However, the above technical solution has the problem of low applicability of the drilling device because the structure of the drilling device is large and inconvenient to move, and the plates need to be moved to the drilling table to be drilled, and it is impossible to drill the plates on-site as needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a plate drilling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A plate drilling device includes a group of support frames. A support block is fixed to the outer wall of the bottom of the support frame. An air suction hood is opened on the outer wall of the bottom of the support block. An installation block is slidably connected to the inner wall of the support frame. An air bag is fixed to the outer wall of the top of the installation block. A support plate is fixed to the outer wall of one side of the support frame. The outer wall of the top of the air bag is fixed to the outer wall of the support plate. An fixing plate is fixed to the outer wall of the support block.

[0007] As a further scheme of the utility model: A movable plate is fixed to the outer wall of one side of the installation block. A drilling machine is fixed to the outer wall of the bottom of the movable plate. The output shaft of the drilling machine is connected to a drill bit through a coupling.

[0008] As a further scheme of the utility model: A first air valve is arranged on the outer wall of one side of the installation block. The first air valve is connected to the air bag through an air pipeline. A second air valve is arranged on the outer wall of the support block. The second air valve is connected to the top of the air suction hood through an air pipeline. The first air valve and the second air valve are connected through an air pipeline.

[0009] As a further scheme of the utility model: A handle is fixed to the outer wall of the top of the movable plate.

[0010] As a further solution of the present utility model: a control switch is provided on the outer wall of the handle, and the control switch is electrically connected to the drill.

[0011] As a further solution of the present utility model: a sealing ring is fixed on the outer wall of the bottom of the support block, and a buffer block is fixed on the outer wall of the bottom of the mounting block.

[0012] As a further solution of the present utility model: a pressure relief valve is provided on the outer wall of the bottom of the mounting block, and the pressure relief valve is connected to the airbag through a pipeline.

[0013] As a further solution of the present utility model: shielding plates are respectively fixed on the outer walls of both sides of the movable plate, and a brush is provided on the outer wall of the fixed plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The staff holds the handle and places the drilling device at the position on the outer wall of the plate where drilling is required. After starting the drill, the staff pushes the movable plate as a whole downward. When the movable plate moves downward, it will drive the mounting blocks slidingly connected to the inner walls on both sides to slide downward. By pulling the airbag at the top through the mounting blocks, the airbag expands. When the airbag expands, it will pump air into the suction hood through the air pipeline between the first air valve and the second air valve, so as to form a negative pressure between the contact surface of the suction hood and the bottom plate, enabling the suction hood to adsorb on the plate, improving the stability of the whole device during drilling, enabling the downward moving drill bit to accurately drill the corresponding position of the plate, and enabling the staff to hold the drilling device to accurately and stably drill plates at different positions, improving the applicability of the drilling device.

[0016] 2. As the mounting blocks continue to move downward, the air pressure inside the airbag will gradually increase. When the air pressure inside the airbag reaches a certain value, the gas inside the airbag will push open the pressure relief valve and discharge outward, avoiding excessive air pressure inside the airbag and enabling the staff to smoothly push the movable plate as a whole to continue moving downward.

[0017] 3. The shielding plates can shield the drilling part of the plate. After drilling, the staff can sweep away the debris remaining on the plate through the brush provided on the fixed plate; the sealing ring can seal the contact surface between the suction hood and the plate surface, improving the negative pressure adsorption effect of the suction hood and the overall stability of the drilling device during drilling.

The outer wall of the top of the airbag 5 is fixed to the outer wall of the support plate 4. A fixing plate 12 is fixed to the outer wall of the support block 15; A movable plate 9 is fixed to the outer wall of one side of the installation block 6. A drilling machine 2 is fixed to the outer wall of the bottom of the movable plate 9. The output shaft of the drilling machine 2 is connected to a drill bit 11 through a coupling; A first air valve 3 is provided on the outer wall of one side of the installation block 6. The first air valve 3 is connected to the airbag 5 through an air pipeline. A second air valve 14 is provided on the outer wall of the support block 15. The second air valve 14 is connected to the top of the suction hood 19 through an air pipeline. The first air valve 3 and the second air valve 14 are connected through an air pipeline; A handle 7 is fixed to the outer wall of the top of the movable plate 9.

[0026] The staff holds the handle 7 and places the drilling device at the position on the outer wall of the plate where drilling is required. After starting the drill 2, the movable plate 9 is pushed to move downward as a whole. When the movable plate 9 moves downward, it will drive the mounting blocks 6 slidably connected to both sides on the inner wall to slide downward. The mounting blocks 6 pull the airbag 5 at the top to expand. When the airbag 5 expands, it will pump air into the suction hood 19 through the air pipeline between the first air valve 3 and the second air valve 14, so as to form a negative pressure between the contact surface of the suction hood 19 and the bottom plate, enabling the suction hood 19 to adsorb on the plate, improving the stability of the whole device during drilling, allowing the downward-moving drill bit 11 to accurately drill the corresponding position of the plate, and enabling the staff to hold the drilling device to accurately and stably drill plates at different positions, improving the applicability of the drilling device.

[0029] As Figure 2 shown, a pressure relief valve 17 is provided on the bottom outer wall of the mounting block 6, and the pressure relief valve 17 is connected to the airbag 5 through a pipeline; as the mounting block 6 continuously moves downward, the air pressure inside the airbag 5 will gradually increase. When the air pressure inside the airbag 5 reaches a certain value, the gas inside the airbag 5 will push open the pressure relief valve 17 and discharge outward, avoiding excessive air pressure inside the airbag 5 and enabling the staff to smoothly push the movable plate 9 to continuously move downward as a whole.

[0030] Working principle: The staff holds the handle 7 and places the drilling device at the position on the outer wall of the plate where drilling is required. After starting the drill 2, the movable plate 9 is pushed to move downward as a whole. When the movable plate 9 moves downward, it will drive the mounting blocks 6 slidably connected to both sides on the inner wall to slide downward. The mounting blocks 6 pull the airbag 5 at the top to expand. When the airbag 5 expands, it will pump air into the suction hood 19 through the air pipeline between the first air valve 3 and the second air valve 14, so as to form a negative pressure between the contact surface of the suction hood 19 and the bottom plate, enabling the suction hood 19 to adsorb on the plate, improving the stability of the whole device during drilling, allowing the downward-moving drill bit 11 to accurately drill the corresponding position of the plate, and enabling the staff to hold the drilling device to accurately and stably drill plates at different positions.
