Description
Technical Field
The invention relates to the technical field of motors, in particular to a rotor winding device and a using method thereof.
Background
With the development of high-speed and ultra-high-speed motors, the linear speed of a rotor is usually 150m/s or higher, and the strength requirement on a rotor core is also higher and higher. Engineers often reduce the width of the magnetic bridge on the rotor core in order to improve the electromagnetic performance and achieve the purpose of high rotation speed, resulting in sacrificing the strength of the rotor core. In this regard, in the prior art, the strength of the rotor core is enhanced by winding carbon fibers on the outer surface of the rotor core, when the carbon fibers are wound on the rotor core, certain tensile force needs to be applied to the carbon fibers by winding equipment, so that certain pre-compression force can exist on the rotor by the carbon fibers after the rotor is wound, and if the pre-compression force is too large after the carbon fibers are wound on the rotor, the risk of yielding damage occurs when the rotor core is compressed in a static state; if the pre-pressure is too small, the rotor core is in tension to generate the risk of yielding or even breaking under the high-speed rotation state, but the pre-pressure of the core can not be detected after the carbon fiber is wound, and the rotor core structure of the built-in magnetic steel is complex, and even if the cores with the same outer diameter are used, the pre-pressure can be greatly different. Therefore, in the prior art, the relation between the precompression of the carbon fiber on the rotor and the tensile force applied to the carbon fiber by the winding equipment is often calculated according to the mechanical model of the winding carbon fiber, and then the precompression of the carbon fiber on the rotor core is controlled by controlling the tensile force of the winding equipment on the carbon fiber. However, the mode only controls the tension output by the winding equipment, and the pressure inside the carbon fiber in the production process cannot be obtained, so that the tension output by the winding equipment cannot be adjusted in real time in the production process, and finally the risk that the precompression of the carbon fiber on the rotor core is still high or low is still caused.

The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
As shown in fig. 1, the invention provides a rotor winding device, which comprises a first motor 1, a second motor 3 and a calibration cylinder 5, wherein an output shaft of the first motor 1 is fixedly connected with a supply cylinder 2, carbon fibers 8 are wound on the outer side of the supply cylinder 2, a test cylinder 4 or a rotor is detachably connected to an output shaft of the second motor 3, the second motor 3 is used for driving the test cylinder 4 or the rotor to rotate, the calibration cylinder 5 is arranged between the first motor 1 and the second motor 3, the calibration cylinder 5 and the supply cylinder 2 are arranged in parallel, an output shaft of the second motor 3 and the test cylinder 4 or the rotor are coaxially arranged, and the test cylinder 4 or the rotor can reciprocate along an axis. The calibration cylinder 5 and the test cylinder 4 or the rotor are arranged in parallel, specifically, when the test cylinder 4 is detachably connected to the output shaft of the second motor 3, the supply cylinder 2, the calibration cylinder 5 and the test cylinder 4 are parallel to each other; when the rotor is detachably connected to the output shaft of the second motor 3, the supply cylinder 2, the calibration cylinder 5 and the rotor are parallel to each other. The carbon fiber 8 winds around the calibration cylinder 5, the carbon fiber 8 winds around the outer side of the testing cylinder 4 or the rotor, the first motor 1 is used for applying tension to the carbon fiber 8, and the first motor 1 changes the tension applied to the carbon fiber 8 by changing the output torque of the first motor, so that the tension of the carbon fiber 8 is changed. It will be appreciated that the tension of the carbon fibre 8 itself after acting on the calibration cylinder 5 is reflected in the pressure of the carbon fibre 8 against the calibration cylinder 5. The calibration cylinder 5 is thus used to detect the pressure of the carbon fibres 8 against the calibration cylinder 5. Through setting up the calibration section of thick bamboo 5 between first motor 1 and second motor 3, can detect the pressure of carbon fiber 8 to the calibration section of thick bamboo 5 in the production process to can be according to the moment of torsion of the output of testing result adjustment first motor 1, make final carbon fiber 8 to the precompression of rotor be in reasonable within range. The first motor 1 may be a servo motor or a stepper motor, in this embodiment the first motor 1 is preferably a servo motor. The second motor 3 may be a servo motor or a stepper motor, in this embodiment the second motor 3 is preferably a servo motor.
In this embodiment, the carbon fibers 8 include carbon fiber cloth and carbon fiber filaments, and the carbon fiber cloth is a braid composed of carbon fiber filaments. The carbon fiber cloth or the carbon fiber yarn can be selected by those skilled in the art according to actual demands, and the winding device in this embodiment may be used for the winding process, and is not specifically limited herein.
