[0025] The technical solution of the present invention will be further explained below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments described below.

[0026] Reference Figure 1 In the present invention, the annular structure workpiece 4 is composed of three arc structures, wherein the circumference of the annular structure workpiece 4 is recorded as d, and the arc lengths corresponding to the three arc structures are 1 / 2d, 1 / 4d, and 1 / 4d respectively.

[0027] Reference Figures 1 to 3A tool for roundness detection of an annular workpiece includes a mounting base 1, a fixing assembly 2, and a roundness detection assembly 3. The mounting base 1 is connected to the annular workpiece 4 via the fixing assembly 2; the fixing assembly 2 includes a plurality of fixing members 21 distributed along the circumference of the annular workpiece 4. The roundness detection assembly 3 is connected to the mounting base 1 and is used to perform roundness detection on the annular workpiece 4.

[0028] In the present invention, the fixing members 21 can be set to six, seven, or eight. An appropriate number of fixing members 21 can be set to achieve a stable connection between the annular structure workpiece 4 and the mounting base 1 through the fixing members 21. Such setting methods are all acceptable.

[0029] Reference Figure 1 and Figure 3 The fixing member 21 includes a first connecting portion 211 and a second connecting portion 212. The first connecting portion 211 is connected to the second connecting portion 212; the first connecting portion 211 is connected to the annular structure workpiece 4, and the second connecting portion 212 is connected to the mounting base 1.

[0030] In the present invention, the fixing member 21 can be a Z-shaped clamp, an adjustable clamp, a bolt clamp, etc., and any setting method that stably connects the annular structure workpiece 4 and the mounting base 1 through the fixing member 21 is acceptable.

[0031] Reference Figure 1 and Figure 3 The mounting base 1 includes a supporting portion 11 and a mounting portion 12 . The mounting portion 12 is mounted on the supporting portion 11 ; the mounting portion 12 is connected to the annular structure workpiece 4 through a plurality of fixing members 21 .

[0032] In the present invention, the cross-sections of the supporting portion 11 and the mounting portion 12 can be rectangular, square, polygonal, etc.

[0033] Reference Figure 1 and Figure 2 The roundness detection assembly 3 includes a support rod 32 and a roundness detection rod 31. The support rod 32 is connected to the mounting base 1; the roundness detection rod 31 is movably connected to the end of the support rod 32 away from the support portion 11, and the roundness detection rod 31 can rotate around the axis of the support rod 32, and the axial direction of the roundness detection rod 31 is perpendicular to the axial direction of the support rod 32; the end of the roundness detection rod 31 away from the support rod 32 extends toward the inner surface of the annular structure workpiece 4, and when there is no gap between the roundness detection rod 31 and the inner surface of the annular structure workpiece 4, the roundness of the annular structure workpiece 4 meets the requirements.

[0034] Specifically, an installation groove is provided at one end of the support rod 32 away from the support part 11, and a sliding sleeve is connected to the installation groove. The sliding sleeve is sleeved on the support rod 32, and the sliding sleeve is engaged in the installation groove. The roundness detection rod 31 is fixedly connected to the sliding sleeve, and the sliding sleeve drives the roundness detection rod 31 to rotate synchronously around the axis of the support rod 32.

[0035] In the present invention, when performing roundness detection of the annular structure workpiece 4, first, the end of the roundness detection rod 31 is adjusted to be in direct contact with the inner surface of the annular structure workpiece 4; then, the roundness detection rod 31 is driven to rotate around the axis of the supporting vertical rod 32 for one circle. During this process, the end of the roundness detection rod 31 will slide along the inner surface of the annular structure workpiece 4; if during the entire rotation process, the end of the roundness detection rod 31 and the inner surface of the annular structure workpiece 4 always maintain a state of no gap, it can be judged that the roundness of the annular structure workpiece 4 meets the requirements. If during the entire rotation process, the gap between the roundness detection rod 31 and the inner surface of the annular structure workpiece 4 changes, that is, sometimes they are in contact and sometimes they are separated, it indicates that there is a deviation in the roundness of the annular structure workpiece 4, which does not meet the roundness requirements and requires further analysis or adjustment.

[0036] Example 1:

[0037] Reference Figure 1 and Figure 3 In this embodiment, a tool for detecting the roundness of an annular structure workpiece is provided, and the number of the fixing members 21 is seven.

[0038] Specifically, three fixing members 21 are installed on the arc structure with an arc length of 1 / 2d, and two fixing members 21 are installed on each of the two arc structures with an arc length of 1 / 2d.

[0039] In this embodiment, a fixing part 21 is added to the longer arc structure so that seven fixing parts 21 are evenly distributed on the entire annular structure workpiece 4. During the roundness detection process, the shaking of the annular structure workpiece 4 due to external force or its own gravity is reduced, thereby ensuring the accuracy and stability of the roundness detection.

[0040] Example 2:

[0041] Reference Figure 1 and Figure 3 This embodiment is a tool for detecting the roundness of an annular structure workpiece. Based on the embodiment 1, the fixing member 21 is a Z-shaped clamping block.

[0042] In this embodiment, the fixing member 21 is configured as a Z-shaped clamping block, which is convenient for installation and disassembly, thereby improving work efficiency.

