Abstract
The invention relates to a circular electro-permanent magnetic chuck for a vertical lathe, in particular to a magnetic fixture for a vertical lathe for realizing rapid machining by way of taking the place of grinding by turning. The circular electro-permanent magnetic chuck for a vertical lathe comprises a chuck body, magnetic poles, a magnetic steel, a magnet exciting coil and a magnetic cushion, wherein a plurality of strip-shaped holes are arranged above the chuck body, the magnetic poles are pressed on the magnetic steel, and the magnet exciting coil is arranged on an outer ring of the magnetic steel; the magnetic cushion is arranged above the magnetic poles, the magnetic cushion and the magnetic poles are integrated and arranged in the strip-shaped holes above the chuck body by bolts, and the wires of the magnetic poles are led out from the chuck body. The magnetic poles are straight-strip-shaped magnetic poles with same width. The two adjacent polarities of the straight-strip-shaped magnetic poles are opposite, and even magnetic poles are arranged on a same circumference in pairs. The invention has strong suction force, can satisfy the requirement for machining, has good retentivity of accuracy and stable state in the process of machining, can satisfy the requirement for finish machining, exempts the process of grinding, does not cause the phenomenon of divergent magnetic field, and can effectively avoid the influence of magnetic fields on cutting tools and iron filings in the process of machining.
Description
Technical field
The present invention relates to the circular electric permanent-magnet suction disc of a kind of vertical lathe, specifically vertical lathe uses magnetic clamp, is used to realize with the quick machining of car for mill.
Background technology
Along with the development of wind-powered electricity generation industry, wind-powered electricity generation enterprise strengthens the demand of wind power bearing at present, and the wind power bearing processing industry is badly in need of a kind of high accuracy, high efficiency turning clamp for machining.The one, solve the low problem of working (machining) efficiency, need to realize with finish turning replaceable operation chain grinder preface, the target that effectively reduces process time; The 2nd, need to solve in the traditional vehicle process the inevitable problem that produces radial deformation during because of chuck clamping thin-walled parts; The 3rd, solve a clamping and just can finish the problem that multiaspect is processed, to prevent producing mismachining tolerance because of multiple clamping.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of stronger pretightening force that has is provided, can satisfy the demand of turning processing; Precision stability is good in process, and is in stable condition, can satisfy the fine finishining demand, exempts the circular electric permanent-magnet suction disc of vertical lathe of grinder preface.
According to technical scheme provided by the invention, vertical lathe comprises disk body, magnetic pole, magnet steel, magnet exciting coil with circular electric permanent-magnet suction disc, described disk body top is provided with many bar holes, magnetic pole is pressed on the magnet steel, on the magnet steel outer shroud magnet exciting coil is installed, described magnetic pole top is installed the magnetic pad and is formed one, is installed in screw in the bar hole of disk body top, and the electric wire of magnetic pole is drawn disk body.
Described magnetic pole adopts wide vertical bar magnetic pole.Adjacent two polarity of described vertical bar magnetic pole are opposite, and the magnetic pole that distributes on the same circumference is an even number, occur in pairs.
Compared with the prior art the present invention has the following advantages:
1, simple, compact and reasonable for structure, have stronger pretightening force, can satisfy the demand of turning processing; 2, precision stability is good in process, and is in stable condition, can satisfy the fine finishining demand, exempts grinding process; 3, only there are end face pretightening force and supporting force, do not have radially clamping force, no radial deformation; 4, single face sticking does not hinder the processing to all the other each positions beyond the sticking face, can realize the requirement that No. a time clamping is finished multiple working procedure fully; 5, the universal performance that has electric permanent-magnet suction disc, safety, high accuracy, energy-conservation.
Description of drawings
Fig. 1 is a structure user mode schematic sectional view of the present invention.
Fig. 2 is Fig. 1 vertical view (a magnetic pole distribution schematic diagram).
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1~shown in Figure 2: comprise disk body 1, magnetic pole 2, magnet steel 3, magnet exciting coil 4, magnetic pad 5, rest pad 6 and part 7; Described disk body 1 top is provided with many bar holes, magnetic pole 2 is pressed on the magnet steel 3, magnet exciting coil 4 is installed on magnet steel 3 outer shrouds, described magnetic pole 2 tops are installed magnetic pad 5 and are formed one, be installed in screw in the bar hole of disk body 1 top, and the electric wire of magnetic pole 2 drawn disk body 1, on the described disk body 1 socket 8 is housed.
As shown in Figure 2, the magnetic pole 2 on the disk body 1 arranges that according to the big subsection of specification the inner ring magnetic pole number is few from the inside to surface as can be seen, and the outer ring number of magnetic poles is many, and each supporting-point spacing is consistent substantially.Magnetic pole 2 all is wide vertical bar magnetic pole, and by the magnetic field intensity basically identical that magnet steel inspires, the suction that is produced will evenly distribute.
When controller magnetizes operation, just feed the pulse direct current of short time in the magnet exciting coil 4, produce high-intensity magnetic field thus with reversible magnet steel 3 saturated magnetizations that coil surrounded, this moment, reversible magnet steel just became strong magnetic source, by magnetic pole 2 magnetic force is directed on the magnetic pad 5, magnetic pad 5 tops are placed rest pad 6 and part 7 successively, and then the sticking part is processed.
In controller when operation demagnetization, just feed the progressively alternating currents of decay in the magnet exciting coil 4, consequent decay electromagnetic field can be with reversible magnet steel 3 demagnetizations that magnet exciting coil surrounded, and this decay electromagnetic field can remove remanent magnetism to the workpiece of sucker institute sticking.
Adjacent two polarity of the vertical bar magnetic pole that sucker disk body 1 is adopted are opposite, the magnetic pole that distributes on the same circumference is an even number, occurs in pairs, and this structure is better restrictive to magnetic field, can not cause magnetic field to disperse, can effectively avoid in the process magnetic field influence to cutter and iron filings.
