Description
Technical field
The utility model relates to brill milling machine spindle and drives and rotational speed regulation technical field, particularly relate to and a kind of use non-brush permanent-magnet DC motor or permanent magnet ac synchronous motor and the electromechanical such as driver, speed regulator device thereof, realize the technique device boring milling machine spindle rotating switching and stepless speed regulation.
Background technology
In the brill milling equipment course of processing, often need according to different operating mode conversion main shaft working speed, speed does not forward several thousand turns to not etc. from hundreds of per minute.Tradition is bored milling equipment and is usually used AC induction motor as main shaft power, the rotating speed of this motor is decided by motor self structure and ac power frequency, the electric machine structure of actual use procedure is determined, therefore motor speed is decided by ac power frequency substantially, regulate supply frequency by common frequency converter, can motor speed be changed, but common frequency converter volume is relatively large, price is high, and the general milling equipment that bores seldom adopts.Usual way on motor output shaft and machine spindle, is respectively equipped with one group take turns footpath belt pulley not etc., belt transmission is passed through between diaxon, when main shaft working speed needs to change, by the belt pulley that change motor output shaft and main shaft match, to change gearratio, thus obtain different main shaft working speeds.This gear shift mode, must shut down at every turn and just can carry out belt pulley switching, and also need to unclamp and tightening skin belt wheel set bolt again during adjustment pairing belt pulley, operating process is loaded down with trivial details, and several rotating speeds that can only be fixed, and can not realize infinitely variable speeds.
Summary of the invention
The utility model object is to provide one to be suitable for boring milling machine spindle rotating conversion and Variable Speed Technology device, brill milling machine spindle is driven and rotational speed regulation is more economical, more intuitively, more convenient, more practical.
For realizing technique scheme, the dynamo-electric integrated device of the infinitely variable speeds that the utility model adopts, comprises the actuator such as non-brush permanent-magnet DC motor or permanent magnet ac synchronous motor; Comprise non-brush permanent-magnet DC motor or permanent magnet ac synchronous motor driver; Comprise the speed regulator regulating and show rotating speed, described speed regulator is knob potentiometer, push button adjuster or foot-operated adjuster, but is not limited to cited mode.
Preferably, described motor is the novel rare-earth magneto of efficient energy-saving, and motor can built-in Hall sensors, also can not be with Hall element.
Preferably, described motor driver adopts single-phase or three-phase main-frequency ac power supply.Type of drive is the sine-wave current type of drive of driven under square wave current or low cost.
Compared with existing brill milling equipment speed adjusting technique, the utility model tool has the following advantages:
Owing to adopting dynamical novel rare-earth magneto, the course of work is more energy-efficient, and it is more steady that motor exports mechanical performance, and overload capacity is strong.
Owing to adopting electronic speed regulation technology, boring milling equipment does not need separately to establish speed belt wheels, more compact structure, and volume weight is minimized.
Because motor driver adopts single-phase or three-phase main-frequency ac power supply, do not limit by place power supply, relative to employing special DC power supply, the scheme realizing main shaft drives and speed governing is more convenient, more economical.
Owing to adopting electron speed regulator, can be manipulated by this speed regulator at any time, realize turning to, the adjustment of rotating speed and supervision, regulate simple, convenient, directly perceived.
Accompanying drawing explanation
