Abstract

The invention discloses a turning section type workpiece back-off inner diameter checking fixture, and belongs to the technical field of inner diameter detection equipment. In the invention, a problemthat an existing conventional checking fixture cannot accurately measure an inner diameter of a back-off structure is solved. The fixture comprises a base, an inspection assembly and a leveling assembly, wherein the inspection assembly and the leveling assembly are positioned above the base. A workpiece is leveled and fixed on the base through the leveling assembly, the inspection assembly comprises a telescopic inspection disc, a sliding block and a sliding rail, the telescopic inspection disc is arranged on the base in a sliding mode through the sliding block and the sliding rail, and back-off inner diameter detection is performed on the workpiece through the telescopic inspection disc. The leveling assembly is used for leveling the workpiece before inspection, and movement of the telescopic inspection disc in a certain area is achieved through cooperation of the sliding block and the sliding rail. The telescopic inspection disc has a variable-diameter function so as to ensure thatthe telescopic inspection disc smoothly enters a back-off area for measurement. In the invention, accurate measurement of the inner diameter of a back-off position of the turning section type workpiece can be realized so that product quality is ensured and production efficiency is improved.

Description

technical field [0001] The invention relates to an undercut inner diameter inspection tool for workpieces such as turning sections, and belongs to the technical field of inner diameter inspection equipment. Background technique [0002] The turning section workpiece is an important structural part of the aircraft engine. It is the inlet and passage of the air required for the aircraft engine to work. The aircraft engine is a ramjet engine. The compressor and combustion chamber work normally, and the turning section plays an important role in improving the flight performance of the aircraft. There is an undercut structure in the turning section, and the inner diameter at the position of the undercut structure is very important during assembly, which will directly determine the assembly effect of the turning section and the inlet section, and then determine the flow rate and stability of the gas required for the aircraft engine to work . Traditional conventional inspection t...
