The invention provides a multi-head cylindrical stone
copying machine. Front upright columns and back upright columns are correspondingly and vertically fixed on a base; The front upright columns and the back upright columns respectively comprise two upright columns symmetrically arranged on two sides of the base; a workpiece clamping mechanism is arranged on the front upright columns; the workpiece clamping mechanism can simultaneously clamp a plurality of machined workpieces and drive all the workpieces to synchronously rotate; and a workpiece
cutting device is arranged on the back upright columns. The workpiece
cutting device comprises a beam, a plurality of
cutting cutter heads and a
copying control device, wherein the beam which can move up and down as well as back and forth through a vertical-lifting and horizontal-shift drive mechanism is horizontally arranged between an back-left upright column and a back-right upright column; the cutting cutter heads are driven by a main shaft which is vertically supported on the beam along the longitudinal direction to synchronously
cut the workpieces; and the
copying control device tracks a copying template curved surface through photoelectric induction so as to control cutting drive mechanisms. The copying
machine has the advantages that the copying
machine can simultaneously machine a plurality of workpieces at a time, is simple to operate, reduces labor intensity, has high work efficiency and reduces production cost, and machined products are good in shape identity.
