Abstract

The utility model relates to a dual-station pneumatic fixture. The dual-station pneumatic fixture comprises a reversing valve, an air cylinder, a hinge rod and a crank level, wherein the reversing valve is connected with the air cylinder, the hinge rod is connected with a piston rod of the air cylinder, and the crank level is hinged with the hinge rod and acts on a workpiece. The dual-station pneumatic fixture has the beneficial effects that the adopted pneumatic transmission has the advantages of quick action, no pollution and the like relative to hydraulic transmission, and the requirement on the current environmental protection is met; since a hinge rod-lever boosting mechanism is adopted, the defect of low pressure of pneumatic transmission is made up, and the replacement of the hydraulic transmission with the pneumatic transmission is enabled to become possible.

Description

A kind of Dual-station pneumatic fixture

Technical field

The design relates to Dual-station pneumatic fixture, belongs to machine tooling technical field.

Background technology

Pneumatic Transmission, compared with other transmissions (as hydraulic drive), has convenient sources, pollution-free, cost is low, react a series of advantage such as quick, and Pneumatic Transmission is widely used in jig.But 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.For improving this shortcoming, design a kind of fixture of single air cylinder driven double, can clamp contour workpiece simultaneously.But air-driven system pressure is lower, is generally P=0.4~0.7MPa, this has limited again air-driven development.How in double, to obtain higher thrust, be object of the present invention.

Summary of the invention

For the deficiencies in the prior art, the design adopts force-increasing mechanism to expand thrust output, is specially a kind of toggle one lever boosting mechanism.

For achieving the above object, the design realizes by following technological means:

A kind of Dual-station pneumatic fixture, comprises reversal valve, cylinder, toggle, crank levers, and wherein, reversal valve is connected with cylinder, and toggle is connected with cylinder piston rod, and crank levers is connected with toggle and acts on workpiece.

Preferably, described a kind of Dual-station pneumatic fixture, 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 Dual-station pneumatic fixture, is characterized in that: described cylinder is single-piston rod pneumatic cylinder.

Preferably, described a kind of Dual-station pneumatic fixture, is characterized in that: described cylinder system pressure is 0.4--0.7MPa.

The invention has the beneficial effects as follows: adopt Pneumatic Transmission to there is the advantage such as be swift in motion, pollution-free compared with hydraulic drive, meet current environment protection requirement; Toggle--lever boosting mechanism has made up the little defect of Pneumatic Transmission pressure in employing, makes Pneumatic Transmission replace hydraulic drive to become possibility.

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.

Detailed description of the invention

Below in conjunction with Figure of description, design is further described.

As shown in Figure 1, a kind of Dual-station pneumatic fixture, comprises reversal valve 1, cylinder 2, toggle 3, crank levers 4, and wherein, reversal valve 1 is connected with cylinder 2, and toggle 3 is connected with cylinder 2 piston rods, and crank levers 4 is connected with toggle 3 and by acting on workpiece 5.

Its course of action is: when reversal valve 1 is in Fig. 1 when the state of left position, compressed air enters Rodless cylinder chamber, promotion piston moves downward, piston 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, then be delivered on crank levers 4 force-increasing mechanisms by toggle 3, the amplification again of the length effect realizable force by crank levers 4 mechanisms, workpiece 5 is compressed, the winding machine being formed by toggle one lever the secondary of power increase.After workpiece 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 Dual-station pneumatic fixture, 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 be according to actual needs, different Length Ratios is set, to meet different reinforcement effects.

Preferably, described a kind of Dual-station pneumatic fixture, 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 Dual-station pneumatic fixture, 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.

More than show and described general 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.
