[0031] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic diagram of an embodiment of the measurement auxiliary device of the application; Figure 2 is a structural schematic diagram of an embodiment of the auxiliary assembly of the application; Figure 3 is a structural schematic diagram of an embodiment of the pipeline of the application. The measurement auxiliary device 1 provided by the embodiment of the application is applied to assist in measuring a plurality of processing areas 21 on a pipeline 2. The measurement of the processing areas 21 on the pipeline 2 can be measurement of processing angles, processing sizes, etc. of the processing areas 21; the processing areas 21 can be processing through holes, etc.

[0032] Specifically, since the pipeline 2 has a plurality of processing areas 21, different processing areas 21 are located at different positions on the pipeline 2, in the prior art, a reference surface is generally selected to assist in measuring all the processing areas 21 on the pipeline 2, then part of the processing areas 21 has an angle with the reference surface, which is easy to reduce the measurement accuracy of the processing areas 21, and the measurement conditions of the same batch of pipelines 2 are not unified, which leads to that the yield of the pipeline 2 cannot be accurately judged.

[0033] The measurement auxiliary device 1 provided by the embodiment comprises an auxiliary assembly 11, the auxiliary assembly 11 is provided with a through hole 111, the through hole 111 is used for penetrating the opposite two surfaces of the auxiliary assembly 11, and the shape of the through hole 111 corresponds to the shape of the pipeline 2, so as to allow the pipeline 2 to be arranged in the through hole 111. Wherein, the auxiliary assembly 11 is also provided with a plurality of reference surfaces 112, the plurality of reference surfaces 112 are arranged around the opposite two surfaces provided with the through hole 111, and are used as the measurement reference surface of the pipeline 2 located in the through hole 111.

[0034] As shown in Figure 1 , when the pipeline 2 is arranged on the auxiliary assembly 11 through the through hole 111, the plurality of reference surfaces 112 are arranged around the pipe wall of the pipeline 2, that is, the plurality of reference surfaces 112 can provide the measurement reference surface for the measurement of the processing area 21 on the pipeline 2, different processing areas 21 can correspond to different reference surfaces 112, improve the measurement accuracy of the processing area 21 on the pipeline 2, and improve the user experience of using the measurement auxiliary device 1.

[0035] Optionally, please refer to Figure 1 and Figure 2 , each reference surface 112 is provided with a hollow hole 113, the hollow hole 113 is communicated with the through hole 111, and is used for exposing the processing area 21 on the pipeline 2, so as to facilitate the measurement of the processing area 21.

[0036] Specifically, the hollow hole 113 on the reference surface 112 is communicated with the through hole 111, that is, the hollow hole 113 can expose part of the outer surface of the pipeline 2 arranged in the through hole 111, and then, facilitate the measurement of the processing area 21 on the part of the exposed outer surface, improve the measurement efficiency of the processing area 21. Avoid the user from arranging the pipeline 2 in the through hole 111, the reference surface 112 shields the processing area 21, and affects the measurement of the processing area 21, further improves the user experience of using the auxiliary assembly 11.

[0037] It can be understood that, since the length of the pipeline 2 is greater than the length of the auxiliary assembly 11, part of the processing area 21 on the pipeline 2 may not be exposed in the hollow hole 113, may be shielded by the reference surface 112, or is located outside the auxiliary assembly 11 and is far away from the reference surface 112. Then, after the measurement of the processing area 21 exposed in the hollow hole 113, the pipeline 2 can be moved horizontally relative to the auxiliary assembly 11, the processing area 21 to be measured is moved into the auxiliary assembly 11 and is exposed in the hollow hole 113, the processing area 21 is moved to the vicinity of the reference surface 112, the measurement of the processing area 21 by the reference surface 112 is facilitated, and the measurement efficiency of the plurality of processing areas 21 on the pipeline 2 is improved.

[0038] Optionally, as Figure 3As shown, the pipe 2 has a plurality of processing areas 21, and each processing area 21 is provided with a corresponding reference surface 112.

[0039] Specifically, please refer to Figure 4 , Figure 4 is Figure 1 the structure diagram of another perspective view of the measuring auxiliary device. Since each processing area 21 is provided with a corresponding reference surface 112, that is, different processing areas 21 can be measured with the corresponding reference surface 112 as the measurement reference surface, thereby improving the measurement efficiency of the plurality of processing areas 21 on the pipe 2.

