BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the flange neck detection tooling described in the present invention. DETAILED DESCRIPTION

[0011] The present invention is further described in detail below in conjunction with specific embodiments and drawings.

[0012] like Figure 1 As shown, a flange neck detection tooling comprises: a horizontal ruler 1, a vertical ruler 2, a first swing rod 3, a second swing rod 4, and a movable vertical ruler 5. The horizontal ruler 1 and the vertical ruler 2 are arranged in an L shape, the outer end of the horizontal ruler 1 and the top of the vertical ruler 2 are vertically fixed to each other, a scale is arranged on the lower edge of the horizontal ruler 1, and a scale is also arranged on the vertical edge inside the vertical ruler 2, and the zero point of the scale on the horizontal ruler 1 and the zero point of the scale on the vertical ruler 2 are both located at the intersection of the lower edge of the horizontal ruler 1 and the vertical edge inside the vertical ruler 2, and a guide long hole 11 arranged along the horizontal ruler 1 is also arranged on the horizontal ruler 1, the first swing rod 3, the second swing rod 4, The upper ends of the movable vertical ruler 5 are hinged to the horizontal ruler 1, so that the first swing rod 3, the second swing rod 4, and the movable vertical ruler 5 can swing inward and outward, and the hinge axes of the first swing rod 3, the second swing rod 4, and the movable vertical ruler 5 are all located in the guide long hole 11, so that the first swing rod 3, the second swing rod 4, and the movable vertical ruler 5 can also move inward and outward along the guide long hole 11, the second swing rod 4 is located on the inner side of the first swing rod 3, and the movable vertical ruler 5 is located on the inner side of the second swing rod 4. A scale is also set on the vertical edge of the outer side of the movable vertical ruler 5, and the zero point of the scale on the movable vertical ruler 5 is located at the intersection of the vertical edge of the outer side of the movable vertical ruler 5 and the lower edge of the horizontal ruler 1.

[0013] In this embodiment, a locking nut 6 is threadedly connected to the hinge shaft of the first swing arm 3, the second swing arm 4, and the movable vertical ruler 5, and the first swing arm 3, the second swing arm 4, and the movable vertical ruler 5 can be locked and fixed with the horizontal ruler 1 by screwing the locking nut 6 thereon. This arrangement is to lock the first swing arm 3, the second swing arm 4, and the movable vertical ruler 5 after they are adjusted to prevent them from moving and causing inaccurate detection.

[0014] In addition, a digital inclinometer 7 is provided on each of the first swing rod 3 and the second swing rod 4. The digital inclinometer 7 is a tool that can be purchased and used to detect the inclination. A positioning groove is provided on each of the first swing rod 3 and the second swing rod 4 for the digital inclinometer 7 to be inserted and positioned. Both digital inclinometers 7 are attached to the swing rods by magnets.

The inclination angles of the outer slope 82 and the inner slope 83 can be directly obtained by the digital inclinometer 7 on the first swing rod 3 and the second swing rod 4. In addition, the inclination angle of the outer slope 82 can also be obtained by substituting the scale reading on the horizontal ruler 1 aligned with the top of the outer slope 82 and the scale reading on the vertical ruler 2 aligned with the bottom of the outer slope 82 into the trigonometric function calculator. It can be calculated that the inclination angle of the inner slope 83 can also be calculated by subtracting the scale reading on the horizontal ruler 1 aligned with the top of the inner slope 83 from the scale reading on the horizontal ruler 1 aligned with the vertical edge of the outer side of the movable vertical ruler 5, and substituting the scale reading on the movable vertical ruler 5 aligned with the bottom of the inner slope 83 into the trigonometric function to calculate the width of the annular plane 81 is equal to the scale reading on the horizontal ruler 1 aligned with the top of the inner slope 83 minus the scale reading on the horizontal ruler 1 aligned with the top of the outer slope 82, and the thickness of the flange neck 8 is equal to the scale reading on the horizontal ruler 1 aligned with the vertical edge of the outer side of the movable vertical ruler 5.
