[0002] In automobile manufacturing, precision control of body structural components is particularly critical. As vital load-bearing components connecting the suspension system to the core body structure, front and rear shock absorber towers are commonly produced using die casting. These parts are not only complex in shape but also need to withstand enormous dynamic loads during vehicle operation; therefore, the dimensional accuracy and deformation tolerances after die casting must be strictly controlled. Currently, the industry mainly relies on coordinate measuring machines (CMMs) or manual fixtures for inspection. However, these methods have significant limitations: low inspection efficiency, strong dependence on operator experience, susceptibility to subjective errors, and difficulty in achieving full inspection of every single part on the production line. These problems have become key bottlenecks restricting the improvement of production automation and further optimization of quality control capabilities. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] This utility model provides an automatic testing device for die-cast components of front and rear shock absorber towers in automobile bodies, including an industrial control platform 1 and a testing mechanism 2. The industrial control platform 1 includes a frame 3, on which a workbench 4 and an industrial computer 5 are fixedly installed. The workbench 4 is fixedly installed with the testing mechanism 2 via a connecting block 6. The testing mechanism 2 includes a bracket 7, on which a mold 8 is provided. The mold 8 is fixedly installed with a first side edge testing unit 9, a second side edge testing unit 10, an outer side testing unit 11, an inner testing unit 12, and a middle testing unit 13. The first side edge testing unit 9, the second side edge testing unit 10, the outer side testing unit 11, the inner testing unit 12, and the middle testing unit 13 are all equipped with test components 14 of the same structure. The test components 14 include a magnet 15 and a pneumatic displacement testing unit 16. The magnet 15 is fixedly connected to a contact element 17. The internal detection unit 12 includes a fixed base 18, on which two test components 14 are fixedly mounted. The external detection unit 11 includes a fixed plate 19, on which the test components 14 are symmetrically mounted. The central detection unit 13 includes an extension base 20, on which two test components 14 are fixedly mounted. A drawer 21 is fixedly mounted on the bracket 7. A quick control panel 22 is fixedly mounted on the bracket 7, and buttons 23 are fixedly mounted on the quick control panel 22. A proximity sensing component 24 is fixedly mounted on the mold 8. A stop block 25 is fixedly mounted on the mold 8.

[0023] Through the above technical solution, during operation, the shock absorber tower die-cast component is fitted onto mold 8. Detection units distributed on mold 8 simultaneously detect the dimensions of the shock absorber tower die-cast component and return the data to the industrial control computer 5 (not part of the industrial control platform 1) for calculation, determining whether the shock absorber tower die-cast component is qualified. Specifically, the surface of the shock absorber tower die-cast component contacts the test assembly 14 of the detection unit. The test assembly 14 includes a magnet 15 and a pneumatic displacement test unit 16. The magnet 15 and the pneumatic displacement test unit 16 are fixed to the fixing component of the detection unit. The magnet 15 is fixedly connected to... Contact element 17 is L-shaped. During the testing process, contact element 17 directly contacts the surface of the shock absorber tower die-cast component. Magnet 15 attracts and fixes one end of contact element 17, providing a stable adsorption force. When pressure is applied, the other end of contact element 17 is pressed down and applied to the pneumatic displacement testing unit 16 to achieve the flatness detection function. The testing component 14 has a simple structure and accurate detection, reducing manufacturing costs. The detection units distributed and installed on the mold 8 simultaneously and automatically detect the dimensions of the shock absorber tower die-cast component, improving detection efficiency and accuracy.

[0024] The industrial control platform 1 and the testing mechanism 2 of this utility model adopt a detachable design. The bracket 7 of the testing mechanism 2 is equipped with a mold 8, which allows for easy replacement of different models of mold 8 according to processing requirements, thus improving compatibility. The industrial control platform 1 and the testing mechanism 2 are connected via a wire harness or wireless signal communication.

