[0002] In existing technologies, drilling machines are typically used to drill holes in sheet metal. The drill bit on a drilling machine can usually only make one hole at a time. When a large number of holes need to be drilled on the sheet metal, such as... Figure 1 The floor heating panel K shown typically requires multiple holes 100mm to be drilled, which is time-consuming and labor-intensive using a traditional drilling machine.

While using a CNC machining center can improve processing efficiency, it greatly increases machine tool costs, reducing economic benefits. Therefore, it is necessary to design a panel drilling machine capable of drilling multiple holes simultaneously to improve processing efficiency, shorten processing time, reduce processing costs, and increase economic benefits.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] This utility model describes a board drilling machine using drilling holes in underfloor heating panels as an example. Underfloor heating panels are typically square in shape.

[0028] like Figures 2 to 6 As shown, the sheet metal punching machine of this utility model includes a frame 1, on which a conveyor belt device 5, a sheet metal limiting device, a lifting frame 3, and a lifting drive device are arranged. Multiple punching devices are mounted on the lifting frame 3. The conveyor belt device is located below the punching devices. Each punching device 2 includes a punching motor 21 and a drill bit 22 fixedly connected to the output end of the punching motor 21. The punching motor 21 is fixedly connected to the lifting frame 3. A vertical guide assembly 4 is provided between the lifting frame 3 and the frame 1. The lifting drive device drives the lifting frame 3 to move up and down along the vertical guide assembly 4. When the conveyor belt device conveys the sheet metal to the punching area below the multiple punching devices 2, the sheet metal limiting device clamps and positions the sheet metal, the punching motor 21 drives the drill bit 22 to rotate, and simultaneously the lifting drive device drives the multiple punching devices 2 to move downwards with the lifting frame 3 to complete the punching. The lifting frame 3 includes a mounting plate 31, on which the multiple punching motors 21 are fixed.

[0029] The number and position of the aforementioned drilling motors 21 and drill bits are set according to the product to be processed. The number of drilling motors 21 on the mounting plate 31 can be increased or decreased according to the number of holes to be drilled. For example, when drilling holes in two side-by-side floor heating panels, 12 holes need to be drilled in each panel. Therefore, the drilling machine in this embodiment needs to be equipped with 24 drilling devices 2 on the mounting plate 31. The position of the drilling devices 2 needs to be set according to the distribution of holes on the floor heating panels.

[0030] This utility model's board drilling machine can drill multiple holes simultaneously, resulting in high drilling efficiency and significantly reduced processing costs. It can complete the processing of underfloor heating panels in one go. If the drilling machine's specifications are increased, it can even drill holes in multiple underfloor heating panels at once, greatly improving efficiency.

[0031] like Figure 2 As shown, a cover 13 is fixed on the frame 1, and an observation window 131 is provided on the front side of the cover 13.

[0032] In some embodiments, such as Figures 3 to 6 As shown, the conveyor belt device 5 includes a belt mounting frame 51, a drive roller 52, a driven roller 53, multiple strip-shaped annular belts 54, and a belt drive motor 55. The belt mounting frame 51 is fixedly connected to the frame 1. The drive roller 52 is rotatably mounted on the upstream end of the belt mounting frame 51, and the driven roller 53 is rotatably mounted on the downstream end of the belt mounting frame 51. The multiple strip-shaped annular belts are spaced apart and evenly wound around the drive roller 52 and the driven roller 53. The belt drive motor 55 drives the drive roller 52 to rotate.

[0033] In some embodiments, such as Figure 5 and Figure 6 As shown, the plate limiting device includes a fixed baffle 61, a movable baffle mechanism, and two rotating baffle mechanisms. The fixed baffle 61 is fixedly connected to the frame 1. The movable baffle mechanism includes a movable baffle 62 and a first push-pull drive device 63. The first push-pull drive device 63 is connected to the frame 1 and the movable baffle 62 respectively. The movable baffle 62 is arranged opposite to the fixed baffle 61. The rotating baffle mechanism includes a rotatable baffle 64, a push-pull handle 65, and a second push-pull drive device 66. The rotatable baffle 64 is rotatably connected to the frame 1. The length direction of the rotatable baffle 64 is perpendicular to the conveying direction S of the conveyor belt device. One end of the push-pull handle 65 is fixedly connected to one end of the rotatable baffle 64, and the other end is hinged to the second push-pull drive device 66. The second push-pull drive device 66 is mounted on the frame 1. The second push-pull drive device 66 can drive the rotatable baffle 64 to swing. The two rotatable baffles 64, the fixed baffle 61, and the movable baffle 62 form a square positioning area. Preferably, both the first push-pull drive device 63 and the second push-pull drive device 66 are pneumatic cylinders. Of course, the first push-pull drive device 63 and the second push-pull drive device 66 can also be electric cylinders or hydraulic cylinders.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, if the conveying direction of the conveyor belt device is left to right, then the length direction of the rotatable baffle 64 is the front-to-back direction. A front bearing support 101 and a rear bearing support 102 are fixed on the frame 1. The front bearing support 101 and the rear bearing support 102 are located on the front and rear sides of the belt mounting bracket 51, respectively. The rotatable baffle 64 includes a connecting shaft part 641 and a baffle part 642. The front end of the connecting shaft part 641 is rotatably mounted on the front bearing support 101, and the rear end of the connecting shaft part 641 is rotatably mounted on the rear bearing support 102.

