Description

Technical Field

[0001] The present invention relates to the technical field of grinding processing, in particular to a grinding machine. Background Art

[0002] In modern industrial production, the finishing of sealing surfaces is a key link in ensuring the sealing performance of equipment, and is widely used in mechanical manufacturing, petrochemicals, aerospace and other fields. The sealing surface is usually composed of the contact between metal and non-metallic materials, and its processing quality directly affects the sealing effect and service life of the equipment. For example, after the sealing surface of a certain type of solenoid valve core assembly is rolled and finished, there is a metal flange at the metal and non-metal contact surface, which needs to be removed by grinding. The current processing solution is to draw an 8-shaped mark on the platform for grinding. The grinding time for a single piece is about 20 minutes. The processing relies entirely on manual labor, and the processing accuracy is difficult to guarantee. It is easy for human factors to cause unstable processing quality. Although semi-automatic equipment has improved efficiency to a certain extent, it still requires frequent manual intervention and cannot achieve fully automated production, which seriously affects production efficiency. In addition, multiple repeated operations are required to achieve the ideal processing effect, resulting in low overall production efficiency.

[0003] In the prior art, a fully automatic metallographic grinding machine disclosed in a Chinese patent with the announcement number CN 116652808 A includes a structural support frame, a grinding disc, a lifting platform, a driving mechanism, a grinding disc linear feed mechanism, and a quality confirmation module. The structural support frame includes a grinding disc drop barrel and a grinding disc loading barrel that matches the grinding disc. The lifting platform and the structural support frame are connected by four support rod components and the positioning nuts and springs thereon. The driving mechanism is connected to the structural support frame by screws, and the grinding disc linear feed mechanism is connected to the structural support frame by screws. Although this patent can realize the centralized storage of grinding discs and the automatic replacement of grinding discs, the utilization rate of sandpaper is high, the cost is saved, and remote control is achieved through software; the grinding results of each process can be observed through a camera, but the structure of this patent is complex and it only rotates in one direction, resulting in low grinding efficiency.
