[0018] Example: A clamping device for laser cutting of hardware parts, such as Figures 1-3 As shown, the device includes an operating table 1. The end face of the operating table 1 is equipped with an adjustment component 101 and a clamping component arranged opposite to each other. A laser cutting head 104 is arranged in the middle of the operating table 1. The adjustment component 101 includes a chuck 102 and a rotating head 103. The rotating head 103 has a built-in motor, and the output end of the motor is connected to the chuck 102.

The mounting frame 2 is fixed to the operating table 1 and is located on the opposite side of the adjustment component 101. The lower clamping plate 5 is fixed to the bottom of the mounting frame 2. An electric slide rail 3 is arranged on the inner side of the mounting frame 2. The upper clamping plate 4 is connected between the electric slide rails 3. By activating the electric slide rails 3, the upper clamping plate 4 can be moved down. The upper clamping plate 4 and the lower clamping plate 5 have notches on the opposite sides. The notches can limit and clamp the hardware located in the chuck 102.

[0019] like Figure 3 As shown, it also includes a drive mechanism, which includes a base 7, a connecting plate 8, a guide rod 9, a return spring 91, a drive roller 10, and a servo motor 11. The base 7 is fixed to the operating table 1 and located between the mounting brackets 2. The guide rods 9 are slidably connected to both sides of the base 7. The connecting plate 8 is fixed to the upper end of the guide rod 9. The return spring 91 is connected between the base 7 and the connecting plate 8. The drive roller 10 is rotatably connected between the connecting plates 8. The servo motor 11 fixed to the connecting plate 8 supplies power to the drive roller 10.

[0020] like Figure 3As shown, it also includes a limit rod 12, which is fixedly connected to the upper clamping plate 4, and the lower end of the limit rod 12 can contact and push the connecting plate 8. When the upper clamping plate 4 moves downward to clamp and fix the end of the hardware, the upper clamping plate 4 pushes the connecting plate 8 downward through the limit rod 12, so that the driving roller 10 moves downward synchronously to disengage from the hardware. At this time, the lower clamping plate 5 will support the hardware. The upper clamping plate 4 and the lower clamping plate 5 clamp and fix the hardware. After cutting, the upper clamping plate 4 moves upward to release the clamping of the hardware. The connecting plate 8 moves upward under the action of the return spring 91. The driving roller 10 moves upward synchronously and supports the hardware. At this time, the servo motor 11 is started to drive the driving roller 10 to rotate. The driving roller 10 will drive the hardware to discharge under the action of friction.

[0021] As shown in the Figure 2 It also includes a rubber pad 13, a ball 14 and a brush 15. The driving roller 10 is externally provided with the rubber pad 13. The opposite sides of the upper clamping plate 4 and the lower clamping plate 5 are provided with the ball 14. The opposite sides of the upper clamping plate 4 and the lower clamping plate 5 are provided with the brush 15.

The controller 6 is connected with the rotating head 103, the electric sliding rail 3 and the servo motor 11. The controller 6 is externally provided with the protective shell 16.

[0023] Working principle: The chuck 102 of the adjusting assembly 101 adopts a half-ring clamping mode arranged oppositely. A spring is connected between the two half-rings, which can be extended to achieve the effect of clamping the hardware. The hardware is passed between the clamping assemblies. The servo motor 11 is started to drive the hardware to move leftward and be fixed at the chuck 102 through the driving roller 10. Then the electric sliding rail 3 is started to control the upper clamping plate 4 to move downward through the controller 6. The driving roller 10 moves downward synchronously to disengage from the hardware. At this time, the lower clamping plate 5 will support the hardware. The upper clamping plate 4 and the lower clamping plate 5 clamp and fix the hardware. After cutting, the upper clamping plate 4 moves upward to release the clamping of the hardware. The connecting plate 8 moves upward under the action of the return spring 91. The driving roller 10 moves upward synchronously and supports the hardware. At this time, the servo motor 11 is started to drive the driving roller 10 to rotate. The driving roller 10 will drive the hardware to discharge under the action of friction. Thus, the cutting effect is achieved. Compared with the existing cutting method which only fixes one end of the hardware, the device can conveniently clamp both ends of the hardware and then cut it. The hardware is kept fixed during cutting, which ensures the accuracy of cutting. At the same time, the driving mechanism is arranged to realize the rapid discharge of the hardware.
