Abstract
Description
Technical Field
[0001] This application relates to the technical field of automotive parts inspection, and in particular to an automotive stamping parts inspection device. Background Technology
[0002] Automotive stamping parts are automotive components manufactured through sheet metal stamping processes. They are widely used in various fields such as body panels, structural reinforcements, engine system components, and chassis parts.
[0003] Stamping is a process in which a hydraulic system pushes a die to contact a sheet metal, applying forces in different directions to different parts of the sheet metal. This causes the sheet metal to deform under stress, producing a specified shape. At the same time, holes are made at designated locations on the stamped part for mounting and mating with other components. During the production of automotive stamped parts, while the sheet metal deforms under stress, lateral forces may cause the sheet metal to shift on the die, resulting in dimensional deviations in the stamped part and rendering it unusable. Currently, manufacturers use inspection devices to check the contour and hole positions of stamped parts before they leave the factory to prevent defective products from being shipped.
[0004] Because automotive stamping parts come in a variety of shapes, conventional testing equipment is not well-suited for irregularly shaped stamping parts, leading to decreased testing accuracy and potentially allowing defective products to pass through the inspection process. Utility Model Content
[0005] To address the problem that conventional testing devices are not well-suited for irregularly shaped stamped parts, leading to decreased testing accuracy, this application provides an automotive stamped part testing device.
[0006] This application provides an automotive stamping parts testing device, which adopts the following technical solution: An automotive stamping part inspection device includes a worktable, a base for placing the stamping part, and an inspection component for inspecting the outline and hole positions of the stamping part. The base is detachably mounted on the worktable; the surface outline of the base is adapted to the outline of the stamping part; the inspection component is placed on the worktable and is retrieved when ready for inspection.
[0007] By adopting the above technical solution, during the inspection, a suitable base is first selected according to the shape of the stamped part and installed on the bearing platform. The stamped part is then placed on the base, and the stamped part is accurately positioned by utilizing the contour adaptability of the base. Then, the outline and hole positions of the stamped part are inspected by the inspection components. The base can be detachably installed on the worktable, which allows the device to adapt to stamped parts of various shapes and sizes by changing different bases, thus solving the problem of insufficient adaptability of conventional inspection devices to irregularly shaped stamped parts.
[0008] Preferably, the workbench is provided with a snap-fit hole, and the base is provided with a protrusion that snaps into the snap-fit hole.
[0009] By adopting the above technical solution, the snap-fit hole on the workbench and the protrusion on the base form a snap-fit engagement. This connection method is simple and reliable, and can quickly realize the installation and disassembly of the base, thereby improving the efficiency of replacing different bases to adapt to different stamping parts.
[0010] Preferably, the detection component includes a pin, and the base has mounting holes corresponding to the hole positions and diameter of the stamped part. The pin passes through the hole of the stamped part and is inserted into the mounting hole to detect whether the hole position of the stamped part is qualified. The number of mounting holes corresponds to the number of stamped parts, and there are multiple pins.
[0011] By adopting the above technical solution, the pin passes through the hole in the stamped part and is inserted into the mounting hole on the base, which allows for a direct assessment of whether the hole position is qualified: if the pin can be inserted smoothly, it indicates that the position and diameter of the hole meet the requirements; if it cannot be inserted, it is unqualified; the diameters of multiple pins are matched with the diameters of holes on different stamped parts, and the diameter of the mounting hole on the base is consistent with the diameter of the corresponding hole in the stamped part, ensuring targeted testing of hole positions of different sizes, preventing misjudgments caused by mismatched pin sizes, and further improving the adaptability of the device to stamped parts with different hole position specifications.
[0012] Preferably, the detection component further includes a go / no-go gauge. There is a gap between the base and the stamped part. If the go gauge of the go / no-go gauge can pass through the gap between the stamped part and the base, and the no-go gauge of the go / no-go gauge cannot pass through the gap, it indicates that the profile of the stamped part is qualified.
