Abstract

The invention discloses a flexible cable inertia hammer. The hammer comprises a primary hammer head and a secondary hammer head which are connected together, one end of a flexible cable sequentially penetrates through the primary hammer head and the secondary hammer head and is sequentially connected with a collision head, a lock head and a ball head, and a traction cable is arranged at the other end of the flexible cable. According to the principle of the inertia hammer and the characteristics that the flexible cable is small in size and can bypass the space to block obstacles, the problem that parts are difficult to dismantle in the narrow space is solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools and relates to a flexible cable inertia hammer. Background technique [0002] The disassembly of mechanical equipment often requires the help of a large number of tools due to the difficulty of the operation. In order to ensure a compact structure, the mechanical parts are installed closely with each other, and interference fit is often used, which makes disassembly very difficult, and disassembly and assembly work is even more difficult when the space is narrow. For example, when disassembling disc parts such as gears and flanges installed in the center of the long axis, on the one hand, the strength of the human arm is limited, and on the other hand, it is difficult to clamp the parts to be removed, making the disassembly work difficult. Destructive disassembly is often used as a last resort, causing unnecessary waste and delaying the scheduled operation of the equipment. Contents of...
