Problems solved by technology

Since the burr is located at the bottom of the hole, especially the intersecting line of the intersecting hole has a complex shape, the burr is not easy to observe and difficult to remove; during use, the burr enters the hydraulic parts or the engine under the action of oil erosion, accelerating Wear and tear of moving parts
Commonly used deburring methods include manual deburring, grinding deburring, die deburring, chemical deburring and ultrasonic deburring, etc. These methods are generally inefficient
Most importantly, due to the narrow space in deep holes and intersecting holes, especially the complex shape of intersecting lines in intersecting holes, existing deburring methods cannot effectively remove burrs

Abstract

The invention discloses a flexible alloy rotary file cleaning tool and method for deep hole and intersecting hole burrs. The cleaning tool comprises a rotary rod and an alloy rotary file. The alloy rotary file is detachably mounted on an end portion of the rotary rod through a seat body. The rotary rod is hollow. The alloy rotary file is movably mounted on an end portion of the seat body through arotating shaft, so that the alloy rotary file can swing at least toward one side with respect to the rotary rod. A coolant passage is machined on the seat body. One end of the coolant passage is communicated with the inner hollow portion of the rotary rod. The other end of the coolant passage extends toward the alloy rotary file and opens toward the side surface of the alloy rotary file. The opening direction of the other end of the coolant passage is substantially perpendicular to the rotating shaft of the alloy rotary file. The design is relatively flexible and can meet the removal of burrsof holes of different sizes within a certain limit.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a flexible alloy rotary file cleaning tool and method for intersecting hole burrs. Background technique [0002] Engines, gearboxes, and hydraulic parts often have deep holes and intersecting holes for the transmission of lubricating oil or hydraulic oil. In order to transmit the oil to the designated position, some of the holes used as oil passages are perpendicular to the workbench, and some are connected to the workbench. at an angle. In deep hole processing, there are often burrs on the hole wall and bottom of the processed hole; in the processing of intersecting holes, serious burrs are often formed at the connection between the two holes. Because the burr is located at the bottom of the hole, especially the intersecting line of the intersecting hole has a complex shape, the burr is not easy to observe and difficult to remove; during use, the burr ...
