Abstract

The utility model discloses a fixture for clamping a slender workpiece. The fixture comprises a cylindrical fixture body, wherein the outer wall of the cylindrical fixture body is provided with a step; a straight hole nut and a taper hole nut are threaded on the middle part and the back end of the outer circle of the cylindrical fixture body respectively; the end part of the straight hole nut is provided with an inwardly-contracting conical surface; the inner wall of the front end of the cylindrical fixture body is provided with an inclined step hole; a step pin is arranged in the step hole; the lower end of the step pin is pressed against the conical surface of the end part of the straight hole nut; the back end of the taper hole nut contracts inwardly, and a sealing bottom is formed; the middle part of the sealing bottom is provided with a taper hole and a split chuck; the back end of the split chuck is fixed on the inner wall of the back end of the cylindrical fixture body; the front end of the split chuck passes through the taper hole and extends outwardly; and the front end of the split chuck is provided with a taper surface matched with the taper hole. The fixture has a simple structure, and aligning central lines of the workpiece and the fixture body can be found easily, so that the two ends of the slender workpiece can be clamped conveniently and rapidly, and the working efficiency and the processing precision are greatly increased.

Description

The anchor clamps that are used for the clamping slender piece
Technical field
The utility model relates to a kind of anchor clamps that are used for the clamping slender piece.
Background technology
The function of anchor clamps is to clamp workpiece entering next procedure to be processed to process.On machining, often need process elongated shaft-like workpiece.Owing to thin and long shafts workpiece centring in anchor clamps is very difficult, therefore add to greatly reduce operating efficiency man-hour.
The utility model content
The purpose of the utility model provides a kind of anchor clamps that are used for the clamping slender piece, realizes clamping work pieces easily and fast.
The technical scheme of the utility model is following:
A kind of anchor clamps that are used for the clamping slender piece; Comprise the tubular clamp body; It is characterized in that: be provided with the step that successively decreases successively on the outer wall of said tubular clamp body from front to back, the middle part of tubular clamp body cylindrical and rear end have screwed togather straight hole nut and taper hole nut respectively, and the end of said straight hole nut is provided with the conical surface of inside contraction; The inwall of said tubular clamp body front end is provided with the stepped hole of a plurality of inclinations; Be provided with the step pin in the stepped hole, be provided with spring between the upper end of said step pin and the step surface of stepped hole, the lower end of step pin is against on the conical surface of straight hole nut end;
Inwardly shrink and the formation back cover rear end of said taper hole nut; The middle part of back cover is provided with taper hole; Include the distinguish chuck; The rear end of said distinguish chuck is fixed on the inwall of tubular clamp body rear end, and the front end of distinguish chuck passes described taper hole and stretches out, and the front end of distinguish chuck has the conical surface that matches with said taper hole;
Have workpiece to pass described tubular clamp body backward, the end of said step pin withstands on the outside of workpiece front end in the past, and described distinguish chuck withstands on the outside of workpiece rear end.
The described anchor clamps that are used for the clamping slender piece is characterized in that: the front end outer of said tubular clamp body is equipped with ring flange.
In the time of in workpiece places the tubular clamp body, rotate the taper hole nut, extruding distinguish chuck; Make the distinguish chuck shrink the rear end of clamping workpiece, rotate the straight hole nut, the straight hole nut will promote the elastic force that the step pin overcomes spring; The workpiece front end is lived in extruding, thereby reaches fixing to clamp workpiece.
The beneficial effect of the utility model:
The utility model is simple in structure, is easy to find the centring line of workpiece and clamp body, thereby can grasp the two ends of slender piece easily and fast, thereby has improved operating efficiency and machining accuracy greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1; A kind of anchor clamps that are used for the clamping slender piece comprise tubular clamp body 1, are provided with the step that successively decreases successively on the outer wall of tubular clamp body 1 from front to back; The middle part of tubular clamp body 1 cylindrical and rear end have screwed togather straight hole nut 2 and taper hole nut 3 respectively; The end of straight hole nut 2 is provided with the conical surface of inside contraction, and the inwall of tubular clamp body 1 front end is provided with the stepped hole 9 of a plurality of inclinations, is provided with step pin 4 in the stepped hole 9; Be provided with spring 5 between the step surface of the upper end of step pin 4 and stepped hole 9, the lower end of step pin 4 is against on the conical surface of straight hole nut 2 ends;
Inwardly shrink and formation back cover 5 rear end of taper hole nut 3; The middle part of back cover 5 is provided with taper hole; Include distinguish chuck 6; The rear end of distinguish chuck 6 is fixed on the inwall of tubular clamp body 1 rear end, and the front end of distinguish chuck 6 passes taper hole and stretches out, and the front end of distinguish chuck 6 has the conical surface that matches with taper hole;
Have workpiece 7 to pass tubular clamp body 1 backward, the end of step pin 4 withstands on the outside of workpiece 7 front ends in the past, and distinguish chuck 6 withstands on the outside of workpiece rear end.
Further, the front end outer of tubular clamp body 1 is equipped with ring flange 8.
