Problems solved by technology

If the structure of the detection device is unreasonable or the upper lock detection and assembly methods are unreasonable, not only the efficiency is low, but also the quality is not easy to guarantee, and even important parts will be scrapped.
[0004] The traditional uplock detection tool can only detect the left part of the uplock, and the detection of the right part has a set of tooling that is completely symmetrical to it. It is impossible to simulate the locking and unlocking status of the aircraft landing gear and perform gap detection and Dimensional guarantee, cannot be used as a test device, it needs to go back and forth between the test and assembly process many times, the detection efficiency is low, and the detection effect is difficult to guarantee

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0035] An uplock gap detection device includes a supporting part, a pressing part, a positioning part, assembly accessories and test accessories.

[0036] Supporting parts: the left vertical board 1 and the right vertical board 7, the upper flat board 6 and the lower flat board 11, which are connected by 12 screws 12 and 8 pins 13. Wherein the left and right vertical plates are fully symmetrical and have a waist-shaped groove to facilitate the up and dow...

Abstract

The invention discloses an upper lock gap detection device and a detection assembly method. The upper lock gap detection device comprises a support framework and a clamp body arranged on a work bench and used for fixing an upper lock. The bottom end of the support framework has a positioning surface positioned on the work bench; the top end of the support framework is provided with a fork shape member capable of moving up and down with respect to the support framework; the fork shape member is used for carrying out press adjustment on a lock hook of the upper lock; and the support framework is provided with a plurality of plug pins arranged transversely for press positioning of the upper lock after being assembled. The gap detection device can be used for a plurality of gap detection and dimension guarantee of the upper lock; and through reasonable process arrangement, the quality of the product is ensured, and meanwhile, higher production efficiency is also ensured.

Description

technical field [0001] The invention relates to an upper lock gap detection device and a detection and assembly method, which belong to the field of aviation equipment. Background technique [0002] The aircraft uplock is used for the main landing gear of an aircraft. When the main landing gear is retracted, the uplock is in the locked state, and the main landing gear is fixed at the stowed position. Before the main landing gear is put down, the uplock is unlocked to realize the locking of the landing gear. Smooth down is an important part of the landing gear system. [0003] There are many parts in the upper lock, the structure is relatively complex, the airtight performance is high and the pressure is high, and there are many gaps and dimensions that require inspection and guarantee. The upper lock includes two specifications, left and right. Uplock is made of lock housing, piston rod, shackle, lock key, spring, push rod, rocking arm, dial ring, nozzle and other parts. ...
