The manual self-locking pressing device has the following characteristics of reasonable design, rapidness and fastness in clamping workpieces, simplicity and convenience in operation, simple structure, small size, light weight, convenience in carrying, wide application range, low production cost and convenience in popularization and use.
Description
Technical field
The utility model relates to a kind of hold down gag, is 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 using screw thread, or form compound clamp mechanism with other elements or mechanism, there is the advantages such as reliable clamping in helical clamping apparatus, but helical clamping apparatus equally also exists and clamps the shortcomings such as slow motion, clamping efficiency are low.Particularly, in the time using helical clamping apparatus frequently alternately to clamp the workpiece varying in size, need the frequent rotating screw bolt of operating personnel with clamping work pieces, greatly increased operating personnel's labour intensity, reduced production efficiency.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of manually self-locking hold down gag is provided, and it is reasonable in design, clamping work pieces is quick, rapid, simple to operation, there is auto-lock function, simple in structure, 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 adopted in the utility model is: a kind of manually self-locking hold down gag, comprise ladder base for supporting whole device, for the driving arm of drive ram workpiece pressing and for the screw rod of pressure head is installed, it is characterized in that: also comprise frame linking straight-bar and L shaped side link for playing connection function; One end of one end of described ladder base and described frame linking straight-bar is rotationally connected by bearing pin one, the other end of described frame linking straight-bar and described driving arm middle part are rotationally connected by bearing pin two, one end of described driving arm and the middle part of described L shaped side link are rotationally connected by bearing pin three, one end of described L shaped side link is rotatably installed in the middle part of described ladder base by bearing pin four, the other end of described L shaped 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 are hinged, described frame linking straight-bar and described driving arm are hinged, and described driving arm and described L shaped side link are hinged, and described L shaped side link and described ladder base are hinged.
The utility model 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, thereby its clamping work pieces is quick, rapid, operates very simple and convenient.
(2) this manual self-locking hold down gag is in the time of workpiece pressing, bearing pin one, bearing pin two and bearing pin three conllinear, workpiece be applied to reaction force on L shaped side link much all can not make to drive roll over, now this device self-locking.
(3) this manual self-locking hold down gag is simple in structure, 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, be also applicable to the place that other needs Quick-clamped, thereby its scope of application is very extensive.
(5) requirement on machining accuracy of this manual self-locking hold down gag is not high, and a lot of parts are all convenient to produce very much, purchase, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
