Rotary grinder

Abstract

The invention provides a rotary grinder capable of solving the technical problems that an existing grinder is poor in grinding and deburring effect and the like. The rotary grinder comprises a frame and is characterized in that a rotary rack is rotationally arranged inside the frame; a grinding box I and a grinding box II are symmetrically arranged on the rotary rack; during a rotation process, the grinding box I and the grinding box II do not rotate, so the deburring effect of a grinded part in each box body is improved. The rotary grinder provided by the invention has the advantage of good grinding and deburring effect.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a grinder, in particular to a rotary grinder. Background technique [0002] In the field of mechanical processing and manufacturing, the surface of some metal parts obtained by material removal processing or non-material removal processing methods often has burrs, such as castings, turning parts and stamping parts, etc. In order to remove burrs, metal parts are usually placed on a grinding machine The traditional grinder includes a rotatable barrel, put the metal parts into the barrel, and then add the abrasive, and the metal parts and the abrasive are rubbed by the rotation of the barrel to achieve the purpose of deburring. During the grinding process, since the barrel is rotating, when it rotates around the axis of the barrel at high speed, the metal parts in the barrel are easy to move synchronously with the inner wall of the barrel under the action of centrifugal force, so th...

[0002] In the field of mechanical processing and manufacturing, the surface of some metal parts obtained by material removal processing or non-material removal processing methods often has burrs, such as castings, turning parts and stamping parts, etc. In order to remove burrs, metal parts are usually placed on a grinding machine The traditional grinder includes a rotatable barrel, put the metal parts into the barrel, and then add the abrasive, and the metal parts and the abrasive are rubbed by the rotation of the barrel to achieve the purpose of deburring. During the grinding process, since the barrel is rotating, when it rotates around the axis of the barrel at high speed, the metal parts in the barrel are easy to move synchronously with the inner wall of the barrel under the action of centrifugal force, so that the metal parts and The relative friction between the metal parts and the abrasive becomes worse, which reduces the effect of grinding and deburring. This problem exists no matter whether the barrel is a vertical grinder or a horizontal grinder.