[0025] Example 2:

[0026] The industrial control platform 1 in this embodiment includes a frame 3, on which a workbench 4 and an industrial control computer 5 are fixedly mounted. The workbench 4 is fixedly mounted with a testing mechanism 2 via a connecting block 6. The testing mechanism 2 includes a bracket 7, on which a mold 8 is mounted. The mold 8 is fixedly mounted with a first side edge testing unit 9, a second side edge testing unit 10, an outer side testing unit 11, an inner testing unit 12, and a central testing unit 13. These testing units are all equipped with test components 14 of the same structure. The test components 14 include a magnet 15 and a pneumatic displacement testing unit 16. The magnet 15 is fixedly connected to a contact element 17. During the testing process, the shock absorber tower die-cast component is fitted onto the mold 8. Multiple testing units distributed on the mold 8 simultaneously detect the component dimensions and feed the test data back to the industrial control computer 5 for calculation to determine whether the component is qualified.

[0027] The surface of the die-cast component of the shock absorber tower comes into contact with the test assembly 14 in each testing unit. The test assembly 14 includes a magnet 15 and a pneumatic displacement testing unit 16, both of which are fixed to the fixed component of the testing unit. The magnet 15 is connected to a contact element 17, which directly contacts the surface of the component during testing. The magnet 15 attracts one end of the contact element 17, providing a stable attraction force; when the other end of the contact element 17 is pressed, the pressure is transmitted to the pneumatic displacement testing unit 16 to achieve flatness detection. This test assembly 14 has a simple structure and accurate detection, which helps to reduce manufacturing costs. Synchronous automatic detection by the testing units distributed on the mold 8 effectively improves the detection efficiency and accuracy.

[0028] The industrial control platform 1 and the inspection mechanism 2 adopt a detachable design. The bracket 7 of the inspection mechanism 2 is equipped with a mold 8, which can be easily replaced with different models of mold 8 according to processing requirements, improving compatibility. This design allows the equipment to adapt to different specifications of shock absorber tower die-casting parts without replacing the entire inspection mechanism 2. Only the mold 8 needs to be adjusted to achieve rapid switching, thereby optimizing the flexibility and adaptability of the production line. During operation, the industrial control computer 5 receives data from each inspection unit, performs real-time analysis and comparison, and automatically outputs the inspection results to ensure that each part meets the preset tolerance standards.

[0029] In this embodiment, the layout of the detection units is optimized for the complex shape of the shock absorber tower die-cast components. The first side edge detection unit 9 and the second side edge detection unit 10 respectively cover the two side edge areas of the component. The outer side detection unit 11 is responsible for detecting the outer surface of the component, the inner detection unit 12 focuses on the internal structure, and the central detection unit 13 targets the central area of ​​the component. This comprehensive coverage design ensures that all key parts of the component can be accurately measured, avoiding the omission of any potential defects. Through synchronous detection, the equipment can complete 100% inspection in a short time, significantly improving production efficiency and product quality control.

[0030] During the testing process, the pneumatic displacement testing unit 16 accurately measures the displacement of the component surface based on the pressure changes transmitted by the contact element 17, and transmits the data to the industrial control computer 5 in real time. The industrial control computer 5 uses built-in algorithms to process the data, calculate the dimensional deviation and deformation degree of the component, and compare it with standard values. If the test results exceed the allowable range, the equipment automatically marks the unqualified component for subsequent processing. This automated process reduces human intervention, lowers the risk of subjective error, and ensures the reliability and consistency of the test results.

[0031] The application of this equipment embodiment solves the problems of low efficiency and reliance on experience in traditional testing methods, enabling rapid and accurate full inspection of every die-cast component of the shock absorber tower on the production line. Through modular design and a synchronous testing mechanism, it not only improves testing speed and accuracy but also enhances the equipment's versatility and ease of maintenance, providing an efficient solution for quality control in the automotive manufacturing industry.

[0032] Example 3:

[0033] The internal detection unit 12 of this embodiment includes a fixed base 18, on which two test components 14 are fixedly mounted. The outer side detection unit 11 includes a fixed plate 19, on which the test components 14 are symmetrically mounted. The middle detection unit 13 includes an extension base 20, on which two test components 14 are mounted. The fixed base 18 and the fixed plate 19 have the same function: to adjust the height and position of the test components 14 to accommodate the concave and convex shapes of the shock absorber tower die-cast parts. During equipment operation, the shock absorber tower die-cast parts are fitted onto the mold 8. Multiple detection units distributed on the mold 8 synchronously detect the dimensions of the parts and feed the detection data back to the industrial control computer 5 for calculation to determine whether the parts are qualified. Specifically, the surface of the shock absorber tower die-cast parts contacts the test components 14 in each detection unit. The test components 14 include a magnet 15 and a pneumatic displacement testing unit 16, both of which are fixed to the fixed components of the detection unit. The magnet 15 is connected to a contact element 17, which directly contacts the surface of the parts during the detection process. Magnet 15 attracts one end of contact 17, providing a stable adsorption force; when the other end of contact 17 is pressed, the pressure is transmitted to pneumatic displacement testing unit 16 to achieve flatness detection. This testing assembly 14 has a simple structure and accurate detection, which helps to reduce manufacturing costs. Synchronous automatic detection by the detection units distributed on mold 8 effectively improves detection efficiency and accuracy.

