Description

Technical Field

[0001] The utility model relates to the technical field of turning power heads, in particular to a turning power head for a milling machine which can digitally control the radial movement of a turning tool. Background Art

[0002] The turning power head of a milling machine is a special device installed on a milling machine. It can expand the processing capacity of the milling machine, enabling it to perform a variety of processing operations such as turning, drilling, and milling. The advantage of the turning power head of a milling machine is that it can perform a variety of processing operations on the same equipment, reducing the downtime caused by changing machine tools and improving production efficiency. Therefore, it is widely used in the field of mechanical processing, especially in the automotive, aerospace, mold manufacturing and other industries. It is particularly useful for the processing of complex parts. The turning power head for a milling machine with digitally controlled radial movement of the turning tool is an advanced machine tool accessory, which allows the milling machine to realize radial movement of the turning tool during the processing process, thereby expanding the processing capacity of the milling machine.

[0003] The common digitally controlled milling machine turning power head consists of a servo motor, a lead screw, a guide rail, a control system and a feedback system. The CNC system is responsible for sending precise control signals, monitoring the position and speed of the turning tool, and ensuring that the turning tool moves according to the predetermined path and speed. In order to improve the control accuracy, it is usually equipped with a position sensor or encoder as a feedback element to monitor the position of the turning tool in real time and feed the information back to the CNC system to form a closed-loop control to ensure the movement accuracy of the turning tool. The servo motor can receive signals from the CNC system and control the movement of the turning tool along the radial axis according to the preset program or manually entered data.

[0004] However, in order to protect the tool and improve the machining accuracy, this method will simultaneously spray chip fluid during milling machine machining to reduce the temperature of the tool. The chip fluid is generally sprayed from a hose at a high pressure by adjusting the spray angle before machining. However, during machining, the turning power head needs to move in different directions, and the turning power head will vibrate during high-speed rotation and cutting, which will cause the chip fluid pipeline to loosen and then shift, resulting in the chip fluid being unable to be effectively sprayed on the surface of the tool and the workpiece, thereby increasing the friction between the tool and the workpiece and raising the temperature, accelerating the wear of the tool, and the worn tool will cause scratches, burns or other defects on the machined surface, reducing the machining quality and failing to meet the working requirements of the turning power head. For this reason, a turning power head for a milling machine that can digitally control the radial movement of the turning tool is proposed. Summary of the invention
