Abstract
The utility model discloses a double-circular arc clamp, which is formed in such a manner that a circular arc-shaped groove is formed on the gripping surface of the clamp, and a rectangular groove isformed below the circular arc-shaped groove to divide the circular arc-shaped groove into two circular arcs. Under the equivalent gripping force, the utility model can reduce enormously the deformation of a workpiece and the clamp, thereby improving the gripping accuracy and prolonging the service life of the clamp.
Description
Technical field
The utility model relates to two circular arc anchor clamps that a kind of field of machining is used.
Background technology
In the tradition V-arrangement anchor clamps, what contact with cylindrical workpiece is a plane, is located under the effect of power P, and the radially micro-strain amount that produces between cylindrical workpiece and anchor clamps contact plane is d, its contact position will be the face contact of b by original line contact becoming width, and its contact width b is
The utility model adopts two circular arc anchor clamps, and under similarity condition, contact width radian greatly improves.The raising of contact width can improve the clamping rigidity of anchor clamps greatly, carries bigger chucking power; And under same chucking power, can significantly reduce the distortion of workpiece and anchor clamps, and improve the clamping precision, prolong anchor clamps service life.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pair of circular arc anchor clamps.
The utility model is achieved in that being shaped as of described in the utility model pair of circular arc anchor clamps: a circular groove is arranged on the clamping face of anchor clamps, there is a rectangular recess below of circular groove, two circular arcs about circular groove is divided into are formed two circular arc anchor clamps.
In the tradition V-arrangement anchor clamps, what contact with cylindrical workpiece is a plane, is located under the effect of power P, and the radially micro-strain amount that produces between cylindrical workpiece and anchor clamps contact plane is d, its contact position will be the face contact of b by original line contact becoming width, and its contact width b is
For described in the utility model pair of circular arc anchor clamps, the radius of its arc surface can be 1.1-1.05 workpiece radius doubly.Under similarity condition, the radius R of establishing the anchor clamps arc surface is 1.1r (r is a workpiece radius), and promptly the radius R of anchor clamps arc surface is 1.1 times workpiece radius r, and contact width b at this moment is
Contact width is brought up to 3.32 times of V-arrangement anchor clamps; If R is 1.05r, contact width will become
Contact width is brought up to 6.48 times of V-arrangement anchor clamps.Along with the raising of its contact width and contact area, can improve the clamping rigidity of anchor clamps greatly, carry bigger chucking power; And under same chucking power, can significantly reduce the distortion of workpiece and anchor clamps, and improve the clamping precision, prolong anchor clamps service life.
The radius R of two arc surfaces can be got different workpiece radius ratio according to use occasion and environment different in this patent anchor clamps, and for the occasion of no specific (special) requirements, R can get 1.05r or bigger value; For high accuracy or high rigidity occasion, R can get 1.05r or littler value.But littler R can bring the raising of requirement on machining accuracy, the raising of manufacturing cost and the reduction of operation ease.
The utlity model has following beneficial effect: under same chucking power, can significantly reduce the distortion of workpiece and anchor clamps, improve the clamping precision, prolong anchor clamps service life.
Description of drawings
Fig. 1 is a described in the utility model pair of circular arc anchor clamps schematic diagram.
Fig. 2 is traditional V-arrangement anchor clamps schematic diagram.
The specific embodiment
As shown in Figure 1, being shaped as of described pair of circular arc anchor clamps of present embodiment: a circular groove is arranged on the clamping face of anchor clamps, and there is a rectangular recess below of circular groove, and two circular arcs about circular groove is divided into are formed two circular arc anchor clamps.The radius R of anchor clamps arc surface is 1.1r, and contact width b at this moment is
Contact width can be brought up to 3.32 times of V-arrangement anchor clamps.
Claims (2)