[0034] In the internal testing unit 12, the mounting base 18 serves as a support structure, capable of adjusting the position of the test assembly 14 according to the internal contour of the shock absorber tower die-cast component, ensuring a tight fit between the contact element 17 and the component surface. The design of the mounting base 18 allows for fine-tuning of the test assembly 14 in both vertical and horizontal directions to accommodate the complex geometry of the component. Magnets 15 within the test assembly 14 maintain the stability of the contact element 17 through magnetic attraction, preventing displacement during testing. The pneumatic displacement testing unit 16 receives the pressure signal transmitted by the contact element 17 and converts it into displacement data for evaluating the flatness and dimensional accuracy of the component. This arrangement ensures comprehensive coverage of the internal area, avoiding areas that might be missed in traditional testing methods and improving the reliability of the testing.

[0035] The test assembly 14 is symmetrically mounted on the fixing plate 19 in the outer surface inspection unit 11. This symmetrical design helps balance the inspection force and reduces the risk of deformation of the component during the inspection process. The fixing plate 19 can adjust the height and angle of the test assembly 14 to adapt to the irregular surface of the outer surface of the shock absorber tower die-cast component. The contact element 17 in the test assembly 14 contacts the component surface under the action of the magnet 15. When there are unevenness on the component surface, the contact element 17 will apply pressure, and the displacement change will be recorded by the pneumatic displacement test unit 16. This mechanism can quickly identify the dimensional deviation of the outer surface and transmit the data to the industrial control computer 5 for processing in real time. The adjustability of the fixing plate 19 ensures the flexibility of the inspection and is suitable for different models of shock absorber tower components.

[0036] The central inspection unit 13 uses an extension base 20 as its fixing structure. The extension base 20 mounts two test components 14 for inspecting the central region of the shock absorber tower die-cast components. The design of the extension base 20 allows the test components 14 to move along the central axis of the component to cover a wider inspection range. The magnet 15 and the pneumatic displacement test unit 16 in the test components 14 work together. The magnet 15 provides a stable attraction force, ensuring constant contact between the contact element 17 and the component surface, while the pneumatic displacement test unit 16 accurately measures displacement changes caused by surface unevenness. This arrangement effectively captures subtle deformations in the central region and integrates the inspection data into the overall evaluation, ensuring that the component's performance under dynamic loads meets standards.

[0037] Throughout the testing process, the industrial control platform 1 and the testing mechanism 2 adopt a detachable design. The bracket 7 of the testing mechanism 2 is equipped with a mold 8, which facilitates the replacement of different models of mold 8 according to processing requirements, improving equipment compatibility. The first side edge testing unit 9, the second side edge testing unit 10, the outer side testing unit 11, the inner testing unit 12, and the middle testing unit 13 distributed on the mold 8 all use the same structure of test components 14, ensuring the consistency and repeatability of the testing. Through synchronous automatic testing, the equipment can quickly process multiple testing points, reduce human intervention, and improve the automation level of the production line. After receiving all testing data, the industrial control computer 5 performs real-time calculations and analysis, and outputs the judgment result of whether it is qualified or not, thereby achieving efficient quality control of the die-cast components of the shock absorber tower.

