DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the adsorption diagram in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the adsorption diagram here can be arranged and designed in various different configurations.

[0037] In the following, some embodiments of the present application are described in detail in conjunction with the adsorption diagram. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0038] Please refer to Figures 1 to 4 As shown, an embodiment of the utility model provides an ultra-high power servo motor, which is applied to a laser galvanometer assembly, and includes: a stator body 101, in which a magnetic core rotor 102 is arranged, a first rotating shaft assembly is arranged at the head end thereof, and a second rotating shaft assembly is arranged at the tail end thereof; the first rotating shaft assembly is provided with a first output shaft 142 connected to the magnetic core rotor 102, and a first mounting hole 143 for mounting the galvanometer is radially arranged in the center of the first output shaft 142; the second rotating shaft assembly is provided with a driving circuit assembly 108, and the driving circuit assembly 108 is electrically connected to the stator body 101 and the sensor 181; a plurality of air holes 111 are arranged on the side of the stator body 101. By providing a plurality of air holes 111 on the side of the stator body 101, when the rotor therein is running, the airflow outside and inside the stator can be exchanged through the air holes 111, thereby effectively solving the problem of internal overheating; in addition, it also solves the problem that when the servo motor power is insufficient and when it is applied to the galvanometer, the galvanometer is easily damaged due to the large power of the laser and the high temperature during its operation. By providing a first mounting hole 143 for mounting the galvanometer in the radial direction of the center of the first output shaft 142, the galvanometer can be easily disassembled and assembled, and can be installed by plug-in, which is convenient and efficient.

[0039] Next, an ultra-high power servo motor in this exemplary embodiment will be further described.

[0040] In the embodiments of this application, refer to Figures 3 to 5 As shown, it also includes a flange 109; the flange 109 is provided with an extension tube, the flange 109 is connected to the head end of the stator body 101, the first output shaft 142 passes through the middle of the flange 109, and the extension tube is sleeved on the outside of the head end; through the above-mentioned flange 109, it is connected to the above-mentioned stator body, so that the above-mentioned ultra-high power servo motor can be conveniently installed in the target through the above-mentioned flange 109.

[0041] In the embodiment of the present application, as shown in reference 2, the first rotating shaft assembly includes a large bearing 103 and a first rotating shaft 104 sleeved on the center of the large bearing 103; the large bearing 103 is connected to the head end of the stator body 101, wherein the large bearing 103 can be embedded and sleeved on the head end of the stator body 101; the first rotating shaft 104, its first end is connected to the first end of the magnetic core rotor 102, and its second end is the first output shaft 142, which is used for the power output of the ultra-high power servo motor; the second rotating shaft assembly includes a bearing sleeve 107, a small bearing 105 and a second rotating shaft 106; the bearing sleeve 107 is connected to the tail end of the stator body 101; the small bearing 105 is sleeved on the shaft The center of the sleeve 107; the first end of the second rotating shaft 106 is sleeved in the small bearing 105, and the second end is connected to the second end of the magnetic core rotor 102. The large bearing 103 at the head end and the small bearing 105 at the tail end make the rotor rotate with less friction, so that the bearing accuracy can be maintained; the outside of the bearing sleeve 107 is connected with the drive circuit component 108. The drive circuit component 108 is arranged on the outside of the above-mentioned bearing sleeve 107, and the drive circuit component 108 is electrically connected to the stator body 101. The coil is not shown in the figure. Through the coil, the motor is connected without a brush, and there is no need to change the current direction through a brush. The drive circuit is controlled, thereby increasing the service life.

[0042] In the embodiment of the present application, both ends of the magnetic core rotor 102 are provided with cylindrical connectors 121 with a diameter smaller than that of the magnetic core rotor 102; the first rotating shaft 104 and the second rotating shaft 106 are respectively provided with a first sleeve cavity 141 and a second sleeve cavity 161 for connecting the cylindrical connector 121; the outer diameters of the first sleeve cavity 141 and the second sleeve cavity 161 are the same as those of the magnetic core rotor 102; Figure 2 and Figure 4As shown, by arranging cylindrical connectors 121 having a diameter smaller than that of the core rotor 102 at both ends of the core rotor 102, the first sleeve cavity 141 and the second sleeve cavity 161 can be sleeved on the cylindrical connector 121, and the outer diameters of the first sleeve cavity 141 and the second sleeve cavity 161 can be smaller than or equal to the diameter of the core rotor 102, so that the first rotating shaft 104 and the second rotating shaft 106 can be connected to the core rotor 102, while reducing the space occupied by the connection.

[0043] In the embodiment of the present application, the driving circuit assembly 108 is arranged at the central position of the outer side of the bearing sleeve 107; a terminal cap 183 is also arranged in the middle of the driving circuit assembly 108, and an indicator light 182 is arranged on the terminal cap 183, and the indicator light 182 is electrically connected to the driving circuit assembly 108. The indicator light 182 can be used to indicate the working state of the motor, and in conjunction with the sensor 181, it can be used to detect the running state of the rotor, whether it is rotating, for example, when it is rotating, the indicator light 182 is on, when it is not rotating, the indicator light 182 is off, or when the driving circuit has a driving output, the light is on, and the indicator light 182 can also use a color LED to indicate different states through different colors.

[0044] It should be noted that the implementation of the driving circuit of the specific indicator light 182 (LED light) is a conventional technical means in this field and will not be described in detail here.

[0045] In the embodiments of this application, refer to Figure 5 and Figure 6 As shown, a limiting groove 191 is further provided inside the flange 109; a limiting hole 144 for installing a limiting member is provided on the first output shaft 142. The limiting groove 191 cooperates with the limiting rod provided in the limiting hole to limit the maximum rotation angle of the limiting position to 5°-30°, wherein the preferred maximum rotation angle of the limiting position in the present application is 18°, and when used to connect the galvanometer assembly and used as a laser assembly, the laser scanning can be limited to a suitable range.

[0046] A limit rod (not shown in the figure) can be set in the above-mentioned limit hole 144, and the outside of the limit rod is located in its limit groove 191 to form a physical limit to prevent the soft limit from failing and the motor from continuing to run, causing damage to the components installed on the first output shaft 142. Especially when used for installing a galvanometer, since it is a vulnerable part, it is very easy to be damaged when encountering a collision. The physical limit can avoid greater problems with the equipment due to soft limit failure.

[0047] In addition, the connection between the first sleeve cavity 141 and the second sleeve cavity 161 and the cylindrical connector 121 can also be set to a magnetic type, which can avoid the problem of the motor rotor being stuck due to physical limit. For example, when the soft limit fails or is misoperated, although the physical limit can ensure that the first output shaft 142 will not continue to rotate, the motor is still in a driven state. Through the magnetically connected first sleeve cavity 141 and the second sleeve cavity 161, when the magnetic core rotor 102 outputs a large torque to the cylindrical connector 121, the magnetic core rotor 102 is prevented from being locked, thereby burning the coil inside the motor.

Therefore, the attached claims are intended to be interpreted as including optional embodiments and all changes and modifications that fall within the scope of the utility model embodiments.
