[0002] Flanges are disc-shaped mechanical parts used for detachable connections between pipes or equipment. They achieve sealing through bolts and gaskets and are widely used in industrial fields. After machining, flanges require quality inspection of their machined surfaces. This includes checking for smoothness and the absence of forging marks, cracks, and other defects; removing adhering sand and oxide scale; ensuring the machined surfaces are free of burrs, harmful scratches, and other defects that reduce flange strength and connection reliability; and inspecting each ring connection surface for surface defects such as cracks, scratches, and impact damage caused by machining.
[0003] When the flange is a large flange ring, the staff needs to use handheld testing equipment to inspect the surface quality around the large flange ring. This method is labor-intensive for the staff, and the testing equipment may not be strictly inspecting around the circumference of the large flange ring, which may result in some areas being missed.

[0038] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0039] Example
[0040] This embodiment of a large flange ring surface quality inspection device with rotation function includes a support mechanism 1, a rotating platform 2, a horizontal moving mechanism and a vertical moving mechanism.
[0041] The rotating platform 2 is horizontally rotatably mounted on the support mechanism 1 and shares the same axis with the support mechanism 1; the rotating platform 2 is equipped with a motor for driving the rotating platform 2 to rotate.
[0042] like Figure 1 As shown, the lateral moving mechanism includes a lateral support frame 3 and a first lead screw 4; the lateral support frame 3 is fixed on the rotating platform 2 along the radial direction of the rotating platform 2; the first lead screw 4 is horizontally rotatably disposed within the lateral support frame 3.
[0043] like Figure 2As shown, the vertical moving mechanism includes a vertical support frame 5, a second lead screw 6, and a detection assembly; the vertical support frame 5 is threaded onto the first lead screw 4; the second lead screw 6 is vertically and rotatably disposed within the vertical support frame 5; as shown... Figure 3 As shown, the detection assembly includes a support base 7 and a detection head 8; the support base 7 is threaded onto the second lead screw 6; the detection head 8 is vertically downward mounted on the support base 7.
[0044] When inspecting a large flange ring, the large flange ring is placed flat on the ground. Then, the large flange ring surface quality inspection device with rotation function of this embodiment is lifted into the large flange ring by an external lifting device, so that the large flange ring and the surface quality inspection device share the same axis. The first lead screw 4 is rotated so that the vertical moving mechanism moves horizontally to be directly above the surface of the large flange ring to be inspected. Then, the second lead screw 6 is rotated so that the inspection component moves vertically until the distance between the inspection head 8 and the surface to be inspected is matched. Then, the rotating platform 2 is driven to rotate, and the inspection head 8 can perform inspection around the circumference of the large flange ring. When the wall thickness of the large flange ring is relatively thick, the vertical moving mechanism can be moved radially by rotating the first lead screw 4, and then inspection can be performed again.
[0045] In this embodiment, the horizontal support frame 3 is provided with first guide posts 9 on both the upper and lower sides of the first lead screw 4, and the vertical support frame 5 is slidably sleeved on the first guide posts 9; this arrangement effectively ensures the accuracy of the moving direction of the vertical support frame 5 and avoids it from shaking during the movement.
[0046] Similarly, the vertical support frame 5 is provided with second guide posts 10 on both the left and right sides of the second lead screw 6, and the support seat 7 is slidably sleeved on the second guide posts 10.
[0047] In this embodiment, in order to facilitate the rotation of the first lead screw 4 and the second lead screw 5, both the ends of the first lead screw 4 and the second lead screw 5 are provided with handles 11.
[0048] In this embodiment, the bottom of the support mechanism 1 is provided with a housing 12, and a plurality of support rods 13 are horizontally slidably arranged in a circular array on the side of the housing 12, with each support rod 13 arranged radially along the housing 12; the top of the housing 12 is provided with a driving device for driving the support rods to slide. With this configuration, after the large flange ring surface quality inspection device with rotation function of this embodiment is lifted into the large flange ring, the support rods 13 are extended by driving the driving device, so that the end of each support rod 13 abuts against the inner wall of the large flange ring, allowing the large flange ring and the surface quality inspection device of this embodiment to share the same axis, resulting in fast adjustment speed.
[0049] Specifically, such as Figure 4 As shown, the driving device is a cylinder 14. The piston rod of the cylinder 14 slides vertically downward through the center of the housing 12. A driving block 15 is fixed to the end of the piston rod of the cylinder 14. The upper end of the driving block 15 is larger than the lower end. The side of the driving block 15 has several planes, each of which is directly opposite the end of a support rod 13. A matching inclined block 16 is provided on the end of the support rod 13 near the driving block 15. A spring 17 is sleeved on the part of the support rod 13 located inside the housing 12. With this configuration, when the piston rod of the cylinder 14 moves downward, the driving block 15 also moves downward. Under the action of the driving block 15 and the inclined block 16, all the support rods 13 slide outward until they abut against the inner wall of the large flange ring to be tested.
[0050] In this embodiment, a stop block 18 is fixed to the outer end of the support rod 13. The side of the stop block 18 facing the inner wall of the large flange ring is arc-shaped, which increases the contact area with the inner wall of the large flange ring and effectively stops the large flange ring.
[0051] Furthermore, in order to protect the inner wall of the large flange ring, a rubber layer is provided on the arc-shaped surface of the abutment 18.
[0052] In this embodiment, the support mechanism 1 is provided with lifting lugs 19 to facilitate the lifting of the entire testing device by an external lifting device.
[0053] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
