Photographing and positioning type metal plate punching device

[0011] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0012] see figure 1 and figure 2 The present invention includes a punching drive device 1, an upper template 2 and a punching head 3. It also includes a clamping device and a support seat 7 located below the punching head 3. The clamping device includes a symmetrically arranged clamping block 6 that clamps The holding block 6 is of an L-shaped structure, with a detection mark 8 on its upper end surface, and the workpiece 10 is clamped between the opposed clamping blocks 6; the clamping block 6 is mounted on the first bracket 12 by means of a screw shaft 4, the screw shaft The outer end of 4 is connected to the handle 5; the support seat 7 is placed below the position of the processing hole of the workpiece 10, and the support seat 7 has a through punching groove 71 for punching and blanking; the upper template 2 and the A photographing positioning device 9 is provided between the workpieces 10, and the photographing positioning device 9 includes a camera 94 installed at the end of the rotating rod 93, and the camera 94 is used to photograph the distance between the detection marks 8 on the upper end of the opposite clamping block 6; The rod 93 is rotatably connected to the second bracket 92, the end of the rotating rod 93 is provided with a handle 91; the front side of the upper template 2 is equipped with an indicator light 11 and a display screen 13, an indicator light 11, a display screen 13 and a camera 94 Connected to the control unit 15 respectively. The control unit 15 includes a comparison module 14 and a control module 16. The comparison module 14 compares the photo of the camera 94 with the standard photo 17, and the control module 16 transmits the adjustment information to the display screen 13 according to the comparison result; The indicator 11 includes a red light and a green light: when the comparison result is that the two photos are the same, the green light of the indicator 11 is on, otherwise the red light is on.

[0013] When the workpiece 10 is installed in the present invention, the camera 94 first takes a standard photo 17, that is, the position of the detection mark 8 on the opposite clamping block 6 in the standard state; the workpiece 10 is placed between the opposite clamping blocks 6 ; Rotate the hand grip 91 to place the camera 94 at the end of the rotating rod 93 directly below the punching head 3; turn the handle 5 to adjust the clamping block 6 to initially adjust the processing position of the workpiece 10, start the camera 94 to take pictures The camera 94 compares the photo taken with the standard photo 17 through the comparison module 14 of the control unit 15. The control module 16 sends the comparison result to the display screen 13 to prompt the operator to further adjust the processing position of the processed part 10; When there is no difference between the two, the control module 16 activates the green light of the indicator 11 to complete the positioning of the workpiece 10; rotate the handle 91 to rotate the camera 94 around the second bracket 92 by 180 degrees, leaving a punching space for the punching head 3.

[0014] In the present invention, the control unit 15, the comparison module 14, the control module 16, and the indicator light 11 are all existing technologies.

[0015] The invention adjusts the processing position of the workpiece through the photographing positioning device and the clamping block, and has a simple structure and low cost; adopts image contrast processing to display adjustment information in real time, and is easy to operate; and the setting of a support block can prevent the entire workpiece from being processed It is deformed, and the set punching groove is convenient for punching and blanking.

[0016] The above description is an explanation of the invention, not a limitation of the invention. For the scope of the invention, please refer to the claims. The invention can be modified in any form without departing from the spirit of the invention.
