Abstract
The utility model provides a hydraulic type clamping device, comprising a hydraulic cylinder, a driving rod, a sliding block, a pressing plate, a rotor axis, a clamping base and a fixing platform, etc., wherein the sliding block can move backwards and forwards under the action of the hydraulic cylinder and the driving rod; a driving pressed block can rotate by taking the rotor axis as the fixed pivot, thereby dramatically minimizing the clamp changing time when the platform or the work piece on the platform is moved by releasing or clamping; moreover, the clamping device also has the advantages of strong controllability and simple and reasonable structure.
Description
Technical field
The utility model relates to a kind of fluid pressure type hold down gag.
Background technology
In the process of metal processing, often need fix the parts on movably workbench and the workbench, traditional method adopts the method for bolt or hinge more, not only waste time and energy, and not easy to operate, often fixed workbench, just can't fix parts, can't effectively take into account.
The utility model content
Problem to be solved in the utility model provides a kind of conveniently mode the workpiece on removable workbench and the workbench is fixed.
The utility model provides a kind of fluid pressure type hold down gag for this reason, it comprises hydraulic cylinder, catch bar, slide block, pressing plate, rotating shaft, compresses bearing, stationary work-table etc., described hydraulic cylinder, compress bearing and be installed on the stationary work-table, catch bar, slide block and hydraulic cylinder are connected, rotating shaft is passed pressing plate and is fixed in and compresses on the bearing, pressing plate is positioned at the top that compresses bearing, and described slide block moves around under the effect of hydraulic cylinder and catch bar, and driving briquetting is the fulcrum rotation with the rotating shaft.
Described pressing plate is being semicircle near slide block one end, and the other end is a wedge shape, and the indent of a certain-length and height is arranged between an end of circular arc and the rotating shaft.
The center of gravity of described pressing plate is partially at a semicircular end.
The described bearing that compresses is made up of two mountings, and middle continuous by rotating shaft, two width that prop up between the mounting are a bit larger tham the width of pressing plate.
Its head of described slide block is the inclined-plane of band arc.
When described slide block promotes at hydraulic cylinder and catch bar, its head can arrive pressing plate the semicircle end under, its head can leave the semicircle end of pressing plate fully when hydraulic cylinder and catch bar shrink.
Adopt the hold down gag of above structure, can rapidly the workpiece on travelling table and the workbench be compressed and unclamp, shorten the clamping time greatly, this hold down gag controllability is strong, simple and reasonable.
Description of drawings
Specify the specific embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a front section view of the present utility model.
The specific embodiment:
Fig. 1 is a front section view of the present utility model, hydraulic cylinder 1 in the hold down gag and compress support 6 and be installed on the stationary work-table 7, pressing plate 4 is installed in and compresses on the support 6, under the effect of hydraulic cylinder 1, catch bar 2 moves forward, promoting slide block 3 moves forward, after the semicircle end in contact of slide block 3 and pressing plate 4, the inclined-plane of slide block 3 just holds up the semicircle end of pressing plate 4, pressing plate 4 will be that fulcrum is done clockwise rotatablely moving with rotating shaft 5, the tapered end of pressing plate 4 just moves down and is pressed onto on the travelling table, because hydraulic cylinder 1 can produce very big motive force, thus the semicircle end of pressing plate 4 by strong picking-up, the tapered end of pressing plate 4 can be effectively to pressing down, thereby workpiece on travelling table or the workbench is secured in a press produces displacement
When hydraulic cylinder 1 is return, catch bar 2 drives slide block 3 and retreats, slide block 3 leaves pressing plate 4, because the center of gravity of pressing plate 4 is held in semicircle, pressing plate 4 is under the effect of gravity, and semicircle end can move down, because the indent of a certain-length and height is arranged between a semicircular end and the rotating shaft, semicircle end can be dropped on the stationary work-table 7, and tapered end will move up, thereby unclamps compacted travelling table and the workpiece on the workbench.
