Abstract
The present invention is one kind of synchronously linearly operating interlinkage mechanism and the oil press therewith. The interlinkage mechanism includes two or more linearly operating devices with hinged oscillating part each, and one pull rod with two ends hinged separately to these two oscillating parts. In the interlinkage mechanism, these two linearly operating devices are forced to act synchronously. The oil press with the synchronously linearly operating interlinkage mechanism includes one pedestal, one walking beam, four oil cylinders connected with two synchronously linearly operating interlinkage mechanisms. The oil press has high offset resistance and stable and reliable operation.
Description
Technical field
The present invention relates to the device of two above linearly operatings is connected and synchronizes them the link gear of action, and the hydraulic press that adopts this mechanism.
Background technology
Two devices that above straight line moves as two cylinders arranged side by side, hydraulic cylinder or driving racks etc., when needing its synchronization action, can only be controlled the rotational angular velocity of air pressure, oil pressure or gear usually and realize.This needs complicated detection, control device, and control accuracy is very high than difficulty.For example, on a product assembly line, with manipulator a very big workpiece is pushed to assembly station, and require this workpiece and miscellaneous part position such as mating holes, step cooperate accurate, if with a hydraulic oil cylinder driving, workpiece may be swung by driving force on one point, is difficult to guarantee that workpiece is in comparatively ideal translation state in moving process.If with two above hydraulic oil cylinder driving, workpiece is subjected to driving force at multiple spot, is easy to keep its translation state, but requires very high the synchronization accuracy of a plurality of oil cylinders.In the translation process, be subjected to local resistance as workpiece, still may swing, and destroy desirable translation state.
Be widely used in the four-column type hydraulic press of metal plate punching or brake forming, a walking beam is arranged on its base, workpiece or mould are exerted pressure, an oil cylinder drives walking beam in the middle application of force of walking beam.If it is bigger to be pressed workpiece (or mould), and the bigger pressure of the complex-shaped need of a side, opposite side only needs less pressure, and then the both sides of walking beam are subjected to different reaction forces, and promptly hydraulic press is in the unbalance loading machining state.Add the man-hour walking beam in unbalance loading and be easy to occur or vibration, influence machining accuracy.
Summary of the invention
The present invention is intended to provide a kind of device of two above linearly operatings can being linked together, but makes it the link gear of synchronization action, to guarantee the synchronization accuracy of a plurality of linearly operating devices.
Another object of the present invention is to provide a kind of hydraulic press that uses the link gear of synchronously linearly operating, to improve the anti-bias load ability of hydraulic press.
The link gear of synchronously linearly operating of the present invention, but the device that comprises linearly operating more than two, but at the other hinged goods of furniture for display rather than for use of each linearly operating device, but the driving swing arm of goods of furniture for display rather than for use is hinged with the rod member of linearly operating device by connecting rod, has the pull bar two ends hinged with the transmission arm of adjacent two goods of furniture for display rather than for uses respectively.
But the device of aforementioned linearly operating is meant cylinder, hydraulic cylinder, by tooth bar of gear drive etc.
Hydraulic press of the present invention, comprise base and walking beam, but four jiaos of fixing respectively linearly operating devices of base are hydraulic cylinders, walking beam has four guide pillars to link to each other with the piston rod of each hydraulic cylinder respectively, the other all hinged goods of furniture for display rather than for use of each hydraulic cylinder, the vertically adjacent shared trunnion shaft of two goods of furniture for display rather than for uses is as hinge axis, it is hinged that an actuating arm of radially giving prominence on the hinge axis passes through a connecting rod and piston rod or guide pillar, laterally has the two ends of pull bar hinged with each transmission arm respectively between the transmission arm of two adjacent goods of furniture for display rather than for uses.
The link gear of synchronously linearly operating of the present invention, linearly operating rod member piston rod goods of furniture for display rather than for use, connecting rod, the pull bar of two above linearly operating devices (as cylinder, hydraulic cylinder etc.) is hinged, make the moving member (rod member) of two above linearly operatings become a linkage.The action of one of them piston rod can drive another piston rod synchronization action thereupon by linkage.I.e. two devices of making linearly operating, as cylinder, motorless rod member that can another linearly operating of air cylinder driven; Also two cylinders another workpiece of action drives simultaneously.If driven workpiece is subjected to unbalanced local resistance in moving, cause two cylinders to be subjected to reaction force unequal, the piston rod of two cylinders of cause is connected by linkage, can be delivered on the piston rod of stressed big cylinder by connecting rod by the power of less its output of cylinder of reaction force, promptly a cylinder is to the auxiliary application of force of another cylinder.Described link gear links together two above linearly operating devices, makes it to be forced to synchronization action, and its synchronization action accurately, reliably.Be applicable to the manipulator of carrying out translation motion, also be applicable to and only make parallel mobile plant equipment.
Hydraulic press of the present invention is by the lifting of the hydraulic oil cylinder driving walking beam of four jiaos of bases, to realize being opposite to workpiece or the mould between base and the walking beam.If the complex structure of workpiece or mould, the reaction force to walking beam when pressurized is unbalanced, and big another side force of a side force is little, and then hydraulic press is in the unbalance loading machining state.Because the present invention has adopted aforesaid synchronously linearly operating link gear, that is, laterally the syndeton and the aforementioned synchronously linearly operating link gear of two adjacent oil cylinders are identical; The other hinged shared trunnion shaft of goods of furniture for display rather than for use of two vertically adjacent oil cylinders is a hinge axis, described hydraulic press is with the parallel connection of two synchronously linearly operating link gears and be connected as a single entity, become a cover four post synchronously linearly operating mechanisms, make four guide pillars of walking beam be forced to synchronization action.Thereby described hydraulic press anti-bias load ability is fine, can keep the parallel of walking beam and motion steadily in the processing of any discontinuity equalization.Described hydraulic press can be save back timber than traditional hydraulic press, and the whole volume of equipment is reduced greatly, weight saving, but work is more steady, reliable.
