Clamping mechanism suitable for clamping flat surface or curved surface

Abstract

The invention discloses a clamping mechanism suitable for clamping a flat surface or a curved surface. The clamping mechanism comprises a workbench, wherein two support columns are arranged at the top of the workbench and a plurality of leakage holes are formed in the top of the workbench; a drive mechanism is arranged on the support columns; a drive shaft of the drive mechanism is inserted into the support columns in a penetrating manner; a connection rod is arranged at the tail ends of the support columns; one end of the connection rod is connected with the drive shaft, and a movable shaft is arranged at the other end of the connection rod; a first clamping block is arranged on the movable shaft; a thread hole is formed in the first clamping block; a screw is arranged in the thread hole; a second fixing block is arranged on the screw; fixing blocks are arranged at the four corners of the top of the workbench; an air blowing pipe is arranged on each fixing block; an air blower and a drawer are further arranged on the side surface of the workbench; the drawer is manufactured from a magnetic material, and the inside of the drawer communicates with the leakage holes; and the air blower is connected with the air blowing pipes. The clamping mechanism disclosed by the invention is capable of fixing a workpiece with the flat surface or the curved surface, and capable of uniformly recovering and storing the chippings generated during a machining process, thereby preventing the chippings from scratching operating personnel.

Description

technical field [0001] The invention relates to the field of workpiece processing devices, in particular to a clamping mechanism suitable for clamping plane or curved surfaces. Background technique [0002] Fixture is a commonly used tool in the process of machining. It is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position for construction or inspection. It is used to fix the material or part to be processed, to ensure that it will not move and shift during the processing, and to avoid the deviation of the object to be processed from affecting the precision and accuracy of the processing operation. In a broad sense, in any process of the processing process, the device used to quickly, conveniently and safely install the workpiece can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Existing fixtures, except some special fixtures spe...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing clamps can only clamp a single plane or curved surface, which brings a lot of inconvenience to users and reduces the processing efficiency. The unique clamping mechanism can not only clamp the flat workpiece, but also clamp the curved surface workpiece
