This invention belongs to the field of automated
assembly technology, and specifically relates to a semi-automatic tightening device for confined spaces. It includes a power source lifting
system, an upper tooling horizontal feed
system, an upper tooling lifting
system, an upper tooling indexing and
positioning system, a tightening central system, and a bottom
support system. The power source lifting system, upper tooling horizontal feed system, upper tooling lifting system, and upper tooling indexing and
positioning system are connected sequentially from top to bottom. The tightening central system is connected to the upper tooling lifting system, and the bottom
support system is connected to the bottom of the tightening central system. The power source lifting system is used to complete the docking action of the tightening power source, the tightening central system is used to complete the tightening
power output, and the bottom
support system is used to assist the tightening central system in providing radial support. This invention features a high degree of
automation and
high motion precision, avoiding
human error and ensuring consistent tightening of all nuts.
