time, and the specifications of pads at the four corners need to be the same, it requires at least two Individuals add spacers on both sides of the motor at the same time. For motor test installations with larger weight and volume, 4 people are required. Most of the work is wasted on the installation of building blocks. More than 80% of the time is spent on motor installation for the test of one motor. 2. Great danger: During the installation of the motor, the height of a single pad is small and the size of the plane is small. The four corners are padded with pads of different specifications to form a column, the height is high, there is no guide, the motor seat is on the top, and the pads The masonry column structure is easy to collapse, and the installation process poses a great safety risk to the installer and the motor itself. 3. There are many tools required: the center height of the motor and the flange are various. In order to align the axis of the tested motor with the center of the mounting flange hole, spacers of different specifications are required, and flange-mounted motors are also required. Flange mounting plates of different specifications. 4. The installation is not firm. The long slender cylindrical structure cushioned by the small spacer block is only at the four corners of the motor, and is fixed by the tie rod bolts and the pressure plate. The installation structure is a cubic structure, which is very unstable. 5. Low installation accuracy. Manually built spacers, the position of the four corners of the motor is asymmetrical, the position of the pressure plate is asymmetrical, the pulling force of the tie rod bolts is not uniform, and the length of the tie rod bolts is inconsistent, which will cause the motor shaft to be uneven; Masonry slender column structure support, 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. Affect the test accuracy. During the test, the motor under test was twisted and vibrated, and the long and thin cylindrical 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.
