Abstract
The utility model discloses a device for disassembling a fastener by utilizing an electric heating mode, which comprises an electric heating module, a fastener outer part, a fastener inner part, a mobile power supply and a mobile power supply switch.
Description
Technical Field
The utility model belongs to the technical field of mechanical manufacturing and mechanical assembly, and directly relates to disassembly between interference assembly of fasteners, in particular to a device for disassembling fasteners by utilizing an electric heating mode.
Background
When the outer fastener piece and the inner fastener piece work normally, the outer fastener piece and the inner fastener piece move at the same speed, and interference fit is adopted between the outer fastener piece and the inner fastener piece, so that the outer fastener piece and the inner fastener piece are tightly matched, and the fact that relative movement is not generated is ensured. Because the interference fit between the fasteners is relatively large, particularly long-time movement is performed, and external environment influence is added, deformation is generated between the fasteners, and the disassembly is difficult. In actual production, the fasteners are detached and heated by using a cutting gun flame or by using an oil bath, the flame is heated unevenly, equipment is easy to damage, the oil bath heating has severe requirements on the shape of the fasteners, and a device for detaching the fasteners by using an electric heating mode is very necessary to be studied.
Disclosure of Invention
The purpose of the utility model is that: the device for disassembling the fasteners by utilizing the electric heating mode can conveniently and quickly disassemble the connection between the fasteners.
The utility model relates to a device for disassembling a fastener by utilizing electric heating, which mainly comprises an electric heating module, a fastener outer part, a fastener inner part, a mobile power supply and a mobile power supply switch.
Preferably, the permanent magnet is embedded on the electric heating module, so that the electric heating module is conveniently and tightly connected with the outer piece of the fastening piece in the heating process, and heat energy is conducted to the outer piece of the fastening piece from the electric heating module to the greatest extent, so that the temperature of the outer piece of the fastening piece is close to that of the electric heating module.
Preferably, the size and the number of the electric heating modules can be designed according to the size of the fastener, so that the energy conducted to the outer fastener piece is ensured to be uniform, the outer fastener piece can be expanded uniformly due to heating, the interference force between the outer fastener piece and the inner fastener piece is reduced, and the outer fastener piece and the inner fastener piece can be conveniently detached.
The beneficial effects of the utility model are as follows: the electric heating module is tightly attached to one side of the outer piece of the fastener or the outer ring of the outer piece of the fastener, the temperature is increased through the electric heating module, heat energy is conducted to the outer piece of the fastener, and the expansion coefficient of the outer piece of the fastener is far greater than that of the inner piece of the fastener, so that the interference force between the fasteners is reduced, and the purpose of conveniently disassembling the fasteners is achieved. The device is not uniformly heated and is easy to damage compared with the flame heating adopted at present; compared with the condition that the oil bath heating has severe requirements on the shape of the fastening pieces, the device has simple structure, is easy to operate, is not influenced by environment and places, meets the overhaul requirement of quick disassembly, and solves the difficult problem of difficult disassembly among the fastening pieces in the overhaul process of equipment.