[0013] By adopting the above technical solution, the go / no-go gauge consists of two parts: a go gauge and a no-go gauge. The cross-sectional dimensions of the two parts correspond to the allowable error range of the stamped part's profile: the maximum size of the go gauge equals the maximum allowable clearance of the stamped part, and the minimum size of the no-go gauge equals the minimum allowable clearance of the stamped part. Only when the go gauge can pass through the clearance and the no-go gauge cannot pass through the clearance can the stamped part be judged to have acceptable profile. This method transforms the abstract profile requirement into concrete physical dimensional verification, eliminating the subjectivity of manual visual judgment and ensuring consistency in judgment standards among different inspectors.
[0014] Preferably, the workbench is provided with a pin holder for placing pins, the pin holder has a fixing hole, the axis of the fixing hole is perpendicular to the workbench, and the pin is engaged with the fixing hole; multiple placement racks are provided, and multiple placement racks are engaged with multiple pins respectively.
[0015] By adopting the above technical solution, when not in use, multiple pins can be inserted into multiple storage racks to prevent them from being lost. When in use, operators can easily retrieve the pins, saving time searching for them and facilitating operation. Multiple storage racks are connected to multiple pins, enabling the classified storage of pins of different sizes. This allows testing personnel to quickly find the corresponding pin, reducing the time spent searching for pins and improving the efficiency of pre-test preparation. The design of the fixing hole axis being perpendicular to the worktable ensures that the pin remains vertical after insertion, preventing the pin from tilting or falling over, further protecting the pin's accuracy. At the same time, it keeps the pins on the pin rack neatly arranged, facilitating management and retrieval.
[0016] Preferably, the workbench is also provided with a storage box for storing go / no-go gauges.
[0017] By adopting the above technical solution, after the test is completed, the go / no-go gauge can be placed in the storage box to prevent it from being scattered and lost, ensuring that it is always available during the test, while reducing the time spent searching for tools before the test and optimizing the test process.
[0018] Preferably, the base is provided with a guide post, the end of the guide post is threaded, and the guide post is screwed onto the base in a threaded fit with the mounting hole; multiple guide posts are provided, and the multiple guide posts are screwed into several mounting holes on the base respectively.
[0019] By adopting the above technical solution, the guide post is screwed onto the base via threads, facilitating the installation and replacement of the guide post. This ensures the guide post diameter matches the diameter of the hole on the stamped part, preventing the stamped part from being unable to be installed on the base due to an oversized guide post. During stamped part installation, the guide post can be inserted into the hole of the stamped part first, providing guidance for placement and helping inspection personnel quickly position the stamped part correctly on the base. This reduces adjustment time caused by stamped part placement deviations and improves pre-inspection preparation efficiency. Simultaneously, the guide post can detect whether the hole position on the stamped part is qualified. If the stamped part fits the guide post on the base, it is qualified; otherwise, it is unqualified. The guide post replaces the function of a pin, eliminating the need for a pin holder, simplifying the device structure and reducing manufacturing costs.
