A fixed-size fillet grinding device

Abstract

The invention relates to a fixed-size round corner polishing device. The fixed-size round corner polishing device comprises a polishing machine for polishing a round corner on a workpiece to be polished. The fixed-size round corner polishing device is characterized by further comprising a support, a rotary shaft base and a rocker arm, wherein a workpiece holding base for holding the workpiece to be polished is arranged on one side of the upper portion of the support; the rotary shaft base is fixed to the other side of the upper portion of the support and provided with a rotary shaft capable of rotating around the axis of the rotary shaft, and the axis of the rotary shaft is coaxial with the center of the to-be-polished round corner of the workpiece to be polished; and the front end of the rocker arm is fixed to the rotary shaft, the rocker arm can rotate along with the rotary shaft, and the polishing machine is mounted on the rocker arm and can swing along with the rocker arm. The rocker arm is used for limiting the motion trail of the polishing machine so that the radius of the polished round corner can be controlled accurately. During polishing, the workpiece to be polished is mounted on the workpiece holding base, then the polishing machine is started to slowly get close to the to-be-polished edge of the workpiece, after an abrasive belt makes contact with the workpiece, the rocker arm starts to rotate, polishing is completed after the rocker arm moves along the polishing trail by a circle, and thus simple operation is achieved.

Description

technical field [0001] The invention relates to a fillet grinding device, in particular to a fixed-size fillet grinding device. Background technique [0002] In modern industry, a large number of metal parts need to be ground and rounded. Usually, these grinding processes are freely operated by workers, and one edge needs to be repeatedly ground for many times, and the labor intensity of workers is relatively high. In some assembly situations, the size of the fillet is more stringent, and the fillet radius is too large or too small. The assembly requirements between the installation hole and the shape of the water tank body are relatively high. The outer dimension of the open end of the water tank body is in transition with the installation hole to ensure that the outer periphery of the open end of the water tank body and the inner hole wall of the installation hole fit closely, so as to ensure the water tank. The body and the panel are firmly welded. Before assembly, we wi...
