Description

Production equipment and production process of thin-wall internal and external tooth structure Technical Field The invention belongs to the technical field of part machining, and particularly relates to production equipment and production technology of a thin-wall internal and external tooth structure. Background In the field of mechanical manufacturing, the thin-wall internal and external tooth structure is widely applied to products such as small-sized transmission mechanisms, precise instruments, automobile parts and the like, has the characteristics of compact structure, light weight and high transmission efficiency, and can meet the development requirements of equipment miniaturization and light weight. Along with the improvement of the industrial automation level and the rapid development of the precision manufacturing industry, the market has raised higher and higher requirements on the machining precision, the surface quality and the production efficiency of the thin-wall internal and external tooth structure, and has raised more stringent standards on the deformation control of workpieces in the machining process. At present, the common mode of tooth form processing among the prior art is cutting processing, specifically includes multiple forms such as milling teeth, gear hobbing, gear shaping, and this type of processing mode is through the cutter to the work piece cutting get rid of unnecessary material to the required tooth form structure of shaping, it is comparatively extensive to use in thick wall tooth spare, the better tooth form processing of rigidity, can realize the tooth form processing of certain precision. However, the conventional cutting method has a plurality of defects which are difficult to overcome for the thin-wall internal and external tooth structure, and is not suitable for tooth profile processing of thin-wall parts. Firstly, the thin-wall workpiece is thin and poor in rigidity, in the cutting process, the cutting force between the cutters and the workpiece can cause obvious elastic deformation and plastic deformation of the thin-wall workpiece, so that the problems of size deviation, tooth distortion and the like of the machined tooth profile cannot meet the precision requirement of precision machining, secondly, cutting stress is generated on the surface of the workpiece in the cutting process, the stress concentration easily causes the defects of cracking, deformation and the like of the thin-wall workpiece, the qualification rate of the workpiece is greatly reduced, the production cost is increased, a large amount of cuttings are generated in the cutting process, the cuttings are easily attached to the surface of the workpiece or the cutters, the surface quality is affected, the cutter abrasion is possibly increased, the machining efficiency and the service life of the cutter are reduced, in addition, the cutting process is a removal type machining, the material utilization rate is low, and for the thin-wall workpiece, the structural strength of the workpiece is further reduced due to excessive material removal, and the service performance is affected. Besides the inherent defects of the cutting processing, the existing part of non-cutting processing modes (such as stamping forming) have limitations in the processing of the inner teeth and the outer teeth of the thin wall, the problems that the tooth profile forming is irregular, the surface burrs are more, the complex tooth profile processing cannot be adapted, the impact force is larger in the stamping process, and the thin wall workpiece is easy to generate irreversible deformation and even damage are often caused. In conclusion, the existing tooth form processing technology mainly uses cutting processing, the mode cannot adapt to the processing requirements of the thin-wall internal and external tooth structures, and the problems of low processing precision, easy deformation of workpieces, low qualification rate, insufficient production efficiency and the like exist, so that the precision, high efficiency and batch processing requirements of the thin-wall internal and external tooth structures in industrial production are difficult to meet. Therefore, developing a production device and a production process capable of solving the defects in the prior art and adapting to the processing of the thin-wall inner and outer tooth structures becomes a technical problem to be solved by the current technicians in the field.
