Detailed Description

The following describes the present invention with reference to the accompanying drawings and examples.

Referring to fig. 1, the original workpiece clamping device comprises a fixed table 1, a fixed backer 2, a pressing guide rail 3 and a pressing cylinder 4, wherein a workpiece 5 is placed on the fixed table 1 and clamped and fixed by the fixed backer 2 and the pressing cylinder 4, and the pressing cylinder 4 moves on the pressing guide rail 3.

Referring to fig. 2 and 3, the utility model discloses a numerical control clamping device, including workstation 6 and clamping mechanism 7, workstation 6 includes conveying platform 61 and fixed part 62, fixed part 62 and conveying platform 61 fixed connection. The clamping mechanism 7 comprises a pressing part 71, a lifting part 72 and a numerical control shaft 8, wherein the pressing part 71 is arranged on the conveying platform 61 relative to the fixing part 62, the pressing part comprises a pressing block 701 and a horizontal pressing cylinder 702, and the pressing block 701 is connected with the horizontal pressing cylinder 702. The workpiece 5 is placed in parallel between the fixing member 62 and the pressing member 71, and the workpiece 5 is clamped on the conveying table 61 by the fixing member 62 and the pressing block 701 of the pressing member 71.

The lifting component 72 is connected with the pressing component 71, and the pressing component 71 is driven by the lifting component 72 to lift above the conveying platform 61. The numerical control shaft 8 comprises a moving guide rail 81 and a moving part 82, the moving guide rail 82 is arranged in parallel with the conveying platform 61, the moving part 82 is arranged on the moving guide rail 81, and the moving part 82 is connected with the lifting part 72 through a connecting piece 9, so that the moving part 82 drives the lifting part 72 and the pressing part 71 to move on the conveying platform 61 simultaneously when moving on the moving guide rail 81.
