[0024] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not intended to limit the present application.

[0025] Embodiment one

[0027] The floating force limiting position triangular abrasive belt polishing equipment disclosed by the embodiment can drive the triangular mechanism to move on the surface to be processed 500 through the moving mechanism 100. In this process, the protective dust collection mechanism 300 can concentrate and adsorb the debris and dregs generated in the polishing process, and can also stop the sparks and iron filings generated in the polishing process, thereby improving the cleanliness and safety during use of the equipment. At the same time, the hard limiting mechanism 400 can fundamentally avoid the phenomenon of over-polishing, thereby improving the polishing quality and reducing the scrap rate. Compared with conventional polishing equipment, the application has the advantages of strong controllability, clean operation process, high processing quality, good processing safety, wide application range and the like, and provides a new idea for the structural development of polishing equipment.

[0028] participate Figure 1 In the embodiment, the moving mechanism 100 is preferably an electrically controlled floating mechanical arm, which is used to drive the triangular polishing mechanism 200 to move along the surface to be processed 500 to realize the moving polishing process of the surface to be processed 500. The triangular polishing mechanism 200 is used for main polishing processing. The protective dust collection mechanism 300 is used to stop sparks and debris during polishing, and simultaneously adsorbs and recycles the debris generated after polishing. The hard limiting mechanism 400 is used to limit the actual working height of the triangular polishing mechanism 200, so that the polishing quality is uniform and stable. In different embodiments, the moving mechanism 100 can also be configured as other structures with connection and driving functions, and the utility model does not make specific limitations thereon.

[0029] see Figure 2 In the embodiment, the triangular polishing mechanism 200 includes a mounting frame 210, three grinding wheels 220 and a polishing belt 230. The mounting frame 210 is detachably connected with the moving mechanism 100. The three grinding wheels 220 are connected to the mounting frame 210 and are arranged as three vertices of an equilateral triangle. The polishing belt 230 is sleeved on the three grinding wheels 220. Based on the above structure, the polishing belt 230 can receive uniform and stable thrust, thereby ensuring stable connection and stable polishing quality during rotary polishing, and prolonging the service life of the polishing belt 230, reducing the replacement frequency and cost of the equipment.

[0030] In the embodiment, the protective dust collection mechanism 300 is detachably connected with the triangular polishing mechanism 200 through a plurality of detachable parts 330. The detachable parts 330 are arranged on the periphery of the protective frame 310 and are preferably buckles. In the embodiment, the opposite sides of the protective frame 310 in the thickness direction are both in communication with the outside, so that the working end of the triangular polishing mechanism 200 can pass through. The protective frame 310 plays a main splash stopping role. The dust collection pipeline 320 is externally connected with an adsorption device to adsorb and recycle the debris generated in the protective pipe, thereby realizing the effect of "polishing, protecting and cleaning simultaneously".

Any side plate 311 is provided with a supporting groove 314, and the working end of the triangular polishing mechanism 200 is embedded and supported in the supporting groove 314. Specifically, the triangular polishing mechanism 200 is arranged in the protective frame 310 from top to bottom during assembly. Therefore, the supporting groove 314 in the embodiment is recessed downward from the top of the corresponding side plate 311, and the recessed shape is matched with the corresponding triangular polishing mechanism 200.

Specifically, when a longer dust suction pipe is needed, the extension length thereof can be increased by connecting the extension pipe 323; when the extension pipe 323 is not needed, it can be detached, thereby improving the use flexibility of the device. Further, the connecting piece 322 in the embodiment is preferably a bolt, the docking pipe 325 is preferably a high-temperature-resistant steel structure, and the extension pipe 323 and the flexible pipe 321 are configured to have higher flexibility and lower cost, so that the heat dissipation isolating piece 324 needs to be arranged to reduce the internal temperature of the dust suction pipe 320 during the dust suction process, thereby forming heat insulation protection for the extension pipe 323 and the flexible pipe 321, and improving the safety during operation. The specific type of the heat dissipation isolating piece 325 is not limited in the utility model.

[0034] Further, the docking pipe 325 in the embodiment comprises an expansion part and an extension part, wherein the extension part is in communication with the heat dissipation isolating piece 324 and extends in the same direction as the extension pipe 323, and the opening inner diameter of the expansion part gradually increases from the heat dissipation isolating piece 324 to the protective frame 310, so as to increase the dust suction range of the dust suction pipe 320.
