Description
Technical field:
The utility model relates to a kind of building block of embroidery machine, particularly a kind of drive unit of computer embroidery machine embroidery frame.
Technical background:
At present, more and more higher to the automaticity requirement of computerized emboridering machine, promptly require the precision of computerized emboridering machine higher, runnability is more steady, and response speed is faster.And existing computerized emboridering machine adopts four stepper motors as power drive mostly, stepper motor becomes mechanical movement to data signal, drives stretch tight frame and lining by mechanisms such as synchronous cog belts and do plane motion in computerized emboridering machine, drives framework at X, move on the Y direction, drive colour changing and move etc.
In the at present domestic numerical control system, the application of stepper motor is very extensive.Along with the appearance of full digital AC servo, AC servo motor also is applied in the numerical control system more and more.Though both similar on control mode (train of pulse and direction signals) exist bigger difference on serviceability and application scenario.One, control accuracy difference, servomotor is higher than Stepping Motor Control precision; Two, low frequency characteristic difference, stepper motor are prone to the low-frequency vibration phenomenon when low speed.Vibration frequency is relevant with loading condition and drive performance, it is generally acknowledged that vibration frequency is half of empty load of motor take-off frequency.This low-frequency vibration phenomenon that operation principle determined by stepper motor is very unfavorable for the normal operation of machine, and the AC servo motor running is very steady, even also oscillation phenomenon can not occur when low speed.AC servo has the resonance inhibit feature, can contain the rigidity deficiency of machinery, and internal system has the frequency resolution function, can detect the resonance point of machinery, is convenient to system's adjustment.Three, square characteristic difference frequently, the output torque of stepper motor raises with rotating speed and descends, and can sharply descend when higher rotation speed, so its high workload rotating speed is generally at 300～600RPM.AC servo motor promptly in its rated speed (being generally 2000RPM or 3000RPM), can both be exported nominal torque for the output of constant force square, is permanent power output more than rated speed.Four, overload capacity difference, stepper motor generally do not have overload capacity, and AC servo motor has stronger overload capacity.Five, runnability difference, Stepping Motor Control is open loop control, start the too high or excessive phenomenon of losing step or stall that is prone to of load of frequency, the too high phenomenon that is prone to overshoot of rotating speed when stopping, AC servo drive system is closed-loop control, and driver can directly be sampled to the motor encoder feedback signal, inner formation position ring and speed ring, the general phenomenon of losing step or overshoot that stepper motor can not occur, control performance is more reliable.Six, speed responsive performance difference, stepper motor needs 200～400 milliseconds from the static working speed (being generally the per minute hundreds of changes) that accelerates to, the acceleration of AC servo is better, also only need several milliseconds from static its rated speed 3000RPM that accelerates to, can be used for the control occasion of requirement rapid starting/stopping.In sum, AC servo all is better than stepper motor at many aspect of performances.

Described X includes servomotor, reduction box, drive pulley, speed reducing pulley, transmission to servo electrical machinery system and Y to servo electrical machinery system and is with, regulates regulating wheel synchronously, servomotor is fixed on the motor cabinet, drive pulley is fixed on the output shaft of servomotor, speed reducing pulley is fixed in the reduction box, reduction box is fixed on the frame, the motor cabinet top, drive pulley is with synchronously by transmission with speed reducing pulley and is connected, speed reducing pulley is arranged on the corresponding power transmission shaft, and the adjusting regulating wheel is arranged on the deceleration box, the synchrome conveying belt top.
Described two motor cabinets are separately positioned in the column of the centre position of frame back and frame end.
The utility model compared with prior art, its outstanding advantage is: by the tabouret contiguous block with the tabouret of computerized emboridering machine be fixed on X to Y to guide rail be with synchronously, thereby by the forward and reverse rotation of band synchronously of control guide rail, the X that realizes tabouret to Y to move, this device all is better than the servomotor of stepper motor because of having adopted two many performances, makes the mobile steady of tabouret of computerized embroidery machine, noise is little, the precision height, the response speed that runs up is fast, improves the quality of embroidery.
