Description

Technical Field

[0001] This application relates to the field of sleeve concentricity testing technology, and in particular to a sleeve concentricity testing tool. Background Technology

[0002] Sleeve-type components are widely used in industrial production, especially in machinery and automobile manufacturing, where their performance directly affects the efficiency and reliability of the entire machine. To ensure that sleeve quality meets design requirements, accurate measurement of its geometric dimensions is crucial. Concentricity is one of the key indicators for measuring sleeve quality, directly affecting the operational stability and service life of the assembled parts. With the increasing precision requirements of the manufacturing industry, how to efficiently and accurately measure the concentricity of sleeves has become an important issue for industry development.

[0003] Currently, in actual production processes, common methods for detecting the concentricity of sleeves mainly include manual measurement and specialized equipment testing. Manual measurement typically uses tools such as vernier calipers and dial indicators to measure the inner and outer diameters of the sleeve point by point, and then calculates the concentricity deviation. Specialized equipment testing, on the other hand, relies on optical projectors or laser scanning devices to achieve automated testing. While these traditional methods can meet testing requirements to some extent, they still have many limitations in terms of ease of operation, applicability, and testing accuracy.

[0004] The methods described above generally suffer from complex adjustments and low testing efficiency, especially when dealing with sleeves of different specifications. Frequent fixture changes or equipment recalibration are required, leading to lengthy testing times and significant errors. Furthermore, existing testing methods struggle to simultaneously meet the requirements of high precision and versatility, limiting their application in diverse production environments. Utility Model Content

[0005] The purpose of this application is to provide a sleeve concentricity inspection tool that can effectively improve the efficiency and accuracy of sleeve concentricity detection.

[0006] The sleeve concentricity inspection tool provided in this application adopts the following technical solution:

[0007] A sleeve concentricity inspection tool includes a base, a sleeve component, and a cylindrical component. The sleeve component is detachably mounted on the base, and a hollow portion is formed in the center of the sleeve component. The cylindrical component is detachably mounted on the base and is located at the center of the hollow portion of the sleeve component.

[0008] By adopting the above technical solution, this application provides a sleeve concentricity inspection tool, which can detect the concentricity of sleeves. Specifically, the tool consists of a base, a sleeve component detachably mounted on it, and a cylindrical component located at the center of the hollowed-out portion of the sleeve component. This facilitates quick assembly and adjustment, and allows for the replacement of different sleeve components and cylindrical components according to different sleeve sizes. In use, the sleeve is simply inserted between the sleeve component and the cylindrical component at different angles to determine whether the concentricity is qualified, thus improving the detection efficiency and accuracy.

[0009] Preferably, the sleeve has several connecting parts around its hollowed-out portion, and the base has several threaded holes at positions corresponding to the connecting parts of the sleeve. The threaded holes and the connecting parts are connected by threads, allowing the sleeve to be detachably mounted on the base.

[0010] By adopting the above technical solution, this application achieves a detachable connection between the sleeve and the base through the connecting part. Specifically, by setting the connecting part around the hollow part of the sleeve and opening threaded holes at the corresponding positions on the base, the sleeve is fixed to the base by means of threaded connection, thereby facilitating the installation and replacement of the sleeve and improving the flexibility and practicality of the testing tool.

[0011] Preferably, the base has a cylindrical connecting hole at its center, the diameter of which is the same as the diameter of the cylindrical component, and the bottom of the cylindrical component is inserted into the cylindrical connecting hole so that the cylindrical component can be detachably installed on the base.

[0012] By adopting the above technical solution, precise assembly between the cylindrical part and the base is achieved. Specifically, the cylindrical connecting hole is located at the center of the base, and its diameter matches the diameter of the cylindrical part, ensuring that the cylindrical part can be accurately inserted into the center position of the base, thereby improving the concentricity detection accuracy between the sleeve and the cylindrical part. The detachable installation is achieved by inserting the bottom of the cylindrical part into the cylindrical connecting hole, which not only facilitates operation but also allows for quick replacement or adjustment of the cylindrical part's position when needed, enhancing the flexibility and practicality of the inspection fixture.

[0013] Preferably, the cross-section of the hollowed-out portion of the sleeve is square.

[0014] By adopting the above technical solution, this application sets the cross-section of the hollowed-out part to a square, which ensures the regularity of the internal space of the sleeve component and facilitates accurate measurement of concentricity deviation during subsequent testing. Specifically, the square design helps to clearly define the boundary of the testing area, improving the consistency and reliability of the testing results.

[0015] Preferably, the side length of the cross-section of the hollow part is 16.6±0.01mm, and the diameter of the cylindrical part is 12.0±0.005mm.

