Combined type lifting induction heating disassembling-assembling machine

Abstract

The invention relates to a combined type lifting induction heating disassembling-assembling machine which comprises a hydraulic pull-ejection device, a control device and a lifting adjustment device. The lifting adjustment device comprises a frame and an adjusting lead screw, and the hydraulic pull-ejection device is connected with the frame through the adjusting lead screw; the hydraulic pull-ejection device comprises a hydraulic jack, a pull rod, a pull hook and an inner shell, the pull hook is connected with the pull rod through a locating sleeve, and the pull rod is connected with the inner shell through a pull rod bearing sleeve; the inner shell is of a hollow cylindrical structure, the outer circumference of the inner shell is provided with an electromagnetic coil, the electromagnetic coil is connected with the control device through a wire, and the outer surface of the electromagnetic coil is provided with an outer shell. The combined type lifting induction heating disassembling-assembling machine is formed by combining an electric induction heating device and a hydraulic ejection system, the height can be adjusted at will, and the combined type lifting induction heating disassembling-assembling machine is suitable for wheel systems difficult to disassemble due to interference fit. The combined type lifting induction heating disassembling-assembling machine can be widely used for heating disassembling of annular hole-shaped metal such as bearings, main wheels, bushes, shaft sleeves, diameter rings, sliding wheels, retraction rings and shaft couplings, and the aim of interference disassembling is achieved through heating expansions.

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
