Description

Technical Field

[0001] The utility model relates to the technical field related to power cabinet production equipment, in particular to a drilling device. Background Art

[0002] The existing publication number is CN108284239A, which specifically discloses a metal plate drilling device including a base, an end bearing fixedly installed on one side of the top of the base, a support column fixedly mounted in the middle of the end bearing, a rotating block fixedly mounted on the top of the support column, a sliding rod fixedly connected to the side of the rotating block, and a limited stopper fixedly connected to the end of the sliding rod away from the rotating block. The metal plate drilling device rotates on the threaded rod by the positioning nut, and cooperates with the position of the right-side benchmark and the scale to determine the deepest position of the hole. When drilling, it is only necessary to move the moving tube downward to drive the drill bit to move downward to drill until the left-side benchmark contacts the positioning nut, and then drill to the deepest position, thereby avoiding the inability to accurately control the depth of the metal plate, so that the quality of the metal plate drilling does not meet the engineering requirements, causing a waste of raw materials and reducing the processing efficiency of the metal plate.

[0003] The cabinet sheet metal parts of the power cabinet need to be drilled using drilling equipment during the production process. During the drilling process, after the hole of the workpiece is drilled through by the drill bit, there will be a certain amount of metal debris at the hole of the workpiece. Subsequently, the staff needs to clean up the metal debris at the hole, which increases the staff's operating steps, prolongs the working hours and consumes human resources, and prolongs the processing cycle. For this reason, we propose a drilling equipment. Utility Model Content

[0028] The sheet metal part is placed in the limit frame 6, and the bottom of the sheet metal part is supported on the support frame 7. The drill bit 4 is driven to rotate by the motor 3, and the first cylinder 5 drives the drill bit 4 to move downward and provide drilling force for it. The drill bit 4 can drill holes in the sheet metal part in the limit frame 6.

[0029] Since the lower end of the support frame 7 is open, the debris in the processing hole of the sheet metal part will fall under the action of gravity and pass through the support frame 7. The funnel 11 is set just below the drill bit 4, so that the funnel 11 collects and processes the debris, and then cooperates with the negative pressure mechanism to generate negative pressure airflow at the guide rod 8. The funnel 11 will also generate negative pressure airflow, so that the debris in the processing hole is efficiently and comprehensively sucked out by the suction of the airflow. Subsequently, the staff no longer needs to clean the metal debris at the punching place, which simplifies the staff's operating steps, saves working hours and human resources, and shortens the processing cycle.

[0030] Among them, two second cylinders 12 are fixedly installed on the machine base 1, and the output ends of the second cylinders 12 are fixedly connected to the support frame 7. The second cylinders 12 are arranged to drive the support frame 7 to move along the direction of the guide rod 8, and the support frame 7, the limit frame 6 and the sheet metal parts therein are synchronously translated, so that the sheet metal parts can be moved and drilling can be performed on different positions of the sheet metal parts.

[0031] The negative pressure mechanism includes a suction pump 13, which is fixedly mounted on the machine base 1.

[0032] The lower end of the conduit 10 is connected and threadedly connected to a collecting tube 16.

[0033] After drilling is completed, the suction pump 13 is shut down, and the debris at the filter screen 15 is not attracted and falls into the collection tube 16 under its own weight. The collection tube 16 can collect the debris. After the collection is completed, the collection tube 16 is rotated, and the collection tube 16 can be disassembled and the debris in the collection tube 16 can be poured out. The upper end of the sealing plug 17 is a magnet, which can absorb the metal debris in the collection tube 16 to prevent the debris from flowing back to the filter screen 15 under the action of negative pressure airflow. A built-in funnel 18 is fixedly installed at the upper end of the collection tube 16, and the built-in funnel 18 can prevent the metal debris from flowing back and rising.

By rotating the pressing block 19, the rubber anti-skid pad on the pressing block 19 is pressed on the sheet metal part in the limit frame 6, so that the sheet metal part is not easy to shake up and down during the drilling process.
