自动数控它的作用是进行各种性质不同的钢材板材磨削,主要应用于钢材、铝箔和造纸行业等。然而其在磨削工作辊的过程中,两端的轴承箱体会与砂轮架发生干涉,而频繁的装卸轴承箱体则会使加工过程变得繁琐,因此设计了翻箱机构,将工件翻转90度。设计翻箱机构,包括翻箱机构的工作原理、机床各部件的组成、其操作要求和方法以及翻箱机构技术要求进行了概述,并详细设计了MKZ84125轧辊磨床的翻箱机构,其中包括法案的选择,电机的确定以及蜗轮蜗杆与各个轴以及齿轮的选择并画出了机床总装图,翻箱机构总装配图以及部分重要零件的部件图。其设计过程主要特点是采用三相异步电动机带动蜗轮蜗杆以及齿轮传动,以达到将工件翻转90度的效果,方便磨床加工。翻箱机构结构简单紧凑,操作简单,维护方便,翻转工件效率高。

Abstract
The C grinding machine is an important corollary equipment which rolls production line by steel and sheet metals. Its grinding accuracy and efficiency directly affect the quality of steel rolling and its production efficiency. Its role is to grind the various properties of steel and sheet metals, it mainly used in steel, aluminum foil, paper industry and etc. However, during the process of grinding, the bearing boxes of both sides will interfere with the wheel frame, and loading and unloading the bearing boxes frequently will make the process plicated, so I designed the box turnover mechanism, it can let the workpiece rotate 90 degrees. Designing the box turnover mechanism, it consists of its working principle, position of each part of machine tool, its operating requirements and methods and providing an overview of technical requirements of the box turnover mechanism. What
’s more, I also designed the box turnover mechanism of MKZ84125 rolling grinder. It involves the choice of the Act, the determination of motors and the selection of worms, each shaft and gears. In addition, I draw the assembly chart of machine, the general assembly chart of the box turnover mechanism and the parts diagram of some important parts. The main features of designing process are adopting the three-phase asynchronous motor to drive the worms and using the two-stage gears to drive to reach the effect which let the workpiece rotate 90 degrees. It will convenient the process. The structure of the box turnover mechanism is simple pact. It can operate simply, maintain easily and the workpiece is efficient.
