Technical Field

[0022] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3As shown, an automatic polishing machine for stainless steel pipes comprises a base 1 and an active roller 2 and a polishing roller 3 arranged on the base 1, and a steel pipe transfer device is also arranged on the base 1 between the active roller 2 and the polishing roller 3;

[0024] The steel pipe transfer device comprises a base 4 connected to the base 1 by lifting, a trustee mechanism 5 arranged on the base 4, and a driving mechanism that drives the steel pipe 13 to move along the base 4;

[0025] The trusteeship mechanism 5 includes two support arms 6 and rotating wheels 7 rotatably connected to the top ends of the two support arms 6, the bottom ends of the two support arms 6 are swingably connected to the base 4, and a spring 8 is also connected between the middle parts of the two support arms 6. The base 4 is also provided with limit platforms 9 corresponding to the two support arms 6, so that the two support arms 6 always maintain a closing trend, and the two limit platforms 9 limit the opening range of the two support arms 6 and provide support for the trusteeship mechanism 5 when supporting the steel pipe 13;

[0026] The driving mechanism includes a mounting seat 10 , a driving wheel 11 rotatably connected to the mounting seat 10 , and a first driving motor 12 driving the driving wheel 11 to rotate.

[0027] In another embodiment, the mounting seat 10 is telescopically connected to the base 4 via a spring and a guide rod, so that the driving mechanism can self-extend and self-adaptively abut the steel pipe 13, and finally smoothly drive the steel pipe 13 to move.

[0028] In another embodiment, if Figure 2 As shown, when the steel pipe 13 is not supported, the base 4 is in a lowered state, the two supporting arms 6 of the hosting mechanism 5 are in a closed state, and the rotating wheel 7 is located below the active roller 2 and the polishing roller 3 to avoid affecting the rotation and polishing of the steel pipe 13.

[0029] In another embodiment, if Figure 3 As shown, when the steel pipe 13 is supported, the base 4 is in a raised state, the rotating wheel 7 of the hosting mechanism 5 is located above the active roller 2 and the polishing roller 3, the two rotating wheels 7 respectively abut against the two sides of the steel pipe 13 and press the two supporting arms 6 to open, the outer sides of the two supporting arms 6 respectively abut against the corresponding limit platforms 9, and the driving wheel 11 of the driving mechanism abuts against the bottom of the steel pipe 13.

[0030] The working principle of the above structure is: when the steel pipe 13 is input into the automatic polishing machine along the conveying mechanism, the steel pipe transfer device rises and transfers the steel pipe 13 to the steel pipe transfer device. At this time, the trusteeship mechanism 5 of the steel pipe transfer device supports the steel pipe 13. Under the action of the deadweight of the steel pipe 13, the two support arms 6 gradually open to support the steel pipe 13 more stably; the driving mechanism drives the steel pipe 13 to continue to move forward until the steel pipe 13 is moved to a suitable position between the active roller 2 and the polishing roller 3, and the steel pipe transfer device is lowered; as the steel pipe transfer device descends, the two support arms 6 and the rotating wheel 7 respectively abut the active roller 2 and the polishing roller 3, and gradually close along the gap between them, and smoothly transfer the steel pipe 13 to the active roller 2 and the polishing roller 3. When the steel pipe transfer device is completely lowered, the two support arms 6 are closed under the action of the spring 8; when the grinding of the steel pipe 13 is completed, the steel pipe transfer device repeats the above action to output the steel pipe 13 between the active roller 2 and the polishing roller 3.

[0031] The beneficial effects of the above structure are: simple structure, the steel pipe transfer device is integrated between the active roller 2 and the polishing roller 3, does not take up too much additional installation space, and can automatically input and output the steel pipe 13 into and out of the polishing machine without causing damage to the steel pipe 13, thereby improving the degree of automation of the polishing machine.

[0032] Specifically, Figure 1 As shown, the driving wheel 11 has an arc groove in the middle, and the driving wheel 11 is longitudinally rotatably connected to the mounting seat 10.

[0033] In another embodiment, if Figure 1 As shown, a second driving motor is provided on the outer side of one end of the base 1, and the second driving motor drives the active roller 2 to rotate horizontally. The active roller 2 drives the polished steel pipe 13 to rotate, so that the steel pipe 13 abuts against the polishing roller for polishing.

[0034] In another embodiment, if Figure 1 As shown, the base 4 extends along the length direction of the base 1 .

[0035] In another embodiment, in combination Figure 1-3 As shown, the rotating wheel 7 is longitudinally rotatably connected to the end of the supporting arm 6.

[0036] In another embodiment, if Figure 1 As shown, there are multiple groups of the trusteeship mechanisms 5, and each group of trusteeship mechanisms 5 is arranged on the base 4 at equal distances to more stably support the steel pipe 13.

[0037] In another embodiment, if Figure 1 As shown, there are two groups of driving mechanisms, which are respectively arranged at two ends of the base 4 to facilitate the steel pipe 13 to enter and exit the polishing machine.
