Circular saw blade profile centerless grinding machine and method for centerless grinding circular saw blade profile

Abstract

The invention relates to a grinding machine, in particular to a circular saw blade flank center-less grinding machine and the method thereof to centre-less grinding of the circular saw blade flank. A saw blade feeding operating platform which can be moved from side to side is arranged on one side at the upper part of the machine seat of the grinding machine, a saw blade supporting bracket is arranged on the operating platform, a core axle for suspending the saw blade is arranged on the saw blade supporting bracket, a driving wheel and a motor which rotate with the blade with in a fricative way are installed on the two sides of the saw blade on the operating platform; an abrasion wheel and a back wheel which are provided with independent driving motors and respectively arranged on the both side of the saw blade are installed on the other side of the upper part of the machine seat side by side, axial lines of the two wheels are paralleled, and kept parallel with the plane of the saw blade, the rotating speed of the back is lower than the rotating speed of the abrasion wheel, and clearance which can be grinded, adjusted, and installed into the saw blade is arranged between the two wheels. The invention extends the rod center-less grinding principle, the double side grinding can be finished through a double-face alternate grinding method, and clamped and fixed through the floating of the saw blade, on the basis of ensuring the processing efficiency and processing precision, the production cost can be saved, the energy consumption can be saved, and the processing cot of the saw blade can be decreased.

Description

Technical field: [0001] The invention relates to a grinder, in particular to a centerless grinder for the side of a circular saw blade and a centerless grinding method for the side of the circular saw blade. Background technique: [0002] The metal circular saw blade is a disc with a large diameter-to-thickness ratio. In order to ensure the performance and improve the appearance quality, both sides of it must be ground, and the precision level is high. At present, in the grinding process of circular saw blades, the equipment usually used is a vertical axis circular table surface grinder or a horizontal axis circular table surface grinder. Their common feature is that the saw blade is sucked tightly on the electromagnetic chuck, and the suction cup can drive the saw blade to rotate together. Movement, the grinding head uses the end face or circumference of the large-diameter disc grinding wheel for grinding, as the grinding head moves up and down, left and right, it can grind...
