Universal tool capable of quickly disassembling various components

Abstract

The invention discloses a universal tool capable of quickly disassembling various components, and belongs to the technical field of maintenance tools. The universal tool is used for quickly disassembling the various components such as jaws of work rolls, motor connectors and journal gears. The technical scheme includes that a hydraulic pump station and a hydraulic cylinder height adjusting support are fixed onto a movable trolley, a cylinder body of a hydraulic cylinder is mounted on the hydraulic cylinder height adjusting support, a hydraulic pipeline of the hydraulic pump station is connected with the hydraulic cylinder, and a push rod of the hydraulic cylinder is connected with a disassembling device; a connecting ring of the disassembling device is connected with the hydraulic cylinder, connecting rods are connected between the connecting ring and a fixture, and an ejector rod is positioned between the push rod of the hydraulic cylinder and a disassembled component; the fixture is a mandrel or a barrier. The universal tool has the advantages that the universal tool is simple in structure and convenient to use; the maximum designed press-in force F can reach 200T, so that requirements of fields can be completely met, the jaws of the work rolls, the motor connectors, the journal gears, belt pulleys and the like can be quickly disassembled, damage to machines can be prevented, the production cost can be reduced, and the universal tool has an obvious economic benefit and is high in practicality.

Description

technical field [0001] The invention relates to a tool capable of quickly disassembling various parts such as a work roll yoke, a motor handle, and a journal gear of a roll straightening machine, and belongs to the technical field of maintenance tools. Background technique [0002] In the metallurgical industry, work roll yokes, motor adapters, journal gears and pulleys of straightening machines need to be replaced and removed frequently. At present, there are two commonly used dismantling methods. The first one is manual gas cutting and heating dismantling method. In this method, when dismantling the above-mentioned parts, the parts to be dismantled are evenly heated to about 200 degrees Celsius with acetylene, causing the inner holes of the parts to expand and become larger. , and then knock it down with a sledgehammer; the second method is the jack bracket removal method, which is to make a disassembly bracket in advance according to the shape and size of the parts and th...

Problems solved by technology

The first method is not easy to operate, and the safety is not high. Because the acetylene heating temperature and heating range are not easy to control, it is very easy to cause the inner shaft of the component or the installation component to be scrapped and cannot be used. The cost of spare parts will increase greatly, and it is only applicable to the shape of the component. In smaller cases, if the part is too large, it will not be heated

The second method is easy to operate, but it needs to make the disassembly bracket in advance, the production cycle is longer, and the disassembly force is not strong. Once the parts fit too much with the inner shaft, it will be difficult to disassemble. Not the same, each type of disassembly bracket can only be used on one kind of parts, the cost of making all disassembly brackets is too high, it is difficult to select and use, and it is not easy to realize

Since the above two methods cannot meet the needs of production, it is necessary to design a general-purpose tool that can safely and quickly disassemble various parts
