The connecting plate 12 is in the shape of an inverted “concave” plate. The connecting plate 12 is fixedly connected to the upper sides of the two mounting plates 11, so as to realize the connection between the two mounting plates 11.

[0036] The limiting plate 2 is mounted on the connecting plate 12 and located between the two mounting plates 11. Therefore, the two mounting plates 11, the limiting plate 2 and the rack form a limiting groove 3. The limiting groove 3 is used for limiting the passing of the metal workpiece.

[0037] In actual application, when the metal workpiece is located in the limiting groove 3, the limiting plate 2 abuts against the upper side of the metal workpiece. Therefore, the lower side of the metal workpiece is in contact with the polishing belt. The polishing belt driven by the transmission mechanism polishes the lower side of the metal workpiece. Then, the next metal workpiece is put into the limiting groove 3. The metal workpiece polished is pushed out. Thus, the polishing of the surface of the metal workpiece is completed. The operation is simple and convenient. Therefore, the polishing of the surface of the metal workpiece is facilitated.

[0038] In some embodiments, the number of the connecting plates 12 is two. The two connecting plates 12 are arranged in the length direction of the mounting plates 11 at intervals. Therefore, the stability of the connection between the two mounting plates 11 is improved. Meanwhile, the stability of the connection between the limiting plate 2 and the mounting plates 11 is also improved.

[0039] In some embodiments, the limiting seat 1 further comprises connecting studs 13, first connecting nuts 14 and second connecting nuts 15, the number of the connecting studs 13, the first connecting nuts 14 and the second connecting nuts 15 is the same as the number of the connecting plates 12.

By rotating the first connecting nut 14 and the second connecting nut 15, the height of the limiting plate 2 can be adjusted, so that the limiting plate 2 can abut the metal workpiece more stably and accurately, so as to improve the polishing effect of the surface of the metal workpiece, and the limiting device can be applied to metal workpieces of different thicknesses, so as to improve the applicability of the limiting device.

[0040] In some embodiments, the limiting seat 1 further comprises a gasket 16, which is located between the first connecting nut 14 and the connecting plate 12, so that the two sides of the gasket 16 abut the first connecting nut 14 and the connecting plate 12 respectively, so that the limiting plate 2 is more stably connected to the connecting plate 12.

[0041] In some embodiments, the first connecting nut 14 and the second connecting nut 15 are butterfly nuts, so as to facilitate rotation and thereby facilitate adjustment of the height of the limiting plate 2.

[0042] In some embodiments, the limiting seat 1 further comprises a rubber plate 17, which is fixedly connected to the lower side of the limiting plate 2, so that the metal workpiece can be more closely in contact with the polishing belt, so as to improve the polishing effect of the surface of the metal workpiece, and the rubber plate 17 abuts the metal workpiece instead of the limiting plate 2, so as to avoid wear of the metal workpiece as much as possible.
