Abstract
The utility model discloses a clamping device and particularly relates to a raised head clamping device with double hinge joints. The raised head clamping device with the double hinge joints comprises a clamp body, a clamping jaw used for tightly pressing the upper surface of a workpiece, and a bolt used for fixing the clamping jaw. The bolt is hinged with the clamp body. The clamping jaw comprises a driven end and a driving end, wherein the driven end plays a clamping role, and the driving end plays a force application role and is hinged with the clamp body. The driving end of the clamping jaw is provided with a notch, and the bolt is located in the notch. A return spring is connected outside a bolt body between the clamping jaw and the clamp body in a sleeved mode. The raised head clamping device with the double hinge joints is simple in structure and easy to operate, and solves the problems that an existing clamping device is complex in structure and cumbersome to operate.
Description
Technical field
The utility model relates to a kind of clamping device, especially the plush copper clamping device of a kind of pair of pin joint.
Background technology
The lathe clamping device be on lathe in order to a kind of device of clamping workpiece, its effect is with the workpiece location, so that workpiece obtains the tram of relative lathe or cutter, and workpiece is clamped reliably.Can not destroy the tram that workpiece occupies during clamping in anchor clamps, clamping force is wanted suitably, should guarantee that workpiece is not mobile in process, does not rotate, do not vibrate, do not make surface of the work damage, distortion again because clamping force is excessive, structure should be tried one's best simply, makes, keeps in repair and will make things convenient for, the operation of clamp mechanism should safety, convenient, rapidly, laborsaving.Therefore, the raising of clamping device and operating personnel's improvement and machine tool capability has close relationship.Present clamping device structure more complicated, and need hydraulic oil that power is provided, increased production cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, operation and the clamping device of energy-conserving and environment-protective easily.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The plush copper clamping device of a kind of pair of pin joint, comprise chuck body, be used for the workpiece pressing upper surface jaw, be used for the bolt of stationary jaw; Described bolt and chuck body are hinged, and described jaw has comprised the driven end of clamping action and played the drive end of application of force effect that drive end and chuck body are hinged; The drive end of described jaw is provided with notch, and bolt is positioned at described notch, the outer socket back-moving spring of the body of bolt between jaw and the chuck body.
The course of work of the present utility model:
Pin joint along jaw and chuck body is pulled jaw counterclockwise, makes the driven end of jaw push down workpiece surface, makes it to push down jaw along the counterclockwise wrenching bolt of the pin joint of bolt and chuck body, screws nut and makes the driven end of jaw with Work-sheet pressing.
Unclamp nut, along the clockwise wrenching bolt of the pin joint of bolt and chuck body, back-moving spring recovers elastic deformation, with the jaw bullet from workpiece.
Adopt the utility model that following technique effect is arranged:
1, simple to operate, pull jaw by people's hand and push down workpiece, screw the clamping that nut is realized workpiece.
2, do not need hydraulic means, low cost of manufacture, and energy-saving and environmental protection.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the plush copper clamping device of the two pin joints of the utility model.
The specific embodiment
As shown in Figure 1, the plush copper clamping device of of the present utility model pair of pin joint, comprise chuck body 1, be used for the workpiece pressing upper surface jaw 2, be used for the bolt 3 of stationary jaw 2; Bolt 3 is hinged with chuck body 1, and jaw 2 has comprised the driven end 21 of clamping action and played the drive end 22 of application of force effect that drive end 22 is hinged with chuck body 1; The drive end 22 of jaw 2 is provided with the notch (not shown), and bolt 3 is positioned at described notch, the bolt 3 external socket back-moving springs 4 between jaw 2 and the chuck body 1.
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 also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
