Power tool holders drive mode and part of the function in detail
Power tool holders are tool holders that are mounted on a power turret and can be driven by a servo motor. This type of toolholder is generally used on mill-turn machines, and a few are used on machining centers with power turrets.
The use of power tool holder to improve the quality of manufacturing has a very big help, in the application of CNC machine tools can ensure high precision, and can greatly improve the efficiency of the equipment, after the installation is not easy to fail, the processing range of the equipment can also be greatly expanded. The use of power cutter block for manufacturing can also make the complicated operation steps greatly simplified, and the equipment is more comprehensive, can be punched and side grooving and other production processing.
Power tool holders are generally categorized into German quick-change tool holders VDI standard, Japanese and Korean standards BMT standard, as well as non-standard couplings.
VDI standard has the following brands:
1, a word type: Italy Duplomatic axial into the knife turret special drive teeth DIN1809; Zero positioning tooth type (involute bolster groove type): Germany SAUTER turret improved special drive teeth DIN5480/5482;
2、Plum type: Italy BARUFFALDI turret special drive teeth SPUR MT TOEM;.
3、T-gear: American HASS turret special driving teeth.
4、Slant bevel gear: Germany TRAUB turret special driving teeth.
BMT standard has the following brands:
1, a word type: Korea Doosan DOOSAN (PUMA series) turret special 1809;
2、Zero positioning tooth type: 5480;
3、Special one-piece type: Japan Mori Seiki MORISEIKI (NL series) turret special;
The power head is composed of main motion, feed motion and control device.
Main Motion
The main motion of the power head is driven by a three-phase asynchronous motor, with a high rotational speed and high output power of the spindle, which is very suitable for multi-axis drilling and machining conditions of larger hole diameters.
Feeding motion
The feed movement of the power head is powered by a hydraulic station or compressed air. Because pneumatic and hydraulic transmission has the advantages of fast action response, good environmental adaptability, simple structure, small size, etc., and long working life and convenient source of power source.
Control device
If the feeding movement of the power head adopts compressed air as the power source, then the pneumatic control device is used to control the feeding movement. Its structure is compact, with manual and remote control operation.
