Forklift frame multi-dimensional CNC preset

Pro/E secondary development follows the above-mentioned gantry design calculation process, through the Pro/TOOLKIT secondary development method provided by Pro/E, using its rich underlying resource graphics data operation library function, using VC++ program development tools and MFC programming In this way, the specific graphic processing and calculation analysis method of the forklift frame is integrated into a separate program module, and a special forklift gantry design pull-down function menu is added to the Pro/E main interface to realize the key design variable input and output dialog window control. The digital application technology for visualizing human-computer interaction processes. This results in a professional design software that is simple to operate and user-friendly.

Basic Ideas Pro/TOOLKIT secondary development is based on programming on the feature database, and each feature corresponds to an element tree. The element tree defines the type of the feature, reference information, sketch section, size information, positional relationship and other attributes. It is not only a heavy workload but also a difficult task to completely construct a three-dimensional model by programming geometric features. Therefore, it is generally necessary to first create a three-dimensional model of the entity as a template, and then perform read and write access to the feature library that is formed, deleted, modified, and the like. To get new models that meet user requirements. Therefore, the basic idea of ​​this paper is to establish a three-dimensional structural entity model of the gantry with the support of Pro/E interactive graphics system, and rely on the function function of VC++ program development system and Pro/TOOLKIT to realize the operation of the gantry structure characteristic database. Develop a digital virtual manufacturing system for gantry systems that integrates digital design, component assembly, and finite element analysis of structural strength and stiffness.

Feature Modeling A feature in product design refers to a set of primitives with a specific meaning that represent a certain geometric configuration of the product. According to the way of forming the entity, the positional relationship, etc., it is usually divided into basic physical features formed by stretching, rotation and scanning. Based on the attachment features such as holes, chamfers, ribs, etc. on the entity and the symmetry of the entity, the features are edited by the features of the elements copied, mirrored, and arrayed, and the reference features reflecting the position of the primitives. Establish parent-child associations for features. A three-dimensional solid model is organized by a large number of features in the form of building blocks. Therefore, the feature is the basic unit of the model. The process of creating the model is the process of adding various feature tuples in a certain order. This idea of ​​feature modeling provides great convenience for manipulating and managing primitives of the entity structure.

Since the inner and outer gantry, fork frame, fork, lifting and tilting cylinder of the forklift are all arranged according to their vertical center plane, the modeling needs to be combined with the analysis of the demand for programming control. Make full use of these characteristics to plan the dimensional relationship chain of component dependencies, so that the model after the design change can always maintain consistency. This can better reduce the difficulty of programming and improve the quality of program operation.
