Multi-Angle Hydraulic Rotary Positioner, Lock at Any Desired Angle for Welding, Assembly and Grinding

The base, support frame and tilting beam are constructed from thickened industrial steel plates and heavy-duty profiles through full-penetration welding. After welding, the entire structure undergoes high-temperature stress-relief annealing to eliminate internal welding stress and structural fatigue.

All key installation and working reference surfaces are precisely machined by CNC equipment. The frame delivers ultra-high rigidity, strong compression resistance and excellent anti-deformation performance, maintaining stable operation without shaking, vibration or deflection during long-term full-load operation and repeated force processing such as grinding and bolt tightening.

Equipped with a professional silent hydraulic power unit, high-pressure wear-resistant hydraulic cylinder and imported balance valve group, the equipment achieves smooth, stable stepless tilting within 0°–90°.

The hydraulic system adopts buffer start and buffer stop design, making the entire tilting process soft, uniform and shock-free, effectively protecting workpieces and fixtures from impact damage. The built-in hydraulic self-locking device stably locks any working angle — even under full workpiece load, grinding pressure and assembly torque, the table will not sink, drift or shift, ensuring zero-error positioning during precision processing.

All hydraulic pipelines and core components are fitted with dust-proof and anti-welding-spatter protective covers to suit harsh industrial workshop environments and extend service life.

The rotary table is equipped with a large-diameter heavy-duty slewing bearing offering strong load-bearing capacity, high rotation accuracy and excellent anti-overturning stability.

Driven by a frequency-conversion motor and high-precision worm gear reducer, rotation speed ranges from 0.1 rpm to 1.0 rpm with infinitely variable regulation. Rotation is uniform, stable and free of speed fluctuation and jitter.

Low-speed rotation suits fine grinding, precise deburring, uniform bolt installation and full-circle inspection; constant-speed stable rotation perfectly matches MIG, MAG, TIG and SAW automatic welding processes, ensuring uniform weld heat input, consistent penetration depth and smooth, beautiful weld formation.

The rotary table is reserved with standard T-slots for flexible installation of custom tooling, positioning fixtures and auxiliary supports. The standard four-jaw self-centering chuck supports both external clamping and internal expansion clamping modes.

It accurately and firmly fixes various pipes, flanges, elbows, ring parts and cylindrical workpieces, featuring high centering accuracy and strong anti-loosening performance. No eccentric shaking or workpiece loosening occurs during high-speed rotation and large-angle tilting, ensuring stable and consistent processing quality for batch production.

The positioner is equipped with a handheld remote control and a local fixed control box for dual operation. Operators can remotely control rotation start/stop, speed adjustment and hydraulic tilting angle switching at a safe distance, avoiding risks from high temperature, welding spatter and mechanical collision.

The equipment integrates multiple industrial safety protection functions, including hydraulic overpressure protection, motor overload protection, tilting limit protection and emergency stop protection. In case of abnormal operation or overload, the machine automatically stops to ensure personnel and equipment safety.

All transmission parts, electrical components and hydraulic interfaces adopt a fully enclosed protective structure to isolate dust, metal debris, oil stains and welding spatter. The whole machine is treated with pickling rust removal, anti-rust primer and industrial finish paint, delivering excellent corrosion resistance, wear resistance and oxidation resistance for long-term 24-hour continuous industrial operation.
