Analysis of the structure, size, and moment of inertia of the fixture assembly is one of the essential aspects of the overall design. In the traditional design process, this process is generally calculated by hand. Most of the cases rely on experience to make the accuracy difficult to guarantee and increase the difficulty of the overall design. Application of Pro/E software makes assembly gap adjustment and assembly interference inspection more accurate, intuitive and fast. Moreover, for areas where the inspection equipment is not accessible, the gap can also be controlled, so that the interference problem is eliminated at the solution stage.
In the first step, the material density is given in the prompt line of the menu [Model] → [Part] → [Setup] → [Densit.], and the quality is defined under the menu [Model] → [Part] → [Setup] → [Units]. , length unit.
In the second step, enter the [Analysis] main menu to analyze the distance, model, curve, surface, etc. in real time.
Replacing unreasonable components and modifying unreasonable positions, the full correlation of Pro/E can change the size, size and specifications of the components slightly, and the assembly will change accordingly to meet the design requirements.
2.4 Information Processing
The processing of related information includes the generation of assembly drawings and explosion maps and the extraction of schedules.
(1) Generation of assembly drawings and explosion maps
Pro/E has robust assembly drawing capabilities. After the combined fixture simulation assembly is implemented in 3D space, a command can be specified on the menu to quickly create a 2D assembly drawing. If the basic view or the view cannot clearly express the more complex assembly relationship, make the necessary sections and select these sections for partial enlargement, rotation, and expansion. For the 3D assembly model, it can be used as a stand-alone view, scaled and placed in the upper right corner of the drawing to improve the reading speed of the engineers. This saves time for proofreading, reviewing, and approving personnel's drawings, and allows them to devote more effort to functional review.
(2) Extraction of schedules
After the view is completed, the Pro/E platform can automatically complete the statistics of the part quantity and the filling of the detailed list. In the traditional combined fixture design, the information statistics of the combined components consume a lot of time from the fixture technician. And energy. In the main menu [Info] list, you can display the characteristic information, all the components of the assembly model, the feature master-slave relationship, and the model size. For example, [Info] → [Model] → [Top] → [Leve] → [Apply] can list the assembly sequence, master-slave relationship, basic size, etc., establish a basic information list, the craftsman can edit the schedule, for the assembler Provide assembly basis to make actual assembly more organized. Finally, the assembly workers rely on the established 3D assembly model, explosion map, 2D view, and information schedule for actual assembly.
3 Conclusion
The Pro/E software is used to create a library of standard fixtures. The designer can quickly simulate the assembly by selecting the standard components, and adjust the changes to the unreasonable assembly structure. With the development of robots, the actual assembly of the combined fixtures tends to be more automated. After the assembly is completed by Pro/E design, the assembly information is controlled to automatically assemble the robots, which can minimize the workload of the workers and make the assembly technology more suitable. The need for modern manufacturing. Pro/E's intelligent 3D software facilitates the design of combined fixtures and makes assembly fixtures more suitable for flexible manufacturing systems.
