Abstract
The utility model relates to a device for dismounting an interference fit pieces, and discloses an induction heating device for dismounting the interference fit pieces. The induction heating device is used for dismounting the inner workpiece and the outer workpiece which are in interference fit with each other, and comprises electromagnetic induction coils arranged on the outer side of the outer workpiece and function grooves formed in the end face of the outer workpiece, wherein magnetic induction heating blocks are arranged in the function grooves in an embedding manner. The magnetic induction heating blocks are arranged on the outer workpiece, so that an induction area is increased, the outer workpiece can be heated quickly, a gap is formed between the outer workpiece and the inner workpiece, and an easy-to-dismount purpose is achieved.
Description
Technical field
The utility model relates to a kind of provision for disengagement of interference fit part, be particularly related to a kind ofly for dismantling the induction heating apparatus of interference fit part, be applicable to the dismounting of the dish class such as bearing inner race, back-up ring, sealing ring, gear, shaft coupling, oil scraper ring and lopps interference fit part.
Background technology
Existing electromagnetic induction heater utilizes electromagnetic induction principle, externally in workpiece, produces induced-current, its heating is expanded, thereby, in generation gap, cooperation place, reach the purpose that is easy to dismounting.Due to eddy-current heating rapidly, evenly, cleanliness without any pollution, heating quality is high, and guarantees that workpiece is injury-free, this advanced person's method for dismounting just progressively replaces baking, oil and the method such as boils.In electromagnetic induction heating dismounting Interference Fitted Assemblies, at first outside workpiece receives electromagnetic induction, expanded by heating, and internal workpiece expanded by heating speed is slow, thereby makes outside workpiece and internal workpiece that gap occur, and can easily outside workpiece be disassembled.
The induction coil of current induction heater is custom-shaped, but in motor device, the outside workpiece shape be disassembled is varied, with existing induction heater heating dismounting, usually because not the mating of shape, induction area is too little, temperature can't be delivered to the outside workpiece that needs dismounting fast, cause being difficult to smooth and easy dismounting, even dismounting is not got off, and affects working effect.
Summary of the invention
The utility model relates to a kind of for dismantling the induction heating apparatus of interference fit part, externally on workpiece, increases the magnetic induction heat block, thereby increases induction area, and outside workpiece can be heated up rapidly, with internal workpiece, produces gap, reaches the purpose that is easy to dismounting.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of for dismantling the induction heating apparatus of interference fit part, for dismantling internal workpiece and the outside workpiece of interference fit, it is characterized in that, comprise the function trough arranged on the end face of the electromagnetic induction coil that is arranged on the described outside workpiece outside and described outside workpiece, be embedded with the magnetic induction heat block in described function trough.
Characteristics of the present utility model and further the improvement are:
Described internal workpiece is axle, on described axle, interference fit has the outside workpiece of annulus plate-like, the outer wall of the outside workpiece of described annulus plate-like is provided with annular electromagnetic induction coil, an end face of the outside workpiece of described annulus plate-like is provided with the function trough of two coaxial annulars, and in the function trough of described two annulars, correspondence is embedded with annular magnetic induction heat block.
Of the present utility model for dismantling the induction heating apparatus of interference fit part, externally on the function trough of workpiece, be embedded with the magnetic induction heat block, can accelerate electrothermal calefactive rate and the heating uniformity of outside workpiece, outside workpiece expanded by heating, produce gap with internal workpiece, thereby make outside workpiece and internal workpiece be easy to dismounting.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the overall structure schematic diagram for the induction heating apparatus of dismantling the interference fit part of the present utility model.
In figure: 1, internal workpiece; 2, outside workpiece; 3, electromagnetic induction coil; 4, magnetic induction heat block.
The specific embodiment
With reference to Fig. 1, it is the overall structure schematic diagram for the induction heating apparatus of dismantling the interference fit part of the present utility model.In figure, the internal workpiece 1 and outside workpiece 2 of this induction heating apparatus for dismantling mutual interference fit, comprise the function trough arranged on the end face of the electromagnetic induction coil 3 in the outside that is arranged on outside workpiece 2 and outside workpiece 2, be embedded with magnetic induction heat block 4 in function trough.
In the present embodiment, internal workpiece 1 is axle, on axle, interference fit has the outside workpiece 2 of annulus plate-like, the outer wall of the outside workpiece 2 of annulus plate-like is provided with annular electromagnetic induction coil 3, an end face of the outside workpiece 2 of annulus plate-like is provided with the function trough of two coaxial annulars, and in the function trough of two annulars, correspondence is embedded with annular magnetic induction heat block 4.
Of the present utility model for dismantling the induction heating apparatus of interference fit part, externally in the function trough of workpiece 2, be embedded with magnetic induction heat block 4, greatly accelerate the electrothermal calefactive rate of outside workpiece 2 under the effect of electromagnetic induction coil 3 and the heating uniformity, outside workpiece 2 expanded by heating speed are fast, internal workpiece 1 electrothermal calefactive rate is slow, outside workpiece 2 produces gap with internal workpiece 1, thereby makes between outside workpiece 2 and internal workpiece 1 to be easy to dismounting.This apparatus structure is simple, and reliability is strong, can greatly strengthen the efficiency of interference fit part dismounting.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art, under the enlightenment of this specification, in the situation that do not break away from the scope that the utility model claim is protected, can also make a variety of forms, and these all belong to the row of the utility model protection.
