Abstract
The utility model discloses a pneumatic double-station idler wheel fixture. The pneumatic double-station idler wheel fixture comprises a reversing valve, a cylinder, a hinge rod, a crank lever and an idler wheel; a transverse chute is formed in a cylinder piston rod, and the idler wheel is mounted in the transverse chute; the reversing valve is connected with the cylinder, the hinge rod is connected with the center of the idler wheel, and the crank lever is connected with the hinge rod and acts on a workpiece. By means of the double-station design, the fixture structure is compact, material is saved, and the labor efficiency is improved; by means of the hinge rod-lever structure, the cylinder compression force is increased; through matching the idler wheel with the chute, the pneumatic double-station idler wheel fixture can clamp different heights of workpieces, the inertia force of the cylinder is small, and the working noise is low.
Description
Technical field
The design relates to a kind of double roller 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 following shortcoming: structure is not compact, takes up room large; Be unfavorable for saving, cost rises; Working (machining) efficiency is low.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, during 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 roller air-actuated jaw, can clamp non-contour workpiece simultaneously, and roller frictional force little, be swift in motion, cylinder inertia force is little, operating noise is low.
For achieving the above object, the design realizes by following technological means:
A double roller air-actuated jaw, is characterized in that: comprise reversal valve, cylinder, toggle, crank levers, roller; In described cylinder piston rod, be provided with horizontal concrete chute, described roller is arranged in described horizontal concrete chute; Described reversal valve is connected with cylinder, and described toggle is connected with described roller center, and crank levers is connected with toggle and acts on workpiece.
Preferably, described a kind of double roller 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 roller air-actuated jaw, is characterized in that: described cylinder is single-piston rod pneumatic cylinder.
Preferably, described a kind of double roller air-actuated jaw, is characterized in that: described cylinder system pressure is 0.4--0.7MPa.
The invention has the beneficial effects as follows: the design of double, not only make clamp structure compact, also saved material, improved labor productivity; Passing through toggle--lever construction, has increased cylinder-pressing power; Employing gyro wheeling concrete chuting coordinates, not only have clamp non-contour workpiece huge advantage, also have advantages of that cylinder operation inertia force is little, operating noise is low.
Accompanying drawing explanation
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 rollers.
The specific embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1,
A double roller air-actuated jaw, is characterized in that: comprise reversal valve 1, cylinder 2, toggle 3, crank levers 4, roller 6; In described cylinder piston rod, be provided with horizontal concrete chute, described roller 6 is arranged in described horizontal concrete chute; Described reversal valve 1 is connected with cylinder 2, and described toggle 3 is connected with described roller 6 centers, and crank levers 4 is connected with toggle 3 and acts on workpiece 5.
Its course of action is: when reversal valve 1 is when illustrating left position, compressed air enters Rodless cylinder chamber, promotion piston rod moves downward, piston rod is delivered to power on toggle 3 force-increasing mechanisms by roller 6, by the angular effect of toggle 3 mechanisms, carry out the once amplification of power, by toggle 3, be delivered on crank levers 4 force-increasing mechanisms 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, roller 6 moves right, and utilizes toggle--and the compound motion of lever is realized the clamping of the right workpiece 5, thereby realize, clamps not contour workpiece simultaneously.After workpiece 5 completion of processing, reversal valve 1 switches to the work of right position, and compressed air enters cylinder 2 rod chambers, and piston moves upward, and makes clamping element unclamp workpiece 5.
Preferably, described a kind of double roller 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.
The reinforcement of crank levers 4 is to determine with the length of crank levers 4 master arms and the Length Ratio of crank levers 4 passive arms, can according to actual needs different Length Ratios be set, to meet different reinforcement effects.
Preferably, described a kind of double roller air-actuated jaw, is characterized in that: described cylinder 2 is single-piston rod pneumatic cylinder.
Plunger type cylinder 2 is a kind of single-acting formula pneumatic cylinders, can only realize the motion of a direction by atmospheric pressure, is applicable to the design's actual use.
Preferably, described a kind of double roller air-actuated jaw, is characterized in that: described cylinder 2 system pressures are 0.4--0.7MPa.
Cylinder 2 system pressures are excessive, and gas is easily revealed, and increase unsafe factor, should be by cylinder system pressure limit in the reasonable scope.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
