Description

Technical Field

[0001] The utility model belongs to the field of aircraft parts production and manufacturing, and relates to an elevator tube beam positioning drilling jig clamp. Background Art

[0002] The elevator tube beam assembly is mainly composed of a hollow thin-walled cylindrical tube and two cylindrical forks with a diameter slightly smaller than the tube. The tube beam and the fork are connected by two mutually perpendicular conical bolts, and the fork is respectively connected to the elevator control surface and the rocker arm of the aircraft control system.

[0003] In the past aircraft manufacturing process, when installing the elevator tube beam, it is first necessary to fix the elevator rudder surface and the control system rocker arm in the neutral position through a special clamp, then put the tube and fork together, and install the forks at both ends into the fork ears at the rudder end and the rocker end. After confirming that the rudder scissors difference and step difference meet the technical conditions of the aerodynamic outer edge, mark the position of the tube and fork fixing holes on the tube beam, one person holds the tube, and the other uses a pneumatic drill to drill the initial hole. Because the tube is a thin-walled hollow structure and the space is limited, the hole can only be made from the top of the tube beam downward. At the same time, in order to ensure the drilling position, the tube beam needs to be disassembled, turned 180° and then the above operation is repeated to make the initial hole on the opposite side. Then remove the tube beam, expand and ream the hole on the ground, install the tapered bolts to fix the tube and fork, and finally connect the connected tube beam assembly with the elevator rudder surface and the aircraft control system rocker arm. In the process of hole making, it is easy to exceed the tolerance when marking and positioning the same set of holes after the pipe beam is turned over, and the position accuracy of the two holes processed mainly depends on the skill proficiency of the operator. It is often necessary to perform supplementary processing and correction on the ground, which results in low production efficiency and easily produces defective products. Utility Model Content
