Inner-hole finishing machine for rockshaft

Abstract

The invention discloses an inner-hole finishing machine for a rockshaft. A hydraulic drive stepping rockshaft material conveying device is arranged on a stander; a sand blasting bin and an anti-rust liquid spraying bin are arranged in the material conveying device; the sand blasting bin is provided with a hydraulic material feeding door and a hydraulic material discharging door; a hydraulic stretchable sand blasting gun extending into the sand blasting bin is arranged on the side wall of the sand blasting bin; a lever type hydraulic material pressing device extending into the sand blasting bin is arranged beside the sand blasting gun; a hydraulic stretchable air blowing gun extending into the sand blasting bin is arranged on one side of the sand blasting gun of a sand blasting bin shell; a lever type hydraulic material pressing device is arranged beside the hydraulic stretchable air blowing gun; an anti-rust liquid coating device is provided with a hydraulic stretchable liquid spraying gun extending into the liquid spraying bin; and a lever type hydraulic material pressing device is arranged beside the liquid spraying gun. According to the invention, burrs at an inner aperture are removed from a radial oil hole of a rocker arm blank through a sand blasting method; the burrs at the inner aperture are well and comprehensively removed from the radial oil hole of the rocker arm blank; the surface of the inner wall of a rocker arm shaft pipe can be impacted and ground, so that impurities, burrs and oxidized skins on the inner surface of the rocker arm shaft pipe can be cleared away; and therefore, the inner full surface of the rocker arm shaft pipe is smooth, clean and anti-rust, and the surface strength is improved.

Description

technical field [0001] The invention relates to a sandblasting cleaning machine tool for sandblasting the surface of a metal workpiece, in particular to a sandblasting cleaning machine tool for sandblasting the inner wall of a metal short pipe. Background technique [0002] The sandblasting machine tool is a device that uses the high-speed abrasive continuously ejected by the sandblasting machine to clean or strengthen the surface of the metal workpiece. [0003] The sandblasting machine tool has a frame with a workpiece conveying device on the frame. There is a sandblasting chamber in the middle of the workpiece conveying device. The sandblasting chamber has a vertical shell. The right side of the sandblasting chamber shell has a feeding door. There is a discharge door on the left side of the bin shell, a sandblasting gun extending into the bin on one side of the sandblasting bin, and an abrasive outlet at the lower end of the blasting bin. When in use, connect the sandbla...

AI Technical Summary

Problems solved by technology

Since the cylindrical surface in the blank tube of the rocker arm shaft has a certain shape and position deviation, and the position of the burr in the radial oil hole is not very regular, the method of scraping off the rocker shaft with a rotary drill cannot be well and comprehensively removed. The burrs in the radial oil hole of the arm shaft blank may generate new burrs when the drill is scraped off. It is also labor-intensive and time-consuming to remove the burrs in the rocker shaft tube with this method, and the processing efficiency is low
