[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous high-precision clamps, when encountering curved parts, multiple disassembly and assembly operations are required to adjust the angle, which makes the clamping easy to slip and damage the parts, reducing the overall clamping effect. The difference is that the first-level containment limit assembly is a multi-stage arrangement of multiple groups of linear arrangements, which can perform parallel and sequential multi-stage positioning and clamping operations according to different curved parts. The pressure-bearing assembly can support the overall stability and increase the pressure-bearing strength. The first-level containment limit assembly facilitates the circumferential sliding of the second-level clamping adjustment assembly to perform the first-level containment limit. The second-level clamping adjustment assembly can slide circumferentially inside the first-level containment limit assembly, and the diameter of the curved part can be locked and clamped in both directions. The three-level guide locking assembly is distributed on the same surface of the first-level containment limit assembly and the second-level clamping adjustment assembly. The locking adjustment and guide sliding control adjustment can maintain high-precision and stable clamping control, perform sequential multi-stage adjustment operations, and improve the overall locking control operation.

[0014] 2. When operating, use the mounting hole to install the corresponding auxiliary positioning structure so that the second half-ring clamp can better position the curved part. The telescopic cylinder drives the telescopic push rod to drive the second half-ring clamp to move toward the first half-ring clamp to perform clamping and positioning. The vibration sensors on both sides sense the displacement change state. The driving module drives the first guide arc block to drive the first half-ring clamp to slide along the first arc groove. The synchronous driving module drives the second guide arc block to move along the second arc groove. The two operate synchronously. During synchronization, the telescopic spring sleeve stretches and shortens, and the first half-ring clamp is synchronously displaced along the slide rail sleeve. When reaching the corresponding position, the control cylinder drives the positioning push rod to position the locking hole so that it can perform the locking operation.
