底片自动取送机械系统设计
摘 要
随着科技的发展，高能射线探测被广泛的应用到固体火箭发动机的质量检测中。在这个探测过程中，空气会被电离产生大量的臭氧气体。过量的臭氧气体对人体有很大的伤害，所以人不能过早的进入检测实验室中去取换接收检测信息的底片，这势必会影响工作效率。为了提高工作效率，取送接受检测信息底片的工作必须由机械系统自动完成。
本设计就是针对这种需求所进行的。该系统可以在有大量臭氧存在的环境下自动夹取、运送底片，不需要等到臭氧从检测室排除，所以大大地提高了工作效率。

Film-catching-and-delivering system design
Abstract
With the development of technology, the hign-energy-radial fault detection method has been largely used in the quantity examination for the solid rocket engine. However, in the detective process, mass of ozone gas might be generated by radial, excessive quantity of which means great harm to the people around. For sake of this, people are constrained from going into the room to get information films too early, and this will greatly reduce the work efficiency. In a word, in order to improve the work efficiency, catching and carrying the films should be completed by mechanical systems automatically.
This design aims to meet this requirement. The system can catch and carry the film automatically in the environment of mass of ozone. So it improves the work efficiency greatly . The mechanical structure of this system can be divided into two parts, the upside part as carrying department and the underside as automatic catching department. Of them , the motor drives two active wheels through the decelerating system. Then, the active wheel pull the whole system to move forward or backward on the preconcerted tramroad. The automatic catching department can safely realize catching film and it is composed of two special holding structure jointed by one mechanical arm, it can catch the film safely. The catching department is a new combination of the mechanism and electron equipments, it realizes the catching and loading action by the contraction and extension of the electromagnets. So it can catch and load the film very fast and frequently.
