A nut removal tool for metallurgical machinery and equipment

Abstract

The invention discloses a nut dismounting tool for metallurgical machinery and equipment, which comprises a hexagonal bolt installed in a bolt installation hole and a hexagonal nut fixing tube for disassembling the hexagonal bolt, the bottom of the hexagonal nut fixing tube is provided with a hexagonal bolt Hex nuts of the same shape as the clamping ring. In the present invention, when the clamping ring of the hexagonal nut extends into the bolt installation hole, the interference rod will first contact with the top of the hexagonal bolt, and continuously squeeze the interference rod to lift the interference rod. The pushing device drives the clamping block to move, and the clamping ring of the hexagonal nut is in interference fit with the hexagonal bolt. In this way, the side of the hexagonal bolt can be effectively clamped by moving the clamping block, and the corresponding clamping position can be changed by moving the clamping block. Hold the size of the hexagonal bolts, so that it can achieve versatility and avoid frequent replacement of appliances during the disassembly process.

Description

technical field [0001] The invention relates to the technical field of nut disassembly and assembly, in particular to a nut disassembly and assembly tool for metallurgical mechanical equipment. Background technique [0002] At present, in the disassembly process of nuts, especially the disassembly and installation of hexagon nuts, the technical means of the comparison document with application number CN201811151232.1 are usually used. In this way, two bolts are used for clamping and fixing, which is usually time-consuming and labor-intensive, although it can It can adapt to hexagonal bolts and nuts of various sizes and shapes, but there are still several problems as follows: [0003] First of all, in the process of installation and disassembly, it is necessary to continuously adjust the position of the corresponding splint, and this adjustment is usually manually adjusted by the worker, which generally wastes a lot of time and such an adjustment device will take up space, re...

Problems solved by technology

[0002] At present, in the disassembly process of nuts, especially the disassembly and installation of hexagon nuts, the technical means of the comparison document with application number CN201811151232.1 are usually used. In this way, two bolts are used for clamping and fixing, which is usually time-consuming and labor-intensive, although it can It can adapt to hexagonal bolts and nuts of various sizes and shapes, but there are still several problems as follows:

[0003] First of all, in the process of installation and disassembly, it is necessary to continuously adjust the position of the corresponding splint, and this adjustment is usually manually adjusted by the worker, which generally wastes a lot of time and such an adjustment device will take up space, resulting in difficult operation question;

[0004] Secondly, when encountering bolts and nuts that are too tight or need to be too tight, more force is needed to disassemble and install them, and general disassembly and installation tools can only provide one kind of rotational force. The power cannot meet the corresponding matching requirements
