Problems solved by technology

[0002] The blade of the steam turbine includes three parts: the blade root, the blade shape, and the blade top. Among them, the blade root is the part connected to the blade and the rim and has various shapes. The detection of the blade root is an essential and key process. The workshop produces The fungus-shaped leaf roots need to be inspected for their outline size, thickness, and quality. For the inspection of the upper tolerance size of the inner outline size and thickness of the product to be inspected, the commonly used caliper needs to measure multiple points, and different employees have different methods. The size detection error is large, the detection efficiency is low, and it cannot be effectively detected. Therefore, a blade root detection device for steam turbine blades is needed to solve the above problems

Abstract

The invention discloses a blade root detection device of a steam turbine blade, and relates to the technical field of steam turbine blade detection. The blade root detection device comprises a workbench, and a detection device for detecting the contour dimension and thickness of the blade root of a blade is arranged on the workbench and comprises a general detection part which is installed at theleft end of the workbench and is used for the contour and thickness detection and a driving mechanism which is installed at the right end of the workbench and is used for driving a to-be-detected product to move for detection. According to the present invention, the universal detection part and the driving mechanism are arranged to drive the to-be-detected product to move, therefore, one pair of universal detection parts can simultaneously detect whether the inner contour size and the tolerance size of the thickness are qualified or not, errors caused by manually measuring the most data in a sticking point measuring manner according to the techniques and the measurement of different points are reduced, the detection efficiency is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of steam turbine blade detection, in particular to a blade root detection device of a steam turbine blade. Background technique [0002] The blade of the steam turbine includes three parts: the blade root, the blade shape, and the blade top. Among them, the blade root is the part connected to the blade and the rim and has various shapes. The detection of the blade root is an essential and key process. The workshop produces The fungus-shaped leaf roots need to be inspected for their outline size, thickness, and quality. For the inspection of the upper tolerance size of the inner outline size and thickness of the product to be inspected, the commonly used caliper needs to measure multiple points, and different employees have different methods. The size detection error is relatively large, the detection efficiency is low, and effective detection cannot be performed. Therefore, a blade root detection device for ...
