Design of PLC control system for Hydraulic Power Sliding Table


ABSTRACT

Hydraulic Power Sliding Table is a combination of tools used to achieve the feed movement of the general components, hydraulic power slide in the modular machine tool has been widely used. Hydraulic Power Sliding Table by hydraulic variable speed drive system can be easily carried her, positive and negative to stable, the impact force is small, easy to work frequently change. Configuration corresponding power head, spindle and tool box on the workpiece can be completed after the processing of various holes, face processing and other processes, its performance is directly related to the merits of quality machine tools.
The design is a full analysis of the hydraulic power transmission and hydraulic slide sets based on the principle, by a contactor control relay and PLC control program for comparison I chose the PLC control and PLC based control requirements of the model chosen, In the hardware design to draw the external wiring diagram of PLC; in software design, the design of the Hydraulic Power Sliding Table PLC control software flow chart and ladder, to achieve the control requirements.

KEY WORDS: Hydraulic, Power Sliding Table，PLC，control

Hydraulic and pneumatic transmission

1.1 Characteristics of hydraulic and pneumatic power

1.1.1 A hydraulic drive with the following advantages
1. In the same volume, the hydraulic unit higher than the power generated electrical installations. Under the same power, the hydraulic device small size, light weight, power density, compact structure. Hydraulic motor the same size and weight of only about 12% motor power.
2. Hydraulic equipment work stable. As the light weight, inertia, fast response, easy to implement quick start of hydraulic equipment, braking and frequent commutation.
3. hydraulic device can be realized in a wide range of variable speed (variable speed range up to 2000), it can be carried out during operation speed.
4. hydraulic drive is easy to automate, its fluid pressure, flow, or flow direction is easy to adjust or control. When the hydraulic control and electric control, electronic control, or used in conjunction with pneumatic control, the entire drive unit to achieve a complex sequence of actions can be easily remote controlled.
5. hydraulic overload protection d..
