[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment:

[0038] Please refer to Figure 1 -

[0039] Figure 7 , a self - positioning drilling machine for plates, including a conveyor belt 1. As Figure 1 shown, the conveyor belt 1 is driven by a belt pulley 20, and plates 2 are placed at intervals on the top.

[0040] In this embodiment, an organism 3 is further provided, which is arranged on the side of the conveyor belt 1. A lifting plate 6 is slidably mounted up and down on the front surface of the organism 3. A mounting block 8 is fixedly mounted on the lifting plate 6 and can move together with the lifting plate 6. As Figure 5 shown, a drilling machine 9 is pre-installed in the mounting plate 8, and a drill bit 10 is provided at the bottom end of the output shaft;

[0041] When the lifting plate 6 drives the mounting block 8 to move downward, the drill bit 10 can drill the plate 2. In order to prevent the drill bit 10 from damaging the conveyor belt 1, in this embodiment, the conveyor belt 1 is composed of two parallel narrow belts 21, and a partition groove 22 is formed between the two narrow belts 21. After the drill bit 10 drills through the plate 2, it passes through the partition groove 22 and will not touch the narrow belt 21.

[0042] As Figure 2 shown, a backing plate 23 is fixedly mounted at the bottom of the front surface of the organism 3 for supporting the conveyor belt 1 to prevent the conveyor belt 1 from sagging during the drilling operation. A discharge groove can also be opened at the position of the backing plate 23 corresponding to the partition groove 22 to prevent slag accumulation.

[0043] In the present invention, a pressing plate 11 is mounted below the mounting block 8 through an elastic support mechanism, and a vertical hole 12 for the drill bit 10 to pass through is formed through the pressing plate 11. As Figure 5 shown, the elastic support mechanism includes a guide rod 13, a spring 14 and an anti-disengagement plate 15. Specifically, the guide rod 13 is movably inserted into the mounting block 8. The top end of the guide rod 13 is provided with the anti-disengagement plate 15, and the bottom end is fixedly connected to the pressing plate 11. A spring 14 is also sleeved on the guide rod 13, and the spring 14 is fixedly arranged between the bottom of the mounting block 8 and the top of the pressing plate 11;

[0044] When the lifting plate 6 drives the mounting block 8 to move downward, the pressing plate 11 first contacts the plate 2 and presses the plate 2, which can effectively ensure that the plate 2 remains stable during the drilling process, avoid the problem of inaccurate manual positioning, improve the drilling accuracy and consistency, and at the same time, no other electric auxiliary equipment is required.

[0045] As Figure 5 shown, positioning blocks 16 for positioning the plate 2 are provided on both sides of the bottom of the pressing plate 11, which further improves the positioning stability. The positioning blocks 16 are preferably made of silicone.

[0046] In this embodiment, a punching rod 17 is fixedly mounted at the bottom of the mounting block 8. The bottom end of the punching rod 17 is inserted into a rod groove, and the rod groove is formed through the pressing plate 11. When the mounting block 8 moves downward, the plate 2 can also be punched through the punching rod 17, which further enriches the functions of the drilling machine and provides more processing options.

[0047] As Figure 1 andFigure 3 As shown, a drive disk 4 is rotatably mounted on the machine body 3, and a hinge shaft 5 is eccentrically and rotatably mounted on the drive disk 4. The other end of the hinge shaft 5 is rotatably connected to the lifting plate 6. When the drive disk 4 rotates, the lifting plate 6 can be driven to move up and down through the hinge shaft 5.

[0048] In order to ensure the stability of the up-and-down movement of the lifting plate 6, in the present invention, a guide rail 7 is fixedly mounted on the machine body 3. The guide rail 7 is slidably clamped in a guide groove, and the guide groove is formed in the lifting plate 6 to ensure the stable movement of the lifting plate 6 and reduce wear.

[0049] As Figure 3 shown, a sandwich layer 18 is formed in the machine body 3. A driving wheel 19 is rotatably mounted in the sandwich layer 18. Both the driving wheel 19 and the drive disk 4 are mounted on a drive shaft. The drive shaft is driven to rotate by a motor 24 fixedly mounted on the machine body 3. Thus, by controlling the operation of the motor 24, the lifting plate 6 can be moved up and down. In practical applications, the driving wheel 19 can also be connected to other mechanisms (such as a cutting dust collection system) through a synchronous belt to realize the secondary utilization of power and improve the energy utilization efficiency.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