[0016] By adopting the above technical solution, this application can precisely control the dimensions of the cross-section of the hollowed-out part of the sleeve and the diameter of the cylindrical part, ensuring the fitting accuracy between the two. Specifically, limiting the side length of the cross-section of the hollowed-out part to 16.6±0.01mm can effectively ensure the regularity of the shape and the consistency of processing of the hollowed-out part, thereby improving the stability during inspection; at the same time, setting the diameter of the cylindrical part to 12.0±0.005mm not only meets the requirement of precise assembly with the cylindrical connection hole of the base, but also further improves the accuracy of concentricity detection.

[0017] Preferably, the height of the hollowed-out portion is 30.0±0.01mm, and the height of the cylindrical part is 63.0±0.1mm.

[0018] By adopting the above technical solution, this application achieves specific limitations on the height of the hollowed-out portion of the sleeve and the height of the cylindrical component. Specifically, setting the height of the hollowed-out portion to 30.0±0.01mm ensures sufficient structural strength of the sleeve during inspection, while also facilitating its use with other components. Setting the height of the cylindrical component to 63.0±0.1mm ensures assembly accuracy while further improving the accuracy and reliability of the inspection. The combined effect of these two dimensional designs allows the inspection fixture to more accurately measure the concentricity of the sleeve in practical applications.

[0019] Preferably, the sleeve connecting part includes a first cylindrical cavity and a second cylindrical cavity that are interconnected, the second cylindrical cavity being close to the base, and the diameter of the first cylindrical cavity being larger than the diameter of the second cylindrical cavity.

[0020] By adopting the above technical solution, this application achieves a reliable connection between the sleeve and the base. Specifically, by setting a first cylindrical cavity and a second cylindrical cavity that are interconnected, and making the diameter of the first cylindrical cavity larger than the diameter of the second cylindrical cavity, a stepped structure is formed. This structure can enhance the stability of the connection and prevent misalignment or loosening during the connection process. This design not only improves assembly accuracy but also facilitates disassembly and maintenance, thereby improving testing efficiency and reliability.

[0021] Preferably, the diameter of the first cylindrical cavity is 8.5±0.05mm, and the diameter of the second cylindrical cavity is 6.0±0.05mm.

[0022] By adopting the above technical solution, this application achieves a precise connection between the sleeve and the base. Specific effects include: the diameter of the first cylindrical cavity is set to 8.5±0.05mm, ensuring sufficient contact area during threaded connection and improving connection strength and stability. The diameter of the second cylindrical cavity is set to 6.0±0.05mm, reducing material usage while maintaining structural strength and optimizing positioning accuracy during assembly.

[0023] Preferably, the height of the first cylindrical cavity is 25.0±0.1mm, and the height of the second cylindrical cavity is 5.0±0.1mm. By adopting the above technical solution, the specific structural dimensions of the sleeve connection are optimized. Specific effects include: setting the height of the first cylindrical cavity to 25.0±0.1mm ensures a stable connection between the sleeve and the base, while facilitating positioning during assembly. Setting the diameter of the second cylindrical cavity to 5.0±0.1mm further improves the connection strength, ensures the reliability of the threaded connection, and reduces the risk of loosening.

[0024] Preferably, the top of the cylindrical component has a first chamfer, and the bottom of the cylindrical component has a second chamfer.

[0025] By adopting the above technical solution, the first chamfer on the top of the cylindrical part can facilitate the guiding and positioning of the cylindrical part and the component to be tested during assembly, and reduce damage caused by collision during assembly; the second chamfer on the bottom of the cylindrical part helps to improve the smoothness of the cylindrical part being inserted into the cylindrical connecting hole of the base, while further enhancing the overall aesthetics and safety of the structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application achieves efficient detection of sleeve concentricity by detachably mounting the sleeve on the base and inserting the cylindrical part into the center of the sleeve's hollow part, thus solving the problems of complex operation and low detection efficiency caused by frequent changes of fixtures or calibration equipment in traditional methods.

[0028] 2. The detachable connection between the sleeve and the base and the position fixing method of the cylindrical part in this application enable the inspection tool to be quickly adapted to sleeves of different specifications, improving the versatility of the inspection device and meeting the needs of diverse production environments;

[0029] 3. The precise dimensional matching design between the hollowed-out part and the cylindrical part in this application ensures the accuracy of positioning during the inspection process, thereby significantly improving the accuracy of concentricity detection. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application provides a clear and complete description of the technical solution. The described embodiments are merely possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can combine the embodiments of this utility model to obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this utility model.

