Description

Technical Field

[0001] This utility model relates to the technical field of additional milling head structures, specifically an additional milling head structure for machine tools. Background Technology

[0002] The machine tool's auxiliary milling head structure mainly consists of two parts: a vertical milling head and a rotary table. These two parts allow the spindle axis to rotate around the X and Y directions, thereby forming any required angle and expanding the machine tool's machining range. The milling head's spindle can rotate in two mutually perpendicular rotating planes, enabling it to not only perform vertical milling and planar milling operations, but also to perform multi-faceted, multi-edge, and multi-groove milling at various angles in a single setup.

[0003] As disclosed in the authorization announcement number CN222429389U, a CNC machine tool milling head structure includes a housing, characterized in that: a window is provided on the side of the housing, a sleeve is sleeved inside the housing, a main air passage is provided inside the sleeve, a second air passage is provided on the side of the main air passage near the bottom, a first pneumatic motor is provided at the other end of the second air passage, a first tool holder is provided on one side of the first pneumatic motor, a first pressure cap is rotatably installed on one side of the first tool holder, an air pipe is provided on the top of the housing, an air pipe connector is provided at the other end of the air pipe, and an air source is connected to the other end of the air pipe connector.

[0004] Although it allows air to enter the milling head through the air tube and then into the first pneumatic motor through the main air passage, the rotation of the motor drives the tool holder to rotate and process the product. When a tool change is needed, the spindle moves away from the workpiece and rotates 180° to complete the tool change without stopping the machine to disassemble the milling head. It is suitable for side milling work that requires tool changes, which can save processing time and improve work efficiency. It can perform side mechanical milling, solving the problem that traditional machine tools can only feed up and down. Moreover, the taper shank specification is the same as the taper shank of commonly used CNC machine tools, which allows the milling head to be installed on most CNC machine tool spindles. Furthermore, the taper shank housing can be detached from the inside of the milling head to install other models and specifications of taper shanks, making the milling head structure usable on various machine tools and greatly increasing the application range of the milling head structure.

[0005] However, this does not solve the problem that existing milling head structures of this type are generally not conducive to convenient rotation angle milling operations, making it inconvenient to easily rotate the milling head, affecting the working range, the efficiency of the milling head structure, and the convenience of changing the milling head.
