[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] See attached Figure 1-11 A sensor magnet base structure suitable for curved surface adsorption includes a magnet base 1, the main body of the magnet base 1 is a cylindrical structure, the adsorption surface of the magnet base includes two symmetrically arranged convex arc surfaces 2, a concave plane 4 is formed between the two convex arc surfaces 2, the concave plane 4 is a horizontal plane, and the concave plane 4 and the convex arc surfaces 2 on both sides are transitioned through an inclined plane 3. The two convex arc surfaces 2, the two inclined planes 3 and the concave plane 4 in the middle together constitute the upper end surface of the cylindrical structure of the magnet base 1, and the convex arc surfaces 2 and the inclined planes 3 on both sides of the concave plane 4 are symmetrical to each other; the center of the concave plane is provided with an M6 threaded through hole 5 for connecting the sensor. The side surface of the magnet base 1 is coated with an iron coating 6. The iron coating 6 forms a cylindrical structure, the upper surface of the iron coating 6 is flush with the concave plane 4, and the convex arc surfaces 2 and the inclined planes 3 on both sides of the concave plane 4 protrude from the upper surface of the iron coating 6. The outer surface of the iron coating 6 is provided with anti-slip vertical stripes 7.

[0029] Furthermore, the iron clad 6 is a cylindrical structure, the inner diameter of the iron clad is 30 mm, the thickness of the iron clad is 1.9 mm, and the axial height of the iron clad is 13 mm.

[0030] Furthermore, the main body of the magnet base 1 is a cylindrical structure, and the outer diameter of the magnet base is 30mm; the longitudinal section of the convex arc surface 2 is an arc, the radius of the arc is 3.45mm, the intersection of the convex arc surface 2 and the outer peripheral surface of the magnet base is a curve, the height of the lowest point of the curve is 14.67mm, the intersection of the convex arc surface 2 and the inclined surface 3 is a straight line, and the height difference between the straight line and the concave plane 4, that is, the height difference of the inclined surface 3 is 4.06mm; the inclination angle of the inclined surface 6 is 40°; the width of the concave plane 4 is 9mm, and the axial height of the concave plane 4 is 13mm. When the magnet base 1 adsorbs the outer curved surface, the convex arc surface 2 or the inclined surface 3 of the magnet base 1 is in line contact with the outer curved surface for magnetic attraction; when the magnet base 1 adsorbs the inner curved surface, the convex arc surface 2 of the magnet base 1 is in line contact with the inner curved surface for magnetic attraction.

[0031] Based on the above technical solution, it should be noted that the convex arc surface 2 is a convex cylindrical arc surface rather than a spherical curved surface. The cylindrical convex arc surface is in line contact with the curved surface or plane during adsorption, and the magnetic attraction state is relatively stable. The concave plane 4 in the middle and the inclined surfaces 3 on both sides play a V-shaped positioning role, forming an accommodation space for the magnetic attraction positioning outside the curved surface.

[0032] In this embodiment, the magnet base is designed as a combination of an outer convex arc surface and an inclined surface, so that the magnet base has at least two line contacts on the inner side of the curved surface, the outer side of the curved surface, and the plane, solving the problem of unstable magnetic attraction of the sensor on the concave surface of the curved surface. The function of the iron clad 6 is to prevent the magnet from breaking, while reducing the lateral magnetic force and reducing the influence of lateral attraction to equipment or other debris; the M6 ​​threaded through hole 5 is used to insert a screw to fix the sensor.

[0033] The magnet base of this embodiment has the following advantages: 1. When the magnet is concave in the plane, that is, when measuring on the inside of the curved surface, Fig.10 , which can achieve stable and firm magnetic attraction. 2. The magnet has a huge magnetic force, which makes the magnet and the workpiece surface have raised corners, which is convenient for removing the magnet by hand after the test is completed, which is more convenient and quick. 3. The arc erases most of the edges and corners of the magnet base itself, making the edge of the magnet not easy to break.