[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. During inspection, first select a suitable base according to the shape of the stamped part and install it on the bearing table. Place the stamped part on the base and use the contour adaptability of the base to accurately position the stamped part. Then, use the inspection components to inspect the contour and hole position of the stamped part. The base can be detached and installed on the worktable, which allows the device to adapt to stamped parts of various shapes and sizes by changing different bases, solving the problem of insufficient adaptability of conventional inspection devices to irregularly shaped stamped parts. 2. The plug can be inserted through the hole of the stamping part and into the mounting hole on the base, enabling an intuitive judgment of whether the hole position is qualified: If the plug can be smoothly inserted, it indicates that the position and diameter of the hole meet the requirements; if it cannot be inserted, it is unqualified. The diameters of multiple plugs match the diameters of the holes on different stamping parts respectively, and the diameter of the mounting hole on the base is the same as that of the corresponding hole on the stamping part, ensuring targeted detection of hole positions of different sizes, preventing misjudgment caused by unmatched plug sizes, and further improving the adaptability of the device to stamping parts with different hole position specifications. The go-no-go gauge consists of a go gauge and a no-go gauge, and the cross-sectional dimensions of both correspond to the allowable error range of the profile tolerance of the stamping part: The maximum size of the go gauge is equal to the maximum allowable clearance of the stamping part, and the minimum size of the no-go gauge is equal to the minimum allowable clearance of the stamping part. Only when the go gauge can pass through the clearance and the no-go gauge cannot pass through the clearance can it be determined that the profile tolerance of the stamping part is qualified. This method converts the abstract profile tolerance requirements into specific physical dimension verification, eliminating the subjectivity of manual visual judgment and ensuring consistent judgment criteria for different inspectors. 3. The guide post is screwed onto the base through threads, facilitating the installation and replacement of the guide post, making the diameter size of the guide post fit the diameter of the hole on the stamping part, and preventing the stamping part from being unable to be installed and placed on the base due to an oversized guide post. When installing the stamping part, the guide post can be first inserted into the hole of the stamping part to provide a guiding function for placing the stamping part, helping the inspector quickly position the stamping part to the correct position on the base, reducing the adjustment time caused by the placement deviation of the stamping part, and improving the preparation efficiency before detection. At the same time, the guide post can detect whether the hole position on the stamping part is qualified. If the stamping part can fit with the guide post on the base, the stamping part is qualified; otherwise, it is unqualified. The guide post replaces the function of the plug, and accordingly, there is no need to set up a plug holder, making the device structure simple and reducing the manufacturing cost.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.
[0024] This application discloses an automotive stamping parts inspection device.
[0025] Example 1: refer to Figure 1 An automotive stamping part inspection device includes a worktable 1, a base 2 for placing a stamping part 10, and an inspection assembly 3 for inspecting the contour and hole positions of the stamping part 10; Reference Figure 2 and Figure 3 The workbench 1 has a snap-fit hole 4, and the base 2 has an integrally formed protrusion 5 that snaps into the snap-fit hole 4; the base 2 is fixed to the workbench 1 by inserting the protrusion 5 into the snap-fit hole 4; the surface contour of the base 2 is adapted to the contour of the stamping part 10; the detection component 3 is placed on the workbench 1 and is used to detect the stamping part 10 when it is ready for inspection.
[0026] During testing, the appropriate base 2 is first selected according to the shape of the stamped part 10 and installed on the support table. The stamped part 10 is then placed on the base 2, and the stamped part 10 is accurately positioned by utilizing the contour adaptability of the base 2. Then, the contour and hole positions of the stamped part 10 are tested by the testing component 3. The base 2 can be detachably installed on the worktable 1, which allows the device to adapt to stamped parts 10 of various shapes and sizes by replacing different bases 2, thus solving the problem of insufficient adaptability of conventional testing devices to stamped parts 10 with irregular shapes.
[0027] refer to Figure 1 The detection component 3 includes a pin 31 and a go / no-go gauge 32. The base 2 has mounting holes 21 corresponding to the holes of the stamped part 10. The pin 31 passes through the hole of the stamped part 10 and is inserted into the mounting hole 21. If the pin 31 can be inserted into the mounting hole 21, it means that the hole position of the stamped part 10 is qualified. If the pin 31 cannot be inserted into the mounting hole 21, it means that the hole position of the stamped part 10 is unqualified. There are multiple pins 31. The diameter of the multiple pins 31 is the same as the diameter of the hole on the stamped part 10 of different shapes. The diameter of the mounting holes 21 opened on the multiple bases 2 is the same as the diameter of the hole opened on the stamped part 10 that matches the contour.
[0028] The go / no-go gauge 32 consists of a go gauge and a no-go gauge. When the stamped part 10 is placed on the base 2 and the hole of the stamped part 10 matches the mounting hole 21 of the base 2, there is a gap between the base 2 and the stamped part 10. The maximum size of the go gauge is equal to the maximum allowable gap of the stamped part 10, and the minimum size of the no-go gauge is equal to the minimum allowable gap of the stamped part 10. Only when the go gauge can pass through the gap and the no-go gauge cannot pass through the gap can the profile of the stamped part 10 be judged to be qualified. This method transforms the abstract profile requirement into a specific physical dimension verification, eliminates the subjectivity of manual visual judgment, and ensures that the judgment standards of different inspectors are consistent.
