Innovative Lapping Experimental Platform for BR-CXD Mechanism Motion Scheme

Overview:
This set of experimental benches is an innovative comprehensive experimental platform designed specifically for undergraduate and vocational college students to innovate mechanical motion schemes, cultivate their comprehensive mechanical design ability, innovation ability, and practical assembly ability

Functional features:
This experimental platform is mainly composed of a frame, a disassembly platform, an electric motor, a belt transmission device, a low auxiliary rod group (Level II and III) cam, gears and racks, groove wheels, various rotary pairs, moving pairs, basic components and connecting parts of composite hinges. More than 60 types of planar mechanism motion schemes can be assembled on this experimental platform. The length size of the low auxiliary rod group in the experimental platform can be adjusted countless times, with a large range of length size changes, a novel joint structure, simple and convenient operation, and flexible movement, greatly improving the assembly efficiency of the mechanism's motion plan. The components of the low auxiliary rod group in the experimental platform have moderate external dimensions of the connecting parts, and all parts are ground and processed with high accuracy. The surface is blue and chrome plated, with a beautiful appearance and easy maintenance, and a long service life.

Function and characteristics of the experimental platform:
(1) This experimental platform can be conveniently and quickly overlapped on four racks to form various planar mechanism motion schemes, and the movement of the mechanism can be achieved through manual or motor drive. The parts have strong universality, high accuracy and stiffness, and are easy to disassemble and assemble during use. The mechanism has small motion error and flexible movement.
(2) The length of the connecting rod of the experimental platform can be adjusted step by step over a large range, making it convenient to install a paintbrush on the rod and scan the motion trajectory (such as the curve of the connecting rod).
Can complete experimental content:
(1) Experimental splicing design based on the principle of organizational composition;
(2) Mechanism splicing design experiment based on innovative design principles;
(3) Collaborating experiments on institutional system solutions in course design and graduation project;
Can add software features:
(1) Establish a 3D parts library; Capable of supporting current mainstream 3D software
(2) Capable of completing 3D motion simulation demonstrations for 15 typical planar mechanisms and 3 typical spatial mechanisms;
(3) Can complete virtual assembly and disassembly process explosion diagram demonstrations of 15 typical planar mechanisms and 3 typical spatial mechanisms, demonstrating the disassembly and assembly process of mechanism modules;
(4) Can complete assembly training for 15 typical planar mechanisms and 3 typical spatial mechanisms. Provide a list of required parts for the mechanism, with the function of judging the correctness of the assembly sequence of the mechanism;
(5) The software can complete virtual assembly and motion simulation.
The device has added a remote communication protocol module, which can achieve:
Remote teaching function:
1) Real time teacher and student one-on-one remote teaching, remote communication function;
2) Manufacturers and equipment administrators provide real-time guidance on equipment operation and maintenance;
Laboratory management functions:
1) The equipment is equipped with a set of laboratory management system software and hardware, implementing a one person, one account mode for administrators. Through the mobile APP communication protocol, administrators with more than 10 people can manage the equipment at any distance, including recording (automatic start) and playback of the equipment operation process, as well as automatically starting the infrared alarm function when the equipment is turned off.

Upgrade function:
After the mechanism overlap is completed, the experimental platform can also conveniently install sensors as needed to detect the displacement, angle, velocity, acceleration and other motion parameters of single or multiple mechanisms in the mechanism. By using a matching testing analyzer and software, the relationship curve of motion parameter changes can be clearly and intuitively observed on the computer.
Detection software: It can display the relationship curves of various characteristic values of test parameters and changes in various motion parameters, automatically or in combination with human-machine testing analysis, motion simulation, theoretical simulation, data saving, and submission of experimental report templates.
