TECHNICAL FIELD
[0001] The utility model relates to the field of equipment for automobile parts machining, especially a manual deburring rod for the intersection surface of the inner side of a turbine shell. BACKGROUND
[0002] Turbine is a fan in the engine of an automobile or an airplane, which blows fuel vapor into the engine by using exhaust gas to improve the performance of the engine. Turbine is a rotary power machine that converts the energy of flowing working medium into mechanical work, and it is one of the main components of an aero-engine, a gas turbine and a steam turbine. The outer surface of the turbine is often provided with a shell to protect the turbine body.
[0003] At present, after the turbine shell is processed, there are often some burrs on the inner side of the turbine shell. Some of these burrs need to be removed manually. However, the manual deburring rod wears out quickly during use, and it puts a lot of burden on the hands of the workers during use. Therefore, the applicant improved the existing manual deburring rod in 2020. The improved manual deburring rod has been fully applied, but some new problems have been found in the use of the past two years. Specifically, since the structure of each turbine shell is not the same, it is often customized, so it is difficult for the fixed first supporting rod to meet the needs of the existing operators, because it is not convenient to send it in a straight line in some places, so the structure needs to be improved.
