[0023] See also Figure 1-5 The utility model provides a technical solution: a heat-treated steel strip surface polishing device, including a frame 1, a polishing machine mounting frame 2, and a waste chip tank 4. A placing table 3 is arranged in the middle of the top surface of the frame 1, and fixed plates 31 are fixedly installed on both sides of the top of the inner wall of the frame 1. A positioning plate 32 is detachably installed on the top of the placing table 3, and an electromagnet 33 is installed at equal intervals in the middle of the top surface of the positioning plate 32. A hydraulic cylinder 5 is fixedly installed at one end of the inner wall of the placing table 3;

[0024] The telescopic end of the hydraulic cylinder 5 is fixedly connected with a positioning rack 6, and the two ends of the placing platform 3 are respectively penetrated and connected with a rotating shaft, and the end of the rotating shaft is sleeved with a positioning gear 7, and the outer edge of the positioning gear 7 on the same side is meshed with the outer edge of the positioning rack 6. An electric telescopic rod 8 is installed on one side of the inner wall of the frame 1, and a scraper plate 9 is fixedly installed at the telescopic end of the electric telescopic rod 8;

[0025] The heat-treated steel strip is placed on the placement table 3, and the electromagnet 33 on the positioning plate 32 can adsorb the bottom surface of the steel strip and position it on the positioning plate 32. The polishing machine is installed on the polishing machine mounting frame 2 on the frame 1, and the surface of the heat-treated steel strip on the placement table 3 can be polished. The technical solution for polishing the surface of the heat-treated steel strip is an existing technology and will not be described in detail here.

[0026] The two sets of positioning plates 32 can be slidably engaged on the upper and lower surfaces of the placing platform 3, and the telescopic end of the hydraulic cylinder 5 can drive the positioning rack 6 to drive the positioning gears 7 at both ends of the placing platform 3, so that the placing platform 3 can be turned over in the middle of the frame 1, so that the steel belts on the two sets of positioning plates 32 can be alternately turned over to the bottom of the polishing machine mounting frame 2, so that the steel belts on the two sets of positioning plates 32 can be alternately turned over and repositioned, realizing the alternate polishing and grinding of both sides of a large number of steel belts, without stopping the machine to remove the steel belt, turning over and repositioning the operation, so that the polishing process of both sides of the steel belt is closely connected, thereby improving the surface polishing processing efficiency of the steel belt;
