Grinding and polishing mechanism of a stone mill

Abstract

A grinding and polishing mechanism of a stone grinding machine comprises a grinding and polishing frame, a sliding base unit, a first lifting unit and a grinding and polishing executing device. The grinding and polishing executing device comprises a grinding head unit, a spline shaft, a spindle box unit used for installing the spline shaft, a second lifting unit used for driving the spline shaft to vertically move along the spindle box unit, and a drive unit used for driving the spline shaft to rotate. The spindle box unit and the second lifting unit are both fixedly arranged on the sliding base unit. The first lifting unit is arranged for conducting ascending and descending on the whole sliding base unit; due to the fact that a stable lead screw lifting structure can be adopted in the first lifting unit, about 300 mm of stroke can be additionally increased for the grinding head unit, the grinding head unit of the whole stone grinding machine can have the stroke of 420 mm through addition of the original stroke of an air cylinder, and the grinding and polishing mechanism can be completely suitable for conducting rapid grinding and polishing on stone with the thickness being 400 mm or above.

Description

technical field [0001] The invention relates to a grinding and polishing component of a stone mill, in particular to a grinding and polishing mechanism of a stone mill. Background technique [0002] In the process of stone processing, in order to obtain the flatness and gloss of the surface, and at the same time fully reveal the inner color, pattern and luster of the stone, it is necessary to polish the stone. With the development of stone processing technology, great progress has been made in stone thickness setting and polishing technology, especially in the field of engineering slabs, stone polishing technology has developed from pure manual operation to fully automatic continuous polishing, making the polishing quality better. reliable. [0003] A Chinese utility model patent (application number: 201320140829.2) discloses a stone mill structure, which includes a spindle box and a cylinder connecting plate. Although this kind of stone mill can adjust the height of the g...
