Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tools, in particular to a handheld tool for aircraft maintenance. Background Art

[0002] During aircraft cabin maintenance, it is often necessary to dismantle the aircraft's outer shell, such as the engine pylon, radome, and wings. The screws on the aircraft's outer shell are generally very tight.

[0003] After searching, it was found that the application number is CN201911096564.9, and the name is "A multifunctional maintenance tool for disassembling and assembling the shell of aviation equipment." This application addresses the problem that traditional aircraft disassembly and maintenance tools are mostly screw guns. When using screw guns to remove screws, maintenance personnel cannot hold the screw gun, and the handle of the screw gun rotates as a whole, making it impossible for maintenance personnel to hold and control the handle. This is quite troublesome for users. By providing a stop plate, a contact pad, a gripping rod, and a gripping sleeve, when using the device, the user aims the screwdriver at the screw, presses the contact pad against the shoulder, and holds the gripping sleeve on the gripping rod. In this way, the contact area between the aircraft body and the human body is increased. The stop plate and contact pad press against the shoulder, and the aircraft body does not rotate. In this way, the removal of screws from the aircraft shell becomes simple. However, this application still requires the worker to use the shoulder to apply a large amount of pressure, which is still quite laborious. At the same time, the pedal arrangement increases the overall volume and weight, making it more difficult to move. When the screw height is greater than the worker's shoulder, the shoulder cannot exert force, making removal more difficult. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

Figure 1-4As shown, a handheld tool for aircraft maintenance according to an embodiment of the present invention includes a shell 1 and a motor 2. The motor 2 is fixedly installed inside the shell 1, and the output end of the motor 2 is connected to a screwdriver head 5 through a connector 4. This is a common installation structure in the field and will not be described in detail here. A track 6 is fixedly installed on the outer surface of the shell 1, and a slider 7 is slidably connected inside the track 6. Both ends of the track 6 are closed structures to prevent the slider 7 from falling off, and a connecting rod 9 is hinged to the surface of the slider 7 through a first hinge seat 8, and the other end of the connecting rod 9 is hinged to a suction cup 11 through a second hinge seat 10. The top surface of the shell 1 is fixedly connected to a handle 13 through a handle rod 12, which is convenient for staff to hold. When inspecting and disassembling the aircraft shell 1, the screwdriver head 5 can be inserted into the knife groove of the nut of the aircraft shell 1, and then the suction cup 11 is connected to the aircraft shell 1. The surface of the shell 1 is adsorbed and fixed, and the motor 2 can be started to drive the screwdriver head 5 to rotate, and then the screw is removed. During the starting process of the motor 2, the connecting rod 9 and the suction cup 11 resist the torque generated during the rotation, preventing the staff from losing their hands, which greatly facilitates the staff to carry out maintenance and disassembly, and improves the convenience of use. At the same time, this device utilizes the smooth surface of the aircraft shell 1 and adopts the suction cup 11 for fixation. It is easy to install and disassemble, and the fixing stability is high. The staff does not need to tighten it vigorously, and it is more flexible and labor-saving to use. At the same time, the slider 7 can slide up and down along the track 6, and the first hinge seat 8 and the second hinge seat 10 facilitate the connecting rod 9 to rotate up and down, thereby greatly facilitating the staff to move the shell 1 and the screwdriver head 5 up and down, and conveniently move the screwdriver head 5 up to remove the screw when turning the screw, further improving the convenience of use.

[0029] In one embodiment, a battery 3 is fixedly installed inside the housing 1, and the battery 3 is electrically connected to the motor 2 through an electrical connection line.

This is a common control structure and will not be described in detail here.

[0030] In one embodiment, two groups of suction cups 11 are arranged, and the suction cups 11 are symmetrically arranged along the central axis of the housing 1 to improve the stability of the fixation.

[0031] In one embodiment, the slider 7 is a T-shaped structure, and the outer wall of the slider 7 is polished to facilitate sliding up and down.

[0032] In one embodiment, the surface of the housing 1 is densely and evenly provided with ventilation holes on one side of the motor 2 to facilitate heat dissipation of the motor 2.

[0033] Working principle:

[0034] When inspecting and disassembling the aircraft shell 1, the screwdriver head 5 can be inserted into the knife groove of the nut of the aircraft shell 1. Then, the suction cup 11 is adsorbed and fixed to the surface of the aircraft shell 1, and the motor 2 can be started to drive the screwdriver head 5 to rotate, and then the screw is removed. During the starting process of the motor 2, the connecting rod 9 and the suction cup 11 resist the torque generated during rotation, preventing the staff from losing their hands, which greatly facilitates the staff to carry out inspection and disassembly and improves the convenience of use. At the same time, the device utilizes the smooth surface of the aircraft shell 1 and adopts the suction cup 11 for fixing. It is convenient to install and disassemble, and has high fixing stability. The staff does not need to tighten it vigorously, which is more flexible and labor-saving to use. At the same time, the slider 7 can slide up and down along the track 6, and the first hinge seat 8 and the second hinge seat 10 facilitate the connecting rod 9 to rotate up and down, thereby greatly facilitating the staff to move the shell 1 and the screwdriver head 5 up and down, and conveniently move the screwdriver head 5 up to remove the screw when turning the screw, further improving the convenience of use.
