Abstract
The invention relates to a clamping device, in particular to a double-faced clamping device. The double-faced clamping device comprises a clamp body, a pressing plate, a cam and a bolt, wherein the pressing plate is used for compressing a workpiece; the cam serves as a force application device; the bolt is 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 groove; the right end of the pressing plate is arranged in the wedge groove, so that the pressing plate can swing; the left end of the pressing plate is used for compressing the workpiece; the lower part of the bolt is provided with a strip-shaped groove; and the cam is arranged in the strip-shaped groove and is hinged with the clamp body. The double-faced clamping device disclosed by the technical scheme adopted by the invention is simple in structure and low in cost and is stable.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of double-sided clamp device.
Background technology
Clamping device is widely used for manufacturing.Such as the position relationship 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, the combinations 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.
Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, but in the actual use procedure, the inventor finds that it still exists following some shortcomings: 1, although the device that has some to adopt other power band moving cams to clamp, but its complex structure, cost is higher; 2, there are the point of some clamping device fixation workpiece or face to only have a direction, very unstable when causing clamping work pieces.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure and cost is low, the double-sided clamp device of stable operation.
In order to solve the problems of the technologies described above, the invention provides a kind of double-sided clamp 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 double-sided clamp 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 double-sided clamp workpiece up and down, so more stable, not yielding during clamping work pieces.
As preferred version, consider that pressing plate need to have a fulcrum to make its keep balance when moving up and down, otherwise pressing plate may be offset owing to unbalance stress at clamping work pieces, 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 embodiment of the invention double-sided clamp device.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1, the invention provides a kind of double-sided clamp 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 upper cell wall of bar-shaped trough 3, cam 4 drove bar-shaped troughs 3 and moves 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 lower cell wall of bar-shaped trough 3, cam 4 drove bar-shaped troughs 3 and move straight down, because Action of Gravity Field 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 invention, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
