Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

The invention provides a vibrating wire drilling stress meter mounting head.

As shown in Figure 1, Figure 2 and Figure 3, the mounting head has a cylindrical structure. Positioning slot 1 and positioning slot 2 are located on the side of the cylindrical mounting head. Positioning holes 3 and threaded holes 4 are located on the sides of the cylindrical mounting head respectively. Upper and lower bottom surfaces; the outer diameter of the mounting head is 32.5mm and the length is 150mm.

In the actual design process, the positioning groove 1 is a rectangular groove perpendicular to the bottom surface of the cylindrical mounting head with the positioning hole 3. The center line of the positioning groove 1 is 5mm from the center of the cylindrical mounting head. The width is 4mm and the depth is 30mm.

Positioning groove two 2 is a rectangular groove that runs through the side of the cylindrical mounting head and is perpendicular to the bottom surface of the cylindrical mounting head. Positioning groove two 2 is distributed along the axis of the mounting head. The center line of positioning groove two 2 is perpendicular to the center line of positioning groove one 1.

The width of the positioning slot 2 is 10mm and the length is 150mm. It is divided into three sections: front, middle and rear. The length of the front section is 30mm and is connected with the positioning hole 3. The length of the middle section is 70mm and the depth is 14.55mm.
