Description

Technical Field

[0001] The utility model relates to the relevant field of centerless grinders, in particular to a centerless grinder with accurate feeding. Background Art

[0002] Centerless grinders are a type of grinder that does not require the axis of the workpiece to be positioned for grinding. They are mainly composed of three mechanisms: grinding wheel, adjusting wheel and workpiece support. The grinding wheel actually performs the grinding work, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece support supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principle is the same except for stopping grinding.

[0003] In the prior art, a utility model patent with announcement number CN 212351363 U proposes a centerless grinder with accurate feeding. The equipment adopts a cylinder as a driving source through the arrangement of structures such as a swing cylinder, a rotating rod, and a feed block. After the piston rod inside the swing cylinder is extended, the rotating rod rotates, thereby pushing the feed block to deliver the workpiece to the processing station, replacing the traditional complex mechanical arm feeding structure, greatly reducing the manufacturing cost;

[0004] However, it does not have the ability to flush the workpiece and the grinder. During grinding, the workpiece and the grinder are easily affected by dust and high temperature, which reduces the grinding quality and efficiency of the device. At the same time, it does not have the ability to quickly disassemble the grinding components, which is not convenient for subsequent inspection and maintenance of the grinding components. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content
