Abstract

The invention relates to a double-eccentric sanding mechanism of a sanding machine, comprising a motor (1), a fan blade (2), a flange (5) and a working bottom plate (10) with a grinding piece at the bottom surface, wherein the fan blade (2) is sheathed on a main shaft of the motor (1); the flange (5) is fixedly connected with the working bottom plate (10); the double-eccentric sanding mechanism further comprises an eccentric block (3) and a bearing (6); the eccentric block (3) is sheathed on the fan blade (2); the matching position of the fan blade (2) and the eccentric block (3) is provided with a stopping block (2-1) for stopping the rotation of the eccentric block (3); the flange (5) is in interference fit with the excircle of the bearing (6); the incircle of the bearing (6) is sheathed on the eccentric block (3) and is fixedly connected with the eccentric block (3); and the fan blade (2) is provided with an eccentric column (2-2) which is provided with a shaft hole matched with the main shaft of the motor (1). In the double-eccentric sanding mechanism, the swinging amplitude of the working bottom plate can be adjusted according to the requirements, so that the sanding efficiency of the sanding machine is greatly improved.

Description

technical field [0001] The invention relates to the field of sanding machines, in particular to a double eccentric sanding mechanism of the sanding machine. Background technique [0002] At present, the commonly used sanding machine uses a motor to drive the working base plate with sandpaper on the working surface to rotate to sand the workpiece. The disadvantage of this structure is that the working base plate cannot adjust its swing range, its working stroke is small, and its working efficiency is low. Chinese patent CN201151080Y discloses a sander. By setting an eccentric bushing on the motor shaft, the working bottom plate can also swing during rotation. However, the swing amplitude of this structure cannot be adjusted, and the work efficiency is limited. Contents of the invention [0003] The object of the present invention is to provide a double eccentric sanding mechanism of a sanding machine with adjustable swing range of the working base plate and high sanding ef...
