Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of precision casting correction, more particularly to a floating correction device with a pressing function. BACKGROUND

[0002] In the aviation and aerospace industries, precision casting technology is widely used due to the high requirements for the weight of parts. The machining of castings is based on a relatively accurate blank surface as the initial reference. After the reference is corrected to meet certain requirements, other parts are machined to form a new and accurate machining reference. Finally, the product is formed. Due to different casting deviations, the usual correction amount does not exceed one millimeter. The higher the casting precision, the smaller the correction amount.

[0003] The correction method is to check the blank reference surface with a dial gauge, detect the highest and lowest points, and then use the middle value as the standard to adjust the initial position of the workpiece. Since the adjustment amount during the correction process is very small, usually not exceeding one millimeter, and the adjustment amount of most workpieces is within the range of 0.4-0.7 millimeters, the correction method is to add shims between the workpiece and the mating surface of the machine tool or fixture. The thickness of the shim is standard and forms a series (0.02, 0.04, 0.05…0.1, 0.2, 0.5, etc.). By combining shims, the required adjustment amount is formed. Since the adjustment surface of the workpiece is also the blank surface, the adjustment amount of each adjustment point is different, and each adjustment point is a pressing point to ensure that the workpiece is not deformed and the stability of the machining process.

[0004] The adjustment is a very meticulous process. The workpiece is a whole, and each point needs to be lifted. For heavier workpieces, it is not easy to move each time. The adjustment shim is very thin and easily deformed, leading to distortion of the calibrated thickness. Under the weight of the workpiece, part of the thickness is restored, but it is not the calibrated thickness, which also leads to distortion of the adjustment data. Finally, in the completely pressed state of the workpiece, the adjustment result displayed is also inaccurate. In the case of data distortion and large deviation, the workpiece needs to be adjusted again.

[0005] Since the pressing device of the workpiece is close to the adjustment point, the operation of adding or removing adjustment shims has an impact on the adjustment process. Only after the adjustment is completed can the assembly be performed, and the pressing work is completed, which is low in efficiency.

[0006] Therefore, there is an urgent need for a floating correction device with a pressing function to solve the above problems. SUMMARY
