The present invention is achieved in that a kind of hole inwall grinding and polishing fixture, comprise top deflector, top support plate, bottom support plate, baffle at bottom, it is characterized in that: described top deflector and baffle at bottom are set to the circular of thickness, top deflector and baffle at bottom bottom surface are provided with the downward-sloping gradient; Described top support plate and bottom support plate are set to four concentric circles annular grooves outwards progressively amplified successively, first annular groove inwall is provided with some groups of rectangle groove A and rectangle groove B, and rectangle groove A is connected with the second annular groove, the 3rd annular groove, the 4th annular groove from outside to inside in turn; Rectangle groove B is connected with the second annular groove, the 3rd annular groove from outside to inside in turn; Described rectangle groove A, rectangle groove B and the second annular groove, the 3rd annular groove, the 4th annular groove intersection are provided with abrasive material and export.
Preferably, described baffle at bottom is upwards disposed with bottom support plate, thin-walled parts, top support plate, top deflector.
Preferably, the through hole that described abrasive material outlet and thin-walled parts annular are arranged coincides.
Preferably, described rectangle groove A layout alternate with rectangle groove B, the length of rectangle groove A is greater than the length of rectangle groove B.
Preferably, described top deflector and the diameter of baffle at bottom are less than or equal to the diameter of grinding machine cylinder mouth.
Preferably, described top support plate is consistent with the external diameter of top deflector, and bottom support plate is consistent with the external diameter of baffle at bottom.
Preferably, the material that described top deflector, top support plate, bottom support plate, baffle at bottom adopt is AL7075 or steel plate.
Structure of the present invention is simple, reasonable in design, utilizes grinding tool to avoid the distortion produced during thin-walled parts abrasive Flow attrition process, improves operating efficiency while reducing production cost.
