Hinge polishing equipment and polishing method

Abstract

The invention provides hinge leaf polishing equipment and method, and the hinge leaf polishing equipment is simple in structure and low in cost. The hinge leaf polishing equipment comprises a rack. A guide rail and a workbench are arranged on the rack. The workbench is movably erected on the guide rail. The rack is provided with a driving mechanism used for driving the workbench to move along the guide rail. A polishing wheel capable of ascending and descending is arranged on the portion, above one side of the guide rail, of the rack. The hinge leaf polishing equipment is characterized in that a limiting groove is formed in the top face of the workbench; the end, close to the polishing wheel, of the limiting groove is closed; the two sides of the limiting groove are provided with arc-shaped grooves matched with hinge leaf rotary shaft sleeves; and the hinge leaf polishing equipment further comprises the rotary shaft sleeves penetrating through hinge leaves, and fixing rods used for fixing the hinge leaves. By the adoption of a limiting mode of the limiting groove, the arc-shaped grooves and the fixing rods, the hinge leaves can be fixed quite conveniently and stably, polishing is more uniform, and the polishing effect is improved; and in addition, due to the fact that the multiple hinge leaves are polished at the same time, the working efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and specifically relates to a hinge piece polishing equipment and a polishing method. Background technique [0002] The hinge is formed by connecting two hinges through a rotating shaft. The hinge includes a rotating shaft sleeve and a flat plate on one side of the rotating shaft sleeve. The flat plate is provided with a through hole for fixing the hinge. After the hinge is punched out, there will be burrs or scratches on the surface, which will affect the use and appearance, so it needs to be polished by polishing equipment. However, due to the small size of the hinge piece and the lack of a suitable fixing mechanism to fix it, it is difficult to ensure the uniformity and effect of polishing. [0003] The utility model of the patent application number 201410398039.3 discloses a polishing machine for polishing hinges. It uses a non-magnetic metal conveyor belt to place and transport the h...

However, due to the small size of the hinge piece and the lack of a suitable fixing mechanism to fix it, it is difficult to ensure the uniformity and effect of polishing

[0003] The utility model with the patent application number 201410398039.3 discloses a polishing machine for polishing hinges. It uses a non-magnetic metal conveyor belt to place and transport the hinges to be polished. Groove, the depth of the accommodating groove is greater than 2 / 3 of the thickness of the workpiece and less than the thickness of the workpiece; this kind of hinge fixing method needs to process a precise conveyor belt, and the fixing effect is poor
