The circular saw has a water inlet pipe fixed to the left side of the guard, with the opening of the water inlet pipe aligned with the cutting position of the circular saw. The right side of the guard has a lower cavity, and a baffle plate is provided on the guard to close the lower cavity. The baffle plate is an arc-shaped plate, and several filters are fixed on the baffle plate. The upper cavity is located above the lower cavity in the guard. The top of the upper cavity has several air vents, and several connecting pipes are fixed between the upper cavity and the lower cavity. One end of the connecting pipe is fixed to the bottom of the upper cavity, and the other end of the connecting pipe is fixed to the bottom of the lower cavity. The right side of the guard also has an air inlet pipe. A connecting mechanism is provided between the guard and the air inlet pipe to connect the connecting pipe and the air inlet pipe.

[0006] Furthermore, the fixing mechanism includes a positioning frame. Two symmetrically arranged positioning frames are fixedly connected to the left and right sides of the rear upper surface of the sliding platform. The positioning frames are set at right angles, and the lower part of the positioning frame is hollow. The positioning frame is provided with a pressing block that can slide and reset vertically. Several fixing screws are also threadedly connected to the positioning frame. The lower end of the fixing screw is connected to the upper surface of the pressing block.

[0007] Furthermore, an anti-slip pad is fixed to the lower end of the pressing block.

[0008] Furthermore, an arc tube is connected to the bottom of the upper cavity. The arc tube is located inside the protective cover and above the circular saw. Several water outlets are also provided below the arc tube, and the outlet positions are located on the inner wall above the protective cover.

[0009] Furthermore, the connecting mechanism includes a rotating body, an installation block is fixedly connected to the outer wall of the right side of the cover, the rotating body is rotatably connected inside the installation block, and a connecting cavity is also provided in the installation block on the side of the rotating body. The end of the air intake pipe is fixedly connected to the installation block, and the air intake pipe is connected to the connecting cavity. Several inclined pipes are provided inside the rotating body, and an upper opening is provided on the connecting pipe. When the inclined pipe is in an upward inclined state, it is connected to the upper opening.

[0010] Furthermore, two symmetrical positioning grooves are provided on the circumferential side of the rotating body, and a slidable and resetting positioning block is provided in the mounting block. The positioning grooves are correspondingly set with the positioning blocks. The connecting pipe is provided with a lower through-hole corresponding to the opening of the inclined pipe.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention provides a mechanically automated plate drilling and cutting device. An airflow is formed from bottom to top in the connecting pipe through the air inlet pipe, and a negative pressure is formed at the lower opening of the connecting pipe. The filter screen then attracts the debris and dust generated by cutting the plate inside the protective cover to the baffle. At the same time, the rotation of the circular saw drives some droplets to the baffle position, so that the adsorbed flying debris and droplets combine, thereby reducing the generation of dust and avoiding the impact on the health of the workers.

[0015] 2. This invention provides a mechanically automated plate drilling and cutting device. The circular saw throws the liquid droplets onto the baffle, and some of the liquid metal enters the lower cavity. Then, it is carried into the upper cavity through the air inlet pipe. Then, the air pressure forces the liquid into the arc tube and sprays it out from several outlets to come into contact with most of the flying dust in the protective cover, thereby better removing flying debris.

[0016] 3. This invention provides a mechanically automated sheet metal drilling and cutting device. By setting up a cutting mechanism and a drilling mechanism to work together, the sheet metal can be drilled and cut on the same machine, which enhances the versatility of sheet metal processing.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, a mechanically automated sheet metal drilling and cutting device includes a main body 1. A sliding table 2 is slidably connected to the table surface of the main body 1, meaning the sliding table 2 can move left and right on the table surface of the main body 1. The sliding table 2 can be driven to move by a motor and a lead screw. This driving method is common knowledge, and the specific linkage structure is not described in detail. A fixing mechanism 7 is provided on the surface of the sliding table 2, which is used to fix the sheet metal. A top frame 3 is fixedly connected to the top of the main body 1. The top frame 3 is located above the table surface of the main body 1, and a cutting mechanism and a drilling mechanism are respectively provided at the lower end of the top frame 3. The cutting mechanism is used to cut the sheet metal, and the drilling mechanism is used to drill holes in the sheet metal. The sliding table 2 is provided with a groove 15 corresponding to the cutting mechanism.

[0026] Among them, such as Figures 1 to 3 As shown, the fixing mechanism 7 includes positioning frames 11. Two symmetrically arranged positioning frames 11 are fixedly connected to the left and right sides of the rear of the upper surface of the sliding table 2. The positioning frames 11 are set at right angles, and the lower part of the positioning frame 11 is hollow. The two corners of the board to be cut are positioned by the positioning frames 11 on the left and right sides. Specifically, the positioning frames 11 are detachably fixed to the sliding table 2. By changing the position of the positioning frames 11, the board can be positioned in different positions, and thus the board can be cut at different positions. The positioning frames 11 are also provided with a pressing mechanism that can slide vertically and return to its original position. Specifically, a reset spring can be provided between the pressing block 12 and the positioning frame 11 to realize its sliding reset function; the positioning frame 11 is also threaded with several fixing screws 14, which pass through the positioning frame 11 and the lower end of the fixing screws 14 is in contact with the upper surface of the pressing block 12. By rotating the fixing screws 14, the pressing block 12 is driven to move downward, thereby realizing the pressing and fixing of the plate; preferably, the lower end of the pressing block 12 is fixed with an anti-slip pad 13, which is used to buffer the pressing block 12 to fix the plate and prevent damage to the plate.

