Gantry type stone cutter

Abstract

The invention relates to a gantry type stone cutter. The gantry type stone cutter comprises a base, a trolley, two parallel support seats, a gantry frame, a lifting stand column, a combined sawing machine and a cutting motor, wherein a locking device sleeves the lifting stand column; the locking device comprises a locking base, an external-contacting brake and an internal-contacting brake; the external-contacting brake is assembled in the locking base; the internal-contacting brake is assembled between the inner side wall of the external-contacting brake and the outer side wall of the lifting stand column; the internal-contacting brake comprises a left internal-contacting brake and a right internal-contacting brake; the left internal-contacting brake and the right internal-contacting brake are combined to surround the outer side wall of the lifting stand column; an eccentric sleeve is arranged between the left internal-contacting brake and the right internal-contacting brake; the left internal-contacting brake and the right internal-contacting brake are articulated with the eccentric sleeve through a connection rod respectively; the eccentric sleeve rotates to enable the left and right internal-contacting brakes to be matched with the external-contacting brake so as to tightly hold and loosen the lifting stand column, so that the stability of the lifting stand column is improved; the swing of the lifting stand column in the high-load and high-vibration environment can be avoided, so that the cutting accuracy of the combined sawing machine is improved, and the service life of the combined sawing machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting machines, and more specifically refers to a gantry-type stone cutting machine. Background technique [0002] The gantry stone cutting machine is a commonly used stone processing machinery and equipment. It is mainly used for cutting various large or giant plates and plates. The existing gantry stone cutting machine includes a trolley for placing stones, and two parallel horizontal supports. A frame, a gantry that can move on the horizontal support frame, and a lifting column on the gantry are provided. A cutting combination saw is carried below the lifting column, and a cutting motor for driving the rotation of the cutting combination saw is fixed above the lifting column. However, the lifting column of the cutting machine is slidingly matched with the column sleeve on the gantry frame. In a high-load and high-vibration working environment, wear and tear will inevitably occur between the lifting c...
