Abstract
The utility model discloses a kind of fine-tuning clamping force fixture, belong to machining apparatus field, comprise connecting rod, lever arm, grip block, nut and rotating shaft; One end of described connecting rod is free end, and the other end of described connecting rod connects two described lever arms; Described lever arm is rotationally connected by described rotating shaft and described connecting rod; The other end of two described lever arms is fixedly connected with a described grip block respectively; Two described lever arms are provided with screw thread; Described connecting rod is provided with one section of screw thread equally on the position of described rotating shaft, described nut with on described connecting rod described in be threaded; Described nut simultaneously with the described threaded engagement on described lever arm, the adjustment of clamping force is carried out by nut and helicitic texture, nut is every precession or a back-out fillet of screw on lever arm, just can realize trickle adjustment to clamping force, and nut power need not maintain by the extra energy such as hydraulic pressure and electric energy, energy-conserving and environment-protective.
Description
Technical field
The utility model relates to a kind of machining apparatus, particularly relates to a kind of fine-tuning clamping force fixture.
Background technology
Fixture refers in machine-building process and is used for fixing processing object, makes it to occupy correct position, to accept the device of constructing or detecting, also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed (location) before processing, clip (clamping).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).In prior art, fixture is a kind of requisite instrument in machining, and its structure is various.Clamping force source mainly contains hydraulic cylinder, cylinder, electrodynamic source etc.The adjustability of the clamping force of these fixtures is poor, can not finely tune according to the demand of product.The power source energy consumption that fixture described in addition adopts is large, not energy-conservation also not environmentally.
Summary of the invention
The purpose of this utility model is just to provide that a kind of clamping force adjustability is good, the fixture of energy-conserving and environment-protective to be to solve the problem.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of fine-tuning clamping force fixture, comprises connecting rod, lever arm, grip block, nut and rotating shaft; One end of described connecting rod is free end, and the other end of described connecting rod connects two described lever arms; Described lever arm is rotationally connected by described rotating shaft and described connecting rod; The other end of two described lever arms is fixedly connected with a described grip block respectively; Two described lever arms are provided with screw thread; Described connecting rod is provided with one section of screw thread equally on the position of described rotating shaft, described nut with on described connecting rod described in be threaded; Described nut simultaneously with the described threaded engagement on described lever arm.
During use, connecting rod free end, for being fixed on processing equipment, the adjustment of clamping force is carried out by nut and helicitic texture, nut is every precession or a back-out fillet of screw on lever arm, just can realize trickle adjustment to clamping force, and nut power need not maintain by the extra energy such as hydraulic pressure and electric energy.
The pitch of screw thread, can select different sizes according to the difference of processing object, to adapt to the needs of finely tuning.
As preferred technical scheme: the clamping face of described grip block is provided with flexible pad.Flexible pad structure can better protect product not to be scraped off.
As preferred technical scheme: described flexible pad is rubber blanket.
Compared with prior art, the utility model has the advantage of: the adjustment being carried out clamping force by nut and helicitic texture, nut is every precession or a back-out fillet of screw on lever arm, just can realize trickle adjustment to clamping force, and nut power need not maintain by the extra energy such as hydraulic pressure and electric energy, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, connecting rod; 2, lever arm; 3, grip block; 4, nut; 5, rotating shaft; 6, screw thread; 7, rubber blanket.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: see Fig. 1, a kind of fine-tuning clamping force fixture, comprises connecting rod 1, lever arm 2, grip block 3, nut 4 and rotating shaft 6; One end of connecting rod 1 is free end, and this free end is for being fixed on processing equipment, and the other end of connecting rod 1 connects two lever arms 2; Lever arm 2 is rotationally connected by rotating shaft 5 and connecting rod 1; The other end of two lever arms 2 is fixedly connected with a grip block 3 respectively; Two lever arms 2 are provided with screw thread 6; Connecting rod 1 is provided with one section of screw thread 6 equally on the position of rotating shaft 5, and nut 4 is connected with the screw thread 6 on connecting rod 1; Nut 4 coordinates with the screw thread 6 on lever arm 2 simultaneously; Nut 4 is for regulating the clamping force of two lever arms 2 along the screw thread 6 on lever arm 2 to grip block 3 precession or back-out;
In the present embodiment, the clamping face of grip block 3 is provided with rubber blanket 7, can better protect product not to be scraped off.
