Description

An anti-vibration device for a CNC milling machine

technical field

The invention relates to the technical field of numerical control milling machines, in particular to an anti-vibration device for numerical control milling machines.

Background technique

CNC milling machine is a kind of CNC machine tool with strong processing functions. The rapidly developed machining centers and flexible processing units are all produced on the basis of CNC milling machines and CNC boring machines. Both of them are inseparable from the milling method. The process is the most complicated, and the technical problems that need to be solved are the most. Therefore, when people research and develop the software of the numerical control system and automatic programming language, they have always regarded milling as the key point. There are various forms of CNC milling machines.

Although different types of CNC milling machines are different in composition, they have many similarities. Most of the CNC milling machines in the prior art are composed of a bed part, a milling head part, a workbench part, a transverse feed part, and a lift table part. It is composed of the cooling part and the cooling part. The cutting coolant reservoir used in the cooling part is set inside the machine bed. When the parts are processed, the parts to be processed are stabilized on the workbench, and the position of the parts is adjusted by the lifting table and the cross-feed part. Adjustment, through the movement of the milling head part on the bed part, the processing parts are processed. When the parts are processed in the milling head part, the processing of the parts can be completed by cooling the milling head through the cooling part, but in practice During the processing, the vibration between the milling head part and the parts often results in damage to the milling head or damage to the parts.

The reason why the CNC milling machine vibrates during the machining process is mainly due to the following two aspects. One is the looseness of the spindle. The spindle bearing will wear to a certain extent under long-term rotation. A certain gap is generated. If the gap of the spindle bearing is too large and the vibration amplitude of the milling head exceeds the specified range, the spindle bearing needs to be replaced. The second is that the parts are loose. The first reason for the looseness of the parts is that the workbench is not stable. The position of the part, the second main reason is that because the lifting table part and the infeed part of the CNC milling machine in the prior art mostly realize the movement of the position of the part through the cooperation of a single screw rod and nut, the traditional screw rod The gap between the nut and the nut is relatively large, and it is not suitable to stabilize the position of the workbench. The vibration of the workbench will cause the parts to vibrate, which will affect the processing and production of the parts. To solve the vibration problem, we propose an anti-vibration device for CNC milling machine.
