Floating support applied to grinding machine

The invention discloses a floating support applied to a grinding machine, and relates to the technical field of bearing machining. The floating support comprises a first supporting assembly located below a part to be machined and a second supporting assembly located on the left side or the right side of the part to be machined, and the first supporting assembly and the second supporting assembly have the same structures. The second supporting assembly comprises a supporting rod and a supporting head arranged at the inner end of the supporting rod, and the middle of the supporting head is hinged to the inner end of the supporting rod. The inner side face of the supporting head is symmetrically provided with supporting bevels regarding the center line of the supporting rod, and the two supporting bevels form a concave structure together. Each supporting bevel is fixedly provided with a supporting block. The floating support can find the machining center of the part automatically, the efficiency of equipment adj
