Dyjx-TL camskin mechanism movement and test analysis training device

In modern " Mechanical Principles " teaching, more and more attention is p*d to teaching methods that combine theory and practice for students, focusing on cultivating students' hands-on ability and innovative awareness, and focusing on cultivating students' flexible movement abilities for modern virtual design and modern testing methods. . The cam mechanism is a commonly used mechanism in machinery . With the development of modern industry, mechanical automation and semi-automation have become increasingly popular, and the cam mechanism has been more widely used.

Functions and features

(1) The cam motion precision measurement test bench has manual testing and automatic testing functions for convex contours. Learn how to test convex contours through experiments.
(2) It has the function of reverse calculation of the cam profile curve. Based on the detection data of the cam profile and the basic dimensions of the cam mechanism obt*ned by measurement, the computer is used to reversely calculate the numerical function change rules of the follower's displacement, similar velocity and similar acceleration.
(3) Use the computer to collect and process the motion parameters of the follower of the cam mechanism, and make the measured curve of the motion pattern of the follower, and use the computer to numerically simulate the motion of the mechanism to make the corresponding follower response. The theoretical curves of the movement laws of the parts can be used to g*n an in-depth understanding of the motion characteristics of disc cam and cylindrical cam mechanisms with different laws.
(4) Compare the measured results of the cam mechanism motion parameter curve with the theoretical simulation curve, compare the differences between the two, and analyze the causes of the error.
(5) Optimize the design of the cam mechanism structural parameters through computers, and simulate and test the motion of the cam mechanism to achieve an effective combination of computer-*ded design and computer simulation and test analysis, achieve a close combination of theory and practice, and tr*n students practical ability and innovative awareness.
(6) Mechanical assembly and fitter assembly virtual simulation software
sub-module A, using 3D virtual simulation technology and AVI video playback method, the interface is vivid and beautiful, easy to learn and use, which can increase students' interest in learning and deepen students' understanding and application of knowledge. . Through the three-dimensional disassembly and assembly video animation, the disassembly and assembly process of the gearbox, clutch worm transmission mechanism, gear reducer, intermittent rotary table, punch mechanism, power source, feeding mechanism and other modules are vividly displayed. The following functions can be realized: basic knowledge and introduction of fitter assembly technology, structure and working principle of the m*n components of fitter assembly technology, virtual disassembly and assembly of gearbox, three-dimensional animation video explanation and demonstration, virtual disassembly and assembly of clutch worm transmission mechanism, three-dimensional animation Video explanation and demonstration, virtual disassembly and assembly of gear reducer, three-dimensional animation video explanation and demonstration, virtual disassembly and assembly of intermittent rotary table, three-dimensional animation video explanation and demonstration, virtual disassembly and assembly of punch mechanism, three-dimensional animation video explanation and demonstration, virtual power source Disassembly and assembly, three-dimensional animation video explanation and demonstration, virtual disassembly and three-dimensional animation video explanation and demonstration of the feeding mechanism.
Sub-module B, the software is based on C# and JS language programming design. You can choose different interactive interface sizes according to your computer configuration. You can choose six image quality levels such as smooth image quality, medium image quality, and perfect image quality. More than ten types of shafting mechanisms, including gear shafting and worm shafting, can be selected for installation, disassembly, assembly, parts measurement, and assessment. There are intelligent reminders during the steps of parts disassembly and assembly. The models in the software are all 3D models, produced by 3Dmax, and have been rendered and polished to make the models look the same as real parts. There is a non-standard parts library, Standard parts library and measurement tool library for disassembly and assembly selection.
Sub-module C, the system's built-in tool library (such as hammer, wrench, puller, screwdriver, etc.) is used to select tools to disassemble the reducer, and the parts are automatically placed neatly after disassembly.
The software is equipped with integrated electronic experiment assessment questions and instructions for the purpose, steps, and requirements of the experiment. When using the assessment function, the software randomly generates questions for students to answer, and gives assessment scores when students finish answering the questions. The software can rotate, zoom in and out in all directions to view its det*ls.
