Abstract

The invention discloses a vortex type hole surface rolling-polishing finishing processing device and method and belongs to the technical field of mechanical part surface finishing processing. The vortex type hole surface rolling-polishing finishing processing device is characterized in that the action force between a spherical material to be polished and a hole surface is adjusted by controlling the rotating speed of a motor externally, and therefore constant-pressure processing is achieved, economical efficiency of processing uniformity is guaranteed, operation is easy, processing parameters are controlled in real time, and flexibility, automation and controllability of processing are achieved. The device solves the problems that an ordinary hole surface finishing processing device is not easy to move and hole surface processing of large parts and parts which are hard to position and clamp is difficult; the device is good in economical efficiency and easy to operate. The device is simple in structure, low in cost and convenient to control, and hole surfaces within a certain size range can be processed through finishing heads in the same size.

Description

technical field [0001] The invention discloses a vortex-type hole surface rolling and finishing device and a processing method thereof, which belong to the technical field of mechanical parts surface finishing, and specifically relate to a method of adjusting the force between a spherical abrasive and a hole surface by externally controlling the speed of a motor, so as to realize Constant pressure processing, economical and simple operation to ensure uniform processing, real-time control of processing parameters, to achieve flexible, automatic and controllable processing device for hole surface finishing.
