Description

Technical Field

[0001] This application relates to the field of tooling technology, and in particular to a tooling for rapid inspection of parts. Background Technology

[0002] Parts have various functional openings, and accurately controlling the dimensions of these openings (such as inner width, inner diameter, and groove width) is crucial for ensuring the assemblability, functionality, and interchangeability of the parts. Currently, commonly used inspection methods include: 1. General-purpose measuring tools (such as calipers, micrometers, and plug gauges): Inconvenient to operate, difficult to measure, and inefficient for openings that are deep, in narrow spaces, or have irregular contours, especially in mass production where measurement accuracy is easily affected by the operator's skill and experience; 2. Coordinate measuring machine (CMM): High accuracy, but slow inspection speed and high cost, typically used for sampling or first-piece inspection, unsuitable for rapid full inspection on the production line; 3. Custom-made fixtures: While solving efficiency and operability issues, traditional custom-made fixtures are often complex in structure, high in manufacturing cost, and require extremely high part positioning accuracy, sometimes necessitating complex clamping mechanisms.

[0003] In related technologies, hole position detection fixtures are generally used, but they are mainly for hole spacing in the same direction rather than the opening size of the part itself. It is difficult to quickly determine whether the opening size of an integral part is qualified, which causes inconvenience. Therefore, how to improve the ease of use of rapid detection fixtures is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a rapid inspection fixture for parts, which improves ease of use.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, embodiments of this application provide a rapid inspection fixture for a part, the part having a first sidewall and a second sidewall, the first sidewall and the second sidewall being spaced apart to form an opening, the rapid inspection fixture including a first rod portion, a first positioning portion and a second positioning portion; along the length direction of the first rod portion, the first positioning portion and the second positioning portion are respectively disposed on both sides of the first rod portion, the second positioning portion being adapted to be fixed to the second sidewall; wherein, the first positioning portion includes a first positioning block, at least a portion of the first positioning block being located outside the first sidewall and spaced apart from the first sidewall to form a first gap, the first gap being used to determine the numerical change of the opening.

[0006] The rapid inspection fixture for parts proposed in the first aspect of this application does not rely on complex measuring instruments or professional operating skills. By measuring the value of the first gap with simple measuring tools, the expansion and contraction of the part opening can be quickly determined. Compared with traditional inspection methods, it significantly reduces the operating threshold and improves the convenience of inspection. It has a simple structure, is easy to operate, has high inspection efficiency, reliable accuracy, and moderate cost. It can directly read or quickly determine the specific size of the opening of an integrated part or whether it is qualified. At the same time, the second positioning part and the second side wall form a fixed position, and the first positioning block can always be kept in the preset position of the first rod part, avoiding the inspection error caused by positioning offset during the inspection process and ensuring the accuracy of the inspection results.

[0007] Optionally, the first positioning block includes a first connecting part and a first positioning block body. The first connecting part is fixed to one side of the first rod part in its length direction, and the first positioning block body is disposed on the first connecting part and located outside the opening.

[0008] In the above scheme, a connecting part serves to securely connect the first rod and the first positioning block body, while providing a reasonable installation height and position for the first positioning block body, ensuring that it is accurately positioned at the preset position outside the opening. This design ensures higher positioning accuracy. The fixed connection between the first connecting part and the first rod prevents the first positioning block body from shifting or shaking, ensuring its relative position with the first sidewall remains stable. This, in turn, keeps the initial state and changes of the first gap accurate, improving the reliability of the detection results.

[0009] Optionally, the second positioning part includes a second positioning block and a third positioning block, at least a portion of the second positioning block is located on the outer side of the second sidewall, the third positioning block is located on the inner side of the second sidewall, and the third positioning block is movable relative to the second positioning block to selectively clamp the second sidewall.

[0010] In the above scheme, the second positioning block and the third positioning block can be clamped on the inner and outer sides of the second side wall, respectively. The movement of the third positioning block achieves a stable clamping of the second side wall, ensuring that the positioning reference of the tooling and the part does not deviate. This setting can greatly improve the positioning stability. The second positioning block and the third positioning block can form a limit from the inner and outer sides of the second side wall, preventing the tooling from shifting or loosening due to vibration, external force, etc. during the detection process. This provides a stable reference for the accurate detection of the first gap and ensures the reliability of the detection results.

