Description

Technical Field

[0001] The utility model relates to the technical field of tubular workpiece processing operating tables, in particular to a tubular workpiece clamping operating table. Background Art

[0002] When processing a tubular workpiece, the processing operation is usually performed on a corresponding operating table. In addition, in order to ensure that the tubular workpiece is processed more smoothly on the operating table and that the position of the tubular workpiece does not shift during the processing, a clamping assembly for clamping the tubular workpiece is generally provided on the operating table. This type of clamping assembly generally works using a pneumatic cylinder or a hydraulic cylinder to drive the corresponding fixture to perform a clamping operation from top to bottom, thereby achieving the effect of clamping and fixing the tubular workpiece.

[0003] However, when using this type of clamping operation table, due to the tubular shape of the tubular workpiece, when clamping from top to bottom, the tubular workpiece is prone to rolling and slipping on the operation table, affecting the clamping effect. If the clamping force is too large, although it can achieve a good clamping and fixing effect, it is easy to deform the tubular workpiece due to excessive force, affecting the clamping effect and causing inconvenience to the user. In view of this, we propose a tubular workpiece clamping operation table. Utility Model Content