Specifically, a plurality of strain gauges 9 are uniformly adhered to the outer side of the calibration cylinder 5 along the circumferential direction, and the strain gauges 9 can detect the pressure of the carbon fibers 8 on the calibration cylinder 5. The strain gauge 9 may be adhered in a direction parallel to the radial direction of the calibration cylinder 5, may be adhered in a direction parallel to the axial direction of the calibration cylinder 5, or may be adhered at an angle of 45 ° to the radial direction or the axial direction of the calibration cylinder 5, and the specific adhering manner is not limited herein. During the winding of the carbon fiber 8, the second motor 3 rotates to start winding of the carbon fiber 8, during which the tension of the carbon fiber 8 is changed by controlling the torque output from the first motor 1 to be changed, and can be applied to the rotor in the form of pressure. Because the calibration cylinder 5 is arranged between the first motor 1 and the second motor 3, and the carbon fiber 8 winds the calibration cylinder 5, the carbon fiber 8 can press the strain gauge 9 stuck on the calibration cylinder 5, under the piezoelectric effect, the strain gauge 9 can output an electric signal outwards, and the electric signal can be converted into a pressure value through a related electric signal processing device in the prior art, so that whether the torque output by the first motor 1 meets the process requirement or not is judged, and related adjustment is further carried out. The tension force of the carbon fiber 8 acts on the test cylinder 4 or the calibration cylinder 5, which is represented by the pressure of the carbon fiber 8 on the test cylinder 4 or the calibration cylinder 5, so that whether the torque output by the first motor 1 meets the process requirement can be judged by testing the pressure of the carbon fiber 8 acting on the test cylinder 4 or the calibration cylinder 5.
Further, the rotor winding device further includes a first adjusting member and a second adjusting member. The first adjustment member comprises a first tensioning wheel 6, a first adjustment motor (not shown in the figures) and a first eccentric (not shown in the figures). The first adjusting motor is fixedly connected with one end of the first eccentric wheel, and the first adjusting motor can drive the first eccentric wheel to rotate. The first adjustment motor may be a servo motor or a stepper motor and the first eccentric is preferably a cam. The other end of the first eccentric wheel is connected with a first tensioning wheel 6, an axle is fixedly arranged at the other end of the first eccentric wheel, and the first tensioning wheel 6 is rotatably sleeved on the axle, so that the first tensioning wheel 6 can move along the preset direction when the first adjusting motor drives the eccentric wheel to rotate. The first tensioning wheel 6 is arranged between the first motor 1 and the calibration cylinder 5, in particular the first tensioning wheel 6 is arranged between the supply cylinder 2 and the calibration cylinder 5. The carbon fiber 8 is wound on the outer side of the first tensioning wheel 6. The first tensioning wheel 6 is movable in a direction perpendicular to the common tangent of the supply cylinder 2 and the calibration cylinder 5. Since the arrangement of the carbon fibers 8 may be varied, for example, the carbon fibers 8 may be arranged along the inner common tangent of the supply cylinder 2 and the calibration cylinder 5, or may be arranged along the outer common tangent of the supply cylinder 2 and the calibration cylinder 5. So when the carbon fiber 8 is arranged along the internal common tangent of the supply cylinder 2 and the calibration cylinder 5, the first tensioning wheel 6 can move along the internal common tangent perpendicular to the supply cylinder 2 and the calibration cylinder 5, thereby changing the wrap angle between the carbon fiber 8 and the calibration cylinder 5, and further changing the contact angle between the carbon fiber 8 and the calibration cylinder 5 and the pressure to the calibration cylinder 5. When the carbon fiber 8 is arranged along the outer common tangent of the supply cylinder 2 and the calibration cylinder 5, the first tensioning wheel 6 can move along the outer common tangent perpendicular to the supply cylinder 2 and the calibration cylinder 5, so that the wrap angle between the carbon fiber 8 and the calibration cylinder 5 is changed, and the contact angle between the carbon fiber 8 and the calibration cylinder 5 and the pressure on the calibration cylinder 5 are further changed. In the present embodiment, the carbon fibers 8 are preferably arranged along the outer common tangent of the supply cylinder 2 and the calibration cylinder 5, and the corresponding first tensioning wheel 6 is movable along the outer common tangent perpendicular to the supply cylinder 2 and the calibration cylinder 5.
