Abstract

The invention provides a self-pressurized high-speed abrasive particle flow hole internal surface polishing device. The self-pressurized high-speed abrasive particle flow hole internal surface polishing device comprises two groups of fluid pressurized accelerating mechanisms and clamps which are symmetrically arranged at the left and right ends of a machined workpiece; the fluid pressurized accelerating mechanism comprises a fluid pressurized accelerating cavity, a piston cylinder, a piston, a piston rod and a driving unit; one end of the fluid pressurized accelerating cavity clamps the workpiece by the clamp and is communicated with a workpiece hole, and the other end of the fluid pressurized accelerating cavity is communicated with the piston cylinder; the piston is connected to the interior of the piston cylinder in a matching manner and is connected to the driving unit by the piston rod; and the driving unit can drive the piston to move back and forth in the piston cylinder. The self-pressurized high-speed abrasive particle flow hole internal surface polishing device can solve the problem of difficulty in polishing irregular profiled holes, threaded holes, rifling holes, tiny holes, group tiny holes and the like and has the advantages of high precision, high machining efficiency, small damage and low cost.

Description

technical field [0001] The invention relates to ultra-precision machining, in particular to a self-pressurized high-speed abrasive flow hole inner surface polishing method for polishing the inner surface of special holes (irregular special-shaped holes, threaded holes, rifled holes, fine micro holes, group micro holes, etc.) device. Background technique [0002] With the advancement of modern science and technology, various special holes are more and more widely used in aerospace, aviation, automobile, weapons, electrical appliances, chemical industry, hydraulic pressure, medical and other industries, such as the rifling holes of gun barrels and the threaded holes in precision machine tools , fuel nozzles of internal combustion engines, group microholes on circuit boards, etc., among which the accuracy of the rifling hole of the gun barrel requires that the deformation amount not exceed 1 μm and the inner surface roughness reach more than 0.2 μm, and the number of microholes...
