Drilling can be performed in various ways, including drilling, reaming, boring, and reaming. When drilling workpieces, the hardness, thickness, and shape of the material, as well as the size and shape of the required hole, need to be considered. In addition, appropriate cutting tools, cutting speeds, and feed rates need to be selected to ensure high-quality holes and avoid damaging the workpiece.

A platform extends from one end of the base, with symmetrically arranged limiting frames on the top of the platform. Horizontal plates extend symmetrically from both sides of the top of the platform. A first electric push rod is fixedly mounted on the top of the horizontal plates via a mounting plate, and the end of the first electric push rod is fixed to the limiting frame. A second electric push rod is mounted on one side of the top of the base.

[0029] The purging assembly 7 includes two airbags 701. Two cavities 704 are formed inside the sliding block 5. The airbags 701 are fixedly connected to the cavities 704. A sliding plate 709 is fixedly connected to one side of the airbags 701, and a sliding rod 708 is fixedly connected to one side of the sliding plate 709. The end of the sliding rod 708 away from the sliding plate 709 extends to the outside of the cavity 704 and is fixedly connected to a compression wheel 706. A return spring 707 is sleeved on the outer surface of the sliding rod 708. Both ends of the return spring 707 are fixedly connected to one side of the compression wheel 706 and one side of the sliding block 5, respectively. Sliding grooves 8 are formed on both sides of the inner wall of the support frame 2. Multiple compression blocks 705 are fixedly connected inside the sliding grooves 8. The compression blocks 705 have a trapezoidal cross-sectional shape. Both ends of the sliding blocks 5 are slidably connected to the sliding grooves 8. The compression wheel 706 is in contact with the compression blocks 705. An air outlet pipe 703 is fixedly connected to one side of the airbags 701. One end of the air outlet pipe 703... Extending to the outside of the cavity 704, an air inlet pipe 702 is fixedly connected to the other side of the airbag 701. One end of the air inlet pipe 702 extends to the outside of the cavity 704. Both the air inlet pipe 702 and the air outlet pipe 703 are equipped with one-way valves. The two air outlet pipes 703 are located on both sides of the drill bit 9. By setting up the blowing assembly 7, when the sliding block 5 drives the drill bit 9 to move downward and make the drill bit 9 drill a hole in the workpiece, the sliding block 5 drives the extrusion wheel 706 to periodically contact the extrusion block 705 through the sliding rod 708. The extrusion block 705 can reciprocate with the return spring 707. The extrusion wheel 706 drives the sliding rod 708 to reciprocate. The sliding rod 708 drives the airbag 701 to periodically contract or expand through the sliding plate 709. With the help of the air inlet pipe 702 and the air outlet pipe 703, the airflow can be delivered in one direction and the debris generated during drilling can be blown away, realizing self-cleaning during drilling of the workpiece.

[0030] The stabilizing component 3 includes two fixed plates 302. The bottom of the fixed plates 302 is fixedly connected to the top of the processing table 1. A movable lead screw 303 is rotatably connected to one side of the fixed plates 302. A lead screw seat 304 is threaded onto the outer surface of the movable lead screw 303. A clamping plate 305 is fixedly connected to the end of the lead screw seat 304 away from the movable lead screw 303. The end of the movable lead screw 303 away from the lead screw seat 304 extends to the other side of the fixed plates 302 and is fixedly connected to a knob 301. The lead screw seat 304 is away from the clamping plate. A sliding hole is provided on one side of 305, and a fixed sliding rod 306 is slidably connected in the sliding hole. One end of the fixed sliding rod 306 is fixedly connected to one side of the fixed plate 302. By setting the stabilizing component 3, the operator drives the moving lead screw 303 to rotate through the knob 301. The moving lead screw 303 drives the clamping plate 305 to move through the lead screw seat 304, so that the clamping plate 305 fits and limits the two sides of the workpiece, so that the workpiece is in a stable clamping state and avoids the workpiece from moving during processing and causing deviation in drilling.

[0031] Working principle: During use, the operator places the workpiece to be drilled on the processing table, aligning the drilling position directly below the drill bit 9. Then, the operator rotates knob 301, which drives the movable lead screw 303 to rotate. The lead screw 303 moves the lead screw seat 304, which in turn moves the clamping plate 305. This causes the clamping plate 305 to conform to and limit the workpiece on both sides, ensuring a stable clamping state. After clamping the workpiece, the operator starts the drill bit 9 and cylinder 6. Cylinder 6 moves the sliding block 5 downwards, which in turn moves the drill bit 9 downwards, causing it to drill a hole in the workpiece. In the process, the sliding block 5 drives the sliding rod 708 to move, and the sliding rod 708 drives the extrusion wheel 706 to periodically contact the extrusion block 705, so that the extrusion block 705 drives the extrusion wheel 706 to move. At the same time, the return spring 707 drives the extrusion wheel 706 to perform a return motion, so that the extrusion wheel 706 can reciprocate. The extrusion wheel 706 drives the sliding rod 708 to reciprocate, and the sliding rod 708 drives the sliding plate 709 to slide back and forth. The sliding plate 709 drives the airbag 701 to periodically contract or expand. With the help of the air inlet pipe 702 and the air outlet pipe 703, the airflow can be delivered in one direction, so that the airflow is ejected through the air outlet pipe 703 and blows away the debris generated during drilling.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
