Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool with adjustable clamping angle. Background Art

[0002] At present, CNC machine tools can only clamp workpieces in a single manner when in use, and are not convenient for adjusting the angle of the workpiece according to processing requirements. Their scope of use is limited and cannot meet current usage needs.

[0003] According to a publicly disclosed CNC machine tool with adjustable clamping angle (Announcement No.: CN219094309U), the above application is provided with a first pin shaft seat, a second pin shaft seat, a clamp and an electric push rod. The thrust provided by the electric push rod is used to facilitate the first pin shaft seat to push the clamp to move, and then the second pin shaft seat is used to facilitate the electric push rod to move in an arc shape when it is extended and retracted. By providing a slide groove and a slider, the slide groove and the slider cooperate to facilitate left and right sliding.

[0004] However, in actual use of the above-mentioned equipment, it is generally necessary to adjust the flipping angle of the workpiece to facilitate processing on the other side. However, the existing clamping tools cannot limit and fix the adjusted angle during the process of flipping and adjusting the workpiece angle. The adjusted angle may be offset due to the change in the center of gravity of the workpiece, thereby having a certain impact on the subsequent processing accuracy. In view of this, we propose a CNC machine tool with adjustable clamping angle. Utility Model Content