[0011] Optionally, the second positioning part further includes a fixing pin, a fixing frame, and a driving component. The fixing frame is disposed on the first rod part, the fixing pin is slidably disposed on the fixing frame, one side of the fixing pin is connected to the third positioning block, and the other side of the fixing pin is poweredly connected to the driving component.

[0012] In the above scheme, the fixing frame provides a stable mounting base for the fixing pin and the driving component. The fixing pin plays the role of accurately transmitting the driving force. The driving component drives the third positioning block to move smoothly through the fixing pin, realizing controllable clamping and unlocking of the second side wall. This setting can make the positioning accuracy more precise. The sliding cooperation between the fixing pin and the fixing frame forms a guiding constraint, which can limit the movement trajectory of the third positioning block, prevent it from deviating or tilting, and ensure that the third positioning block is accurately aligned with the second positioning block. This ensures the consistency of the positioning reference of the tooling and the part, and improves the reliability of the test results.

[0013] Optionally, the third positioning block is provided with a threaded post, and the fixing pin is provided with a threaded hole. The threaded post is fitted into the threaded hole so that the distance between the third positioning block and the fixing frame is adjustable.

[0014] In the above scheme, the helical engagement of the threaded column and the threaded hole forms a precision adjustment structure. By rotating the third positioning block, the distance between it and the fixed frame can be finely adjusted, thereby accurately controlling the relative position of the third positioning block and the second positioning block. This setting helps to further improve positioning accuracy. At the same time, it can be compatible with second sidewalls of different thicknesses without replacing the third positioning block or the fixing pin, or cope with sidewall thickness fluctuations caused by machining errors of the same part. There is no need to design positioning components separately for each working condition, reducing the supporting cost of inspection tooling.

[0015] Optionally, the rapid testing fixture also includes a first positioning pin, which is disposed on the second positioning block and engages with a corresponding positioning hole on the second side wall.

[0016] In the above scheme, the first locating pin, in conjunction with the locating hole, enables rapid positioning of the fixture and part. Based on the clamping of the second and third locating blocks against the second sidewall, the relative position of the fixture and part is further locked. This design further improves the positioning accuracy of gap detection, avoids reference offset caused by relying solely on clamping force for positioning, makes the initial state of the first gap more stable, and significantly improves the accuracy of detecting changes in opening value.

[0017] Optionally, the first locating pin and the third locating block are positioned opposite each other along the length of the first rod.

[0018] In the above scheme, it is understood that the relative arrangement of the first locating pin and the third locating block ensures that the locating direction of the first locating pin is coaxially aligned with the clamping direction of the third locating block. This further locks the relative position of the tooling and the part, improving the reliability of clamping and fixing. This arrangement avoids minor movement of the part or offset of the tooling due to misalignment of the force direction, helps maintain a stable positioning reference, and significantly improves the reliability of gap detection results.

[0019] Optionally, the second positioning block includes a second connecting part and a second positioning block body. The second connecting part is fixed to the other side of the first rod part in its length direction, and the second positioning block body is disposed on the second connecting part and located on the outside of the second sidewall. The rapid testing fixture also includes a support protrusion, which is located on the side of the second positioning block body facing the second sidewall.

[0020] In the above scheme, the second connecting part provides a stable mounting carrier and a precise position adjustment base for the second positioning block body, ensuring that it forms a symmetrical and coaxial positioning reference with the first positioning part. The support protrusion fits against the second sidewall through surface contact, further improving the stability of fixing the part. This design ensures higher positioning accuracy, as the support protrusion can precisely fit against the actual reference surface of the second sidewall, and together with the first positioning pin, further locks the relative position, significantly improving the consistency of the opening detection reference.

[0021] Optionally, there are multiple support protrusions, which are spaced apart around the first positioning pin.

