[0031] Working principle: The loading mechanism 30 pushes the automobile parts to be inspected into the groove 4 opened inside the processing frame 2. The automobile parts are located above the bottom plate 10. The motor 3 is connected to the external power supply. The motor 3 drives the processing frame 2 to rotate, thereby driving the automobile parts to move to the corresponding position of the cleaning part 11 for rest.

[0032] Under the action of the support frame 28, the electric push rod 29 is connected to the external power supply, and the electric push rod 29 drives the push plate 25 to move toward the direction of the automobile part. The push plate 25 drives the cleaning part 11 to be inserted into the inside of the threaded hole. The protrusion 12 is a water-absorbing material and can absorb water stains inside the threaded hole. The No. 1 sleeve 13 can drive the automobile part to move synchronously when it contacts the automobile part. The automobile part drives the mounting plate 8 to move toward the center of the processing frame 2 through the adjustment plate 7, and the mounting plate 8 drives the connecting plate 9 to rotate, thereby pulling the two sets of clamps 5 closer to each other inside the groove 4, limiting the position of the automobile part, so that the automobile part will not shake when the threaded hole is cleaned.

[0033] When the No. 1 sleeve 13 stops moving, the No. 2 sleeve 14 can move inside the No. 1 sleeve 13 toward the cleaning piece 11, and the No. 2 sleeve 14 slides outside the rod 16. The No. 1 spring 17 is deformed by the force. At this time, the baffle 18 blocks the through hole 15, and the No. 2 sleeve 14 can transport the air inside the No. 1 sleeve 13 to the inside of the cleaning piece 11. The cleaning piece 11 is made of rubber. The air inside the cleaning piece 11 continues to increase, and the volume of the cleaning piece 11 increases, so that threaded holes of different sizes can be cleaned.

[0034] As the No. 2 sleeve 14 continues to move, the push block 21 contacts the limit block 19, and the push block 21 pushes the limit block 19 to move in the direction of the baffle 18. The No. 2 sleeve 14 stops moving, and the push plate 25 drives one of the sets of racks 23 to move in the direction of the gear 24. The No. 2 sleeve 14 can slide on the outside of the slide rod 26, and the No. 3 spring 27 is deformed by the force. Since both sets of racks 23 are engaged with the gear 24, the other set of racks 23 can drive the piston plate 22 to move away from the cleaning piece 11. The piston plate 22 extracts the air between the piston plate 22 and the cleaning piece 11, and the air pressure drives the baffle 18 to rotate. At this time, the through hole 15 is in an open state, and the air pressure draws the cleaning piece 11 into the interior of the No. 1 sleeve 13, and the impurities inside the threaded hole can enter the interior of the cleaning piece 11, which is convenient for cleaning the threaded hole and ensuring the detection effect.

[0035] The processing frame 2 drives the cleaned automobile parts to continue to rotate to the position of the detection mechanism 31 for a rest. The detection mechanism 31 can detect the depth of the threaded holes of the automobile parts. After the detection is completed, the processing frame 2 drives the automobile parts to move above the unloading port 32. Under the action of gravity, the automobile parts drive the bottom plate 10 to rotate. The automobile parts can fall from above the bottom plate 10 and be unloaded from the unloading port 32. After the automobile parts are unloaded, under the action of the elastic member, the elastic member drives the bottom plate 10 to reset, which is convenient for the detection of the next automobile part.

[0036] It should be noted that the optimal number of grooves 4 is four groups. Both the splint 5 and the interior of the grooves 4 are magnetic and attract each other, so that when the processing frame 2 drives the automobile part to move, the splint 5 does not clamp the automobile part. Only when the automobile part is being processed, the splint 5 will limit the automobile part.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
