Five-axis machining center and stone machining method thereof

Abstract

The invention discloses a five-axis machining center and a stone machining method thereof. The five-axis machining center is of a five-axis-linked structure which is composed of an axis X, axes Y, an axis Z, an axis C and an axis B. A framework body is of a gantry type structure. The axes Y are arranged in a bilateral symmetry mode and longitudinally arranged on a Y-axis base. The axis X is transversely arranged on a cross beam, and the cross beam is connected to a pair of Y-axis sliding tables in a crossing mode. The perpendicularly-arranged axis Z is connected with an X-axis sliding table through a Z-axis sliding table. The lower end face of a Z-axis body is connected with the axis C. An output disk of the axis C is connected with a U-shaped end in the axis B, and the U-shaped end is connected with a spindle motor through a connecting flange. A workbench assembly is arranged between two overhead walls. A tool magazine assembly is arranged on the inner side face of one overhead wall, and an electrical control cabinet is arranged on the outer side of the other overhead wall. According to the five-axis machining center and the stone machining method thereof, cutting of special-shaped plates and engraving of stereoscopic stone can be completed automatically through five-axis linkage, clamping is easier, positioning is accurate, the machining cost is low, the working efficiency is high, the surface smoothness of workpieces is high, the machining precision is improved, and the quality of all products is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of stone machinery, in particular to a five-axis machining center and a stone processing method thereof. Background technique [0002] At present, traditional three-axis machine tools only have X-axis, Y-axis, and Z-axis structures. They have a single function and can only perform simple cutting and rotary milling. For the processing of complex workpieces, it is necessary to cooperate with a variety of specific fixtures and go through multiple installations. Clamping and multiple processing processes can achieve the final product. However, multiple clamping brings inaccurate positioning, lower relative accuracy, lower work efficiency, troublesome operation, high requirements for operators, and long processing time. In addition, the processed plates need to be removed manually, which increases the labor intensity and is not safe and hygienic. [0003] Most of the existing three-dimensional carvings are main...

Problems solved by technology

[0002] At present, traditional three-axis machine tools only have X-axis, Y-axis, and Z-axis structures. They have a single function and can only perform simple cutting and rotary milling. For the processing of complex workpieces, it is necessary to cooperate with a variety of specific fixtures and go through multiple installations. Clamping and multiple processing processes to achieve the final product

However, multiple clamping brings inaccurate positioning, lower relative accuracy, lower work efficiency, troublesome operation, high requirements for operators, and long processing time.

In addition, the processed plates need to be removed manually, which increases labor intensity and is not safe and hygienic

[0003] Most of the existing three-dimensional carvings are mainly manual carvings, which are labor-intensive, require a huge amount of labor, and have low production efficiency. Artifacts

There are also a few XYZ three-axis machining methods, which can only process relatively simple patterns; four-axis, that is, XYZ and rotary axis machining methods, can only process fonts and patterns on cylindrical surfaces; the above three-axis and four-axis machining methods can only process Patterns on the sunny side cannot process complex graphics and negative side patterns, and the use range is narrow

[0004] In the process of curved surface processing in the existing special-shaped processing, only the relatively simple curved surface of the workpiece can be processed, and the negative surface and complex side of the workpiece cannot be processed. The processing efficiency is low and the positioning is relatively troublesome.
