Background technology:
[0002] In industrial production, foreign matter on the surface of thin sheet materials needs to be polished and removed. For example, in the production process of thermal print heads, the surface of the ceramic insulating substrate of its main component will reduce its flatness due to the presence of foreign matter after multiple printing and sintering processes. This situation will seriously affect the printing effect. In order to improve the printing effect of the entire thermal print head, it is necessary to grind the foreign matter on its surface. Usually, a grinding device is used to grind the surface of the ceramic substrate. The existing device for grinding foreign matter on the surface of thermal print heads has the following disadvantages: the unwinding roll has no damping device, and the sanding belt is easily squeezed and broken during the grinding process; the pneumatic slide is used to drive the grinding head to reciprocate for grinding, the speed of the slide is unstable, the impact force is large, and the grinding stroke requires manual adjustment of the sensor position; it is inconvenient to replace the fixture corresponding to different models of products. Due to the wide variety of products to be processed, different fixtures need to be replaced, which greatly increases the adjustment and installation time and reduces production efficiency.

Specifically, more than two locking screw holes are provided on the working platform. When in use, the adjustment block is used to abut against the end of the material to be processed, and the adjustment block is locked with the corresponding locking screw hole on the working platform by a locking screw to complete the limitation of the material to be processed.
[0009] The working platform described in the utility model is also provided with an adjustable clamping assembly on the side, and the adjustable clamping assembly is provided with a clamping push cylinder for pushing the material to be processed against the positioning boss of the working platform.