[0040] In an embodiment, the included angle formed between any two processing areas 21 on the pipe 2 can be in a complementary relationship with the included angle formed between the corresponding two reference surfaces 112. Further, it is ensured that each processing area 21 has a corresponding reference surface 112 as the measurement reference surface of the processing area 21. It can be understood that, for example, Figure 1 The radial cross-sectional shape of the auxiliary assembly 11 is a square, and Figure 4 It can be obtained that the two adjacent processing areas 21 on the pipe 2 are arranged on opposite sides of the pipe 2, that is, the included angle between the two processing areas 21 is 180°, and the corresponding two reference surfaces 112 are arranged in parallel to ensure that each processing area 21 has a reference surface 112 as the measurement reference surface to assist in measurement, thereby improving the measurement accuracy of the processing area 21.

[0041] In another embodiment, if the included angle between the two processing areas 21 is other specific values, the included angle between the corresponding reference surfaces 112 is also other values, and the radial cross-sectional shape of the auxiliary assembly 11 can not only be a square, but also be a triangle, a pentagon, a hexagon, etc., that is, the radial cross-sectional shape of the auxiliary assembly 11 can be an n-sided polygon (n is an integer greater than or equal to 3), and the angles between the plurality of internal angles in the n-sided polygon can not be equal. The specific setting position of the processing area 21 on the pipe 2 can be determined, and in the case where each processing area 21 has a corresponding reference surface 112, the present application does not limit this.

[0042] Optionally, please continue to refer to Figure 1 and Figure 4 The radial cross-sectional shape of the pipe 2 is a circle, and the measuring auxiliary device 1 further comprises a correcting member 12, and the correcting member 12 comprises at least one correcting surface. The shape of the correcting surface corresponds to the shape of the processing area 21 of the pipe 2.

[0043] The correction member 12 is arranged in the hollow hole 113, and the correction surface is used to contact the processing area 21 to correct the angle of the pipeline 2, so that the corrected processing area 21 is arranged opposite to the reference surface 112, and the accuracy of measuring the processing area 21 by taking the corresponding reference surface 112 as the measurement reference surface is improved. The height of the correction member 12 can be equal to the width of the hollow hole 113, so that when the correction member 12 is arranged in the hollow hole 113, the correction member 12 can be just arranged in the hollow hole 113 and cannot shake in the width direction of the hollow hole 113, which affects the contact between the correction surface and the processing area 21, affects the positioning efficiency of the processing area 21, and affects the correction efficiency of the correction member 12 to the pipeline 2.

[0044] In an embodiment, the processing area 21 can be a processing through hole, such as a processing through hole 21-a shown in the figure. The length of the processing through hole 21-a is greater than or equal to the width of the correction surface, that is, the processing through hole 21-a can form an effective contact plane on the curved wall of the pipeline 2, the correction surface can position the processing through hole 21-a according to the plane, correct the processing through hole 21-a to the reference surface 112, facilitate measuring the processing through hole 21-a by taking the reference surface 112 as the measurement reference surface, and improve the measurement accuracy of the processing through hole 21-a. Figure 4

[0045] Specifically, the correction member 12 is arranged in the hollow hole 113, and the correction surface can abut against the plane formed by the processing through hole 21-a and the wall of the pipeline 2, so that the processing through hole 21-a is arranged opposite to the reference surface 112. As described above, the included angle formed between any two processing areas 21 on the pipeline 2 can be complementary to the included angle formed between the corresponding two reference surfaces 112, so that if the processing through hole 21-a is corrected to be arranged opposite to the corresponding reference surface 112, the remaining processing areas 21 on the pipeline 2 can also be arranged opposite to the corresponding reference surfaces 112, and the measurement efficiency of the processing areas 21 on the pipeline 2 is improved.

[0046] In another embodiment, if the curvature of the pipeline 2 is small, that is, the curved wall is not obvious, the positioning cannot be effectively performed based on the contact plane formed by the processing through hole 21-a on the wall, so that the correction surface can be provided with a first protruding member, and the height of the first protruding member can be equal to the width of the processing through hole 21-a. When the correction member 12 is arranged in the hollow hole 113, the correction surface abuts against the plane formed by the processing through hole 21-a and the wall of the pipeline 2, and the first protruding member is arranged in the processing through hole 21-a, so that the processing through hole 21-a is arranged opposite to the reference surface 112.

[0047] ​The first protrusion, in conjunction with the machined through hole 21-a, can further improve the positioning efficiency of the straightening member 12 for the machined through hole 21-a, thereby straightening the machined hole 21-a to face the reference surface 112 and improving the measurement efficiency of the machined through hole 21-a.

