Description

Technical Field

[0001] This disclosure relates to the technical field of borehole position measuring equipment, and more particularly to a detection device. Background Technology

[0002] During the production of curved surface components, it is necessary to measure the positional parameters between the holes on the surface to ensure that the deviation between the measured holes can guarantee the assembly accuracy of the component. If the deviation between the holes is large, it may cause the component to fail to assemble correctly, affecting the overall performance and appearance. Therefore, confirming the relative positional accuracy between the holes on curved surface components is of great importance.

[0003] In existing technologies, since the holes to be inspected are located in three different directions, the accuracy of micrometers and rulers cannot meet the measurement requirements. To solve this problem, a two-dimensional measuring instrument is used to measure each hole one by one. This involves placing the part to be measured on a worktable and using a probe to measure the position of the holes. The measurement data is processed by a computer to provide accurate hole distance results, which greatly wastes time and labor costs. At the same time, it requires a high level of technical skill from the operators and poses a risk of inaccurate data due to human error. Utility Model Content

[0004] One of the technical problems that this disclosure aims to solve is: how to ensure the accuracy of the measurement of the three holes on a curved surface component while also reducing the measurement time and improving the measurement efficiency.

[0005] To address the aforementioned technical problems, this disclosure provides a detection device, comprising:

[0006] A curved support component is provided with a mating surface, and the curvature of the mating surface is adapted to the curvature of the component to be tested.

[0007] A measuring component is used to detect the positional accuracy between at least three holes on a part under test;

[0008] The measuring component includes a positioning element, a first measuring element, and a second measuring element. The positioning element, the first measuring element, and the second measuring element are all inserted into the corresponding holes through the curved support.

[0009] In some embodiments, the first measuring element is disposed between the positioning element and the second measuring element;

[0010] Both the positioning element and the second measuring element are used for fastening between the end of the curved support and the part to be measured.

[0011] In some embodiments, the end of the positioning member away from the component to be measured is provided with a threaded surface, and the external thread of the threaded surface of the positioning member is connected with a bolt.

[0012] Bolts are used to fasten one end of a curved support to the part to be tested via a positioning element.

[0013] In some embodiments, the surface of the curved support that contacts the bolt is a plane.

[0014] In some embodiments, both the first measuring element and the second measuring element include a handle and a plug, with the handle located at the end of the plug away from the curved support.

[0015] In some embodiments, the insertion post of the second measuring element is provided with a stop bar;

[0016] The curved support is provided with a bent-type snap-fit ​​groove, and the stop bar extends along the snap-fit ​​groove.

[0017] In some embodiments, the snap-fit ​​slot has a first groove and a second groove, and the first groove and the second groove are in communication with each other;

[0018] The extension direction of the first groove is consistent with the insertion direction of the second measuring element, and the extension direction of the second groove is perpendicular to the extension direction of the first groove.

[0019] In some embodiments, an elastic element is provided between the end of the handle and the curved support that is away from the part to be tested, and the elastic element is used to reset the plug in the direction of the handle.

[0020] In some embodiments, the elastic element is a return spring, which is arranged around the periphery of the plug post.

[0021] In some embodiments, the curved support includes a first housing and a second housing, which are engaged with each other.

[0022] Through the above technical solution, the detection device provided in this disclosure, by setting a curved support member with a mating surface whose curvature matches the curvature of the component under test, enables the device to completely fit the exterior of the component under test during measurement, thereby improving measurement accuracy. The curved support member is equipped with positioning members, a first measuring member, and a second measuring member, etc., for insertion into corresponding holes on the component under test. After the curved support member fits into the component under test, whether the positioning members, the first measuring member, and the second measuring member can smoothly insert into their corresponding holes serves as a benchmark for determining whether the positional accuracy between the holes on the component under test meets the requirements. The technical effects of adopting the above technical solution are as follows:

[0023] First, it replaces the existing two-dimensional measurement method with a model comparison method, which is more suitable for mass-produced test parts, reduces a lot of time spent on equipment debugging and measurement preparation, and is low in cost, simple to operate, and easy to promote.

[0024] Secondly, the measuring assembly is equipped with at least three measuring components, including a positioning component, a first measuring component, and a second measuring component. This not only allows for the measurement of the positional parameters of the hole spacing but also enables the accurate measurement of the curvature relationship between the holes, further improving the measurement accuracy.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure depending on the specific circumstances. When a particular device is described as being located between a first device and a second device, an intermediary device may or may not be present between the particular device and the first or second device.

[0035] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0037] The technical approach of this application is as follows:

[0038] Firstly, by integrating the curved support 100 and the measuring components, the hole spacing and curvature parameters of the positioning component 210, the first measuring component 220, and the second measuring component 230 meet the required values. The connection between the positioning component 210, the first measuring component 220, and the second measuring component and the corresponding hole positions is used as the basis for judging whether the hole positions on the component under test 10 meet the required values. This eliminates the need for redundant components such as the two-dimensional detection method control system and camera in existing technologies, resulting in low cost, ease of operation, and a significant reduction in detection time.