[0022] In the above scheme, it can be understood that multiple support protrusions form a ring-shaped support structure, which together with the first positioning pin plays a positioning role. As such, the layout of multiple support protrusions surrounding the first positioning pin allows the support points to be evenly distributed around the positioning center, avoiding tool tilting or reference offset caused by single-point support. Combined with the radial constraint of the positioning pin, the consistency of the detection reference is greatly improved.

[0023] Optionally, the rapid testing fixture also includes a second positioning pin, which is disposed on the first positioning block and engages with a corresponding positioning hole on the first sidewall.

[0024] In the above scheme, it can be understood that the precise fit between the second locating pin and the locating hole on the first side wall, together with the first locating pin of the second locating part, forms a double-sided positioning. Positioning constraints are established on the first and second side walls respectively, completely locking the relative position of the tooling and the part. With this configuration, the second locating pins on both sides of the first and second side walls, together with the first locating pin, restrict the translational and rotational deviations of the part in the plane, avoiding tooling tilting or drifting caused by unilateral positioning, and significantly improving the accuracy of opening value change detection.

[0034] Parts have various functional openings, and accurately controlling the dimensions of these openings (such as inner width, inner diameter, and groove width) is crucial for ensuring the assemblability, functionality, and interchangeability of the parts. Currently, commonly used inspection methods include: 1. General-purpose measuring tools (such as calipers, micrometers, and plug gauges): Inconvenient to operate, difficult to measure, and inefficient for openings that are deep, in narrow spaces, or have irregular contours, especially in mass production where measurement accuracy is easily affected by the operator's skill and experience; 2. Coordinate measuring machine (CMM): High accuracy, but slow inspection speed and high cost, typically used for sampling or first-piece inspection, unsuitable for rapid full inspection on the production line; 3. Custom-made fixtures: While solving efficiency and operability issues, traditional custom-made fixtures are often complex in structure, high in manufacturing cost, and require extremely high part positioning accuracy, sometimes necessitating complex clamping mechanisms.

[0035] In related technologies, hole position detection fixtures are generally used, but they are mainly for hole spacing in the same direction rather than the opening size of the part itself. It is difficult to quickly determine whether the opening size of an integral part is qualified, which causes inconvenience. Therefore, how to improve the ease of use of rapid detection fixtures is a technical problem that urgently needs to be solved.

[0036] Therefore, to improve the convenience of inspection, this application provides a rapid inspection fixture 2000 for part 1000. Along the length of the first rod 100, a first positioning part 200 and a second positioning part 300 are respectively disposed on both sides of the first rod 100. The second positioning part 300 is adapted to be fixed to the second sidewall 1002. The first positioning part 200 includes a first positioning block 210, at least a portion of which is located outside the first sidewall 1001 and spaced apart from the first sidewall 1001 to form a first gap A. The first gap A is used for judgment. The change in the value of the opening 1003 can be quickly determined by measuring the value of the first gap A with a simple measuring tool, without relying on complex measuring instruments or professional operating skills. This significantly lowers the operating threshold and improves the convenience of testing compared to traditional testing methods. At the same time, the second positioning part 300 and the second side wall 1002 form a fixed position, and the first positioning block 210 always stays in the preset position of the first rod part 100, avoiding the detection error caused by positioning offset during the testing process and ensuring the accuracy of the test results.

[0037] The following description, in conjunction with the accompanying drawings, describes a rapid inspection fixture 2000 for part 1000 proposed in this application.

[0038] Please refer to Figure 1 and Figure 2According to an embodiment of this application, a rapid inspection fixture 2000 for a part 1000 is provided. The part 1000 has a first sidewall 1001 and a second sidewall 1002. The first sidewall 1001 and the second sidewall 1002 are spaced apart to form an opening 1003. The rapid inspection fixture 2000 includes a first rod portion 100, a first positioning portion 200 and a second positioning portion 300.

