ABSTRACT
c feeds systemThis thesis mainly illustrates the improving and design of Bench-type drilling machine. We change the Bench-type drilling machine to automatic drilling machine by transmitting into hydraulic system and PLC control system, the automatic drilling machine can be controlled by PLC.
We ascertain the entire scheme by the general machine design steps in the design process, and then separately design the feed system、drives system and control system.
The purpose of this design as below: By transmitting into hydraulic system and PLC control system, the automatic drilling machine c the system of the automatic drilling machine can work reposefully and satisfy the require; the spent of design is economic.
The important parts of the thesis are the design of hydraulic feeds system and PLC control system. The design of feed hydraulic system includes the designs of hydraulic tanks structure and control; the design of PLC control system is choosing the electrical components and programming control program to controlling the automatic drilling machine according to the requirements of work and control.
The Bench-type drilling machine improved can be controlled automatically. It is a typical machine of Mechatronics.
Key words: automatic drilling machine; hydrauli; PLC
