Description
Technical field
This practicality relates to a kind of mechnical servo press machine, the especially main drive gear of mechnical servo press machine.
Background technique
At present, existing mechanical press machine main transmission mostly is the knuckle press that adopts common electric machine to drive, and employing flywheel stored energy is used break and clutch is braked and clutch.The power consumption of the press machine ubiquity of this form is high, maintenance difficult, shortcoming such as noise is big, and the Motion curves of slide block is non-adjustable.
Ball screw pair has the transmission efficiency height, and transmission accuracy advantages of higher, but owing to be subjected to the restriction of its dynamic load rating, it is mainly used in transmission fewer is used in power transmission, therefore also less being used on the press machine that needs power transmission.
Summary of the invention
In order to realize that ball screw pair applies to servo-pressing machine, ball screw pair is combined with the enlarger of power, and effectively prevent unbalance loading, the utility model proposes the main drive gear of mechnical servo press machine.
For this reason, the technical solution of the utility model is: the main drive gear of mechnical servo press machine comprises actuating motor, speed reducer, ball screw pair and symmetrical multi-link structure; Actuating motor and speed reducer are placed on the upper beam, two driven by servomotor speed reducers, and speed reducer output shaft vertically downward is connected with the screw mandrel of ball screw pair, and the screw of ball screw pair is fixed on the driving sliding block; The symmetry linkage mechanism is hinged on driving sliding block, upper beam and the master slider, and driving sliding block drives master slider by symmetrical linkage mechanism and moves up and down, and realizes the input power of driving sliding block transmitted after amplifying and be the ouput force of master slider.
Further qualification to technique scheme: the nominal diameter scope of ball screw is 40mm-400mm; The movement length scope of symmetry linkage mechanism is 100mm-2000mm.
In the utility model on the ball screw less input power realize bigger ouput force by the amplification of the power of symmetrical linkage mechanism, and effectively prevent unbalance loading, thereby the symmetrical linkage mechanism of high efficiency, highi degree of accuracy and the power amplification of ball screw is realized perfect adaptation.It has energy-conservation, material-saving, environmental protection, low noise, advantage such as efficient, flexible, controlled, can progressively replace traditional mechanical press and oil hydraulic press by promoting the use of.
Compare with the mechnical servo press machine of traditional machine, the utility model patent has following characteristics:
1, main transmission effectively combines ball screw pair and symmetrical multi-connecting-rod mechanism, and the ball screw adjutant rotatablely moves and is converted into straight line motion, and symmetrical multi-connecting-rod mechanism amplifies the delivery pressure of ball screw, and effectively prevents unbalance loading.
2, in the transmission system of this form, ball screw rotating speed and final slide block output speed are non-linear relation, realize the adjustable arbitrarily of the closed loop control of slide block Location accuracy and ram speed curve by the control software of press motion control system special use.
