Grinding head self-floating stone grinding and polishing machine

Abstract

A disclosed grinding head self-floating stone grinding and polishing machine comprises a rack, grinding and polishing grinding heads are arranged at the two sides of the rack in a staggered mode, the grinding and polishing grinding heads are connected with the rack through a lifting lead screw nut mechanism, each grinding and polishing grinding head comprises a self-floating grinding head unit, each self-floating grinding head unit comprises a center shaft, a spline shaft and a spline sleeve are sequentially arranged in the outer side of the center shaft in a sleeving mode, a cutter head seat is arranged at the bottom of the spline sleeve, grinding cutters distributed in the circumferential direction are arranged at the bottom of the cutter head seat at intervals, the spline sleeve is connected with the cutter head seat through a screw, the side face of the spline sleeve is hinged to the spherical surface of the cutter head seat, a slotted nut sleeves the end portion of the top end of a screw, a spring is arranged between the slotted nut and the spline sleeve, a knuckle bearing is arranged between the screw rod and the spline sleeve, a disc spring is arranged on the outer side of the center shaft in a sleeved mode, a disc spring upper seat is arranged between the disc spring and the center shaft, the top of the disc spring upper seat is tightly pressed on the step end face of the center shaft, and a disc spring lower seat is arranged between the disc spring and the spline sleeve.

Description

technical field [0001] The invention belongs to the technical field of grinding mechanical equipment for building material products, and relates to a self-floating stone grinding and polishing machine with a grinding head. Background technique [0002] Stone grinder is a mechanical equipment widely used in secondary finishing of PC imitation stone or stone products. In addition to the special equipment for special surface treatment requirements, for ultra-wide categories, planar or nearly planar boards (blocks) meet the finishing of decorative functional surfaces. This type of equipment is similar in structure to gantry milling and planing machines. It is conveyed longitudinally on the horizontal reference plane, and the grinding head on the equipment exerts positive pressure on the product surface along the vertical direction for grinding and polishing. There are generally two ways in the horizontal direction according to the structure of the equipment: ①The grinding head i...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a grinding head self-floating stone grinding and polishing machine. When encountering transitional edges, continuous feeding eliminates the grinding marks of connecting knives, and intermittent feeding of a single piece of grinding and polishing will reduce production efficiency; the second is to realize the grinding trajectory of the fixed tool post grinding disc Due to the overlap of the outer diameter of the cutter head in the given direction, the seamless connection between the cutter heads on the surface of the product is completed, which meets the decorative technical requirements of the overall grinding plane