[0039] Along the length of the first rod portion 100, the first positioning portion 200 and the second positioning portion 300 are respectively disposed on both sides of the first rod portion 100. The second positioning portion 300 is adapted to be fixed to the second side wall 1002. Specifically, the first positioning portion 200 may be located on one side of the first rod portion 100 along its length, and the second positioning portion 300 may be located on the other side of the first rod portion 100 along its length. The second positioning portion 300 may be selectively clamped or snapped to the second side wall 1002 so that the rapid testing fixture 2000 and the part 1000 are fixed as a whole and cannot move independently. That is to say, the first rod portion 100 can be kept stable by the fixed connection between the second positioning portion 300 and the part 1000.

[0040] Understandably, the second positioning part 300 forms a fixed fit with the second side wall 1002 of the part 1000, providing a precise and stable installation benchmark for the entire testing fixture, avoiding displacement or shaking of the fixture during the testing process, and ensuring the accuracy of the testing results from the source; at the same time, the first positioning part 200 and the second positioning part 300 are located on both sides of the first rod part 100, forming a symmetrical and balanced force structure. After the fixture is assembled, the overall stability is strong, and the testing accuracy is not easily affected by external forces or fluctuations in the state of the part 1000 itself.

[0041] Furthermore, without complicated assembly steps, the installation and fixation between the rapid testing fixture 2000 and the part 1000 can be quickly completed simply by fixing the second positioning part 300 to the second side wall 1002, which greatly shortens the preparation time before testing. No modification or disassembly of the part 1000 is required, and testing can be carried out directly in the original state of the part 1000, avoiding damage to the structure of the part 1000 or affecting its performance.

[0042] In addition, it can be flexibly adapted to the inspection of openings 1003 of parts 1000 of different lengths and specifications. By simply adjusting the length of the first rod 100 or the installation position of the positioning part according to the size of the part 1000, the inspection needs of parts 1000 of various specifications can be met without the need to design special tooling separately, thus reducing inspection costs.

[0043] The first positioning part 200 includes a first positioning block 210. At least a portion of the first positioning block 210 is located outside the first sidewall 1001 and is spaced apart from the first sidewall 1001 to form a first gap A. The first gap A is used to determine the numerical change of the opening 1003. Specifically, the first positioning block 210 is fixedly disposed on one side of the first rod part 100.

[0044] In the above scheme, the numerical change of the opening 1003 of the part 1000 is converted into a change of the gap state by the first gap A formed by the first positioning block 210 and the first side wall 1001. For example, the gap widens to correspond to the expansion of the opening 1003, and the gap narrows to correspond to the contraction of the opening 1003. This facilitates the rapid detection of the change in the opening 1003, reduces the operating threshold, and features a simple structure, convenient operation, high detection efficiency, reliable accuracy, and moderate cost. It can also directly read or quickly determine the specific size or whether the opening 1003 of the integrated part 1000 is qualified.

[0045] In a specific embodiment, the initial state of the first gap A can be preset to a standard value. Subsequently, only the change in gap needs to be compared to quantify the numerical fluctuation of the opening 1003, avoiding subjective judgment errors and ensuring the accuracy of the detection results.

[0046] In the above solution, there is no need to perform multi-dimensional measurements or data conversions on part 1000. Only by observing or simply measuring the change in the first gap A can the numerical change of the opening 1003 be quickly determined. The single inspection takes a short time and is suitable for batch sampling inspection and real-time monitoring on the production line. It can accurately capture minute changes in the opening 1003, which helps to improve production efficiency.

[0047] In other embodiments, please refer to Figure 3 The first positioning block 210 includes a first connecting part 211 and a first positioning block body 212. The first connecting part 211 is fixed to one side of the first rod part 100 in its length direction, and the first positioning block body 212 is disposed on the first connecting part 211 and located outside the opening 1003.

[0048] Understandably, the first connecting part 211 serves to securely connect the first rod part 100 and the first positioning block body 212, while providing a reasonable installation height and position for the first positioning block body 212, ensuring that it is accurately positioned at the preset position outside the opening 1003. This design ensures higher positioning accuracy. The fixed connection between the first connecting part 211 and the first rod part 100 prevents the first positioning block body 212 from shifting or shaking, ensuring a stable relative position between it and the first sidewall 1001. This, in turn, keeps the initial state and changes of the first gap A consistently accurate, improving the reliability of the detection results.

