Description

Technical Field

[0001] This utility model belongs to the field of sheet metal machining technology, and in particular relates to a multi-hole drilling and positioning mechanism for sheet metal cabinet panels. Background Technology

[0002] Sheet metal is characterized by its light weight, high strength, electrical conductivity, low cost, and good mass production performance. It is an indispensable component in electronics and electrical appliances. As the application of sheet metal becomes more and more widespread, the design of sheet metal parts has become a very important part of the product development process.

[0003] When sheet metal machine cabinets are being produced, multiple holes need to be drilled in the cabinet panels. Often, the cabinet needs to be positioned during the drilling process. Since the thickness of each cabinet panel is different, the cabinet panels need to be fixed during drilling. Therefore, we need to design a multi-hole drilling and positioning mechanism for sheet metal machine cabinet panels. This mechanism uses a clamping structure on both sides of the top surface for positioning and clamping, which can fix the cabinet panels in the designated position with high precision. It is also suitable for fixing materials of different thicknesses. There is no need to continuously support the cabinet panels. Simply place the cabinet panels in the designated position and activate the moving and clamping structures to complete the fixing, saving clamping time. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-hole drilling and positioning mechanism for sheet metal cabinet panels, which can accurately fix the cabinet panels in designated positions and is suitable for fixing materials of different thicknesses. It does not require continuous force to support the cabinet panels; the fixing can be completed by activating the moving structure and clamping structure, thus saving clamping time and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-hole drilling and positioning mechanism for sheet metal cabinet panels includes two symmetrical support frames. A workbench is fixedly connected to the top of the two support frames. A multi-hole drilling machine is installed on the top of the rear side of the workbench. Multiple tracks are fixedly connected to the front side of the top of the workbench. A connecting plate is provided on the top of the multiple tracks. A connecting block is fixedly connected to the central axis on the rear side of the connecting plate. Cylinders are provided at the top and bottom of the workbench. The top cylinder is installed on the top of the workbench. The output end of the top cylinder is fixedly connected to the connecting block. A U-shaped block is fixedly connected to the output end of the bottom cylinder. Mounting plates are fixedly connected to the left and right sides of the top of the U-shaped block. Rotating blocks are fixedly connected to the top of the two mounting plates. Swing blocks are rotatably connected to the top of the two rotating blocks through a rotating shaft. A positioning pin is provided through the surface of the opposing side of the two swing blocks.

[0006] Preferably, each of the multiple tracks has a sliding block slidably connected to its top, and the multiple sliding blocks are fixedly connected to the connecting plate.

[0007] Preferably, a support plate is fixedly connected to the bottom of the two support frames facing each other, and the bottom cylinder is mounted on the top of the support plate.

[0008] Preferably, a rectangular frame is fixedly connected to the top of the connecting plate.

[0009] Preferably, a fixed rod is fixedly connected between each of the two support frames, and the fixed rod is slidably connected to the swing block.

[0010] Preferably, the surface of the swing block is provided with an L-shaped groove for the fixing rod to pass through, and a sheet metal cabinet plate is placed on the top of the rectangular frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model places the cabinet panel on top of a rectangular frame, and then uses the cooperation of a U-shaped block, a mounting plate, and a rotating block to make two swing blocks drive the positioning pin to fix the cabinet panel on top of the rectangular frame. Then, a multi-hole drilling machine will drill holes in the cabinet panel, which can achieve the goal of fixing the cabinet panel in a more precise position. It is suitable for fixing boards of different thicknesses, and there is no need to continuously support the cabinet panel. The fixing can be completed by activating the moving structure and the clamping structure, saving clamping time.

[0013] 2. By setting up a sliding block, this utility model ensures that the sliding block guides the connecting plate when it slides on the top of the track, so that the connecting plate will not deviate when it moves the cabinet panel to the position where the hole needs to be drilled on the surface of the cabinet panel, thus improving the stability of the connecting plate when it slides.

[0014] 3. The rectangular frame of this utility model provides a flat and stable reference surface for the cabinet panel, effectively avoiding positioning deviations and tilting caused by uneven bottom surfaces of the panel. The clamping of the positioning pins on both sides can improve the accuracy of the hole positions.

[0015] 4. By setting a fixed rod, this utility model can provide more precise guidance for the up and down movement of the swing block, ensuring that the swing block moves along the path with the L-shaped groove, avoiding deviation and shaking, and ensuring the straightness and accuracy of the movement. The fixed rod, as a bearing surface, can provide stable support for the swing block. Attached Figure Description

[0024] In the following description, embodiments of the multi-hole drilling and positioning mechanism for sheet metal cabinet panels of this utility model will be described with reference to the accompanying drawings.

