The technical scheme combines the detailed description of the embodiments with the drawings. As shown in fig. 1 and 2, in a processing device for a cavity surface in a guide rail housing, a support 4 is fixed at the bottom on a sliding platform 3, a sleeve 5 is horizontally fixed at the top, a rotating shaft 6 is installed in the sleeve 5 through a bearing 5-1, 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 wall of the sleeve 5 and is installed on the commutator 5-2, one end of the rotating shaft 6 penetrating out of the sleeve 5 is fixedly connected with a main rotating shaft 7 through a coupler, the main rotating shaft 7 is installed on a turntable 14, one end of the sleeve 5 close to the cutter 8 penetrates through a guider 15 and then is horizontally and fixedly connected with a positioning rod 9, and the guider 15 is fixed on a machine tool main body 1. The guide rail shell 13 is horizontally fixed through a vice 11 and is fastened on the machine tool main machine 1 through a pressure plate 12, a through hole is arranged on the guide rail shell 13, the positioning device 10 is fastened on the guide rail shell 13 in an inverted mode, a positioning ring 10-4 on the positioning device penetrates through the through hole and is located in the center of an inner cavity of the guide rail shell 13, and the positioning rod 9 penetrates through the positioning ring 10-4.

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 bottom of the support 4 is fixed on the sliding platform 3, the sleeve 5, the rotating shaft 6, the main rotating shaft 7, the cutter 8 and the positioning rod 9 can move together by moving the sliding platform 3, and the cutter feeding and retracting functions of the cutter 8 are realized. The rotary table 14 drives 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.

As shown in fig. 3, the guide 15 includes a gantry-shaped guide frame 15-1, and guide screws 15-2 are vertically provided on the upper surface and left and right sides of the guide frame 15-1, and the three guide screws 15-2 are respectively in contact with the upper surface and left and right sides of the sleeve 5. Because the sleeve 5 is long, the three guide screws 15-2 play a role of guiding during the moving process, and prevent the offset phenomenon.

As shown in fig. 4 and 5, the positioning device 10 includes a base 10-1, a positioning ring 10-4 is vertically fixed at the center of the upper surface of the base 10-1, four corners of the upper surface are provided with protrusions 10-2, a fastening screw 10-3 is provided at the same side of two pairs of protrusions 10-2, and two cushion blocks 10-5 are fixed on the base 10-1 at two sides of the positioning ring 10-4.
