An assembly method of the b-axis turntable of the end gear plate of a horizontal machining center

Abstract

The invention discloses an assembling method for an end-toothed disc B shaft rotary table of a horizontal machining center. Before assembling, an assembling process scheme is made specific to the failure modes and failure reasons of the end-toothed disc B shaft rotary table. The failure modes and failure reasons of the end-toothed disc B shaft rotary table are determined through the following steps that A, A1-level function analysis is carried out according to the functions and motions of the rotary table, and first-level function motions of the rotary table and corresponding function requirements are determined; B, A2-level function analysis is carried out on each first-level function motions of the rotary table, and second-level function motions of the rotary table and corresponding function requirements are obtained; and C, failure analysis is carried out on all the second-level function motions of the rotary table and the corresponding function requirements, and the potential failure modes and failure reasons of the rotary table are obtained. The assembling method for the end-toothed disc B shaft rotary table of the horizontal machining center has the advantages of improving the reliability of the end-toothed disc B shaft rotary table, lowering the early-period failure rate of a lathe, improving production efficiency and quality of products, lowering the cost in the whole service life of the products and shortening the time.

Description

Technical field [0001] The invention relates to the field of machine tool assembly, in particular to a method for assembling a B-axis turntable of an end gear plate of a horizontal machining center. Background technique [0002] According to the national standard GB-6583, reliability is defined as "the ability of a product to complete a specified function under specified conditions and within a specified time." It can be seen that when the product cannot meet the specified function or does not meet the specified function, reliability Sex cannot be guaranteed. A good assembly process plan can not only improve the production efficiency and quality of the product, but also reduce the cost and time of the product's entire life cycle process. Therefore, in today's diversified product and customer needs, the optimization and improvement of the assembly process plan is of great importance. . In order to improve product reliability, domestic manufacturers (especially high-end CNC machi...

Problems solved by technology

The assembly process plan is very important to the design and manufacture of the product. There are many researches on the process plan at home and abroad, such as "Research on the Green Product Manufacturing Process Plan" by Cao Jie and Yi Hong ("Journal of Mechanical Engineering" 2002 No. 7 ) made a decision-making optimization for the process scheme of green manufacturing; Liu Xiaobing, Yang Jingping, Ma Yue's "Incremental Design Method for Multi-process Scheme of Special Steel Products Based on Quality Function Deployment" ("Computer Integrated Manufacturing System", Volume 15, No. 1, 2009 In the previous period), the house-of-quality model of incremental design of multi-process schemes for special steel products was established; however, these studies basically did not consider reliability factors
