Abstract
The invention relates to an encoder, also named speed and displacement sensor, in particular to an ultra-thin encoder of a permanent magnet servo high-speed motor. The ultra-thin encoder comprises a shell, a rubber-formed wire protecting bushing, a circuit board provided with electric elements, a movable raster, a fixed raster, a movable raster base, a first bearing, a light emitting diode, a main support, a second bearing, a hollow shaft and a blade spring. The ultra-thin encoder of the permanent magnet servo high-speed motor is characterized in that the ultra-thin encoder further comprises a light emitting diode sleeve, the light emitting diode is sleeved with the light emitting diode sleeve, and the light emitting diode sleeve is arranged on the main support. Due to the fact that the light emitting diode of the encoder is installed in an embedded mode, space is saved, production positioning accuracy is improved, and the problem that in the prior art, a light emitting diode is fixed by means of a circuit board, and fixation is unstable and unreliable is solved. The ultra-thin encoder of the permanent magnet servo high-speed motor is compact, small in occupied space, simple, reasonable, and convenient and fast to assembly and adjust. Compared with existing encoders, the ultra-thin encoder of the permanent magnet servo high-speed motor is lighter, thinner and lower in cost. The installation space is small, and requirements of the modern industry for smaller size and more powerful function are met.
Description
Technical field
The present invention relates to a kind of scrambler, claim again speed and displacement transducer, specifically the ultrathin scrambler of a kind of permanent magnetic servo high-speed electric expreess locomotive.
Background technology
Encoder for servo motor is mounted in a kind of sensor that is used for measuring position of magnetic pole and servomotor corner and rotating speed on servomotor, this basic function of encoded servo device is the same with conventional coders, increment of rotation scrambler is exported pulse when rotating, by counting equipment, calculate its position, when scrambler is motionless or have a power failure, rely on the memory internal of counting equipment to remember position, in addition, encoded servo device also has with the different place of conventional coders, that is exactly servomotor most is synchronous motor, in the time of synchronous motor startup, need to know the position of magnetic pole of rotor, can start servomotor by high-torque like this, need to join in addition the current location that several signals carry out detection rotor like this, such as incremental, just there are signals such as UVW.
The domestic encoded servo device manufacturer that do not produce a few years ago, multi-servomotor factory all selects external Heidenhain and Duo Mo river encoded servo device greatly, external encoded servo device is expensive, and specifications and models, volume size are single, causes that domestic servomotor cost is high, motor type is few; The domestic country that was subject in recent years supports that He Ge great research institute develops, introduction of foreign technology, present domestic encoded servo device technology maturation, price has more abroad reduced a lot, domestic Ge great servomotor manufacturer also selects domestic encoded servo device, 1 year needs sales volume hundreds of thousands platform of dimensions of market mostly.
Traditional scrambler is due to unreasonable structure, 1., luminotron is fixing insecure, unstable the installation that is luminotron adopts circuit board fixed form, has a lot of shortcoming and defect, is in particular in:, 2., make the one-piece construction of scrambler not compact, 3., weight is larger the space of installing is large, and it is convenient not and quick to debug,, thickness is large, cost is high, is not suitable with the little demand with better function of volume of modern industry requirement, cannot substitute high-end same kind of products at abroad.
Summary of the invention
The object of the invention is to provide a kind of permanent magnetic servo high-speed electric expreess locomotive ultrathin scrambler, on this scrambler, the mounting means of luminotron adopts embeddedly, not only saves space but also once added product orientation precision, substitutes and needs with the fixing luminotron and unstable of circuit board in the past, the problem such as unreliable, compactness, space is little, advantages of simple, debug convenient and swift, lighter with scrambler comparison weight in the past, thickness is thinner, and cost is lower.The space of installing is little, has adapted to the little demand with better function of volume of modern industry requirement.
The object of the present invention is achieved like this, this this scrambler comprises shell, rubber moulding wire bushing, circuit board with electric elements, moving grating, determine grating, moving grating seat, light emitting diode pipe box, clutch shaft bearing, light emitting diode, main body bearing, the second bearing, tubular shaft and laminated spring, the described circuit board with electric elements, moving grating, determine grating, moving grating seat, light emitting diode pipe box, clutch shaft bearing, light emitting diode, main body bearing, after the second bearing and tubular shaft assembling, form encoder main body, outer cover suit is in the outside of encoder main body, laminated spring be arranged on encoder main body below, rubber moulding wire bushing is arranged on shell side, it is characterized in that: described light emitting diode is set with in light emitting diode pipe box, light emitting diode pipe box be arranged on main body bearing above.
The present invention has the following advantages and good effect:
1, the present invention is owing to adopting 6800 bearings of thinner less external diameter, the mounting means of luminotron is made into embedded simultaneously, not only save space but also once added product orientation precision, substitute and to need with the fixing luminotron and unstable of circuit board in the past, the problem such as unreliable, compactness, space is little, advantages of simple, debugs convenient and swift.
2, relatively weight is lighter for the present invention and scrambler in the past, and thickness is thinner, and cost is lower.The space of installing is little, has adapted to the little demand with better function of volume of modern industry requirement.
3, the present invention adopts light emitting diode pipe box to be applied on the ultrathin scrambler of permanent magnetic servo high-speed electric expreess locomotive, be used for installing the support and connection between luminotron and main body bearing, 1., that positioning precision is installed is high this light emitting diode pipe box has following effect:, reduced light emitting diode the not positive situation that occurs is installed; 2., this luminous pipe box is without being screwed, and saves installation time; 3., can make light emitting diode and metallic main body bearing insulation.
