Nut unscrewing device and application method thereof

Abstract

The invention provides a nut unscrewing device and an application method thereof. The nut unscrewing device comprises a body with a working hole, and further comprises a rotatable impact beam. Both ends of the body are provided with first bending portions; a main shaft is fixed to the body; the rotatable impact beam sleeves the main shaft; and two ends of the rotatable impact beam impact the first bending portions when the rotatable impact beam rotates around the main shaft. As impulse of the rotatable impact beam is transmitted to the first bending portions, the first bending portions at two ends of the body are impacted simultaneously by the rotatable impact beam so as to drive the body to drive a nut to rotate together; thus a large torque is applied to the nut. The nut unscrewing device has the advantage of saving force for screwing or unscrewing big nuts, and is easy to operate, convenient and reliable, is small in size with low requirement for operation space, and is convenient to carry and store.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a device for disassembling large nuts and a method for fastening or disassembling large nuts using the disassembling device. Background technique [0002] Most of the equipment that needs to be fixed is fixed with bolts and hexagonal nuts. When the required tightening torque is large, large nuts are used. The loading and unloading of large nuts requires a large torque, especially for disassembling large nuts that have been fixed for a long time and have some corrosion. , The disassembly tool should be easy to carry; and the disassembly and assembly of the inner cylinder of the washing machine is fastened to the large nut. Because the large nut is at the bottom of the inner cylinder, the disassembly tool can be used in a small operating space. [0003] At present, the loading and unloading of large nuts is generally carried out by using the extended handle of...

Problems solved by technology

[0003] At present, the loading and unloading of large nuts is generally carried out by using the extended handle of the sleeve. The sleeve is placed on the large nut, and the long handle is used to rotate to provide a large torque; however, the disassembly tool of the extended handle of the sleeve is not only large in size, The length is also relatively long, it is not easy to operate and carry, and requires a large operating space; and it still relies on the strength of the arm to be applied to the extended handle when using it. When the required torque is large, it is still very time-consuming and laborious, such as disassembling for long-term use. Corroded large nut
