Align the limiting circular plate at the position where pre-punching is required, then use a screw to fix the limiting circular plate, and then pass the drill bit through the surface of the limiting circular ring to reach the punching position and perform punching.

[0004] However, when there are many punching positions on the sheet metal, it is complicated to adjust the position of the limiting circular plate using bolts, and the working efficiency is relatively low. Content of the Utility Model

A limiting plate is slidably connected to the surface of the positioning plate. Fixed blocks are fixedly connected to both side surfaces of the limiting plate. A fixing plate is inserted into the surface of the fixed block. A clamping plate is rotatably connected to the surface of the fixing plate. The clamping plate presses against the surface of the positioning plate to brake the limiting plate.

[0007] Preferably, the positioning plate is in a "C" - shaped plate structure. Scale lines are provided on the surface of the positioning plate. Screw holes are opened on both side surfaces of the positioning plate. Bolts are screwed on the surface of the screw holes. The workbench is clamped between the two bolts.

[0008] Preferably, a sliding groove is opened on the surface of the positioning plate. The sliding groove is a square groove. The limiting plate is slidably connected to the surface of the sliding groove. The limiting plate is in an annular circular plate structure.

[0009] Preferably, limiting grooves are opened on both side surfaces of the positioning plate. The limiting grooves are square grooves. The sliding groove communicates with the limiting grooves.

[0010] Preferably, the fixed block is in a cylindrical structure. The fixed block is slidably connected to the surface of the limiting groove. A block groove is opened at one end of the fixed block away from the limiting plate.

[0011] Preferably, a rubber strip is fixedly connected to the surface of the slider groove, and the rubber strip is in a stretched state.

[0012] The fixed surface of the fixing plate is fixedly connected to the other end of the rubber strip, and the fixing plate is in a cylindrical structure.

[0013] Preferably, a fixing groove is provided on the surface of one end of the fixing plate away from the rubber strip, and the fixing groove is an annular groove.

[0014] The clamping plate is rotatably connected to the surface of the fixing groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0024] Example 1

[0025] Please refer to Figure 1-Figure 2 , the present utility model provides a technical solution: a punching and positioning device for sheet metal processing, including a positioning plate 1, the positioning plate 1 is lapped on the surface of the workbench 2, a limiting plate 7 is slidably connected to the surface of the positioning plate 1, sliding blocks 8 are fixedly connected to both side surfaces of the limiting plate 7, a fixing plate 11 is inserted on the surface of the sliding block 8, a clamping plate 13 is rotatably connected to the surface of the fixing plate 11, the clamping plate 13 presses on the surface of the positioning plate 1 to brake the limiting plate 7, adjust the traditional positioning device, set a plurality of limiting circular plates in the positioning device, simultaneously realize the positioning of a plurality of punching positions, and use the clamping plate to brake the limiting circular plates, with simple operation and improved working efficiency of positioning and punching.

[0026] Example 2

[0027] Please refer to Figure 3 , on the basis of Example 1, in order to realize the sliding and fixing of the positioning plate 1, the positioning plate 1 is in a "C"-shaped plate structure, a scale line 14 is provided on the surface of the positioning plate 1, screw holes 4 are opened on both side surfaces of the positioning plate 1, bolts 3 are screwed on the surfaces of the screw holes 4, the workbench 2 is clamped between the two bolts 3, a sliding groove 5 is opened on the surface of the positioning plate 1, the sliding groove 5 is a square groove, the limiting plate 7 is slidably connected to the surface of the sliding groove 5, the limiting plate 7 is in an annular circular plate structure, limiting grooves 6 are opened on both side surfaces of the positioning plate 1, the limiting grooves 6 are square grooves, and the sliding groove 5 communicates with the limiting grooves 6.

[0028] Bolts 3 and screw holes 4 are arranged on both sides of the fixing plate 1. When the positioning plate 1 is placed on the sheet metal surface, the two bolts 3 can be used to clamp both sides of the positioning plate 3 to clamp and fix the position of the sheet metal, preventing the sheet metal from shaking and displacing during drilling.

[0029] Example 3

[0030] Please refer to Figure 4-Figure 5 , on the basis of Example 2, the sliding block 8 is in a cylindrical structure, the sliding block 8 is slidably connected to the surface of the limiting groove 6, a sliding block groove 9 is opened at one end of the sliding block 8 away from the limiting plate 7, a rubber strip 10 is fixedly connected to the surface of the sliding block groove 9, and the rubber strip 10 is in a stretched state. The other end of the rubber strip 10 is fixedly connected to the surface of the fixing plate 11. The fixing plate 11 is in a cylindrical structure, a fixing groove 12 is opened on the surface of the fixing plate 11 away from the rubber strip 10, the fixing groove 12 is an annular groove, and the clamping plate 13 is rotatably connected to the surface of the fixing groove 12.

[0031] The rubber strip 10 is provided to restrain the fixed plate 11. When the clamping plate 13 on the surface of the fixed plate 11 is pressed against the surface of the positioning plate 1, the rubber strip 10 is in a stretched state, which can prevent the clamping plate 11 from loosening and being loosely clamped. When the rotating clamping plate 11 is parallel to the horizontal plane, the rubber strip 10 drives the fixed plate 11 to rebound to the side of the limiting plate 7, and the limiting plate 7 continues to slide.

[0032] In actual use, first place the sheet metal on the surface of the workbench 2, overlap the positioning plate 1 and slide it to the appropriate position on the sheet metal surface, tighten the bolts 3 on both sides to clamp the positioning plate 1 on the surface of the workbench, and then slide multiple limit plates 7 to the position where the sheet metal needs to be drilled, pull and rotate the clamping plate 13 by hand so that the two sides of the clamping plate 13 are pressed against the surface of the positioning plate 1, and the limit plate 7 no longer moves at this time. Finally, use the punching device to punch holes in the sheet metal. When different hole positions need to be positioned, rotate the clamping plate 13, and the rubber strip 10 drives the fixed plate 11 to rebound to one side of the limit plate 7, and slide the limit plate 7 again for repositioning.
