Technical Field

[0001] The utility model relates to the technical field of shaft processing, and specifically discloses a support bracket for shaft processing. Background Technique

[0002] A shaft is one of the important parts of a machine. All kinds of transmission parts that make rotary motion transmit motion and power through the shaft. Usually, the shaft, together with bearings and a frame, supports the rotary parts, and then realizes the transmission of motion and power through a coupling or a clutch.

[0003] Shaft parts are used in a large amount in the mechanical field, providing assistance for various mechanical transmissions. Shaft parts need to be polished and drilled on their surfaces during production, and then brackets are needed to lift them during processing to facilitate subsequent processing.

[0004] However, the existing support brackets for shaft processing are all fixed structures. Therefore, for shaft parts of different sizes, different-sized brackets need to be replaced for processing, which is time-consuming and laborious. Therefore, a support bracket for shaft processing is needed to solve this problem. Content of the Utility Model

Second lead screws are rotatably connected to the front and rear end surfaces inside the two U-shaped plates. Both ends of the outer walls of the two second lead screws are threadedly connected with sliders. Connecting shafts are fixedly connected to the outer walls of the four sliders. The four connecting shafts are respectively slidably connected to the two arc-shaped chutes. Support wheels are rotatably connected to the other ends of the four connecting shafts.

[0007] In order to facilitate driving the first lead screw to rotate, as a preferred support bracket for shaft processing of the utility model, a first servo motor is installed on the left end surface of the left side plate, and the output end of the first servo motor is fixedly connected to the first lead screw.

[0008] For the convenience of driving the second lead screw to rotate, as an optimization of the support bracket for shaft machining of the present utility model, second servo motors are installed on the front end faces of the two U-shaped plates, and the output ends of the two second servo motors are respectively fixedly connected to the two second lead screws.

[0009] For the convenience of the stable left-right sliding of the sliding plate, as an optimization of the support bracket for shaft machining of the present utility model, two symmetrically distributed sliding rods are fixedly connected between the two side plates, and the two sliding plates are respectively slidably connected to the two sliding rods.

[0010] For the convenience of the relative or opposite movement of the two sliding plates and the two sliders, as an optimization of the support bracket for shaft machining of the present utility model, both the first lead screw and the second lead screw are bi-directional lead screws.

[0011] For the convenience of controlling the device, as an optimization of the support bracket for shaft machining of the present utility model, a controller is provided on the outer wall of the left side plate.
