Dovetail groove type slipway cylinder intelligent control system for manufacturing surge protector Technical Field The invention relates to the technical field of control of fluid pressure systems, in particular to an intelligent control system of a dovetail groove type sliding table cylinder for manufacturing a surge protector. Background The dovetail groove type sliding table cylinder is used as an integrated linear motion unit and is widely applied to the occasions such as positioning, transferring and assembling of the surge protector in the surge protector manufacturing equipment. The cylinder and the precise guide rail are compactly combined together, and the reciprocating linear motion is realized by driving the sliding table through compressed air. In the application scenario of vertical or inclined installation, the slipway and the load carried by the slipway are subjected to the action of gravity, once an air source is interrupted or a control system fails, the slipway has the risk of falling down at stall, equipment damage or safety accidents can be caused, and therefore, the equipment of the effective anti-falling mechanism is important. In the prior art, for the fall protection of such cylinders, solutions of purely mechanical or pneumatic locking are generally adopted. The mechanical scheme is mainly that when power or air is cut off, a guide rail is clamped by a brake pad or a wedge block driven by spring force, so that passive braking is realized. The pneumatic locking scheme is characterized in that a pilot operated one-way valve is additionally arranged in a gas path of the cylinder, gas in the working chamber is sealed when the position needs to be kept, and the load is balanced by using the pressure of the gas. These approaches all trigger execution upon detection of an explicit fault signal. However, the triggering of the mechanical braking device has hysteresis, and the braking process is very rigid and intense, the generated impact and vibration are large, and the sliding table or the precise workpiece carried by the sliding table is easy to damage. The pneumatic locking mode has the problem that the position moves downwards slowly due to gas leakage, the locking force is greatly influenced by the pneumatic fluctuation, and the locking reliability is difficult to ensure when the load changes or external impact is applied. More importantly, the schemes are passive response type, can only remedy after the fault occurs, cannot foresee risks and intervene in advance, and lack dynamic adaptability to the running state of the system.
