Device for adjusting height of galvanometer

Abstract

The invention belongs to the technical field of laser processing, and particularly discloses a device for adjusting the height of galvanometers. The device comprises a Z-axis bottom plate, galvanometer bottom plates and the galvanometers mounted on the galvanometer bottom plates. Galvanometer pin holes are formed in the positions, located on the side faces of the galvanometers, of the back faces of the galvanometer bottom plates. Adjusting through holes are formed in the positions, corresponding to the galvanometer pin holes, of the Z-axis bottom plate. One end of a pin shaft is arranged in each galvanometer pin hole in a transition fit manner. The middles of the pin shafts are arranged in the adjusting through holes in a clearance fit manner. Adjusting blocks are arranged at the other ends of the pin shafts in a transition fit manner. The upper ends of the adjusting blocks extend to the upper portion of the Z-axis bottom plate. Differential adjusting screws are mounted at the upper ends of the adjusting blocks. Multiple processing through holes are formed in the galvanometer bottom plates. Threaded holes corresponding to the processing through holes are formed in the Z-axis bottomplate. Half-thread bolts are arranged in the processing through holes. One ends of the half-thread bolts are arranged in the threaded holes in a threaded fit manner. The height of the galvanometers is adjusted, and meanwhile angle adjustment of other planes of the galvanometers is not influenced.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a device for adjusting the height of a vibrating mirror. Background technique [0002] The galvanometer is an optical component used in laser processing equipment. The laser beam is injected into the galvanometer, adjusted by the servo motor in the galvanometer, and then directed to the workpiece for processing. At present, most of the laser processing equipment using galvanometers on the market are single-station, which uses a single galvanometer for processing. In this case, the height adjustment of the galvanometer can be completed by moving up and down the Z-axis. For multi-station laser equipment, the number of galvanometers is equal to the number of stations, and these galvanometers are all fixed on the same Z-axis, but the galvanometers cannot be unified due to the error of the hole position and the gap between the threads during the fixing process. height, so a ...

Problems solved by technology

For multi-station laser equipment, the number of galvanometers is equal to the number of stations, and these galvanometers are all fixed on the same Z-axis, but the galvanometers cannot be unified due to the error of the hole position and the gap between the threads during the fixing process. height, so a height adjustment is required for a single galvanometer

The existing height adjustment technology basically uses sliders and rails, and then adjusts with self-made fine-pitch threads. Such a structure is expensive and the precision of self-made fine-pitch threads is not enough.
