The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The technical scheme combines the detailed description of the embodiments with the drawings. As shown in fig. 1-4, a girder shell inner cavity surface processing device, a support 4 of which the bottom is fixed on a sliding platform 3, a sleeve 5 is horizontally fixed on the upper part, a rotating shaft 6 is installed in the sleeve 5 through a bearing 5-1, and a commutator 5-2 is installed at one end of the rotating shaft 6 in the sleeve 5, a cutter 8 vertically penetrates through the sleeve 5 downwards and is installed on the commutator 5-2, a tailstock 5-3 is sealed at one end of the sleeve 5 close to the cutter 8, one end of the rotating shaft 6 penetrating out of the sleeve 5 is connected and fixed with a main rotating shaft 7 through a coupler, the main rotating shaft 7 is installed on a turntable 14, and a positioning slider 9 is arranged on the outer circular surface of the sleeve 5 at a position close to the tailstock 5-3; the girder shell 13 leans against the backup plate 11 and is fastened on the positioning seat 10 by the pressure plate 12, and positioning slide ways 13-1 matched with the positioning slide blocks 9 are arranged on two sides of the inner cavity of the girder shell 13.

The machine tool main body 1 is provided with a slide way 2, the sliding platform 3 is arranged on the slide way 2 and can move freely, and the rotary table 14 is arranged on the machine tool main body 1 and is driven by a motor on the machine tool main body 1. Because the support 4 is fixed on the sliding platform 3, the sliding platform 3 moves, and the support 4, the sleeve 5, the rotating shaft 6, the main rotating shaft 7 and the cutter 8 move together, namely, the function of feeding and retracting actions is realized. The rotary disc 14 can drive the main rotating shaft 7 and the rotating shaft 6 to rotate, and drives the cutter 8 to rotate under the action of the commutator 5-2.

The number of the positioning slide ways 13-1 is four, two positioning slide ways 13-1 are respectively arranged on two sides of the inner cavity of the girder shell 13, the positioning slide ways 13-1 on the same side vertically correspond to each other, the number of the positioning slide blocks 9 is also 4, and the positions of the positioning slide blocks distributed on the outer circular surface of the sleeve 5 correspond to the positions of the four positioning slide ways 13-1.
