The invention discloses a single-station pneumatic pressing fixture. The single-station pneumatic pressing fixture comprises an air cylinder and a force-increasing lever. A rodless piston is arranged in the air cylinder in a sliding mode, and a first vertical groove is formed in the middle of the rodless piston. A first idler wheel and a second idler wheel are rotationally installed at the upper end and in the middle of the force-increasing lever respectively, the first idler wheel is arranged in the first vertical groove, and the second idler wheel is arranged in a second vertical groove in the middle of a wedge. The lower end of the force-increasing lever is rotationally installed on a pivot. A wedge pressing head used in cooperation with the wedge for pressing a workpiece is arranged on the lower side of the wedge, and a reset spring is arranged on the lower side of the wedge pressing head. The single-station pneumatic pressing fixture has the advantages that the pressure of the pneumatic system can be remarkably reduced by the adoption of the lever force-increasing structure, and the single-station pneumatic pressing fixture has a self-locking function and is remarkable in energy-saving effect, reasonable in design, simple in structure, convenient to operate, excellent in rigidity, long in service life, wide in application range, low in production cost and convenient to popularize and use.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of single station pneumatic compressing fixture.
Background technology
Pneumatic Transmission driving medium used is clean compressed air, thereby in use can not produce pollution, but air-driven fatal shortcoming is that system pressure can not be too high, thereby obtains larger pressure as needed, and just must greatly increase the diameter of cylinder.The effective way addressing this problem, the one, after utilizing mechanical force amplifier that the power output of cylinder is amplified, remake for workpiece; The 2nd, Pneumatic Transmission and the reinforcement such as wedge or the cam parts with auto-lock function are combined, so that can stop supplies compressed air in process, realize energy-conservation.But the above-mentioned force-increasing mechanism with auto-lock function, when pressure angle is little to a certain extent time, the needed active force that unclamps, significantly be greater than the active force applying while clamping, and this has increased the difficulty of matching to gas pressure undoubtedly.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of single station pneumatic compressing fixture is provided, it has lever boosting mechanism, the pressure that can significantly reduce pneumatic system, has auto-lock function, and energy-saving effect is remarkable, reasonable in design, simple in structure, easy to operate, good rigidly, long service life, applied widely, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of single station pneumatic compressing fixture, comprise cylinder and boosting lever, it is characterized in that: described cylinder interior is slided and is provided with rodless piston, described rodless piston middle part is provided with vertical slot one, the upper end of described boosting lever and middle part are rotatablely equipped with respectively roller one and roller two, described roller one is arranged in vertical slot one, described roller two is arranged in the vertical slot two at wedge middle part, the lower end of described boosting lever is rotatably installed on fulcrum, described wedge downside is provided with the wedge pressure head for workpiece pressing being mated, described wedge pressure head downside is provided with back-moving spring.
Above-mentioned single station pneumatic compressing fixture, is characterized in that: described roller one and roller two are all hinged on boosting lever.
Above-mentioned single station pneumatic compressing fixture, is characterized in that: the lower end of described boosting lever is hinged on fulcrum.
The present invention compared with prior art has the following advantages:
(1) this list station pneumatic compressing fixture has lever boosting mechanism, can significantly reduce the pressure of pneumatic system, greatly reduces the volume of whole system simultaneously.
(2) this list station pneumatic compressing fixture adopts Wedge mechanism, has auto-lock function, can make when needed air pump quit work, and energy-saving effect is remarkable.
(3) this list station pneumatic compressing fixture is reasonable in design, simple in structure, and operating personnel only need be placed on workpiece on workbench, and this fixture can complete clamp operation automatically, uses very easy.
(4) this list station pneumatic compressing fixture good rigidly, long service life, applied widely.
(5) a lot of parts of this list station pneumatic compressing fixture are all convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.
