Problems solved by technology

[0002] In the process of installing the rudder on the rear beam of the Q400 tail section, due to the long vertical tail plate, it is easy to cause its span to be out of tolerance, resulting in the interference between the installed rudder and the vertical tail plate or the gap is too large, which requires multiple times Rework and repair, causing parts to be scrapped
Cause great economic losses and lead to customer dissatisfaction

Embodiment

[0020] Such as figure 1 As shown, the pendulum-type vertical tail belt plate span positioning and detection device includes a fan-shaped plate 1 and a central shaft 2, and the central angle end of the fan-shaped plate 1 is closely matched with one end of the central shaft 2 to form a fan-shaped plate that swings around the central axis. structure.

[0021] In this embodiment, the central angle corresponding to the fan-shaped plate is 30°. Such as figure 2 As shown, the side of the fan-shaped plate is engraved with a single-side span marking line 4, and the marking line 4 is the maximum value marking line 42 and the minimum value marking line 41 (such as image 3 shown). The distance between the two marking lines of the maximum value and the minimum value is the same as the assembly range satisfied by the vertical tail strap plate.

[0022] The other end of the central shaft is provided with a leading guide rod 3 with a diameter slightly smaller than the central shaft, whi...

Abstract

The invention relates to a tilting vertical tail band plate span locating and detecting device, in particular to the tilting vertical tail band plate span locating and detecting device which is of a tilting type, locates one-side span by taking a central shaft as a standard, and detects assembling results. The locating and detecting device comprises a fan-shaped plate and the central shaft, wherein a central angle end of the fan-shaped plate is closely matched with one end of the central shaft to form a structure of swinging of the fan-shaped plate with the central shaft as the center. The fan-shaped plate swings with the central shaft as the center to detect whether vertical tail band plate span location meets assembling requirements, so the locating and detecting device is simple in structure, easy to operate, accurate to locate and convenient in self-examination, and improves product quality and working efficiency.

Description

technical field [0001] The invention relates to a pendulum-type vertical tail belt plate span positioning and detection device, specifically a pendulum-type design, a single-side span positioning with the central axis as the reference, and a pendulum-type pendulum-type device for detecting the assembly result Vertical tail belt plate span positioning and detection device. Background technique [0002] In the process of installing the rudder on the rear beam of the Q400 tail section, due to the long vertical tail plate, it is easy to cause its span to be out of tolerance, resulting in the interference between the installed rudder and the vertical tail plate or the gap is too large, which requires multiple times Rework and repair, resulting in scrapped parts. Cause great economic losses and lead to customer dissatisfaction. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present inve...
