[0013] Beneficial Effects

[0014] Compared with the prior art, the advantages of the steel pipe grinding and polishing device with adjustable outer polishing wheel position of the present invention are:

[0015] 1. On the polishing line, different polishing wheels can adjust the grinding angle of the corresponding steel pipe through the deflection mechanism. The steel pipe can be polished from multiple angles to make the surface polishing effect of the steel pipe more uniform. When scratches in the same direction need to be polished on the steel pipe, it is only necessary to unify the deflection angle of each polishing wheel, so that the applicability of the polishing line is wider.

[0017] 3. The rotary drive mechanism includes a second motor and a sleeve respectively installed on both sides of the lifting seat, and the polishing wheel is installed on the same side of the sleeve. This arrangement can make the force on both sides of the lifting seat more evenly applied, thereby extending the service life of the lifting mechanism.

The deflection mechanism 9 can drive the lifting mechanism 4 and the polishing wheel 3 to rotate within a range of 40-50° around the vertical axis relative to the translation mechanism 5. This process ensures that the polishing wheel 3 is always located in the dust cover 2.

[0028] The lifting mechanism 4 includes a lifting rail 41 and a lifting seat 42 that are slidably matched with each other, and the rotary drive mechanism 6 is installed on the lifting seat 42. The lifting rail 41 is connected to the deflection mechanism 9, and a lifting drive device connected to the lifting seat 42 is provided on the lifting rail 41.

[0029] In this embodiment, the lifting drive device includes a first motor 44 installed on the lifting track 41 . The output end of the first motor 44 is linked to a vertically arranged first screw rod 43 . The first screw rod 43 is threadedly matched with the lifting seat 42 .

[0030] The rotary drive mechanism 6 comprises a second motor 61 and a sleeve 63 respectively mounted on both sides of the lifting seat 42, and the sleeve 63 is arranged horizontally. A rotating shaft 64 is provided in the middle of the sleeve 63 to rotate with it, and the polishing wheel 3 is connected to one end of the rotating shaft 64, and the other end of the rotating shaft 64 is linked to the output end of the second motor 61 through a transmission structure 62. In this embodiment, the transmission structure comprises a matching belt and two pulleys, and the two pulleys are respectively mounted on the output end of the second motor 61 and the rotating shaft 64.

[0031] The translation mechanism 5 includes a translation guide rail 52 and a translation base 51 that slide with each other. The translation guide rail 52 is fixedly mounted on the platform 1. The translation direction of the translation base 51 is perpendicular to the axis of the steel pipe 8. The deflection mechanism 9 is installed between the lifting track 41 and the translation base 51. A translation drive device is connected between the translation base 51 and the translation guide rail 52.

[0032] The translation drive device includes a second screw rod 53, which is rotatably connected to the translation guide rail 52 and is threadedly connected to the translation base 51. One end of the second screw rod 53 is connected to a first hand wheel 54, which is rotatably connected to a bearing seat 55, and the bearing seat 55 is installed on the platform 1. By rotating the first hand wheel 54, the translation base 51 can be driven to move linearly in the horizontal direction relative to the translation guide rail 52.

The dust suction pipe 7 is connected to a dust removal port provided on one side of the dust cover 2, and the dust removal port is located on one side of the steel pipe 8. When the polishing wheel 3 polishes the steel pipe 8, dust is generated. The dust suction pipe 7 sucks away the dust in the dust cover 2 through negative pressure, thereby reducing the amount of dust floating out of the dust cover 2.

[0036] In this embodiment, a dust cover support frame 23 is provided at the bottom of the rear side of the dust cover 2. The dust cover 2 and the platform 1 are connected via the dust cover support frame 23. A gap is left between the dust cover 2 and the platform 1 for the second screw rod 53 to pass through.

[0037] On the polishing line, different polishing wheels 3 can adjust the grinding angles of their corresponding steel pipes 8 through their respective deflection mechanisms 9, so as to achieve grinding and polishing of the steel pipe 8 from multiple angles, which can make the surface polishing effect of the steel pipe 8 more uniform; and when scratches in the same direction need to be polished on the steel pipe 8, it is only necessary to unify the deflection angles of the polishing wheels 3, thereby making the polishing line more applicable.
