[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0015] Example: A defect detection device for cast iron parts, such as Figures 1-4 As shown, the system includes a base 1, with an observation port 11 at its center. Multiple light panels 14 are arranged around the observation port 11 on the top of the base 1. A sliding groove 12 is formed around the outer ring of the observation port 11 on the top of the base 1, within which a first turntable 2 is slidably mounted. A rack 22 is arranged around the outer ring of the first turntable 2. A first protective cover 13 is located around the outer ring of the rack 22, providing protection for it. A material placement platform 21, bent inwards, is located on the top of the first turntable 2. Multiple insertion slots 23 are formed on the inner ring of the material placement platform 21. Positioning holes 24 are formed on both sides of each insertion slot 23, and an auxiliary frame 25 is inserted into each insertion slot 23. The auxiliary frame 25 is inserted into the insertion slot 23 and a reinforcing plate 26 is provided on the top. The left and right sides of the reinforcing plate 26 are provided with positioning pins 27 that are inserted downward and interlock with the positioning holes 24. A power structure 3 that provides power to the first turntable 2 is provided on one side of the base 1. The power structure 3 includes a base plate 31, a reduction motor 32 and a gear 33. The base plate 31 is connected to the base 1 on one side. The reduction motor 32 is located on the top of the base plate 31. The gear 33 is sleeved on the output end of the reduction motor 32. A second protective cover 34 is sleeved on the top outer surface of the gear 33. The second protective cover 34 protects the gear 33. The gear 33 meshes with the rack 22 on the surface of the first turntable 2. An observation structure is provided at the bottom of the base 1 corresponding to the observation port 11.
[0016] The slide 12 has multiple storage slots 15 that communicate with the inner ring. Each storage slot 15 is equipped with an auxiliary roller 16. The auxiliary roller 16 is located at the connection between the storage slot 15 and the slide 12. The auxiliary roller 16 is used to assist the rotation of the first turntable 2 and increase the smoothness of the rotation of the first turntable 2.
[0017] The observation structure includes a base frame 41, a slider 43, and a lens frame 44. The second turntable 45 is rotatably mounted at the bottom of the base 1 and located on the outer ring of the bottom of the observation port 11. The base frame 41 is symmetrically arranged on both sides of the bottom of the second turntable 45. Each base frame 41 has a through groove 42. The slider 43 is slidably mounted in the through groove 42. The lens frame 44 is rotatably mounted between the two sliders 43. An upward-facing observation lens is provided inside the lens frame 44. The illumination surface of the observation lens is set upward, so that the internal condition of the cast iron part can be observed through the reflection of the observation lens.
[0018] The principle of this utility model is as follows: The cast iron part to be observed is placed on the top of the placement platform 21. At the same time, according to the size of the cast iron part, an auxiliary frame 25 is inserted into the insertion slot 23 of the placement platform 21. Meanwhile, the fixed plate integrally set on the top rear side of the auxiliary frame 25 is placed on the top of the placement platform 21 on both sides, and the positioning pins 27 are inserted into the corresponding positioning holes 24 on both sides to realize the installation of the auxiliary frame 25, thereby increasing the area for placing the cast iron part. Then, the light panel 14 is turned on so that the inside faces upward and shines into the inside of the cast iron part. Then, the reduction motor 32 on one side is turned on to drive the gear 33 to rotate. Thus, the gear 33 drives the rack 22 on the outer ring of the first turntable 2 to start rotating, thereby realizing the rotation of the top cast iron part. Then, the personnel can adjust the angle and height upward through the bottom mirror frame 44 to quickly observe the specific situation inside the cast iron part.
