Abstract
The utility model relates to a clamping device, specifically to a double-sided clamping device comprising a clamp body, a pressing plate used for clamping a workpiece, a cam serving as a force-applying device, and a bolt used for supporting the pressing plate. The bolt is connected with the middle part of the pressing plate; the clamp body is provided with a wedge-shaped groove; the right end of the pressing plate is disposed in the wedged-shaped groove and thus can swing; the left end of the pressing plate is used for clamping the workpiece; the lower portion of the bolt is provided with a strip-shaped groove; and the cam is disposed in the strip-shaped groove and is hinged to the clamp body. The double-sided clamping device has the advantages of simple structure, low cost and stability.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of two-sided clamping device.
Background technology
Clamping device is widely used for manufacturing.As the position relation to usually needing in the processes such as the punching press of workpiece, riveted joint, welding to keep correct, so clamping device is considered to requisite parts in the processing industry.
Location and clamping for miniature workpiece utilize lever usually, spring, and pulley, cam, compound modes such as handle reach the effect of clamping work pieces, and wherein to come workpiece pressing be a kind of common clamping device to the drive by cam.
Though existing clamping device can satisfy the clamping demand of workpiece to a certain extent, but in the actual use, the inventor finds that it still exists following some shortcomings: 1, though there is some to adopt other power to drive the device that cam clamps, but its complex structure, cost is higher; 2, there are the point of some clamping device fixation workpiece or face to have only a direction, very unstable when causing clamping work pieces.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure and cost is low, the two-sided clamping device of stable operation.
In order to solve the problems of the technologies described above, the utility model provides a kind of two-sided clamping device, include chuck body, be used for the pressing plate of workpiece pressing, as the cam of force application apparatus, be used for supporting the bolt of pressing plate; Wherein, described bolt is connected with the pressing plate middle part, and described chuck body is provided with wedge-shaped slot, the right-hand member of described pressing plate places it can be swung, the pressing plate left end is used for workpiece pressing, and described bolt bottom is provided with bar-shaped trough, and described cam places this bar-shaped trough interior and hinged with chuck body.
Adopt the two-sided clamping device of technique scheme to have following advantage: 1, be that the hand rotation cam starts because this device adopts, so simple in structure and cost is low; 2, because this device adopts is two-sided clip clamping of workpieces up and down, so more stable, not yielding during clamping work pieces.
As preferred version, consider that pressing plate need have a fulcrum to make its keep balance when moving up and down, otherwise pressing plate may be offset at clamping work pieces owing to unbalance stress, so above bar-shaped trough, be provided with the screw that can play point action.
As preferred version, consider with bolted the time and become flexible easily that so be provided with a spheric washer at bolt, the frictional force that increases between screw thread prevents from becoming flexible.
Description of drawings
Fig. 1 is the structural representation of the two-sided clamping device of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of two-sided clamping device, include chuck body, be used for the pressing plate 2 of workpiece pressing, as the cam 4 of force application apparatus, be used for supporting the bolt 1 of pressing plate, bolt 1 is provided with spheric washer, wherein, bolt 1 is connected with the middle part of pressing plate 2, chuck body is provided with wedge-shaped slot, wedge-shaped slot is provided with screw, the right-hand member of pressing plate 2 places it can be swung, the left end of pressing plate 2 is used for workpiece pressing, and bolt 1 bottom is provided with bar-shaped trough 3, and cam 4 places this bar-shaped trough 3 interior and hinged with chuck body.
Under normal conditions, hand rotation cam 4, when cam 4 maximum radius forwarded the top to and offset with the last cell wall of bar-shaped trough 3, cam 4 drive bar-shaped troughs 3 moved straight up, and bar-shaped trough 3 props up bolt 1 and moves straight up, the left end workpiece pressing of pressing plate 2; Hand rotation cam 4, when cam 4 least radiuses forwarded the below to and offset with the following cell wall of bar-shaped trough 3, cam 4 drove bar-shaped troughs 3 and move straight down, because gravity effect bolt 1 also and then moves straight down, the left end of pressing plate 2 unclamps workpiece.
Above-described only is preferred embodiment of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