Still further, the second adjusting member comprises a second tensioning wheel 7, a second adjusting motor (not shown in the figures) and a second eccentric (not shown in the figures). The second adjusting motor is fixedly connected with one end of the second eccentric wheel, and the second adjusting motor can drive the second eccentric wheel to rotate. The second adjustment motor may be a servo motor or a stepper motor and the second eccentric is preferably a cam. The other end of the second eccentric wheel is connected with a second tensioning wheel 7, an axle is fixedly arranged at the other end of the second eccentric wheel, and the second tensioning wheel 7 is rotatably sleeved on the axle, so that the second tensioning wheel 7 can move along the preset direction when the second adjusting motor drives the eccentric wheel to rotate. The second tensioning wheel 7 is arranged between the calibration cylinder 5 and the second motor 3, specifically, when the output shaft of the second motor 3 is detachably connected with the test cylinder 4, the second tensioning wheel 7 is arranged between the calibration cylinder 5 and the test cylinder 4; when the output shaft of the second motor 3 is detachably connected to the rotor, the second tensioning wheel 7 is arranged between the calibration cylinder 5 and the rotor. For convenience of explanation, the following description will be given by taking an example in which the output shaft of the second motor 3 is detachably connected to the test cartridge 4, which is completely identical to the case in which the output shaft of the second motor 3 is detachably connected to the rotor. The carbon fiber 8 is wound on the outer side of the second tensioning wheel 7. The second tensioning wheel 7 is movable in a direction perpendicular to the common tangent of the calibration cylinder 5 and the test cylinder 4. The carbon fibers 8 may be arranged in various ways, for example, the carbon fibers 8 may be arranged along an inner common tangent line of the calibration cylinder 5 and the test cylinder 4, or may be arranged along an outer common tangent line of the calibration cylinder 5 and the test cylinder 4. So when carbon fiber 8 sets up along the interior public tangent line of demarcation section of thick bamboo 5 and test section of thick bamboo 4, second take-up pulley 7 can be along perpendicular to the interior public tangent line of demarcation section of thick bamboo 5 and test section of thick bamboo 4 to change the wrap angle between carbon fiber 8 and the demarcation section of thick bamboo 5, and then change carbon fiber 8 and the contact angle of demarcation section of thick bamboo 5 and to the pressure of demarcation section of thick bamboo 5. When the carbon fiber 8 is arranged along the outer common tangent of the calibration cylinder 5 and the test cylinder 4, the second tensioning wheel 7 can move along the outer common tangent perpendicular to the calibration cylinder 5 and the test cylinder 4, so that the wrap angle between the carbon fiber 8 and the calibration cylinder 5 is changed, and the contact angle between the carbon fiber 8 and the calibration cylinder 5 and the pressure on the calibration cylinder 5 are further changed. In this embodiment, the carbon fibers 8 are preferably arranged along the outer common tangent of the calibration cylinder 5 and the test cylinder 4, and the corresponding second tensioning wheel 7 is movable along the outer common tangent perpendicular to the calibration cylinder 5 and the test cylinder 4.
Specifically, in the present embodiment, by providing the carbon fibers 8 along the outer common tangents of the supply cylinder 2 and the calibration cylinder 5 and along the outer common tangents of the calibration cylinder 5 and the test cylinder 4, the corresponding first tension wheel 6 can be moved along the outer common tangents perpendicular to the supply cylinder 2 and the calibration cylinder 5 and the second tension wheel 7 can be moved along the outer common tangents perpendicular to the calibration cylinder 5 and the test cylinder 4. The first tensioning wheel 6 and the second tensioning wheel 7 act together to enable the pressure distribution of the carbon fibers applied to the calibration cylinder 5 to be more uniform, so that the pressure value of the carbon fibers 8 on the test cylinder 4 is more stable, and the pressure distribution of the wound carbon fibers 8 is ensured to be more uniform.
Specifically, the rotor winding device is in a calibrated state when the test cartridge 4 is connected to the output shaft of the second motor 3. When the rotor is connected to the output shaft of the second motor 3, the rotor winding device is in a production state. The outer diameter of the test cylinder 4 is equal to the outer diameter of the rotor. The rotor winding device for ensuring the calibration of the outer wall can be suitable for the production of the rotor.
The invention also provides a using method of the rotor winding device, which is applied to the rotor winding device in the embodiment. Firstly, the testing cylinder 4 is connected with an output shaft of the second motor 3, and the rotor winding device is calibrated and a calibration result is obtained. The test cartridge 4 is then removed and the rotor is connected to the output shaft of the second motor 3. Finally, winding carbon fiber 8 around the rotor according to the calibration result.
