[0002] In modern manufacturing, with the accelerated pace of product updates and the growing demand for personalized customization, the types and quantities of inspection tools required in the production process have increased dramatically. As key tooling to ensure product dimensional accuracy and quality consistency, the design and management of inspection tools directly impact production costs, warehousing efficiency, and production response speed. Especially in the manufacturing of complex parts such as automobiles and aerospace, traditional inspection tools are often designed specifically for a single vehicle model or part, requiring companies to invest heavily in manufacturing inspection tool base plates of different specifications. Therefore, the flexibility and commonality of inspection tools have become important development directions for cost reduction and efficiency improvement in the industry.

[0003] In existing technologies, inspection fixtures typically consist of a fixed base plate, positioning components, inspection components, and auxiliary supports. The dimensions of the base plate and the positioning reference need to be customized according to the shape parameters of specific parts. To meet the inspection needs of different vehicle models or parts, companies need to design and manufacture inspection fixture base plates separately for each product, occupying a large area of ​​factory space for storage. At the same time, they face problems such as high fixture idle rate, low changeover efficiency, and high manufacturing costs. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible inspection tool that can reduce the investment in the inspection tool base plate, reduce the footprint of the inspection tool, and lower the manufacturing cost of the inspection tool.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A flexible inspection tool, comprising:

[0007] The base plate module includes a fixture base plate, which is provided with multiple quick-release lower seats, with the number of quick-release lower seats being L1.

[0008] The detection module includes a connector and multiple brackets mounted on the connector. The multiple brackets are distributed circumferentially along the connector, and the number of brackets is L2, where L1>L2. Each bracket has a quick-release upper seat connected to the end away from the connector, and each quick-release upper seat can be connected to any quick-release lower seat.

[0009] As one possible implementation of the aforementioned flexible inspection fixture, multiple quick-release lower seats are arranged in a matrix.

[0010] As one possible implementation of the aforementioned flexible inspection fixture, the quick-release lower seat includes a lower seat body and a lower seat valve core, with the lower seat valve core being rotatably installed in the lower seat body via a snap ring. The quick-release upper seat includes an upper seat body and an upper seat valve core, with the upper seat valve core installed in the upper seat body and the upper seat valve core being threadedly connected to the lower seat valve core.

[0011] As one possible implementation of the aforementioned flexible inspection fixture, one of the lower and upper seats has a protrusion, and the other of the lower and upper seats has a groove, with the protrusion engaging with the groove.

[0012] As one possible implementation of the aforementioned flexible inspection fixture, the lower valve core is connected to a handle, which extends out of the lower body and can rotate in the first circumferential direction.

[0013] As one possible implementation of the aforementioned flexible inspection fixture, the lower valve core is provided with a limiting pin, and the lower body is provided with a limiting groove extending along the first circumferential direction, with the limiting pin movably disposed within the limiting groove.

[0014] As one possible implementation of the aforementioned flexible inspection fixture, the base plate module also includes an inspection fixture trolley, with the inspection fixture base plate fixedly connected to the top of the inspection fixture trolley.

[0019] This utility model provides a flexible fixture with L1 quick-release lower seats on the fixture base plate and L2 quick-release upper seats for the detection modules, where L1 > L2, ensuring that each quick-release upper seat can quickly connect with any quick-release lower seat. This structure allows a single fixture base plate to adapt to multiple detection module combinations, eliminating the need for custom-made fixture base plates for different detection needs and directly reducing the number of fixture base plates manufactured and the associated costs. Simultaneously, through the flexible switching of quick-release components, multiple detection modules can share the same fixture base plate, significantly reducing the storage space occupied by traditional "one-to-one" fixture configurations, especially in multi-variety, small-batch production scenarios, greatly reducing the fixture's footprint.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figure 1-9 As shown, an embodiment of this utility model provides a flexible inspection fixture, including a base plate module 1 and a detection module 2. The base plate module 1 includes an inspection fixture base plate 11, on which multiple quick-release lower seats 12 are provided, with the number of quick-release lower seats 12 being L1. The detection module 2 includes a connector 21 and multiple brackets 22 mounted on the connector 21. The multiple brackets 22 are distributed circumferentially along the connector 21, with the number of brackets 22 being L2, where L1>L2. Each bracket 22 has a quick-release upper seat 23 connected to its end away from the connector 21, and each quick-release upper seat 23 can be correspondingly connected to any quick-release lower seat 12. Specifically, the connector 21 is an enclosing frame.