[0027] Among them, such as Figures 4 to 6As shown, the cutting mechanism includes a fixed frame 4. The fixed frame 4 is fixedly installed at the lower end of the top frame 3. A protective cover 5 is fixedly connected to the lower end of the fixed frame 4. The protective cover 5 is hollow and has an opening at the bottom. A circular saw 6 is rotatably connected to the protective cover 5. The circular saw 6 is used to cut the board. Specifically, a drive motor can be fixedly connected to the rear side of the protective cover 5 to drive the circular saw 6 to rotate. A water inlet pipe 16 is fixedly connected to the left side of the protective cover 5. One end of the water inlet pipe 16 is connected to a water pump, and the other end passes through the protective cover 5 and extends into it. The opening of the water inlet pipe 16 is aligned with the position where the circular saw 6 cuts the board. By setting up the water inlet pipe 16 to dissipate heat from the circular saw 6, the heat loss during the cutting process of the circular saw 6 can be prevented. The heating element is overheated, and water sprayed through the water inlet pipe 16 can absorb some of the dust at the cutting position, thus preventing a large amount of dust from flying around. A lower cavity 34 is also provided on the right side of the protective cover 5, and a baffle 17 is provided on the protective cover 5 to close the lower cavity 34. The baffle 17 can be set as an arc-shaped plate, and several filters 18 are fixedly connected to the baffle 17. An upper cavity 23 is provided above the lower cavity 34 in the protective cover 5. Several air vents 24 are provided at the top of the upper cavity 23, and several connecting pipes 19 are fixedly connected between the upper cavity 23 and the lower cavity 34. One end of the connecting pipe 19 is fixedly connected to the bottom of the upper cavity 23, and the other end of the connecting pipe 19 is fixedly connected to the lower cavity 34. At the bottom of cavity 34, on the right side of the protective cover 5, there is also an air inlet pipe 22. One end of the air inlet pipe 22 is fixed to the air pump, and the other end is fixed to the connecting mechanism. The connecting mechanism is fixed to the outside of the protective cover 5 and is used to connect the air inlet pipe 22 with several connecting pipes 19. Specifically, the connecting mechanism can form an upward airflow in the connecting pipes 19, thereby creating a negative pressure at the opening below the connecting pipes 19. When it is necessary to cut the board, the sliding table 2 is driven to move to the right, and the circular saw 6 is driven to rotate. During the movement of the sliding table 2 to the right, the board comes into contact with the circular saw 6, thereby cutting the board. During the cutting process, the circular saw 6 moves within the groove 15 of the sliding table 2, while the lower end of the protective cover 5 is a certain distance from the board. During the cutting process, water is sprayed onto the cutting location through the water inlet pipe 16. The rotation of the circular saw 6 causes some water mixed with board debris to be carried and thrown onto the baffle 17. Simultaneously, a negative pressure is created below the connecting pipe 19, which in turn creates a negative pressure within the lower cavity 34. This allows air to be drawn into the protective cover 5 through the filter screen 18, thus adsorbing some of the flying dust and debris onto the baffle 17. The droplets thrown by the circular saw 6 can then mix with the dust and debris, effectively removing some of the flying dust.

[0028] Preferred, such as Figures 4 to 5As shown, the bottom of the upper cavity 23 is also connected to an arc tube 25, which is located inside the protective cover 5 and above the circular saw 6. Several water outlets 26 are also provided below the arc tube 25, and the outlets of the water outlets 26 are located on the inner wall above the protective cover 5. During the rotation of the circular saw 6, the water is thrown onto the baffle 17, and the lower cavity 34 is in a negative pressure state, which facilitates the filtration of most of the debris in the water before it enters the lower cavity 34. At the lower end of the connecting pipe 19, the water is absorbed into the connecting pipe 19 and then lifted into the upper cavity 23. The airflow in the air inlet pipe 22 enters the upper cavity 23 to form a high air pressure. Part of the air flows out from the air outlet 24, and the other part pushes the water in the upper cavity 23 into the arc tube 25. Finally, the water is sprayed out from the water outlet 26, which can perform secondary adsorption and dust removal on the dust and debris flying inside the protective cover 5, making the dust and debris removal effect better.

