The foregoing and other features and advantages of the invention will be apparent from the following, more particular, description of the invention, as illustrated in the accompanying drawings, in which embodiments described are merely some, but not all embodiments of the invention.
The invention provides a self-aligning stamping device. Traditional stamping device relies on manual positioning, and manual material and blowing are got out, and consequently the positioning effect is very inaccurate, influences the punching press quality on panel surface to rely on manual positioning, operating personnel need stretch into the stamping device with the hand and operate, probably lead to the potential safety hazard because misoperation. According to the invention, the coordinates of the center of the cross mark are calculated by sensing the coordinates of the two ends of the cross mark and the length of the cross mark, which are sunken in the surface of the plate, and the control system controls the pressing head to align with the cross mark for stamping. The structure of the self-aligning punching device of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, the present invention is a self-aligning stamping device for stamping a sheet 5 on a table 1, the stamping device comprising a ram 3 mounted on a headstock 2. The system further comprises a distance sensor 8, a distance calculator 4, a processing module 6 and a control module 7. The distance sensor 8 can continuously sense the vertical height between the distance sensor 8 and the plate 5, when the vertical distance between the distance sensor 8 and the plate 5 is changed, the distance sensor 8 sends out an electric signal, the distance calculator 4 starts to work after receiving the electric signal sent out by the distance sensor 8, namely, starts to measure the horizontal distance of the vertical distance change sensed by the distance sensor 8, and the processing module 7 calculates the distance from the end part of the cross mark to the center of the cross mark according to the measured distance of the cross mark, and then calculates the center coordinate of the cross mark according to the obtained coordinates of the two end parts of the cross mark; and then the control module 7 controls the pressing head 3 to align with the center of the cross mark for punching according to the center coordinate of the cross mark obtained by the processing module 6.
The distance reactor 8 sends out two electric signals when passing through the cross mark, namely, the vertical distance is changed from the plate 5 to the concave position of the cross mark, the distance sensor 8 sends out a first electric signal, and the distance calculator 4 starts to work; when the distance reactor 8 returns from the recess of the cross mark to the surface of the plate 5, the vertical distance again changes, the distance sensor 8 emits a second electrical signal, and the distance calculator 4 stops working.
The distance calculator calculates the horizontal distance between the two ends of the cross mark according to the traveling speed of the pressure head (preset in working) and the interval time between the two electric signals. The processing module 6 then collects the horizontal distance, i.e. the length of the cross mark, and divides the length by 2 to obtain the center-to-end distance of the cross mark, and the processing module 6 also records the coordinates of each time the distance sensor 8 sends out an electrical signal, i.e. the coordinate positions of the two ends of the cross mark, and then calculates the coordinates of the center of the cross mark in combination with the center-to-end distance of the cross mark.