[0040] This flexible fixture achieves significant cost and space optimization through modular design. The fixture base plate 11 has L1 quick-release lower seats 12, and the detection module 2 has L2 quick-release upper seats 23, where L1 > L2, ensuring that each quick-release upper seat 23 can quickly connect with any quick-release lower seat 12. This structure allows a single fixture base plate 11 to accommodate multiple combinations of detection modules 2, eliminating the need for custom-made fixture base plates 11 for different detection requirements, directly reducing the number of fixture base plates and investment costs. Simultaneously, through flexible switching of quick-release components, multiple detection modules 2 can share the same fixture base plate 11, significantly reducing the storage space occupied by traditional "one-to-one" fixture configurations, especially in multi-variety, small-batch production scenarios, greatly reducing the fixture's footprint. Furthermore, the modular quick-release design shortens fixture replacement and debugging time, and combined with reusable standard interface components, enables rapid switching between different product fixtures, further reducing long-term maintenance costs and material waste, and significantly lowering production costs.

[0041] Furthermore, multiple quick-release lower brackets 12 are arranged in a matrix. Specifically, the multiple quick-release lower brackets 12 are arranged in a matrix according to a specification of 150mm*150mm, which further improves the flexibility and adaptability of the inspection fixture and the space utilization rate.

[0042] like Figure 1-3 As shown, the matrix layout allows the quick-release lower seat 12 to form a regular coordinate positioning grid. The quick-release upper seat 23 of the detection module 2 can arbitrarily select and connect to the matching quick-release lower seat 12 within the grid according to the detection requirements of different workpieces, without the need to redesign the base plate hole positions, thus realizing the rapid reconfiguration and expansion of the detection module 2. The standardized 150mm spacing balances detection accuracy and adjustment flexibility, meeting the size detection range requirements of most workpieces while avoiding structural redundancy caused by dense layout, allowing a single fixture base plate 11 to be compatible with more types of detection tasks. This standardized matrix design also reduces the machining complexity of the quick-release lower seat 12, reduces the number of base plate openings and machining time, and further reduces manufacturing costs.

[0043] Furthermore, the fixture base plate 11 is provided with a detection reference component 15, which is used to achieve rapid calibration and repeated calibration of the fixture coordinate system through a coordinate measuring machine. Specifically, the detection reference component 15 is a coordinate measuring machine detection reference block.

[0044] The fixture base plate 11 is equipped with a detection reference component 15, which allows for rapid calibration and repeated adjustment of the fixture's coordinate system using a coordinate measuring machine (CMM), significantly improving the stability and long-term reliability of the detection accuracy. The detection reference component 15 serves as the "coordinate origin reference" of the fixture, and its positional accuracy is directly related to the measurement reference of the entire fixture. The CMM can quickly establish a mapping relationship with the product design coordinate system by identifying the precise coordinates of the detection reference component 15 (such as center point, plane, or hole system), achieving one-click calibration of the fixture's coordinate system and greatly saving calibration time.

[0045] It should be noted that the calibration and standardization of the coordinate measuring machine for the coordinate measuring reference block is existing technology, and its working principle will not be elaborated here.

[0046] Furthermore, referring to Figure 4 and Figure 5 The quick-release lower seat 12 includes a lower seat body 121 and a lower seat valve core 122. The lower seat valve core 122 is rotatably installed in the lower seat body 121 via a snap ring 123. The quick-release upper seat 23 includes an upper seat body 231 and an upper seat valve core 232. The upper seat valve core 232 is installed in the upper seat body 231 and is threadedly connected to the lower seat valve core 122.

[0047] The quick-release lower seat 12 and quick-release upper seat 23 are connected by a valve core thread and a retaining spring rotation structure, enabling quick assembly / disassembly and secure locking of the detection module 2. The lower seat valve core 122 is rotatably installed inside the lower seat body 121 via the retaining spring 123. The upper seat valve core 232 is threadedly connected to the lower seat valve core 122. Rotating the upper seat body 231 allows for quick tightening or disassembly, reducing assembly / disassembly time. The elastic limiting effect of the retaining spring 123 ensures stable rotation of the valve core during connection, preventing jamming or misalignment during thread engagement and improving operational smoothness.

[0048] Furthermore, one of the lower seat 121 and the upper seat 231 is provided with a protrusion 233, and the other of the lower seat 121 and the upper seat 231 is provided with a groove 124, with the protrusion 233 engaging with the groove 124. Specifically, the groove 124 is a conical groove, and the protrusion 233 is a conical boss. It should be noted that the shapes of the groove 124 and the protrusion 233 are not specifically limited.

[0049] Reference Figure 6 and Figure 8The lower seat 121 and the upper seat 231 are engaged by the engagement of the protrusion 233 and the groove 124, further improving the positioning accuracy and torsional resistance of the quick-release connection. Based on the threaded connection, the protrusion 233 and the groove 124 form a mechanical anti-rotation structure, effectively limiting the relative circumferential rotation between the upper seat 231 and the lower seat 121, preventing loosening of the threads due to vibration or force during testing, and ensuring the connection stability between the testing module 2 and the base plate module 1. Simultaneously, the guiding effect of the protrusion 233 and the groove 124 allows the threads of the upper valve core 232 and the lower valve core 122 to be quickly aligned, reducing manual alignment time and improving assembly and disassembly efficiency.

