[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A drilling component and a grinding component are set. The protective cover is driven downward by the hydraulic rod. The protective cover can drive the bidirectional motor to move downward through the support plate. The bidirectional motor can drive the drill bit to rotate at high speed to perform drilling operations on the metal plate. When the metal plate needs to be polished, the drive motor is driven downward by the electric push rod to drive the grinding disc to move to the bottom of the drill bit. Then, the drive motor can be driven downward by the hydraulic rod. The drive motor drives the grinding disc to rotate at high speed, so that the metal plate can be polished, realizing rapid switching between drilling and polishing operations, which is easy to use.

[0017] 2. A tightening component is set up. When the protective cover moves downward, the rubber pad will be pressed against the metal plate, and at the same time, multiple springs will be squeezed to shrink the telescopic cylinder. The protective cover and the telescopic cylinder work together to cover the drill bit and the grinding disc to avoid iron filings and dust, thereby improving safety. Through the action of multiple springs, the metal plate can be pressed tightly to avoid displacement during drilling and grinding operations.

[0018] 3. A dust suction component is provided. During the drilling or grinding operation, the bidirectional motor can drive the round rod to rotate. The round rod can drive the shaft rod to rotate through the first bevel gear and the second bevel gear. The shaft rod can drive the fan blades to rotate at high speed. The high-speed rotating fan blades can generate negative pressure in the rectangular tube, thereby sucking the iron filings and dust on the metal plate into the rectangular tube through the dust suction pipe. There is no need for staff to clean the metal plate, which increases practicality.

[0019] 4. A dust removal component and a transmission component are provided. The iron filings and dust sucked into the rectangular cylinder will be stopped by the dustproof net and fall on the inner bottom of the rectangular cylinder. When the hydraulic rod drives the protective cover to move upward, the protective cover can drive the piston cylinder one to move upward through the rectangular cylinder, and the piston cylinder one can drive the piston cylinder two to move upward. At this time, since the piston two is fixed by the long rod, the piston two can draw the air in the piston cylinder one into the piston cylinder two, so that a negative pressure is generated in the piston cylinder two, so that the piston one can be pulled toward the outside. The piston one can drive the rectangular frame to move in the same direction through the threaded rod and the rotating column. The rectangular frame can push the iron filings and dust in the rectangular cylinder toward the outside, and finally fall into the dust collecting box through the dust exhaust pipe, which is convenient for the staff to collect and clean the iron filings and dust, thereby increasing practicality.

[0020] 5. A threaded rod and a brush are provided. Since the threaded rod is threadedly connected to the piston cylinder, the threaded rod can rotate during the outward movement. The threaded rod can drive the two brushes to rotate through the rotating column. The two brushes can brush the dust net to sweep away the iron filings and crushed materials on the dust net, thereby avoiding clogging of the dust net and improving stability.

[0021] To sum up, the present invention can realize free switching between drilling and grinding operations, prevent iron filings from flying and dust from spreading, avoid affecting the health of workers and the operating field of vision, improve safety, and can also collect iron filings and dust to facilitate cleaning by workers, and can automatically brush the dustproof net to avoid blockage, thereby increasing practicality and stability.

[0040] The bidirectional motor 58 can drive the first bevel gear 75 to rotate through the round rod 74, and the first bevel gear 75 can drive the shaft 72 and the fan blade 73 to rotate through the second bevel gear 76, so that during the drilling and grinding process, the fan blade 73 can suck the iron filings and dust on the metal plate 13 into the rectangular cylinder 71 through the dust suction pipe 77, thereby cleaning the iron filings and dust on the metal plate 13;

[0041] The dust removal assembly 8 includes a rectangular frame 81, a dustproof net 82, a rotating column 84, two brushes 85, a threaded rod 86 and a dust exhaust pipe 87. The dust exhaust pipe 87 is fixedly arranged at the bottom of the outer end of the rectangular tube 71. A dust collecting box 88 is placed on the base 1. The dust exhaust pipe 87 extends into the dust collecting box 88. A sealing cover 89 is hingedly arranged at the bottom end of the dust exhaust pipe 87. A sealing gasket is arranged on the inner side of the sealing cover 89 to seal the pipe opening of the dust exhaust pipe 87. A torsion spring is arranged at the hinge between the sealing cover 89 and the dust exhaust pipe 87.

[0042] The torsion spring can drive the sealing cover 89 to rotate upward and reset, blocking the dust exhaust pipe 87, and the torsion spring has a light torque, which can only lift the sealing cover 89. When iron filings and dust fall on the sealing cover 89, the sealing cover 89 can be pressed down to open and fall into the dust box 88.

