Abstract
The utility model relates to a novel self-energizing clamper. Two clamp heads are respectively movably hinged to a clamp body through two pin shafts, The clamp head has an eccentric sector construction, the clamping surface of the clamp head has a cylindrical surface, a circular arc groove surface or a tooth profile surface construction. The self-energizing clamper provided in the utility model has advantages of big clamping force, reliability, wide range of clamping size, convenient operation, simple structure, and low production costs. The utility model can be widely applied in clamping deformed steel, steel pipe, plate and other section steels, and wire rope, anchor and other material drawing samples.
Description
Technical field
The utility model relates to a kind of Civil Engineering Construction, jig and material properties test device, particularly a kind of novel self energizing effort clamper.
Background technology
In civil construction project construction, jig and material property detect, usually need to axle class plate parts, as shaped steel such as screw-thread steel, steel pipe, sheet materials; Steel wire rope and anchor pole, material extending sample etc. carries out the clamping drawing, requires reliable clamping, does not have absent-mindedness.In the engineering, modal clamper is an awl watt formula clamper, and it can strengthen under pulling force automatically to being held the radial pressure of part, thus the clamping of realization self energizing effort.But in actual use, should be noted that each awl placement watt in taper hole, need carry out lubricated preferably to awl watt outer surface, need to select the awl watt clamper of corresponding specification according to the radial dimension that is held part, therefore the reliability of clamping is not high, needs to prepare how secondary clamper to adapt to the part of Different Diameter to dimensions.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel self energizing effort clamper, has clamping reliability height, and is easy and simple to handle to being held the wide adaptability of part radial dimension specification, lower-cost characteristics.
For solving the problems of the technologies described above, the technical scheme that the utility model self energizing effort clamper is taked is: a kind of novel self energizing effort clamper, two chucks are movably hinged by two bearing pins and clamp body respectively.
Chuck be eccentric fan structure.
The circular arc clamping face of chuck is the face of cylinder, circular arc groove face or tooth-shape structure.
The beneficial effect of the utility model self energizing effort clamper is as follows:
1, realizes that by two eccentric clampings symmetry clamps, and form the clamping effect of self energizing effort;
2, be held part radially or the gauge scope big, do not need clamper is done any adjustment;
3, clamping, unclamp easily, simple in structure, cost is lower.
Description of drawings
Fig. 1 is the utility model apparatus structure schematic diagram.
The specific embodiment
A kind of novel self energizing effort clamper, two chucks 3,3 ' flexibly connect by two bearing pins 2,2 ' and clamp body 1 respectively.
Described chuck 3,3 ' be eccentric fan structure.
The circular arc clamping face of described chuck 3,3 ' is the face of cylinder, circular arc groove face or toothed surface structure.
Operation principle:
According to two eccentric principles that clamp, chuck 3,3 ' clamping face can be processed circumferential arc surface, and can be chosen in arc surface bottom design tooth-shape structure, to increase chuck 3,3 ' and the contact area that is held part 4, reduce specific pressure, reduce the distortion that is held part 4, but can increase the frictional force of clamping.During clamping, only need be close to two chucks, 3,3 ' symmetry in the both sides that are held part 4 and get final product.During drawing, at chuck 3,3 ' and the frictional force of 4 of parts drive down, the deflection in opposite directions of two chucks, 3,3 ' trace will be held part 4 automatically and clamp, and along with the increase of pulling capacity, chuck 3,3 ' clamping force also increases thereupon, forms the effect of self energizing effort.
