[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The surface grinding processing device for the manufacture of hardware products is provided with a grinding mechanism. When the grinding work is performed, the second unit is started, and the transmission rod is driven to rotate, so that the grinding roller rotates. During the processing of the workpiece, when the surface of the workpiece is irregular, the grinding roller will move backward when it touches the raised block. At this time, the first telescopic spring will be compressed, and the first telescopic rod will be driven to contract.

When the grinding roller moves forward, it will drive the limit plate to move forward, and at the same time the connecting rod rotates clockwise, so that the driven gear is always in contact with the rotating disc under the pressure of the second telescopic spring. On the contrary, when the grinding roller moves backward, the limit plate moves backward, and the second telescopic spring resets and extends, pushing the connecting rod to rotate counterclockwise, so that the driven gear is still in contact with the rotating disc, maintaining continuous power output, and the rotation direction of the rotating disc is always opposite to that of the grinding roller, thereby increasing the friction of the grinding process, improving the grinding efficiency, and reducing the energy consumption of the grinding process.