Specifically, during calibration of the rotor winding apparatus, the test cylinder 4 is able to detect the pressure of the carbon fiber 8 wound on the test cylinder 4. The testing cylinder 4 is coaxially arranged with the output shaft of the second motor 3, and a plurality of strain gauges 9 are uniformly attached to the outer side of the testing cylinder 4 along the circumferential direction, so that the pressure of the carbon fiber 8 on the testing cylinder 4 is detected, and the pressure values of the calibration cylinder 5 and the testing cylinder 4 are recorded by adjusting the output torque of the motor 1 and the positions of the tensioning wheel 6 and the tensioning wheel 7. The pressure of the carbon fibers 8 against the test cylinder 4 is made to satisfy a first preset value. The test cylinder 4 can also reciprocate along the axial direction while rotating, and the motion can be realized by arranging a linear electromagnetic valve in the prior art or adopting a multi-motor cooperation mode, and details are not repeated here.
Along with the operation of the test cylinder 4, the carbon fiber 8 wraps the outside of the test cylinder 4, and at this time, the winding of the first layer of carbon fiber 8 is completed, and in the winding process of the first layer of carbon fiber 8, the calibration result that can be obtained includes: the relation of the torque output by the first motor 1 and the rotation speed output by the second motor 3 and the position of the first tensioning wheel 6 and the second tensioning wheel 7 respectively, the relation of the pressure value output by the strain gauge 9 on the calibration cylinder 5 and the relation of the pressure value output by the strain gauge 9 on the test cylinder 4 respectively.
Winding of the second layer of carbon fibers 8 is continued. It will be appreciated that after the first layer of carbon fibers 8 is wound around the outside of the test tube 4, the positional relationship between the carbon fibers 8 and the test tube 4 changes when the second layer of carbon fibers 8 is wound, and thus the pressure of the carbon fibers 8 against the same changes. Therefore, after the first layer of carbon fiber 8 is wound, a plurality of strain gauges 9 are continuously attached along the circumferential direction to test the pressure value in the winding process of the second layer of carbon fiber 8, the torque output by the first motor and/or the rotating speed output by the second motor are changed according to the test result, and the positions of the first tensioning wheel 6 and/or the second tensioning wheel 7 are adjusted according to the requirement, so that the pressure of the carbon fiber 8 detected by the strain gauges 9 on the test cylinder 4 meets a second preset value, preferably the first preset value and the second preset value are equal, namely the pressure of the carbon fiber 8 on each layer on the test cylinder 4 is equal. In the process of winding each layer of carbon fiber 8, the calibration results obtained when winding the layer of carbon fiber can include: the relation of the torque output by the first motor 1 and the rotation speed output by the second motor 3 and the position of the first tensioning wheel 6 and the second tensioning wheel 7 respectively, the relation of the pressure value output by the strain gauge 9 on the calibration cylinder 5 and the relation of the pressure value output by the strain gauge 9 on the test cylinder 4 respectively. The above steps are repeated in a cyclic manner until the carbon fibers 8 are wound to the desired number of layers.
It will be appreciated that the calibration results obtained during the winding of the first layer of carbon fibres 8 and the calibration results obtained during the winding of each subsequent layer of carbon fibres 8 should be continuous in time, since the actual production process is continuous. I.e. the end point of the previous layer is at the same time as the start point of the next layer.
Specifically, during winding of the carbon fiber 8 around the rotor. According to the calibration result, when winding the carbon fibers 8 of different layers, production is performed according to the obtained calibration result. And adjusting the positions of the first tensioning wheel 6 and the second tensioning wheel 7 according to the calibration results of the first tensioning wheel 6 and the second tensioning wheel 7, simultaneously comparing the actual pressure value output by the strain gauge 9 on the calibration cylinder 5 with the calibration value at the moment, and if the pressure value output by the strain gauge 9 on the calibration cylinder 5 is consistent with the calibration results within the error allowable range, continuing winding the carbon fiber 8 on the rotor until the production is completed. If the pressure value output by the strain gauge 9 on the calibration cylinder 5 deviates greatly from the calibration result, the abnormal operation condition of the rotor winding device is indicated. The torque output by the first motor 1 and/or the rotational speed output by the second motor 3 can be adjusted to return the pressure value output by the strain gauge 9 on the calibration cylinder 5 to the normal interval. Namely, in the actual production process, the calibration cylinder 5 plays a role in anomaly monitoring, and the yield of products is further ensured.
