Screw dismounting tool and using method thereof

Abstract

The invention provides a screw dismounting tool and a using method thereof. The tool comprises a dismounting mechanism, a clamping mechanism and a locking mechanism, wherein the dismounting mechanism comprises a shaft sleeve and a rotary regulation and control assembly, the shaft sleeve is arranged at the position, where a screw is to be dismounted, of equipment, the rotary regulation and control assembly is in threaded connection with the inner wall of the shaft sleeve, the clamping mechanism comprises clamping assemblies arranged on the shaft sleeve and located on the two sides of the shaft sleeve, the locking mechanism is arranged at the end, away from the shaft sleeve, of the clamping assemblies, the using method comprises the following steps that S1, a to-be-disassembled screw is clamped by a clamping piece; S2, the clamping assemblies and the dismounting mechanism are annularly locked on the equipment through the locking mechanism; and S3, a rotating handle and an unscrewing handle are synchronously rotated to eliminate the gap between the clamping assemblies and the equipment, and the screw dismounting operation is completed through the step S4. According to the screw dismounting tool and the using method thereof, the problem that an existing screw dismounting tool needs to unscrew a screw in advance and provide a fulcrum for the tool through an empty threaded hole is solved, the threaded hole cannot be damaged, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of screw removal, in particular to a screw removal tool and a use method thereof. Background technique [0002] The structure of special equipment such as aerial bombs and missiles is generally assembled into a whole structure by a cylindrical rib frame and a curved surface skin through 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. This forced assembly makes the screw bend and deform under 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, due to factors such as environmental corrosion and improper disassembly operations, it will also cause problems such as shallow grooves and scratc...

AI Technical Summary

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
