Run-through double-sided chamfering machine

The invention discloses a run-through double-sided chamfering machine, comprising a pedestal, wherein a supporting top bowl, a rotary cutter disk, a mainframe box and a slip are coaxially mounted on the pedestal sequentially; the rotary cutter disk is connected to an output shaft of the mainframe box; the rotary cutter disk and the mainframe box are provided with central round holes which run through mutually; a front knife rest and a rear knife rest which are opposite to each other are arranged on the rotary cutter disk; a front cutting knife is mounted on the front knife rest; the front cutting knife is provided with an axial feeding mechanism and corresponds to the front end chamber position of a connecting hoop with an oil pipe; a rear cutting knife is mounted on the rear knife rest; the rear cutting knife is provided with a radial feeding mechanism and corresponds to the rear end chamber position of the connecting hoop with the oil pipe; the supporting top bowl is driven by a hydraulic cylinder; the hydraulic cylinder is mounted on a bracket; the bracket is fixed on the pedestal; and a front end limiting part of the connecting hoop with the oil pipe is fixed on the pedestal. The run-through double-sided chamfering machine has high processing efficiency and low risk.
