Full-automatic nut disassembly device

Abstract

The invention discloses a full-automatic nut disassembly device. The full-automatic nut disassembly device is characterized by comprising a driving cylinder, a driving cylinder piston, a mounting frame, a mounting base, a mobile tool bit, a nut and a fixed tool bit, and further comprises a driving device, a mounting fixed device and a disassembly device; the driving device is the driving cylinder; the driving cylinder can be a hydraulic cylinder or a pneumatic cylinder; a piston of the driving cylinder is fixedly connected with the mobile tool bit on the mounting base through the mounting frame; the mobile tool bit is movably mounted in the mounting base; the fixed tool bit is fixedly mounted at the other end of the mounting frame; and an operation station for nut disassembly is between the fixed tool bit and the mobile tool bit. The full-automatic nut disassembly device has the advantages of: no use of fire, no use of electricity, no damage of bolt screw threads, convenience, speediness, safety, and efficient solution of the disassembly and replacement difficulties of bolts and nuts.

Description

technical field [0001] The invention relates to the technical field of nut removal tools, in particular to a nut cutter, and in particular to a fully automatic nut removal device. Background technique [0002] Nuts widely used in industrial production are exposed to high temperature or corrosive environments in the open air. Some are rusted to death, and some are damaged due to bumping. In short, it is very difficult to disassemble the nuts if there is a problem. In the past, the nuts and bolts were usually cut off by gas welding. However, in some special working conditions, it is sometimes strictly forbidden to use fire welding operations, such as coal powder bunkers in power plants, high-pressure and high-temperature pipelines in oil pipelines, etc. Replacing nuts and bolts is even more frustrating. Concrete sleeper spike nuts will corrode on the spike bolts due to maintenance and environmental reasons and cannot be removed. If the bolts are damaged by gas welding, other ...

[0002] Nuts widely used in industrial production are exposed to high temperature or corrosive environments, some are rusted to death, and some are damaged due to bumping. In short, it is very difficult to disassemble the nuts if there is a problem.

In the past, the nuts and bolts were usually cut off by gas welding. However, in some special working conditions, it is sometimes strictly forbidden to use fire welding operations, such as coal powder bunkers in power plants, high-pressure and high-temperature pipelines in oil pipelines, etc. Replacing nuts and bolts is even more frustrating

Concrete sleeper spike nuts will corrode on the spike bolts due to maintenance and environmental reasons and cannot be removed. If the bolts are damaged by gas welding, other tools must be used to remove the nuts

The hydraulic nut cutter can easily cut nuts. However, when cutting nuts, the force point of the cutter is often not aligned with the center line of the hydraulic push rod, that is, the piston rod of the hydraulic cylinder. On the line, breaking the nut will generate a large torque, so after a period of use, the hydraulic cylinder will be damaged
