What are the main components of a power head?

The power head can realize main movement and feed movement: powered parts can realize automatic circulation of workpieces. A relatively simple variable speed transmission mechanism with various forms. Its basic principle is that a motor drives a variable speed mechanism, which can realize media cutting, milling, drilling and other functions: some have guide rails and can perform small range 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 structural characteristics

1. The main movement of the electro-pneumatic automatic feed drilling power head is driven by three-phase asynchronous electricity, and the torque of the motor is transmitted to the main shaft through the synchronous gear belt and spline oil. Different synchronous gear pulleys can achieve different shaft speeds, because the main movement of the power head is driven by the motor: the main workshop has good source characteristics, large output power and torque, and can adapt to the processing conditions of multi-auxiliary drilling and large hole diameters.

2. Since the pneumatic transmission has the advantages of an action response block, good adaptability to the environment, simple structure, small size, stepless speed regulation, long working life, and convenient power source: Therefore, the feed movement of the power head uses compressed air as the power source: considering the compressibility of air, the movement of the power head is not smooth when the load changes, a hydraulic speed regulator is used to achieve alarm and control of the working speed, and the exhaust throttle valve is adjusted separatelyPower head's fast connection and reverse speed
