Three-dimensional engraving machine

Abstract

The invention provides a three-dimensional engraving machine, and belongs to the technical field of an engraving machine. The three-dimensional engraving machine solves the problem of poor stability of a three-dimensional engraving machine in the engraving process in the prior art. The three-dimensional engraving machine comprises a machine frame and a movable engraving platform arranged on the machine frame, wherein a straight strip-shaped cutter frame used for fixing a cutter is arranged above the engraving platform, the machine frame comprises two upright posts, the two upright posts are respectively and vertically arranged at the two sides of the engraving platform, guide rails in vertical arrangement are respectively arranged on each upright post, a support plate capable of vertically moving along the guide rail is arranged on each corresponding guide rail, the two ends of the cutter frame are respectively connected onto the corresponding support plates, and ascending and descending motors driving the support plates to synchronously and vertically move are also arranged on the machine frame. The three-dimensional engraving machine has the advantages that the operation is stable, and the processing precision is high.

Description

technical field [0001] The invention belongs to the technical field of engraving machines, and relates to a three-dimensional engraving machine. Background technique [0002] From the processing principle, engraving is a combination of drilling and milling. It has a wide range of applications, including woodworking engraving machines, laser engraving machines, advertising engraving machines, jade engraving machines, stone engraving machines, cylindrical engraving machines, etc. Three-dimensional engraving machine is an industry classification of engraving machine. It is a new type of CNC equipment in recent years. Its working principle is very similar to that of CNC milling machine. The engraving effect, the three-dimensional engraving machine has a wide range of applications, and even replaces the manual engraving technology, laying the foundation for mass and rapid production of products. [0003] Such as China's invention patent application (application number: 200810060...

AI Technical Summary

Problems solved by technology

This three-dimensional engraving machine has the following deficiencies: ①. A single motor is used to act on the middle part of the tool holder to move the tool holder up and down. The design makes the two ends of the tool holder hang in the air without support points, resulting in poor stability of the tool holder. When the tool is processing the product, the tool is likely to vibrate with the tool holder, which affects the engraving accuracy of the three-dimensional engraving machine;② 3. The tool rack of the three-dimensional engraving machine not only needs to move up and down, but also moves horizontally left and right. Therefore, a drive motor, a screw rod, and a horizontal guide rail are provided to enable the tool to move horizontally. The three-dimensional engraving machine has a high center of gravity, which will cause the frame to tilt and shake during the movement of the tool frame, which greatly affects the stability and quality of tool processing.

③. Beams, pallets and other components are located on one side of the middle of the tool holder, so that the working space of the three-dimensional engraving machine is small, and it can only engrave small-sized products, and the versatility is insufficient; ④. The engraving angle of the tool in the three-dimensional engraving machine cannot Therefore, the three-dimensional engraving machine can only carve products with a relatively simple shape and structure, and the practicability is not strong
