Description

Double-beam numerical control planer type boring and milling machine Technical Field The invention relates to the technical field of milling machines, in particular to a double-beam numerical control planer type boring and milling machine. Background In the field of machining, a numerical control planer type boring and milling machine is used as important machining equipment, and the performance of the numerical control planer type boring and milling machine directly influences the machining quality and the production efficiency of products. The traditional numerical control planer boring and milling machine exposes a plurality of problems in practical application, and improvement is needed. In the processing process, the problem of collision between the cutter and the placing plate is more remarkable. For example, when the plate is perforated, hollowed out and the like, the cutter is very easy to contact with the placing plate. In the intermittent cutting process of milling, cutting force and cutting vibration are large, and particularly in the rough machining of large parts, the risk of collision between a cutter and a placing plate is high because of the structural design limitation of the traditional planer type structure milling machine like the one mentioned in patent CN 200920053846. The cutter is worn and damaged, the service life of the cutter is shortened, the production cost is increased, machining accidents can be possibly caused, and the smooth progress of machining and the product quality are affected. The clamping and positioning modes of the plates are also insufficient. The traditional press-clamping mechanism is difficult to accurately adapt to the characteristics of different plates, and when a special-shaped piece is processed, the condition of uneven clamping force distribution often occurs. When a machine tool such as the machine tool in patent CN201010101919 is used for processing a large composite material component in the aerospace field, and facing such complex workpieces, the traditional clamping mode cannot effectively avoid the problems of sheet flutter, material surface damage and the like, the processing precision is seriously affected, and the high-precision processing requirement is difficult to meet. The low degree of automation in the loading and unloading processes is also a great difficulty. Most traditional devices rely on manual operation, and are labor intensive and inefficient. For example, when some milling machines are used for feeding and discharging plates, workers are required to manually carry and adjust positions, so that labor and time are consumed, positioning inaccuracy is easily caused by artificial factors, machining precision is affected, and workers can be accidentally injured in the frequent carrying process. In addition, chips generated during processing are liable to cause damage to the equipment transmission components. As mentioned in patent CN201220618897, if the scraps generated during processing enter the transmission parts such as the threaded rods of the first linear module and the second linear module, the parts will be blocked, the transmission stability of the modules will be affected, so that the operation of the equipment will be failed, the production efficiency will be reduced, and the maintenance cost of the equipment will be increased.
