A multi-grain disc grinding device

Abstract

The invention discloses a multi-granularity grinding-disc grinding device. The multi-granularity grinding-disc grinding device comprises a main rack, a main grinding disc arranged on the main rack, a power motor used for driving the main grinding disc to rotate, and a gravity press block used for pressing a workpiece onto the main grinding disc, wherein a workpiece location groove is formed in a bottom of the gravity press block; the main grinding disc comprises a base disc and a plurality of annular grinding material layers which are coaxially arranged in sequence from inside to outside, the base disc is in rotation fit with the main rack, and a rotation axis of the base disc is superposed with an axis of the base disc; and the annular grinding material layers are all arranged on a top surface of the base disc, and in each two adjacent annular grinding material layers, a grinding material granularity of the annular grinding material layer with a small inner diameter is less than a grinding material granularity of the annular grinding material layer with a large inner diameter. The multi-granularity grinding-disc grinding device disclosed by the invention has the beneficial effects that the structure is reasonable, continuous grinding can be effectively implemented on the workpiece, and grinding machining from a large granularity to a small granularity can be completed through one grinding, without the need of a plurality of grinding machines, so that a machining process is convenient and efficient; and automatic cleaning capacity for grinding waste is high, a negative effect on a machining process of grinding equipment is small, and an excellent grinding effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of grinding processing, in particular to a multi-grain disc grinding device. Background technique [0002] Grinding devices such as flat grinders have been widely used at present. The grinding device can grind one or more surfaces of the workpiece (such as a plate) so that the surface precision (surface roughness) of the workpiece can reach the required level. In the actual grinding process, the grinding of the surface of the workpiece is often not completed at one time, especially for workpieces with high surface accuracy requirements, it needs to be ground "from coarse to fine" by multiple grinding machines (each The abrasive particle size of the mill that passes once is smaller than the abrasive particle size of the mill that passed the previous time. This is similar to the basic principle of multiple milling and multiple borings. The purpose is to avoid single-shot grinding of the workpiece. The damage...

Problems solved by technology

In the actual grinding process, the grinding of the surface of the workpiece is often not completed at one time, especially for workpieces with high surface accuracy requirements, it needs to be ground "from coarse to fine" by multiple grinding machines (each The abrasive particle size of the mill that passes once is smaller than the abrasive particle size of the mill that passed the previous time. This is similar to the basic principle of multiple milling and multiple borings. The purpose is to avoid single-shot grinding of the workpiece. The damage to the workpiece caused by the excessive processing amount is also to ensure a better processing effect) before the grinding process can be completed. This requires the workpiece to be transposed on multiple grinding machines, which is time-consuming and labor-intensive, and the labor intensity of the workers is relatively high. Large, and the grinding efficiency is low
