[0002] An automobile is a mechanical device for transportation, usually driven by an engine and traveling on the road through tires. Its basic structure includes an engine, a transmission, a body, a suspension system, and a braking system, etc. The invention of the automobile has greatly changed people's travel mode and improved the convenience and efficiency of life. With the progress of technology, modern automobiles pay more and more attention to safety, environmental protection, and intelligence, such as being equipped with autonomous driving, intelligent navigation systems, and electric drives, etc. The automobile industry plays an important role in the global economy and promotes the development of related technologies and the construction of transportation infrastructure.

[0003] A sheet metal part refers to a metal part manufactured through sheet metal processing technology, which is commonly used in fields such as machinery, automobiles, and aviation. They are usually made of thin metal sheets and processed through processes such as cutting, stamping, bending, and welding. Sheet metal parts have the characteristics of being structurally strong, light in weight, and flexible in manufacturing, and are widely used in the production of components such as casings, brackets, and enclosures. The advantages of sheet metal processing include high efficiency, relatively low cost, and the ability to meet various complex design requirements. Modern sheet metal processing also combines advanced technologies such as laser cutting and numerical control machines, improving the processing accuracy and efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 4, An embodiment provided by the present utility model: An automotive sheet metal part inspection fixture, including a workbench 1. A motor 2 is fixedly connected to the inner bottom wall of the workbench 1. The output end of the motor 2 is fixedly connected to a first gear 3. The inner top wall of the workbench 1 is rotatably connected to a turntable 4. A second gear 5 is fixedly connected to the bottom of the turntable 4. The second gear 5 meshes with the first gear 3. Four sliding grooves 6 are formed inside the turntable 4. A sliding rod 7 is slidably connected inside the sliding groove 6. A clamping block 8 is fixedly connected to the top of the sliding rod 7. A limiting rod 9 is slidably connected inside the sliding rod 7. A lathe 10 is arranged on the top of the workbench 1. A disassembly and assembly component is installed in the middle of the lathe 10. The disassembly and assembly component is used for quickly disassembling and installing detection heads for different purposes. The outside of the sliding rod 7 is slidably connected to the inner part above the workbench 1. The bottom of the clamping block 8 is slidably connected to the top of the workbench 1. The outside of the limiting rod 9 is fixedly connected to the inner part above the workbench 1. The outside of the second gear 5 is sleeved inside the workbench 1. The outside of the first gear 3 is sleeved inside the workbench 1.

[0032] Specifically, the workbench 1 is used to connect and protect the internal parts for convenient operation. The motor 2 is to drive the rotation of the first gear 3. The first gear 3 is used to make the second gear 5 rotate. Both the first gear 3 and the second gear 5 are bevel gears. The turntable 4 rotates on the inner top wall of the workbench 1 through the second gear 5. The sliding groove 6 is used to drive the movement of the sliding rod 7. The clamping block 8 is to clamp the sheet metal part. Among them, there are grooves with different depths on the surface of the clamping block 8 to be able to clamp workpieces of different sizes. The limiting rod 9 is used to limit the movement direction of the sliding rod 7 to ensure that the sliding rod 7 can only move in the specified direction without random movement. The lathe 10 is to drive the micrometer 16 to move randomly within the range of the workbench 1 for detecting the sheet metal part.

[0033] Refer to Figure 1 - Figure 4 , The disassembly and assembly component includes a housing 11. The top of the housing 11 is fixedly connected to the middle of the lathe 10. A spring 12 is fixedly connected to the inner top wall of the housing 11. A baffle 13 is fixedly connected to the bottom of the spring 12. A pull rod 14 is fixedly connected to the bottom of the baffle 13. A first card slot 15 is formed on the left side of the pull rod 14. A micrometer 16 is slidably connected inside the housing 11. A second card slot 17 is formed on the rear side of the micrometer 16. The left side of the pull rod 14 is slidably connected inside the first card slot 15. The rear side of the micrometer 16 is slidably connected inside the first card slot 15. The outside of the baffle 13 is slidably connected to the inner wall of the housing 11. The outside of the pull rod 14 is slidably connected inside the housing 11.

[0034] Specifically, the housing 11 is used to connect and protect the internal parts. The spring 12 is to apply pressure to the baffle 13 and drive the synchronous movement of the pull rod 14 at the same time. The baffle 13 bears the thrust from the spring 12 and drives the pull rod 14 to reset. The pull rod 14 is used to cooperate with the second card slot 17 to lock the micrometer 16 on the housing 11. The first card slot 15 is to unlock the micrometer 16. The micrometer 16 is used to detect the machining accuracy of the sheet metal part. The second card slot 17 is to fix the micrometer 16.

[0035] Working principle: When using this device, first place the sheet metal part on the workbench 1, and control the motor 2 to drive. The motor 2 drives the first gear 3 to rotate, and meshes with the second gear 5 to drive the turntable 4 to rotate. Under the limitation of the limit rod 9, the chute 6 drives the slide rod 7 to make the four clamping blocks 8 move synchronously towards the middle to clamp the workpiece. At this time, the workpiece has been locked. Then control the lathe 10 to drive the micrometer 16 to move back and forth on the workpiece to detect the machining accuracy of the workpiece. Then, if it is necessary to replace other different detection heads to continue detecting other data of the workpiece, first press the pull rod 14 to drive the baffle 13 to compress the spring 12, so that the second card slot 17 is disengaged from the pull rod 14, and the micrometer 16 is fitted with the first card slot 15. At this time, the micrometer 16 has been unlocked. After pulling out the micrometer 16 and inserting a detection head with other functions, then release the pull rod 14, and the spring 12 will immediately push the baffle 13 to drive the pull rod 14 to reset, so that the second card slot 17 is engaged with the pull rod 14 again to achieve replacement and fixation.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
