Problems solved by technology

[0011] To sum up, there is an urgent need for a screw removal tool and its use method to solve two problems in the prior art screw removal tools: 1) it is easy to damage the threaded holes on the equipment; The threaded hole provides a fulcrum for the tool, which not only increases the maintenance workload, but also destroys the surface structural strength of the equipment

Embodiment 1

[0054] see Figure 1-3 , a screw disassembly tool, including a disassembly mechanism, a clamping mechanism and a locking mechanism, the disassembly mechanism includes a shaft sleeve 1 and a rotation control assembly, and the shaft sleeve 1 is provided in the device (specifically, a thin-walled cylindrical shell 01 ) on the position of the screw to be disassembled, the rotation control assembly is threadedly connected with the inner wall of the shaft sleeve 1, and is used for adjusting and loosening the screw to be disassembled on the device to complete the disassembly operation;

[0055] The clamping mechanism includes clamping assemblies (ie, two sets of clamping assemblies) respectively disposed on the shaft sleeve 1 and located on both sides of the shaft sleeve 1, for clamping equipment;

[0056] The locking mechanism is provided on the end of the clamping assembly away from the shaft sleeve 1, and is used for circumferentially locking the clamping assembly and the dismount...

Abstract

The invention provides a screw removal tool and a method of using the same. The tool includes a removal mechanism, a clamping mechanism and a locking mechanism. The removal mechanism includes a shaft sleeve and a rotation control assembly. The shaft sleeve is arranged on a device to be The screw position is disassembled, and the rotation control assembly is threadedly connected with the inner wall of the shaft sleeve; the clamping mechanism includes clamping assemblies arranged on the shaft sleeve and located on both sides of the shaft sleeve; the locking mechanism is arranged at a distance from the clamping assembly. on one end of the shaft sleeve. The use method includes step S1 that the clamping member clamps the screw to be disassembled; step S2 locking mechanism circumferentially locks the clamping assembly and the disassembly mechanism on the equipment; step S3 synchronously rotates the rotating handle and loosens the handle to eliminate the clamping assembly Clearance between the device and the device; complete the screw removal operation through step S4. The invention solves the problem that the existing screw removal tool needs to unscrew the screw in advance and use the vacated threaded hole to provide a fulcrum for the tool, the threaded hole is not damaged, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of screw removal, in particular to a screw removal tool and a method of using the same. Background technique [0002] The structure of special equipment such as aviation bombs and missiles is generally composed of cylindrical rib frames and curved skins assembled into an overall structure by a large number of screws. However, because the nail holes on the curved skin are difficult to match with the threaded holes on the rib frame, the forced assembly method is often used to screw the screws into the nail holes and threaded holes to complete the installation work. The forced assembly makes the screw bend and deform under the action of the radial shear force between the curved skin and the rib frame for a long time, making it difficult to disassemble the screw smoothly. In addition, affected by factors such as environmental corrosion and improper disassembly operations, it will also cause problems such as sha...
