In this embodiment, the pressurizing mechanism 300 can specifically be selected as a cylinder.

[0047] Specifically, the machine frame 100 is provided with a linear guide rail 110 in the vertical direction. A slider 411 is provided at a position corresponding to the linear guide rail 110 on the side of the connecting frame 410, and the slider 411 is slidably connected to the linear guide rail 110.

The multiple grinding mechanisms 400 are arranged side by side at intervals to simultaneously grind multiple pipelines to be ground arranged at intervals along the side-by-side arrangement direction of the multiple grinding mechanisms 400, thereby improving the grinding processing efficiency of the pipelines to be ground.

[0053] Preferably, the grinding device includes a plurality of pressing mechanisms 300 and a plurality of grinding mechanisms 400. The pressing mechanisms 300 correspond to the grinding mechanisms 400 one by one. The plurality of grinding mechanisms 400 are arranged at intervals along the length direction of the equipment guide rail on the top of the frame 100. The granularities of the grinding blocks 422 of the plurality of grinding mechanisms 400 are different, and the plurality of pressing mechanisms 300 can act separately. In this embodiment, two grinding mechanisms 400 are provided corresponding to the same pipe to be ground. The granularity of the grinding block 422 of one of the two grinding mechanisms 400 is coarser and can perform the rough grinding process of the pipe to be ground. The granularity of the grinding block 422 of the other grinding mechanism 400 is finer and can perform the fine grinding process of the pipe to be ground.

[0054] The use process of the grinding device provided in this embodiment is as follows:

[0055] First, the pipe to be ground is clamped onto the equipment guide rail, and the rotation motor is started to drive the pipe to be ground to rotate around its own axis.

[0056] Then, through the downward pressure of the pressing mechanism 300, first drive the grinding mechanism 400 with coarser granularity to press tightly on the pipe to be ground, and adjust the grinding quality by adjusting the pressure of the pressing mechanism 300.

[0057] Then, the walking drive motor 210 drives the frame 100 to reciprocate along the length direction of the equipment guide rail relative to the pipe to be ground, so that the grinding mechanism 400 with coarser granularity reciprocally grinds the pipe to be ground. In this process, the number of walking rounds is controlled by a program, and then the grinding amount is adjusted.

[0058] Then, after reaching the grinding amount, lift this pressing mechanism 300, and control the pressing mechanism 300 corresponding to the grinding mechanism 400 with finer granularity to act, drive the grinding block 422 of the grinding mechanism 400 with finer granularity to press tightly on the pipe to be ground, and adjust the grinding quality by adjusting the pressure of the pressing mechanism 300.

[0059] Then, the walking drive motor 210 drives the frame 100 to reciprocate along the length direction of the equipment guide rail relative to the pipe to be ground, so that the grinding mechanism 400 with finer granularity reciprocally grinds the pipe to be ground until the rough grinding marks on the circumferential part of the pipe to be ground are polished smoothly.

[0060] Finally, after finishing the grinding, turn off the rotation motors at both ends of the equipment guide rail, stop the pressing mechanism 300, and take out the product to complete the grinding.

[0061] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model.
