The invention discloses an oscillating head with a temperature control structure, relates to the technical field of numerical control processing equipment, and includes an A-axis and an electric spindle, the A-axis is connected to the electric spindle by transmission, and the electric spindle is connected to the A-axis A first temperature control structure is arranged between them, and a second temperature control structure and a third temperature control structure are arranged on the A axis. In the present invention, a first temperature control structure is provided between the electric spindle and the A-axis, and a second temperature-control structure and a third temperature-control structure are provided on the A-axis, respectively aiming at the heat sensitive point of the swing head, the heat source of the swing head and the heat source Conducting heat conduction and temperature control on the conduction part, achieving the purpose of reducing the internal temperature rise and thermal deformation of the swing head, and solving the problem that the original swing head has a large thermal deformation that affects the processing accuracy. The structure of the invention is relatively simple, the modification of the original structure is small, the temperature of multiple parts is controlled simultaneously, the cost is low, the temperature control effect is good, and the thermal deformation is reduced.

Description

technical field [0001] The invention relates to the technical field of numerical control processing equipment, in particular to a swing head with a temperature control structure. Background technique [0002] The swing head integrates precision machinery manufacturing technology, hydraulic drive technology, and signal line rotary butt winding technology, and is one of the key components of large machine tools. During the operation of the existing swing head torque motor, the internal temperature of the swing head is likely to rise rapidly due to factors such as power loss, friction, and closed internal space, so that the output torque of the torque motor will drop significantly. In addition, the heat will cause thermal deformation of the swing head, affecting the machining accuracy of the machine tool. Therefore, cooling technology is one of the key technologies of swing head. For the thermal deformation of the swing head, the existing solutions include: using cooling pipe...
