A bridge-type stone cutter with grinding and polishing functions

Abstract

A bridge type stone cutter with a polishing function comprises a crossbeam, two longitudinal beams, a moving seat, a lifting frame, a worktable and a cutting device. The cutting device is arranged on the lifting frame, a longitudinal moving mechanism is arranged among the crossbeam and the longitudinal beams, a transverse moving mechanism is arranged between the moving seat and the crossbeam, and a lifting moving mechanism is arranged between the lifting frame and the moving seat. The bridge type stone cutter is characterized by further comprising a polishing device, the polishing device is arranged on the lifting frame and comprises a spindle box, a spindle, a main motor, an abrasive disc and a vertical moving mechanism, the spindle box is arranged on the lifting frame in such a manner that the spindle box can vertically move up and down on the lifting frame, the spindle is vertically arranged on the spindle box, the main motor is arranged on the spindle box and is connected with the spindle to drive the spindle to rotate, the abrasive disc is arranged at the lower end of the spindle, and the vertical moving mechanism is connected with the spindle box to drive the spindle box to vertically move. The bridge type stone cutter has the advantages that a cutting function is integrated with the polishing function, a procedure for shifting stone between cutting equipment and polishing equipment and a procedure for clamping the stone are omitted, the stone processing efficiency is improved, and the labor cost is saved.

Description

technical field [0001] The invention relates to the field of stone processing machinery, in particular to a bridge-type stone cutter. Background technique [0002] Known, the bridge-type stone cutter mainly includes a crossbeam, two longitudinal beams, a movable seat (middle drag body), a lifting frame, a workbench and a cutting device arranged on the lifting frame; the crossbeam is erected between the two longitudinal beams, A longitudinal movement mechanism is installed between the beam and the longitudinal beam, and the moving seat is arranged on the cross beam so that it can move horizontally. A transverse moving mechanism is installed between the moving seat and the cross beam. There is a lifting and moving mechanism between the moving seat and the cutting device includes a knife rest set at the lower end of the lifting frame, a main shaft horizontally set on the knife rest along the longitudinal direction, a circular saw blade set on the main shaft, and a drive shaft c...

Problems solved by technology

[0002] Known, the bridge-type stone cutter mainly includes a crossbeam, two longitudinal beams, a movable seat (middle towing body), a lifting frame, a workbench and a cutting device arranged on the lifting frame; the crossbeam is erected between the two longitudinal beams, A longitudinal movement mechanism is installed between the beam and the longitudinal beam, and the moving seat is set on the cross beam so that it can move horizontally. A transverse moving mechanism is installed between the moving seat and the beam. There is a lifting and moving mechanism between the moving seat and the cutting device. The cutting device includes a knife rest arranged at the lower end of the lifting frame, a main shaft horizontally arranged on the knife rest along the longitudinal direction, a circular saw blade arranged on the main shaft, and a drive shaft connected by a belt and a pulley. Rotating main motor, the existing bridge-type stone cutter only has the function of cutting stone, and does not have the function of grinding and polishing stone. In stone processing, cutting and polishing are often two processes next to each other. Therefore, the design A bridge-type stone cutter integrating cutting, grinding and polishing has become urgent
