Description
Technical field
The utility model relates to metal forming machinery metal field, specifically relates to a kind of Novel two-freedom-degree servo-pressing machine in parallel.
Background technology
AC servo motor is applied to the design and research of punching machine in recent years, by AC servo machinery driving ball-screw or crank, can by the motion of conversion of motion needed for slide block by multi-bar linkage, it can change the curve movement of slide block in pole easily, obtain different workpiece deformation speed, be applicable to different Sheet Metal Forming Technologies, ensure the quality of stamping parts, there is very large flexibility.Existing servo-pressing machine, from the angle of theory of mechanisms, its transmission mechanism is all the serial mechanism of single-degree-of-freedom, and servomotor is to rotate (crank) or mobile (ball-screw) mode directly or by executing agency's (multi-connecting-rod mechanism) drives Punching slider.Mechanism with single degree of freedom realizes determining that the principle of moving is that application servomotor drives.Some servo-pressing machine driving mechanisms adopt two servomotor redundant drive, but these two servomotors must ensure synchronous constantly, to avoid inputting the different movement interference caused.Although can input power be increased like this, increase the forming pressure of forcing press, add the difficulty of control strategy, and the bad stability controlled, any one error originated from input all can cause driving mechanism normally to work and even damage.
Summary of the invention
The utility model is a kind of novel press machine provided for the deficiencies in the prior art, thus efficiently solves the problems of the prior art.
The utility model solves the scheme that its technical problem adopts: as shown in Figure 1, 2, and a kind of Novel two-freedom-degree servo-pressing machine in parallel, frame for movement is made up of straight line driving mechanism, parallel institution, Punching slider, guide rail, frame.Described straight line driving mechanism is identical two groups of structure, by two servomotors, two eccentric wheels, two connecting rods, two drive slide blocks to form.Wherein servomotor is fixedly connected with eccentric wheel, and connecting rod connecting eccentric wheel and driving slide block, drive slide block parallel sleeve to be connected on guide rail.Two-freedom-degree parallel mechanism is identical two groups of structure, and often group is made up of four connecting rods, a platform, and four connecting rods are divided into two groups, and often to organize upper end hinged with driving slide block respectively, the other end and platform hinged, platform and Punching slider hinged.Frame is socketed in outside straight line driving mechanism, parallel institution, guide rail and Punching slider.The utility model is with driven by servomotor eccentric wheel band movable slider for input, and the output of each slide block is the rectilinear motion of single-degree-of-freedom, then drives parallel institution, realizes the motion of the Punching slider be connected with parallel institution.
Described motor is servo alternating current generator.
By technique scheme, there is following effect:
The utility model is by the two-freedom-degree parallel mechanism of straight line driving mechanism connected symmetrical dendrimer, and single-degree-of-freedom exports moving both vertically of two platforms, realizes moving both vertically of the Punching slider be connected with two platforms, thus realizes forging and stamping processing action.
The utility model adopts symmetrical structure to improve offset load resistance, reduces Punching slider to the pressure of guide rail, can the precision of long term maintenance forcing press.The conversion of motion of four servomotors is single output by parallel institution, transmits, synthesizes on same Punching slider, increase the forming pressure of power output and forcing press, reduce the difficulty of control strategy, and improve the stability of control.Adopt parallel institution that four motors are worked alone, solve the problem that single-degree-of-freedom forcing press synchronously inputs difficulty, avoid movement interference.
The utility model structure is simple, easy control, low cost of manufacture, existing servo-pressing machine can be solved very well and be subject to the restriction that ball-screw bearing capacity and servomotor power and moment of torsion are less, and the fragile mechanism to cause because machine operation is asynchronous, reduce the problems such as operating efficiency, large-tonnage processing and forging and stamping can be born, and extend the service life of machine.
