Detailed Description

The utility model is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 2 to 4, a clamping spindle rotating module comprises a mounting bracket 1, a spindle sleeve 2 movably supported in the mounting bracket 1, and a pull rod 3 arranged in the spindle sleeve 2, a pull rod seat 4 is fixed at the upper end part of the pull rod 3, a limit hole 4a for a shaft of a workpiece to pass through is arranged in the pull rod seat 4, a workpiece placing seat 5 is fixedly arranged at the end part of the rotating shaft sleeve 2, a positioning hole 5a which is aligned with the limiting hole 4a is arranged on the workpiece placing seat, wherein the upper end part of the rotating shaft sleeve 2 is provided with a horn-shaped opening, the corresponding pull rod seat 4 has a shape matched with the horn-shaped opening, a fixed frame 6 is fixedly arranged below the pull rod 3, a pull rod motor 8 is fixedly arranged at the bottom of the fixed frame 6, the pull rod motor 8 is fixedly connected with the lower end of the pull rod 3, and a rotating shaft sleeve motor 7 for driving the rotating shaft sleeve 2 to rotate is fixedly arranged on one side of the fixing frame 6.

In the structure, the long shaft of the turbine workpiece passes through the positioning hole 5a and the limiting hole 4a which are aligned between the workpiece placing seat 5 and the pull rod seat 4, at the moment, the pull rod motor 8 drives the pull rod 3 to move downwards, the pull rod 3 drives the pull rod seat 4 to move downwards along the horn-shaped opening at the upper end part of the rotating shaft sleeve 2, and the inner wall of the horn-shaped opening extrudes the pull rod seat 4, so that the long shaft at the lower end of the turbine workpiece is firmly fixed in the limiting hole 4a of the pull rod seat 4.
