Abstract
A simple cam compressing device comprises a fixing seat which is connected with a stud in a threaded mode. The stud is provided with a compressing plate, spherical washer, a plate spring and a lock nut, wherein the compressing plate is provided with a strip type hole penetrated by the stud, one end of the compressing plate is provided with a clamping end and the other end is provided with a cam groove. A cam is arranged in the cam groove, the cam is provided with a handle, and a revolving shaft of the handle is fixed on the fixing seat; a through-hole is arranged at the bottom of the cam groove between the cam and the plate spring, and the cam is provided with a compressing plate apex pin which penetrates into the through-hole. The handle should be rotated towards the clamping direction to drive the cam to move, and the compressing plate pin arranged on the cam will drive the plate to move horizontally. When the compressing plate moves to the strip type hole and buts against the stud, the handle should be rotated continuously, and the whole compressing plate will rotate with the stud as the shaft under the squeezing of the cam so that compaction of the work piece is achieved.
Description
Technical field
The utility model relates to the grip device in a kind of machining, is 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 also can not lose efficacy during as compressing structure under larger pressure-acting.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.
Utility model content
The purpose of this utility model is to provide a kind of simple and easy cam pressing device, makes its effect of passing through cam realize compression to machined part.
For achieving the above object, the technical solution of the utility model 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, when 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, in the time that pressing plate moves to cylindrical void and withstands stud, be rotated further handle, now whole pressing plate rotation take stud as rotating shaft under the extruding of cam, realizes the compression to workpiece again.Need to unclamp workpiece time, 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 use when handle more comfortable, 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 utility model is described in further detail:
Fig. 1 is the structural representation of the simple and easy cam pressing device embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the simple and easy cam pressing device of the utility model, 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, overlap and have stage clip 21 between holder 1 and pressing plate 3 at stud 2.Have a cylindrical void 31 passing for stud at the middle part of pressing plate 3, 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.
When operation, while rotating counterclockwise handle 8, handle 8 is with moving cam 7 to move, now, the pressing plate ejector pin 71 being arranged on cam 7 is with dynamic pressure plate 3 to move horizontally, and in the time that pressing plate 3 moves to cylindrical void 31 and withstands stud 2, then is rotated further handle 8, now whole pressing plate 3 rotation take stud 2 as rotating shaft under the extruding of cam 7, realizes the compression to workpiece.Need to unclamp workpiece time, 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 preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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 affect effect and practical applicability that the utility model is implemented.
