Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] The three-dimensional schematic diagram of the measuring tool structure of the present invention is as follows: figure 2 As shown, it is mainly composed of base 1, pressure rod 4, nut 3, bolt, vertical plate 7, support block 8, hinged seat 9, base 10, angle indicating block 5 and rotating ring body 6, and the vertical plate 7 is perpendicular to the base. On the upper end face of 1, the vertical plate 7 is provided with a through hole, the front end of the vertical plate 7 is the base 10, the rear end through hole has a ring of annular protrusions on the outer circumference, the rotating ring body 6 is sleeved on the annular protrusion, and the rotating ring There is a radial through groove on the body 6, and a through hole on the annular protrusion. The angle indicating block 5 is slidably connected in the through groove and the throug...

Abstract

The invention discloses a measuring tool and method for measuring the angle of a rectifying blade with a positioning pin. The measuring tool mainly consists of a base, a pressing rod, a nut, a bolt, a vertical plate, a supporting block, a hinged seat, a base, an angle indicating block and a rotating Composed of a ring body, the vertical plate is perpendicular to the upper end surface of the base, and a through hole is opened on the vertical plate. There is a radial through groove on the rotating ring body, and a through hole on the annular protrusion. The angle indicating block is slidably connected in the through groove and the through hole, and connects with the protrusion on the rectifying blade positioning block through the gap at the end. The platform is inserted to form an extended structure of the datum surface on the boss. The support block is located on the upper end surface of the base. The contour of the upper surface of the support block is consistent with the curve shape of the section to be measured on the blade. One end of the pressure rod is hinged on the hinged seat. The other end is inserted into the bolt through the notch and locked by the nut. The invention can conveniently judge whether the dimension of rectifying blade parts is qualified after processing.

Description

technical field [0001] The invention belongs to the technical field of aero-engine manufacturing, and relates to a processing method for a rectifying blade with a positioning pin, in particular to a measuring tool and a measuring method for measuring the angle of a general rectifying blade part. Background technique [0002] In an aero-engine, the fairing blade is a key component in the compressor. The rectifying blade with locating pin is a typical part of the compressor rectifying blade. like figure 1 , Picture 1-1 and Figure 1-2 As shown in the figure, the rectifying blade with positioning pin is mainly composed of a second-stage rectifying blade, a bushing and a positioning block of the high-pressure compressor. The second-stage rectifying blade, the bushing and the positioning block are on the same axis, and the boss On the positioning block, there is a reference plane M on the boss of the positioning block, and the positioning pin is inserted on the positioning b...
