Abstract
This paper introduces the design of the box joint part of carding machine drill combination machine，which is widely used for its high efficiency. This design task includes five parts: working out processing technology of joint part of carding machine, design and assemble of drilling jig, design and assemble of main spindle box, design hydraulic control parts, design combination machine tool.
During process planning, define the productive process of joint part of carding machine and find out the best process plan by analyzing production lot, which show process planning is very important in product process; this paper introduces experiences of attachment design by using a practical example．It focuses on discussing how to improve the precision of hole position; using two sides bore modular machine tool as an object, according to the basic principle of the hydraulic system design, formulates the reasonable schematic diagram, the hydraulic pressure part specification through computation of the system main parameters is determined; Some designing examples are analyzed in this paper, and the considerations are discussed for designing compo site tools for machining holes during designing combination machine tool, such as general parts’ (hydraulic slippery platform, driving force box, etc) selection and special use components’ (main spindle box) design .
Key words: combination machine tool hydraulic transmission axle boxes handicraft drills clamp
