Problems solved by technology

[0002] The traditional mandrel tapered surface locates the workpiece, there is no workpiece ejection device, and it cannot be too tightly matched. After the process is completed, the main body mandrel and the workpiece need to be taken out of the machine tool, and then the workpiece and the main body mandrel are placed on the workbench. Separated, resulting in the defects of low processing efficiency, easy damage to the workpiece, and easy damage to the mandrel; in addition, because the fit cannot be too tight, the friction between the workpiece and the mandrel is not enough to limit the degree of freedom of rotation, so it can only be used for cutting force Smaller cylindrical turning and cylindrical grinding cannot be used for milling the outer contour surface of the workpiece or drilling or boring the end face hole or radial hole of the workpiece

Abstract

The invention belongs to the technical field of mechanical engineering, and particularly discloses a workpiece self-centering elastic removal device. The workpiece self-centering elastic removal device comprises a body mandrel installed on a machine tool, the body mandrel is sequentially provided with an elastic removal pad, a flat gasket and a gland nut, the gland nut is in threaded connection with the body mandrel, a virtual workpiece is installed in a cavity between the elastic removal pad and the flat gasket, and fixing of the virtual workpiece is achieved. Compared with the prior art, theworkpiece self-centering elastic removal device can be installed on machine tools such as a lathe, a milling machine, a machining center and a grinding machine, based on the friction force between the body mandrel and the conical surface of the workpiece as well as the friction force formed between the elastic removal pad and the end surface of the workpiece, the rotational degree of freedom canbe limited, the workpiece self-centering elastic removal device can be widely applied to polyhedron turning, milling, drilling and the like of various parts positioned through a conical surface hole as well as workpiece outline surface milling or workpiece end surface hole drilling or radial hole drilling and machining of other work surfaces, and the workpiece self-centering elastic removal devicehas the advantages of being high in efficiency, precision and reliability and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a workpiece self-centering elastic withdrawal device. Background technique [0002] The traditional mandrel taper surface locates the workpiece, there is no workpiece withdrawal device, and the fit cannot be too tight. After the process is completed, the body mandrel and the workpiece need to be taken out from the machine tool, and then the workpiece and the body mandrel are placed on the worktable. separation, resulting in the defects of low processing efficiency, easy damage to the workpiece, and easy damage to the mandrel; in addition, because the fit cannot be too tight, the friction between the workpiece and the mandrel is not enough to limit the rotational freedom, so it can only be used for cutting force Smaller external turning and external grinding cannot be used for milling the outer contour surface of the workpiece or for drilling and boring the end hole...
