Large-format laser high-speed machining mechanism

Abstract

The invention belongs to laser machining technology, and particularly relates to a large-format laser high-speed machining mechanism. The large-format laser high-speed machining mechanism comprises aframe body. The frame body is provided with a drive stepping motor, a bias slider-crank mechanism, a linear differential motion travel multiplying mechanism and a laser processing head. The bias slider-crank mechanism comprises a crank and a connecting rod, wherein the crank is connected with the drive stepping motor, and the connecting rod is hinged to the crank. The linear differential motion travel magnifying mechanism comprises a fixedly-arranged fixed rack, a sliding rack and a rolling wheel which is engaged with the fixed rack and the sliding rack, the rolling wheel is connected with theend portion of the connecting rod, the fixed rack and the sliding rack are arranged in parallel, the rolling wheel is arranged between the fixed rack and the sliding rack, the rolling wheel does reciprocating rectilinear motion relative to the fixed rack, and the sliding rack is fixedly connected with the laser machining head. By means of the large-format laser high-speed machining mechanism, high-speed and high-precision batch welding, cutting and nicking of large-format workpieces can be achieved, and the laser machining efficiency can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a large-format laser high-speed processing mechanism. Background technique [0002] Compared with traditional processing technology, laser processing technology has the advantages of less material waste, obvious cost effect in large-scale production, and strong adaptability to processing objects. It has been widely used in the microelectronics industry, automobile industry, and shipbuilding industry, especially because the laser processing process is non-contact and the laser beam movement can achieve high-precision control, making it very suitable for processing speed or Occasions where high efficiency is required and cannot be achieved by conventional processing. [0003] To achieve high-speed laser processing, its motion control structure is particularly important. At present, the common laser processing motion control methods are mainly divided into two ...

Problems solved by technology

However, when performing large-format processing, the mechanical transmission type is limited by the large transmission structure, and there is always a bottleneck in the improvement of processing efficiency, and the mechanical structure will also have a great impact on its processing accuracy when it moves at high speed. Therefore, although the mechanical transmission Although the method can be well qualified for some large-scale and complex laser processing, it cannot be well satisfied for some batch processing occasions where the processing method is relatively simple but the processing output requirements are high.
