Small table type belt sander

Abstract

The invention discloses a small table type belt sander. The device comprises a positioning shaft, a rotating seat, a fixing plate, an angle adjusting seat, an abrasive belt supporting plate, a graphite plate, an upper driven shaft, a lower driven shaft, an upper driven wheel, a lower driven wheel, a workbench, a tensioning frame, a tensioning wheel, an air spring, a deviation adjusting plate, a tensioning shaft, a speed adjusting motor, a motor controller, a driving wheel, a driving wheel protective cover, a small protective cover, an abrasive belt, a workbench support, a deviation adjusting handle, an elastic positioning pin and a pin shaft. And a locking handle. And the rotating seat changes the angle to change the angle of the whole machine body to realize inclined angle grinding. An arc-shaped groove is formed in the angle adjusting base, the angle of the angle adjusting base is changed, and grinding of workpieces at different angles is achieved. The working table is fixed on the working table support through a pin shaft, the working table can rotate, a kidney-shaped groove is formed in the working table support, and the gap between the working table and the abrasive belt is adjusted. The adjustable-speed motor can adjust different rotating speeds and change the linear speed of the abrasive belt according to the grinding requirements of workpieces, and is small in size, light in weight and convenient to carry.

Description

technical field [0001] The invention relates to a small desktop sand belt machine, which is applied to material surface grinding and polishing. Background technique [0002] The traditional abrasive belt machine is relatively large in size, inconvenient to move and carry, the workbench cannot be turned over, and the angle cannot be adjusted during the grinding process, which cannot meet the grinding needs of workpieces with different angles. cutting needs. Contents of the invention [0003] The invention adopts an adjustable rotating seat, which can be turned over. The workbench can be turned over and the angle adjusted according to needs, and the grinding and polishing of workpieces with different angles can be realized. The motor adopts an adjustable speed motor, and the speed of the abrasive belt can be adjusted according to needs. Light in weight, it solves the problems of single function, inconvenient adjustment, inconvenient movement and carrying during the use of t...