[0025] Figure 1-5This invention illustrates a multi-hole drilling and positioning mechanism for sheet metal cabinet panels according to an embodiment of the present invention. It includes two symmetrical support frames 1, with a worktable 2 fixedly connected to the top of each support frame 1. A multi-hole drilling machine 3 is mounted on the top rear side of the worktable 2. Multiple tracks 4 are fixedly connected to the front side of the top of the worktable 2. Connecting plates 6 are provided on the top of the multiple tracks 4, and sliding blocks 5 are slidably connected to the top of each track 4. The sliding blocks 5 are fixedly connected to the connecting plates 6. Through the arrangement of the sliding blocks 5, when the connecting plate 6 slides on the top of the track 4, the sliding blocks 5 act as a guide for the connecting plate 6. The guiding function ensures that the connecting plate 6 moves the cabinet panel to the drilling position on the cabinet panel surface without deviation, improving the stability of the connecting plate 6 during sliding. A connecting block 8 is fixedly connected to the central axis on the rear side of the connecting plate 6, and a rectangular frame 9 is fixedly connected to the top of the connecting plate 6. The rectangular frame 9 provides a flat and stable reference surface for the cabinet panel, effectively avoiding positioning deviations and tilting caused by uneven bottom surfaces of the panel. The clamping of the positioning pins 16 on both sides can improve the accuracy of the hole positions. Cylinders 10 are installed at the top and bottom of the worktable 2. Cylinder 10 is installed on the top of workbench 2. The output end of the top cylinder 10 is fixedly connected to the connecting block 8. A U-shaped block 11 is fixedly connected to the output end of the bottom cylinder 10. Support plates 7 are fixedly connected to the bottom of the two support frames 1 on opposite sides. The bottom cylinder 10 is installed on the top of the support plate 7. Mounting plates 12 are fixedly connected to the left and right sides of the top of the U-shaped block 11. Rotating blocks 14 are fixedly connected to the top of the two mounting plates 12. Swing blocks 15 are rotatably connected to the top of the two rotating blocks 14 via a rotating shaft. A fixing rod is fixedly connected between the two support frames 1. 13. The fixed rod 13 is slidably connected to the swing block 15. The fixed rod 13 provides a more precise guide for the up and down movement of the swing block 15, ensuring that the swing block 15 moves along the path with the L-shaped groove, avoiding deviation and shaking, and ensuring the straightness and accuracy of the movement. The fixed rod 13 serves as a bearing surface and provides stable support for the swing block 15. The surfaces of the two swing blocks 15 facing each other are provided with positioning pins 16. The surface of the swing block 15 is provided with an L-shaped groove for the fixed rod 13 to pass through. The top of the rectangular frame 9 is fitted with a sheet metal cabinet plate.

[0026] Working Principle: When using this utility model, the user places the sheet metal cabinet plate on top of the rectangular frame 9, then activates the top cylinder 10. The output end of the cylinder 10 drives the connecting plate 6 to move via the connecting block 8. The connecting plate 6 then drives the sliding block 5 to slide on top of the track 4. At this point, the connecting plate 6 moves the cabinet plate at the top of the rectangular frame 9 to the position at the bottom of the multi-hole drilling machine 3 where holes need to be drilled. The top cylinder 10 is then closed, completing the movement of the cabinet plate at the top of the rectangular frame 9. The bottom cylinder 10 is then activated, and its output end drives the U-shaped block 11 upwards. The movement causes the U-shaped block 11 to move the two mounting plates 12 upwards, which in turn causes the rotating block 14 to move upwards. This causes the two rotating blocks 14 to move the swing block 15 upwards via the rotating shaft. At the same time, the two swing blocks 15 slide on the surface of the fixed rod 13. The fixed rod 13 serves as a bearing surface, providing stable support for the swing blocks 15. This causes the two swing blocks 15 to drive the positioning pin 16 to press and fix the sheet metal cabinet panel at the top of the rectangular frame 9. At this time, the sheet metal cabinet panel at the top of the rectangular frame 9 is in a stable state. Finally, the multi-hole drilling machine 3 drills holes in the sheet metal cabinet panel at the top of the rectangular frame 9.

[0027] In summary, this multi-hole drilling and positioning mechanism for sheet metal cabinets, by placing the cabinet panel on top of the rectangular frame 9, and then using the cooperation of the U-shaped block 11, the mounting plate 12, and the rotating block 14, causes the two swing blocks 15 to drive the positioning pins 16 to fix the cabinet panel at the top of the rectangular frame 9. Subsequently, the multi-hole drilling machine 3 will drill holes in the cabinet panel, thus achieving the goal of fixing the cabinet panel in a relatively accurate position. Moreover, it is suitable for fixing materials of different thicknesses, and does not require continuous force to support the cabinet panel. Fixing can be completed by activating the moving structure and clamping structure, saving clamping time.
