The invention discloses an
assembly device of an inner end joint and a sealing sleeve cover. A cylinder body of a
hydraulic cylinder is fixed to a
workbench connecting board A and a
piston rod of the
hydraulic cylinder is fixed to a connecting board B; a guiding post is fixed between a
workbench and the connecting board A and penetrates through a sliding board; a connecting rod is fixed between the connecting board B and the sliding board; a press fitting and air inflating
assembly is fixed to the center of the sliding board, the lower end of the press fitting and air inflating
assembly is provided with an upper pressing head, and the center of the press fitting and air inflating assembly is provided with a vertically-communicated ventilation hole; two
grinding wheels of a
grinding wheel assembly can be expanded and clamped on a large-
diameter outer circle of the sealing sleeve cover; a locating and rotating assembly comprises a CG joint locating base, a main shaft and a power mechanism; a CG joint is fixed to the CG joint locating base, the CG joint locating base is fixed to the main shaft, and the power mechanism drives the main shaft to rotate. According to the assembly device of the inner end joint and the sealing sleeve cover, assembly,
grinding and seepage detection of the CG joint and the sealing sleeve cover are achieved on the same assembly device, the assembly reliability is high, accuracy is high, grinding is even, force is appropriate, the reworking rate is low, the production efficiency is high, and the labor intensity of a worker is greatly relieved.
