Track shoes are load-bearing parts exposed to complex cyclic stress, with large bolts and high quantities. Leetx high-precision servo electric tightening prevents missed and over-tightening while maintaining full traceability.
The tube press-fitting process for construction machinery powertrains must meet requirements for joint reliability, assembly consistency and long-term sealing under heavy-duty operating conditions. These tubes carry media such as oil, fluids and gases, so press-in force, depth, speed and force-holding time must be precisely controlled to ensure a stable fit and avoid skewed insertion, deformation or sealing failure.
Frame subassembly involves mixed, irregular parts and very long bolts with spatial interference and demanding hole alignment. Leetx intelligent tightening with 3D vision guidance and a high-inertia assist arm improves positioning, torque application, and angle control.
Large high-strength bolts inside transmissions and drive axles can cause housing distortion, seal failure, or gear-mesh noise if not controlled. Leetx high-torque closed-loop control and multi-spindle synchronization help each bolt reach the required yield-point tightening condition.
Excavator hydraulic lines and engine intake/exhaust systems are typical soft-joint applications where hose elasticity can cause torque decay. Leetx dynamic torque compensation and step-tightening strategies control the release of elastic energy.
The oil-seal press-fitting process for hydraulic oil pumps must ensure coaxiality, press-in depth and seal-lip integrity to meet sealing-reliability requirements under high-pressure, high-frequency and long-duty operating conditions. Oil seals deform easily and are highly sensitive to assembly quality, so press-in force, speed, end position and the force-holding process must be precisely controlled to avoid skewed insertion
