DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] See Figure 1 A CNC pneumatic clamp includes a clamp mainboard 1 and a cylinder 2. In this embodiment, the clamp mainboard is used to be installed in mechanical equipment for positioning, and the cylinder is a conventional structure of the prior art and is simply used.

[0027] In actual application, a chuck seat 3 is provided on the clamp main board, and the chuck seat and the cylinder are arranged on both sides of the clamp main board. A chuck driving cone sleeve 4 is provided in the chuck seat, and a chuck structure 5 is provided in the chuck driving cone sleeve. The chuck driving cone sleeve is sleeved on the chuck structure and can be translated on the chuck structure; the chuck driving cone sleeve is mainly through the conical structure, and when it is translated on the chuck structure, the chuck structure can clamp the workpiece, and its translation distance can achieve the stability and effectiveness of clamping.

[0028] Furthermore, in actual use, the cylinder's main shaft is connected to a cylinder connecting plate 6, which is connected to the chuck drive taper sleeve via a taper sleeve connecting pin 7. This structure allows the cylinder to drive the chuck drive taper sleeve to translate on the chuck structure via the taper sleeve connecting pin, ensuring the chuck structure's effective clamping. During use, the cylinder's main shaft expands and contracts, causing the chuck drive taper sleeve to translate on the chuck structure, clamping the chuck structure to position the workpiece.

[0029] In this embodiment, a connecting pressure channel 8 is provided in the middle of the clamp main plate, chuck seat, and chuck structure. A rod 9 is retractably disposed within the pressure channel. In actual use, the rod can be connected to a cylinder or a separate drive structure. The rod retracts within the pressure channel, causing the ends of the chuck structure to expand and position the workpiece. This is primarily used to expand the chuck structure and complete the tensioning and positioning of the workpiece.

[0030] In actual use, the chuck structure comprises a first chuck half 51 and a second chuck half 52. The outer walls of the first and second chuck halves are provided with inclined surfaces. Furthermore, the inner wall of the chuck driving sleeve is provided with a tapered surface. During assembly, the tapered surface abuts against the inclined surface. In this embodiment, the chuck structure contacts the tapered surface via the inclined surface, allowing the chuck structure to clamp and position the workpiece 13 when the chuck drives the sleeve to translate.

[0031] In actual application, the pressure channel is a truncated cone-shaped channel; the diameter of the rod body is smaller than the diameter of the large hole end of the truncated cone-shaped channel and larger than the diameter of the small hole end of the truncated cone-shaped channel. This structure ensures that the chuck structure is tightened outward when the rod body moves, completing the positioning and connection of the workpiece.

[0032] In actual use, a locking nut 10 is provided on the outside of the chuck seat; a connecting nut 11 is provided on the clamp main plate, and the end of the chuck structure is positioned on the clamp main plate through the connecting nut; and the connecting nut and the locking nut are respectively located on either side of the clamp main plate, with a nut connecting rod 12 provided between the connecting nut and the locking nut, thus ensuring a stable and reliable connection.

[0033] Furthermore, in this embodiment, the overall structure of the first half clamp and the second half clamp is a cylindrical structure.

[0034] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the cylinder, the chuck driving cone sleeve and the chuck structure are provided, and the cylinder connecting plate is connected to the chuck driving cone sleeve through the cone sleeve connecting pin, which not only improves the convenience of the clamping operation, but also ensures the stability and reliability of the clamping of the workpiece through the chuck structure, which is conducive to improving the precision and efficiency of workpiece processing, and has strong applicability and good practicality;

[0035] At the same time, a top pressure channel and a rod body are provided, so that the chuck structure can be expanded outward by controlling the rod body as needed to complete the tightening operation of the workpiece, meeting the clamping processing requirements of different workpieces, improving its scope of application, and having strong practicality.

[0036] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0037] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
