Abstract

The invention discloses a small multi-axis linkage ultrasonic vibration---an electromagnetic auxiliary increasing and decreasing material processing device. The device comprises a steering movable workbench, an ultrasonic vibration---electromagnetic auxiliary device, a mill---milling composite processing device and a laser cladding device, wherein a machine tool base is arranged below the mill---milling composite processing device, the ultrasonic vibration---electromagnetic auxiliary device is fixedly installed on the steering movable workbench, the steering movable workbench is installed on the machine tool base, and the laser cladding device is fixedly arranged on the right side of the upper surface of the machine tool base. According the device, through the steering movable workbench, the process switching of the mill---milling composite processing and the laser cladding processing can be achieved under the condition that workpieces need not to be loaded and unloaded, the processingerror is reduced, and the processing efficiency and the processing precision are improved; in addition, the ultrasonic vibration---electromagnetic auxiliary device can generate a composite field in the laser cladding stage to achieve the convection of molten metal in the cladding process, the metal composition is refined, and the pores and cracks in the cladding layer are reduced, thus improvingthe performance of workpiece products; finally, the device has the advantages of being simple in structure, low in control difficulty and easy to operation.

Description

technical field [0001] The invention belongs to the field of composite processing of adding and subtracting materials, and in particular relates to a small multi-axis linkage ultrasonic vibration-electromagnetic auxiliary adding and subtracting materials processing device. Background technique [0002] In recent years, with the continuous improvement of the level of science and technology, laser cladding technology has ushered in a golden stage of vigorous development. Especially in aerospace, shipbuilding and biomedical fields, it has been widely used. Although laser cladding technology has changed the traditional mechanical processing mode and avoided the waste of materials caused by mechanical processing technologies such as turning, milling, and grinding, the products processed by this processing technology have different mechanical properties (surface quality and shape accuracy), etc. However, the product application requirements are still not met.

Problems solved by technology

For example, in the patent (CN205024324U), a steady magnetic field is used to assist laser cladding. Although this processing method has a certain influence on the growth of the metal structure during the solidification process to a certain extent, there will still be many pores in the cladding layer. This seriously affects the performance of the workpiece material itself
