AI Technical Summary
The existing clamping structure has a fixed and non-adjustable shape, which cannot meet the processing requirements of oil rod heads of different diameters.
A multifunctional clamp was designed, comprising a base plate, a disassembly and assembly assembly, and a radial positioning assembly. Multi-directional positioning is achieved through adjustable docking blocks and a damping shaft. Combined with a moving assembly consisting of a drive motor and a bidirectional lead screw, stable clamping of oil rod heads of different diameters is achieved.
It achieves stable clamping of oil rod heads of different diameters, improves the flexibility and stability of clamping, and simplifies the process of clamp replacement and maintenance.
