Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a feeding device for a centerless grinder. Background Art

[0002] A centerless grinder is a type of grinder that does not require the use of the workpiece's axial positioning for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting guide wheel, and a workpiece support wheel. The grinding wheel is actually responsible for grinding, the adjusting guide wheel controls the rotation of the workpiece, and the workpiece support wheel supports the workpiece during grinding. These three parts can be coordinated in several ways. Generally, the workpiece on the workpiece support wheel is ground by adjusting the relative displacement of the grinding wheel and the adjusting guide wheel, but the principle is roughly the same except for stopping grinding.

[0003] After searching, the utility model patent with announcement number CN218194143U discloses a feeding device for a centerless grinder, including a grinding wheel, an adjusting guide wheel and a workpiece support wheel arranged below the grinding wheel and the adjusting guide wheel for supporting a circular tubular workpiece, a mounting frame is provided on one side of the workpiece support wheel, a V-shaped support plate is installed on the upper side of the mounting frame, the V-shaped support plate is horizontally arranged on one side of the workpiece support wheel, and the circular tubular workpiece can be placed on the upper side of the V-shaped support plate. This patent can pre-place the circular tubular workpiece by providing a V-shaped support plate on one side of the workpiece support wheel, the V-shaped support plate is provided with a Y-shaped support plate, and the Y-shaped support plate is driven to move by a feeding push mechanism to push the circular tubular workpiece to the workpiece support wheel for grinding. It is simple and convenient to use, and its work efficiency is greatly improved. At the same time, it avoids users from being close to the grinding equipment, which is beneficial to reducing safety hazards.

[0004] However, the above patent still has the following shortcomings: in actual use, the staff needs to send the workpieces to be polished to the pallet one by one for polishing, which is not convenient. Therefore, we propose a feeding device for the centerless grinder. Utility Model Content
