Automatic chamfering device for turbine blade rivet head

The invention discloses a steam turbine blade rivet head automatic chamfering device which comprises a base and a chamfering tool driving part, the chamfering tool driving part is installed on the base, the base is further provided with a workpiece clamp and a speed limiting mechanism, the workpiece clamp is connected to the base in a sliding mode, and the speed limiting mechanism is used for limiting the moving speed of the workpiece clamp. When the automatic chamfering device for the steam turbine blade rivet head is used, the blade with the rivet head is installed on the workpiece clamp, then the workpiece clamp is pushed to the chamfering tool driving piece, and under the action of the speed limiting mechanism, the rivet head is stably, flexibly and slowly close to and make contact with a chamfering tool driven by the chamfering tool driving piece, so that chamfering is completed. According to the automatic chamfering device for the steam turbine blade rivet head, the force exerting direction and force ca
