Induction heating hydraulic disassembly and assembly machine

Abstract

The invention relates to an induction heating hydraulic disassembly and assembly machine. The machine includes a hydraulic top pulling device, a control device and a lifting adjustment device. The lifting adjustment device includes a frame and an adjusting screw rod, and the hydraulic top pulling device is connected with the frame by the adjusting screw rod; The hydraulic top pulling device comprises a hydraulic jack, a pull rod, a draw hook and an inner housing, the draw hook is connected with the pull rod through a positioning sleeve, and the pull rod is connected with the inner housing through a pull rod support sleeve; The inner housing is formed in a cylindrical structure, and electromagnetic coils are disposed on an outer circumference of the inner housing; and the electromagnetic coils are connected to the control device through lead wires, and outer surfaces of the electromagnetic coils are provided with shells. The induction heating hydraulic disassembly and assembly machine is formed by adopting combination of electric induction heating and a hydraulic jacking system, the height can be arbitrarily adjusted, and the machine is suitable for a wheel train which is difficultto disassemble due to an interference fit. The induction heating hydraulic disassembly and assembly machine can be widely used for heating and disassembling of various annular hole-shaped metals suchas bearings, main wheels, bushings, shaft sleeves, diameter rings, pulleys, contraction rings and couplings, and the purpose of interference disassembly and assembly is achieved through heating expansion.

Description

technical field [0001] The invention relates to the technical field of assembly tools for mechanical equipment, in particular to a special disassembly and assembly tool for parts of mechanical equipment hole shaft interference fit shrink fit equipment. Background technique [0002] The disassembly methods of the existing mechanical equipment parts are generally manual, and the traditional disassembly tools are usually relatively simple tools, and the operation methods are relatively backward and far from perfect. Especially for the detachable parts that are shrink-fitted after heating, it is often impossible to complete the disassembly only by the hydraulic tension of the existing pull-off tool. Not only is the work difficult, labor-intensive and time-consuming, but also the work efficiency is low, and the workpiece is easily damaged. At present, almost all of the mechanical components installed by the shrink-fit assembly process in the traditional way will be damaged and s...

[0002] The disassembly methods of existing mechanical equipment parts are generally manual. The traditional disassembly tools are usually relatively simple tools, and the operation methods are relatively backward and far from perfect.

Especially for detachable parts that are shrink-fitted after heating, it is often impossible to complete the disassembly only by the hydraulic tension of the existing pull-off tools

Not only is the work difficult, labor-intensive and time-consuming, but also the work efficiency is low, and the workpiece is easily damaged

At present, almost all mechanical parts installed by the shrink-fit assembly process in the traditional way will be damaged and scrapped after disassembly
