Large frame type gantry cutting machine

Abstract

The invention provides a large frame type gantry cutting machine, comprising two gantry type brackets, two longitudinal rails, a main base body, walking devices, a hoisting frame, a driving device, a main shaft, a saw bit and a main motor, wherein the two gantry type brackets are transversely arrayed at intervals; the two longitudinal rails are arranged on cross beams of the two gantry type brackets and horizontally extend in a longitudinal direction; the main base body is arranged between the two longitudinal rails through a movable frame; the walking devices are arranged at two sides of the main base body and are matched with the two longitudinal rails; the hoisting frame is movably arranged on the main base body in a vertically hoisting manner; the driving device is arranged between the main base body and the hoisting frame and is used for driving the hoisting frame to hoist and move; the main shaft is horizontally arranged at the lower end of the hoisting frame in the longitudinal direction; the saw bit is arranged on the main shaft; and the main motor is arranged at the upper end of the hoisting frame and is connected through a transmission mechanism to drive the main shaft to rotate. The large frame type gantry cutting machine, provided by the invention, has the advantages of simple structure, accuracy in action, stability and the like.

Description

technical field [0001] The invention relates to the field of stone processing, in particular to a stone cutting machine. Background technique [0002] Most of the existing stone cutters are bridge-type stone cutters. The bridge-type stone cutter is mainly composed of beams, longitudinal beams and host devices. The longitudinal beams are provided with longitudinal rails that extend vertically and horizontally. On the longitudinal track of the longitudinal beam, the host device includes a middle tow body that is movably arranged on the cross beam along the cross beam, a lifting frame that is arranged on the middle tow body, a driving device that drives the lifting frame to move up and down, and a knife that is arranged at the lower end of the lifting frame. Seat and upper end motor seat, and the horizontal traveling device that drives the dragging body to move along the crossbeam. The two ends of the crossbeam are provided with longitudinal traveling devices that cooperate wit...

AI Technical Summary

Problems solved by technology

Since the host device is movable on the beam, the rigidity is low, and large vibration will be generated during the stone cutting process, which will affect the cutting accuracy and stability of the stone cutter
