The lower ends of the stand legs 14 are provided with ground feet 15 so as to fix the rack 1 on the bottom surface and avoid collision and displacement. One side edge of the working plane 11 of the table frame 1 is provided with an opening 12, and the opening 12 is arranged on the center line of the working plane 11. The opening 12 is arranged, an operator can observe the assembly process of the piston ring through the opening 12, and the assembly process can be found in time and processed correctly when errors exist. The turntable mechanism is arranged on a reinforcing frame 13 of the gantry 1. Specifically, the turntable mechanism comprises a turntable 2, a guide wheel 25 and an annular guide rail 21, and the diameter of the turntable 2 is the same as that of the annular guide rail 21. And at least 2 piston ring assembling machines with different specifications are uniformly distributed on the upper surface of the rotary table 2 so as to adapt to piston assembling piston rings with different sizes. Referring to fig. 8-9, the annular guide rail 21 is provided with an annular guide rail groove 24 and a central weight-removing hole 22. The turntable 2 is arranged above the annular guide rail 21 through the guide wheels 25, the 6 guide wheels are annular and are uniformly fixed on the lower surface of the turntable 2, and each guide wheel 25 falls into the annular guide rail groove 24 and moves along the stroke of the annular guide rail groove 24 so as to realize that the turntable 2 rotates around the center of the turntable. The lower surface of the annular guide rail 21 is welded and fixed to the reinforcing frame 13 of the gantry 1. A plurality of piston ring assembling machines with different models are fixed on the turntable 2, so that the assembling requirements of the piston models with different sizes are met. During assembly, an operator stands in front of the opening 12 of the working plane 11 of the rack 1, manually rotates the turntable 2 according to the type of the piston, rotates the piston ring assembly machine according with the size of the piston to be right below the opening 12, fixes the turntable 2 by the locking device, and limits the rotation of the turntable 2.
