Abstract
A double-station hinge joint piston rod pneumatic clamp is characterized by comprising a reversing valve, an air cylinder, a hinge rod, a crank lever, a hinge joint type piston rod and a resetting spring, wherein a rodless piston is arranged in the air cylinder; the reversing valve is connected with the air cylinder; the rodless piston of the air cylinder is hinged to the hinge joint type piston rod; the resetting spring is arranged in the air cylinder at the lower part of the rodless piston of the air cylinder; the hinge rod is connected with the hinge joint type piston rod; the crank lever is connected with the hinge rod and acts on a workpiece. The double-station design is adopted, the structure of the clamp is compact, materials are saved, and the labor productivity is improved; by virtue of a hinge rod-lever structure, the pressing force of the air cylinder is increased; the hinge joint type piston is added for replacing the design of a fixed piston rod of the air cylinder, the huge advantage that a non-equal altitude workpiece can be clamped is realized, and the air cylinder has the advantages that the work inertia force is small, and the work noise is low.
Description
Technical field
The design relates to double Hinged piston bar air-actuated jaw, belongs to machining technique field.
Background technology
Traditional double station clamp adopts the principle of " station of a cylinder " to design, and this fixture has the shortcomings such as structure is not compact.Meanwhile, because air-driven system pressure is lower, be generally P=0.4～0.7MPa, make cylinder output pressure too small, can not meet the requirement of clamping force.If employing double, owing to clamping the symmetry of station, causes single air cylinder driven Double-station clamp can not clamp non-contour workpiece again simultaneously; Because cylinder weight is generally heavier, when cylinder operation, inertia force is very large again, even if compress non-contour workpiece simultaneously, has again and how to overcome the large problem of cylinder inertia force in fixture work.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide a kind of double Hinged piston bar air-actuated jaw, can increase cylinder-pressing power, can clamp again the fixture of non-contour workpiece simultaneously, has advantages of that cylinder inertia force is little, work noise is low simultaneously.
For achieving the above object, the design realizes by following technological means:
A kind of double Hinged piston bar air-actuated jaw, it is characterized in that: comprise reversal valve, cylinder, toggle, crank levers, radial type piston rod, back-moving spring, wherein, in cylinder, be provided with rodless piston, reversal valve is connected with cylinder, and cylinder rodless piston and radial type piston rod are articulated and connected, and back-moving spring is arranged in the cylinder of cylinder rodless piston bottom, toggle is connected with radial type piston rod, and crank levers is connected with toggle and acts on workpiece.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: the length of described crank levers master arm is greater than the length of crank levers passive arm.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: described cylinder is plunger type pneumatic cylinder.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: described cylinder system pressure is 0.4--0.7MPa.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: the length of described crank levers master arm is the twice of the length of crank levers passive arm.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: described cylinder is single cylinder plunger type pneumatic cylinder.
The invention has the beneficial effects as follows: this design adopts double, not only makes clamp structure compactness, has also saved material, has improved labor productivity; Passing through toggle--lever construction, has increased cylinder-pressing power; Adopt radial type piston rod to replace the design of cylinder fixed piston rod, not only have clamp non-contour workpiece huge advantage, also have advantages of that cylinder operation inertia force is little, operating noise is low.
Brief description of the drawings
Fig. 1 is this clamp structure schematic diagram.
The implication of drawing reference numeral is as follows: 1 reversal valve, 2 cylinders, 3 toggles, 4 crank levers, 5 workpiece, 6 back-moving springs, 7 radial type piston rods, 8 rodless pistons.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, a kind of double Hinged piston bar air-actuated jaw, it is characterized in that: comprise reversal valve 1, cylinder 2, toggle 3, crank levers 4, radial type piston rod 7, back-moving spring 6, wherein, in cylinder 2, be provided with rodless piston 8, reversal valve 1 is connected with cylinder 2, cylinder rodless piston 8 is articulated and connected with radial type piston rod 7, back-moving spring 6 is arranged in the cylinder 2 of cylinder rodless piston 8 bottoms, toggle 3 is connected with radial type piston rod 7, and crank levers 4 is connected with toggle 3 and acts on workpiece 6.
Its course of action is: when reversal valve 1 is in the time illustrating left position, compressed air enters sealing cylinder chamber, promoting rodless piston 8 moves downward, rodless piston 8 is delivered to power on toggle 3 force-increasing mechanisms, carry out the once amplification of power by the angular effect of toggle 3 mechanisms, be delivered on crank levers 4 force-increasing mechanisms by toggle 3 again, the amplification again of the length effect realizable force by crank levers 4 mechanisms, by toggle--winding machine that lever forms the secondary of power increase.Piston moves downward, and after left side workpiece 5 is clamped, radial type piston rod swings, and utilizes toggle--and the compound motion of lever is realized the clamping of the right workpiece 5, clamps not contour workpiece thereby realize simultaneously.After workpiece 5 completion of processing, reversal valve 1 switches to the work of right position, and sealing cylinder cavity pressure disappears, and rodless piston 8 promotes rodless piston 8 and moves upward under back-moving spring 6 effects, makes clamping element unclamp workpiece 5.
Preferably, described a kind of double Hinged piston bar air-actuated jaw, is characterized in that: the length of described crank levers 4 master arms is greater than the length of crank levers passive arm.
