Embodiment 1
[0052] In this embodiment, the surface finishing of the large-diameter pipe 10 of a titanium alloy material used in a space shuttle is taken as an example, as figure 1 As shown, in order to clarify the direction relationship, the xyz rectangular coordinate system with the z-axis direction as the height extension direction of the large-diameter pipe 10 is set as required, combined below Figure 1 to Figure 6 Illustrate the large-caliber pipe material surface finishing equipment of the present invention, it comprises:
[0053] The frame body 20 includes a base 21, and a support frame 22 connected to the top of the base 21 in parallel and at intervals. In this embodiment, the base 21 and the support frame 22 are vertically arranged between the two through a plurality of struts 23 connected as a whole, but not limited to the pole 23;
[0054] The pipe driving device 30 includes a first drive motor 31 fixed to the base 21, a first rotary chuck 32 connected to the first drive motor...
Embodiment 2
[0068] Different from Example 1, as figure 1 with Figure 5 As shown, the support frame 22 of the frame body 20 of the large-diameter pipe surface finishing equipment in this embodiment includes a pair of parallel and spaced guide rails 1, and the pipe driving device 30 also includes a slide table 33, a screw rod 1, a third Drive motor 56 and telescopic connecting rod 36, slide table one 33 buckle on guide rail one and can slide along guide rail one, the third drive motor 56 is connected in guide rail one end, screw mandrel one is arranged along guide rail one extension direction, screw mandrel one One end of one end is connected with the third drive motor 56, the external thread of the screw rod one matches the internal thread of the slide table one 33; the hydraulic cylinder 34 is connected to the top of the slide table one 33, and the second rotary chuck 35 is located at the bottom of the slide table one 33 It is connected with the hydraulic cylinder 34 through the telesco...
Embodiment 3
[0071] The difference from Example 2 is that, as figure 1 with Image 6 As shown, the large-diameter pipe surface finishing equipment in this embodiment also includes a pipe supply mechanism 60, and the pipe supply mechanism 60 includes a pair of guide rails 2 61, slide table 2 63, fourth drive motor 62, and third Limit sensor 68, screw mandrel 2, pipe chuck 64, cylinder support 65, cylinder 66 and arc jaw 67, a pair of guide rail 2 61 is arranged along the length direction of base 21 and fixed on its end, slide table 2 63 is embedded in the second guide rail 61 and can slide along the second guide rail 61. The fourth driving motor 62 is installed on the end of the second guide rail 61. The second screw rod is arranged along the extending direction of the second guide rail 61. One end of the second screw rod is connected to the fourth drive motor 62 , the external thread of screw rod 2 matches the internal thread of slide table 2 63, the pipe fitting chuck 64 is arranged on t...
