Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, in particular to a clamping structure for metal surface treatment. Background Art

[0002] Metal surface treatment is to increase the strength of the surface of metal parts, improve the corrosion resistance, wear resistance, oxidation resistance, aesthetics and other properties of the metal parts, thereby improving the strength and life of the metal parts.

[0003] After searching, the Chinese patent with announcement number CN221247555U discloses a metal surface treatment clamping mechanism, including: a clamping table, threaded blocks are installed on both sides of the top of the clamping table, screws are installed on the threaded blocks through thread rotation, and moving blocks are rotatably installed on the sides where the two screws are close to each other, the guide rods are slidably installed, and a flipping mechanism for flipping the metal part is provided on the side of the moving block away from the threaded block, and a supporting mechanism for supporting the metal part is provided below the flipping mechanism. Through the setting of the flipping mechanism, after welding one side, the knob is turned to rotate the adjusting screw rod, driving the two auxiliary clamps to clamp and fix the two ends of the metal part, thereby improving the stability of the metal part during flipping, and then the two flipping motors rotate at the same time to flip the metal part 180 degrees so that the other side faces up, which is convenient for the staff to weld. Compared with the manual flipping in the comparative document, the welding efficiency is improved.

[0004] The inventor has found that the above-mentioned technology achieves clamping of metal parts by adjusting the screw rod to drive the auxiliary clamping plate, which is only suitable for clamping regular workpieces. It is not stable enough for clamping cylindrical or special-shaped products. At the same time, by adding a supporting mechanism, when supporting products that do not require flipping and welding, it is necessary to always connect the supporting shaft in the supporting mechanism to the external driving device during use to ensure the stability of the supporting mechanism. However, this leads to the need to add additional driving equipment, which is not convenient to use. Therefore, the utility model proposes a clamping structure for metal surface treatment.
