自動上料系統(tǒng)設計——夾具設計

摘    要
   
    隨著生產(chǎn)力的發(fā)展，用于傳統(tǒng)機械加工中的手工上料已經(jīng)不能滿足現(xiàn)有生產(chǎn)效率的要求。對于一些加工行業(yè)，其勞動強度大而且危險，很需要把人從中解脫出來。伴隨著技術(shù)的發(fā)展和追求工作環(huán)境的人性化，自動上料系統(tǒng)應運而生。
自動上料系統(tǒng)是傳統(tǒng)的機構(gòu)學與現(xiàn)代電子自動化技術(shù)相結(jié)合的產(chǎn)物，是計算機科學、控制論、機械學、電子技術(shù)等多學科綜合性的高科技產(chǎn)物，是典型的機電一體化產(chǎn)品。它是一種仿人操作，可使用于各種復雜環(huán)境。自動上料系統(tǒng)的出現(xiàn)和發(fā)展，不但可以部分取代人完成各種惡劣環(huán)境下的工作，而且將對人類社會產(chǎn)生深遠的影響。
本文首先介紹了國內(nèi)外自動上料系統(tǒng)研究現(xiàn)狀，闡明了本課題研究的目的、意義。本文針對一種端塞小孔加工自動化的要求和特點，提出了一種由振動盤、上料道、加工裝置、檢測裝置和卸料道組成的自動上料系統(tǒng)。振動盤用于對所要加工的工件進行排序；上料道用于運送排序好的工件到達指定位置；加工裝置用于加工工件；檢測裝置用于檢測加工好的工件是否達到加工要求；卸料道用于運送加工好的工件到達指定位置。本文重點介紹加工裝置中夾具的設計。

ABSTRACT

With the developing of productivity, hand-feeding used in traditional mechanical processing can not meet the requirements of the productivity. For some processing industries, it is not only labour-intensive but also dangerous, and it is necessary to extricate the people from them. Along with the technology developing and the pursuit of the humane work environment, automatic feeding system emerges as the times require.
Automatic feeding system is a product of traditional mechanism and modern electronic automatization technology, and it is a synthetic high technology result of many subjects such as computer science, cybernetics, mechanics, information science and electronic. It is a typical product of mechanics. It is the automatic equipment which can imitate the action of mankind, it is precise and suitable for many kinds of complicated environment. The appearance and development of the automatic feeding system will not only replace man to do works that under terrible conditions, but also bring profound influence to the life of human society.
The article first introduces the domestic and overseas research situation of automatic feeding system, and expounded this articles’ research goal and the significance. For the cypriot-hole automated processing requirement and characteristic, we present the automatic feeding system with a vibrating tooling plate, feeding road, processing devices, detection devices and extraction road in this paper. The vibrating tooling plate is to be used in orienting the components; feeding road is used to transport the components arrived at the designated location; processing devices is used to process the components; detection devices is used to detect whether the processed components achieved processing requirements and extraction road is used to transport processed components arrived at the designated location. This article focuses on clamp belongs to processing devices.

Key words: automatic feeding, vibrating tooling plate, clamp
