What are the main components of the power head?

The power head can realize the main movement and feed movement: the power part can realize the automatic cycle of the workpiece. A relatively simple variable speed transmission mechanism, a variety of forms, the basic principle is driven by the motor a variable speed mechanism, can achieve media cutting, milling, drilling and other functions: some with guide rail, can carry out a small range of linear motion. How many parts must it consist of?"

Important components of the power head: 1 main motion, 2 feed motion, 3 control system, 4 mechanical structure characteristics

1. The main motion of the electropneumatic automatic feed drilling power head is driven by three-phase asynchronous electricity, and the motor torque is transmitted to the spindle through the synchronous gear belt and spline oil. Different synchronous gear belts can achieve different shaft speeds because the main movement of the power head is driven by the motor: the source characteristics of the main workshop are good, the output power and torque are large, and the processing conditions of multiple auxiliary drilling and large aperture can be adapted.

2. Because the pneumatic transmission has the advantages of action reaction block, good adaptability to the environment, simple structure, small size, stepless speed regulation, long working life, convenient power source, etc. : Therefore, the feed movement of the power head adopts compressed air as the power source: Considering the compressibility of the air, the power head movement is not smooth when the load changes, the hydraulic governor is used to realize the alarm and control of the working speed, and the exhaust throttle valve regulates the fast connection and backward speed of the power head respectively.