[0043] The rectangular frame 81 is slidably arranged against the inner wall of the rectangular tube 71, the dust-proof net 82 is fixedly arranged in the rectangular frame 81, a fixed plate 83 is fixedly arranged in the rectangular frame 81, a rotating column 84 is rotatably arranged on the inner side of the fixed plate 83, the rotating column 84 penetrates the dust-proof net 82 and is movably arranged, two brushes 85 are fixedly arranged on the rotating column 84, the two brushes 85 are arranged against the dust-proof net 82, a threaded rod 86 is fixedly arranged at the other end of the rotating column 84, and a transmission component 9 is arranged at the other end of the threaded rod 86;

[0044] The transmission assembly 9 includes a piston cylinder 91, a piston 92, a piston cylinder 93, pistons 94 and 95. The piston cylinder 91 passes through one side of the rectangular cylinder 71 and is fixedly arranged. The piston 92 is slidably arranged in the piston cylinder 91. The threaded rod 86 passes through one side of the piston cylinder 91 and is threadedly connected. One end of the threaded rod 86 is rotatably arranged on the piston 92. The piston cylinder 93 passes through the bottom outer end of the piston cylinder 91 and is fixedly arranged. The piston 94 is slidably arranged in the piston cylinder 93. The long rod 95 is fixedly arranged at the bottom of the piston 94. The long rod 95 passes through the bottom of the piston cylinder 93 and is movably arranged.

[0045] The threaded rod 86 has a larger pitch and a smaller friction force. When the piston 1 92 drives the threaded rod 86 to move, the piston cylinder 91 can squeeze the thread of the threaded rod 86 to make the threaded rod 86 rotate;

[0046] When the hydraulic rod 4 drives the protective cover 51 to move upward, the rectangular cylinder 71 can drive the piston cylinder 1 91 to move upward, and the piston cylinder 1 91 can drive the piston cylinder 2 93 to move upward. At this time, the piston 2 94 can draw the air in the piston cylinder 1 91 into the piston cylinder 2 93, thereby driving the piston 1 92 to move outward, and driving the threaded rod 86 to rotate outward, thereby driving the rectangular frame 81 to move in the same direction through the rotating column 84. The rectangular frame 81 pushes the iron filings and dust in the rectangular cylinder 71, and finally discharges them into the dust box 88 through the dust exhaust pipe 87 for collection and cleaning. At the same time, the rotating column 84 can drive the two brushes 85 to rotate, and the two brushes 85 can sweep the iron filings and dust on the dustproof net 82 to avoid clogging.

[0047] The present invention can be explained by the following operation mode:

[0048] 1. When in use, the staff first places the metal sheet 13 on the operating table 11, and then drives the protective cover 51 to move downward through the hydraulic rod 4, so that the rubber pad 56 is against the metal sheet 13, and the metal sheet 13 is tightly fixed by multiple springs 54. At the same time, the piston 2 94 can push the piston 1 92 to move inward and reset, thereby driving the dust screen 82 and the rectangular frame 81 to move inward and reset through the threaded rod 86 and the rotating column 84, and then start the bidirectional motor 58 to drive the drill bit 59 to rotate at high speed to perform a punching operation on the metal sheet 13. At the same time, the bidirectional motor 58 drives the first bevel gear 75 to rotate through the round rod 74, and the first bevel gear 75 drives the shaft rod 72 and the fan blade 73 to rotate at high speed through the second bevel gear 76. The high-speed rotating fan blade 73 discharges the air in the rectangular tube 71, so that negative pressure is generated in the rectangular tube 71, thereby sucking iron filings and dust on the metal sheet 13 into the rectangular tube 71 through the dust suction pipe 77, and the iron filings and dust are blocked by the dust screen 82;

[0049] 2. If the metal plate 13 needs to be polished, the electric push rod 61 drives the polishing disc 64 to move downward to below the drill bit 59, and then the hydraulic rod 4 drives the protective cover 51 to move downward to tightly fix the metal plate 13, and finally the driving motor 63 drives the polishing disc 64 to rotate at a high speed to perform the polishing operation on the metal plate 13. During the polishing operation, the bidirectional motor 58 can still drive the fan blades 73 to perform the dust collection operation;

[0050] 3. After a single drilling or grinding operation, the staff can drive the protective cover 51 to move upward through the hydraulic rod 4 to loosen the metal plate 13, and then switch the drilling or grinding operation, or replace the metal plate 13. At the same time, the protective cover 51 can drive the piston cylinder 1 91 and the piston cylinder 2 93 to move upward through the rectangular cylinder 71, and the piston 2 94 can pull the piston 1 92 outward, thereby driving the threaded rod 86 to rotate outward, thereby driving the rectangular frame 81 to move in the same direction through the rotating column 84, and the rectangular frame 81 can push the iron filings and dust in the rectangular cylinder 71, and the iron filings and dust can push the sealing cover 89 open, and finally be discharged into the dust box 88 for collection and cleaning;

[0051] 4. At the same time, the threaded rod 86 can drive the rotating column 84 to rotate, and the rotating column 84 can drive the two brushes 85 to rotate. The two brushes 85 can sweep the iron filings and dust on the dustproof net 82 and finally discharge them into the dust collecting box 88 to avoid clogging, and then the drilling or grinding operation can continue.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
