Abstract
Description
Technical Field
[0001] The utility model relates to the field of product testing, in particular to a testing tool. Background Art
[0002] Rivets are fasteners used to connect two or more metal parts. They are fixed together through a riveting process. Rivets are widely used, especially in fields that require high-strength and durable connections, such as aviation, automotive manufacturing, building structures, and shipbuilding.
[0003] During the rivet manufacturing process, finished product inspection is a crucial step. Typically, tools such as calipers or feeler gauges are used to check the form tolerances of the rivet head or shank. However, when using these tools, the operator's skill level, experience, and subjective judgment can affect the accuracy of the measurement results. Furthermore, manual measurement is not only time-consuming and labor-intensive, but also inefficient in large-scale production, potentially failing to meet production speed requirements. Utility Model Content
[0004] The technical problem to be solved by the present invention is to solve at least one of the above-mentioned technical problems.
[0005] The solution of the utility model to solve the technical problem is as follows: a first detection groove and a second detection groove are provided on the inspection tool body, the width of the first detection groove is larger than the width of the second detection groove, the first detection groove allows the qualified rivet head to pass through, and the second detection groove prevents the qualified rivet head from passing through; the inspection tool body is also provided with a first detection hole and a second detection hole, the diameter of the first detection hole is larger than the diameter of the second detection hole, the first detection hole allows the qualified rivet rod to pass through, and the second detection hole prevents the qualified rivet rod from passing through.
[0006] The beneficial effects of this utility model are: through this design, each part of the rivet can be inspected quickly and accurately, ensuring that its quality meets the requirements. By using this inspection fixture, the efficiency and accuracy of rivet inspection can be significantly improved. The operator no longer needs to rely on individual technical skills and subjective judgment, ensuring that each measurement is carried out according to a unified standard. In addition, the use of this inspection fixture greatly reduces the time and labor required for manual measurement, making inspection work in large-scale production more efficient.
[0007] As a further improvement of the above technical solution, the first detection slot and the second detection slot are respectively arranged at the upper and lower ends of the gauge body, and the first detection hole and the second detection hole are arranged in the middle of the gauge body.
[0008] As a further improvement to the above technical solution, this layout helps achieve comprehensiveness and accuracy in the testing process, allowing for more balanced coverage of key product areas, reducing blind spots and improving test reliability. This rational layout makes testing more convenient for staff, reducing operational difficulty and error rates.
[0009] As a further improvement of the above technical solution, the first detection groove and the second detection groove are T-shaped, forming a horizontal channel and a vertical channel. The vertical channel is connected to the edge of the inspection tool body and connects the horizontal channel with the external space. The first detection groove and the second detection groove run through the thickness of the inspection tool body.
[0010] A further improvement to the above technical solution is the inclusion of a notch for inspection throughout the gauge body. This notch enables the gauge to accurately measure and assess the size and shape of rivets. To improve inspection efficiency, these gauges can be placed at specific locations along the production line. This allows for rapid and efficient inspection of rivets in large quantities during the production process. This in-line inspection method not only increases inspection speed but also ensures consistency and accuracy, thereby improving overall production efficiency and product quality.
[0011] As a further improvement of the above technical solution, the first detection hole and the second detection hole are through holes, and the inspection tool body is provided with a sink concentric with the through holes, and the diameter of the sink is larger than the diameter of the rivet head to be inspected.
[0012] As a further improvement to the above technical solution, the beneficial effect is that when the rivet shank completely passes through the through hole of the first detection hole, the rivet head will contact and overlap with the sinking platform. If the rivet head and the sinking platform completely overlap, then we can judge that the concentricity of the rivet head and the rivet shank is qualified. On the contrary, if the rivet head and the sinking platform cannot completely overlap, then it means that there is a problem with the concentricity of the rivet head and the rivet shank, that is, it is unqualified. In this way, not only the accuracy of the detection is improved, but also the detection process is simplified, allowing the operator to quickly and intuitively judge whether the concentricity of the rivet meets the standard.
[0013] As a further improvement of the above technical solution, multiple first detection slots are set, and multiple second detection slots are set, the first detection slots and the second detection slots correspond one to one, all the first detection slots are set at the upper end of the inspection tool body, and all the second detection slots are set at the lower end of the inspection tool body.
[0014] As a further improvement of the above technical solution, the beneficial effect is that by setting multiple detection areas, the inspection tool body can adapt to detection objects of different types and sizes, thereby expanding its scope of application and enabling it to meet more diverse detection needs.
[0015] As a further improvement of the above technical solution, among all the first detection grooves, the width of the first detection groove gradually increases along the direction of the upper end edge line of the gauge body; correspondingly, the width of the second detection groove gradually increases along the direction of the lower end edge line of the gauge body.
[0016] A further improvement to the above technical solution is the gradual increase in width, which allows the gauge to adapt to workpieces of varying sizes, increasing its versatility and flexibility while reducing the need to switch between gauges of varying specifications. As the width of the inspection slot gradually increases, the optimal contact point can be found more quickly during inspection, improving inspection efficiency and shortening production cycles. By reducing the number of gauge changes required, production costs can be reduced, improving economic efficiency.
