Design and Application of Longmen Hydraulic Calibration Platform
The upper middle frame is a key structural component of excavators,but due to deformation caused by welding,the flatness of the bottom plane of the middle frame has always been difficult to ensure.The company has been using high-temperature flame method for thermal correction,but flame correction is time-consuming,laborious,and inefficient.To solve this problem,a movable gantry hydraulic calibration platform is designed and manufactured based on hydraulic presses,mainly including gantry frames,platforms,hydraulic cylinders,etc.Hydraulic mechanical calibration is used instead of flame calibration.And a series of bottom planes of the upper middle frame were calibrated,and the results showed that the gantry hydraulic calibration platform can quickly and effectively calibrate the bottom plane of the upper middle frame and ensure its plane size.The correctness of the design of the gantry hydraulic correction platform has been proven,and the research results show that the gantry hydraulic correction platform can effectively improve work efficiency,reduce costs,and ensure product quality by correcting the bottom plane of the upper middle frame.
