Description

Technical Field

[0001] This utility model relates to the field of processing auxiliary tools, and in particular to a grinding fixture for processing centerless grinding blades. Background Technology

[0002] The function of the centerless grinder's support plate is to support the workpiece and guide its rotation, ensuring its stability during grinding. The support plate, through its tilt angle and cooperation with the adjusting wheel, fixes the workpiece on the equipment, preventing dimensional errors caused by positional deviations during grinding. The offset design of the support plate's centerline from the adjusting wheel allows the workpiece to rotate between the grinding wheel and the adjusting wheel, ensuring the accuracy of the grinding trajectory. The height of the support plate directly affects the contact position between the workpiece and the grinding wheel; too high may cause workpiece wobbling, while too low may affect the roundness after grinding. Centerless grinders are suitable for through grinding of cylindrical, ring-shaped, and tubular parts. When used with a grinding wheel and adjusting wheel, a centerless grinder can achieve precision grinding of complex contours such as outer diameters and inner holes.

[0003] After wear, the surface of the centerless grinding tool plate will be concave, which will affect the roundness of the workpiece. If the worn tool plate is replaced directly, the loss will be too great. Therefore, the worn tool plate is usually ground flat again before being used again.

[0004] Traditional grinding fixtures for centerless grinding blade support processing have been found to have shortcomings in use. They cannot achieve automatic material replenishment and feeding of the centerless grinding blade support, resulting in low grinding efficiency. Therefore, it is necessary to optimize and improve the traditional grinding fixtures for centerless grinding blade support processing. Summary of the Invention
