Description

Self-centering elastic withdrawing device for workpiece

Technical Field

The utility model relates to a mechanical engineering technical field specifically is a work piece is from centering elasticity withdrawing device.

Background

The traditional mandrel conical surface positioning workpiece has no workpiece withdrawing device and cannot be matched too tightly, after the working procedure is finished, the body mandrel and the workpiece are taken out of a machine tool together, and then the workpiece and the body mandrel are separated on a workbench, so that the defects of low machining efficiency, easiness in damaging the workpiece and easiness in damaging the mandrel exist; in addition, the friction force between the workpiece and the mandrel is not enough to limit the degree of freedom of rotation due to the fact that the fit cannot be too tight, so that the cylindrical milling tool can only be used for cylindrical turning and cylindrical grinding with small cutting force, and cannot be used for milling the outer contour surface of the workpiece or drilling and boring end surface holes or radial holes of the workpiece.

For solving the problem of complaining about existence, the utility model provides a work piece is from centering elasticity withdrawing device relies on frictional force and elasticity between the body dabber and the work piece conical surface to move back from the frictional force that fills up and work piece terminal surface formed, can restrict rotatory degree of freedom, the mountable is on lathe, milling machine, machining center, lathe such as grinding machine, can mill the processing of working faces such as work piece outer contour face or drilling work piece terminal surface hole or radial hole, have high efficiency, high accuracy, high reliability, the advantage of simple operation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a work piece is from centering elasticity exit device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a work piece is from centering elasticity withdrawing device, is including installing the body dabber on the lathe, the body dabber is equipped with elasticity in proper order and moves back from pad, flat gasket and gland nut, and gland nut and body dabber threaded connection install virtual work piece in elasticity moves back the cavity between pad and the flat gasket, realize virtual work piece's fixed.

As an optimized technical scheme of the utility model, elasticity moves back to fill up for the rubber cushion or establish spring unit's cushion in.

As an optimal technical scheme of the utility model, the body dabber is "T" type structure, and this "T" type structure divide into thick tip and thin tip, thin tip divide into the cover again and establishes elasticity and move back from the conical shaft and the threaded connection gland nut screw spindle of filling up, virtual work piece and flat gasket, conical shaft and screw spindle integrated into one piece.

An operation method of a self-centering elastic ejection device for workpieces comprises the following steps:

s1, mounting the body mandrel on a machine tool, then sequentially mounting an elastic separating pad, a virtual workpiece, a flat gasket and a compression nut, fixing the position of the virtual workpiece, and enabling the virtual workpiece to enter a processed state;

and S2, after the virtual workpiece is machined, keeping the body mandrel fixed on the machine tool, sequentially loosening the compression nuts by an operator, taking out the flat gaskets, and automatically ejecting the virtual workpiece out by the elastic backing pads under the action of the elastic force of the elastic backing pads, so that the machining is finished.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a work piece is from centering elasticity withdrawing device, the mountable is at the lathe, the milling machine, machining center, on the lathe such as grinding machine, rely on frictional force and elasticity between body dabber and the work piece conical surface to move back the frictional force that fills up and work piece terminal surface formed, can restrict rotatory degree of freedom, but wide application in the polyhedron turning with the various parts of conical surface hole location, mill, processing such as drilling and mill the processing of working face such as work piece outer contour face or drilling work piece terminal surface hole or radial hole, high efficiency has, high accuracy, high reliability, the advantage of simple operation.
