Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser processing machines, in particular to special processing equipment for rod-shaped diamond tools. Background Art
[0002] Laser processing equipment is a combination of laser processing technology and CNC machine tools. It uses laser to replace cutting tools to process workpieces. In order to improve the degree of freedom of processing, laser processing equipment has been launched on the market, such as the publication number "CN109079342A" and the name "Five-axis linkage CNC laser cutting machine and process for the hole edge of the helmet blister shell". It includes X, Y, and Z axis moving mechanisms and A and B drive devices that can drive the laser head to move around the A and B axes. The laser head is set on the A and B drive devices, and then installed as a whole on the Z-axis moving mechanism. The Z-axis moving mechanism drives the laser head and the A and B drive devices to move together. Although it can meet the processing requirements, the weight of the laser head and the A and B drive devices is borne by the Z-axis moving mechanism, resulting in excessive load on the Z-axis moving mechanism, and relatively poor lifting and lowering speed and working stability.
[0003] In order to solve the above problems, the applicant has applied for a utility model patent application named "Five-axis laser processing equipment" with patent number "202221694952.4", which discloses a five-axis laser processing equipment, which includes a machine base, a marble base plate, a gantry, an X-axis moving mechanism, a Y-axis moving mechanism, a Z-axis moving mechanism, a five-axis turntable and a laser head module. The five-axis turntable is arranged on the marble base plate through the Y-axis moving mechanism, the X-axis moving mechanism is arranged on the gantry, and the laser head module is arranged on the X-axis moving mechanism through the Z-axis moving mechanism, that is, only the laser head module is arranged on the Z-axis moving mechanism, which effectively reduces the load of the Z-axis moving mechanism. Although it improves the working stability and working efficiency to a certain extent, during the processing, the laser head module still has a certain amount of shaking under the influence of the X-axis moving mechanism, and the structural stability of the gantry is not very high, so it is difficult to ensure the stability of the laser head module when it is working, which in turn affects the processing quality.
