Abstract


  In this paper, the design of the fork processing speed, design, calculation and design of drilling jig. Fork the surface of the choice of processing methods, processing sequence of the arrangement, process centralization and decentralization of treatment, the division stage of processing, machine tools and process equipment selection, allowance and processes determine the size and tolerance of the preparation process are the main point of order problem. Fixture Design and facing the program is designed to identify, locate component selection, positioning errors of analysis and calculation, the calculation of clamping force, the specific folder structure and the rough with the determination of fixture elements. There are fork blank map, fixture assembly parts diagram and mapping how to ensure the technical conditions fork is the most important process, and fixture also plays a vital role.

Fork reasonable structural design, design process to ensure quality processing fork, to improve the productivity of great significance, it is to ensure that the key to product quality. Fork through the design process can be found in a product design process requires a good co-ordination to succeed.


Keywords: fork; technology; fixture; clamping; positioning
