内容简介：

摘 要本文介绍了一种新型的压力机与垫板间快速夹紧装置。分析了该装置的工作原理和液压控制原理和电器控制原理。在现代化的生产实际中，压力机与垫板之间的夹紧装置还是传统的手动夹紧装置。不仅耗时费力，而且已经远远不能满足现代化生产的需要，因而急需对其进行改造。压力机与垫板间的快速夹紧设计就是应现代化生产的需要而研究设计的。该设计包括机械夹紧装置的设计，液压控制系统的设计，以及电气控制系统的设计。将机电液技术结合起来，实现快速夹紧。压力机与垫板间快速夹紧装置主要由机械夹紧装置、液压控制系统、电气控制系统组成。它以机械夹紧装置为主要的夹紧执行元件。通过螺杆与螺母之间的螺旋传动实现夹紧、放松操作，并要求螺杆自锁。液压缸活塞杆的伸缩，使机械夹紧装置摆动，实现抽出垫板的目的。液压缸、液压马达的动作控制由液压系统实现。在液压系统中，采用了电磁换向阀和压力继电器。电磁换向阀和压力继电器的控制，由电气控制系统实现。在电气部分，采用了PLC控制，这样，整个装置的控制可靠性提高，通用性更好，操作更方便。本设计融合了机-电-液一体化的设计理念，寻求更为有效的设计理论和方法来实现压力机与垫板的快速夹紧。该夹紧装置实现了设计目标，具有较高的自动化程度，运行稳定可靠，性能价格比较高，非常适合于现代化生产实际的需要。因此，该产品的推广具有十分广阔的前景。关键词：夹紧装置；液压系统；电气控制；机电一体化。Design of The Clamping Device Between The Press and Backing BoardAbstractThis paper introduces a new type of fast clamping device between the press and the space block. It also analyzes the working principle and the hydraulic and the electrical principle for this kind of trigger equipment.At present, in the practice of the moderation production, the clamping device between the press and the space block is still controlled by handed clamping equipment, it not only costs much time and labour power, but also can not meet the need of moderation production. For these reasons, the traditional handed clamping should be improved.The design of a new type of fast clamping device between the press and the space block is based the need of moderation production. It consists three parts, which are machinery clamping equipment, the design of hydraulic control system and the design of the electrical controlling. The integration of the machinery, electricity and hydraulic pressure brings about fast clamping device.There are three important parts: the fast clamping device, the hydraulic controlling system and the electrical controlling system. The machinery fast clamping is the most important clamping actuating mechanism. Through the spiral movement between the clamping device, the lead-screw and the nut, it realizes the clamping movement and disengagement , it also must has self locking.The shank of the piston of the hydraulic presser has the movement of elongation and drawing back, in this way, we can realize oscillatory movement of the machinery, and get out the space block. The movement of the hydraulic presser and the hydraulic motor is controlled by the hydraulic control system. In the hydraulic system, the controlling of the solenoid operated direction vale and the pressure switch is realized by the electric automation.The application of the PLC improves the reliability of the whole set, and makes the compatibility better and the controlling of the set much convenient.This design consists the theory of the mechatronics, we want to find a much better designing theory and method to realize the fast clamping between the press and the space block. This fast clamping device brings about the target of this design, it has a high level of the automation and the operating is reliable. And what is more, the performance index is high. This device is much suited t
