The process comprises the following steps: firstly mounting a stator winding, a rotor, a front end cover and a rear end cover; passing direct current through the stator winding; finding an actual zero point of an encoder by using an encoder zero point detector; mounting the encoder in a motor rear cover; passing the direct current through the brake, opening a band-type brake and mounting the brake in a brake shell to finish the assembly. According to the process, the assembly accuracy for assembling the encoder on the motor can be effectively improved. The process relates to the technical field of motors.
Description
Technical field
The present invention relates to a kind of motor stamping, relate more specifically to the present invention relates to a kind of AC servo motor assembly technology with brake.Belong to electric motors.
Background technology
AC servo motor due to its positioning precision high, rotating speed is steady, the features such as overload capacity is strong, have been widely used in lathe, printing equipment, packaging facilities, Weaving device, robot, automatic production line etc. and have required in relatively high industry craft precision, working (machining) efficiency and functional reliability.
In the servo system of complete set, high position precision is one of them key character, the assembly precision that the factor affecting positioning precision comprises the control precision of driver, encoder feedback precision and is assemblied in by encoder on motor.
Existing servomotor, for meeting real requirement mostly with electricity loss brake, is generally installed between motor body and encoder.Due to brake electric declutch after still with certain resistance, use traditional assembly technology, when motor and encoder can be caused to attach together, there is comparatively big error in the location of rotor, thus cause can produce comparatively big error relative to the location of motor rotor magnetic steel position the zero point of encoder.
Summary of the invention
The invention discloses a kind of AC servo motor assembly technology with brake, be intended to installation site on motor body and erection sequence by adjustment brake and encoder, effectively can improve the positioning precision of zero point relative to motor rotor magnetic steel position of encoder.
For reaching above object, the present invention takes following technical scheme to be:
With an AC servo motor assembly technology for brake, it comprises the following steps:
(1) installation of stator winding, rotor, front end housing, rear end cap is first completed;
(2) pass to direct current to stator winding, then the magnetomotive force that produces of stator winding and the magnetomotive force of rotor magnetic steel interact the synthesis magnetomotive force produced, and rotor magnetic steel are locked in a certain fixed angle of radial circumference, determine the dead-center position of rotor magnetic steel;
(3) encoder zero-crossing detector is utilized to find the actual zero point of encoder;
(4) make the actual zero point of encoder corresponding consistent with the dead-center position of rotor magnetic steel, encoder is installed on the Rotor terminal of locked position; By the Rotor terminal finding the encoder at zero point to be installed on locked position, so the anglec of rotation of encoder and dead-center position just represent the anglec of rotation and the dead-center position of rotor magnetic steel;
(5) mounted motor back cover;
(6) brake passes to direct current, opens band-type brake, is installed on by brake in brake casing, completes assembling.
On technique scheme basis, as follows particularly:
In (1) step, comprising: press-fited by stator winding in motor case, press-fited by the fore bearing of rotor in the bearing chamber of front end housing, rotor passes stator winding, mounted motor front end housing, mounted motor rear end cap.
In (2) step, the direct current of described stator winding is 5V direct current; Wherein the U of stator winding connects DC power anode, and V, W connect DC power cathode.
In (6) step, brake passes to 24V direct current.
The invention has the advantages that:
Direct current is passed to stator winding, now the magnetomotive force that produces of stator winding and the magnetomotive force of rotor magnetic steel interact the synthesis magnetomotive force produced, rotor magnetic steel is locked in a certain fixed angle of radial circumference, to determine the dead-center position of rotor magnetic steel, brake is not assembled due on now rotor, now epitrochanterian resistance is almost nil, and therefore the positioning precision of rotor is high, very accurately.And the stator and rotor of encoder often relatively rotate one week, just the very little high level signal of a length can be exported, the relative position of the stator and rotor of encoder corresponding when using encoder zero-crossing testing-calibrating instrument this signal to be detected is the actual zero point of encoder, use the actual zero point of encoder, provide more accurate feedback signal can to its host controller.Installation site on motor body and erection sequence by adjustment brake and encoder, more traditional assembly technology, installation accuracy error improves about 10%.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of assembling with the AC servo motor of brake.
In figure: 1 stator winding, 2 encoders, 3 motor back covers, 4 brakes, 5 brake casings, 6 rotors.
Embodiment
Below, by reference to the accompanying drawings and most preferred embodiment, be further described.
As shown in Figure 1, installation site on motor body and erection sequence by adjustment brake and encoder, improve the positioning precision of zero point relative to motor rotor magnetic steel position of encoder.
(1) stator winding is press-fited in motor case; Press-fited by the fore bearing of rotor in the bearing chamber of front end housing, now, rotor is through stator winding; Mounted motor front end housing; Mounted motor rear end cap; First complete the installation of stator winding, rotor, front end housing, rear end cap;
(2) again stator winding is passed to 5V direct current, wherein the U of stator winding connects positive source, V, W connect power cathode, now the magnetomotive force that produces of stator winding and the magnetomotive force of rotor magnetic steel interact the synthesis magnetomotive force produced, rotor magnetic steel is locked in a certain fixed angle of radial circumference, determines the dead-center position of rotor magnetic steel; Do not assemble brake due on now rotor, now epitrochanterian resistance is almost nil, and therefore the positioning precision of rotor is high, very accurately;
(3) encoder zero-crossing detector is utilized to find the actual zero point of encoder; Use can provide more accurate feedback signal to its host controller the actual zero point of encoder;
(4) make the actual zero point of encoder consistent with the dead-center position of rotor magnetic steel, just find the encoder at zero point to be installed on the Rotor terminal of locked position; So the anglec of rotation of encoder and dead-center position just represent the anglec of rotation and the dead-center position of rotor magnetic steel;
(5) mounted motor back cover; Encoder is installed in motor back cover;
(6) brake passes to 24V direct current, opens band-type brake, is installed on by brake on front end housing, completes follow-up installation.
Above-mentioned a kind of AC servo motor assembly technology with brake is installation site on motor body and erection sequence by adjustment brake and encoder, and more traditional assembly technology, installation accuracy error improves 10%.Effectively improve the positioning precision of zero point relative to motor rotor magnetic steel position of encoder.
The foregoing is only better possible embodiments of the present invention, not thereby limit to the scope of the claims of the present invention, therefore the equivalence change that every utilization specification of the present invention and accompanying drawing content are done, be all contained in protection scope of the present invention.
