Mechanism for deburring thrust surface of engine cylinder block and automatically compensating feeding amount of brush

The invention provides a mechanism for automatically compensating for the feeding amount of a brush for deburring of a thrust surface of an engine cylinder body, and belongs to the technical field of automobile engine machining. The problems that deburring equipment for the thrust surface (annular belt surface) of the cylinder body is high in cost and single in purpose, and consumables (brushes) are complex to replace are solved. The mechanism comprises a deburring cutter, a cutter rotation and translation driving mechanism and a lifting mechanism, the deburring cutter is used for deburring the engine cylinder block, the cutter rotation and translation driving mechanism is used for driving the deburring cutter to translate and rotate, and the lifting mechanism is used for lifting the cutter rotation and translation driving mechanism. The device can be compatible with various workpieces (the intervals of the cylinder barrels are the same in size or small in difference) at the same time, the equipment utilizati
