Description

Material-increasing and material-reducing double-station synchronous machining method and device for axial-center-variable revolving body

Technical Field

The invention relates to the field of desktop type laser processing equipment, in particular to a material increase and decrease double-station synchronous processing method and device for an axis-variable revolving body.

Background

In traditional laser processing equipment, carry out increase material processing earlier, subtract material processing again, increase and decrease material processing can not accomplish simultaneously, need go up unloading operation and relocation again, though there is partial increase and decrease material equipment complex at present, but there is the interference problem between each station, leads to increase and decrease material equipment complex to have certain limitation.

With the rapid development of the manufacturing industry in China, the customization demand of novel mechanical equipment is increasing day by day, and the structural integration and structural complexity degree of various parts are continuously improved. Meanwhile, in the aspect of processing high-performance complex parts, various requirements such as customization, high precision, high efficiency, low cost, low energy consumption, integration and integration are correspondingly provided. This provides a broad platform for development and technological improvement for additive/subtractive composite manufacturing techniques.

In order to further improve the processing precision and the surface quality of the additive forming part, a grinding processing link is required to be arranged in the material reducing process of the additive/material reducing composite manufacturing equipment. Moreover, a large amount of abrasive dust is generated during grinding, and under the condition that the sealing performance of the transmission system is insufficient, key transmission components such as a ball screw and a guide rod of the equipment are easy to accumulate abrasive dust and are seriously worn (at the moment, the abrasive dust acts as abrasive particles), so that the subsequent working precision of the equipment and the service life of the transmission system of the equipment are seriously influenced.

The existing desktop type increasing/decreasing composite manufacturing equipment lacks the consideration of protecting the inert gas in the laser material increasing process. At present, a large proportion of high-performance complex parts are all made of metal materials, and the metal materials have relatively high requirements on oxidation resistance of a specific gas environment in the process of laser additive rapid forming. Therefore, when the workpiece raw material is made of a metal material, the metal material is easily oxidized due to the lack of the protection of inert gas in the laser material increasing process, so that the forming quality of the metal material is influenced, and the method is narrow in application range and not suitable for processing the metal material. In addition, when the material is ground and cut, the splashed metal material may cause a safety hazard to an operator. The additive processing equipment of the existing additive/subtractive composite manufacturing equipment is only used for forming and manufacturing a specific or appointed material, and the consideration of composite material parts is lacked. Particularly, the material reducing processing link is really developed comprehensively with diversity and diversification. Generally, the material reducing part is only used for cutting (mainly milling) one surface in the material forming process. For part of complex parts, the parts need to be further ground after material increasing/reducing processing, but the material reducing function is not complete, so that the flexibility of the material reducing processing is lower under special working conditions. Particularly, when the parts are irregular in shape and inconsistent in height, the material increasing and decreasing processing cannot be synchronously performed, the material increasing processing and the material decreasing processing need to be separately performed, the time and the process of repeated positioning are increased, and the production efficiency is low. In summary, the existing material increasing/decreasing composite manufacturing technology and equipment design still have many defects.
