Abstract: Power head is an important power of modular machine tool parts. Their quality and performance quality directly affects the whole machine tool performance is good or bad. Among them, the basic structure of pneumatic drill power head is composed of three parts of the main movement, feed motion and control system.

  Along with the large-scale industrial production needs and the rapid development of science and technology, using special equipment assembled into modern high-speed lines and multifunctional and efficient combination machine tools, in many industries has become guarantee the accuracy of product, reduce the production cost, improve labor productivity, and one of the key measures of enterprise competitiveness. Power head is an important power of modular machine tool parts, their quality and performance quality directly affect the whole machine tool performance is good or bad.

  Basic structure of pneumatic drill power head is composed of three parts of the main movement, feed motion and control system. By PURROS Company makes the following details for you.

1, Main movement: pneumatic drilling power head main movement driven by three-phase asynchronous motor, the synchronous cog belt and spline shaft of the motor torque is transmitted to the spindle, does not change with the spindle speed can be made of different synchronous cog belt wheel. Due to the main power head movement driven by motor, spindle speed characteristics, power output and torque is big, can adapt to in multi-axis drilling and large aperture processing conditions.

2, Feed movement: as the pneumatic transmission has quick response, good adaptability to the environment, some advantages such as simple structure, small volume, and can realize stepless speed regulation, long working life, convenient power source, therefore, head of the feed movement using compressed air as power source. Considering the compressibility of air, when the load changes of power head movement stability are poorer, into the speed adjustment and control hydraulic governor is used to realize power head fast rewind and fast forward with the exhaust valve to adjust.

3, Control system: pneumatic type drilling power head the feed movement adopts compressed air as power source, its feed movement control also USES the pneumatic control system, the five ventilation control valve consists of two, two a motorized valve, manual valve, a number of throttle valve and two external control air supply port, compact structure, with functions of manual operation and remote control and in situ, and reset before a signal protection function.
