[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; DETAILED DESCRIPTION

[0016] Example 1

[0017] refer to Figure 1 and Figure 2 The embodiment of the utility model proposes a simple device for measuring the deformation of thin-walled parts, which is used to detect the deformation degree and deformation position of the inner hole of an annular thin-walled part 1, including: a base 2 and two positioning blocks 3; the surface of the base 2 is provided with reserved mounting holes 4 in pairs; the two positioning blocks 3 are respectively assembled in the two reserved mounting holes 4 through two positioning bolts 6.

[0018] When in use, the annular thin-walled part 1 is attached to the base 2, and the inner wall of the annular thin-walled part 1 is attached to the two positioning blocks 3 at the same time, and then the dial indicator 5 is fixed on the base 2, so that the measuring head of the dial indicator 5 is on the annular thin-walled part 1, and the pressed deflection value must be greater than the empirical deformation of the annular thin-walled part 1. The change in the deflection value of the dial indicator 5 is observed by rotating the annular thin-walled part 1, and the position of the maximum value and the position of the minimum value measured on the annular thin-walled part 1 are recorded, and then a clamping force is applied to the position of the maximum diameter value of the annular thin-walled part 1 to calibrate the circle.

[0019] Example 2

[0020] refer to Figure 1Based on Example 1, the angle between the axis of the two reserved mounting holes 4 where the two positioning blocks 3 are located and the axis of the annular thin-walled member 1 is greater than or equal to 90 degrees and less than or equal to 160 degrees.

[0021] When measuring the inner hole deformation of the annular thin-walled part 1, the two positioning blocks 3 are used to support the rotating annular thin-walled part 1. The greater the distance between the two positioning blocks 3, the more stable the support of the two positioning blocks 3 to the annular thin-walled part 1, and the higher the detection accuracy; the closer the distance between the two positioning blocks 3, the more unstable the support of the two positioning blocks 3 to the annular thin-walled part 1, and the lower the detection accuracy. Therefore, it is necessary to simultaneously ensure the stability of the support of the two positioning blocks 3 to the annular thin-walled part 1 and the accuracy of the probe detection of the dial indicator 5.

[0022] Example 3

[0023] refer to Figure 1 On the basis of Example 2, the perpendicular midline of the center line connecting the two reserved mounting holes 4 where the two positioning blocks 3 are located passes through the axis of the annular thin-walled part 1.

[0024] The measuring head of the dial indicator 5 should be located on the perpendicular midline of the line connecting the two reserved mounting holes 4. When using the measuring head of the dial indicator 5 to detect the deformation of the annular thin-walled part 1, the measuring direction of the measuring head should be along the direction of the indication line away from the two reserved mounting holes 4 and connected with the inner wall of the annular thin-walled part 1, so that the maximum deformation degree and deformation position of the annular thin-walled part 1 can be detected.

[0025] Example 4

[0026] refer to Figure 2 On the basis of Example 1, a plurality of pairs of reserved mounting holes 4 are arranged symmetrically on the base 2, and the distance between each pair of reserved mounting holes 4 gradually changes.

[0027] Each pair of reserved mounting holes 4 corresponds to a diameter of an annular thin-walled part 1 , and the stability of the support of the annular thin-walled part 1 by the positioning blocks 3 in each pair of reserved mounting holes and the accuracy of the probe detection of the dial indicator 5 need to be ensured at the same time.

[0028] Example 5

[0029] refer to Figure 1 and Figure 2 On the basis of Example 1, the two positioning blocks 3 are cylindrical structures and are respectively mounted on the two positioning bolts 6.

[0030] The cylindrical positioning block 3 matches the diameter of the positioning bolt 6 , and the positioning bolt 6 is screwed into the reserved mounting hole 4 to press and fix the positioning block 3 on the base 2 .

[0031] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by a technician familiar with the technical field within the technical scope of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims. The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry, and are not described here one by one.
