The definition and classification of Power Head

With the rapid development of science and technology and the needs of large-scale industrial production, many professional manufacturers are using multifunctional efficient combined machine tool, this is to ensure that the product can reach a high machining accuracy, low production cost, high labor productivity, etc. effect. Power head is an important power part of combined machine tool, machine performance is good or bad depends on the quality and performance of power head, but in general combined machine tool design,  power  head can only provide the main movement, its feed movement is associated with hydraulic or mechanical sliding table.

What is a power head? Is installed on the power knife tower, is driven by servo motor power cutter holder. Power head is the basic principle of motor drives a gear change mechanism, can come true to boring, milling, drilling, etc. functions, and is a relatively simple variable speed transmission mechanism. Power head form is varied, depending on the different implementation effects, can be divided into: drilling power head, synchronous tapping power head, milling power head, boring power head, reaming power head and so on.

With synchronous tapping power head is a dual-use, drilling in the meantime also finished in tapping suture. Its front range of screw has cutting function, middle range is tapping chip guide function, bottom range is fixed function. Such as the steel construction and color steel tile construction of stitching is to use the power head.

Automatic feed drilling power head main structure analysis

Abstract: With the rapid development of science and technology and the need for large-scale industrial production. New electric, pneumatic automatic feed drilling has become a guarantee accuracy of product processing, reduce production costs and improve labor productivity and competitiveness of enterprises is one of the key measures.


  Power head is an important power of modular machine tool parts, their quality and performance of the fit and unfit quality directly affect the whole machine tools performance good or bad, but in general, in the design of modular machine tool power head can only provide the main movement, its feed movement is made with matching hydraulic or mechanical sliding table, this is for modular machine tool design and manufacturing has brought great difficulties. To this end, we provide a new type of electric, pneumatic automatic feed drilling power.
  The following is PURROS Company automatic feed drilling head main structure analysis:
(1) as one of the important power components of combination machine tools, electrical, pneumatic, automatic feed drilling power head has small volume, light weight, compact structure, wide practical level, and the advantages of combination and changeful, can according to the needs of users into various forms of combination machine tools.
(2) electric, pneumatic automatic feed drilling power head rotation movement of the (primary motion) using direct drive motor through the synchronous belt, the feed movement using compressed air as power source, realize the spindle “fast forward, the labor into, fast rewind” automatic cycle, feed movement adopts hydraulic damping, feed speed stepless adjustable, feeding schedule continuously adjustable, drilling big power, can also drive more than the root auger shaft work.
(3) Electrical, pneumatic, automatic feed drilling head is a kind of set power head primary motion, feed movement and the main control system in the integration of high-tech products, is the machine, electricity, gas, hydraulic damper fluid technologies integrated application of the results.

The working principle of drilling power head

Drilling power head, is a relatively simple one variable transmission mechanism, a variety of forms, the basic principle is a motor driven gear shift mechanism, can be achieved boring, milling, drilling, and other functions, and some with the guide rail, can be small linear motion, drilling power head is fixed, can not exercise. You can complete the simple processing, general accuracy is not high. Let us say it works drilling power head.


Drill in place the limit switch X1 pressure, contact closure. Press the start button X0, MC master Y0 coil is energized instruction and self-locking, the spindle motor is started. Here with a purpose MC, MCR instruction is to ensure that only the bit to work when the spindle motor is energized Y0, another aim is to simplify the circuit (if OUTY0 Instruction Ladder complex). Meanwhile Y1 energized self-locking, the feed motor energized fast forward. When the limit switch quick hit X2, Y3 energized self-locking, work into the solenoid valve is energized drill work into.


When the work into fast hit the limit switch X3, M0 was electric self-locking, Y1, Y3 loss of power, drill stops. T0 delay of 5 seconds is energized, Y2 energized. Feed motor energized rewind. When rewind (halfway across when the limit switch X2, Y2 due to the normally closed contacts open, do not make the mistake Y3 have electricity) to its original position when you hit the limit switch X1, X1 negated the rising edge of the contact, so that the master Y0 coil power loss, the completion of a drilling process.


Self-feeding drilling heads’ development culture history and classification

Self-feeding drilling heads for machine tool industry friends won’t feel strange, processing method of the tool for our earliest can be traced back to ancient drilling technology, drilling technology is actually The Times is a it is often used in daily life of a kind of a way for the corresponding object processing, from the industrial revolution in Europe until now the rise of modern industrial development to our electrical and mechanical industry, power technology has been around the borehole drilling technology, along with the progress of modern science and the deepening development of industry technology, machined part elaboration and complications in the processing industry, the processing requirements for drilling power head, has greatly improved, especially the precision as the technology improve machining efficiency increases, for all types of drilling power head products in the industry high rotation speed and axial has quickly become a required element of the machine tools, in except to machining center machine mechanical composite technology for common machine tool products have been developed by early horizontal processing way, in the form of more for machine tools on the drilling power head also produced a variety of changes, as some of the blades, a handstand, car milling compound model was popular at that time.


Self-feeding drilling heads across the industry development is to comply with the demand of era of the new processing way for evolution, in this process, a new concept of compound machine is a new technology of combination of tools, its major advantage is that can be easily through the drilling power head on the same machine to make complex parts processing operations, at the same time also can rely on it for a series of drillingtappingmilling,  the degree of micro hole machining methods of work, in the current drilling power head by a mechanical machinery market can be completed before a series of complex parts processing craft, can greatly save on cost and time, in today’s drilling power head processing industry market the spread of new technology and new concept in the research and development department of the factories are in full swing in progress, in either C axis, Y axis degrees or vice spindle head need to match the drilling power head can be equipped with the basic function of the machine tool, drilling power head as a modern machine tools has become one of indispensable processing components, it also makes the functions of drilling power head more diligence is more perfect. We can see that from the perspective of the industry development history of drilling power head of the evolution of the current very mature, believe in its future development will be more advantages.


Self-feeding drilling heads to analyze the market at present, at present is mainly divided into the borehole drilling tapping head and head of these two categories, under this column don’t have some branch model of small class, according to the different machining occasions needed to adapt to different drilling requirements.
