Abstract
The invention discloses a clamping device, in particular to a cam pressing device, which comprises a clamp body, a V-shaped block used for pressing the surface of a workpiece, and a cam used as a force application device, wherein the cam is arranged on the clamp body; the lower end of the pressure plate is hinged to the clamp body, and the upper end of the pressure plate is fixedly connected with the V-shaped block; the cam is hinged on the clamp body and abuts against the pressing plate, and a rotating handle is fixedly arranged on the cam; one end of the reset spring is connected with the V-shaped block, and the other end of the reset spring is fixed on the clamp body; the clamping device is ingenious in structural design, and compared with the existing clamping device, the clamping device is convenient to operate and labor-saving; the clamping force of the clamp is indirectly controlled by using the cam, and the cost is low.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of cam pressing device.
Background technology
Fixture and grip device are widely known by the people, and are widely used for manufacturing.Particularly, fixture has various reference surfaces and/or point, and parts or instrument can accurately be located.In many process, be general to clamp member, so that these parts can keep correct juxtaposition relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying.
For location and the clamping of miniature workpiece, adopt artificial free-hand completing in order usually to reduce costs, by utilizing lever, spring, pulley, cam, the combinations such as jaw reach the effect of clamping work pieces.Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, when artificial hand operation, there are all multioperation inconvenience, the inconvenient application of force, can't suitably grasp the problem such as fixture clamping dynamics.
Summary of the invention
The object of the present invention is to provide a kind of cam pressing device, easy to operate, laborsaving, and have and can grasp fixture clamping dynamics.
The present invention is achieved by the following technical solutions:
A kind of cam pressing device comprises chuck body, is used for the V-block on workpiece pressing surface, as the cam of force application apparatus; Also comprise pressing plate and back-moving spring, the lower end of described pressing plate is hinged on chuck body, and its upper end is fixedly connected with V-block; Described cam is hinged on chuck body and with pressing plate and offsets, and is installed with turning handle on cam; Described back-moving spring one end is connected with V-block, and the other end is fixed on chuck body.
The invention has the beneficial effects as follows:
Structural design of the present invention is ingenious, clockwise rotates handle band moving cam, and cam extruding pressing plate forces pressing plate along the jointed shaft center rotating, thereby makes the V-block workpiece pressing surperficial; When rotating counterclockwise handle, cam loosens the extruding to pressing plate, and under the active force of back-moving spring, V-block loosens the clamping to workpiece, returns original state.Compare with existing clamping device, the present invention is not only easy to operate, laborsaving; The use of cam indirectly held the clamping dynamics of fixture, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
By reference to the accompanying drawings shown in 1, a kind of cam pressing device comprises chuck body 1, is used for the V-block 3 on workpiece pressing 2 surfaces, as the cam 4 of force application apparatus; Also comprise pressing plate 5 and back-moving spring 6, the lower end of described pressing plate 5 is hinged on chuck body 1, and its upper end is fixedly connected with V-block 3; Described cam 4 is hinged on chuck body 1 and with pressing plate 5 and offsets, and is installed with turning handle 7 on cam 4; Described back-moving spring 6 one ends are connected with V-block 3, and the other end is fixed on chuck body 1.
During use, clockwise rotate handle 7 band moving cams 4, cam 4 extruding pressing plates 5 force pressing plate 5 along the jointed shaft center rotating, thereby make V-block 3 workpiece pressing 2 surfaces; When rotating counterclockwise handle 7, cam 4 loosens the extruding to pressing plate 5, and under the active force of back-moving spring 6, V-block 3 loosens the clamping to workpiece 2, returns original state.
Above-described is only the preferred embodiment of the present invention; should be understood 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 also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
