5、;　　Abstract</b></p><p>　　This 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 prin

6、ciple for this kind of trigger equipment.</p><p>　　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 e

7、quipment, 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.</p><p>　　The design of

8、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

9、 and the design of the electrical controlling. The integration of the machinery, electricity and hydraulic pressure brings about fast clamping device.</p><p>　　There are three important parts: the fast clamp

10、ing 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,

11、 the lead-screw and the nut, it realizes the clamping movement and disengagement , it also must has self locking.</p><p>　　The shank of the piston of the hydraulic presser has the movement of elongation and

12、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. I

13、n the hydraulic system, the controlling of the solenoid operated direction vale and the pressure switch is realized by the electric automation.</p><p>　　The application of the PLC improves the reliability of

14、 the whole set, and makes the compatibility better and the controlling of the set much convenient.</p><p>　　This design consists the theory of the mechatronics, we want to find a much better designing theory

15、 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 w

16、hat is more, the performance index is high. This device is much suited the need of the modernization production, so it has a broad prospect of promotion.</p><p>　　Key Words: clamping device， hydraulic syste
