Abstract
The invention discloses a modified large-scale electric permanent-magnet sucker, which has the advantages of high safety, precision and economy. The sucker comprises a cup body, a base, a magnetic cushion block, a magnetic pole and an electric brush system, wherein the circular cup body is supported on the base, and the central position of the circular cup body is provided with the electric brush system. The sucker is characterized in that sectorial magnetic units are distributed on the circular cup body uniformly and comprise reversible magnetic steel, field coils and the sectorial magnetic pole; the reversible steel and the field coils are arranged radially along the circular cup board to form a magnetic structure which is supported on the sectorial cup body; the sectorial magnetic pole is supported on the magnetic structure; and the magnetic cushion block is pressed on the end face of the sectorial magnetic pole.
Description
(1) technical field
The present invention relates to large-scale compound vertical round platform fixture for grinding machine, be specially a kind of improved type large-sized electric permanent-magnet suction disc.
(2) background technology
The existing used sucker of large-scale compound vertical round platform grinding machine, be generally magnechuck sticking workpiece and then workpiece carried out grinding, there is following defective in it: security is not high, and magnechuck need continue logical direct current could produce magnetic force, in case power down, workpiece easily flies out; Precision is not high, and coil produces heat because of continuing energising during magnechuck work, causes work top owing to temperature rise produces distortion, is not suitable for high-precision grinding processing; Economy is not strong, continues energising during magnechuck work, and power consumption is relatively big, and is less economical.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of improved type large-sized electric permanent-magnet suction disc, it is safe, precision is high, economy is strong.
It comprises circular disk body, base, magnetic cushion block, magnetic pole, brush-system, described circular disk body is supported on the described base, described circular disk body home position is equipped with brush-system, it is characterized in that: be evenly equipped with fan-shaped magnetic conduction unit on the described circular disk body, described magnetic conduction unit comprises reversible magnet steel, magnet exciting coil, fan-shaped magnetic pole, described reversible magnet steel, magnet exciting coil is radially arranged along circular disk body and is constituted a magnetic conduction construction, described magnetic conduction construction is supported on the described circular disk body, described fan-shaped pole supports is on magnetic conduction construction, and described magnetic cushion block press-fits in described fan-shaped magnetic pole upper surface.
It is further characterized in that: described brush-system is specially radially contact rotary type brush-system, described brush-system top is pressed with the waterproof end cap, described brush-system bottom connects described base by locating shaft, and described base is specially box-type ironcasting base.
In the said structure of the present invention, owing to be evenly equipped with fan-shaped magnetic conduction unit on the described circular disk body, described magnetic conduction unit comprises reversible magnet steel, magnet exciting coil, fan-shaped magnetic pole, described reversible magnet steel, magnet exciting coil are radially arranged along circular disk body and are constituted a magnetic conduction construction, described magnetic conduction construction is supported on described circular disk body, described fan-shaped pole supports is in magnetic conduction construction, and described magnetic cushion block press-fits in described fan-shaped magnetic pole upper surface; When it magnetizes operation, feed the pulse direct current of short time in the magnet exciting coil, produce high-intensity magnetic field thus with the reversible magnet steel saturated magnetization that coil surrounded, this moment, reversible magnet steel just became strong magnetic source, by magnetic pole magnetic force is directed on the magnetic cushion block, and then the sticking workpiece is processed; During its degaussing operation, just feed the progressively alternating current of decay in the magnet exciting coil, consequent decay electromagnetic field can be with the reversible magnet steel demagnetization that coil surrounded, and this decay electromagnetic field can remove remanent magnetism to the workpiece of sucker institute sticking.It does not need electricity consumption in process, so even power down suddenly in process, chuck surface can not lose magnetism yet, and guarantees the security of process, and it is safe; Because it need not switched in process, so there is not the problem of sucker inner heat, can solve the problem of thermal deformation preferably, guarantee high-precision grinding, its precision height; Because consumed power not substantially in the sucker course of work is saved cost, so its economy is strong.
