Technical Field

[0001] This utility model relates to the field of fan shaft processing technology, specifically a drum-shaped chuck for a fan shaft processing machine tool. Background Technology

[0002] The fan shaft is the shaft in a fan that transmits power or carries the impeller. It typically consists of several components, including bearings and bearing housings, shaft end covers, and shaft seals. The main function of the fan shaft is to transmit torque, connect the fan blades to the fan base, and ensure the normal operation of the fan.

[0003] Fan shafts are made from a variety of materials, commonly including carbon steel, alloy steel, stainless steel, and aluminum alloy. Different materials can be selected based on the specific application requirements. During machine processing, the fan shaft needs to be secured using a chuck.

[0004] For example, a machine tool chuck accessory with application number 202221433091.4 that is easy to disassemble allows for easy removal of the chuck by simply pulling outwards on the elastic rod to disengage it from the chuck hole. This facilitates disassembly and cleaning, helping to maintain chuck cleanliness and ensure machining quality. However, this device still has certain drawbacks.

[0005] When fixing the workpiece, the clamping rods need to be rotated sequentially to clamp and fix the workpiece. The operation is cumbersome and laborious. In addition, the height of the chuck cannot be adjusted, resulting in low applicability.

[0006] Therefore, we propose a drum-shaped chuck for a fan shaft machining machine tool to solve the problems mentioned above. Utility Model Content

[0014] With the above structural design, when the left and right threaded rods rotate, they can drive the first slide bar and the second slide bar to move relative to each other. The first slide bar and the second slide bar drive the connecting bar to move relative to each other. The connecting bar drives the clamping block to move relative to each other. The clamping block clamps and fixes the fan shaft.

[0015] Preferably, the movable block has a "T" shaped structure design, and a guide rod is installed on the upper right side of the movable block.

[0016] With the above structural design, the movable block can move up and down along the guide rod when subjected to force, and the guide rod plays a guiding role in the up and down movement of the movable block.

[0017] Preferably, the guide rod and the ball screw are parallel to each other, and the movable block is slidably connected to the guide rod.

[0018] With the above structural design, the servo motor is started, and the servo motor drives the ball screw to rotate through the output shaft. The ball screw drives the movable block to move up and down, thereby driving the chuck mechanism above to move up and down, which makes it easier to adjust the height of the chuck mechanism, making it more convenient to process the fan shaft.

[0019] Preferably, the ball screw and the movable block form a sliding connection structure, and a groove is provided on the support frame, with the movable bar slidably connected to the groove.

[0020] With the above structural design, when the movable block moves up and down under force, the movable bar on the left side of the movable block can move up and down along the slide groove, thereby providing a further limiting and guiding function for the movable block. At the same time, when the movable block moves up and down, the counterweight on the left side of the movable block can balance the movable block, making the movable block more stable when moving up and down.