[0049] Meanwhile, it enhances flexibility, facilitating assembly and adjustment. By replacing the first positioning block 210 with different sizes and shapes, it can adapt to the inspection needs of parts 1000 with different opening 1003 specifications and sidewall shapes, without requiring a complete change of tooling, thus reducing inspection costs. Furthermore, its protective properties are further improved. The first positioning block body 212 is mounted on the outside of the opening 1003 via the first connecting part 211, and does not directly contact the first sidewall 1001 of the part 1000 or the inside of the opening 1003. This avoids scratching and squeezing damage to the surface of the part 1000 during inspection, and also prevents impurities inside the opening 1003 of the part 1000 from affecting the tooling positioning, thus balancing inspection functionality and part 1000 protection.

[0050] In addition, the structure is more rigid. The first connecting part 211 can be specifically designed as a reinforced structure to enhance the overall load-bearing capacity and stability of the first positioning block 210, avoid deformation caused by long-term use of the tooling or external force, and extend its service life.

[0051] In other embodiments, please refer to Figure 3 The second positioning part 300 includes a second positioning block 310 and a third positioning block 320. At least a portion of the second positioning block 310 is located on the outer side of the second sidewall 1002, and the third positioning block 320 is located on the inner side of the second sidewall 1002. The third positioning block 320 is movable relative to the second positioning block 310 to selectively clamp the second sidewall 1002.

[0052] Understandably, the second positioning block 310 and the third positioning block 320 can be clamped on the inner and outer sides of the second sidewall 1002, respectively. The movement of the third positioning block 320 achieves a stable clamping of the second sidewall 1002, ensuring that the positioning reference of the tooling and the part 1000 does not shift. This design significantly improves positioning stability. The second positioning block 310 and the third positioning block 320 can form limits from both the inner and outer sides of the second sidewall 1002, preventing the tooling from shifting or loosening due to vibration, external forces, etc., during the testing process. This provides a stable reference for the accurate detection of the first gap A, ensuring the reliability of the test results.

[0053] Simultaneously, it can improve the adaptability of the rapid testing fixture 2000. The movable design of the third positioning block 320 can adjust the clamping distance and force, which can adapt to the second sidewall 1002 with different thicknesses and is also compatible with parts 1000 with slight unevenness on the surface of the second sidewall 1002. There is no need to design a separate positioning structure for each specification of part 1000, which improves the versatility of the fixture. It makes the operation convenient and efficient. Just move the third positioning block 320 to complete the clamping or unlocking. There is no need for complicated bolt tightening or disassembly process, which can quickly realize the assembly and separation of the fixture and the part 1000, shorten the test preparation time, and facilitate rapid mass testing.

[0054] In addition, the second positioning block 310 and the third positioning block 320 clamp the second side wall 1002 from both the inner and outer sides, making the second side wall 1002 more evenly stressed. This avoids deformation of the side wall of the part 1000 caused by clamping on one side. At the same time, the contact between the positioning block and the part 1000 can reduce the pressure by designing the fitting surface, preventing scratches and damage to the surface of the part 1000, thus balancing positioning accuracy and protection of the part 1000.

[0055] In other embodiments, please refer to Figure 3 The second positioning part 300 also includes a fixing pin 330, a fixing frame 340 and a driving member 350. The fixing frame 340 is disposed on the first rod part 100, and the fixing pin 330 is slidably disposed on the fixing frame 340. One side of the fixing pin 330 is connected to the third positioning block 320, and the other side of the fixing pin 330 is poweredly connected to the driving member 350.

[0056] Understandably, the fixing frame 340 provides a stable mounting base for the fixing pin 330 and the driving component 350. The fixing pin 330 plays a role in accurately transmitting driving force, and the driving component 350 drives the third positioning block 320 to move smoothly through the fixing pin 330, realizing controllable clamping and unlocking of the second side wall 1002. This configuration allows for more precise positioning. The sliding cooperation between the fixing pin 330 and the fixing frame 340 forms a guiding constraint, which can limit the movement trajectory of the third positioning block 320, prevent its deviation or tilting, and ensure that the third positioning block 320 is accurately aligned with the second positioning block 310. This, in turn, ensures the consistency of the positioning reference between the tooling and the part 1000, and improves the reliability of the test results.

