Three-dimensional carving machine

Abstract

The invention provides a three-dimensional carving machine, and belongs to the technical field of machines. By adoption of the three-dimensional carving machine, the carving precision can be improved.The three-dimensional carving machine comprises a plurality of carving assemblies, a strip-shaped tool rest connected with the carving assemblies, and a clamping assembly used for clamping workpieces. Each carving assembly comprises a base arranged on the tool rest and a driving motor fixed to the base and used for driving a tool to rotate. The bases are fixed in the axial direction of the driving motors relative to the tool rest and can move in the radial direction of the driving motors relative to the tool rest. Positioners used for adjusting the movement of the bases relative to the tool rest are arranged on the side edges of the bases and can position the bases in the radial direction of the driving motors. According to the three-dimensional carving machine, the positions of tools canbe slightly adjusted, so that positional deviations, caused by manufacturing and assembling errors, of the tools are avoided, it is guaranteed that the tools can be located at machining positions required by the design, and accordingly, the carving precision of the carving machine is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a three-dimensional engraving machine. Background technique [0002] From the processing principle, the engraving machine is a kind of drilling and milling combined processing machine. Among them, the three-dimensional engraving machine is an industry classification of engraving machines. It is a new type of CNC equipment in recent years. Its working principle is very similar to that of CNC milling machines. Achieve the effect of automatic engraving. The three-dimensional engraving machine has a wide range of applications, and can be applied to processing and engraving of wood, stone, metal, plastic, etc. Its automatic engraving effect is good, and the engraving is fast, so it is often used in mass and rapid production of workpieces. [0003] For example, the Chinese patent document [application number: 201810575701.6] discloses a multi-functional engraving machine, including a ...

Problems solved by technology

[0008] This three-dimensional engraving machine improves the engraving components so that the position of the tool can be fine-tuned, thereby overcoming the defect that the engraving accuracy cannot be improved due to the existence of manufacturing and assembly errors in the prior art; the specific principle is as follows: In the engraving components, The motor shaft of the driving motor is fixedly connected with the tool to drive the tool to rotate, that is to say, the adjustment of the position of the tool can be realized by adjusting the position of the driving motor. Therefore, by setting a seat for fixing the driving motor, the seat is arranged On the tool holder, this allows the seat to be axially fixed on the tool holder and can move relative to the tool holder in the radial direction of the drive motor, and then a locator is set on the side of the pedestal to adjust the position of the seat relative to the tool holder. The moving distance of the tool holder allows the seat to be positioned in the radial direction of the drive motor, so that the radial position of the drive motor relative to the tool holder can be adjusted and positioned, that is, the radial position of the tool relative to the tool holder can be adjusted and positioned; Through the above design, when the workpiece is accurately clamped on the clamping assembly, fine-tuning is performed on the radial position of the tool so that the centerline of the tool and the centerline of the clamping assembly are on the same plane, thereby ensuring that the tool is in the same plane. The processing position where the design requires will not produce deviations, thus avoiding the problem that the engraving accuracy cannot be guaranteed due to manufacturing errors, thereby improving the engraving accuracy of the engraving machine
