Abstract
The invention discloses a manual self-locking compression device. The device comprises a step base, a driving arm and a screw and further comprises a connection frame straight rod and an L-shaped connection frame rod which have a connection effect. One end of the step base is in rotary connection with one end of the connection frame straight rod through a first hinge pin, and the other end of the connection frame straight rod is in rotary connection with the middle of the driving arm through a second hinge pin. One end of the driving arm is in rotary connection with the middle of the L-shaped connection frame rod through a third hinge pin, one end of the L-shaped connection frame rod is mounted in the middle of the step base in a rotatable mode through a fourth hinge pin, the screw is fixed at the other end of the L-shaped connection frame rod, and a pressure head is welded or fixed through threads at the lower end of the screw. The device has the advantages of being reasonable in design, rapid in work-piece clamping, simple and convenient to operate, provided with a self-locking function, simple in structure, small in size, low in weight, convenient to carry, wide in application range, low in production cost and convenient to popularize and use.
Description
Technical field
The present invention relates to a kind of hold down gag, be specifically related to a kind of manual hold down gag with auto-lock function.
Background technology
At present, clamping device is all widely used in all trades and professions, helical clamping apparatus is current modal clamping device, the direct clamping work pieces of its general screw thread, or form compound clamp system with other elements or mechanism, there is the advantages such as reliable clamping in helical clamping apparatus, but helical clamping apparatus equally also exists the shortcomings such as pinching action is slow, clamping efficiency is low.Particularly when using helical clamping apparatus frequently alternately to clamp the workpiece varied in size, needing the frequent rotating screw bolt of operating personnel with clamping work pieces, considerably increasing the labour intensity of operating personnel, reduce production efficiency.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of manual self-locking hold down gag, it is reasonable in design, clamping work pieces is quick, rapid, simple to operation, have auto-lock function, structure is simple, volume is little, lightweight, be convenient to carrying, 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 manual self-locking hold down gag, comprising the ladder base for supporting whole device, for the driving arm of drive ram workpiece pressing and the screw rod for installing pressure head, it is characterized in that: also comprising the frame linking straight-bar for playing connection function and L shape side link; One end of described ladder base and one end of described frame linking straight-bar are rotationally connected by bearing pin one, be rotationally connected by bearing pin two in the middle part of the other end of described frame linking straight-bar and described driving arm, one end of described driving arm and the middle part of described L shape side link are rotationally connected by bearing pin three, one end of described L shape side link is rotatably installed in the middle part of described ladder base by bearing pin four, the other end of described L shape side link is installed with screw rod, and described screw rod lower end is welded or is installed with pressure head by screw thread.
Above-mentioned manual self-locking hold down gag, it is characterized in that: described frame linking straight-bar and described ladder base hinged, described frame linking straight-bar and described driving arm hinged, described driving arm and described L shape side link hinged, described L shape side link and described ladder base hinged.
The present invention compared with prior art has the following advantages:
(1) this manual self-locking hold down gag design is very reasonable, and operating personnel only need press downwards and drive arm can make pressure head workpiece pressing, and thus its clamping work pieces is quick, rapid, operates very simple and convenient.
(2) this manual self-locking hold down gag is when workpiece pressing, bearing pin one, bearing pin two and bearing pin three conllinear, and workpiece is applied to that reaction force on L shape side link is much all can not make driving roll over, now this device self-locking.
(3) this manual self-locking hold down gag structure is simple, and volume is little, lightweight, is convenient to carrying.
(4) this manual self-locking hold down gag is not only applicable to Machining Technology field, is also applicable to the place that other needs Quick-clamped, and thus its scope of application widely.
(5) requirement on machining accuracy of this manual self-locking hold down gag is not high, and a lot of parts are convenient to produce, buy all very much, and thus 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.