[0050] Furthermore, the lower valve core 122 is connected to a handle 125, which extends out of the lower valve body 121 and is able to rotate in the first circumferential direction.

[0051] The handle 125 is connected to the lower valve core 122 and extends out of the lower seat body 121. By rotating the handle 125 in the first circumferential direction, the threads of the upper valve core 232 and the lower valve core 122 can be engaged, which has the advantage of quick fixation. This enables the detection module 2 to be repeatedly and quickly fixed on the base plate module 1, further optimizing the ease of operation and labor-saving of the quick-release connection. The handle 125, as an extension of the lever arm for rotation operation, allows the operator to manually drive the lower valve core 122 to rotate without the aid of tools. Combined with the threaded connection of the upper valve core 232, it enables the quick tightening or loosening of the quick-release upper seat 23 and the quick-release lower seat 12, saving disassembly and assembly time.

[0052] Furthermore, the lower valve core 122 is provided with a limiting pin 126, and the lower body 121 is provided with a limiting groove 127 extending along the first circumferential direction, and the limiting pin 126 is movably disposed in the limiting groove 127.

[0053] Reference Figure 7 The lower valve core 122 is equipped with a limiting pin 126, and the lower seat body 121 is correspondingly equipped with a limiting groove 127. The limiting pin 126 can move within the limiting groove 127 along the first circumferential direction. Through the abutment between the limiting pin 126 and the groove wall of the limiting groove 127, the maximum rotation angle of the lower valve core 122 is strictly limited. This design achieves precise control of the valve core rotation angle and mechanical limit protection. In addition, the cooperation between the limiting pin 126 and the limiting groove 127 can provide feedback on the rotation position of the lower valve core 122. The operator can judge whether the locking or unlocking limit has been reached by the "sticking sensation" when the handle 125 is turned, without relying on visual observation, thus improving the reliability in blind operation scenarios.

[0054] Furthermore, the base plate module 1 also includes a fixture trolley 13, with the fixture base plate 11 fixedly connected to the top of the fixture trolley 13.

[0055] The addition of a fixture trolley 13 to the base plate module 1, with the fixture base plate 11 fixed to its top, significantly improves the flexibility and adaptability of the fixture's movement. The fixture trolley 13 can drive the entire base plate module 1 and the assembled testing module 2 to achieve rapid transfer within the workshop without relying on hoisting equipment. It is especially suitable for dynamic allocation in multi-station testing scenarios, reducing fixture idle time and improving equipment utilization.

[0056] Furthermore, the fixture base plate 11 and the fixture trolley 13 are integrally formed structural components.

[0057] The fixture base plate 11 and fixture carriage 13 adopt an integrated molding structure, further enhancing the overall rigidity and structural stability. The integrated casting or welding process avoids assembly gaps and stress concentrations that may occur with separate connections, ensuring no relative displacement between the fixture base plate 11 and fixture carriage 13 frame during movement and inspection, thus improving the consistency of the inspection benchmark and measurement accuracy. Simultaneously, the integrated structure eliminates connecting parts (such as bolts and locating pins) and assembly processes found in traditional separate designs, reducing the number of parts and machining time, and lowering manufacturing costs.

[0058] Furthermore, the base plate module 1 also includes a collision protection component 14, which is fixedly sleeved on the outside of the inspection trolley 13.

[0059] The base plate module 1 is equipped with a crash protector 14, which is fixedly fitted onto the outside of the fixture carriage 13. This effectively improves the safety and durability of the fixture during movement and use. The crash protector 14 cushions the impact force when the fixture carriage 13 collides with external objects (such as equipment, walls, workpieces, or personnel), preventing damage to the fixture base plate 11, quick-release components, and detection module 2 from direct impact, thus reducing equipment maintenance costs and downtime. Simultaneously, the crash protector 14 forms a physical protective barrier, reducing the risk of injury from accidental contact with the equipment and improving operational safety. Furthermore, the encasing design of the crash protector 14 reduces wear on the outside of the fixture carriage 13, extending its overall service life. Especially during frequent movement or operation in confined spaces, it effectively addresses common scenarios such as bumps and scratches, further enhancing the fixture's environmental adaptability and reliability.

[0060] like Figure 9 As shown, after the testing module 2 is used, it is stored on the inspection fixture storage cart 3. Another set of testing modules 2 for different products is installed and used on the inspection fixture base plate 11. The inspection fixture storage cart 3 enables the rapid storage of testing modules 2 for different products, thereby reducing the manufacturing cost and floor space of the inspection fixture.
