Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aviation detection, especially a slide rail seat installation simulation device. BACKGROUND

[0002] At present, engineering design has strict tolerance requirements for the slide rail hole of the passenger cabin floor in the butt joint area of the fuselage section, but in the actual butt joint work, the step difference gap value of the pose measurement point and the end face of the fuselage section is usually given priority to guarantee, resulting in that the slide rail hole is prone to exceed the tolerance, and further resulting in that the seat cannot be installed on the slide rail according to the engineering drawing requirements.

[0003] To solve the above technical problems, the following two solutions are usually used in the prior art: 1) measuring the position of the slide rail hole by a laser tracker, and verifying whether the seat can be installed on the slide rail according to the measurement data; 2) directly verifying using a positioning pin gauge. Among them, the laser tracker needs to be operated by at least two workers, one responsible for controlling the laser tracker, and the other responsible for placing the target ball one by one on the existing landmark points in the factory building to establish the full machine coordinate system, which results in that the laser tracker is relatively cumbersome to set up each time, and the measurement time is relatively long. Moreover, since the slide rail hole is located inside the fuselage barrel section, the measurement path interferes with the fuselage structure more, resulting in that it is difficult to select the laser tracker setting position. At the same time, in the process of manually placing the target ball, the operator needs to go in and out and walk in the fuselage, which is easy to disturb the aircraft itself, and further affect the accuracy of the measurement data. The positioning pin gauge can only reflect whether the seat can be installed on the slide rail, and cannot provide greater reference significance for the accumulation and analysis of detailed data and subsequent tolerance distribution research.

[0004] Therefore, there is an urgent need for a slide rail seat installation simulation device with simple structure and convenient operation, which can also provide data support for subsequent tolerance distribution research to solve the problems existing in the prior art. UTILITY MODEL CONTENT

[0050] Both ends of the second mounting plate 121 extend out of the second connecting block 122 in the front-rear direction, wherein the end of the second mounting plate 121 extending out of the front of the second connecting block 122 is provided with a second sliding groove 1211, and a second sliding block 1212 is slidingly arranged in the second sliding groove 1211, and one simulation piece 2 is arranged on the second sliding block 1212, and the end of the second mounting plate 121 extending out of the rear of the second connecting block 122 is fixedly provided with three simulation pieces 2, and when the second sliding block 1212 is moved, the second sliding block 1212 drives the simulation piece 2 on the front side to move towards the simulation piece 2 on the rear side in the direction of approaching or moving away, thereby being able to adjust the distance between the simulation pieces 2 at both ends of the second mounting plate 121.

[0051] It should be noted that the number of simulation pieces 2 installed at the front and rear ends of the first mounting plate 111 and the second mounting plate 121 can be adaptively adjusted according to the foundation structure to be simulated, and is not limited herein.

In the embodiment, the number of the first placement hole 71, the calibration hole 72 and the second placement hole 73 on the left and right sides of the calibration piece 7 is three in front and three in back, and they are arranged in one column respectively, so that they can correspond to the simulation pieces 2 on the first connecting piece 11 and the second connecting piece 12 one by one. In the installation simulation process, the lower limit size simulation piece 21 or the upper limit size simulation piece 22 is first installed on the installation rack 1, and then the lower limit size simulation piece 21 or the upper limit size simulation piece 22 is placed in the calibration hole 72 for calibration.
