Abstract

The utility model discloses a rotary type pressing plate end face cam clamping mechanism, and belongs to the technical field of machine tool clamp accessories. The utility model comprises six parts of a clamp body, a fixed shaft pin, a handle, an end face cam, a sliding rod and a pressing plate, and the use and movement principles are as follows: the handle is rotated anticlockwise to rotate the end face cam by a certain angle, the sliding rod which is in close contact with the end face cam is enabled to move upwards under the action of the inclined surface of the cam, and the pressing plate and the workpiece are enabled to press the workpiece at a contact point by utilizing the lever principle. When the handle is rotated clockwise, the slide rod moves downwards due to the fact that the inclined plane of the cam in contact with the slide rod is lowered, the press plate and the workpiece are lifted at the contact point under the action of gravity, and the workpiece is loosened. The rotary type pressing plate end face cam clamping mechanism can effectively solve the problems that an end face pressing clamp is not flat, and the operation of a pressing process of a general pressing plate is complex and the like.
