Measuring device for gap of guide blade edge plates

Abstract

A measuring device for the gap of guide blade edge plates belongs to the technical field of aviation motors. The measuring device for the gap of the guide blade edge plates is provided with a transmission mechanism, a force applying mechanism and a positioning mechanism and realizes the effect that the stable and accurate gap measuring data of the guide blade edge plates are obtained under the condition that an external force is applied to the guide blades. The device utilizes multiple uniformly distributed thimbles and a support gasket to realize the effect that the same-level guide blades are subjected to the external force with the uniform size at the same time; the design concept of piling adjusting cushion blocks is adopted, and the aim that one device is suitable for the external force applying function for the multi-level guide blades in the same receiver is realized. The measuring device comprises a chassis, wherein a lifting supporting mechanism, the force applying mechanism and the positioning mechanism are arranged on the chassis; the lifting supporting mechanism is formed by a screw rod, a screw barrel, a guide pin, a dynamometer seat, a sensor for a dynamometer, a press pillar, an angle frame, a guide plate, the thimbles and the support gasket. The force applying mechanism is formed by a first bevel gear, a second bevel gear, a rotary shaft and a support; the positioning mechanism is formed by a base with a through hole, a positioning ring and a hook-shaped press plate.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, in particular to a measuring device for guide vane edge plate gaps. Background technique [0002] The technology of measuring the clearance of the guide vane edge plate under the condition of applying a certain external force to the guide vane has always been a technical bottleneck that is difficult to overcome in production. This content exceeds the functions of traditional measuring devices only for positioning and pressing. Meet the needs. For a long time, the manual traditional method is used to apply force and measure on site, requiring at least three workers to cooperate with the operation at the same time, and the method of measuring symmetrical points one by one is not only low in efficiency, but also has high labor intensity, poor stability, large measurement errors, and serious restrict production. Contents of the invention [0003] Aiming at the problems existing in the prior ...