[0057] Meanwhile, the operation is more labor-saving and efficient. The driving component 350 (such as a manual knob, pneumatic cylinder, etc.) replaces the manual pushing of the third positioning block 320, which greatly reduces the intensity of operation. The driving force output is stable and can quickly complete the clamping and unlocking actions, shorten the tooling assembly time. Moreover, the clamping force is controllable and adjustable. By adjusting the output force of the driving component 350 (such as adjusting the air pressure and rotation stroke), the clamping force of the third positioning block 320 can be precisely controlled, which can ensure stable clamping and avoid deformation of the side wall of part 1000 due to excessive clamping force. It is easy to adapt to the inspection needs of parts 1000 with different materials and thicknesses.

[0058] In addition, the structure is more stable. The fixed connection between the fixed bracket 340 and the first rod 100 strengthens the overall rigidity of the second positioning part 300. The sliding structure of the fixed pin 330 has less wear and is not easy to jam. It can maintain stable transmission accuracy even after long-term use, which helps to extend the service life.

[0059] In other embodiments, please refer to Figure 3 and Figure 4The third positioning block 320 is provided with a threaded post 321, and the fixing pin 330 has a threaded hole 331. The threaded post 321 fits into the threaded hole 331 to make the distance between the third positioning block 320 and the fixing frame 340 adjustable. It can be understood that the helical fit between the threaded post 321 and the threaded hole 331 forms a precision adjustment structure. By rotating the third positioning block 320, its distance from the fixing frame 340 can be finely adjusted, thereby precisely controlling the relative position of the third positioning block 320 and the second positioning block 310. This design helps to further improve positioning accuracy. The uniform and controllable pitch of the threaded drive helps to ensure precise alignment between the third positioning block 320 and the second positioning block 310, facilitating the clamping and fixing of the second sidewall 1002 with different thicknesses and precision requirements, making the tooling positioning reference more accurate, and improving the reliability of the test results.

[0060] Meanwhile, thanks to its adjustable distance design, it can accommodate second sidewalls 1002 of different thicknesses without replacing the third positioning block 320 or the fixing pin 330, or address sidewall thickness fluctuations in the same part 1000 caused by machining errors. This eliminates the need to design separate positioning components for each working condition, reducing the cost of the inspection tooling. Furthermore, once adjusted, no additional locking structure is required to prevent the third positioning block 320 from shifting due to vibration or external forces, ensuring long-term stability of the clamping state between the tooling and the part 1000.

[0061] In other embodiments, please refer to Figure 3 The rapid inspection fixture 2000 also includes a first positioning pin 400, which is disposed on the second positioning block 310 and engages with a corresponding positioning hole on the second side wall 1002. It can be understood that the engagement of the first positioning pin 400 with the positioning hole enables the rapid inspection fixture 2000 to be positioned relative to the part 1000. Based on the clamping of the second side wall 1002 by the second positioning block 310 and the third positioning block 320, the relative position of the fixture and the part 1000 is further locked. This configuration further improves the positioning accuracy of gap detection, avoids reference offset caused by positioning solely with clamping force, makes the initial state of the first gap A more stable, and significantly improves the accuracy of detecting changes in the opening 1003 value.

[0062] Meanwhile, the assembly efficiency is higher. The guiding effect of the first positioning pin 400 can guide the second positioning block 310 to quickly align with the positioning hole of the part 1000 without repeatedly adjusting the tooling position, shortening the assembly alignment time between the rapid testing tooling 2000 and the part 1000, and improving the clamping stability. It can effectively resist vibration and external force interference during the testing process, prevent relative displacement between the tooling and the part 1000, and ensure the stability and reliability of the testing process.

[0063] In other embodiments, the first locating pin 400 and the third locating block 320 are arranged opposite to each other along the length of the first rod portion 100. It is understood that the opposite arrangement of the first locating pin 400 and the third locating block 320 aligns the locating direction of the first locating pin 400 with the clamping direction of the third locating block 320, further locking the relative position of the tooling and the part 1000 and improving the reliability of clamping and fixing. This arrangement avoids slight movement of the part 1000 or tooling offset caused by misalignment of force direction, helps maintain a stable positioning reference, and significantly improves the reliability of gap detection results.

