Clamping mechanism for internal grinding machine

The clamping mechanism for the internal grinding machine comprises a guide transverse plate, an adjusting sliding groove is formed in the top end of the guide transverse plate, an adjusting sliding block is connected into the adjusting sliding groove in a sliding mode, an installation transverse plate is fixedly connected to the top end of the adjusting sliding block, and a servo motor is installed at the top end of the installation transverse plate. The cylindrical workpiece grinding device can be arranged in an internal grinding machine, the adjusting screw rod moves upwards from the positioning screw hole by rotating the adjusting rotary handle, the positioning block is separated from the connecting sliding block, then the supporting transverse plate can be lifted, a cylindrical workpiece to be ground is placed at the top end of the material placing plate, then the adjusting rotary handle can be rotated, and the cylindrical workpiece can be ground. And the adjusting screw rod moves downwards from a positio
