Flexible tool used for grinding and grinding method

Abstract

The invention belongs to a clamping method of mechanical grinding machine machining and particularly relates to a flexible tool used for grinding and a grinding method. The flexible tool used for grinding and the grinding method are suitable for performing grinding on the plane portion of parts easy to deform. Bearing inner and outer ring matched rings belong to thin-walled parts, and are easy to deform and high in planeness and parallelism requirement. The flexible tool comprises a magnetic attracting workbench, and further comprises a flexible standard block, a first fixed standard block and a second fixed standard block; supporting is provided for the parts on the magnetic attracting workbench through the flexible standard block, the first fixed standard block and the second fixed standard block; the flexible stand block comprises an upper movable cushion block and a lower cushion block base; the upper movable cushion block and the lower cushion block base are made from a high magnetism conductivity material, and an inclined sliding matched face is arranged between the upper movable cushion block and the lower cushion block base; an upward force along the sliding matched face is provided for the movable cushion block through a compression spring; and the movable cushion block moves downwards along the sliding matched face under the gravity G of the parts. The parallelism and planeness precision during part grinding is improved.

Description

technical field [0001] The invention belongs to a clamping method for mechanical grinding machine processing, in particular to a flexible tooling for grinding and a grinding method, which is suitable for grinding the plane part of variable parts. Background technique [0002] The mating ring of the inner and outer rings of the autoclinometer bearing is the key load-bearing moving part of the autoclinometer, and its processing quality is directly related to the flight safety of the aircraft. The matching ring of the inner and outer rings of the bearing is a thin-walled part, which is easily deformed and requires high flatness and parallelism. For the specific structure, see figure 1 , The fitting ring of the outer ring of the self-tilt instrument bearing mainly processes the upper surface B and the lower surface A of the part, and ensures that the flatness of the upper surface B and the lower surface A is within 0.02mm, and the parallelism between the upper surface B and the ...
