The utility model discloses a digital pulse rotary sensor, and particularly relates to an magnetic electricity rotary encoder; the encoder comprises an encoder shell, a circuit board, a encoder main body, a main shaft and a bearing, and is characterized in that the magnetic electricity rotary encoder further comprises a magnetic pole arranged at the central position of the end part of the main shaft, and a magnetic induction chip arranged on the circuit board and arranged corresponding to the magnetic pole 2. In the utility model, the photoelectric principle structure of the original encoder is changed and replaced by a magnetic electricity type structure; simultaneously, the easily-broken glass accessories such as code disc slot are cancelled, the magnetic block is used for replacing the light emitting element, a programmable chip is used for receiving, and the pulse signals are sent out through circuit processing. The magnetic electricity rotary encoder has the advantages of being simple in mechanism and easy to debug, simplifying the whole mounting process, being applicable to great high-low temperature difference and high in vibration resistance and impact resistance, saving raw material, and the like.

Description

Magnetic-electric rotary encoder

Technical field

The utility model discloses a kind of digit pulse rotating detector, a kind of specifically magnetic-electric rotary encoder, this scrambler can be widely used in fields such as Industry Control, machine-building, boats and ships, weaving, printing, Aeronautics and Astronautics, radar, communication, military project.

Background technology

Scrambler is a kind of rotating detector that angle displacement is converted to a succession of digit pulse.Its basic structure is made up of luminescent device, code-disc, slit, receiving element.When the scrambler axle drove the code-disc rotation, the light that sends through light-emitting component was cut into interrupted light by code-disc, slit and is received element and receives, and produces initialize signal, this signal after subsequent conditioning circuit is handled, output signal.The precision of rotary encoder depends on machinery and electric factor, and these factors have: the inexactness of optical disc eccentricity, bearing off-centre and opticator.Traditional photoelectric encoder is because its code-disc is generally glassware, and is frangible, has inborn shortcoming aspect anti-vibration, and degree of protection is low, and operating temperature range is narrow, and-20 0C is to+50 0C, and code-disc when delineation accuracy requirement height, difficulty is big.The assembly cost height, production efficiency is low.During assembly and adjustment for bearing, main shaft, main body, the cooperation between the optical device etc. is strict, difficulty is big reducing on the error, production efficiency is low.

Summary of the invention

The purpose of this utility model is to adopt the magnetoelectricity principle, the magnetic-electric rotary encoder of the high and low cost of a kind of reliability is provided, it has solved, and traditional photoelectric encoder code-disc is frangible, accuracy requirement is high, complicated in mechanical structure, debug shortcomings such as process is loaded down with trivial details, select for use the magnetoelectricity integrated chip to realize the generation of signal, receive and handle, save the debug process of traditional photo-electric complexity, increase substantially the performance of production efficiency and product.

The purpose of this utility model is to realize like this, this scrambler comprises scrambler shell, circuit board, scrambler main body, main shaft, bearing, it is characterized in that: it also comprises a magnetic post that is arranged on the spindle nose center, and one is arranged on the magnetic induction chip that corresponding magnetic post 2 is provided with on the circuit board.

The center of described magnetic post and magnetic induction chip point-blank, magnetic post and magnetic induction chip maintain suitable distance when being provided with.

The utility model has changed the theory structure of original encoding device photo-electric, adopt the magneto-electric structure to replace, breakaway glass annexes such as code-disc slit have been cancelled simultaneously, replaced luminous original paper with the magnetic post, receive by programmable chip again, spread out of pulse signal through processing of circuit, have the following advantages and good effect:

1, saves the time of debuging after the change structure, simplified resetting difficulty, improved work efficiency.

2, owing to cancelled breakable element such as code-disc, slit, avoided using because of slit, code-disc crushing reasons influence product.

3, can adapt to the bigger environment of the height temperature difference, operating temperature range is wide, and serviceability temperature reaches-45 0C-125 0C.

4, design is firm, the degree of protection height, and degree of protection can reach IP64, can resist high strength bump and vibrations

5, physical construction is simple, has saved starting material, reduces purchase cost.

Description of drawings

Fig. 1 is a magnetic-electric rotary encoder one-piece construction synoptic diagram.

Embodiment

Shown in accompanying drawing 1: this scrambler comprises scrambler shell 1, circuit board 4, scrambler main body 5, main shaft 6, bearing 7, it is characterized in that: it comprises that also 2, one on a magnetic post that is arranged on center, main shaft 6 end is arranged on the magnetic induction chip 3 that corresponding magnetic post 2 is provided with on the circuit board 4.

The center of described magnetic post 2 and magnetic induction chip 3 point-blank, magnetic post 2 and magnetic induction chip 3 maintain suitable distance H when being provided with, guarantee H+0.05mm or H-0.05mm.

During use this scrambler is fixed on survey on the object, the object main axis rotation of surveying drives the scrambler main axis rotation simultaneously, magnetic post 2 is from N, the S utmost point sends the signal of respective angles position magnetic induction line, magnetic induction chip 3 receives and induction magnetic induction line signal, this magnetic induction chip 3 is programmable chips, can require to enroll distinct program according to difference, magnetic induction chip 3 is placed in the circuit board center, with magnetic post 2 correspondences that are placed on the scrambler alignment of shafts, receive the lines of magnetic induction that spreads out of by magnetic post 2 by circuit supply magnetic induction chip 3 and produce magnetoelectric effect, and spread out of pulse signal, around magnetic induction chip 3, corresponding subsequent conditioning circuit is arranged,, realize different output forms according to different requirements, replace the theory structure of photo-electric fully, thereby realized purpose of the present invention.
