The utility model belongs to a kind of motor servo-loading device, applicable to the loading system of machinery such as CNC turret punch press, is specially adapted to the use occasion that displacement, speed, position and load capacity to the course of work has requirement of real-time control.
Charger of the prior art has modes such as machine driving loading, hydraulic drive loading usually.For example, the CNC turret punch press of unit exploitation such as Jinan China casting metal forming machinery research institute is exactly the load maintainer of the above-mentioned form that adopts.The machine driving load mode is to pass through the belt drives flywheel by common electric machine, makes the upper and lower reciprocating motion of slide block by clutch, brake and eccentric shaft (or elbow-bar mechanism) again, and its characteristics of motion is immutable, and upper and lower end points position is fixed.Can not satisfy the difference control requirement of different process to displacement, speed, position.Mechanical structure is also comparatively complicated.The hydraulic drive load mode is to provide pressure oil by hydraulic power unit, drives the oil cylinder piston reciprocating motion through electric hydraulic control valve, realizes workpiece loading.System element is many, complex structure.
The purpose of this utility model is at the shortcoming and defect that exists in the prior art, provides a kind of simple in structure, and displacement, speed, position and the load capacity of the course of work are controlled in real time, can satisfy the charger of different process needs.
The agent structure of the said servo-loading unit of the utility model is formed by unit constructions such as the motor with servo performance, matrix, screw rod, nut, loading head, flange, bearings, it constitutes: be provided with screw rod 2 and nut 8 in matrix 7, screw rod 2 is arranged among the bearing 5,6, and run through among nut 8, bearing 5 is placed in the middle part of locating flange 3; Loading head 9 is placed in the bottom of nut 8, and stretches out from the hole of flange 11; Matrix 7 and nut 8 are provided with the guiding mechanism of restriction nut 8 rotations; Matrix 7 is provided with the power drive mechanism of drive screw 2, and said power drive mechanism can be made up of motor 1 and variable transmission mechanism 4.
The operation principle of the said motor servo-loading device of the utility model is as follows: motor 1 is the motor with servo performance.Screw rod 2 is installed in the middle part of matrix 7 by bearing 5,6 and locating flange 3, makes it can realize forward and reverse rotation; Said nut 8 adopts the high-abrasive material of the low-friction coefficient more than one deck or one deck to combine, nut 8 connects as a whole in loading head 9, on nut 8 guiding mechanism is set, makes when screw rod 2 rotates, nut 8 drives loading head 9 and keeps straight reciprocating motion.When motor 1 is rotated in the forward, be rotated in the forward by variable transmission mechanism 4 drive screws 2, be converted to the motion of stretching out of loading head 9 through nut 8; When motor 1 reverse rotation, loading head 9 is made return movement.The rotating speed of SERVO CONTROL motor 1, torque, corner just can change movement velocity, power and the displacement of loading head 9, and two groups of parameters become corresponding relation.
The said motor servo-loading device of the utility model has following advantage:
1. can not only control in real time or limit displacement, speed and the load capacity of the course of work, can also accurately locate, can satisfy the kinds of processes requirement;
2. when using the motor servo-loading device more than two simultaneously, can realize synchronously or asynchronous behavior;
3. simple in structure, volume is little, but profile random device kind change, simplified the general structure of machine;
4. when load is not too big, can save variable transmission mechanism,, make structure more succinct with the direct drive screw of motor;
5. the reliability height of servo techniques, failure rate is low;
6. can be applied on CNC turret punch press, digital control plate bending machine and other machinery equipment.
