Figure 1 As shown in the auxiliary device, one end of the lens position collar 3 is a fixed part 31 connected with the connecting piece 2, and a main body part connected with the fixed part 31, and the main body part is a circular ring structure.

[0033] When the piston ring is detected, the piston ring is arranged in the clamping groove 11 of the piston ring clamp 1, the position of the lens position collar 3 is matched with the position of the piston ring, and the camera collects the image data of the piston ring through the lens position collar 3.

[0034] Working principle: the piston ring is clamped in the clamping groove 11 of the piston ring clamp 1 by the elasticity of the piston ring, then the position of the lens position collar 3 is adjusted, the position of the lens position collar 3 is matched with the position of the piston ring, then the camera collects the image data of the piston ring through the lens position collar 3, the circular ring structure of the lens position collar 3 can provide a positioning reference for the lens of the camera, and the effect of fixing the camera lens is achieved, and the photographing quality and efficiency are improved.

[0035] In Figure 1 As shown in the auxiliary device, the piston ring clamp 1 further comprises a plurality of convex parts 4 and a limiting strip 5. Figure 1 2 As shown in the auxiliary device, six cylindrical convex parts 4 and one limiting strip 5 are arranged.

[0036] ​​The protruding part 4 and the limiting strip 5 are arranged along the extension direction of the clamping groove 11.

[0037] When the piston ring is detected, the side wall of the piston ring is in abutment with the protruding part 4, and the end of the piston ring is in abutment with the limiting strip 5.

[0038] The protruding part 4 fixes the lateral position of the piston ring, and the limiting strip 5 fixes the circumferential position of the piston ring, so that the position parameters of the piston ring are fixed during each shooting.