[0035] like Figure 3 and Figure 6 As shown, when the second push-pull drive device 66 pushes the push-pull handle 65 diagonally upward, the rotatable baffle 64 rotates around the center of the connecting shaft 641, and the baffle part 642 is in a horizontal position. The floor heating panel on the conveyor belt can enter the drilling area through the rotatable baffle 64. Then, the second push-pull drive device 66 resets and pulls the rotatable baffle 64 to rotate around the center of the connecting shaft 641, so that the baffle part 642 is in a vertical position. At this time, the baffle part 642 limits the floor heating panel. At the same time, the first push-pull drive device 63 pushes the movable baffle 62 to move towards the fixed baffle 61 to clamp and limit the floor heating panel.

[0036] In some embodiments, such as Figure 3 and Figure 5 As shown, the lifting drive device includes a lifting drive motor 7, an output shaft 8, two sprockets 9 fixed on the output shaft 8, and two transmission chains 10. Both ends of the output shaft 8 are rotatably mounted on the frame 1. Each sprocket 9 is located near the end of the output shaft 8. The lifting drive motor 7 is connected to the middle of the output shaft 8 and drives the output shaft 8 to rotate. The output shaft 8 is arranged parallel to the lifting frame 3. Each transmission chain 10 is wound around the sprocket 9, and one end is fixed to the frame 1. Specifically, a crossbeam 11 is welded and fixed to the frame 1. One end of each transmission chain 10 is welded and fixed to the crossbeam 11, and the other end is welded and fixedly connected to the lifting frame 3. The lifting drive motor 7 drives the output shaft 8 to rotate, and the two sprockets 9 at both ends of the output shaft 8 rotate accordingly. Since one end of each transmission chain 10 is fixed to the frame 1, the lifting frame 3, which is fixedly connected to the other end of the transmission chain 10, is raised or lowered.

[0037] In some embodiments, such as Figure 4 and Figure 5As shown, the vertical guide assembly 4 includes a vertical guide rod 41 and a guide sleeve 42 that slides with the vertical guide rod 41. Both ends of the vertical guide rod 41 are fixedly connected to the frame 1. Specifically, the frame 1 includes an upper support beam 103 and a lower support beam 104. The upper end of the vertical guide rod 41 is fixedly connected to the upper support beam 103, and the lower end of the vertical guide rod 41 is fixedly connected to the lower support beam 104. The guide sleeve 42 is fixedly connected to the lifting frame 3. Two vertical guide rods 41 are fixedly mounted on the frame 1 on the left side of the lifting frame 3, and two vertical guide rods 41 are fixedly mounted on the frame 1 on the right side of the lifting frame 3. The positions of the vertical guide rods 41 on the left and right sides are correspondingly arranged. The vertical guide assembly 4 provides guidance for the lifting or lowering of the lifting frame 3, preventing swaying during the lifting process, and providing travel limits. The entire travel of the lifting frame 3 includes, from top to bottom, the drill bit changing position A, the standby position B, and the lowest drilling position C. The lifting frame 3 is positioned at drill bit changing position A for easy drill bit replacement. Standby position B is the usual position of the lifting frame 3. Lowest drilling position C is the position where drilling is performed during machining.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, the panel drilling machine is equipped with a dust removal device, which includes a fan, a dust removal pipe, and a motor driving the fan. One end of the dust removal pipe 12 is connected to the fan, and the other end is located near the panel being drilled. Specifically, the dust removal pipe 12 includes a ventilation hose 121. Multiple dust removal pipe mounting holes 32 are provided on the lifting frame 3. These holes 32 are located on the mounting plate 31, avoiding the drilling motor 21. The ventilation hose 121 passes through the mounting holes 32 and is fixed to the lifting frame 3. The end of the ventilation hose 121 is close to the top of the panel being drilled. The dust, debris, and powder generated during drilling of the underfloor heating panel by the panel drilling machine can be promptly removed by the dust removal device, preventing air pollution.

[0039] In summary, the sheet metal drilling machine of this invention can drill multiple holes simultaneously, has high drilling efficiency, and can reduce processing costs.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