[0017] As a further improvement of the above technical solution, a plurality of first detection holes are provided, and a plurality of second detection holes are provided, and the first detection holes and the second detection holes correspond to each other one by one.
[0018] As a further improvement of the above technical solution, the beneficial effect is that by setting multiple detection areas, the inspection tool body can adapt to detection objects of different types and sizes, thereby expanding its scope of application and enabling it to meet more diverse detection needs.
[0019] As a further improvement of the above technical solution, among all the first detection holes, the diameter of the first detection holes gradually increases along the direction of the extension of the upper end edge of the gauge body; correspondingly, the diameter of the second detection holes gradually increases along the direction of the extension of the lower end edge of the gauge body.
[0020] A further improvement to the above technical solution is the gradual increase in diameter, which allows the gauge to adapt to workpieces of varying sizes, increasing its versatility and flexibility while reducing the need to switch gauges of varying specifications. Because the diameter of the inspection hole gradually increases, the optimal contact point can be found more quickly during inspection, improving inspection efficiency and shortening production cycles. By reducing the number of gauge changes required, production costs can be reduced, improving economic efficiency.
[0021] As a further improvement of the above technical solution, a positioning hole is provided on the inspection tool body.
[0022] A further improvement to the above technical solution is that the positioning holes effectively secure the position of the gauge, reducing inspection errors caused by gauge movement or offset. The positioning holes also enhance the versatility of the gauge. By adjusting the positioning holes to accommodate different workpieces, the same gauge can be used to inspect a wide variety of workpieces, significantly increasing its usability and economic benefits.
[0023] As a further improvement of the above technical solution, two positioning holes are provided, the two positioning holes are spaced apart, and the depth directions of the two positioning holes intersect, are parallel, or are in different planes.
[0024] As a further improvement to the above technical solution, the provision of two positioning holes and adjustment of the spacing between them significantly improves positioning accuracy and reliability. This dual-positioning hole design better secures and supports related components, reducing displacement caused by vibration or external forces, thereby ensuring stable operation of the equipment or structure.

[0029] Rivets are fasteners used to connect two or more metal parts. They are fixed together through a riveting process. Rivets are widely used, especially in fields that require high-strength and durable connections, such as aviation, automotive manufacturing, building structures, and shipbuilding.
[0030] During the rivet manufacturing process, finished product inspection is a crucial step. Typically, tools such as calipers or feeler gauges are used to check the form tolerances of the rivet head or shank. However, when using these tools, the operator's skill level, experience, and subjective judgment can affect the accuracy of the measurement results. Furthermore, manual measurement is not only time-consuming and labor-intensive, but also inefficient in large-scale production, potentially failing to meet production speed requirements.
[0031] To this end, a checking tool, referring to Figure 1 The device comprises a gauge body 1, characterized in that the gauge body 1 is provided with a first inspection slot 2 and a second inspection slot 3, wherein the width of the first inspection slot 2 is larger than the width of the second inspection slot 3, the first inspection slot 2 allows the qualified rivet head to pass through, and the second inspection slot 3 prevents the qualified rivet head from passing through; the gauge body 1 is also provided with a first inspection hole 4 and a second inspection hole 5, the diameter of the first inspection hole 4 is larger than the diameter of the second inspection hole 5, the first inspection hole 4 allows the qualified rivet shank to pass through, and the second inspection hole 5 prevents the qualified rivet shank from passing through. This design allows for quick and accurate inspection of each part of the rivet to ensure that its quality meets the requirements. By using this gauge, the efficiency and accuracy of rivet inspection can be significantly improved. Operators no longer need to rely on their personal technical level and subjective judgment, ensuring that each measurement is performed according to a unified standard. In addition, the use of this gauge greatly reduces the time and labor required for manual measurement, making inspection work in mass production more efficient.
[0032] In order to improve the efficiency and accuracy of detection and simplify the operation process at the same time. Therefore, in one embodiment, the first detection slot 2 and the second detection slot 3 are respectively arranged at the upper and lower ends of the inspection tool body 1, and the first detection hole 4 and the second detection hole 5 are arranged in the middle of the inspection tool body 1. Such a layout helps to achieve the comprehensiveness and accuracy of the detection process, so that the key parts of the product can be covered more evenly during the detection process, reducing the detection blind spots and improving the reliability of the detection. The reasonable layout enables staff to operate more conveniently when conducting detection, reducing the difficulty of operation and the error rate.
[0033] In the process of rivet detection, it is first necessary to carefully compare and analyze the rivets to be detected with the specially designed inspection tool. Therefore, in one embodiment, the first inspection slot 2 and the second inspection slot 3 are T-shaped, forming a transverse channel 6 and a vertical channel 7, and the vertical channel 7 is connected to the edge of the inspection tool body 1, connecting the transverse channel 6 with the external space, and the first inspection slot 2 and the second inspection slot 3 pass through the thickness of the inspection tool body 1. A notch for detection is passed through the inspection tool body 1. The design of this detection slot enables the inspection tool to effectively measure and evaluate the size and shape of the rivet. In order to improve the detection efficiency, these inspection tools can be set at specific positions on the production line. In this way, rivets can be quickly and efficiently inspected in large quantities during the production process. This assembly line detection method not only improves the detection speed, but also ensures the consistency and accuracy of the detection, thereby improving the overall production efficiency and product quality.
