Bearing Box Process Specification and Tooling Design

Abstract

Reasonable process regulations and fixtures can ensure the high efficiency of parts processing and the economy of the enterprise. I started with data collection, then part analysis, then process design, then process specification design, and finally fixture design. In the process design, I obtained the best process route based on the experience of the production site to achieve the effect of saving time and increasing labor productivity. The design of the process specification was based on the production program, the production type was determined, and the process specification was compiled. Production, so the process card of parts and the card of machining process of parts were compiled. The fixture design is to design two sets of tools for the bearing box car mold and the bearing box drilling mold. The bearing box car mold is based on the processed large surface and the two right angle surfaces are used as positioning surfaces. The workpiece is fastened with bolts and nuts. The other large surface is up to size 70, φ180H7 holes; the bearing box drilling mold is based on the processed large surface, and is positioned at φ180H7 holes. The workpiece is fastened with bolts and nuts, and 6-φ13 holes are drilled to improve the part. Processing efficiency to ensure the quality of parts processing. In summary, the above-mentioned special fixture design scheme is adopted to ensure the production requirements of parts in batches and improve labor efficiency.
