Small multifunction belt sander

Abstract

The invention discloses a small multifunction belt sander which comprises a sander body portion, a power portion, a roll shaft adjusting mechanism, a workpiece clamping mechanism, a sanding belt tensioning mechanism, a dedusting device and an electrical control system. A roll shaft in the roll shaft adjusting mechanism is arranged at one end of a roll shaft frame through a pair of bearings and a pair of adjusting screw assemblies, and the other end of the roll shaft frame is in a floating connection with a box; an adjusting bolt is arranged at the outer end of the inner side of the roll shaft frame, and the outer end is close to the roll shaft; two locking handles are vertically arranged at intervals, and inner ends of the two locking handles and a semicircle shaft fixed on the inner side of the middle of the roll shaft frame form a thread connection; and a zero line is marked on one side surface of the roll shaft frame to be matched with a vertical ruler on the box to be adjusted for using. According to the small multifunction belt sander, arc-shaped surfaces with various radians and angles can be ground at the end of a round metal tube or a rod in a molding mode, plate type metal workpiece plane can be ground, metal workpiece chamfering deburring processing is performed, the operation is convenient, fast, safe and environment-friendly, the positioning adjustment and grinding accuracies are high, labor intensity is low, working efficiencies are high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of abrasive belt grinding equipment, in particular to a small multifunctional abrasive belt machine. Background technique [0002] (1) At present, the arc-shaped surface at the end of the metal tube or bar is mainly used for combined welding between two round tubes or bars; the above-mentioned arc-shaped surface is generally milled by a milling machine, so the machining accuracy is low. The work efficiency is too low and the cost is high. [0003] (2) At present, the plane of the flat metal workpiece is ground by a surface grinder, so the work efficiency is too low and the grinding cost is high. [0004] (3) At present, the chamfering and deburring treatment of workpieces such as metal round pipes: manual processing is carried out on a grinder, so the labor intensity is high, and the operation is inconvenient and unsafe. [0005] In short, so far there is no one that can complete the above three processing...

[0002] (1) At present, the arc-shaped surface at the end of the metal tube or bar is mainly used for combined welding between two round tubes or bars; the above-mentioned arc-shaped surface is generally milled by a milling machine, so the machining accuracy is low. Work efficiency is too low and cost is high

[0003] (2) At present, the plane of the flat metal workpiece: the surface grinder is used for grinding, so the work efficiency is too low and the grinding cost is high

[0004] (3) At present, the chamfering and deburring of workpieces such as metal round pipes: manual processing is performed on a grinder, so the labor intensity is high, and the operation is inconvenient and unsafe.

[0005] In short, so far there is no one that can complete the above three processing tasks at the same time, that is, forming and grinding arc-shaped surfaces with various radians and angles on the end of metal round tubes or bars, and used for grinding flat metal A small multifunctional abrasive belt machine for the plane of the workpiece and the chamfering and deburring of metal workpieces
