[0025] The clamping drive assembly is connected to the clamping assembly to drive the clamping assembly to clamp the workpiece;

[0026] The rotary drive assembly is connected to the rotary assembly to drive the rotary assembly to rotate, thereby driving the workpiece to rotate.

[0027] The annular workpiece clamping and rotating mechanism of the utility model can realize clamping and keep the centering of the workpiece during the rotation of the workpiece, and can realize the self-centering support and rotation of the annular workpiece with a large span. Example 2

[0028] like Figures 1 to 3 As shown, an annular workpiece clamping and rotating mechanism comprises a workpiece clamping mechanism and a workpiece rotating mechanism, wherein the workpiece clamping mechanism comprises a clamping drive assembly and a clamping assembly 3, and the workpiece rotating mechanism comprises a rotating drive assembly and a rotating assembly;

[0029] The clamping drive assembly is connected to the clamping assembly to drive the clamping assembly to clamp the workpiece;

[0030] The rotary drive assembly is connected to the rotary assembly to drive the rotary assembly to rotate, thereby driving the workpiece to rotate.

[0031] In this embodiment, Figure 1 and Figure 3 As shown, the workpiece clamping mechanism and the workpiece rotating mechanism each include multiple groups, and three groups are used as an example for description in this embodiment, wherein each group includes a workpiece clamping mechanism and a workpiece rotating mechanism.

[0032] In this embodiment, Figure 1 and Figure 3 As shown, the clamping drive assembly includes a clamping drive motor 1 and a transmission mechanism 7. The clamping drive motor 1 is connected to the clamping assembly through the transmission mechanism 7, and the clamping drive motor 1 drives the clamping assembly to perform corresponding clamping operations. Among them, the transmission mechanism 7 adopts a driving wheel, a driven wheel and a synchronous belt connection structure.

[0033] In this embodiment, Figure 3 As shown, the clamping assembly includes a screw slide rail mechanism 9, a clamping guide rail 8 and a clamping wheel 2. The screw slide rail mechanism 9 adopts a screw slider structure, and the clamping wheel 2 is installed on the slider, and the slider performs reciprocating linear motion with the clamping guide rail 8 as the motion trajectory. Among them, the clamping wheel 2 has a certain height and can rotate by itself, so that when the workpiece 4 rotates, it can be clamped by each group of clamping wheels 2 at the same time.

[0034] In this embodiment, Figure 1 and Figure 3 As shown, the rotary drive assembly includes a rotary drive motor 6 and a transmission mechanism 7. The rotary drive motor 6 is connected to the rotary assembly through the transmission mechanism 7, and the rotary assembly is driven by the rotary drive motor 6 to perform corresponding rotation operations.

[0036] The working principle of the clamping and rotating mechanism of the utility model is:

[0037] Firstly, the number of workpiece clamping mechanisms and workpiece rotating mechanisms is determined according to the size of the workpiece 4, and then each group of workpiece clamping mechanisms and workpiece rotating mechanisms is distributed in a circumferential direction.

[0038] Then place the workpiece 4 on the workpiece clamping mechanism and the workpiece rotating mechanism. First, the clamping drive motors 1 in each group are started synchronously, so that the clamping wheels 2 are clamped inward synchronously. When the clamping wheels 2 contact the outer wall of the workpiece 4, the clamping drive motors 1 in each group are stopped.

[0039] Finally, the rotary drive motors 6 in each group are synchronously started, so that the rotary drive rollers 5 in each group rotate in the same direction, thereby driving the workpiece 4 to rotate synchronously, and then the flaw detection mechanism is started to perform flaw detection on the workpiece 4.

[0040] The annular workpiece clamping and rotating mechanism of the utility model can realize clamping and keep the centering of the workpiece during the rotation of the workpiece, and can realize the self-centering support and rotation of the annular workpiece with a large span.
