[0028] As Figures 1 to 7 shown, a desktop drilling machine includes a desktop drilling machine main body 1. A fixed plate 2 is fixedly installed on the upper side of the desktop drilling machine main body 1. A first gear rotating rod 3 and a second gear rotating rod 4 are respectively rotatably connected to the front side of the fixed plate 2. A disc 6 is installed on the front side of the first gear rotating rod 3. A U-shaped plate 7 is fixedly connected to the front side of the disc 6. A threaded rotating rod 8 is rotatably connected inside the U-shaped plate 7. The first gear rotating rod 3 and the second gear rotating rod 4 are meshed with each other;

[0029] The outer surface of the threaded rotating rod 8 is threadedly connected with a displacement block 9. The lower side of the displacement block 9 is connected with an electric push rod 10. The lower side of the electric push rod 10 is installed with a bottom plate 14. The lower side of the bottom plate 14 is rotatably connected with a rotating seat 15. The front side of the rotating seat 15 is slidably clamped with an embedded block 17. A drill bit 18 is installed on the lower side of the embedded block 17. Through the settings of the rotating seat 15 and the drill bit 18, as the rotating seat 15 rotates, the drill bit 18 can be driven to rotate continuously for drilling work, which is convenient to use. The upper side of the rotating seat 15 penetrates through the bottom plate 14 and extends to the upper side of the bottom plate 14. The upper side of the rotating seat 15 is fixedly connected with a second servo motor 16 through a motor mounting plate.

[0030] The rear side of the second gear rotating rod 4 penetrates through the fixing plate 2 and extends to the rear side of the fixing plate 2. A first servo motor 5 is fixedly connected to the rear side of the second gear rotating rod 4 through a motor mounting plate. Two connecting plates 19 are installed on the front side of the rotating seat 15. A first positioning plate 20 is clamped inside the two connecting plates 19. A second positioning plate 21 is clamped inside the rotating seat 15. The first positioning plate 20 and the second positioning plate 21 are used to fixedly embed the embedding block 17. Second bolts 22 are threadedly connected to the front sides of the two connecting plates 19. The second bolts 22 can be used to reinforce the installation of the first positioning plate 20 and make the drill bit 18 more firmly installed.

[0031] A protective cover 12 is fixedly connected to the upper side of the bench drilling machine main body 1. An extension baffle 13 is slidably clamped on the upper side of the protective cover 12. Through the installation of the protective cover 12 and the extension baffle 13, the drilling position can be protected by the two of them to prevent debris from splashing everywhere. Two square grooves 11 are opened on the upper side of the bench drilling machine main body 1. Two card boxes 24 are clamped on the upper side of the bench drilling machine main body 1. Through the installation and use of the square grooves 11 and the card boxes 24, the drilling debris can enter the card boxes 24 along the square grooves 11 for centralized collection of debris, which is time-saving and labor-saving. The card boxes 24 are located in the square grooves 11. A first bolt 222 is threadedly connected to the front side of the bench drilling machine main body 1. The first bolt 222 is used to fix the extension baffle 13.

[0032] A rubber round pad 23 is installed on the upper side of the bench drilling machine main body 1. Through the setting of the rubber round pad 23, the rubber round pad 23 can increase the friction with the workpiece and make the workpiece stably clamped for drilling. Two support plates 25 are connected to the upper side of the bench drilling machine main body 1. A bidirectional threaded rotating shaft 26 is rotatably connected to the inner sides of the two support plates 25. Two L-shaped plates 29 are threadedly connected to the outer surface of the bidirectional threaded rotating shaft 26. Rubber blocks 30 are arrayedly connected to the inner sides of the two L-shaped plates 29.

[0033] The left side of the bidirectional threaded rotating shaft 26 penetrates through the support plate 25 and extends to the left side of the support plate 25. A third servo motor 27 is fixedly connected to the left side of the bidirectional threaded rotating shaft 26 through a motor mounting plate. Two first smooth rods 28 are connected to the inner sides of the two support plates 25. Through the setting of the two first smooth rods 28, the movement trajectories of the two L-shaped plates 29 can be restricted by the two first smooth rods 28, so that the two L-shaped plates 29 can move back and forth smoothly to clamp the workpiece to be drilled. Cleaning brushes 111 are fixedly installed on the lower sides of the two L-shaped plates 29. The cleaning brushes 111 are used to clean the drilling debris.

[0034] The second gear rotating rod 4 is located below the first gear rotating rod 3. The left side of the threaded rotating rod 8 penetrates through the U-shaped plate 7 and extends to the left side of the U-shaped plate 7. A fourth servo motor 31 is fixedly connected to the left side of the threaded rotating rod 8 through a motor mounting plate. Two second smooth rods 32 are connected inside the U-shaped plate 7. Through the arrangement of the two second smooth rods 32, the movement track of the displacement block 9 can be restricted by the two second smooth rods 32, so that the displacement block 9 can move back and forth smoothly, and thus the drilling position can be adjusted flexibly.

[0035] The working principle of a bench drilling machine provided by the present utility model is as follows:

[0036] By driving the second gear rotating rod 4 to rotate through the output shaft of the first servo motor 5, then the second gear rotating rod 4 can drive the disc 6 at the first gear rotating rod 3 to rotate. In this way, the angle of the drill bit 18 can be adjusted as the disc 6 rotates. Thus, the bench drilling machine can be flexibly adjusted to different angle drilling states for more flexible and convenient drilling operations. Then, the output shaft of the fourth servo motor 31 drives the threaded rotating rod 8 to rotate forward or backward, so that the displacement block 9 on the threaded rotating rod 8 can drive the drill bit 18 to move back and forth, so that the drilling position of the drill bit 18 can be adjusted left and right. Then, the electric push rod 10 can drive the bottom plate 14 to move up and down. At this time, the drill bit 18 at the bottom plate 14 can be flexibly adjusted in height to adapt to workpieces of different sizes, so as to flexibly adjust the drilling requirements of the bench drilling machine and improve the drilling effect when the bench drilling machine is used.

[0037] By clamping the embedding block 17 into the inside of the rotating seat 15, and then inserting the second positioning plate 21 into the inside of the rotating seat 15 and the embedding block 17. At this time, the first positioning plate 20 is clamped to the two connecting plates 19. In this way, the two positioning plates can be clamped together to fix the drill bit 18 at the embedding block 17. This clamping method makes it convenient to quickly replace different drill bits 18, saving time and effort, so as to improve the replacement efficiency of the drill bit 18. Then, the output shaft of the third servo motor 27 drives the bidirectional threaded rotating shaft 26 to rotate, so that the two L-shaped plates 29 on the bidirectional threaded rotating shaft 26 can move towards each other. At this moment, the rubber blocks 30 at the two L-shaped plates 29 can adaptively clamp workpieces of different sizes, facilitating the stable progress of the drilling work. At the same time, when the bidirectional threaded rotating shaft 26 rotates in reverse, the cleaning brushes 111 at the two L-shaped plates 29 can move relatively, so that the cleaning brushes 111 can be used to clean the drilling debris, and the drilling debris falls into the card box 24 for unified collection, avoiding the messy distribution of the drilling debris and affecting the drilling work.

[0038] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
