Description

Technical Field

[0001] This utility model relates to the field of compressor processing equipment technology, and in particular to a milling device for compressor processing. Background Technology

[0002] As a key component of new energy vehicles, scroll compressors are characterized by their high efficiency and energy saving. In medium and low temperature applications, they have a volumetric efficiency that is more than 30% higher than that of traditional piston compressors. They also operate smoothly with low noise and vibration, reducing their environmental impact. As a highly efficient and energy-saving fluid machine, they occupy an important position in the refrigeration and air conditioning fields.

[0003] In compressor manufacturing, the process typically involves casting followed by milling on a milling machine. Since the compressor casing and scroll plate are curved, milling requires an angled feed. However, existing milling cutters generally only have Z-axis vertical movement. When angled feed is needed, the workpiece must be released and its clamping angle adjusted, resulting in low efficiency and requiring highly skilled angle control. Current technologies utilize dedicated fixed molds or machining centers. However, dedicated fixed molds still require replacement and are inflexible, while machining centers have higher procurement costs, increasing overall processing costs and indicating room for further improvement.

The milling machine worktable is disposed above the processing base. A first fixed seat is fixedly connected to one side of the upper center of the milling machine worktable, and a second fixed seat is fixedly connected to the upper center of the milling machine worktable away from the first fixed seat. Connecting seats are rotatably connected to the upper opposite sides of the first and second fixed seats. A rotating swing table is disposed between the first and second fixed seats. An electric rotary table is fixedly connected to the upper center of the rotating swing table. A three-jaw chuck is fixedly connected to the upper rotating end of the electric rotary table.

[0006] According to the milling device for compressor processing, the upper sides of the rotating swing table are fixedly connected to corresponding connecting seats.

[0007] According to the milling device for compressor processing, the three-jaw chuck is a commercially available self-centering three-jaw hydraulic chuck.

[0008] According to the milling device for compressor processing, the output shaft of the servo motor passes through the first fixed seat and is fixedly connected to the connecting seat.
