The modular machine tool design for half finished and finished boring of cylinder cap pipe hole (jig design)
Abstract: The modular machine-tool is defined as half finish and full finish boring machine with cylinder lids. In addition to the accomplishment of “Three drawings and one card”, the major task is to finish the design of jigs. The project originally from Jiangsu Gaojing Mechanical & Electrical Equipment CO.,LTD. Ltd aims to cater to the assembly line and improve effectiveness and processing precision so as to reduce the cost. During the process of design, I drew lessons from international and national data, and referenced some literature material related to the topic.
The designs cover the overall ones of the assembled machine and jigs. Firstly, as far as jig design, the main part of the designs, is concerned, the original machine tool has characteristic of multi working procedure machining, effectiveness, difficult machining size guarantee, and low location precision. After being improved, both the air inlet louver and outlet louver are bored by jigging just once, which not only improves effectiveness but also guarantees machining hole sizes. Next, in order to ensure the process precision and production efficiency of boring machine tool ,the jig uses ‘one surface-two sell’ .the way of Clamps is hydraulic pressure clamping, which replaced by Manual clamping. It can enhanced the work efficiency. At last, carry on the computation, the analysis, the examination to corresponding parts.
