[0002] The end face parallel grinding chamfering machine is a key equipment specially used for high-precision metal workpiece end face chamfering and deburring, which carries out precision grinding on the workpiece end face through high-speed rotating grinding wheel or grinding disc, and is widely applied to automobile engine cylinder body, precision bearing, hydraulic valve core and other machining scenes with extremely high requirements for end face parallelism (less than or equal to 0.01mm), surface roughness (Ra less than or equal to 0.8um) and chamfer size consistency. The contact area of the grinding wheel and the workpiece is large and the grinding force is uniformly distributed during the end face grinding process, which can effectively avoid the edge collapse or material stress concentration problems easily occurring in the traditional cutting process, and is especially suitable for machining of high-hardness workpieces such as quenched steel and ceramic composite materials.

[0003] In actual batch production, the machining quality and efficiency of the end face parallel grinding chamfering machine highly depend on the precision and stability of the workpiece feeding system. However, when multiple workpieces enter the grinding area at the same time, the contact pressure of the grinding wheel and the workpiece is unevenly distributed due to the position deviation or size tolerance of the workpieces, which can accelerate the local wear of the grinding wheel, and also can cause the inconsistent chamfer width of the workpiece end face or the surface waviness exceeding the standard, and in severe cases, can even cause the grinding wheel to break or the workpiece to be scrapped.

[0004] In view of the above problems, a new type of feed limiting device capable of controlling the feed quantity and size adaptability of the workpiece is needed to solve the contradiction between quality and efficiency caused by synchronous machining of multiple workpieces. INVENTION CONTENTS
