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
Key words：Lock ring; Trimmer; Jig; Transmission
