Aiming at the importance of interface in adaptable design of mechanical products, in this paper, research actuality and development of the Mechanical interface are talked over; and the basic requirements and design criteria of adaptable interface design are discussed; lastly, what capability an adaptive mechanical interface must possess is illustrated combing with a specific case, and the adaptable interface in the case can also be applied to similar structure design of other products.

Aiming at the shaft pressing and assembling process for steel shaft and small gear, which is frequent in toy gear reducer assembling, a reconfigurable and multi-station auto shaft pressing and assembling machine had been developed. In the machine, steel shaft and small gear are positioned in a pre-positioned fixture in advance. The assembling process is carried out in three stations simultaneously. It makes the machines efficiency become higher. Applying the reconfigurable design concept, the machine can be divided into basal modules and changeable modules. The changeable modules can be adjusted or replaced to make the machine fit for components of multifarious small gears and steel shafts with different length and diameter. Each module of the machine is introduced in detail and related problems are discussed in the paper.

The research actuality and development of roller module replacement technology are talked over in this paper. Positioning scheme of one plane and two pins with the special rounded edge diamond pin that is suitable for the longer roller is discussed, which is meeting the parallelism tolerance requirement for the roller within the full length; thus reducing manufacturing tolerance requirement for the spacing between pin axes and reducing manufacturing difficulty. And on this basis, adaptable interface design of roller module rapid replacement system which is suitable for the longer roller has been completed. The invention patent on the roller module rapid replacement system has already been applied for, and the precise positioning of roller module can be realized.

In order to perform adaptability comprehensive evaluation of auto assembly machine product platform for small shaft and sleeve subassemblies, with product family-oriented design, more reasonably and effectively, a fuzzy comprehensive evaluation method based on fuzzy analytic hierarchy process (FAHP) is discussed in this paper. And the hierarchical structure of comprehensive evaluation index system, the alternative set and the comprehensive evaluation model of product platform are established through this method, thus obtaining a satisfaction value, which realizes the change from qualitative evaluation to quantitative evaluation for product platform evaluation. The result shows that the method has a strong feasibility and operability.

By surveying SCARA manipulator in the market, the question that the overall length of arms is fixed, which leads its operating range to be relatively fixed, and the manipulator has badly adaptive can be found. Aiming at the problem, a SCARA manipulator whose arms can be replaced quickly had been designed according to the concept of adaptable design, and the principle of replacement arms had been put forward basing on the analysis to the minimum operating radius of manipulator in this paper. Moreover, an adaptable interface for replacing quickly different grippers during the process of production had been designed in the paper.