[0039] Secondly, the connection process between the testing device and the component under test 10 has been expanded. In actual operation, the positioning component 210 is first fixed to its corresponding hole by the cooperation between the bolt 20 and the curved support component 100. Then, the second measuring component 230 is inserted into its corresponding hole. The second measuring component is fixed relative to the curved support component 100 by the stop bar 203. The curved support component is fixed at both ends relative to the component under test 10 in sequence. Finally, it is checked whether the first measuring component 220 can be inserted into its corresponding hole to determine whether the positional accuracy between the holes on the component under test 10 meets the standard. The entire testing process can be completed by one person. Moreover, by fixing the curved support component 100 and the component under test 10, the mating surface can be tightly attached to the surface of the component under test 10, and the measured curvature coefficient is more accurate.

[0040] Furthermore, the structures of the first measuring element 220 and the second measuring element 230 are improved. By setting the elastic element 300, the plug pin 202 has a reset and rebound function, which further reduces the time for the operator to reset the plug pin 202 through the handle 201 after the test.

[0041] Finally, the structure of the curved support 100 is improved by using the interlocking of the first and second housings to facilitate the detachable installation of the positioning component 210, the first measuring component 220, the second measuring component 230, or other related components, thereby enhancing the functionality of the product.

[0042] It should be noted that the positioning element 210 and the second measuring element 230 can also be provided with multiple measuring elements other than the first measuring element 220 to adapt to usage scenarios with more than 3 holes.

[0043] The above technical solution will be described in detail below. Example

[0044] like Figure 1 As shown, this example provides a detection device, including:

[0045] The curved support 100 has a mating surface, and the curvature of the mating surface is adapted to the curvature of the component 10 to be tested.

[0046] A measuring component is used to detect the positional accuracy between at least three holes on the part under test 10;

[0047] The measuring components include a positioning element 210, a first measuring element 220, and a second measuring element 230. The positioning element 210, the first measuring element 220, and the second measuring element 230 are all inserted into the corresponding holes through the curved support element 100.

[0048] Specifically, by setting a curved support 100, which has a mating surface and whose curvature matches the curvature of the component 10 to be measured, the device can completely fit the outside of the component 10 during measurement, improving measurement accuracy. The curved support 100 is provided with positioning components 210, first measuring components 220, and second measuring components 230 for insertion into corresponding holes on the component 10. After the curved support 100 fits into the component 10, whether the positioning components 210, first measuring components 220, and second measuring components 230 can be smoothly inserted into their corresponding holes serves as a benchmark for whether the positional accuracy between the holes on the component 10 meets the requirements. The technical effects of the above technical solution are as follows:

[0049] First, the model comparison method replaces the existing two-dimensional measurement method, which is more suitable for mass-produced test components 10, reduces a lot of time spent on equipment debugging and measurement preparation, and is low in cost, simple to operate, and suitable for promotion.

[0050] Secondly, the measuring assembly is equipped with at least three measuring components, including a positioning component 210, a first measuring component 220, and a second measuring component 230. This not only allows for the measurement of the positional parameters of the hole spacing but also enables the accurate measurement of the curvature relationship between the holes, further improving the measurement accuracy.

[0051] Furthermore, the first measuring element 220 is disposed between the positioning element 210 and the second measuring element 230;

[0052] The positioning element 210 and the second measuring element 230 are both used for fastening between the end of the curved support 100 and the part to be measured 10.

[0053] Since the object of measurement in this application is a curved surface component 10 with more than three holes, the curved surface support 100 should be securely connected to the component 10 during measurement to ensure that the contact surface of the curved surface support 100 is tightly fitted to the surface of the component 10. To address the above problem, the following improvements are made:

[0054] Specifically, the first measuring element 220 is positioned between the positioning element 210 and the second measuring element 230, thus forming a three-point connection structure that meets the prerequisite for curved surface connection. Both the positioning element 210 and the second measuring element 230 are used for fastening the end of the curved surface support 100 to the component 10 to be measured. The fastening connection method is as follows:

[0055] Furthermore, the end of the positioning member 210 facing away from the part to be measured 10 is provided with a threaded surface, and the external thread of the threaded surface of the positioning member 210 is connected with a bolt 20.

[0056] Bolt 20 is used to fasten one end of curved support 100 to the part to be tested 10 via positioning element 210.

[0057] Specifically, after the positioning member 210 is inserted into the corresponding hole, the bolt 20 and the threaded surface cooperate, with the positioning member 210 as the guide, the bolt 20 gradually applies pressure to the curved support member 100, thereby making the positioning member 210 firmly connected to the curved support member 100, and fixing the curved support member 100 along one side of the positioning member 210.

[0058] It should be noted that, in order to enhance the force balance between the bolt 20 and the curved support 100, in this embodiment, the surface of the curved support 100 that contacts the bolt 20 is a plane.

[0059] Furthermore, such as Figure 2 and Figure 3 As shown, both the first measuring element 220 and the second measuring element 230 include a handle 201 and a plug 202. The handle 201 is located at the end of the plug 202 away from the curved support 100.

