The invention relates to the technical field of slewing bearing production, and discloses an automatic measuring and assembling table of a slewing bearing. The automatic measuring and assembling tablecomprises a transverse plate and measuring equipment, wherein supporting columns are fixedly connected to the four corners of the lower end of the transverse plate, a T-shaped sliding groove is formed in the upper end of the transverse plate, a clamping mechanism is arranged in the T-shaped sliding groove, the right side of the upper end of the transverse plate is fixedly connected with a fixingrod, the rod wall of the fixing rod is connected with a transverse rod through a rectangular through hole transverse slide groove, the right side of the upper end of the transverse rod is connected with a transmission mechanism, the left side of the upper end of the transverse plate is connected with a mounting rod with an L-shaped structure in a sliding mode through a round hole, and one side ofthe horizontal part of the mounting rod is fixedly connected with the measuring equipment. The automatic measuring and assembling table can clamp the slewing bearings with different types and tooth surfaces, is convenient to use by workers, can measure the clearance of the slewing bearing in a rotary state, and improves the detection speed.
