Abstract
The invention discloses a parallel linkage clamping mechanism which comprises a base. A supporting rod is fixedly arranged on the base. The supporting rod is sleeved with a pressing plate. The pressing plate is provided with two pressing blocks in a hinged mode. The pressing blocks are symmetrically arranged at the two ends of the supporting rod. Four V-shaped grooves are formed in the base and located under the pressing blocks. The V-shaped grooves are symmetrically arranged on the two sides of the supporting rod. A threaded section is arranged at the portion, above the pressing plate, of the supporting rod. A nut is arranged on the threaded section. The nut is rotated to drive the pressing plate to move downwards along the supporting rod and clamp pipe fittings placed inside the V-shaped grooves. Due to the fact that the two pressing blocks are hinged to the pressing plate, the pipe fittings are compressed through the pressing blocks. Even if the pipe fittings placed into the two V-shaped grooves on the same side are different in size, all the pipe fittings can be simultaneously clamped in the mode that the pressing blocks rotate around the hinged point. In theory, all the pipe fittings bear the same clamping force, and the problems that the pipe fittings are damaged due to clamping and cannot be clamped are avoided.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, be specifically related to a kind of parallel linking clamping mechanism.
Background technology
Fixture adds to be used for rapid fastening workpiece man-hour, makes lathe, cutter, workpiece keep the process unit of correct relative position.Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, efficient, precision, compound, intelligence, environmental protection future development drive under, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.Jig, is conducive to the machining accuracy, the stabilized product quality that ensure workpiece; Be conducive to raising labour productivity and reducing costs; Be conducive to improving workman's working condition, ensure safety in production; Be conducive to enlarger bed process scope, realize " a tractor serves several purposes ".Fixture is usually by compositions such as setting element (determining the tram of workpiece in fixture), clamping device, tool setting induction element (determine the relative position of cutter and workpiece or guide tool orientation), indexing means (make workpiece can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).At present, when processing pipe fitting, needing to clamp pipe fitting, prevent it from moving and rotate.Conventional fixture once can only clamping pipe fitting, efficiency is lower, main Problems existing is between pipe fitting or there is the difference of size between V-arrangement fixture block, the particularly pipe fitting of different model, if unified plane chuck carries out clamping, the stressed of each pipe fitting not etc. does not easily cause damage, and the pipe fitting even causing size less cannot the situation of clamping.
Summary of the invention
The object of the present invention is to provide a kind of parallel linking clamping mechanism, by structural improvement, can the pipe fitting of the multiple different size of clamped one time, and the chucking power of flat each pipe fitting horizontal, prevent the problem that can not clamp.
For achieving the above object, technical scheme of the present invention is: parallel linking clamping mechanism, comprises base, described base is fixed with a pole, described pole is arranged with a pressing plate, described pressing plate is hinged with two briquettings, and described briquetting is symmetricly set on the two ends of pole; Described base offers four V-shaped grooves, described V-shaped groove is positioned at immediately below briquetting, and described V-shaped groove is symmetricly set on the both sides of pole; The top described pole being positioned at pressing plate is provided with thread segment, and described thread segment is provided with nut.
When adopting technique scheme, moved downward along pole by rotating nut band dynamic pressure plate, the pipe fitting be placed in V-shaped groove is clamped.Owing to being hinged with two briquettings on pressing plate, compress pipe fitting by briquetting.Even if the pipe fitting be placed in two V-shaped grooves of the same side varies in size, also by the rotation of briquetting around pin joint, can clamp all pipe fittings, in theory, the clamping force suffered by each pipe fitting is equal simultaneously, the problem that there will not be folder bad pipe fitting and can not clamp.
Further, the cross section of described briquetting is obtuse triangle, and described briquetting rotating shaft is positioned at obtuse angle place, and the hypotenuse of described briquetting is downward, and described hypotenuse is provided with pressure head.This setting by the deadweight of briquetting, can make hypotenuse downward, is convenient to clamping.
Further, described nut is provided with two handles, in the angle of 120 ° between described handle.Rotating nut can be carried out by swing handle, play labour-saving effect.
Further, spheric washer is provided with between described nut and pressing plate.This setting can prevent Long Term Contact wearing and tearing between nut and pressing plate, even if spheric washer wearing and tearing, also solves by the mode by changing spheric washer.
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 parallel linking clamping mechanism embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, the parallel linking clamping mechanism of the present invention, comprise base 1, base 1 is fixed with a pole 2, pole 2 is arranged with a pressing plate 3, two briquettings 4 are hinged with below pressing plate 3, briquetting 4 is symmetricly set on the two ends of pole 2, and the cross section of briquetting 4 is obtuse triangle, and the rotating shaft of briquetting 4 is positioned at obtuse angle place, the hypotenuse of briquetting 4 is downward, and hypotenuse is provided with pressure head.This setting by the deadweight of briquetting 4, can make hypotenuse downward, is convenient to clamping.Base 1 offers four V-shaped grooves, V-shaped groove is positioned at immediately below briquetting 4, and V-shaped groove is symmetricly set on the both sides of pole 2; Top pole 2 being positioned at pressing plate 3 is provided with thread segment, and thread segment is provided with nut 5.Nut 5 is provided with two handles, in the angle of 120 ° between two handles.Rotating nut 5 can be carried out by swing handle, play labour-saving effect.Spheric washer 6 is provided with between nut 5 and pressing plate 3.This setting can prevent Long Term Contact wearing and tearing between nut 5 and pressing plate 3, even if spheric washer 6 weares and teares, also solves by the mode by changing spheric washer 6.
In the present invention, be with dynamic pressure plate 3 to move downward along pole 2 by rotating nut 5, the pipe fitting 7 be placed in V-shaped groove is clamped.Owing to being hinged with two briquettings 4 on pressing plate 3, compress pipe fitting 7 by briquetting 4.Even if the pipe fitting 7 be placed in two V-shaped grooves of the same side varies in size, also by briquetting 4 around the rotation of pin joint, all pipe fittings 7 can be clamped, in theory simultaneously, each clamping force suffered by pipe fitting 7 is equal, the problem that there will not be folder bad pipe fitting 7 and can not clamp.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