[0038] Example 4:

[0039] The industrial control platform 1 in this embodiment consists of a frame 3, a workbench 4, and an industrial control computer 5. The testing mechanism 2 is fixedly installed on the workbench 4 via a connecting block 6. The core component of the testing mechanism 2 is a bracket 7, on which a mold 8 is mounted. Multiple testing units are distributed on the mold 8, including a first side edge testing unit 9, a second side edge testing unit 10, an outer side surface testing unit 11, an inner testing unit 12, and a central testing unit 13. These testing units all use test components 14 with the same structure. Each test component 14 includes a magnet 15 and a pneumatic displacement testing unit 16. The magnet 15 is fixedly connected to a contact element 17. During the testing process, the shock absorber tower die-cast component is fitted onto the mold 8. Each testing unit works synchronously. The contact element 17 is in direct contact with the surface of the component. The magnet 15 provides a stable adsorption force. When the contact element 17 is pressed, the pressure is transmitted to the pneumatic displacement testing unit 16, thereby measuring the flatness of the component. The test data is fed back to the industrial control computer 5 in real time for calculation and analysis to determine whether the component is qualified. This design enables efficient and accurate automated detection, avoiding the subjective error problems caused by reliance on manual operation in traditional methods.

[0040] In this embodiment, a drawer 21 is fixedly installed on the bracket 7. Located in the lower part of the bracket 7, the drawer 21 facilitates the storage of frequently used items and tools by workers during operation. The drawer 21 employs a sliding structure and is tightly connected to the main body of the bracket 7, ensuring that it will not loosen or shift during equipment operation. The internal space of the drawer 21 is rationally designed to accommodate tools and testing aids of various sizes, such as wrenches, screwdrivers, and calipers. When workers are debugging, maintaining, or changing the mold 8, they can easily retrieve the necessary tools from the drawer 21 without leaving the work area, thus saving time and improving work efficiency. The installation position of the drawer 21 is optimized so as not to interfere with the normal operation of the testing mechanism 2 or affect the mold 8 replacement process. This design fully considers the operational convenience in the actual production environment, enabling workers to quickly respond to equipment needs and reducing non-productive time waste.

[0041] During equipment operation, the presence of drawer 21 further enhances the equipment's practicality and user-friendly design. For example, when the inspection unit requires periodic calibration or cleaning, workers can immediately retrieve specialized tools from drawer 21 for operation, without needing to search for or prepare additional tools. Furthermore, in a mass production environment, workers may need to continuously inspect multiple shock absorber tower die-cast components; the spare parts or recording tools stored in drawer 21 can help them promptly handle unexpected problems, such as replacing worn contact parts 17 or recording inspection data. The drawer 21 has a simple and reliable structure, consistent with the overall design of the bracket 7, without increasing the complexity of the equipment or manufacturing costs. Through this integrated design, the automated inspection equipment not only achieves high-precision dimensional control but also optimizes the operating process, improving the overall automation level of the production line and worker satisfaction.

[0042] The automated inspection equipment in this embodiment effectively solves the problem of inconvenient tool management in traditional inspection methods through the drawer 21 fixedly installed on the bracket 7. The design of the drawer 21 is based on actual production needs, emphasizing practicality and ease of use, enabling workers to maintain efficiency and focus in high-intensity working environments. At the same time, the installation of the drawer 21 does not affect the core function of the inspection mechanism 2, ensuring the stability and reliability of the equipment during long-term operation. This detailed optimization reflects the comprehensiveness of the equipment design, focusing not only on technical performance but also on the user experience of operators, thereby promoting continuous improvement in quality control and production efficiency in the automotive manufacturing field.

[0043] Example 5:

[0044] In this embodiment, the bracket 7 is fixedly mounted with a quick control panel 22, which has buttons 23 for easy execution of testing commands by the operator. The quick control panel 22 is connected to the industrial computer 5 via internal wiring to achieve command transmission and data interaction. When the operator presses button 23, the panel sends a signal to the industrial computer 5 to start the testing process, eliminating the need for complex settings and simplifying the operation. This design reduces operation time and improves testing efficiency, making it particularly suitable for continuous operation environments on production lines.

[0045] During the testing process, the operator places the shock absorber tower die-cast component onto mold 8. Mold 8 has multiple testing units distributed on it, including a first side edge testing unit 9, a second side edge testing unit 10, an outer side testing unit 11, an inner testing unit 12, and a central testing unit 13. Each testing unit is equipped with a test assembly 14 of the same structure, which includes a magnet 15 and a pneumatic displacement testing unit 16. The magnet 15 is fixedly connected to a contact element 17. When the component comes into contact with the contact element 17, the magnet 15 provides an attractive force, ensuring the contact element 17 stably adheres to the component surface. The pneumatic displacement testing unit 16 measures the component's dimensional deviation based on the pressure changes transmitted by the contact element 17. The buttons 23 on the quick control panel 22 allow the operator to quickly start or pause the testing process without relying on external equipment, further optimizing the operation.