[0034] During the installation process, the rivet head and the rivet rod must ensure that their positions are completely on the same center line to ensure the accuracy and firmness of the riveting. Therefore, in one embodiment, the first detection hole 4 and the second detection hole 5 are through holes 8, and the inspection tool body 1 is provided with a sink 9 concentric with the through hole 8, and the diameter of the sink 9 is larger than the diameter of the rivet head to be tested. When the rivet rod completely passes through the through hole 8 of the first detection hole 4, the rivet head will contact and overlap with the sink 9. If the rivet head and the sink 9 completely overlap, then we can judge that the concentricity of the rivet head and the rivet rod is qualified. On the contrary, if the rivet head and the sink 9 cannot completely overlap, then it means that there is a problem with the concentricity of the rivet head and the rivet rod, that is, it is unqualified. In this way, not only the accuracy of the detection is improved, but also the detection process is simplified, so that the operator can quickly and intuitively judge whether the concentricity of the rivet meets the standard.
[0035] In the production process, a variety of rivets of different specifications are usually involved. These rivets may differ in size, shape or material to meet various application requirements. Therefore, in one embodiment, a plurality of first detection slots 2 are provided, and a plurality of second detection slots 3 are provided, and the first detection slots 2 and the second detection slots 3 correspond one to one, and all the first detection slots 2 are provided at the upper end of the gauge body 1, and all the second detection slots 3 are provided at the lower end of the gauge body 1. By setting multiple detection areas, the gauge body 1 can adapt to detection objects of different types and sizes, thereby expanding its scope of application and enabling it to meet more diverse detection needs.
[0036] If the inspection tool is replaced frequently, it will have a negative impact on work efficiency. Therefore, in one embodiment, among all the first inspection slots 2, the width of the first inspection slot 2 gradually increases along the direction of the upper end edge line of the inspection tool body 1; correspondingly, the width of the second inspection slot 3 gradually increases along the direction of the lower end edge line of the inspection tool body 1. The gradually increasing width design enables the inspection tool to adapt to workpieces of different sizes, improves the versatility and flexibility of the inspection tool, and reduces the need to replace inspection tools of different specifications. Since the width of the inspection slot gradually increases, the optimal contact point can be found more quickly during the inspection process, thereby improving inspection efficiency and shortening the production cycle. By reducing the number of times inspection tools of different specifications are replaced, the cost in the production process can be reduced and the economic benefits can be improved.
[0037] The production process typically involves the use of a variety of rivets of varying specifications. These rivets may vary in size, shape, or material to meet a variety of application requirements. Therefore, in one embodiment, multiple first detection holes 4 and multiple second detection holes 5 are provided, with each first detection hole 4 corresponding to each second detection hole 5. By providing multiple detection areas, the inspection tool body 1 can adapt to inspection objects of different types and sizes, thereby expanding its scope of application and enabling it to meet a wider range of inspection needs.
[0038] If the gauge is replaced frequently, it will have a negative impact on work efficiency. Therefore, in one embodiment, among all the first detection holes 4, the diameter of the first detection hole 4 gradually increases along the direction of the extension of the upper end edge line of the gauge body 1; correspondingly, the diameter of the second detection hole 5 gradually increases along the direction of the extension of the lower end edge line of the gauge body 1. The gradually increasing diameter design enables the gauge to adapt to workpieces of different sizes, improves the versatility and flexibility of the gauge, and reduces the need to replace gauges of different specifications. Since the diameter of the detection groove gradually increases, the optimal contact point can be found more quickly during the detection process, thereby improving detection efficiency and shortening the production cycle. By reducing the number of times that gauges of different specifications are replaced, the cost in the production process can be reduced and the economic benefits can be improved.
[0039] During the use of the inspection tool, detection errors may occur due to offset. Therefore, in one embodiment, the inspection tool body 1 is further provided with a positioning hole 10. The positioning hole 10 can effectively fix the position of the inspection tool, reducing detection errors caused by movement or offset of the inspection tool. The positioning hole 10 also enhances the versatility of the inspection tool. Different workpieces can be adapted by adjusting the position of the positioning hole 10, so that the same set of inspection tools can be used to inspect a variety of workpieces, greatly improving the use value and economic benefits of the inspection tool.
[0040] The design of the double positioning holes 10 can better resist interference from external factors, such as vibration, impact, etc., and ensure that the components can be stably maintained in the predetermined position. Therefore, in one embodiment, two positioning holes 10 are provided, and the two positioning holes 10 are spaced apart, and the depth directions of the two positioning holes 10 intersect, are parallel, or are skewed. By providing two positioning holes 10 and adjusting the spacing between them, the accuracy and reliability of positioning can be significantly improved. This design of double positioning holes 10 can better fix and support related components, reduce displacement caused by vibration or external force, and thus ensure the stable operation of the equipment or structure.
[0041] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
