Specific implementation method

[0020] The following is combined with Figures 1-4Further detailed description of this application is provided below.

[0021] An embodiment of this application discloses a drilling device for processing polystyrene boards. Referring to Figures 1-4 , it includes a base 1, on which a workbench 11 and a vertically arranged linear guide slide 2 are installed. A drilling mechanism 3 is installed on the slide of the linear guide slide 2. The drilling mechanism 3 includes a bracket 31, a rotary joint 32, a driving motor, a connecting seat 33 and a drill bit 34. The bracket 31 is fixed on the slide of the linear guide slide 2. One end of the rotary joint 32 is fixed on the bracket 31. The rotary joint 32 is externally connected to a liquid pressure pump. The connecting seat 33 is fixed at the bottom end of the rotary joint 32. A through hole is opened in the connecting seat 33. A quick-connect fitting 35 is fixed at the position of the connecting seat 33 corresponding to the through hole. A U-shaped flow channel 341 is opened in the drill bit 34. One end of the U-shaped flow channel 341 penetrates through the drill bit 34. A quick-connect joint 36 is fixed at the position of the drill bit 34 corresponding to the U-shaped flow channel 341. A liquid outlet hole 342 communicating with the U-shaped flow channel 341 is opened on the side of the drill bit 34. A stud 37 is threadedly connected to the side of the quick-connect joint 36. A connection hole is opened at the position of the connecting seat 33 corresponding to the stud 37. A gear disk 38 is also fixed on the connecting seat 33. The driving motor is used to drive the gear disk 38 to rotate;

[0022] In order to reduce the pollution of the polystyrene board by the coolant, a collection tank 4 is also provided at the bottom of the connecting seat 33. One side of the collection tank 4 is fixed on the slide of the linear guide slide 2. A through hole 41 corresponding to the drill bit 34 is opened in the middle of the collection tank 4. In order to prevent the coolant from leaking from the position of the through hole 41, the bottom wall of the collection tank 4 is arranged in a frustum shape protruding upward. A liquid return pipe is connected to one side of the collection tank 4. The liquid outlet hole 342 on the drill bit 34 is arranged above the through hole 41.

[0023] Referring to Figure 1 and Figure 4 , the collection tank 4 is slidably connected to the slide of the linear guide slide 2, and a locking screw is connected between the collection tank 4 and the slide.

[0024] When the drill bit 34 needs to be replaced, the locking screw is unscrewed, and the collection tank 4 can be moved downward to leave space for replacing the drill bit 34.

[0025] Referring to Figure 1 , a dust suction hood 5 is also installed on the base 1. The dust suction hood 5 is externally connected to a vacuum cleaner. By providing the dust suction hood 5, a large amount of dust generated during the drilling process can be absorbed, effectively protecting the environment and reducing the impact on the health of the operator.

[0026] The implementation principle of a drilling device for processing polystyrene boards in an embodiment of this application is as follows:

[0027] The polystyrene board is laid flat on the base 1. The linear guideway slider 2 drives the drilling mechanism 3 to move downward to drill holes in it. During this process, the liquid pressure pump pumps the coolant into the rotary joint 32, and through the rotary joint 32, the connecting seat 33 and the quick connector 36, it flows into the U-shaped flow channel 341 of the drill bit 34. After flowing through the U-shaped flow channel 341, it is discharged into the collection tank 4 from the liquid outlet hole 342. When the coolant flows in the U-shaped flow channel 341, it can take away the heat on the drill bit 34, so that the drill bit 34 always maintains a low-temperature state, avoiding burning the edge of the hole and ensuring the hole-forming quality.

[0028] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, principle and application direction of this application shall be covered within the protection scope of this application.
