Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, and specifically relates to a milling head device for an electric motor processing milling machine. Background Art

[0002] A milling machine is a machine tool mainly used for milling workpieces. It usually takes the rotary motion of the milling cutter as the main motion, and the movement of the workpiece and the milling cutter as the feed motion. The milling machine can machine planes, grooves, and can also machine various curved surfaces, gears, etc. In electric motor processing, the milling machine can be used to machine various parts of the electric motor, such as the housing, end cover, bearing seat, etc. The milling head is one of the main accessories of the milling machine. Its spindle can rotate in two mutually perpendicular planes, and can not only complete vertical milling and horizontal milling work, but also perform milling of various angles, multiple surfaces, multiple edges, and multiple grooves during a single clamping of the workpiece.

[0003] The common milling head device for an electric motor processing milling machine is usually composed of structures such as a spindle, a spindle housing, a gearbox, a cooling system, a lifting sleeve, and a positioning guide plate. The spindle housing and the gearbox and other structures drive the spindle and the milling cutter to rotate, the lifting sleeve and the positioning guide plate drive the milling cutter to descend and adjust, and process the workpiece, and then the cooling system cools it down. This is the structure and usage method of the common milling head device for an electric motor processing milling machine. When the traditional milling head device for an electric motor processing milling machine is in use, the angle of its milling head cannot be controlled, resulting in the inability to complete multi-angle and multi-directional work, and it is not convenient to use. For example, in the milling head device for fine machining of wear-resistant alloy parts with the patent number CN206643416U, three milling cutters can be installed on the milling head at the same time, enabling simultaneous multi-angle operation, with higher efficiency and more convenient use. However, in this way, due to the fixed installation position on the milling head, and the angles of the three milling cutters on the milling head are fixed and cannot be adjusted, when processing the workpiece, the processing angle is fixed, resulting in the inability to perform comprehensive angle processing on the workpiece. Therefore, a milling head device for an electric motor processing milling machine is proposed. Summary of the Utility Model
