The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The present invention provides a polishing device for metal surface treatment. Figure 1-Figure 6 As shown, the polishing device for metal surface treatment comprises:

[0039] A main body 100, wherein a sliding area is provided inside the main body 100, and the sliding area is arranged horizontally;

[0040] A back plate assembly 200 and a floating plate assembly 300, wherein the floating plate assembly 300 and the back plate assembly 200 are arranged perpendicular to the ground, the back plate assembly 200 is arranged at one end of the sliding area, the floating plate assembly 300 is elastically connected to the back plate assembly 200, and the floating plate assembly 300 is used to load the metal plate 500;

[0041] The polishing unit 400 slides in the sliding area. During the processing, the floating plate assembly 300 drives the metal plate 500 to approach the polishing unit 400.

[0042] In the present application, the main body is a box-type structure, and a sliding area is opened inside to arrange related equipment; a limiting guide rail is provided in the sliding area, and the floating plate assembly 300 and the polishing unit 400 both slide linearly along the limiting guide rail; a hydraulic push rod module is provided on the side of the sliding area away from the back plate assembly 200, and the hydraulic push rod module will push the polishing unit 400 to abut against the floating plate assembly 300 during the processing. Since an elastic connecting rod 220 is provided between the floating plate assembly 300 and the back plate assembly 200, the floating plate assembly 300 will be continuously pushed toward the polishing unit 400 during the polishing process;

[0043] The floating plate assembly 300 is provided with a clamping plate 340, and the metal plate 500 is vertically arranged between the clamping plates 340. The arrangement direction of the elastic connecting rod 220 is perpendicular to the gravity direction of the metal plate 500, and does not need to bear the gravity of the metal plate 500. During the processing, the metal plate 500 mainly relies on the clamping plate 340 to maintain gravity support, and the elastic connecting rod 220 mainly bears the reset function, reducing the pressure of gravity on the elastic connecting rod 220, which can effectively extend the service life of the elastic connecting rod 220;

[0044] During the processing of the polishing unit 400, a cushion block 420 is disposed on the polishing unit 400, and a stopper assembly 330 is disposed on the floating plate assembly 300. During processing, the polishing unit 400 will first touch the surface to be processed of the metal plate 500. Since the polishing unit 400 will gradually process different areas of the metal plate 500 during the processing, the stopper assembly 330 will contact the polishing unit 400 instead of the metal plate 500. The presence of the stopper assembly 330 helps the polishing unit 400 to process a smooth surface on the metal plate 500.

[0045] As the processing progresses, different areas of the metal plate 500 are gradually processed. At this time, the stopper assembly 330 replaces the surface to be processed of the metal plate 500 to contact the polishing unit 400. When the polishing unit 400 cannot contact the metal plate 500, it indicates that the processing surface of the metal plate 500 has been processed into a smooth mirror surface by the polishing unit 400, and there is no protruding part.

[0046] The working principle of the present application is that the metal plate 500 is first loaded on the floating plate assembly 300, and the polishing unit 400 is pushed to a specified position by a hydraulic push rod module as needed. The specified position selection generally causes the floating plate assembly 300 to be pushed toward the back plate assembly 200 by a certain distance in advance. At this time, the polishing unit 400 is in contact with the surface to be processed of the metal plate 500, and the elastic connecting rod 220 is in a compressed state at this time, and the limit assembly 330 is adjusted not to contact the polishing unit 400; as the processing progresses, the surface of the metal plate 500 is polished smooth, and at this time, the floating plate There will be a gap between the assembly 300 and the polishing unit 400, and the gap will be filled immediately under the action of the elastic connecting rod 220 until the limiting assembly 330 touches the polishing unit 400. When the limiting assembly 330 touches the polishing unit 400, it means that the polishing unit 400 can no longer completely contact the metal plate 500. Only when the metal plate 500 can no longer completely contact the polishing unit 400, the limiting assembly 330 can replace the metal plate 500 to contact the polishing unit 400. The limiting assembly 330 helps the polishing unit 400 to process a smooth surface on the metal plate 500.
