橡膠成形件自動修剪機夾具及傳動部分的設(shè)計
摘要：隨著橡膠密封圈的大批量生產(chǎn)，對橡膠成形件自動修剪機的需求也跟著擴大。因而對加工效率提出很高的要求，全自動橡膠修剪機就是為滿足市場需求而設(shè)計的。本課題是橡膠成形件自動修剪機夾具及傳動部分的設(shè)計，包括機械手的設(shè)計，自動上料、下料機構(gòu)設(shè)計，自動切削部分設(shè)計。在夾具部分設(shè)計中，分析了兩種方案，一種是采用機械夾緊方法，另一種是采用氣體負(fù)壓夾緊?？紤]多種因素采用了氣體負(fù)壓夾緊。夾具設(shè)計合理，精度合適。在傳動部分，傳動方式采用了帶傳動，方案結(jié)構(gòu)簡單，成本低。在機械手的設(shè)計過程中分析到機械手末端兩種方式，采用了一個氣爪一個電磁鐵的方案。在傳感器的設(shè)計部分中，采用了光電傳感器和電磁式傳感器。本課題設(shè)計的夾具及傳動部分，方案合理，結(jié)構(gòu)緊湊。完成了自動修剪機夾具及傳動部分設(shè)計指標(biāo)要求。設(shè)計的機器能夠完成切削范圍：?20—?50，切削效率：15-20個/分鐘。這種橡膠成形件自動修剪機的大量生產(chǎn)，能夠提高加工效率，增加利潤。

The jig and transmission part designs of rubber forming automatical trimmer machine
Abstract：With the mass production of rubber lock ring,the demands of rubber forming automatic trimmer is growing rapidly. High requests are proposed to the processing efficiency , the automatic rubber forming trimmer is designed to satisfy the demands of the market. This topic is about the design of the jig and the transmission part of rubber forming automatic trimmer including the design of mechanic hands, the automatic material loading and discharging parts and design of automatic cutting parts, In the design of jig part,two kind of plans has been analyzed , one is mechanic clamping, the other kind is gas negative pressure clamping . The design of the jig is reasonable, the precision is appropriate. In the transmission part, the belt transmission is adopted ,the structure is simple, the cost is low. The terminal two ways in mechanic hands design process is analyed, a gas fingernail electro-magnet plan is adopted. In the part of sensor design, the electro-optical sensor and the electro-magnetic sensor are adopted. The design of jig and the transmission part is reasonable,the structure is compact. the design target t of the jig and the transmission part of automatic trimmer is attained The machine designed can satisfy the cutting scope: ?20-?50, cutting efficiency: 15-20/Minute, Once this kind of rubber forming automatic cropper is massly produced, it can enhance the processing efficiency of enterprise and the enterprise profit is increased
