The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Coordinate referring to shown in Fig. 1, SERVO CONTROL tool magazine 1 of the present invention, comprising:
Reductor 10, is fixed on a tool magazine crossbeam 20 by a mounting blocks, and shown in Fig. 2, the driving shaft 110 of described reductor 10 first ends is connected in the rotating shaft 410 of a servomotor 40 by a shaft coupling 30, can transmit compared with high pulling torque reliable operation;
Timing Belt wheels 50, comprise at least two belt wheels, on described Timing Belt wheels 50, are provided with Timing Belt, have stable drive, have buffering, damping capacity, the advantage that noise is low.Shown in Fig. 3, the first belt wheel 510 of described Timing Belt wheels 50 is connected in the output shaft 420 of described reductor 10 second ends by a key 60, and it is accurate that belt wheel transmission has transmission, and nonslipping feature when work, has constant gearratio;
Bevel gear set 70, comprise at least two helical gears, shown in Fig. 4, the first helical gear 710 of described bevel gear set 70 is connected in the second belt wheel 520 of described Timing Belt wheels 50 by a key 80, and described the first helical gear 710 is also fixed on a tool magazine mount pad 90 by bearing block 910 and bearing 920, Helical gear Transmission is steady, noise is low, and gear capacity is strong; Described tool magazine mount pad 90 is fixed on described tool magazine crossbeam 20 by a resetting-mechanism again, and the second helical gear of described bevel gear set 70 has been threaded connection a cutterhead 930.
Above-mentioned servomotor 40 control accuracies are high, operate steadily, have that stronger overload capacity, speed responsive are fast, heating and noise low.Above-mentioned reductor 10 is the high-accuracy planet-gear speed reducer of low back clearance, and this reductor 10 has and operates steadily, and noise is low, high rigidity, high accuracy, single-stage can accomplish that 3arcmin(arc divides, Arc minute) in, high transmission efficiency (single-stage is more than 97%), high moment of torsion/volume ratio, the features such as maintenance-free, are arranged on and on servomotor 40, can well be used for reducing rotating speed, promote moment of torsion, coupling inertia.Above-mentioned Timing Belt wheels 50 and Timing Belt are the transmission of GT type precision synchronous, and fit clearance is little, precision is high, high transmission efficiency (can reach more than 98%), and stable drive, has buffering, cushioning ability, and noise is low.Above-mentioned bevel gear set 70 engagement property are good, are one engagement process gradually between the helical gears gear teeth, and stressed on the gear teeth is also ascending gradually, more descending; The advantages such as therefore to have stable drive, impact and noise little for helical gear engagement, and registration is large, gear capacity is strong, are applicable to high-speed overload.
The kind of drive of SERVO CONTROL tool magazine of the present invention is: first export certain rotating speed and moment of torsion by servomotor 40, servomotor 40 reduces rotating speed by reductor 10, and promote moment of torsion, reductor 10 passes through Timing Belt wheels 50 and Timing Belt transmission rotating speed and moment of torsion again to bevel gear set 70, finally exports rotating speed and moment of torsion to cutterhead 930 by bevel gear set 70.
SERVO CONTROL tool magazine of the present invention adopts servomotor, servomotor is compared with common motor, have the large and little feature of rotary inertia of rotor resistance, therefore servomotor has wider speed adjustable range, linear mechanical property, without " rotation " phenomenon with the performance responding fast.In addition, the rotor of servomotor inside is permanent magnet, the U/V/W three-phase electricity of driver control forms electromagnetic field, rotor rotates under the effect in this magnetic field, the encoder feedback signal that motor carries is simultaneously to driver, driver compares according to value of feedback and desired value, adjusts the angle that rotor rotates.Therefore can control very accurately the rotation of motor, realize accurately location, reliability is high.Planetary reducer is a kind of Novel speed reducer with extensive versatility, and internal gear adopts 20CvMnT carburizing and quenching and roll flute, and it is little that complete machine has physical dimension, and output torque is large, and speed ratio is large, efficiency is high, performance safety is reliable.
The above is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, not departing from the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
