Abstract

The invention relates to an on-line demagnetization circuit for fast response bearing rings, which belongs to the technical field of bearing manufacturing and includes an electronic starting circuit, a delay control circuit, and a voltage-controlled voltage regulator. The electronic starting circuit includes: There are a proximity switch, a photoelectric coupler and a first resistor, and the proximity switch is arranged on the feeding channel of the feeding mechanical device; and a secondary side starting branch circuit is provided with an output terminal of a photocoupler, a second resistor and a switch tube in series, and its basic The pole is connected to the second resistor, and the collector is connected to the power supply; the delay control circuit includes a parallel charging branch and a discharging branch, and a capacitive element is arranged in series in the charging branch, and the capacitive element is connected to the emitter of the switch tube; The low-voltage input end of the voltage-controlled voltage regulator is connected with a capacitive element, and the output end of the voltage-controlled voltage regulator is connected with a demagnetization coil. The demagnetization circuit of the present invention can eliminate the magnetism of the bearing ring in the demagnetization coil under the state of the largest possible magnetic field intensity, and realize effective and reliable demagnetization.

Description

technical field [0001] The invention belongs to the technical field of bearing manufacturing, and in particular relates to an online demagnetization circuit for fast response bearing rings. Background technique [0002] Fully automatic bearing production lines have been widely used in the bearing manufacturing industry, and many of the grinding equipment on the bearing production line use electromagnetic coreless fixtures as tooling to support the bearing rings, and the bearing rings are adsorbed on the magnetic poles for grinding . After the grinding process is completed, some residual magnetism remains on the bearing ring, and the unloading mechanical device will move the bearing ring into the discharge channel, and the bearing ring will roll down along the inclined discharge channel, and enter the Go to the demagnetization device for demagnetization. After the bearing ring is demagnetized, it will automatically leave the demagnetization device and enter the next processi...
