Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a plate punching and positioning tool for steel structures. Background Art

[0002] Steel structure is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. During the processing and production of steel structures, it is necessary to use a steel plate punching device to punch holes in the steel plates so that the steel plates can be assembled and connected using screws and nuts.

[0003] In the related art, for square steel plates, commonly used punching machines generally use manual placement of steel plates when punching. A right-angle positioning plate is set on the punching machine. The square steel plate is aligned with the corners of the right-angle positioning plate to achieve precise punching. Square steel plates are generally punched at four corners. Each steel plate needs to be placed four times by the staff to complete the punching. The punching process needs to be repeated four times. The efficiency of steel plate punching is limited by the staff's operation. During the multiple placement and adjustment of the steel plate, the punching machine may be in an idle state for a longer period of time, which reduces the utilization rate of the punching machine.

[0024] A control disk 19 is rotatably connected to the center of the lower surface of the placement disk 11. Four pull rods 20 are rotatably connected to the surface of the control disk 19. The other ends of the pull rods 20 are rotatably connected to the corresponding slide bars 16. The control disk 19 drives the four slide bars 16 to slide synchronously through the pull rods 20, which is convenient for adjusting the position of the slide bar 16. The slide bar 16 is prevented from moving by turning the adjustment bolt 21, and the position of the slide bar 16 can be adjusted.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the output shaft 10 is hollow, and a nitrogen spring 13 is installed inside the output shaft 10. An adapter seat 14 is inserted in the output shaft 10, and the adapter seat 14 is plugged into the placement plate 11. When the nitrogen spring 13 pushes the adapter seat 14, the plate 23 moves up. When the servo motor 9 controls the plate slot to rotate, it ensures that the plate 23 will not be blocked by the punching seat 24. When punching the plate 23, the nitrogen spring 13 is compressed, so that the plate 23 is supported by the punching seat 24, and the punching accuracy is high.

[0026] In this embodiment, if Figure 2 and Figure 4 As shown, four pins 15 are provided at the upper end of the adapter seat 14, and four sockets 17 are provided on the lower surface of the placement plate 11.

[0032] Specifically, when in use, place the square plate 23 on the placement tray 11, as shown in FIG. Figure 5 As shown, the four blocks 12 clamp the plate 23, but the plate 23 does not move. The servo motor 9 drives the output shaft 10 to rotate through the reducer 22. The output shaft 10 drives the placement plate 11 to rotate through the adapter seat 14. The placement plate 11 drives the plate 23 to rotate through the four blocks 12, so that the corner of the plate 23 moves to the top of the punching seat 24. At this time, the servo motor 9 stops running. At this time, the punching machine punches the plate 23. After the punching is completed, the servo motor 9 controls the next corner of the plate 23 to move to the top of the punching seat 24, so as to realize the automatic adjustment of the plate 23 and improve the punching efficiency of the plate 23.
