Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of two-way clamping device to moving component on the lathe.
Background technology
Clamp mechanism is an important mechanism on the lathe, usually, when moving component for example during the kinematic pair stop motion, hidden danger such as is free to slide for preventing it because of receiving external force, gravity etc. and be subjected to displacement or existing, and just must clamp it.The clamping device that existing clamping force is bigger generally is made up of hydraulic means and leverage, all is unidirectional usually, and it is only to clamped face application of force; Be equivalent to a kind of holding device; When the clamping force requirement was bigger, not only the physical dimension of design got corresponding increase, and in use can cause clamped skew, inclination even distortion; This phenomenon particularly never allows on the large-scale precision lathe at precision machine tool.In addition, this unidirectional clamping device is only applicable to the kinematic pair of the lower and motion state of dynamic response requirement for sliding, and higher or motion state then can not be used for the kinematic pair that rolls for dynamic response requirement.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing clamping device, proposes a kind of workpiece to be applied the clamping device that two-way function power is carried out clamping.
The technical scheme that realizes above-mentioned purpose is: a kind of two-way clamping device, it is made up of a bearing and symmetrical respectively two cover boosting mechanisms, two cover clamping mechanisms, two lever assemblies that are installed in these bearing cross central line both sides.One side of bearing has two symmetrical groups boosting mechanism installing hole, and opposite side has two symmetrical groups clamp mechanism installing hole, and the oil pipe of intercommunication in boosting mechanism arranged, and the breach of clamping moving component is arranged in axis one side of clamp mechanism installing hole; Each lever is installed on the bearing outer face through a support bar that is positioned at position of the fulcrum, and an end of lever is connected with pressure adjusting lever; Every cover boosting mechanism lays respectively in the support in the installing hole separately, and piston rod wherein exposes the termination and the pressure adjusting lever termination holds out against; Every cover clamps mechanism and lays respectively in the support in the installing hole separately, and the clamping bar A termination wherein and the other end of lever hold out against, and are exposed in the breach of bearing outside the B termination of clamping bar.
Above-mentioned every cover boosting mechanism has two groups of afterburning assemblies at least, and every group of afterburning assembly is made up of a piston rod and one group of butterfly spring that is sleeved on the piston rod, and the boosting mechanism installing hole also is a hydraulic jack, and the oil circuit of each hydraulic jack communicates.
Above-mentioned every cover clamps mechanism and has two groups of clamp assemblies at least, and every group of clamp assembly is made up of a clamping bar and a return spring that is sleeved on the clamping bar, the B termination point casing of clamping bar be equipped with the clamping panel seat and with the suitable clamping plate of surface of the work.
Above-mentioned lever is a plane pressing plate, and pressure adjusting lever vertically is screwed in the one of which end, and the number of pressure adjusting lever is corresponding with the number of piston rod in the boosting mechanism.
Bearing is the matrix of this device, all parts all be installed in it above; The dish spring is the element that produces and offer the clamp mechanism clamping force in the boosting mechanism; The effect of pressure adjusting lever is the position of regulating piston bar, thereby confirms the dynamics of piston rod compact disc spring; The pressure oil that gets into boosting mechanism provides power for this device when removing power; Clamp mechanism is to pass to connect clamping force and workpiece is implemented the mechanism that clamps, and return spring wherein is to guarantee that clamping force removes the element that the back clamping bar can reset fully.
This device is installed between the kinematic pair of lathe, and bearing is fixed on the static relatively base body of kinematic pair.This device is in the state that normally off is a clamping work pieces usually, during Installation and Debugging, unclamps pressure adjusting lever earlier, and the dish spring is not stressed, and treats that workpiece is packed into to adjust press rods again behind this device, makes its roof pressure piston rod and makes the clamping force of dish spring compression generations needs.Under this state; The elastic force that the dish spring produces is that clamping force acts on the piston rod and through press rods and is passed to the pressing plate as lever; One end of pressing plate bears the support force of piston rod and produces pressure and promote the clamping bar displacement at its other end, and at this moment, the B of both sides clamping bar end is drawn close.Because what install on the bearing of this device is two cover boosting mechanism, clamp mechanism and lever assemblies of symmetry, therefore, the clamping bar of drawing close just drives clamping plate on it and acts on simultaneously on the workpiece that is pressed from both sides and with workpiece from positive and negative both direction and clamp.When removing power, injection pressure oil in hydraulic jack promotes piston rod the dish spring is compressed once more, and the press rods of this moment is no longer born the top power from piston rod, and the other end of lever receives active force and the perk of return spring, and clamping bar return, workpiece are promptly released.When clamping once more, only need the pressure of removal hydraulic oil to get final product.
This device can use separately, also can a plurality ofly use, and can wait according to the size of required clamping force such as the weight of caught workpiece, inertia and structure and select.
Two cover boosting mechanisms of symmetry are arranged on this device, and every cover boosting mechanism has two groups of generations at least and the afterburning assembly that steps up power is provided, and therefore, the clamping force that boosting mechanism provides has 4 unit servings at least; If when the length ratio of the power arm of lever and resistance arm is 4 to 1, is passed to clamping force that clamp mechanism produces extremely I haven't seen you for ages through lever assembly and be amplified to 16 unit servings, so this device is the very big two-way clamping device of a kind of clamping force.Again because the equal and opposite in direction of clamping force is in the opposite direction, when clamping and unclamping workpiece; Can not make that workpiece squints, tilts, distortion etc.; Therefore, this device is particularly suitable for the clamping of big inertia workpiece, also is fit to the higher or workpiece clamping of motion state for rolling of dynamic response requirement.
