Abstract
The invention relates to a three-degree-of-freedom mechanical controllable pressure machine tool. The three-degree-of-freedom mechanical controllable pressure machine tool is characterized in that a stamping slide block is connected with a movement platform of a planar three-degree-of-freedom parallel mechanism through a connecting rod, the planar three-degree-of-freedom parallel mechanism is composed of three RPR (wherein R represents a revolute pair and P represents a moving pair) movement branched chains, a driving pair of each branched chain is a P pair, and each branched chain is driven by a servo motor. The planar three-degree-of-freedom parallel mechanism is used for transmitting, combining and converting input from three servo motors into single large power output of the stamping slide block at the end of a pressure machine tool. The planar three-degree-of-freedom parallel mechanism has a function of mechanical coordination, so the planar three-degree-of-freedom parallel mechanism can eliminate movement interference caused by input errors of the three servo motors to reduce the control difficulty. The three-degree-of-freedom mechanical controllable pressure machine tool is simple in structure, easy to control and high in bearing capability.
Description
Technical field:
The invention belongs to substantially without the metal machining technical field of cutting, particularly a kind of three-freedom degree mechanical type controllable pressure lathe.
Background technology:
Stress metal lathe occupies an important position in the industrial production, obtains applying very widely.In order to meet the demand that modern market product is full of flourishes, change is fast, batch is little, quality is high, an important trend of stress metal lathe development is exactly flexibility, digitlization and intellectuality.
For meeting the demand and trend, the servomotor that speed is adjustable progressively replaces the executive component that common electric machine becomes next generation CNC press machine tool.But common power motor relatively, the power of small-power servomotor is less, be difficult to the operating power requirements providing press machine tool, and high-power servomotor is expensive.
For solving above-mentioned technical barrier, some producers and scholar adopt the method for multiple small-power servomotor parallel connection, as the input of press machine tool.But due to press machine tool mechanism this as mechanism with single degree of freedom, and mechanism with single degree of freedom has and determines that the condition of moving be prime mover of mechanism is one.It is synchronous that this just requires that the small-power servomotor of multiple parallel connection must meet input, otherwise will cause movement interference, even can damage servomotor and press machine tool time serious.And require that multiple servomotor stringent synchronization inputs, undoubtedly increase is controlled difficulty.
Summary of the invention:
The present invention is directed to deficiency of the prior art, propose a kind of three-freedom degree mechanical type controllable pressure lathe, it has the advantage that structure is simple, be easy to control, high bearing capacity.
The present invention solves the scheme that its technical problem adopts: a kind of three-freedom degree mechanical type controllable pressure lathe, it utilizes a connecting rod to be connected with end Punching slider by a planar three-freedom-degree parallel mechanism.Planar three-freedom-degree parallel mechanism is containing three movement branched chain, each side chain is RPR, and (R is revolute pair, P is moving sets) side chain, each side chain described drives pair to be P pair, each side chain described, by a driven by servomotor, utilizes planar three-freedom-degree parallel mechanism by the input transmission of three servomotors, synthesis be converted into the single high-power output of end Punching slider.Because planar three-freedom-degree parallel mechanism itself has mechanical coordination function, the movement interference that three groups of servomotor error originated from inputs cause can be eliminated, reduce and control difficulty.
Accompanying drawing illustrates:
Fig. 1 is three-freedom degree mechanical type controllable pressure lathe schematic diagram of mechanism.
In Fig. 1,1 is frame, and 2,4,5,6,8,9,11 is revolute pair, and 3,7,10 is moving sets, and 12-19 is bar, and 20 is slide block.
Detailed description of the invention:
Below in conjunction with accompanying drawing 1 shownschematically embodiment the invention will be further described:
As shown in Figure 1 in embodiment: slide block 20 is connected with the bar 12 (motion platform of planar three-freedom-degree parallel mechanism) of planar three-freedom-degree parallel mechanism by bar 19.Described slide block 20 is that the end of whole mechanism exports, i.e. the Punching slider of Three Degree Of Freedom controllable pressure lathe.Described planar three-freedom-degree parallel mechanism passes through three movement branched chain connecting rods 12 and frame 1, revolute pair 2 and 4, moving sets 3, and bar 13 and 14 forms the first movement branched chain; Revolute pair 5 and 9, moving sets 10, bar 15 and 16 forms the second movement branched chain; Revolute pair 6 and 8, moving sets 7, bar 17 and 18 forms the 3rd movement branched chain.Each side chain of described planar three-freedom-degree parallel mechanism is by driven by servomotor, and the driving pair of each movement branched chain described is moving sets.The input of the servomotor of described three movement branched chain is transmitted by described planar three-freedom-degree parallel mechanism, synthesize and be converted into the high-power single output of slide block 20, realizes large load stamping press task.Described planar three-freedom-degree parallel mechanism itself has mechanical coordination function, can eliminate the movement interference that three groups of servomotor error originated from inputs cause, and reduces and controls difficulty.
