Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] refer to figure 1 As shown, the present invention provides a non-contact magnetic positioning encoder for a deviation correction system, which includes a reduction gear device 2 and a circular encoder circuit board 3, and the reduction gear device 2 and the encoder circuit board 3 pass through a bolted Three copper columns 4 (two are shown in the figure) are fixedly connected, and the three copper columns 4 are evenly distributed on the encoder circuit board 3 at intervals of 120 degrees:
[0024] The reduction gear device 2 includes a circular reduction gear base 21 that is sleeved on the outside of the motor shaft 5. There is no contact between the reduction gear base 21 and the motor shaft 5. The reduction gear device 2 passes through the reduction gear base. 21 is fixed on the tail end of the motor 1 to support the entire magnetic p...

The invention belongs to the technical field of automation control application, and specifically relates to a non-contact magnetic positioning encoder for a deviation correction system. A reduction gear device and an encoder circuit board are arranged, a rotating shaft of a motor rotates to drive a reduction gear set to rotate in a deceleration mode, so that an output shaft of the reduction gear set synchronously rotates with an electromagnet, a magnetic chip determines the change of the position of a motor screw rod by sensing the magnetic variation of the electromagnet, the position change is transmitted to the encoder for recording and saving, the travel range of a deviation correction actuator is limited through the saved position value of the encoder, the hard contact between a screwnut on the deviation correction actuator and a mechanical limit is avoided, so that the screw rod is protected, the motor and the motor drive are also protected, and the phenomenon that the actuator is stuck by the mechanical limit and is further blocked and burnt out can be avoided. The non-contact magnetic positioning encoder for the deviation correction system has high limiting accuracy, is installed on the back end of the motor, and has the advantages of compact structure, small space occupation and very convenient disassembly and assembly.
Description
technical field [0001] The invention belongs to the technical field of automatic control application, in particular to a non-contact magnetic positioning encoder for a deviation correction system. Background technique [0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. The encoder converts the angular displacement or the linear displacement into an electrical signal, and the former is called a code disc, or a yardstick. According to the readout method, the encoder can be divided into contact type and non-contact type; according to the working principle, the encoder can be divided into incremental type and absolute type: the incremental encoder converts the displacement into a periodic electrical signal, Then convert this electrical signal into counting pulses, and use the number of pulses to represent the magnitude of the displacement; each position of the absolute encoder...
