Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a CNC machine table clamp comprises two fixing seats which are identical in structure and are mirror images up and down, wherein a plurality of first air cylinders 1 are fixed on the bottom surfaces of the fixing seats below, output shafts (namely piston rods) of the first air cylinders 1 upwards penetrate through the fixing seats below and are connected with the bottoms of the fixing seats above, the fixing seats below comprise a bottom plate 2, a movable plate 3, a circular table 4 and a plurality of second air cylinders 5, the circular table 4 is located in the middle of the surface of the bottom plate 1, the movable plate 3 is stacked on the bottom plate 2, circular openings 6 are formed in the positions, corresponding to the circular table 4, of the movable plate 3, the shape and the size of each circular opening 6 are identical to those of the circular table 4, a plurality of second air cylinders 5 are fixed at the bottom of the bottom plate 2, and the output shafts of the second air cylinders 5 upwards penetrate through the bottom plate 2, and is connected to the bottom of the movable plate 3, and the thickness of the movable plate 3 is the same as the height of the circular truncated cone 4.

Fig. 1 is a schematic view of the clamp for clamping a spherical workpiece, in this case, two sides of the spherical workpiece are clamped by a circular truncated cone 4, and then the movable plate 3 is pushed by the second cylinder 5 to separate from the bottom plate until the circular opening 6 on the movable plate 3 is hooped on the spherical workpiece, and the spherical workpiece is hooped on two sides by the circular openings 6 on the movable plates 3 on two sides, so as to realize clamping and fixing.

Fig. 2 is a schematic view of the clamp for clamping a planar workpiece, in this case, the movable plate 3 is attached to the bottom plate 2, the circular truncated cone 4 is located in the circular opening 6 and fills the circular opening 6, and the surface of the movable plate 3 is a complete plane, so as to stably clamp the planar workpiece.

In one embodiment, four first cylinders 1 are provided and are dispersedly fixed on the bottom surface of the bottom plate 2 on the fixing base below.

In one embodiment, the second cylinder 5 is located inside the first cylinder 1 on the bottom surface of the bottom plate 2.
