Dyjxm series mechanical design teaching experimental device

Release time：2024-05-14 16:00viewed：times

Used for the "Mechanism Movement Simplified Diagram Surveying and Analysis Experiment" in the mechanical principles course. The workpiece is beautiful and elegant, with high precision in finishing and assembly, and the moving components are flexible and free of interference.

M*n technical parameters:
1. Model material: made of aluminum alloy material or real object.
2. The moving components are mechanically finished, with high installation accuracy and flexible movement of the mechanism.
3. The base plates and brackets of each model are p*nted uniformly, and the moving parts are color-coded to make them beautiful and elegant (if there is a base plate).
