Abstract
A lever pneumatic clamp comprises a piston cylinder, a reversing valve, a lever, compression elements, a hinge and a rolling wheel; the reversing valve is connected with the piston cylinder; a piston of the piston cylinder is provided with a transverse sliding chute; the rolling wheel is arranged in the transverse sliding chute; one end of the lever is hinged to the rolling wheel, the part, close to the other end of the lever, of the lever is connected with a lever fixing end by virtue of the hinge; the compression elements are symmetrically hinged to the lever at two ends of the hinge. According to the clamp, one cylinder is used for realizing sequential compression of two stations, processing and disassembly are separated, and the processing efficiency is improved; the surface compression elements are adopted, so the manufacturing and replacement are convenient, and the service life of the clamp is prolonged. Meanwhile, force for compressing the workpieces can be reduced, and surface quality of the workpieces is ensured.
Description
Technical field
The design relates to a kind of lever air-actuated jaw, belongs to machining technique field.
Background technology
Existing Double-station clamp, is the separate drive systems of two covers mostly, and a station is just with a cylinder or hydraulic cylinder.So not only fixture cost is high, and once two processing work close proximity. separate hydraulic cylinder or the cylinder of this two cover, cause interfering and cannot use owing to taking larger space, and, dismounting separates and carries out with processing work, also makes working (machining) efficiency not high.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide a kind of lever air-actuated jaw, use one can two workpiece of cylinder clamping, and, in the time of a workpiece of processing, can dismantle another workpiece.
For achieving the above object, the design realizes by following technological means:
A kind of lever air-actuated jaw, it is characterized in that: comprise piston-cylinder, reversal valve, lever, clamping element, hinge, roller, described reversal valve is connected with piston-cylinder, on the piston of described piston-cylinder, be provided with horizontal concrete chute, described roller is arranged in horizontal concrete chute, described lever one end and roller are hinged, by hinge, lever are connected near on the lever of the lever other end with lever stiff end, and clamping element symmetry is articulated with on the lever at hinge two ends.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described clamping element is face contact clamping element.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described cylinder is single-piston rod pneumatic cylinder.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described cylinder system pressure is 0.4--0.7MPa.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: the distance between two clamping elements is less than the distance of the right clamping element to roller.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described lever material is No. 45 steel.
The invention has the beneficial effects as follows: the order that a cylinder of this this fixture is just realized two stations compresses, processing dismounting separately, has improved working (machining) efficiency; It is convenient that face clamping element is manufactured, changed, and extended the service life of fixture.Meanwhile, the power can reduce workpiece pressing time, the surface quality of guarantee workpiece; Employing pneumatic cylinder drives, can compressed air potential energy, and energy-conserving and environment-protective.
Brief description of the drawings
Fig. 1 is fixture work schematic diagram, and Fig. 2 is another work schematic diagram of fixture.
The implication of drawing reference numeral is as follows: 1 clamping element, 2 hinges, 3 levers, 4 workpiece, 5 pistons, 6 rollers, 7 reversal valves.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, 2, a kind of lever air-actuated jaw, it is characterized in that: comprise piston-cylinder, reversal valve 7, lever 3, clamping element 1, hinge 2, roller 6, described reversal valve 7 is connected with piston-cylinder, on the piston 5 of described piston-cylinder, be provided with horizontal concrete chute, described roller 6 is arranged in horizontal concrete chute, described lever 3 one end and roller 6 are hinged, by hinge 2, lever 3 is connected near on the lever 3 of the lever other end with lever stiff end, clamping element 1 symmetry is articulated with on the lever 3 at hinge 2 two ends.
When reversal valve 7 is in the time scheming upper end position shown in l, compressed air enters lower end air cavity, promotes piston 5 and moves upward, lever 3 works, the clamping element 1 that is hinged on lever end compresses left end workpiece 4 downwards, at this moment, just can carry out machining to left side element 4.After process finishes, make reversal valve 7 switch to Fig. 2 position, compressed air enters upper end air cavity, promoting piston 5 moves downward, permanent boosting lever works, the clamping element 1 that is hinged on lever middle part compresses right-hand member workpiece 4 downwards, and now the clamping element 1 of lever 3 ends unclamps left side workpiece 4, then compresses right side workpiece 4.After this, can, in the process that right side workpiece 4 is processed, the workpiece in left side be loaded and unloaded.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described clamping element 1 is face contact clamping element.
The force transmission element of this fixture is simple leverage, and wherein the face contact gripping element hinged with lever, all adopts cylinder to process, and it is convenient to manufacture, change, and has extended the service life of fixture.Meanwhile, the power can reduce workpiece pressing time, the surface quality of guarantee workpiece.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described cylinder is single-piston rod pneumatic cylinder.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described cylinder system pressure is 0.4--0.7MPa.
Cylinder system pressure is excessive, and gas is easily revealed, and increases unsafe factor.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: the distance between two clamping elements is less than the distance of the right clamping element to roller.
According to lever principle, so, the pressure of cylinder output is larger.
Preferably, described a kind of lever air-actuated jaw, is characterized in that: described lever material is No. 45 steel.
More than show and described the design's general principle, principal character and advantage.The technical staff of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described of describing in above-described embodiment and description; do not departing under the prerequisite of the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
