Abstract
The invention provides a main transmission structure of an actuating motor in punching machinery with the characteristics of simple structure, rapidness and high efficiency, and energy saving and environment protection. The main transmission structure comprises a connecting shaft, a rack, a bearing, a rotor, a linking rod mechanism, a stator, a rotor shaft sleeve and a stator shaft sleeve, wherein the connecting shaft is fixed on the rack and is connected with the stator shaft sleeve of an alternative current actuating motor, an eccentricity E exists between the rotor shaft sleeve and the connecting shaft, and a loose fit exists between the linking rod mechanism and the rotor shaft sleeve, which enables the rotor shaft sleeve to rotate in a mating hole of a linking rod.
Description
Technical field
The present invention relates to a kind of structure of press, be specifically related to the main transmission structure of servomotor in a kind of press.
Background technology
The main transmission structure of servomotor in the press, prior art has two or single servo motor directly is contained in a crankshaft two end or an end, perhaps link to each other with bent axle by one-level transmission or two-stage transmission, sliding-block linkage is contained in the eccentric shaft place of bent axle, the driven by motor bent axle changes moving up and down of linkage into, realizes punching press and shaping to sheet material.
Summary of the invention
The objective of the invention is for provide a kind of simple in structure, rapidly and efficiently with the press of energy-conserving and environment-protective in the main transmission structure of servomotor.
Technical scheme of the present invention is: the main transmission structure of servomotor in a kind of press, comprise connecting axle, frame, bearing, rotor, linkage, stator, rotor axle sleeve and stator axle sleeve, described connecting axle is fixed on the frame, and be connected with the stator axis of AC servo motor cover, there are an eccentric E in described rotor axle sleeve and connecting axle, described linkage and rotor axle sleeve matched in clearance make rotor axle sleeve to rotate in the connecting rod mating holes.Because the existence of eccentric E is arranged, and then make linkage in take-up housing, to move up and down.
Preferably be connected between described connecting axle and the stator axle sleeve by key.
Described bearing can be two, is installed in the two ends of motor internal respectively, and described bearing also can be installed in the middle part in the motor.
Servomotor main transmission is as power source with AC servo motor in the press of the present invention, linkage is directly installed on the armature spindle of AC servo motor, (there is not bent axle, armature spindle has substituted bent axle) the direct drivening rod mechanism kinematic of rotor rotation, thickness according to sheet material, directly the control armature spindle rotates suitable angle, thereby drivening rod mechanism moves up and down, and realizes energy-conservation, the quick and accurate punching press to sheet material.
The invention has the beneficial effects as follows:
1, simple in structure, rapidly and efficiently.Compare with the mechanical type main transmission of in the past press machine, linkage directly is connected with the armature spindle of motor, has saved the clutch of mechanical type main transmission and the transmission device of motor, and simple in structure, it is convenient to assemble; No connecting axle is subjected to a side force and the distortion that produces, does not need to do the gyration of whole circle during punching press, according to the needs of ram travel, the control rotor rotates most economical and suitable angle, and the electrical control response is good, thereby can obtain drawing velocity faster, higher working (machining) efficiency.
2, energy-conserving and environment-protective.Compare with mechanical type main transmission, motor does not need to do the gyration of whole circle, makes electric power energy obtain utilizing fully efficiently; Compare with fluid pressure type main transmission, it had both saved the cooling system of hydraulic oil liquid, there are not the leakage of hydraulic oil liquid and the pollution of waste oil disposal yet, in addition, this main transmission power consumption when punching press, not power consumption during not punching press, and hydraulic pressure, mechanical type master motor are in running order all the time, and reduction effect is obvious, and can be according to the size of pressing sheet material load plus-minus drawing velocity automatically, noise is very little during work, belongs to Green Product.
3, can realize accurate punching press and stretch forming processing.The direct control link motion of servomotor do not have the machining of Poewr transmission mechanism and the error of assembling, and lower dead point position can be provided with arbitrarily.Therefore can obtain the higher machining accuracy of press than in the past.