[0060] The first measuring component 220 is operated using a handle 201 and a connector 202, which facilitates the operator's insertion and removal of the connector 202 via the handle 201. Simultaneously, the structural design of the connector 202 lays the foundation for the subsequent fixing of the second measuring component relative to the curved support 100. The fixing method is as follows:

[0061] Furthermore, the insertion post 202 of the second measuring piece is provided with a stop bar 203;

[0062] The curved support 100 is provided with a bent snap-fit ​​groove, and the stop bar 203 extends along the snap-fit ​​groove.

[0063] Furthermore, the snap-fit ​​groove is provided with a first groove 101 and a second groove 102, and the first groove 101 and the second groove 102 are interconnected.

[0064] The extension direction of the first groove 101 is consistent with the insertion direction of the second measuring element, and the extension direction of the second groove 102 is perpendicular to the extension direction of the first groove 101.

[0065] Specifically, the curved support 100 is provided with a bent snap-fit ​​groove, and the stop bar 203 extends along the snap-fit ​​groove. The snap-fit ​​groove has a first groove 101 and a second groove 102, which are interconnected. The first groove 101 is aligned with the insertion direction of the second measuring element 230, providing sufficient space for the second measuring element 230 to be inserted into the corresponding hole. After the second measuring element 230 is inserted into the corresponding hole, the second groove 102 is located at the position of the stop bar 203, and the extension direction of the second groove 102 is aligned with that of the first groove 101. Since the extension direction of 1 is perpendicular, at this time, it is only necessary to rotate the second measuring piece 230, and the stop bar 203 can enter the second groove 102 to fix the second measuring piece 230 in the existing position. Combined with the fixing of the positioning piece 210 by the bolt 20 described above, the two ends of the curved support piece 100 are fixed. The whole process can be completed by only one person, and the operation is convenient and simple. After the two ends of the curved support piece 100 are fixed, it can be determined whether the part to be tested 10 is qualified by observing whether the first measuring piece 220 can be inserted into its corresponding hole.

[0066] It can be inferred that if the second measuring piece 230 cannot be inserted into the corresponding hole after the fixed positioning piece 210 is in place, the operator can directly determine that the part to be tested 10 is a non-conforming product.

[0067] Furthermore, an elastic element 300 is provided between the handle 201 and the curved support 100 at the end away from the part to be tested 10. The elastic element 300 is used to reset the plug post 202 toward the handle 201.

[0068] Furthermore, the elastic element 300 is a return spring, which is arranged around the periphery of the insertion post 202.

[0069] In this embodiment, the elastic element 300 is set using a return spring, that is, the return spring is arranged around the periphery of the insertion post 202. During the measurement process, the operator first fixes the positioning element 210 and bolt 20 to the curved support element 100 on the part to be measured 10. After the second measuring element 230 at the other end is inserted into the corresponding hole, the second measuring element 230 is fixed by setting the stop bar. Then, the insertion post 202 is inserted into the corresponding hole through the handle 201. If it can be inserted smoothly, it proves that the product is qualified. Then, the first measuring element 220 is released and the second measuring element 230 is rotated. The first measuring element 220 and the second measuring element 230 can directly return to the initial state under the action of the return spring, which reduces the operator's reset time and further improves work efficiency.

[0070] Furthermore, the curved support 100 includes a first housing and a second housing, which are engaged with each other.

[0071] like Figure 2 As shown, in this embodiment, the curved support 100 is configured by fastening the first housing and the second housing together. The fastening method can be configured by using a matching serrated connection between the first housing and the second housing, or by using a through threaded hole and fixing it with bolts 20.

[0072] After the first housing and the second housing are fastened together, one side forms a mating surface that connects to the component to be measured 10, and the other side forms an insertion hole for the positioning member 210, the first measuring member 220 and the second measuring member 230 in the measuring assembly to be inserted. The insertion hole penetrates the mating surface.

[0073] It should be noted that designers need to set the relevant curvature and socket layout of the first and second housings according to the specific structure and requirements of the component under test 10. The number of sockets can be more than the number required by the measuring components to increase the applicable scenarios of this device.

[0074] In summary, the detection method between the detection device and the component 10 under test provided in this embodiment is as follows:

[0075] S10. Through the cooperation between the bolt 20 and the curved support 100, the positioning member 210 is fixed in its corresponding hole position by the compression of the bolt 20 and the threaded surface.

[0076] S20. Insert the second measuring element 230 into its corresponding hole, rotate the second measuring element 230 to drive the stop bar 203 from the first groove 101 on the curved support 100 to the second groove 102, and use the abutment between the edge of the second groove 102 and the stop bar 203 to achieve limiting and fixing.

[0077] S30. Insert the first measuring element 220 into its corresponding hole to determine whether the positional accuracy between the holes on the component to be measured 10 meets the standard.

[0078] Using the above method, the entire testing process can be completed by a single person. Moreover, by fixing the curved support 100 and the test component 10, the mating surface can be tightly attached to the surface of the test component 10, resulting in a more accurate measured curvature coefficient. This method is more suitable for mass-produced test components 10, reducing a significant amount of time spent on equipment debugging and measurement preparation. Furthermore, it is low-cost, easy to operate, and suitable for widespread application.
