The encoder comprises a housing, a rubber molded bushing, a circuit board with an electric appliance element, a movable grating, a fixed grating, a movable grating base, a first bearing, a light-emitting diode, a main body support, a second bearing, a hollow shaft and a leaf spring. The encoder is characterized by also comprising a light-emitting diode sleeve, which is sleeved outside the light-emitting diode and is arranged above the main body support. The light-emitting diode on the encoder is mounted in an embedded manner, thereby saving the space, improving the product positioning precision, solving the problems that in the prior art light-emitting diodes are fixed by using circuit boards and the fixation is unstable and unreliable, and achieving the effects of compactness, small space, simplicity, reasonableness and convenient and rapid installation and adjustment. Compared with conventional encoders, the encoder of the utility model is lighter, thinner and cheaper, requires smaller mounting space and is adapted to the small and powerful requirements of the modern industry.
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 the servomotor, this basic function of encoded servo device is the same with conventional coders, the increment of rotation scrambler is the output pulse when rotating, calculate its position by counting equipment, motionless or when having a power failure when scrambler, rely on the memory internal of counting equipment to remember the position, in addition, the encoded servo device also has with the different place of conventional coders, that is exactly servomotor most is synchronous motor, need to know the position of magnetic pole of rotor in the time of synchronous motor startup, can start servomotor by high-torque like this, need to join in addition the current location that several signals come detection rotor like this, such as incremental the signals such as UVW just be arranged.
The domestic encoded servo device manufacturer that do not produce a few years ago, large multi-servomotor factory all selects external Heidenhain and Duo Mo river encoded servo device, 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 subjected in recent years supports to develop with each large research institute, introduction of foreign technology, present domestic encoded servo device technology maturation, price has more abroad reduced a lot, domestic each large servomotor manufacturer also selects domestic encoded servo device, 1 year needs sales volume of dimensions of market hundreds of thousands platform mostly.
Traditional scrambler is because unreasonable structure, 1., luminotron is fixing insecure, unstable the circuit board fixed form is adopted in the installation that is luminotron, has a lot of shortcoming and defect, is in particular in:, 2. so that the one-piece construction of scrambler is 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, can't substitute high-end same kind of products at abroad.
Summary of the invention
The objective of the invention is to provide a kind of permanent magnetic servo high-speed electric expreess locomotive ultrathin scrambler, the mounting means of luminotron adopts embeddedly on this scrambler, not only saves the space but also once added the product orientation precision, and substitute needed with the fixing luminotron and unstable of circuit board in the past, the problem such as unreliable, compactness, the 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, decide grating, moving grating seat, the light emitting diode pipe box, clutch shaft bearing, light emitting diode, the main body bearing, the second bearing, tubular shaft and laminated spring, described circuit board with electric elements, moving grating, decide grating, moving grating seat, the light emitting diode pipe box, clutch shaft bearing, light emitting diode, the main body bearing, consist of encoder main body after the second bearing and the tubular shaft assembling, 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 the shell side, it is characterized in that: described light emitting diode is set with in the light emitting diode pipe box, the light emitting diode pipe box be arranged on the main body bearing above.
The present invention has the following advantages and good effect:
1, the present invention is owing to adopt 6800 bearings of thinner less external diameter, simultaneously make into the mounting means of luminotron embedded, not only save the space but also once added the product orientation precision, substitute needed with the fixing luminotron and unstable of circuit board in the past, the problem such as unreliable, compactness, the space is little, advantages of simple is debug 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 the 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 the main body bearing, 1., that bearing accuracy 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 need not to be screwed the saving installation time; 3., can make light emitting diode and metallic main body bearing insulation.
