Abstract
The invention discloses a clamp for an elongated workpiece. The clamp comprises a clamp body [4], a straight hole nut [1], a taper hole nut [2] and a split clamp head [3], wherein the clamp body [4] is formed by connecting three cylinders with different diameters; a through hole is formed in the center of the clamp body; threads are formed outside the cylinders; the taper hole nut [2] and the straight hole nut [1] are connected to the threads; the straight hole nut is provided with an inclined surface [6]; the taper hole nut [2] is provided with a bottom seal; the bottom seal is provided with a taper hole; the split clamp head [3] is positioned in a through hole of the cylinder with smaller diameter of the clamp body [4] and is matched with the taper hole of the taper hole nut [2]; a connection part of the cylinder at the end with larger diameter and the middle cylinder is provided with a stepped hole in which a stepped pin [5] is arranged; the lower part of the stepped pin is provided with a spring [7]; and one end of the stepped pin is pressed against the inclined surface [6] of the straight hole nut [1]. Through the clamp, the elongated workpiece can be conveniently clamped, so that the labor efficiency and the production efficiency are greatly improved.
Description
Technical field
The present invention relates to a kind of anchor clamps of fixation workpiece, especially the anchor clamps of elongate workpiece.
Background technology
The function of anchor clamps is to clamp workpiece to be processed to enter next procedure and process.On machining, often need process elongated shaft-like workpiece.Because thin and long shafts workpiece centring in anchor clamps is very difficult, therefore adds and greatly reduce efficiency man-hour.
Summary of the invention
Purpose of the present invention just provides a kind of anchor clamps of elongate workpiece, and convenient the realization fast clamps, and raises labour efficiency greatly.
The technical solution used in the present invention is: a kind of slender piece anchor clamps, it is characterized in that it comprises clamp body, straight hole nut, taper hole nut and distinguish chuck, described clamp body is the continuous formations of three different-diameter cylinders, the center of clamp body is provided with and is used for the through hole of clamping work pieces, diameter is provided with screw thread than the periphery of small column and intermediate cylindrical, taper hole nut and straight hole nut connect with two cylindrical threads respectively, and described straight hole nut end face is provided with the inclined-plane; Described taper hole nut is that nut end face is provided with back cover, and back cover is provided with taper hole; The distinguish chuck is positioned at the less cylindrical hole of clamp body diameter, and the end is stretched out through hole and matched with the taper hole of taper hole nut, makes extruding distinguish chuck end when the taper hole nut moves; The double-screw bolt of straight bigger end is provided with the stepped hole that several communicate with the inclination of clamp body central through hole with middle double-screw bolt connecting portion, be provided with the step pin suitable in the stepped hole with stepped hole, be provided with spring between the bottom of step pin and the step surface of stepped hole, an end of step pin is squeezed on the inclined-plane of straight hole nut.
Adopt technique scheme, in the time of in workpiece places the clamp body central through hole, rotate the taper hole nut, extruding distinguish chuck makes the distinguish chuck shrink the afterbody of clamping workpiece.Rotate the straight hole nut, the straight hole nut will promote the elastic force that the step pin overcomes spring, and the workpiece front portion is lived in extruding, thereby reaches fixing to clamp workpiece.
Beneficial effect of the present invention is: because two ends of the present invention can conveniently clamp the two ends of slender piece, so the elongate workpiece is simple and convenient rapidly, and the centring line is easy, thereby has improved labor productivity greatly.
