Background technology
Air-driven working media is clean compressed air, and its advantage easy generation can not pollute as hydraulic drive, and air-driven piston movement speed is significantly higher than hydraulic drive simultaneously, and thus production efficiency is higher; Its shortcoming is due to the as easy as rolling off a log leakage of gas, thus causes system pressure P can not be too high, general P=0.4 ~ 0.7 MPa.Therefore for improving the chucking power of air-actuated jaw, must realize by increasing piston diameter or introduce appropriate force-increasing mechanism two kinds of approach between cylinder and power output device, because first method will increase the overall dimensions of fixture, so be all adopt second method to improve the chucking power of fixture usually.
Summary of the invention
For above-mentioned requirements, the object of the design is to provide a kind of three force-increasing mechanisms, utilizes toggle one oblique
Wedge has carried out three reinforcements.
For achieving the above object, the design is realized by following technological means:
A kind of three force-increasing mechanisms, it is characterized in that: the Toggle Force Amplifier, roller, secondary Toggle Force Amplifier, litter, power output, the back-moving spring that comprise cylinder and arrange in cylinder bilateral symmetry, described cylinder piston is articulated and connected by piston rod and a Toggle Force Amplifier, a described Toggle Force Amplifier and the roller be located in pilot hole are articulated and connected, described secondary Toggle Force Amplifier and roller, the slide bar be located in gathering sill are articulated and connected, the free end of described slide bar is provided with wedge, wedge and power output are slidably connected, and power output is provided with back-moving spring.
Further:
Described one three force-increasing mechanisms, is characterized in that: during described power output stroke end, the angle of a Toggle Force Amplifier and vertical direction is 3-5 °.
Described one three force-increasing mechanisms, is characterized in that: during described power output stroke end, the angle of secondary Toggle Force Amplifier and vertical direction is 3-5 °.

The invention has the beneficial effects as follows: devise and become toggle by toggle with inclined wedge augmenting block combiner---Wedge type tandem sequence force-strenthening mechanism for pneumatic fixture, its chucking power passes through angular effect, achieve three grades of amplifications of power, when power output is certain, reinforcement coefficient is comparatively large, effectively can reduce cylinder pressure or reduce cylinder dimensions; This mechanism can utilize single Input Forces, meet the needs of the mutual vertical operation of outbound course of cylinder piston rod and clamping force, realize air-actuated jaw carries out Bilateral Symmetry clamping action effect to workpiece, suitably increase toggle, wedge tricks, the many sides clamping process to workpiece can be realized.
Accompanying drawing explanation
Fig. 1 is the design's structural representation.
The implication of drawing reference numeral is as follows: 1 cylinder, 2 Toggle Force Amplifiers, 3 rollers, 4 two Toggle Force Amplifiers, 5 litter, 6 power outputs, 7 back-moving springs.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, a kind of three force-increasing mechanisms, it is characterized in that: the Toggle Force Amplifier 2 comprising cylinder 1 and arrange in cylinder 1 bilateral symmetry, roller 3, secondary Toggle Force Amplifier 4, litter 5, power output 6, back-moving spring 7, described cylinder 1 piston is articulated and connected by piston rod and a Toggle Force Amplifier 2, a described Toggle Force Amplifier 2 is articulated and connected with the roller 3 be located in pilot hole, described secondary Toggle Force Amplifier 4 and roller 3, the slide bar 5 be located in gathering sill is articulated and connected, the free end of described slide bar 5 is provided with wedge, wedge and power output 6 are slidably connected, power output is provided with back-moving spring 7.
This structure is primarily of toggle one Wedge type slide bar and power output composition.When Compressed Gas enters the left chamber of cylinder, promote piston and move right, thus promote a Toggle Force Amplifier pressure angle hinged with it and diminish, amplified by the first time of angle enlargement principle realizable force; Now, one time Toggle Force Amplifier pushing rolling wheels moves upward, and again utilizes the second time of angle enlargement principle realizable force to amplify by secondary Toggle Force Amplifier; Mouth in the motion process of secondary Toggle Force Amplifier, its pressure angle reduces, and promote slide bar to left movement, power amplified again by Wedge mechanism, and the power output achieving upside moves downward.Because structure is symmetrical, piston, while driving the power output of upside to move downward, also drives the power output of downside to move upward, thus achieves and clamp the bilateral of workpiece.
When compressed air enters the right chamber of cylinder body, wedge slide bar moves piston driving Toggle Force Amplifier---secondary Toggle Force Amplifier---round about, and power output has moved back reset under the effect of back-moving spring.
Further:
Described one three force-increasing mechanisms, is characterized in that: during described power output 6 stroke end, the angle of a Toggle Force Amplifier and vertical direction is 3-5 °.
Described one three force-increasing mechanisms, is characterized in that: during described power output 6 stroke end, the angle of secondary Toggle Force Amplifier and vertical direction is 3-5 °.
The size of reinforcement coefficient and the pressure angle of lever have direct relation, pressure angle more young pathbreaker obtains larger reinforcement coefficient, when pressure angle level off to zero time reinforcement coefficient will be tending towards infinitely great, but the reason of the aspect such as the accuracy of manufacture due to associated components, in engineering reality, the value of pressure angle can not be too little, generally gets 3-5 °.
Described one three force-increasing mechanisms, is characterized in that: the angle of secondary Toggle Force Amplifier and vertical direction when the angle of a Toggle Force Amplifier and vertical direction equals described power output stroke end during described power output stroke end.
Described one three force-increasing mechanisms, is characterized in that: the inclination angle of described slide bar 5 wedge is greater than the angle of friction between wedge ramp.
Wedge inclination angle size determine mechanism and can realize self-locking, when the inclination angle of wedge is greater than the angle of friction between wedge ramp, the self-locking of mechanism can be realized, thus cylinder can be made in workpiece process to quit work, reach energy-conservation object.
Described one three force-increasing mechanisms, is characterized in that: a described Toggle Force Amplifier 1 is identical with the length of secondary Toggle Force Amplifier 2.
Can make different length as required, length is identical, is convenient to manufacture.
More than show and describe the general principle of the design, 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 described in above-described embodiment and description; under the prerequisite not departing from 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.
