Abstract

The invention relates to a compression device, in particular to a small-angle cam compression device. The small-angle cam compression device comprises a clamp body, a pressing plate, a cam and a vertical guide rod, wherein the clamp body is used for compressing the upper surface of a workpiece; the pressing plate is used for compressing the lower surface of the workpiece; the cam serves as a force application device; the vertical guide rod passes through the clamp body; the guide rod is glidingly connected with the clamp body; the cam is an end cam, is sheathed onto the guide rod, and is located on the upper surface of the clamp body; the cam is also provided with a handle capable of rotating the cam; the pressing plate is fixedly connected onto the guide rod and is located on the lower surface of the clamp body; and a reset spring is also arranged between the cam and the pressing plate. The small-angle cam compression device disclosed by the technical scheme adopted by the invention is convenient in construction, simple in structure and low in cost.

Description

Low-angle cam clamping device
Technical field
The present invention relates to a kind of clamping device, be 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 occur 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.
Although existing this 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, 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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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 to 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 usefulness 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 actuation owing to what adopt, so simple in structure, cost is lower.
As preferred version, consider and when rotating cam, may be with dynamic pressure plate and then to rotate, can prevent press plate rotary but can not limit the spacer pin that it moves both vertically so between pressing plate and chuck body, be provided with.
As preferred version, nut may become flexible when only considering with a nut fixedly, so increase the stability that a nut can increase nut, is difficult for loosening.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention low-angle cam clamping 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 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 to 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 band dynamic pressure plates 3 move 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 band dynamic pressure plates 3 move down, and back-moving spring 5 flicks, and pressing plate 3 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.
