Background The existing fixture rotating device needs time and labor consumption for manually adjusting the fixture, needs to be assembled at different angles, needs to rotate after clamping, is complex in operation, and is easy to produce misoperation during manual operation, such as the problems of unknown rotating direction, insufficient clamping force and the like, so that a new fixture rotating device becomes a problem which needs to be solved by a person skilled in the art. Disclosure of utility model The utility model provides a tool clamp rotating device, which is used for clamping a workpiece and then rotating, and comprises the following components: A support plate; The rotating assembly is arranged at the bottom end of the supporting plate and drives the supporting plate to rotate; the electromagnetic chuck is positioned at the top end of the supporting plate and is used for providing electromagnetic attraction force; The clamping assemblies are positioned at the top ends of the electromagnetic chucks and used for clamping workpieces, and the clamping assemblies are connected with the electromagnetic chucks. Optionally, the electromagnetic chuck is cross structure, electromagnetic chuck is inside to set up iron core and coil, and the circular telegram back electromagnetic chuck adsorbs press from both sides the dress subassembly and form fixedly. Optionally, the cross structure of electromagnetic chuck has seted up the spout respectively, the spout with press from both sides dress subassembly looks adaptation. Optionally, clamping assembly is provided with four, sets up respectively electromagnetic chuck's four directions of cross structure, clamping assembly includes support, slider and elasticity contact pin, the slider sets up the bottom of support, elasticity contact pin sets up on the support. Optionally, the support sets up to L type, four the support orientation electromagnetic chuck's cross port of cross structure slides, slide on the spout and to the adaptive position back to the work piece formation centre gripping. Optionally, the elastic contact pin is provided with a plurality of, and densely arranged is in the support is towards the cross port of electromagnetic chuck's cross structure. Optionally, the elasticity contact pin has backplate, elastic part and supporting part, the backplate with a plurality of supporting hole is seted up to the position of elastic part looks adaptation, the elastic part is installed the inside of supporting hole, the one end of elastic part with the bottom of supporting hole is connected, the other end with the supporting part is connected, the one end of supporting part with the elastic part is connected, and the other end is used for contacting the work piece. The beneficial effects of the application are as follows: 1.
