Description

Technical Field

[0001] The utility model relates to the technical field of instrument and meter production, and more particularly to a polishing device for instrument and meter manufacturing. Background Art

[0002] In the manufacturing process of instruments and meters, the grinding process is an important processing step. During the casting or machining process, burrs may appear on the edges and corners of parts. Grinding can remove these burrs to ensure the smoothness of the parts and the accuracy of assembly. Through grinding, the size of the parts can be fine-tuned to achieve the accuracy required by the design drawings. Grinding can remove scratches, scars and other defects on the surface of the parts, improve the beauty and functionality of the parts, and significantly improve the surface finish of the parts. This is especially important for instruments that require precise measurement.

[0003] At present, for large disc-type instrument parts, grinding discs cannot be used to grind the sides. Manual grinding is generally used, which is time-consuming, labor-intensive and inefficient. When using machines for grinding, the grinding roller will produce a certain amount of wear. However, the installation and replacement process of the existing grinding roller and motor is complicated and inconvenient, resulting in reduced equipment maintenance efficiency and extended equipment downtime, thereby affecting the execution of production plans and the achievement of production goals.