[0043] Example 3:

[0044] Reference Figure 1 and Figure 2 This embodiment of the roundness detection tooling for annular workpieces includes a roundness detection assembly 3, which also includes an adjustment sleeve 33 and a locking member. One end of the adjustment sleeve 33 is connected to the mounting base 1, and the support rod 32 is nested within the adjustment sleeve 33. The locking member passes through the adjustment sleeve 33 and connects to the support rod 32, securing the support rod 32 within the adjustment sleeve 33.

[0045] Specifically, the locking member can be a combination of a bolt and a nut, that is, a plurality of threaded holes are provided in the axial direction on the adjusting sleeve 33, a corresponding plurality of threaded holes are provided in the supporting post 32, a bolt is sequentially passed through the threaded holes in the adjusting sleeve 33 and the supporting post 32, and the nut is tightened on the bolt, thereby fixing the position of the supporting post 32 in the adjusting sleeve 33; the locking member can also be a combination of a positioning pin and a positioning hole, that is, a plurality of positioning holes are provided in the axial direction on both the adjusting sleeve 33 and the supporting post 32, and the positioning pin is inserted into the positioning holes in the adjusting sleeve 33 and the supporting post 32, thereby fixing the position of the supporting post 32 in the adjusting sleeve 33. The position of the supporting post 32 in the adjusting sleeve 33 is fixed by the provided locking member, and such a configuration is possible. In this embodiment, the locking member is a combination of a bolt and a nut.

[0046] In this embodiment, the support rod 32 is nested in the adjustment sleeve 33, so that the operator can flexibly adjust the axial position of the support rod 32 on the adjustment sleeve 33 according to different detection requirements, and then flexibly adjust the position of the roundness detection rod 31 to ensure that the roundness detection rod 31 is always in contact with the annular structure workpiece 4.

[0047] Example 4:

[0048] Reference Figure 1 and Figure 2 This embodiment is a tool for detecting the roundness of an annular workpiece. Based on the third embodiment, the roundness detection assembly 3 further includes a fixing seat 34. The fixing seat 34 is connected to the mounting base 1; the adjustment sleeve 33 is connected to the fixing seat 34, and the plane of the fixing seat 34 is parallel to the radial direction of the adjustment sleeve 33.

[0049] In this embodiment, the fixing seat 34 is connected to the mounting base 1 to facilitate stable support of the supporting pole 32. During the roundness detection process, the roundness detection rod 31 is ensured to remain stable, thereby further improving the accuracy of the roundness detection result.

[0050] Example 5:

[0051] Reference Figure 1 and Figure 2 This embodiment is a tool for detecting the roundness of an annular structure workpiece. Based on Example 3, the mounting portion 12 is provided with multiple layers, and the multiple layers of mounting portions 12 are distributed along the axial direction of the annular structure workpiece 4.

[0052] In this embodiment, the mounting portion 12 is provided with multiple layers, and the operator can install multiple annular structure workpieces 4 at the same time. By adjusting the axial position of the roundness detection rod 31 on the supporting vertical rod 32, the roundness detection of multiple annular structure workpieces 4 can be achieved, thereby improving work efficiency.

[0053] Example 6:

[0054] Reference Figure 1 This embodiment is a tool for detecting the roundness of a ring-shaped workpiece, and the cross section of the mounting portion 12 is a regular octagon.

[0055] In this embodiment, the cross-section of the mounting portion 12 is a regular octagon, so that the mounting portion 12 is evenly stressed when bearing the weight and detection force of the annular structure workpiece 4, thereby reducing stress concentration and extending the service life of the roundness detection tooling for the annular structure workpiece.

[0056] Example 7:

[0057] Reference Figure 1 This embodiment is a tool for detecting the roundness of a ring-shaped workpiece, and the cross section of the support portion 11 is a regular octagon.

[0058] In this embodiment, the cross section of the support portion 11 is a regular octagon, so that the support portion 11 is evenly stressed when bearing the weight of the mounting portion 12, thereby reducing stress concentration and extending the service life of the roundness detection tooling for annular structure workpieces.

[0059] The working principle of the roundness detection tool for an annular structure workpiece of the present invention is as follows: first, the annular structure workpiece 4 is placed on the mounting base 1; then, the first connecting portion 211 of each fixing member 21 is connected to the annular structure workpiece 4, and the second connecting portion 212 of each fixing member 21 is connected to the mounting base 1, so that the installation of the annular structure workpiece 4 is realized; the axial position of the supporting vertical rod 32 on the adjusting sleeve 33 is adjusted according to the position of the annular structure workpiece 4, and is adjusted to the end of the roundness detection rod 31 directly contacting the inner surface of the annular structure workpiece 4, and the position of the supporting vertical rod 32 in the adjusting sleeve 33 is fixed by the locking member; then, the roundness detection rod 31 is driven to rotate one circle around the axis of the supporting vertical rod 32, and during this process, the end of the roundness detection rod 31 will slide along the inner surface of the annular structure workpiece 4.

[0060] If there is always a gap-free state between the end of the roundness detection rod 31 and the inner surface of the annular structure workpiece 4 during the process of the roundness detection rod 31 rotating one circle, it can be judged that the roundness of the annular structure workpiece 4 meets the requirements. If there is a change in the gap between the roundness detection rod 31 and the inner surface of the annular structure workpiece 4 during the process of the roundness detection rod 31 rotating one circle, that is, sometimes they are in contact and sometimes they are separated, it indicates that there is a deviation in the roundness of the annular structure workpiece 4, which does not meet the roundness requirements and requires further analysis or adjustment.

[0061] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
