[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example

[0018] See also Figure 1-2 The utility model provides the following technical solutions: a rotating structure of a CNC end milling machine, comprising a servo motor 2, a rotating structure body 12 and a connecting base 6, a main shaft 7 is provided above the rear end of the rotating structure body 12, a torque detection device 11 is provided on one side of the main shaft 7, and a plug-in block hole 10 is provided in front of the servo motor 2.

[0019] In this embodiment, the torque detection device 11 measures the torsional deformation of the mechanical element under the action of torque and converts the torque into a measurable electrical signal. This electrical signal is usually proportional to the torque, thereby achieving accurate torque detection. Specifically, it is expressed as: the excitation magnetic field and the induced potential:

[0020] A torque sensor typically contains an excitation winding and an output winding, which are perpendicular to each other and rotate simultaneously with the sensor shaft. When AC current is applied to the excitation winding, a pulsating magnetic field is generated. The magnitude of this magnetic field varies over time. When the sensor shaft is subjected to load torque or torque, a torsion angle is generated. This causes the relative position of the excitation and output windings to shift, causing the excitation magnetic field to interlink with the output winding, generating an induced potential in the output winding.

[0021] Conversion of torsion angle and electrical signal:

[0022] The greater the torque applied to the sensor shaft, the greater the torsion angle generated, and thus the greater the induced potential in the output winding. Using the principle of magnetoelectric induction, the torsion angle is converted into a corresponding electrical signal output. This electrical signal is typically proportional to the torque and can therefore be used to indicate the magnitude of the torque.

[0023] The role of the digitizer:

[0024] To facilitate communication with a host PC and data processing, torque sensors are typically equipped with a digitizer. This digitizer converts the analog electrical signal corresponding to the torque angle into a corresponding digital output. This digital output allows the torque to be directly determined.

[0025] Specifically, a rotating shell 4 is provided in front of the plug-in block hole 10 . The rotating shells 4 are divided into three groups and distributed in a ring shape. Resistance-increasing grooves 3 are provided between the rotating shells 4 .

[0026] Specifically, a main shaft transmission device 1 is provided on the outer surface of the main shaft 7 .

[0027] Specifically, bolt holes 5 are provided on the outer surfaces of both sides of the connecting base 6 .

[0028] Specifically, a driver 8 is provided above the connecting base 6 .

[0029] Specifically, a pulling hole 9 is provided on the inner side surface of the driver 8 .

[0030] The working principle and usage process of the utility model are as follows: the rotating structure is placed in a fixed position on the milling machine, fixed with bolts at the bolt holes 5, and whether the installation needs to be clamped at the rotating shell 4 is selected whether to disassemble the rotating shell 4, and the bottom part of the component is installed at the resistance-increasing groove 3. Before that, the motor is started through the PLC and the rotating structure starts to work.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
