Abstract

The invention discloses a laser detection apparatus for steam turbine pre-twisted blades. The laser detection apparatus comprises a first slide rail and a second slide rail. A blade detection unit is arranged on the ground between the first slide rail and the second slide rail and comprises a group of blade shaft support seats mounted on the ground. A blade shaft is mounted between the blade shaft support seats and is provided with columns of steam turbine blades to be detected. A first mechanical arm is mounted on the moving guide frame of the first slide rail, and is provided with a laser range finder at the end portion. A PLC control center acquires slit positions of the steam turbine blades in the image data. A second mechanical arm is mounted on the moving guide frame of the second slide rail and is provided with a detection feeler gauge which is used for detecting the slit positions of the steam turbine blades under the control of the PLC control center.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a laser detection device for pre-twisted blades of steam turbines. Background technique [0002] At present, most of the domestic and foreign solutions for steam turbine assembly are manual assembly and inspection. Generally, the blades are assembled, and the gap between the tips of the two blades is detected by a feeler gauge to determine whether the assembly is qualified. This detection method is time-consuming and labor-intensive, and the labor cost is too high. Contents of the invention [0003] The purpose of the present invention is to provide a laser detection device for steam turbine pre-twisted blades to solve the problems in the prior art. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] A laser detection device for steam turbine pre-twisted blades, comprising a first sliding track and a second ...
