[0023] When positioning and clamping the workpiece, the telescopic cylinder 32 at the top will stably drive the position of the support structure 34 to rise and fall, thereby retracting and positioning the adaptive clamping components 5 at both ends of the bottom, and providing stable installation conditions for the internal structure.

[0024] The active control component 3 includes, but is not limited to, a motor control structure and a hydraulic cylinder control structure; in this embodiment, the active control component 3 preferably uses a hydraulic cylinder control structure.

[0037] The working principle of the adaptive handling fixture for heavy workpieces provided by this utility model is as follows:

[0038] When the fixture clamps and moves heavy workpieces, the overall structure is first installed using the fastening components 2 at both ends. Then, when clamping and moving the heavy workpiece, the active control component 3 at the top drives the adaptive clamping component 5 at the output end. Under continuous drive, the adaptive clamping component 5 is limited by the adaptive limit component 7. Subsequently, the unfolded adaptive clamping component 5 becomes vertical to position and clamp the workpiece. When clamping and positioning different types of workpieces, the telescopic adjustment components 4 at both ends automatically adjust the position of the adaptive clamping component 5 to clamp and move different types of workpieces. After being moved to the appropriate position, the friction unloading components 6 at both ends of the inner wall can be driven to easily unload the workpiece.

[0039] Compared with related technologies, the adaptive handling fixture for heavy workpieces provided by this utility model has the following advantages:

[0040] When clamping and transporting heavy workpieces, to improve the ease of use and versatility of the fixture, the adaptive clamping component 5 and the telescopic adjustment component 4 work together. Driven by the active control component 3, the adaptive clamping component 5 automatically positions itself according to the shape and size differences of the heavy workpiece, thus automatically adjusting the clamping position and avoiding the cumbersome process of changing fixtures when clamping different types of workpieces. Simultaneously, after the workpiece is positioned and clamped, the friction unloading component 6 on the inner wall allows for sliding unloading, enabling the workpiece to quickly detach from the fixture.