[0048] In other embodiments, if the processing area 21 is as follows Figure 4 Figure 4 The through hole 21-b shown is smaller than the size of the straightening face. That is, the through hole 21-b cannot form an effective contact plane on the pipe wall of the pipe 2. The straightening face cannot position the through hole 21-b based on the plane formed by the through hole 21-b on the pipe wall of the pipe 2. Therefore, a second protrusion can be provided on the straightening face. The shape of the second protrusion corresponds to the shape of the through hole 21-b. For example, if the through hole 21-b is a circular hole, the second protrusion can be a cylinder. If the through hole 21-b is an irregular shape, the cross-sectional shape of the second protrusion can also be an irregular shape. Then, the straightening member 12 is set on the shaft of the hollow hole 113. The second protrusion can be located in the through hole 21-b. The straightening member 12 positions and corrects the through hole 21-b so that the through hole 21-b is set to correspond with the reference surface 112, thereby improving the measurement efficiency of the through hole 21-b.

[0049] By setting the straightener 12, the processing area 21 can be positioned and corrected so that the processing area 21 on the pipe 2 is aligned with the corresponding reference surface 112, thereby improving the measurement efficiency of the processing area 21.

[0050] It is understandable that a first protrusion and a second protrusion can be provided on the same straightening member 12. The first protrusion and the second protrusion can be provided on two opposite straightening surfaces of the straightening member 12. Thus, the straightening member 12 can be used to position and straighten both the machined through hole 21-a with a length greater than or equal to the width of the straightening surface and the machined through hole 21-b with a size smaller than the size of the straightening surface, thereby improving the reusability of the straightening member 12. There is no need to set different straightening members 12 based on different shapes of the processing area 21. Without affecting the setting of the straightening member 12 in the hollow hole 113, corresponding settings can be made directly on different straightening surfaces of the same straightening member 12, reducing the material cost of the straightening member 12, improving the reusability of the straightening member 12, and improving the user's experience with the measurement auxiliary device 1.

[0051] Optionally, the measurement auxiliary device 1 can further comprise a friction pad (not shown in the figure), which can be arranged in the through hole 111. For example, the friction pad can be a ring pad arranged on the inner surface of the through hole 111. When the pipe 2 is arranged in the through hole 111, the friction pad is located between the outer surface of the pipe 2 and the inner surface of the through hole 111, so as to increase the friction between the pipe 2 and the through hole 111, and fix the angle of the corrected pipe 2.

[0052] Specifically, after the setting angle of the pipe 2 is corrected by the correction member 12, so that the processing area 21 on the pipe 2 is arranged opposite to the corresponding reference surface 112, the correction member 12 needs to be removed from the hollow hole 113 to expose the processing area 21 to be measured, so as to allow the processing area 21 to be measured. After the correction member 12 is removed, if there is a moving space between the pipe 2 and the through hole 111, the corrected pipe 2 can restore the angle before correction, or move to other angles, so that the processing area 21 is not arranged opposite to the corresponding reference surface 112, and the measurement accuracy of the processing area 21 cannot be guaranteed.

[0053] The embodiment provides the friction pad arranged in the through hole 111, so as to increase the friction between the pipe 2 and the through hole 111, avoid the pipe 2 from moving relative to the through hole 111 after the correction member 12 is removed, fix the angle of the corrected pipe 2, and improve the measurement efficiency of the processing area 21 on the pipe 2.

[0054] Optionally, when the radial cross-sectional shape of the pipe 2 is an irregular shape, any one of the plurality of reference surfaces 112 is arranged opposite to the special-shaped surface of the pipe 2. Since each processing area 21 has a corresponding reference surface 112, when the special-shaped surface of the pipe 2 is opposite to any one of the plurality of reference surfaces 112, the remaining processing areas 21 on the pipe 2 are also arranged opposite to the corresponding reference surfaces 112, and it is not necessary to additionally arrange the correction member 12 to perform positioning correction. In this way, the measurement efficiency of the processing area 21 is improved, and the positioning effect of the pipe 2 is improved.

[0055] To sum up, the measurement auxiliary device 1 provided in the application comprises the auxiliary assembly 11, which can provide the plurality of processing areas 21 on the pipe 2 with corresponding reference surfaces 112, so as to serve as the measurement reference surface when the processing area 21 is measured, and improve the measurement efficiency of the processing area 21.

[0056] Meanwhile, when the radial cross-sectional shape of the pipe 2 is circular, the measurement auxiliary device 1 further comprises the correction member 12, which can perform positioning correction on the processing area 21 on the pipe 2, so that the processing area 21 on the pipe 2 is arranged opposite to the corresponding reference surface 112, improve the measurement efficiency of each processing area 21, improve the practicability of the measurement auxiliary device 1, and improve the user experience of the measurement auxiliary device 1.

[0057] The application also provides a pipe measuring device (not shown in the figure), comprising the measuring auxiliary device 1 and a measuring device (not shown in the figure), the measuring device is used for measuring the machining area 21 of the pipe 2 located on the auxiliary assembly 11 to obtain machining data of the machining area 21.

[0058] The above merely describes the embodiments of the application, and does not limit the patent scope of the application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