[0029] Among them, such as Figures 4 to 6 As shown, the connecting mechanism includes a rotating body 29. A mounting block 27 is fixedly connected to the outer wall of the right side of the protective cover 5. The rotating body 29 is rotatably connected inside the mounting block 27. A connecting cavity 28 is also provided inside the mounting block 27 on the side of the rotating body 29. The end of the air inlet pipe 22 is fixedly connected to the mounting block 27, and the air inlet pipe 22 is connected to the connecting cavity 28. Several inclined pipes 30 are provided inside the rotating body 29. The inclined pipes 30 are correspondingly arranged with the connecting pipe 19. Specifically, the connecting pipe 19 is provided with an upper opening 191 corresponding to the inclined pipe 30. One end of the inclined pipe 30 is connected to the upper opening 191, and the other end is connected to the connecting cavity 28. At this time, the inclined pipe 30 is arranged obliquely upward. Airflow is blown in through the air inlet pipe 22. After passing through the connecting cavity 28, the airflow is dispersed into several inclined pipes 30. Finally, it forms an upward airflow in the connecting pipe 19 through the upper opening 191.

[0030] Among them, such as Figure 5As shown, the rotating body 29 has two symmetrical positioning grooves 31 on its circumferential side. The mounting block 27 has a slidable, repositionable positioning block 32. The positioning grooves 31 and 32 are correspondingly arranged, with the positioning grooves 31 being semi-cylindrical grooves 15. The contact area between the positioning block 32 and the positioning groove 31 is a correspondingly arranged semi-cylindrical protrusion. The connecting pipe 19 has a lower opening 192 corresponding to the opening of the inclined pipe 30. Through the cooperation of the positioning block 32 and the positioning grooves 31, the rotating body 29 can be easily and accurately rotated 180 degrees. After rotating 29 180 degrees, the inclined tube 30 in 29 becomes inclined downward. At this time, the opening of the inclined tube 30 is connected to the lower port 192, so that airflow can be blown out from below the connecting tube 19. The lower end of the connecting tube 19 is set to a horizontal state, so that the airflow blown out from the lower end of the connecting tube 19 is a horizontal airflow. The upper end of the baffle 17 is hinged to the protective cover 5, and the lower end is fixed with an iron component 21. The iron component 21 can be made of stainless steel or covered with a stainless steel coating on the outside. The protective cover 5 has a permanent magnet 20 fixed to it, corresponding to the iron component 21. In the initial state, the permanent magnet 20 attracts the iron component 21, thereby closing the lower cavity 34 with the baffle 17. When water is absorbed into the lower cavity 34, although some debris is filtered by the filter screen 18, some dust and debris still enter the lower cavity 34 and form deposits on the bottom wall of the lower cavity 34. The circular saw 6 can be driven by the drive motor to rotate, thereby driving clean water to be splashed onto the baffle 17 to clean the filter screen 18. Some clean water seeps into the lower cavity 34 through the filter screen 18. By changing the inclined tube 30 to a downward angle, initially, a small airflow blows bubbles out at the lower end of the connecting pipe 19. The bubbles disturb and agitate the clean water to clean the bottom part of the lower cavity 34 more thoroughly. Then, the circular saw 6 stops rotating. At this time, the airflow is increased. The baffle 17 is subjected to wind force, causing the permanent magnet 20 below to separate from the iron component 21, thereby driving the baffle 17 to rotate. At this time, the sewage can be discharged through the opening below the baffle 17.

[0031] Preferred, such as Figure 5 As shown, a sealing gasket 33 is fixedly connected to the rotating body 29. The sealing gasket 33 is located between the connecting pipe 19 and the rotating body 29. The sealing gasket 33 seals the connection between the inclined pipe 30 and the upper port 191 or the lower port 192. When the inclined pipe 30 is connected to the upper port 191, the sealing gasket 33 blocks the lower port 192. When the inclined pipe 30 is connected to the lower port 192, the sealing gasket 33 blocks the upper port 191.

[0032] Among them, such as Figure 1As shown, the drilling mechanism includes an electric drill 10. A Y-axis mechanism 8 is fixedly connected in the top frame 3. The Y-axis mechanism 8 includes components such as a slide rail, a lead screw, a drive motor, and a sliding frame. The sliding frame is slidably connected to the slide rail. The Y-axis mechanism 8 drives the sliding frame inside to move back and forth. A Z-axis mechanism 9 is provided on the Y-axis mechanism 8. The Z-axis mechanism 9 also includes components such as a slide rail, a lead screw, a drive motor, and a sliding frame. The Z-axis mechanism 9 drives the sliding frame inside to move up and down. The electric drill 10 is fixedly installed on the Z-axis mechanism 9. That is, the electric drill 10 is fixedly connected to the sliding frame in the Z-axis mechanism 9. The Z-axis mechanism 9 drives the electric drill 10 to move up and down, and the Y-axis mechanism 8 drives the electric drill 10 to move back and forth. The Y-axis mechanism 8 and the Z-axis mechanism 9 are both conventional technologies in this field. By using the Y-axis mechanism 8 and the Z-axis mechanism 9 in conjunction with the left and right movement of the sliding table 2, the electric drill 10 can be used to drill holes in different parts of the plate.
