General encoder for servo motor has integral structure in the market, and split-type structural is also arranged.Its integral structure comprises: the main body that plays spring bearing and main shaft effect; two bearings of supports main shaft and grating rotating; user installation connects the main shaft that motor shaft uses; the laminated spring that user's stationary body is used is arranged on the scrambler light emitting source on encoder main body, is arranged on the grating of deciding on main body; be arranged on the moving grating on the grating disc seat; be arranged on the circuit board on encoder main body, for the protection of the shell of scrambler inner structure, be used for the photoelectric cell of receiving optical signal.There is a lot of shortcoming and defect in tradition integral type encoder for servo motor, is in particular in: complex structure, and the space is large, is unfavorable for the installation of small-sized servomotor, and production process is many, and the cycle is long, and production and maintenance cost are high, and the cost of user installation is also very high.The structure of Split encoder comprises moving grating, grating seat, main body, be fixed on photoelectric cell of receiving optical signal on light emitting source on main body and circuit board and circuit board etc., its shortcoming is that installation accuracy is low, and debugging cycle is long, is not suitable for high precision and large batch of servomotor and uses.
It has structurally adopted the Principle of Mechanical Designing of integral type scrambler bearings main shaft motor integrated photoelectricity encoded servo device, debugging and installing and adopted the grating of Split encoder and the mode that the rotor axis of electric separate type is installed, absorbed both design marrow, make it occupy one seat in the competition of encoder for servo motor industry, and leading the trend of the market of following encoder for servo motor.
Summary of the invention
The purpose of this utility model is to provide the be combined into one photoelectricity encoded servo device of formula of a kind of and servomotor, this scrambler simple and reasonable, adopt scrambler main shaft and rotor axis of electric one, encoder main body and back end cover for motor one, its degree of saving installing space has surpassed Split encoder and integrated type ultrathin scrambler, production cost is lower than Split encoder, the cost of Installation and Debugging is lower than all encoder for servo motors, and improved the integral production efficient of scrambler and servomotor.
the purpose of this utility model is to realize like this, this scrambler comprises encoder main body, be arranged on the bearing on encoder main body, light emitting source and circuit board, be arranged on the photoelectric cell that is used for receiving optical signal on circuit board, be welded on the cable on circuit board, be arranged on the moving grating seat on rotor axis of electric and be arranged on the moving grating that moves on grating seat, it is characterized in that: described encoder main body uses and is integrally formed with it formula structure as back end cover for motor, described rotor axis of electric uses and is integrally formed with it formula structure as the scrambler main shaft, described moving grating seat is used for a racking grating and is fixedly connected on rotor axis of electric by two holding screws, be processed with one is used for the motor main body, the annular connected unit that is connected being installed in the outside of described encoder main body, also be processed with on encoder main body be used to the wire hole of drawing the motor cable line, described rotor axis of electric is arranged in bearing on encoder main body.
The utlity model has following advantage and good effect:
1, save to produce material and production cost: because the utility model scrambler adopts and the be combined into one design of formula of motor, directly will move grating is fixed on rotor axis of electric, utilize the rotation of motor to drive the rotation that scrambler moves grating, saved two bearings that conventional codec is used for connecting the scrambler main shaft of rotor axis of electric and supports the scrambler main shaft; Circuit board directly is fixed on motor rear end and covers, and back end cover for motor is used as original encoder main body, and the encoder main body and the client that have saved all elements of support scrambler install fixing required laminated spring; Selected the photoelectric cell of deciding grating with integrated circuit and optics on the photoelectric cell of signal receiving, saved again on optical element like this and decided grating; This product adopts without the shell design, is arranged on after on motor, debugging is completed, and directly buckles the servomotor guard shield and gets final product, and has saved the shell of conventional codec; Because saved a lot of elements, thus decrease the production cost of scrambler.
2, save cost of labor: because structure of the present utility model and motor are combined as a whole, so when scrambler is produced, also with the bearing of rotor axis of electric and rear end cap and rear end cap in the lump as the part production of scrambler, so starting material of motor self use that the user not only saves in the scrambler installation process, also improve greatly the production efficiency of motor, saved production and the cost of labor of motor.
3, the utility model coder structure advantages of simple, save the space, the special construction mode that its and motor are combined as a whole, the space that the script encoder for servo motor is shared drops to minimum, can satisfy the servomotor use of extra small external diameter ultrathin.
4, the breakthrough of the utility model maximum is that itself and motor share the frame mode of main shaft and main body.The structure of conventional codec needs the main body of a scrambler to support the structure of this scrambler, and two bearings are arranged on the main shaft that supports scrambler on encoder main body, the form that main shaft need the be arranged to tubular shaft installation that matches with rotor axis of electric, the structure of scrambler mechanical support part and the structure of motor have a lot of similarities, and the utility model is exactly to utilize both similarities a motor body to be transformed into the physical construction part of a scrambler.The rear end cap of motor is as the main body of scrambler, be used for supporting the structure of whole scrambler, the rear bearing of motor is as the spring bearing of scrambler, the armature spindle of motor supports the main shaft of grating part as scrambler, this kind of scrambler is to be provided with optics and circuit component on motor, it is become with motor is combined as a whole aly have a breakthrough scrambler.
