Problems solved by technology

There are many types of blades, and the size and inclination angle of the installation position (tenon) of different types are different. Therefore, when the factory detects the blades, it often needs a spare detection device that corresponds to the blade type one by one, which brings a lot of waste to the factory and brings great harm to the blade detection. many inconveniences

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , a blade profile measurement auxiliary device with adjustable attitude, including a rotating body 2, a moving stop 4 and a fixed stop 5 assembled on the rotating body 2, the moving stop 4 is connected to the fixed stop 5 through a track, and the moving The stopper 4 and the fixed stopper 5 cooperate to fix the tenon of the measured blade. There is a screw 8 next to the movable stopper 4. The screw 8 is fixed on the rotating body 2 through the bracket 13. The tenon of the blade is installed on the movable stopper 4 and the fixed Between the stoppers 5, adjust the screw 8, the movable stopper 4 moves along the linear track, and the gap between it and the fixed stopper 5 changes accordingly, and is used to clamp blades of different sizes. The rotating body 2 is fixed on the adjustable On the base 1, the rotating body 2 carries the blade clampe...

Abstract

The invention discloses a blade profile measuring-aided device with adjustable postures. The blade profile measuring-aided device with adjustable postures comprises a rotary body, a movable baffle block and a fixed baffle block are arranged on the rotary body, the movable baffle block is connected with the fixed baffle block through an orbit, the movable baffle block is matched with the fixed baffle block to fix a tenon of a measured blade, a bolt is arranged at the side of the movable baffle block and fixed on the rotary body through a bracket, the bolt can regulate the movable baffle block to clamp different sizes of blades, the rotary body is fixed on the adjustable pedestal through a press plate, the blade posture can be changed through regulating the rotary body, a standard measuring block is connected with a correction post, the correction post is fixed at one end of the adjustable pedestal, when using a comparison method to measure the blade, the standard measuring block serves as a measuring standard. The blade profile measuring-aided device with adjustable postures regulates the blade posture to meet the blade profile measuring posture requirement according to the size and oblique angle of the blade tenon; the blade profile measuring-aided device with adjustable postures can be used for the snap-gauge, three-dimensional and optical measuring methods for the blade, the workload of the operator is reduced, and the blade profile measuring precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of blade profile size detection, in particular to a blade profile measurement auxiliary device with adjustable attitude. Background technique [0002] Blades are widely used in aviation, nuclear power, ships and other industries related to national economy and people's livelihood. The profile of the blade is generally a complex curved surface, the processing procedure is relatively complicated, and the processing is difficult. The quality of the profile has a decisive impact on the performance of the engine. At the same time, due to the large number, they have been in service for a long time under harsh working conditions, and the performance requirements are extremely high. Therefore, in the detection of engine components, the detection of blade profile is of great significance. [0003] At present, the commonly used blade detection methods include manual card board measurement method, coordinate measurin...
