Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] refer to Figure 2 to Figure 11 , a device for detecting lap size of locking disc grooves of turbine working blades includes a bottom plate 1 and a positioning pin 7 for positioning the exhaust side plane of the tenon of the blade. The bottom plate 1 includes a horizontal part and a vertical part, and the lower surface of the horizontal part of the bottom plate 1 is AB reference Two reference planes, C and D, are on the sides of the two ends of the vertical part of the horizontal part of the bottom plate 1. The three reference planes A, B, C and D are respectively parallel to the A, C and D planes of the edge of the blade lock groove. 1 is fixedly connected with a positioning block 2, a guide plate 4, an alignment block 8 and an alignment pin 9, refer to Figure 8 , the guide plate 4 is provided with a through groove for slidingly mat...

The invention discloses a turbine working blade lock plate groove edge size detection device. The device comprises a bottom plate and a positioning pin. Three sides of the bottom plate are three reference planes of AB, C and D, respectively. The three reference planes are parallel to a side A, a side C and a side D of a blade lock plate groove edge, respectively. The bottom plate is fixedly provided with a positioning block, a calibration block and a calibration pin thereon. The bottom plate is slidably provided with a moving block thereon opposite to the positioning block. A calibration sideC and a calibration side D, which are respectively parallel to the side C and the side D of the blade lock plate groove edge, are arranged on the calibration block. A calibration side A and a calibration side B, which are respectively parallel to the side A and the side B of the blade lock plate groove edge, are arranged on the upper end of the calibration pin. The calibration side A, the calibration side B and the calibration side C are respectively in the same plane with design positions of the side A, the side B, the side C and the side D of the lock plate groove edge when a blade is fixedon the bottom plate. The problems of inconvenient measurement of the four plane sizes of the working blade lock plate groove edge of the turbine and the difficulty in positioning, clamping and detecting at a time.
Description
technical field [0001] The invention belongs to the technical field of detection of turbine working blades of aero-engines, and in particular relates to a detection device for lap size of locking disc grooves of turbine working blades. Background technique [0002] Turbine working blade is one of the key parts of aero-engine parts. It is composed of tenon, edge plate and blade body. There are four plane dimensions that need to be measured on the edge of the lock plate groove. Using a three-dimensional coordinate measuring machine for measurement is inefficient. Such as figure 1 As shown, the dimensions of the side A 10, B 11, C 12, and D 13 of the working blade locking groove of a certain turbine need to be measured. The plane of symmetry 14 forms three angles. Since there is only one three-coordinate measuring machine in the workshop, which is far away from the processing machine tool, it is inconvenient and inefficient to use three-coordinate measurement. The number of ...
