In aircraft production, the aircraft need go into and go out each station and carry out different work, when going into and go out each station, because guarantee that the aircraft product does not produce the collision with work platform, work platform needs to leave certain safe distance with the aircraft, the aircraft is when the station, personnel need be close to and get into the aircraft and carry out work, above-mentioned safe distance is great in general size, the event must use the expansion plate or turn over the compensation of board, otherwise personnel on the platform, the instrument has the risk, personnel under the platform, the instrument exists and is injured the risk by pounding, personnel can't arrive the work position even when this safe distance is great.

In recent years, the production process of domestic aircraft engines is mature day by day, and more types of aircraft are changed with the domestic engines, so that the problem that the same production line needs to be suitable for both the domestic engines and the foreign engines is solved, but the engines of different types have great difference, and the length, the appearance and the diameter of the engines are greatly different, so that the expansion plate which is originally used for matching with the foreign engines and is used for compensating the gap between the engines and the platform is not suitable for the domestic engines, and workers cannot safely install and debug the engines.

In the production process of an airplane, a clearance compensation device is needed, which can simultaneously compensate the clearances between a working platform and engines of two different models in different shapes.

Disclosure of Invention

In order to meet the development requirement of a domestic engine for airplane reloading, the two-stage double-appearance telescopic compensation device is provided.

A two-stage double-appearance telescopic compensation device comprises a multi-cavity platform, a primary frame, a secondary frame, a primary sliding pair and a secondary sliding pair, wherein a plurality of hollow cavities are arranged on the side surface of the multi-cavity platform close to one side of a product, the hollow cavities are open close to one side of the product, the primary frame is positioned in the hollow cavities, the secondary frame is positioned in the cavity of the primary frame, the primary frame slides in the hollow cavities along the primary sliding pair and is used for compensating a gap between the multi-cavity platform and a first product, when appearance compensation is carried out on the first product, all the secondary frames are retracted into the primary frame, the primary frame extends out to compensate the appearance of the first product, the secondary frame slides in the cavity of the primary frame along the secondary sliding pair and is used for compensating the gap between the multi-cavity platform and a second product, when appearance compensation is carried out on the second product, all the primary frames are retracted into the hollow cavities, extending the secondary frame to compensate for the second product profile.

The one-level frame is divided into two layers along the height, the upper layer is of a cavity structure, one side of the cavity, which is close to a product, is open, the lower layer is of a frame structure, the positions, which are close to the two sides, of the bottom surface of the frame structure of the lower layer are respectively provided with an upwards sunken elongated slot, two one-level sliding pairs are arranged in the elongated slots, and the one-level frame is stacked and arranged on the upwards surface in the hollow cavity of the multi-cavity platform through the two one-level sliding pairs.
