3D Modeling and Assembly of the Crushing Machine

This article will explore the 3D modeling and assembly of the crushing machine. Let’s take the jaw crusher for an example to analyze the overall structure. The jaw crusher is composed of the frame, movable jaw parts, adjustment parts, transmission parts, taut parts, lubrication components and others. We should achieve the 3D modeling and assembly in accordance with the design requirements for the crusher. The rack is basically composed by the welded steel plate, but the characteristics are many and the shape is complex. When we use the 3D design software for the modeling and assembly, there will be too much work if those welded steel plates are directly built as a single part in the part environment. It is easy to cause the errors and the maintenance is difficult. As a result, we should first create model for the simple steel plate. Then we can assemble the welded parts to the form of assembly.
The key technologies and techniques for the modeling and assembly of the crusher are summarized as follows.
First, you should first create the matrix for the three-dimensional modeling of the parts. Then you can build the rest of the features on the substrate. Based on this, you should classify the parts first of all. The crushing parts are mainly divided into plate parts, cylinder parts and others. The welded steel plate in the rack and the jaw plate are composed by the plate parts. There are many cylinder parts in the movable jaw parts. In most cases, the matrix of the plate parts is created by the extrude feature. The matrix of the cylinder parts matrix is created by using the rotate or stretch characteristics. Of course, this is not stereotyped. We should combine with the specific situations. The scanning and lofting features can be used in the matrix of the parts.
Second, the 3D design software is based on the sketch. In terms of the feature-based 3D design software, the quality of the sketch determines the quality of the part model. Sketches include the geometry and dimensions, geometric constraints. The sketch of crusher parts has completely right geometry.
Third, the overall structure of the crusher is basically symmetrical, so reasonably solving the symmetrical features and parts can improve design efficiency and save time, which also has a vital role for the overall assembly of the crusher and analysis. The parts with symmetrical structure can achieve the direct creation of the symmetrical sketch and can create a half model to achieve this by using the environmental characteristics.
