Title The Design and Analysis about Automatic Bullet Puller System
Abstract
Based on the understanding of the traditional bullet puller, this article offered an independent design of the "automatic bullet puller system". This article described the overall design of the system which is determined with the instructor repeatedly demonstrated, it analyzed the functional requirements of the system and presented a overall structure framework of design scheme.
The system include four parts: transmission system, sensor system, mechanical drawing system and control system : transmission system mainly use the bullet sleeve to fix the substrate and air cylinder, it finished the bullet transmission through air cylinder’s telescope. When the warhead separation is accomplished then spout to complete the work that transfer warheads. Mechanical drawing system consists of bullet shells sleeve, clamping spring rod ,drive cylinders and other components. Sensing system consists of the grating displacement sensor of transfer cylinder installed in the bottom and the pressure sensor on the spring rod and the grating displacement sensor. Control system through the communication between PC and PLC, the manipulation can pull bullet by remote operation monitoring system, it can reduce the intensity of labor in traditional job of pulling bullets and improve the degree of security and automation.At the end of this article,the simulation analysis was carried out on the system.
