They are characterized by a wide variety of types, complex substitutes, complex identification systems, and rapid price fluctuations.

[0003] In the automated inspection process of automotive parts, the loading device is a key piece of equipment connecting the production and inspection stages, and its performance directly affects the inspection efficiency and quality. Currently, most loading devices for automotive parts inspection on the market adopt a fixed fixture structure or are equipped with a small number of special fixtures adapted to specific specifications of parts. This design has revealed significant limitations in actual use: when automotive parts of different sizes and shapes need to be inspected, the existing loading devices are difficult to quickly and conveniently change the corresponding fixtures, resulting in low efficiency when loading and inspecting automotive parts, thus reducing the practicality of the fixture in use. Therefore, this utility model proposes a loading and unloading fixture for automotive parts inspection to solve the above problems. Utility Model Content

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a loading and unloading fixture for automotive parts inspection, including a base plate 1, a robotic arm 2 mounted on the top of the base plate 1, an mounting plate 3 mounted on one end of the robotic arm 2, an mounting cavity 4 mounted on one end of the mounting plate 3, a replacement mechanism provided inside the mounting cavity 4, a fixing cavity 5 mounted on one end of the mounting cavity 4, and a clamping mechanism provided inside the fixing cavity 5.

[0019] The replacement mechanism includes a connecting block 13, a positioning hole 14, a positioning block 15, a screw 16, a rotating wheel 17, a threaded sleeve 18, and a limiting structure. The connecting block 13 is installed at one end inside the mounting cavity 4, and one end of the connecting block 13 is connected to one end of the fixing cavity 5. A positioning hole 14 is provided inside the connecting block 13, and a positioning block 15 is disposed inside the positioning hole 14. A rotating wheel 17 is installed below one end of the mounting cavity 4, and a screw 16 is installed below the interior of the mounting cavity 4. One end of the rotating wheel 17 is connected to one end of the screw 16. A threaded sleeve 18 is provided on the outer wall of the screw 16, and the top end of the threaded sleeve 18 is connected to the bottom end of the positioning block 15. The inner diameter of the positioning hole 14 is larger than the outer diameter of the positioning block 15, and the positioning hole 14 and the positioning block 15 form a locking structure. When it is necessary to replace the fixture... When changing fixtures, rotating wheel 17 drives screw 16 to rotate, which in turn moves screw sleeve 18. Under the limit of limit rod 19 and limit sleeve 20, screw sleeve 18 drives positioning block 15 to move, pulling positioning block 15 out of positioning hole 14. At this time, connecting block 13 can be taken out from mounting cavity 4. Then, take out the new fixture, place connecting block 13 into mounting cavity 4, and rotate wheel 17 in the opposite direction to drive screw 16 to move positioning block 15 into positioning hole 14. Fix the position of the new fixture, completing the convenient replacement of fixtures. Fixing cavity 5 can be easily disassembled and installed. Different fixtures can be changed according to different automotive parts, making loading and unloading efficiency higher when inspecting different automotive parts, thus greatly improving the convenience of using the tooling.

[0020] The limiting structure includes a limiting rod 19 and a limiting sleeve 20. The limiting rod 19 is installed on one side of the lower part of the mounting cavity 4. The limiting sleeve 20 is provided on the outer wall of the limiting rod 19. The top end of the limiting sleeve 20 is connected to the bottom end of the positioning block 15. The cross-section of the limiting rod 19 is smaller than the cross-section of the limiting sleeve 20. The limiting rod 19 and the limiting sleeve 20 form a sliding structure. In use, the mutual cooperation between the limiting rod 19 and the limiting sleeve 20 can limit the movement of the positioning block 15, making the positioning block 15 more stable when moving.

[0021] The clamping mechanism includes a first servo motor 6, a threaded rod 7, a threaded sleeve 8, a clamping plate 9, a fixing groove 11, and a movable block 12. The first servo motor 6 is installed at one end of the fixed cavity 5. The threaded rod 7 is installed inside the fixed cavity 5. The output end of the first servo motor 6 is connected to one end of the threaded rod 7. The thread directions at both ends of the threaded rod 7 are opposite. Threaded sleeves 8 are symmetrically arranged at both ends of the outer wall of the threaded rod 7. A clamping plate 9 is installed at one end of each threaded sleeve 8. A fixing groove 11 is opened at the lower part of the fixed cavity 5. A movable block 12 is arranged inside the fixing groove 11. Block 12, the top end of the movable block 12 is connected to the bottom end of the threaded sleeve 8, and the inner side of the clamping plate 9 is equipped with an anti-slip pad 10. The two anti-slip pads 10 are mutually compatible. When in use, the first servo motor 6 is started to drive the threaded rod 7 to rotate. Therefore, under the limitation of the fixed groove 11 and the movable block 12, the threaded rod 7 drives the threaded sleeve 8 to move, and then drives the clamping plate 9 to move. The two clamping plates 9 and the anti-slip pads 10 are used to clamp and fix the automotive parts, making the loading of automotive parts more efficient, thereby greatly improving the practicality of the tooling in use.

[0022] Working principle: The operator first activates the robotic arm 2 to move the two clamping plates 9 to the outside of the automotive parts. Then, the first servo motor 6 is activated to drive the threaded rod 7 to rotate. Therefore, under the limitation of the fixed groove 11 and the movable block 12, the threaded rod 7 drives the threaded sleeve 8 to move, which in turn drives the clamping plates 9 to move. The two clamping plates 9 and the anti-slip pad 10 are used to clamp and fix the automotive parts. Then, the robotic arm 2 is activated again to move the clamped parts to the appropriate position for loading. When the clamps need to be replaced... Rotating the wheel 17 drives the screw 16 to rotate, which in turn moves the screw sleeve 18. Under the limitation of the limiting rod 19 and the limiting sleeve 20, the screw sleeve 18 drives the positioning block 15 to move, pulling the positioning block 15 out of the positioning hole 14. At this time, the connecting block 13 can be taken out from the mounting cavity 4. Then, take out the new fixture, place the connecting block 13 into the mounting cavity 4, and rotate the wheel 17 in the opposite direction to drive the screw 16 to move the positioning block 15 into the positioning hole 14. The position of the new fixture is fixed, completing the convenient replacement of the fixture.