[0029] refer to Figure 1 and Figure 2 The workbench 1 is bolted with a pin holder 6 for placing pins 31. The pin holder 6 has a fixing hole 7. The axis of the fixing hole 7 is set perpendicular to the workbench 1. One end of the pin 31 is inserted into the fixing hole 7 and engaged with the fixing hole 7. Multiple placement racks are provided. The fixing holes 7 on the multiple placement racks are adapted to pins 31 of different diameters. The multiple placement racks are engaged with the multiple pins 31.
[0030] The workbench 1 is also bolted with a storage box 8 for storing the go / no-go gauge 32. After the test is completed, the go / no-go gauge 32 is put into the storage box 8 to prevent the go / no-go gauge 32 from being scattered and lost, ensuring that it is available at any time during the test, while reducing the time spent looking for tools before the test and optimizing the test process.
[0031] The implementation principle of this application embodiment is as follows: During testing, firstly, select the appropriate base 2 according to the shape of the stamped part 10 and install it on the support platform. Place the stamped part 10 on the base 2 and adjust the stamped part 10 so that the hole position on the stamped part 10 matches the position of the mounting hole 21 opened on the base 2. Remove the appropriate pin 31 from the pin holder 6, pass the pin 31 through the hole of the stamped part 10 and check whether the pin 31 can be inserted into the mounting hole 21. If the pin 31 can be inserted smoothly, it means that the position and diameter of the hole meet the requirements; if it cannot be inserted, it is unqualified. After the hole position is checked, the pin 31 is not pulled out, which plays a role in fixing the stamped part 10 and preventing the stamped part 10 from shaking. Then, take out the go / no-go gauge 32 from the storage box 8 and use the go / no-go gauge 32 to check the gap between the stamped part 10 and the base 2 to determine whether the outline of the stamped part 10 is qualified.
[0032] Since the base 2 is detachably mounted on the workbench 1, this device can be adapted to stamping parts 10 of various shapes and sizes by replacing different bases 2, thus solving the problem of insufficient adaptability of conventional testing devices to irregularly shaped stamping parts 10.
[0033] Example 2: refer to Figure 4 and Figure 5The difference between this embodiment and the above embodiment is that the detection component 3 is no longer provided with a pin 31, and the corresponding workbench 1 is no longer provided with a pin holder 6; the mounting hole 21 on the base 2 is threaded, and the guide post 9 is screwed into the internal thread of the mounting hole 21; there are multiple guide posts 9, and the positions of the multiple guide posts 9 on the base 2 correspond to the multiple holes on the same stamping part 10 and their diameters are also compatible.
[0034] The implementation principle of this application embodiment is as follows: The guide post 9 is screwed onto the base 2 by a thread, which facilitates the installation and replacement of the guide post 9. The diameter of the guide post 9 matches the diameter of the hole on the stamping part 10, preventing the stamping part 10 from being unable to be installed on the base 2 due to the guide post 9 being too large. When installing the stamping part 10, the guide post 9 can be inserted into the hole of the stamping part 10 first, providing guidance for the placement of the stamping part 10. This helps the inspection personnel to quickly position the stamping part 10 in the correct position on the base 2, reducing the adjustment time caused by the placement deviation of the stamping part 10 and improving the preparation efficiency before inspection. At the same time, the guide post 9 can detect whether the hole position on the stamping part 10 is qualified. If the stamping part 10 can match the guide post 9 on the base 2, the stamping part 10 is qualified; otherwise, it is unqualified. The guide post 9 replaces the function of the pin 31, and correspondingly, there is no need to set up the pin bracket 6, which simplifies the device structure and reduces manufacturing costs.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