[0037] The inventors of this application have discovered that traditional methods for detecting the concentricity of sleeves suffer from problems such as complex adjustments and low detection efficiency. To address this, this application mainly employs a sleeve concentricity gauge, which achieves efficient and accurate detection results through modular component design, thereby simplifying the adjustment process and improving detection accuracy and efficiency. The following is a further detailed description of this application.

[0038] This application provides a sleeve concentricity inspection tool, referring to... Figure 1 and Figure 2 The device includes a base 1, a sleeve 2, and a cylindrical component 3. The sleeve 2 is detachably mounted on the base 1, and has a hollow section 21 at its center. The cylindrical component 3 is detachably mounted on the base 1 and is located at the center of the hollow section 21 of the sleeve 2. This structural design makes the entire device highly flexible, allowing it to adapt to various sleeve inspection requirements by disassembling and replacing different sleeves 2 and cylindrical components 3.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment of the application, the base 1 and the sleeve 2 are fixedly connected by four connecting parts 22. These connecting parts 22 are respectively arranged around the hollow part 21 of the sleeve 2, and are engaged with corresponding positions on the base 1 through threaded holes 11, and are firmly connected by bolts. For example, a standard 4-M5 hex bolt can be used as the connecting element, or a self-tapping screw can be selected to improve the ease of installation and removal.

[0040] like Figure 2 , Figure 4 and Figure 5 As shown, the base 1 in this embodiment has a circular cylindrical connecting hole 12 in the center to match the size requirements of the cylindrical part 3. To ensure assembly accuracy, the diameter of the cylindrical connecting hole 12 is strictly controlled to be the same as the diameter of the cylindrical part 3 itself, allowing a certain gap between them without affecting the positioning accuracy. After inserting the cylindrical part 3 into the corresponding position of the base 1, tightening the fixing screws completes the assembly.

[0041] In the specific implementation process, the cross-section and cylindrical dimensions and shape of the hollow part 21 of the sleeve 2 can be adjusted according to the actual testing requirements. In this embodiment, the cross-section of the hollow part 21 of the sleeve 2 is square, the side length of the cross-section of the hollow part 21 is 16.6±0.01mm, the diameter of the cylindrical part 3 is 12.0±0.005mm, the height of the hollow part 21 is 30.0±0.01mm, the height of the cylindrical part 3 is 63.0±0.1mm, the height of the base 1 is 15.0±0.05mm, the diameter of the cylindrical connecting hole 12 is 12.0±0.005mm, and the threaded hole 11 is a 4-M5 thread.

[0042] like Figure 2 and Figure 4 As shown, the connecting portion 22 of the sleeve component 2 in this embodiment includes a first cylindrical cavity 221 and a second cylindrical cavity 222 that are interconnected. The second cylindrical cavity 222 is close to the base 1. The diameter of the first cylindrical cavity 221 is larger than the diameter of the second cylindrical cavity 222, thereby enhancing the stability of the connecting portion 22 and preventing misalignment or loosening during the connection process. In specific implementation, the diameter and height of the first cylindrical cavity 221 and the second cylindrical cavity 222 can be adjusted according to actual testing requirements. In this embodiment, the diameter of the first cylindrical cavity 221 is 8.5±0.05mm, the diameter of the second cylindrical cavity 222 is 6.0±0.05mm, the height of the first cylindrical cavity 221 is 25.0±0.1mm, and the height of the second cylindrical cavity 222 is 5.0±0.1mm.

[0043] like Figure 5As shown, the cylindrical component 3 in this embodiment has a first chamfered portion 31 at its top and a second chamfered portion 32 at its bottom. The first chamfered portion 31 facilitates the guiding and positioning of the cylindrical component 3 during assembly with the component to be tested, reducing damage caused by collisions during assembly. The second chamfered portion 32 helps improve the smoothness of the cylindrical component 3 inserting into the cylindrical connecting hole 12 of the base 1. In specific implementation, the dimensions of both the first chamfered portion 31 and the second chamfered portion 32 are C0.3mm.

[0044] The implementation principle of this embodiment is as follows: The inspection tool of this application embodiment consists of a base 1, a sleeve 2 that can be detachably installed on it, and a cylindrical part 3 located at the center of the hollow part 21 of the sleeve 2. It is convenient for quick assembly and adjustment. Different sleeve 2 and cylindrical part 3 can be replaced according to different sleeve sizes. When in use, the sleeve can be directly inserted between the sleeve 2 and the cylindrical part 3 from different angles to determine whether the concentricity is qualified, which improves the detection efficiency and accuracy.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
