[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a horizontal sensor fixing structure includes an integrated sensor bracket 1, and a sensor 2 is connected to a vertical core shaft 3 through the integrated sensor bracket 1. The vertical core shaft 3 is provided with an inner hole matching the D-shaped axis of the sensor 2, and the vertical core shaft 3 is connected to a rotating body 4.

[0019] The integrated sensor bracket 1 comprises a U-shaped bracket, which comprises a transverse mounting plate 11 and vertical support rods 12 located on both sides of the transverse mounting plate 11, and a wing plate 13 is connected to the end of each vertical support rod 12, and the wing plate 13 is arranged parallel to the transverse mounting plate 11. The transverse mounting plate 11 is provided with a D-shaped hole 14 and a sensor fixing hole 15, wherein the D-shaped hole 14 is located at the geometric center of the transverse mounting plate 11, and the sensor fixing holes 15 are distributed on a circumference centered on the D-shaped hole 14. Each wing plate 13 is provided with at least one waist hole 16, and the waist hole 16 is connected to the entire integrated sensor bracket 1 to the large bracket 5 by fixing bolts.

[0020] Furthermore, the D-shaped hole 14 is φ6, and the φ6 D-shaped hole is used to limit the D-shaped axis of the sensor to ensure that the direction of the plane (the reference plane for collecting signals) meets the design requirements.

[0021] Furthermore, there are 4 sensor fixing holes 15 in total, which ensures that the orientation of the sensor harness socket meets the use requirements under different installation situations.

[0022] Furthermore, the length of the waist hole 16 is set to an adjustment range of 8 mm, which is used to adjust the relative position of the sensor axis and the vertical core shaft 3 during installation to ensure their coaxiality.

[0023] The working process of the utility model is as follows:

[0024] 1. Adjust the plane section of the D-shaped axis of the sensor 2 until it can be inserted into the D-shaped hole 14 of the integrated sensor bracket 1;

[0025] 2. Align the two mounting holes of sensor 2 with the mounting holes of the integrated sensor bracket, and insert the M4 bolts for pre-tightening;

[0026] 3. Insert the D-shaped shaft of sensor 2 into the inner hole of vertical mandrel 3, making sure that the sensor harness connector faces outward;

[0027] 4. Align the waist hole 16 on the integrated sensor bracket 1 with the positioning hole on the large bracket 5, and observe whether the sensor 2 is in a straight line with the vertical core shaft 3 after installation; insert 4 M10 bolts, pre-tighten, and continue to adjust the coaxiality of the sensor and the vertical core shaft 3 after installation until the two are in a straight line. Tighten the M10 bolts diagonally and recheck the coaxiality;

[0028] 5. Push and pull the sensor 3 to 4 times to confirm that the D-shaped shaft runs smoothly and without obstruction in the vertical core shaft 3.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
