Description
Technical field
The utility model relates to a kind of metal forming machinery technical field, specifically a kind of Novel two-freedom-degree servo pressure machine mechanism in parallel.
Background technology
Forcing press is the forging equipment of extensive use in metal forming manufacture field, kind and quantity various, be wherein most widely used with punching machine.Although existing a considerable amount of Product Level is high, manufacture meticulous Casting Equipment, forging equipment and even complete production line, be still difficult to change its entry threshold low, manufacture extensive present situation.
The demand for development forcing press of Modern Manufacturing Technology can not only high speed, high accuracy, heavy load running, and larger flexibility should be had, the characteristics of motion can be changed rapidly, easily.And traditional mechanical press is by selecting suitable executing agency and scantling thereof, obtain the typical motion rule that some meet Sheet Metal Forming Technology requirement, but a kind of organization plan cannot meet the requirement of multi-motion rule.Although adopt biased eccentric mechanism, multi-connecting-rod mechanism, non-circular gear mechanism etc. partly can change the slide block movement rule of certain driving mechanism, but after the dimensional parameters of each rod member is determined, the kinetic characteristic of slide block also determines thus do not have flexibility thereupon, is difficult to for different Sheet Metal Forming Technologies.
And servo-pressing machine is compared with conventional press, it has following feature: boost productivity; Goods precision is high; Noise is low, and die life is long; Slide block movement has controllability; The features such as energy-conserving and environment-protective.There is the asynchronous and flexible problem of input power in traditional forcing press, and in our Novel two-freedom-degree servo-pressing machine in parallel, servo control mechanism solves flexible problem, and parallel institution then solves nonsynchronous problem.
Summary of the invention
The utility model to slide in ascending and descending process height and the not enough and a kind of Novel two-freedom-degree parallel connection servo pressure machine mechanism that provides of force problem for the forging press of prior art, with movable slider (moving sets) horizontal movement of driven by servomotor eccentric wheel rotating band for input, parallel institution is adopted to coordinate the motion of two slide blocks, the output of parallel institution is the rectilinear motion of the slide block of single-degree-of-freedom, then drives the pressing block of below to carry out last press work.This apparatus structure is simple, and controlling easily, can provide the power larger than existing servo-pressing machine, can build large-tonnage servo-pressing machine.
The utility model is achieved through the following technical solutions, and it comprises: frame for movement and control structure, specifically have: frame, eccentric mechanism, parallel institution and pressing block.Wherein, described eccentric mechanism is identical two groups of structure, and described parallel institution is two-freedom-degree parallel mechanism, and two eccentric mechanisms are connected with parallel institution respectively, and parallel institution is connected with pressing block again, and frame is socketed on the outside of parallel institution and pressing block.
Described eccentric mechanism comprises: two servomotors, two eccentric wheels, two connecting rods, two driving slide blocks and guide rails, wherein: servomotor is fixedly connected with eccentric wheel, drive slide block to be connected with eccentric wheel by connecting rod, drive slide block to be placed horizontally in guide rail.
Described parallel institution comprises: two groups be arranged in parallel and the symmetrical connecting rod of mirror, and a mobile platform.Wherein, two groups of two, connecting rods be arranged in parallel are one group, and specular is arranged, one end is connected with the driving slide block in two eccentric mechanisms, and the other end is connected with mobile platform.
Pressing block and mobile platform are connected by screw;
Described frame is provided with slide block guide rail and motor support plate.
Two eccentric mechanisms of the present utility model work simultaneously, servomotor wherein rotates by the characteristics of motion of setting, promote connecting rod by eccentric rotation and drive slide block movement, the motion of slider-actuated parallel institution and mobile platform, thus the forging action realizing that pressing block carries out along slide block guide rail moving up and down.Thus, the motion and the power transmission that come from two servomotors are synthesized on pressing block, complete forging and stamping work.
The slide rail of described pressing block, when pressing block moves up and down work, can improve the offset load resistance of pressing block, can the precision of long term maintenance forcing press.Meanwhile, the wearing and tearing at other positions and the distortion of frame can also be reduced.
Described parallel institution is two degrees of freedom, and the conversion of motion coming from two servomotors is single output by this mechanism, transmits, synthesizes on pressing block, makes whole drive system export larger briquetting pressure.Owing to having mechanical coordination function, can not interfere when two servomotors have during error originated from input, make to control difficulty and relatively reduce, and different Forging Technologies can be realized by the motion controlling servomotor.
The utility model low cost of manufacture, can be good at solving the problem that existing servo-pressing machine does not have very large working flexibility.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
As shown in Figure 3, the present embodiment comprises: frame 10,6, two, guide rail 1, two servomotors 8, two eccentric wheels 7, two connecting rods drive slide block 2, two groups of connecting rods be arranged in parallel 3,4, mobile platform 5, pressing block 9.
As shown in Figure 2, guide rail 1, two servomotors 8, two eccentric wheels 7, two connecting rods 6 and two driving slide blocks 2 form eccentric mechanism.
As shown in Figure 3, described parallel institution comprises: two groups of connecting rods be arranged in parallel 3,4, and a mobile platform 5, wherein: two groups be arranged in parallel and the connecting rod 3,4 arranged of specular and mobile platform 5 are hinged, and hinged axis is parallel to each other.
