Description

Technical Field

[0001] The invention relates to the technical field of valve manufacturing, in particular to a door core grinding device. Background Art

[0002] In the field of industrial production, door core grinding is a crucial processing step in the valve manufacturing process. Its surface quality directly determines the sealing performance, fluid control accuracy and overall service life of the valve. The door core and the valve seat must fit very closely, and their surface flatness and finish must meet precision standards to ensure that they can operate normally under high pressure, high temperature and corrosive media environments. However, traditional door core grinding methods mostly rely on manual operation or primary mechanical equipment, which is inefficient and has many limitations. Manual grinding is not only labor-intensive, but also prone to uneven force on the workpiece due to improper operation, thus affecting the surface processing quality.

[0003] Traditional grinding equipment usually adopts a fixed single structure design, which has many shortcomings in terms of workpiece positioning, grinding head adjustment and driving mode. For example, the positioning method of the workpiece is simple, usually relying on manual adjustment of the position or fixing with a clamping device, which can easily cause grinding deviation due to errors, thus affecting the surface processing quality. At the same time, due to the lack of stability guarantee during the operation of the equipment, the grinding head is prone to vibration or deviation, resulting in poor grinding uniformity. For workpieces of different sizes or shapes, traditional equipment cannot provide flexible adjustment functions, and frequent replacement of fixtures or manual adjustment are required, which greatly reduces production efficiency. In addition, the driving method of traditional equipment is mostly single-point drive, with low power transmission efficiency, which makes it difficult to meet the needs of complex grinding tasks.
