Abstract

The invention relates to a casting inner hole processing tool, which comprises a processing head (1), a control wire (2), a processing head protection cover (3), a transmission wire (4), a helical spring protection cover (5) and a motor. The invention realizes the cleaning and mechanical processing of the complex inner wall surface, and also provides a transportation scheme for accurately transporting the machining tools to the complex inner hole or inner wall of the casting; it also provides a supporting structure for the machining tool in the complex inner hole or inner wall of the casting , Improve the quality of casting products and processing production efficiency.

Description

technical field [0001] The invention relates to the field of casting inner hole / inner wall finishing, in particular to a casting inner hole treatment tool and a treatment method, which are especially suitable for the treatment of complex or curved inner holes. Background technique [0002] With the advancement of technology, many types of components in the fields of aviation, aerospace and automobiles are developing towards light weight and high integration, such as complex aluminum alloy casings and casings of aero-engines, aircraft, automobile fuel, and hydraulic system components. Such aluminum alloy parts with highly integrated and complex slender oil circuit, gas circuit, and fuel tank structure are mostly formed by casting method. During the casting process, due to insufficient core strength, core cracking, high filling pressure, and coating Due to uneven reasons, the inner wall of the pipeline / cavity is easy to adhere to stubborn excess objects such as small casting l...
