Description
Technical Field
The utility model relates to the technical field of machining of long pull rod joints of a helicopter control system, in particular to a machining tool for a single lug surface of a joint at two ends of a long pull rod.
Background
The connecting column of the AC311A type machine inhaul cable component is fixed with the steel wire rope in a brazing mode, and after welding and fixing, strength test is carried out according to 50% pull-out force (250N), so that the strength of a welding line is verified. Because the external dimension of the connecting column is too small (the external dimension is phi 5.2mm and the length is 7.8 mm), the conventional pull-out test equipment of the company cannot carry out effective clamping, so that the pull-out test of the part cannot be carried out.
Disclosure of Invention
The purpose of the utility model is as follows: an auxiliary tool for a pull-out test of a steel cable assembly is designed, so that effective clamping between the steel cable assembly and equipment after welding is completed is ensured, and the pull-out test is carried out.
The technical scheme is as follows:
an auxiliary tool for a pull-out test of a steel cable assembly is provided, and comprises a pull ring 1, a connecting pipe 3 and a nut 2; the outer wall of the connecting pipe 3 forms external threads which are matched with the threads of the nut; the inner wall of the connecting pipe 3 is provided with a protruding limiting part, the protruding limiting part is used for limiting the end of the steel cable, and the steel cable body can penetrate out from one end of the connecting pipe; the outer wall of the connecting pipe is provided with a T-shaped opening, and the end part of the steel cable can be positioned into the connecting pipe through the opening; the other end of the connecting pipe is connected with the pull ring; rotating the nut can close the opening.
Further, the pull ring is a flexible tether. The flexible tether is a steel wire rope with the diameter of 2.5 mm.
Further, the nut is an M12 nut.
Further, the nut is capable of closing at least a maximum opening area of the T-shaped opening.
Further, a through hole perpendicular to the axial direction of the connecting pipe is formed in the other end of the connecting pipe, and the pull ring penetrates through the through hole.
The ends of the steel rope form a welding connection column, and the welding connection column has a larger diameter relative to the steel rope body. The nut can prevent the deformation of the tubular connecting rod after repeated stress and uneven stress caused by falling of the steel wire rope when the tubular connecting rod is stressed.
The utility model has the beneficial effects that: the utility model has simple and practical structure, can realize quick installation, improves test efficiency, ensures strength, improves safety, does not interfere a test piece, and has accurate test data.
