Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a heating clamp for repairing damaged skin of a rear section of a helicopter rotor. Background Art

[0002] Usually, when a helicopter rotor is damaged, it needs to be removed from the helicopter for repair. This type of repair is usually performed during local flight training. However, if the rotor is damaged during combat or field flight training, it is usually necessary to carry out on-site repairs. Under field conditions, disassembly and repair are basically impossible, so direct on-board repair is required. During the repair process, the damaged part is bonded. The EA9309.3NA glue used for helicopter metal rotor repair has a curing time of about 24 hours at room temperature and takes 3-4 days to cure naturally in a low temperature environment. In addition, the use strength is reduced. Pressurization and heating are necessary process steps. The purpose is to accelerate the curing of the glue while achieving the repair strength, and to ensure the rapid recovery of the rotor's tactical and technical performance. Pressurization can usually be achieved, but heating is relatively difficult. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a heating fixture for repairing the skin damage of the rear section of a helicopter rotor in view of the above shortcomings.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A heating fixture for repairing damaged skin of a rear section of a helicopter rotor comprises a first shell, a second shell, a heating panel, a temperature controller and a fixing part. The first shell and the second shell are rectangular plates. The first shell and the second shell are hinged to one side of the second shell by a rotating shaft. The inner side surfaces of the first shell and the second shell are both inwardly concave arc surfaces, and the heating panels are arranged in the arc surfaces. The first shell and the second shell are used to cooperate and clamp and contact the upper and lower surfaces of the helicopter rotor. The first shell and the second shell are both provided with heating panels, and the outer side of the first shell is provided with a temperature controller. The other ends of the first shell and the second shell are both provided with fixing parts, and the two fixing parts are fixedly connected to the two ends of the first shell and the second shell by fastening bolts.

[0006] Furthermore, the heating temperature range of the temperature controller is 65-75 degrees.

[0007] Furthermore, the first shell and the second shell are both made of high temperature resistant aluminum alloy.

[0008] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0009] The utility model clamps the rotor by arranging the first shell and the second shell, and heats the damaged glue-coated repaired parts on the upper and lower surfaces of the rotor by the heating panel, so that the rotor can be repaired directly on the helicopter, which is more convenient and quick; by arranging the heating panel and the temperature controller, the curing time of the glue can be shortened to within three hours, which is particularly suitable for field repairs in wartime or peacetime, and can quickly restore the tactical and technical performance of the rotor so that the helicopter can be deployed again; the utility model has a small size, a light weight, is easy to carry, and can be used outdoors, indoors and under various climatic conditions.

Therefore, they cannot be understood as limitations on the present invention.

[0019] like Figure 1-4As shown, a heating fixture for repairing damaged skin of the rear section of a helicopter rotor comprises a first shell 1, a second shell 2, a heating panel 3, a temperature controller 4 and a fixing part 5. The first shell 1 and the second shell 2 are rectangular plates. The first shell 1 and the second shell 2 are hinged on one side by a rotating shaft. The inner side surfaces of the first shell 1 and the second shell 2 are both inwardly concave arc surfaces, and the heating panel 3 is arranged in the arc surface. The first shell 1 and the second shell 2 are used to cooperate with each other to clamp and contact the upper and lower surfaces of the helicopter rotor. The first shell 1 and the second shell 2 are both provided with a heating panel 3, and the temperature controller 4 is arranged on the outer side of the first shell 1. The other ends of the first shell 1 and the second shell 2 are both provided with fixing parts 5, and the two fixing parts 5 are fixedly connected at both ends of the first shell 1 and the second shell 2 by fastening bolts.