[0046] The installation location of the quick control panel 22 is optimized, situated in an easily accessible area of ​​the bracket 7, ensuring that operators can complete operations without moving the device. The panel buttons 23 have a simple layout and clearly defined functions, including start, stop, and reset buttons 23, facilitating rapid response to testing needs. When testing data is fed back to the industrial computer 5, the panel can display basic status information, such as testing progress or result prompts, helping operators adjust operations promptly. This design not only improves testing efficiency but also reduces the error rate, making it suitable for high-frequency testing scenarios.

[0047] During equipment operation, the quick control panel 22 works in conjunction with the inspection mechanism 2 to achieve an automated inspection process. Operators can quickly initiate inspection via button 23. Multiple inspection units on the mold 8 simultaneously perform measurements and transmit the data in real time to the industrial control computer 5 for analysis. If a component is detected as non-conforming, the panel can issue a prompt, and operators can immediately perform a reset or re-inspection operation via button 23. This integrated design reduces manual intervention, improves the consistency and reliability of inspections, and adapts to the needs of different production cycles.

[0048] Furthermore, the quick-access control panel 22 is designed for compatibility, matching the detachable inspection mechanism 2. When changing to different models of molds 8, the panel's functions remain unchanged, eliminating the need for operators to relearn the operating procedures and ensuring flexible equipment application. By simplifying the user interface, the panel reduces training costs, enabling new employees to quickly get started and further improving overall production efficiency. This embodiment demonstrates the equipment's efficient and precise inspection capabilities in automobile manufacturing, meeting the requirements for high-precision component quality control.

[0049] Example 6:

[0050] In this embodiment, a proximity sensing component 24 is fixedly installed on the mold 8. This component consists of multiple sensing units evenly distributed at various key locations on the mold 8. These sensing units are used to monitor in real time whether the shock absorber tower die-casting component is accurately fitted onto the mold 8 and to determine whether its installation position meets the preset standard. When the shock absorber tower die-casting component is placed on the mold 8, the proximity sensing component 24 senses the relative position between the component and the mold 8 in a non-contact manner. If the component is not fully in place or is offset, the sensing component will immediately send a signal to prevent errors caused by improper installation during subsequent inspection. This design ensures consistent initial conditions for inspection, providing a reliable basis for subsequent dimensional inspection.

[0051] The proximity sensing component 24 operates based on electromagnetic induction or optical principles, specifically through a sensing probe and a signal processing unit. The sensing probe is mounted on the surface of the mold 8. When the shock absorber tower die-cast component approaches, the probe detects the metallic or specific material properties of the component's surface, generating a sensing signal. The signal processing unit receives and analyzes these signals to determine whether the component completely covers the predetermined area of ​​the mold 8. If the component is properly installed, the sensing component outputs a confirmation signal, allowing the detection mechanism 2 to initiate subsequent tests; otherwise, the system pauses the detection process, prompting the operator to adjust the component's position. This mechanism effectively avoids misjudgments caused by misalignment or looseness of the component, improving the overall accuracy of the detection.

[0052] During the testing process, the proximity sensing component 24 works in conjunction with other testing units on the mold 8, including the first side edge testing unit 9, the second side edge testing unit 10, the outer side testing unit 11, the inner testing unit 12, and the central testing unit 13. These testing units all use the same test assembly 14 structure, which includes a magnet 15 and a pneumatic displacement testing unit 16. Once the proximity sensing component 24 confirms that the shock absorber tower die-cast component is properly installed, all testing units are activated simultaneously. The contact element 17 in the test assembly 14 contacts the component surface, and the magnet 15 provides a stable adsorption force, ensuring that the contact element 17 remains in a fixed position during testing. The pneumatic displacement testing unit 16 measures the component dimensions based on the displacement changes of the contact element 17, and the data is transmitted in real time to the industrial control computer 5 for analysis. The introduction of the proximity sensing component 24 strengthens the initial verification stage of the testing, ensuring that all testing units operate under the premise that the component is correctly installed, thereby improving testing efficiency and accuracy.