[0064] Simultaneously, the third positioning block 320 can be guided to automatically align with the positioning direction of the first positioning pin 400 during clamping, eliminating the need for additional clamping angle adjustments. Combined with the guiding effect of the positioning pin, this further shortens the tooling assembly and calibration time, improves clamping stability, and prevents deformation of part 1000 caused by unilateral force or force deviation. Furthermore, it enhances the tooling's resistance to vibration and external interference, ensuring that the reference datum remains stable during testing. This strictly limits the relative displacement between the tooling and part 1000, ensuring that changes in the first gap A accurately reflect the numerical fluctuations of the opening 1003 of part 1000, avoiding testing errors caused by reference datum drift, and further improving the reliability of the testing results.

[0065] In other embodiments, please refer to Figure 3 The second positioning block 310 includes a second connecting part 311 and a second positioning block body 312. The second connecting part 311 is fixed to the other side of the first rod part 100 in its length direction, and the second positioning block body 312 is disposed on the second connecting part 311 and located on the outside of the second side wall 1002. The rapid testing fixture 2000 also includes a support protrusion 500, which is located on the side of the second positioning block body 312 facing the second sidewall 1002.

[0066] Understandably, the second connecting part 311 provides a stable mounting carrier and a precise position adjustment base for the second positioning block body 312, ensuring that it forms a symmetrical and coaxial positioning reference with the first positioning part 200. The support protrusion 500 fits against the second side wall 1002 through surface contact, further improving the stability of fixing with the part 1000. With this configuration, the positioning accuracy is more guaranteed, and the support protrusion 500 can precisely fit against the actual reference surface of the second side wall 1002. Together with the first positioning pin 400, it further locks the relative position, greatly improving the reference consistency of the opening 1003 detection.

[0067] At the same time, it is convenient to clamp the second sidewall 1002 of different thicknesses by replacing the second positioning block 310 of different sizes or adjusting its connection position with the first rod 100. The structure supporting the protrusion 500 can also be compatible with parts 1000 with slightly curved or uneven sidewalls, and can meet diverse testing needs without replacing the entire tooling.

[0068] In other embodiments, please refer to Figure 2 and Figure 4 There are multiple support protrusions 500, which are spaced apart around the first positioning pin 400. It can be understood that the multiple support protrusions 500 form a surrounding support structure, working together with the first positioning pin 400 to perform a positioning function. This arrangement ensures that the support points are evenly distributed around the positioning center, avoiding tooling tilting or reference offset caused by single-point support. Combined with the radial constraint of the positioning pin, this significantly improves the consistency of the detection reference.

[0069] In other embodiments, please refer to Figure 3 The rapid detection fixture 2000 also includes a second positioning pin 600, which is disposed on the first positioning block 210 and engages with a corresponding positioning hole on the first sidewall 1001. It can be understood that the precise engagement of the second positioning pin 600 with the positioning hole on the first sidewall 1001, together with the first positioning pin 400 of the second positioning part 300, forms a double-sided positioning, establishing positioning constraints on the first sidewall 1001 and the second sidewall 1002 respectively, completely locking the relative position of the fixture and the part 1000. Thus, the second positioning pins 600 and the first positioning pins 400 on both sides of the first sidewall 1001 and the second sidewall 1002 jointly restrict the translation and rotation deviation of the part 1000 in the plane, avoiding fixture tilting or drifting caused by unilateral positioning, and significantly improving the accuracy of detecting changes in the opening 1003.

[0070] Meanwhile, the assembly efficiency is higher. The guiding effect of the second positioning pin 600 can guide the first positioning block 210 to quickly align with the positioning hole of the first side wall 1001. In conjunction with the first positioning pin 400 of the second side wall 1002, the tooling and part 1000 can be quickly and accurately aligned without repeated adjustments, thus shortening the preparation time for testing.
