Abstract
The invention relates to a simple cam press device which comprises a fixing seat. A stud is connected to the fixing seat in a threaded mode, a press plate, a spherical washer, a plate spring and a locknut are arranged on the stud in sequence, a bar hole allowing the stud to penetrate through is formed in the middle of the press plate, a claming end is arranged at one end of the press plate, a cam groove is formed in the other end of the press plate, a cam is arranged in the cam groove, a handle is arranged on the cam, and a rotating shaft of the handle is fixedly arranged on the fixing seat. A through hole is formed in the bottom, between the cam and the plate spring, of the cam groove, and a press plate ejector pin inserted into the through hole is arranged on the cam. When the handle is rotated and is rotated in the claming direction, the handle drives the cam to move, the press plate ejector pin arranged on the cam drives the press plate to move horizontally at the moment, the handle is rotated continually when the press plate moves to the bar hole and butts against the stud, the whole press plate rotates with the stud as the rotating shaft under the squeezing of the cam at the moment, and thus pressing of a workpiece is achieved.
Description
Technical field
The present invention relates to the grip device in a kind of machining, be specifically related to a kind of easy cam pressing device.
Background technology
Fixture is a kind of common machined components, has the effect that clamps and locate to be processed.Cam is a kind of common frame for movement, and cam can not lose efficacy during as compressing structure under larger pressure-acting yet.It is a kind of desirable clamping structure.But, because the lift of cam itself is less, if utilize cam to act directly on to be processed above, needs to manufacture very large cam and just can reach processing request, obviously do not meet the requirement of processing, therefore need to design a kind of can rely on cam be used for realizing the device to Workpiece clamping.
Summary of the invention
The object of the present invention is to provide a kind of simple and easy cam pressing device, make its effect of passing through cam realize compression to machined part.
For achieving the above object, technical scheme of the present invention is: simple and easy cam pressing device, comprise holder, a stud is threaded on described holder, on described stud, be provided with successively pressing plate, spheric washer, leaf spring and locking nut, the middle part of described pressing plate is provided with the cylindrical void passing for stud, one end of described pressing plate is bare terminal end, the other end is provided with cam path, in described cam path, be provided with a cam, described cam is provided with a handle, and the rotating shaft of described handle is fixed on holder; The bottom of described cam path is provided with a through hole between cam and leaf spring, and described cam is provided with the pressing plate ejector pin inserting in through hole.
While adopting technique scheme, during turning handle, when to clamping direction turning handle, handle drives camming movement, and now, the pressing plate ejector pin band dynamic pressure plate being arranged on cam moves horizontally, when pressing plate moves to cylindrical void while withstanding stud, be rotated further handle, now whole pressing plate be take stud as rotating shaft rotation under the extruding of cam, realizes the compression to workpiece again.In the time of need to unclamping workpiece, rotate backward handle, pressing plate first rotates cancels the pressure acting on workpiece, then moves horizontally return, has realized unclamping workpiece.Whole device has utilized the feature of cam, simple in structure, and reliability is high.
Further, in order to increase the speed of clamp loose workpiece, described stud is provided with stage clip, and described stage clip is between holder and pressing plate.
Further, for operator more comfortable when using handle, the free end of the described handle handle ball that has been threaded.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the simple and easy cam pressing device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, the simple and easy cam pressing device of the present invention, comprises holder 1, has a screwed hole on holder 1, connects a stud 2 in screwed hole.Stud 2 lower ends are provided with pressing plate 3, spheric washer 4, leaf spring 5 and locking nut 6 successively, at stud 2, between holder 1 and pressing plate 3, overlap and have stage clip 21.At the middle part of pressing plate 3, have a cylindrical void 31 passing for stud, the chuck that one end of described pressing plate 3 is holding workpiece, the other end offers cam path 32, and cam path 32 is interior has placed a cam 7, has fixed a handle 8 on cam 7.The rotating shaft of handle 8 is fixed on holder 1; The bottom of cam path 31 is drilled with a through hole between cam 7 and leaf spring 5, and described cam 7 is provided with the pressing plate ejector pin 71 inserting in through hole.
During operation, while rotating counterclockwise handle 8, handle 8 band moving cam 7 motions, now, be arranged on pressing plate ejector pin on cam 7 71 band dynamic pressure plates 3 and move horizontally, when pressing plate 3 moves to cylindrical void 31 while withstanding stud 2, then be rotated further handle 8, now whole pressing plate 3 be take stud 2 as rotating shaft rotation under the extruding of cam 7, realizes the compression to workpiece.In the time of need to unclamping workpiece, clockwise rotate handle 8, pressing plate 3 first rotates and cancels the pressure acting on workpiece, then moves horizontally return, has realized unclamping workpiece.Whole device has utilized the feature of cam pressing, simple in structure, and reliability is high.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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.
