Abstract

The invention provides a device for removing burrs in workpiece oil channel holes. The device comprises a liquid inlet end and a liquid outlet end. The liquid inlet end comprises a hydraulic pump, a check valve and a liquid inlet pipe. One end of the liquid inlet pipe communicates with the check valve. The other end of the liquid inlet pipe communicates with at least one oil channel hole of a workpiece. The liquid outlet end comprises a liquid outlet pipe, a reversing valve and a back pressure valve. One end of the liquid outlet pipe communicates with at least one oil channel hole of the workpiece. The other end of the liquid outlet pipe communicates with the reversing valve. The other end of the reversing valve communicates with the back pressure valve. The invention further provides a corresponding method for removing the burrs. Through two times of hydraulic shocks, liquid forms hydraulic vibration shock waves in the oil channel holes, thus the insides of the oil channel holes are washed repeatedly at high pressure, the burrs in the oil channel holes are removed completely, and the conditions that in the workpiece use process, burrs fall off to damage other devices and the wholeequipment are avoided effectively.

Description

technical field

[0001] The invention relates to a device and a method for removing burrs in oil passage holes of workpieces. Background technique

[0002] At present, in the technical field of removing and cleaning the burrs in the oil passage hole of the workpiece, brushes with different hardness are mainly used to move back and forth to remove them, and then perform high-pressure flushing by hydraulic pressure. Because some workpieces, such as automobile engine block and cylinder head, have small diameter and long length of oil passage holes, the burrs in the oil passage holes, especially the burrs at the intersection of two oil passage holes, are difficult to remove with a brush, Generally, it is difficult for high-pressure liquid to completely wash the burrs in the oil passage hole. These burrs have not been completely removed. Once they fall off due to vibration, collision or pressure shock during engine use and then run with the oil, serious quality problems such as s...
