Multifunctional Mecanum wheel size and performance comprehensive test bench

Abstract

The invention belongs to the technical field of Mecanum wheel performance testing, and particularly relates to a multifunctional Mecanum wheel size and performance comprehensive test bench which comprises a driving device and a testing device, the testing device comprises a workbench, and third guide rails are fixedly installed at the top of the workbench. The third guide rails are perpendicular to the outer walls of the left side and the right side of the workbench in position, the two sets of third guide rails are symmetrically arranged, the tops of the two sets of third guide rails are slidably connected with a sliding frame, a second displacement sensor is fixedly installed on the outer wall of the left side of the sliding frame, and second guide rails are arranged on the left sides of the third guide rails and fixedly installed on the top of the workbench; and two groups of the second guide rails are symmetrically arranged. The multifunctional Mecanum wheel size and performance comprehensive test benchhas the advantages that a driving motor drives a Mecanum wheel to rotate, the size information is tested under the no-load condition, the performance of the Mecanum wheel is measured under the heavy-load condition, simulation loading is conducted through the loading oil cylinder, and a detection wheel simulates ground resistance through overturning of the damping motor.

Description

technical field [0001] The invention relates to the technical field of mecanum wheel performance testing, in particular to a multifunctional mecanum wheel size and performance comprehensive testing platform. Background technique [0002] The omnidirectional movement of the mecanum wheel is based on the principle of a central wheel with a number of axles located at the periphery of the wheel. These angled peripheral axles convert a portion of the wheel steering force into a wheel normal force. , there are many small rollers distributed obliquely on its rim, so the wheel can slide laterally. The generatrix of the small rollers is very special. When the wheel rotates around the fixed wheel mandrel, the envelope of each small roller The thread is cylindrical and can roll forward continuously. The Mecanum wheel has a compact structure and flexible movement, and is a very successful omnidirectional wheel. [0003] Mecanum wheel testing is currently used to test the mechanical pro...

AI Technical Summary

Problems solved by technology

Because the mecanum wheel has a multi-stick structure, simply testing one roller may easily lead to an increase in the deviation from the actual load requirement of the entire wheel, and the measurement results are relatively one-sided. There are also overall measurement of the mecanum wheel on the market, but the measurement is accurate. The parameters are limited, so an experimental device for comprehensive testing of the Mecanum wheel is needed to accurately measure its dimensional accuracy, performance, etc.

[0004] The prior art has the following deficiencies: the existing Chinese patent CN105466702A discloses a comprehensive detection and testing experimental device for mecanum wheels, which is provided with a vertical loading system and a ground simulation device to measure the load and motion performance of the mecanum wheels. Mainly carry out the load-carrying experiment, the beating of the mecanum wheel and the overall contour projection cannot be collected, and the change of the drive motor power and the magnitude of the axial force generated under different load conditions cannot be known. In addition, the conveyor belt similar to the tank chain is used to simulate the ground. Not only is it easy to damage but the seams can damage the mecanum wheels, especially under heavy loads
