Abstract

The invention belongs to a cutting machine for cutting circles on arc faces and particularly relates to a portable saddle-shaped cutting machine. The portable saddle-shaped cutting machine comprises a fixed base, a great circle cutting mechanism and a small circle cutting mechanism; the great circle mechanism comprises a great circle cutting spindle arranged on the upper portion of the fixed base, and a lifting sliding table is arranged on the great circle cutting spindle and connected with a lifting arm; the small circle cutting mechanism is arranged at the end, away from the lifting sliding table, of the lifting arm and comprises a telescoping mechanism connected with the lifting arm, and a cutting mouth assembly is arranged at the bottom of a rotary air distribution assembly which is arranged at the end, away from the lifting arm, of the telescoping mechanism. The portable saddle-shaped cutting machine is a perforating machine widely applicable to national defense industry, shipbuilding and ocean engineering, pressure vessels for chemical industry, nuclear power plant equipment and utility boiler industry, and is capable of not only perforating on cylindrical shells and oval shells but also cutting projection round holes on other types of complex spatial curved surfaces and cutting variable-angle double grooves.

Description

technical field [0001] The invention belongs to the field of metal cutting, and more specifically relates to a cutting machine for cutting circles on an arc surface, which is called a saddle cutting machine. Background technique [0002] In mechanical processing, it is often necessary to cut a circle on an arc-shaped metal surface, which is usually called a saddle-shaped cutting. During the cutting process, the positioning and cutting diameter are not easy to determine and position, and it is easy to deviate during the cutting process, making The cutting circle is deformed or fails to meet the technical requirements, seriously affecting the quality and performance of related equipment. Under this background technology, this technical scheme proposes a saddle-shaped cutting machine, which is widely used in the drilling machine in the defense industry, shipbuilding and ocean engineering, chemical pressure vessels, nuclear power equipment, and power plant boiler industries. Th...