[0053] In this embodiment, the distribution design of the proximity sensing components 24 takes into account the complex shape of the shock absorber tower die-cast parts. The sensing units are arranged in areas where the parts are prone to misalignment or displacement, such as edges and connection points. This layout ensures comprehensive coverage, allowing timely detection even if slight deviations occur during component installation. Simultaneously, the signals from the proximity sensing components 24 are integrated with the industrial control platform 1. The industrial control computer 5 dynamically adjusts the detection parameters based on the sensing data, further optimizing the judgment logic. In this way, the automatic inspection equipment achieves full automation from component installation to dimensional inspection, reducing human intervention and making it suitable for large-scale production environments of high-precision automotive parts.

[0054] Furthermore, the mounting method of the proximity sensing component 24 is compatible with the detachable design of the mold 8, facilitating the replacement of the mold 8 and the sensing component according to different models of shock absorber tower die-casting parts. This flexibility allows the equipment to quickly adapt to changes in production needs while maintaining consistency and reliability in inspection. In practical applications, the proximity sensing component 24 not only improves the initial accuracy of inspection but also extends the service life of the equipment by reducing mechanical wear caused by incorrect component installation. Overall, this embodiment, by integrating the proximity sensing component 24, solves the problems of low efficiency and high error in traditional inspection methods, promoting the improvement of automation levels in automotive manufacturing.

[0055] Example 7:

[0056] In this embodiment, the mold 8 is fixedly equipped with a stop block, which is located on the side edge of the mold 8. When the shock absorber tower die-casting component is fitted onto the mold 8, the inclined structure of the stop block can guide the component to be smoothly positioned, preventing the component from shifting or misaligning during installation. This helps to correct the position of the component and ensures the precise fit between the component and the mold 8. This design significantly improves the installation speed of the shock absorber tower die-casting component, thereby improving the overall testing efficiency.

[0057] During equipment operation, the shock absorber tower die-cast components are fitted onto mold 8. Mold 8 has multiple detection units distributed on it, including a first side edge detection unit 9, a second side edge detection unit 10, an outer side detection unit 11, an inner detection unit 12, and a central detection unit 13. These units all use the same test assembly 14, which consists of a magnet 15 and a pneumatic displacement test unit 16. The magnet 15 is fixedly connected to a contact element 17. When the surface of the component comes into contact with the contact element 17, the magnet 15 provides a stable adsorption force, making the contact element 17 adhere tightly to the surface of the component. During the detection process, the contact element 17 is pressed and transmits the pressure to the pneumatic displacement test unit 16, achieving accurate measurement of the component's flatness. All detection units work synchronously, feeding back the detection data to the industrial control computer 5 in real time for calculation and analysis, in order to quickly determine whether the component is qualified. This synchronous detection mechanism not only improves the detection accuracy but also significantly shortens the detection time.

[0058] The industrial control platform 1 and the testing mechanism 2 adopt a detachable design. The mold 8 is installed on the bracket 7 of the testing mechanism 2. This structure makes it easy to replace the mold 8 according to different processing requirements, which enhances the compatibility and adaptability of the equipment. The addition of the stop further optimizes the component installation process, reduces manual intervention, and ensures the stability and repeatability of the testing process. With the assisted positioning of the inclined surface of the stop, the component can be quickly and accurately fixed on the mold 8, avoiding the testing error caused by position deviation, thereby ensuring the reliability of the testing results.

[0059] The design principle of the stop block is based on the guiding effect of the inclined plane. When installing the die-cast components of the shock absorber tower, the inclined plane can gradually guide the components into the correct position, preventing the components from tilting or getting stuck during the installation process. This mechanical assistance method not only simplifies the operation steps, but also reduces the skill requirements of the operators, making the equipment easier to promote and apply on the production line. The fixed installation of the stop block ensures its stability and durability, and will not fail due to frequent use, thus maintaining long-term high-efficiency detection performance.

[0060] Overall, the introduction of the stop block and the collaborative work of the detection unit have enabled the full automation of the installation and inspection process of the shock absorber tower die-cast components. The inclined design of the stop block directly addresses the issue of component position correction, improving installation efficiency, while the multi-point synchronous detection of the detection unit ensures comprehensive control of dimensional accuracy. This combination effectively solves the problems of low efficiency and subjective error in traditional detection methods, and promotes the automation and standardization of quality control of die-cast components in automobile manufacturing.
