【摘要】：近年来我国机械制造加工业飞速迅猛的发展对我国的机制机加行业,尤其是对机加加工的质量提出了越来越高的要求.打壳机气缸内孔加工质量要求高,刚度极低,生产技术难度大,通过设计专用加工装置较好的解决了这一问题.专门为打壳机气缸内孔加工装置做了一次设计,利用普通车床加工出满足相关表面要求的内孔.介绍了深孔加工发展历程,对打壳机气缸缸体进行了加工工艺的分析,根据工件工艺规程需要,设计了镗缸体内孔所需的加工装置;对加工装置进行了结构设计,采用了前后倒顶尖的装卡结构和定位方式,定心效果良好,避免了装卡变形;镗头部位还加了支撑,刀杆内部做了两条通道以便通切削液和压缩空气以解决了深孔加工的排屑、导向、冷却的三大问题;并对加工装置中主要零件镗杆进行了受力分析,并对镗杆进行稳定性计算.这样的加工装置不仅保证了相关技术与要求,还使得其可轻而易举的在车床上完成.
[Abstract]:In recent years, the rapid development of China's machinery manufacturing and processing industry has put forward more and more high requirements for the machinery processing industry, especially for the quality of mechanical processing. The machining quality of cylinder bore is high, the rigidity is very low, and the production technology is very difficult. This problem is solved by designing a special machining device. A special design is made for the inner hole machining device of the cylinder of the hulling machine, and the inner hole which meets the requirements of the related surface is machined by the common lathe. This paper introduces the development course of deep hole machining, analyzes the machining technology of cylinder block of shell punching machine, designs the machining device needed for boring the inner hole of cylinder block according to the requirements of workpiece process rules, and designs the structure of the machining device. Adopting the front and rear center loading structure and positioning mode, the centering effect is good, and the clamping deformation is avoided; the boring head position is also supported, and two channels are made inside the tool rod to pass through the cutting fluid and compressed air to solve the chip removal from deep hole machining. This paper analyzes the force of the boring bar of the main parts of the machining device and calculates the stability of the boring bar. Such a processing device not only ensures the relevant technology and requirements, but also makes it easy to complete on the lathe.
