Title The design of the aggregate machine-tool using for processing the screw holes of filter seat of diesel filter
Abstract
The aggregate machine-tool based on common components, together with a small scale of specially designed components, is a kind of machine tool which is designed for processing one or more parts at a predetermined process. In terms of the processing of the screw holes on three directions of filter seat of S195 diesel filter, combined with its technological features, a tapping aggregate machine-tool with horizontal single station on three sides is designed. First, according to the sizes, precision and technical requirements of the screws to be processed, determine the locating datum and clamping points, and develop appropriate technology plan. Select the appropriate cutting parameters based on the material of the part. Secondly, on the basis of the selected process plan, the form of the configuration of the machine is determined. And then the overall design of the machine - three figures and one card is designed. Finally, according to the defined process and structure of the program, combined with process diagrams and machine contact dimension drawings, the spindle box is designed. This design can meet the requirements of the machining accuracy and efficiency.

由于柴油机滤清器滤座零件的结构特点，在螺纹孔的攻制时，普通的机床不能加工这种产品，若分别用三台机床分开加工，其结果就是加工速度慢，操作复杂，并且设备投资也比较大，生产成本也就相对较高。因此,本文根据实际情况，开发了实用的攻丝组合机床。 柴油机滤清器滤座螺孔加工组合机床设计:http://www.youerw.com/jixie/lunwen_2895.html
