The movable grating part comprises a glass movable grating and a movable grating base supporting the glass movable grating, a motor mounting hole is processed in the movable grating base, and two locking screws are correspondingly arranged on a side wall of the mounting hole. The circuit supporting part comprises a main body, a circuit board arranged on the main body and a light-emitting source installed on the main body. The circuit board outputting electric signals is provided with a photocell for receiving optical signals, and user mounting holes are symmetrically formed in the main body. The encoder is simple and reasonable in structure, a bearingless spindle-less structure mode with the movable grating and the main body split is adopted, the encoder saves space and is convenient to assemble, the production cost of the encoder is reduced, and the user's maintenance cost is also reduced.
Description
Technical field
The present invention relates to a kind of encoder for servo motor, claim again speed and displacement transducer, a kind of without the split type encoder for servo motor of bearing specifically.
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, calculate its position by counting equipment, in the time that 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 the place different with conventional coders, that is exactly servomotor most is synchronous motor, when synchronous motor startup, need to know the position of magnetic pole of rotor, can start servomotor by high-torque like this, several signals need to be joined in addition like this and come the current location of detection rotor, just there are signals such as UVW such as incremental.
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; Domestic be subject in recent years country support and Ge great research institute develop, 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.
On market, general encoder for servo motor is integral structure now, its concrete structure comprises: the encoder main body that plays connection bearing and main shaft effect, drive two bearings of main shaft and grating rotating, user installation connects the main shaft using, user fixes laminated spring used, be arranged on the scrambler light emitting source on encoder main body, be arranged on main body and determine the grating of determining on grating seat, be arranged on the moving grating on moving grating seat, be arranged on the circuit board on encoder main body, for the protection of the shell of scrambler inner structure, moving grating seat is connected with main shaft for a racking grating, photoelectric cell for receiving optical signal is set in circuit board.There is a lot of shortcoming and defect in above-mentioned traditional encoder for servo motor, is in particular in: complex structure, and space is large, be unfavorable for the installation of small-sized servomotor, and production process is many, the cycle is long, production cost and cost of labor are all very high, and maintenance cost is also along with increase.
Summary of the invention
The object of the invention is to provide a kind of without the split type encoder for servo motor of bearing, this coder structure advantages of simple, adopt without bearing, without the frame mode of main shaft, moving grating and main body split, save space, easy to assembly, save the production cost of scrambler self, also save user's maintenance cost.
The object of the present invention is achieved like this, this scrambler is by moving grating part and circuit supporting part two parts form, described moving grating department divides and comprises that glass moves grating, the moving grating seat of the moving grating of support glass, on described moving grating seat, be processed with motor mounting hole, on the sidewall of mounting hole, correspondence arranges two lock-screws; Described circuit supporting part comprises main body, is arranged on the circuit board above main body, is arranged on the light emitting source in main body, is provided with the photoelectric cell of receiving optical signal on the circuit board of output electrical signals, symmetrically arranged user installation hole in main body.
The present invention has the following advantages and good effect:
1, save and produce material: because scrambler of the present invention adopts without bearing design, directly moving grating part is arranged on the main shaft of motor, utilize the rotation of motor to drive the rotation of the moving grating of scrambler, saved conventional codec for connecting the main shaft of motor and driving main shaft to rotate two bearings; In main body, be provided with two user installation holes, so saved again the fixing required laminated spring of client; On the photoelectric cell of signal, select the photoelectric cell of determining grating with integrated circuit and optics receiving, on optical element, saved again and determined grating like this; This product adopts without shell design, after being arranged on and having debugged on motor, directly buckles servomotor guard shield, has saved the shell of conventional codec.
2, save cost of labor: because scrambler of the present invention has been saved the part such as bearing, main shaft, so saved cost of labor in machining, in the time of assembling, owing to having reduced assembly process, also saved cost of labor, and this kind of encoder debugging saves time very much.
3, the moving grating of scrambler of the present invention is directly installed on electric machine main shaft, drives without bearing, so reduced the probability damaging, has extended the serviceable life of scrambler.
4, coder structure advantages of simple of the present invention, saving space, due to without bearing and main shaft, can accomplish external diameter and thickness that traditional encoder for servo motor is not accomplished, greatly reduce the space of servomotor installation scrambler, the servomotor that can meet extra small external diameter ultrathin uses.
