Description

It has very high technical requirements in terms of structural complexity, parts manufacturing accuracy, and assembly and debugging accuracy. Figure 6 As shown, when assembling the swing head unit, the S spindle 8 needs to be installed in the front and rear rotary cavities 9 at the lower end of the swing head box with its rotation and positioning mechanism. The entire swing head unit weighs nearly 500KG and is equipped with multiple precision parts inside. During the assembly process, the swing head box needs to be flipped multiple times according to the assembly process sequence for easy installation. The shape of the swing head box is relatively irregular, with thin wall thickness, high precision and easy deformation.

[0003] like Figure 7 As shown in the existing assembly process diagram of the swing head box, a crane, a lifting beam 11, a lifting ring 10 and other lifting equipment are used, and more than two people are required to work together to flip the front and rear rotating cavities of the swing head box to the horizontal upward direction, so as to facilitate the installation of the rotating and positioning mechanism and the S spindle and other precision parts. The whole assembly process requires the swing head box to be repeatedly flipped many times according to the assembly process flow, which has the problems of difficulty in flipping, low assembly efficiency, and quality risks caused by uneven force on the box during the flipping process.

[0004] To sum up, there are many inconveniences in the existing assembly and flipping processes of the swing head, mainly because the swing head unit is heavy and has an irregular shape, which makes assembly and flipping difficult and the assembly efficiency is low; at the same time, because the swing head unit has a compact structure, the wall thickness of the swing head box is thin, and the size and shape and position tolerance accuracy requirements of the swing head box are high, the box is easily deformed due to uneven force during the flipping process, causing quality risks and other abnormal conditions.

[0005] In view of the above-mentioned assembly process characteristics of the swing head unit, it is necessary to design a swing head assembly and flipping workbench to make the swing head assembly process and flipping process simple, stable and reliable, and have the functions of assembly and adjustment and trial run.
