Four-axis universal engraving machine for double work surfaces capable of circularly engraving and flatly engraving

Abstract

The invention provides a four-axis universal engraving machine for double work surfaces capable of circularly engraving and flatly engraving, wherein two work surfaces are arranged on a base, two sides of each work surface are respectively provided with a Y-directional guide rail, and two bottom ends of a portal frame are slidably arranged on the Y-directional guide rails; one ends of the work surfaces are fixedly provided with a main spindle box respectively, and a plurality of driving turntables are arranged on the main spindle boxes; tailstock boxes are arranged on the work surfaces, a plurality of lead screw thimbles which are coaxial with the driving turntables are arranged on the tailstock boxes, the work surfaces are corrugated surfaces, two sides of each corrugated surface and the middle corrugated top are respectively provided with a slide rail, and the bottom ends of the tailstock boxes are slidably arranged on the slide rails by slide blocks. Plane-engraving work surfaces are arranged on the corrugated work surfaces. The four-axis universal engraving machine has the advantages that the fragments are more convenient and quicker to remove due to the corrugated work surfaces; the thimbles at the center of the driving turntables have an elastic stretching capability, so that a workpiece is faster to clamp; and the double work surfaces are convenient to convert, so that the four-axis universal engraving machine has dual functions of circularly engraving and flatly engraving, therefore, not only can the production space be saved, but also the production cost can be reduced.

Description

technical field [0001] The invention relates to an engraving machine, in particular to a four-axis general-purpose engraving machine with double working surfaces capable of engraving round and flat surfaces, and can be used for engraving round and flat workpieces. Background technique [0002] Existing engraving machines can only engrave circular workpieces or planes, and have a single function; some models set the workbench inside the frame close to the ground. Due to the narrow space, it is particularly difficult to clamp the workpiece. Cleaning The debris is also inconvenient, which greatly increases the processing time of the workpiece and the labor intensity of the operator. Since the clamping device is set on the running track, it will inevitably make it impossible to process workpieces with larger diameters. Even if it is barely capable, due to the heightened axis The machining accuracy is greatly reduced, and finally the machining accuracy of the workpiece cannot be ...
