Opening report of three-dimensional modeling design of vice based on proe Part II: 1. The basis and significance of the topic selection.

The electric vise used by locksmiths is rare in the market now. First, according to the higher and higher production technology, the higher the production precision, the more precise the production, and the more accurate the clamping force, neither too large nor too small. However, the clamping force produced by the traditional vice is guaranteed by the master's manager, so it is very likely that the above shortcomings will occur and the rejection rate will increase. According to the needs of production, a set of electric vice suitable for fitters is designed. Second, the efficiency of traditional vice is relatively low. The traditional vice is driven by thread, which can't realize fast clamping and loosening, and the production efficiency is relatively low. The existing electric bench vise is basically used on lathe, which can realize rapid clamping and loosening, but it is not suitable for being equipped with electric power source, and the cost is too high if it is used on fitters. The newly designed electric vise for locksmiths can not only realize fast clamping and loosening, but also the power source of the electric system is manual, so the cost is lower than that of the vice for machine tools, only not much higher than that of the traditional vice. The electric vice for locksmith has the above advantages, and it is only a matter of time before the new vice comes out, which is an inevitable trend.

Second, the introduction of relevant research at home and abroad (description)

At present, many domestic scientific research institutes have done or are doing research on the secondary development of CAD systems using Pro/ENGINEER, but there are many mechanical designs for these systems. Hefei University of Technology has conducted research on the development technology and practice of Pro/ENGINEER customized menu, that is, how to add customized menu to Pro/ENGINEER; Through the secondary development of Pro/ENGINEER, Hefei University of Economics and Technology put forward a method of feature modeling using engineering database. Chenchen of Nanjing University of Aeronautics and Astronautics participated in the development of a relatively complete system for shaft parts design (three-dimensional model), parts drawing and parts processing (tool path code generation), so that some general design processes can be handled automatically and the workload of designers can be reduced. The Institute of Mechanical and Electrical Engineering of North Jiaotong University is engaged in the research on the establishment of 3D standard parts library of diesel locomotive based on Pro/ENGINEER. Based on Pro/ENGINEER, this system uses its powerful parametric modeling technology and secondary development module Pro/TOOLKIT to establish a three-dimensional standard parts library for diesel locomotives, so as to adapt to the design and development of new locomotive products and improve the practicability of Pro/ENGINEER system. CIMS Center of Tsinghua University Precision Instrument Department proposed to develop a concurrent engineering CAD system based on Pro/ENGINEER system.

Abroad, Wynne Hsu of the National University of Singapore and others developed a system combining assembly design analysis with product conceptual design through C language programming based on Pro/E software. The system realizes the automatic assembly of products by designing five modules: feature base, analysis module, interaction module, search module and assembly module [9]. Because the research and development of 3D design software abroad has a long history and has been applied to related industries, the independent development technology in its application field has been very mature and perfect.

Third, the research content of this topic.

(1) measure the vise, and reconstruct its model through the three-dimensional drawing software Pro/E.

(2) After surveying and mapping the product, use Pro/E to reconstruct the three-dimensional model of the product vice according to each size.

Fourthly, the research method of this topic.

Using ProE, the three-dimensional model of vice parts drawing is established, and virtual assembly, interference detection and system optimization are carried out.

Verb (abbreviation of verb) research goal, main characteristics (innovation) and work progress

Using the parametric function of Pro/E software or instruction programming technology, the standard parts library commonly used in our unit is established.

Reduce repeated modeling time and improve design efficiency.
