Description

Technical Field

[0001] This utility model relates to the field of scanning technology for oilfield drilling and production parts, specifically an adjustment device for three-dimensional scanning testing of oilfield drilling and production parts. Background Technology

[0002] Oilfield drilling and production parts are mostly irregularly shaped structures with complex curved surfaces. Their dimensional accuracy and surface integrity directly affect the safety and efficiency of drilling and production operations. 3D scanning testing is the core technical means for quality inspection and reverse engineering of such parts. During the scanning process, it is necessary to achieve precise positioning and multi-position adjustment of the parts, and at the same time ensure that the distance between the scanner and the parts is appropriate in order to fully collect complete data of the part surface. Therefore, a special adjustment device is a key supporting equipment for 3D scanning testing.

[0003] Under current technological conditions, when performing 3D scanning of oilfield drilling and production parts, a general-purpose fixture combined with a simple turntable is usually used for fixing and adjusting. The adjustment of the part's posture mostly relies on manual operation, which is not only inefficient and difficult to achieve accurate and repeatable positioning, but also cannot achieve continuous rotation control during the scanning process, affecting the integrity and accuracy of data acquisition of complex curved surfaces. Therefore, improvements are needed. Utility Model Content

[0024] This utility model provides the following technical solution:

This allows the rotating disk 245 to rotate the clamped oilfield drilling and production parts, enabling the scanner 33 to scan different positions around the oilfield drilling and production parts.

[0029] Furthermore, the inner side of the fixed frame 22 is provided with a sliding groove corresponding to the movement trajectory of the lifting plate 21, and the lifting plate 21 is slidably connected inside the sliding groove.

The limiting groove can limit the push plate 32, making the push plate 32 more stable during the lifting and lowering process.

[0035] In actual operation, when this device is used and it is necessary to perform three-dimensional scanning of oilfield drilling and production parts, the oilfield drilling and production parts are placed between two rotating disks 245. The switch of the first hydraulic cylinder 23 is turned on, so that the first hydraulic cylinder 23 pushes the lifting plate 21 to drive the rack 25 to move, so that the rack 25 can drive the rotating gear 26 to rotate, so that the rotating gear 26 can drive the front rack 25 to move, so that the two lifting plates 21 can simultaneously drive the support 247 and the rotating gear 246 to rotate, so that the rotating gear 246 can drive the rotating disk 245 to move, so that the rotating disk 245 can clamp the oilfield drilling and production parts.

Turn on the second hydraulic cylinder 31 switch to push the push plate 32 upward, which in turn moves the scanner 33, allowing it to scan the surface of the oilfield drilling and production parts. When scanning different positions of the oilfield drilling and production parts is required, turn on the servo motor 241 switch. The servo motor 241 drives the drive gear 242 to rotate via the linkage rod 243. The drive gear 242 then drives the rotating disk 245 to rotate via the rotating gear 246, allowing the rotating disk 245 to rotate the clamped oilfield drilling and production parts. This enables the scanner 33 to perform three-dimensional scanning of different positions on the periphery of the oilfield drilling and production parts. Scanner 33 model: Radian Pro.
