Description
Technical field
The present invention relates to assist field, be specifically related to Double-station clamp.
Background technology
The motor-driven fixture be most widely used in machinery manufacturing industry is hydraulic and pneumatic transmission fixture.The advantage of Pneumatic Transmission fixture is, pinching action is rapid, and can not produce environmental pollution, be convenient to Automated condtrol, the system failure is few; In cutting process after clamping, rely on compressed-air actuated potential energy, can continue to keep the clamping force to clamped workpiece, no longer consume the energy, so energy interest rate is high.Major defect is that compressed air is easily revealed, so system pressure lower (being generally 0.4 ~ 0.7MPa), thus causes clamping force can not be very large.The major advantage of hydraulic drive fixture, be that system pressure is high, clamping force is large.Major defect capacity usage ratio is low, and hydraulic pump noise is comparatively large, and easily occurs to reveal because of fluid and volatilize to cause environmental pollution.And there is no the Hydraulic Power Transmission System of accumulator pressurize, in the cutting process after clamping, hydraulic pump still needs running, to keep the clamping force to clamped workpiece; Not only many consumed energies, and skimmer circuit can cause system temperature to raise.
In addition, in production in enormous quantities, often because the problem of fixture clamping, make working (machining) efficiency low.
Summary of the invention
In order to solve the problem, the invention provides one and having hydraulic pressure and Pneumatic Transmission advantage concurrently, shorten the fixture clamping time, the Double-station clamp of enhancing productivity.
Double-station clamp of the present invention, comprise cylinder and step up element, cylinder piston is provided with in described cylinder, described cylinder piston both ends of the surface are provided with a piston rod, the other end of described two-piston bar respectively with a left side, right hydraulic cavities is connected, a described left side, an output piston is provided with in right hydraulic cavities, described two output pistons in opposite directions one end are provided with an output piston bar, described two output piston bars are connected with a connecting rod movable end respectively, the described two connecting rod other ends are fixed, two connecting rods are also connected to a toggle, described two toggles are connected respectively at the element that steps up of diverse location.
Preferably, the length of two-piston bar is all greater than its stroke, and the end of piston rod is provided with sealing device.
Preferably, the axis of two output pistons is positioned on same level line.
Preferably, the length sum of connecting rod and toggle is greater than connecting rod fixing point to the distance of stepping up between element.
The present invention has hydraulic pressure and Pneumatic Transmission advantage concurrently, can shorten the fixture clamping time, enhance productivity.
Accompanying drawing explanation
Fig. 1 is Double-station clamp structural representation.
Reference numeral: 1-cylinder, 2-cylinder piston, 3-piston rod, the left hydraulic cavities of 4-, the right hydraulic cavities of 5-, 6-output piston, 7-connecting rod, 8-toggle, 9-clamping element, 10-workpiece, 11-output piston bar.
Detailed description of the invention
Double-station clamp of the present invention, comprise cylinder 1 and step up element 9, cylinder piston 2 is provided with in described cylinder 1, described cylinder piston 2 both ends of the surface are respectively arranged with a piston rod 3, the other end of described two-piston bar 3 respectively with a left side, right hydraulic cavities 4, 5 are connected, a described left side, right hydraulic cavities 4, an output piston 6 is provided with in 5, described two output pistons 6 in opposite directions one end are provided with an output piston bar 11, described two output piston bars 11 are connected with connecting rod 7 movable end respectively, described two connecting rod 7 other ends are fixed, two connecting rods 7 are also connected to a toggle 8, described two toggles 8 are connected respectively at the element 9 that steps up of diverse location.The length of two-piston bar 3 is all greater than its stroke, and the end of piston rod 3 is provided with sealing device.The axis of two output pistons 6 is positioned on same level line.The length sum of described connecting rod 7 and toggle 8 is greater than connecting rod 7 fixing point to the distance of stepping up between element 9.
When compressed air enters the left air cavity of cylinder 1, promote cylinder piston 2 and move right; Right liquid presses piston pole compresses the fluid of right hydraulic cavities 5, will be applied on right working position output piston 6 after fluid supercharging; 11, right working position output piston bar passes through connecting rod 7 and two-way toggle 8 force-increasing mechanism on the right, is clamped by the workpiece 10 of right clamping element 9 pairs of right working positions.Now, compressed air enters the left chamber of left station output piston 6 simultaneously, and left station output piston bar 11 pulls connecting rod 7 and two-way toggle 8 force-increasing mechanism on the left side, 9, left clamping unit is moved upward, thus the workpiece 10 unclamping left station is to load and unload.
After the cutting process of the right workpiece completes, control system makes compressed air enter right cylinder 1 air cavity, promotes cylinder piston 2 to left movement.Under this state, the workpiece 10 of left station is clamped, and the workpiece 10 of right working position is released.Two the station periodic duties like this in left and right.Because the machining time of workpiece overlapped with the lay day, thus increase substantially production efficiency.
