Abstract

The utility model discloses an eccentric fixture, which comprises a fixture body which can be connected with a spindle of a machine tool, wherein a mandrel sleeve whose axial cord is deviated away from the rotating axial cord of the fixture body is fixed on the fixture body, one end of the mandrel sleeve is fixedly connected with the fixture body, the other end is extruded from the fixture body and is provided with a stepped cylindrical structure which is capable of packing a work-piece, a draw rod which can be drawn by a cylinder is traversed through the mandrel sleeve, the outer end of the draw rod extends out of the mandrel sleeve and is connected with a work-piece propping mechanism. The eccentric fixture which is designed by the utility model is characterized in that an inner hole on a work-piece is packed by the mandrel sleeve which is eccentrically arranged, and the draw rod which is used for pressing and packing the work-piece is coaxially traversed through the mandrel sleeve, thereby the eccentric mandrel sleeve can eccentrically fix the inner hole of the work-piece, and the axial cord of the work-piece, which needs to be processed with an excircle, can share the same line with the rotating axial cord of the fixture body, thereby the fixture body can coaxially rotate with the rotating shaft of the machine tool, and the cutting can be realized. The eccentric fixture can realize a higher machining efficiency and has higher economic and social benefits after being spread.

Description

A kind of eccentric fixture

Technical field

The utility model relates to the lathe anchor clamps, especially a kind of eccentric fixture.

Background technology

When the processing eccentric element, still generally adopt three-jaw or chuck in the existing machinery processing, because to heart problem, the clamping workpiece difficulty, machining accuracy also is difficult to guarantee, often cause part scrap and processing cost higher, therefore, existing eccentric fixture be unsuitable in enormous quantities, the production of high-precision part.

The utility model content

The purpose of this utility model is to provide the eccentric fixture that a kind of clamping speed is fast, precision is high.

The technical solution of the utility model is: a kind of eccentric fixture, comprise the clamp body that can be connected with lathe spindle, be fixed with the core sleeve of axis runout outside the clamp body pivot center on the described clamp body, core sleeve's one end and clamp body are connected, but the outstanding clamp body of the other end also has the step cylindrical structure of suit workpiece, being equipped with in the core sleeve can be by the pull bar of cylinder pulling, and the pull bar outer end is stretched out core sleeve and is connected with the workpiece top-pressure mechanism.

Described workpiece top-pressure mechanism comprises the platen that is fixed in the pull bar outer end, in being provided with ledge structure near the position of platen, is covered with open washer on the pull bar between the step end face of this ledge structure and platen on the described pull bar.

One end of described clamp body offers the mounting groove that is connected usefulness with lathe spindle.

On the same side end face that core sleeve stretches out, also be provided with the workpiece alignment pin on the described clamp body.

The designed eccentric fixture of the utility model is that the core sleeve by the off-centre setting comes the endoporus on the suit workpiece, and make that the pull bar that press-fits workpiece is coaxial to be arranged in the core sleeve, thereby make the endoporus that eccentric core sleeve can eccentric fixation workpiece, and make workpiece need the axis of processing excircles and the pivot center conllinear of clamp body, thereby make the anchor clamps physical efficiency with the coaxial rotation of lathe rotating shaft, realize cutting; The utility model is easy to install, can with the automatic or supporting use of semi-automatic lathe, can realize higher working (machining) efficiency, have higher economic and social benefit after the popularization.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, anchor clamps of the present utility model comprise the clamp body 10 that can be connected with lathe spindle, clamp body 10 has eccentric pivot hole, one end of clamp body 10 offers the mounting groove 15 that is connected usefulness with lathe spindle, clamp body 10 other ends are fixed with core sleeve 8, one end of core sleeve 8 is inserted in the eccentric pivot hole of clamp body 10, but the outstanding clamp body 10 of the other end also has the step cylindrical structure of suit workpiece 14, be equipped with pull bar 6 in the core sleeve 8, pull bar 6 one ends 4 are connected with connecting rod 2 on rotary cylinder 13 piston rods by helping pull a cart, the other end of pull bar 6 stretches out core sleeve 8 and is fixed with platen 3, in being provided with ledge structure, between the step end face of this ledge structure and platen 3, be covered with open washer 11 on the pull bar 6 on the pull bar 6 near the position of platen 3.Also be provided with workpiece alignment pin 12 on the described clamp body 10 on the same side end face that core sleeve 8 stretches out, workpiece 14 can be by the locating hole of setting on it and cooperating of workpiece alignment pin 12, to improve clamping efficient.After being subjected to rotary cylinder 13 pulling with pull bar 6, can spurring the workpiece 14 that platen 3 will be sleeved in the core sleeve 8 and compress.As shown in Figure 1, pull bar 6, core sleeve 8 are coaxial setting, its axis is A, the central axis of the mounting groove 15 of clamp body 10 is coaxial with the lathe rotating shaft, its axis is B, and core sleeve's 8 off-centre are arranged on the clamp body 10, and the axis of workpiece 14 is overlapped with the pivot center of clamp body 10, thereby make clamp body 10 realize cutting with the coaxial rotation of lathe rotating shaft.

Claims (4)

1, a kind of eccentric fixture, comprise the clamp body that can be connected with lathe spindle, it is characterized in that: be fixed with the core sleeve of axis runout outside the clamp body pivot center on the described clamp body, core sleeve's one end and clamp body are connected, but the outstanding clamp body of the other end also has the step cylindrical structure of suit workpiece, being equipped with in the core sleeve can be by the pull bar of cylinder pulling, and the pull bar outer end is stretched out core sleeve and is connected with the workpiece top-pressure mechanism.
