Abstract
The utility model discloses a fast remover for an interference fit metal sleeve pipe and the remover comprises a sleeve. The sleeve is matched with a shape of an outer metal sleeve pipe; the interior of the sleeve is provided with electromagnetic heating coils; magnetic fields of the electromagnetic heating coils are only adaptable to the outer metal sleeve pipe; the electromagnetic heating coils are connected with a controller; the sleeve is provided with a temperature detector; and the sleeve is connected with the controller. The fast remover for an interference fit metal sleeve pipe is advantaged in that the remover is heated and expanded by electromagnetic heating to the outer metal sleeve pipe; the heating and temperature rising speed is fast; and the internal metal sleeve pipe is free of effect of coils, so no heating is performed on the internal metal sleeve pipe. With the above structure, the fast remover for an interference fit metal sleeve pipe saves energy; better heating effect and temperature control are achieved; and product quality is improved. The fast remover for an interference fit metal sleeve pipe is simple in structure and convenient in usage.
Description
Technical field
The utility model relates to the quick withdrawing device of a kind of metal sleeve, and specifically the quick extractor of a kind of interference fit metal sleeve belongs to machining auxiliary equipment field.
Background technology
In machining and manufacture process, the mated condition of two or two above parts can be divided into roughly be slidingly matched, many grades such as interference fits and tight fit, interference fit belongs to a kind of in the what tight fit, the diameter of axle (key is wide) that is to say pairing is mutually wanted big what aperture (keyway), must adopt special tool(s) to push into, or utilize the characteristic of rising-heat contracting-cold, hole (keyway) heated, take advantage of the aperture and enlarge, be set to rapidly on the axle, back two parts of contraction to be cooled have just tightly fitted in one.Interference how much, on the processing drawing detailed description arranged.Can not take heating if meet some part, also axle (key) can be placed in the dry ice and cool off, effect is the same.But, because structural design, when removing interference fit workpiece is taken out, adopt jack etc. to be pressed into mode, this mode effort of not only taking a lot of work, and make bearing be subjected to a certain degree loss through regular meeting; And the employing mode of heating is to utilize thermal expansion to change tight fit into loose fit, but because in the process of heating, the inner ring of interference fit and outer ring all can expanded by heating, so the gap between its inner ring and the outer ring changes very for a short time, increased difficulty thereby make to take out.
Summary of the invention
In order to address the above problem, the utility model has designed the quick extractor of a kind of interference fit metal sleeve, this equipment makes himself thermal expansion by electromagnetism heating outer layer metal sleeve pipe, heat temperature raising is fast, self do not heat and the inner layer metal sleeve pipe is unaffected, save the energy, realized the control of better heating effect and temperature, improved product quality.
The technical solution of the utility model is:
The quick extractor of a kind of interference fit metal sleeve, described interference fit metal sleeve comprises outer layer metal sleeve pipe and inner layer metal sleeve pipe, described quick extractor comprises sleeve, described sleeve and outer layer metal sleeve-shaped match, be provided with electromagnetic heating coil in the described sleeve, the magnetic field of described electromagnetic heating coil only adapts with the outer layer metal sleeve pipe, described electromagnetic heating coil links to each other with controller, described sleeve is provided with hygrosensor, and link to each other with described controller, described controller is provided with control device, and the temperature value that obtains according to hygrosensor is controlled the work of electromagnetic heating coil.
Further, described sleeve bottom is provided with supporting seat, and described supporting seat is annular, and size matches with outer layer metal sleeve pipe bottom, makes things convenient for bearing inner race to take out in the annulus of supporting seat.
Electromagnetic heating technique is to make the bearing outer ring self-heating by electromagnetic induction principle, because itself does not generate heat electromagnetic heating coil, and be to adopt insulating materials and high-temperature cable manufacturing, have long service life, programming rate fast, need not advantage such as maintenance, reduced production cost greatly.
By variable-frequency electromagnetic heating principle, utilize electromagnetic induction principle to convert electrical energy into heat energy.With 220V or 380V, the alternating current of 50Hz converts the high-frequency high-voltage that frequency is 10-40KHz to, the high-frequency high-voltage current that changes flows through the alternating magnetic field that coil can produce the high speed variation at a high speed, when the magnetic line of force in the magnetic field can produce countless little eddy current during by magnetic conductive metal in metallic object, make the heating fast voluntarily of outer layer metal sleeve pipe.Simultaneously, cooperate dynamical attemperator, at utmost lower thermal losses, so just can reach the significantly effect of economize on electricity.Use this heating system, its energy conversion efficiency is up to 90-95%.
Advantage of the present utility model is: this equipment makes himself thermal expansion by electromagnetism heating outer layer metal sleeve pipe, heat temperature raising is fast, self do not heat and the inner layer metal sleeve pipe is unaffected, save the energy, realized the control of better heating effect and temperature, improved product quality, simple in structure, easy to use.
