Abstract
The utility model relates to a clamping device, in particular to a small-angle cam clamping device. The small-angle cam clamping device comprises a clamp body used for tightly pressing the upper surface of a workpiece, a pressing plate used for tightly pressing the lower surface of the workpiece, a cam serving as a force application device, and a vertical guide rod penetrating through the clamp body, wherein the guide rod is connected with the clamp body in a sliding mode, the cam is an edge cam, is connected to the guide rod in a sleeved mode, and is located on the upper surface of the clamp body, and the cam is further provided with a handle capable of rotating the cam; the pressing plate is fixedly connected to the guide rod and located on the lower surface of the clamp body; a return spring is further arranged between the cam and the pressing plate. The small-angle cam clamping device brings convenience to force application, and is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of low-angle cam clamping device.
Background technology
Clamping device is widely used in the manufacturing, is mainly used in clamping and location to workpiece, makes workpiece obvious displacement not take place adding man-hour, improve machining accuracy, so clamping device is considered to requisite parts in the processing industry.
For location and the clamping of miniature workpiece, usually adopt artificial free-hand finishing in order to reduce cost, the drive workpiece pressing that utilizes handle is a kind of common clamping device.
Though existing this 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, and some device utilizes the direct application of force of handle may use very great strength ability starting drive; 2, some adopts other power to drive the device that the extruding pressing plate clamps, but its complex structure, and cost is higher.
The utility model content
The technical problems to be solved in the utility model provides a kind of application of force, simple in structure and low-angle cam clamping device that cost is low be convenient to.
In order to solve the problems of the technologies described above, the utility model provides a kind of low-angle cam clamping device, include chuck body for the workpiece pressing upper surface, be used for the pressing plate of workpiece pressing lower surface, as the cam of force application apparatus, pass the vertical guide post of chuck body; Wherein, described guide post and chuck body are slidingly connected, and described cam is edge cam, are socketed on the guide post, are positioned at the upper surface of chuck body, also be provided with on the cam can rotating cam handle; Described pressing plate is fixedly connected on the guide post, is positioned at the lower surface of chuck body; Also be provided with back-moving spring between described cam and the pressing plate, the upper end of described back-moving spring is connected the lower surface of chuck body, and the lower end is connected on the guide post.
Adopt a kind of low-angle cam clamping device of technique scheme to have following advantage: 1, because this device use is that a low-angle cam comes starting drive, institute is so that the application of force; 2, all be simple the connection and the use manual drives owing to what adopt, so simple in structure, cost is lower.
As preferred version, consider that may drive pressing plate when rotating cam and then rotates, described pressing plate and chuck body junction also are provided with the spacer pin that prevents that pressing plate from rotating.
As preferred version, nut may become flexible when only considering with a nut fixedly, and described guide post upper end is provided with two nuts.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment low-angle cam clamping device.
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 low-angle cam clamping device, include chuck body for the workpiece pressing upper surface, be used for the pressing plate 3 of workpiece pressing lower surface, as the cam 2 of force application apparatus, pass the vertical guide post 4 of chuck body; Wherein, guide post 4 is provided with two nuts, and guide post 4 is slidingly connected with chuck body, and cam 2 is edge cam, is socketed on the guide post 4, is positioned at the upper surface of chuck body, also be provided with on the cam 2 one can rotating cam 2 handle 1; Pressing plate 3 is fixedly connected on the guide post 4, is positioned at the lower surface of chuck body; Also be provided with back-moving spring 5 between cam 2 and the pressing plate 3, the upper end of back-moving spring 5 is connected the lower surface of chuck body, and the lower end is connected on the guide post 4, in addition, also is provided with spacer pin between pressing plate 3 and the clamp body.
Concrete using method is: turning handle 1, and when handle 1 turned to the left side, cam 2 moved up, and guide post 4 drives pressing plate 3 and moves up, back-moving spring 5 compressions, pressing plate 3 workpiece pressings; Turning handle 1, when handle 1 turned to the right, cam 2 moved down, and guide post 4 drives pressing plate 3 and moves down, and back-moving spring 5 flicks, and pressing plate 3 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.
