[0002] A drilling machine is a mechanical device that uses rotational force to make holes in substances, and is widely used in fields such as building construction, transportation, geological exploration, metallurgy, and water conservancy. Its working principle is mainly to drive the drill bit to rotate through the main shaft, supplemented by cutting fluid for cooling and lubrication to achieve drilling operations on materials. Drilling machines are divided into semi-automatic and fully automatic types. With the development of technology, fully automatic drilling machines have gradually become the development direction of enterprises. When in use, it is necessary to select appropriate drill bits, rotational speeds, and feed speeds according to the materials, pay attention to safety protection, and regularly maintain the equipment.

[0003] In the field of building construction, it is often necessary to use a drilling machine to drill holes in crossbeams or columns. During drilling, workers need to hold the drilling machine by hand. Sometimes the drilling depth is relatively deep, and workers need to hold the drilling machine for a long time. The drilling machine is relatively heavy, and workers are relatively tired during work. Moreover, a large amount of dust will be generated during the drilling process, affecting the workers' vision. Therefore, a clamping device for a building construction drilling machine is proposed. Content of the Utility Model

[0024] Please refer to again Figure 2 and Figure 3, the clamping mechanism 5 includes a clamping frame 501 fixed to the end of the drill spindle 1. A drill bit through-hole 503 is provided on one side of the clamping frame 501. A positioning threaded sleeve 505 is fixedly installed on the other side of the clamping frame 501. An adjusting screw rod 506 is provided in the positioning threaded sleeve 505. A clamping splint 502 is movably connected to the adjusting screw rod 506. A driving handwheel 504 is fixedly installed at one end of the adjusting screw rod 506. A rotating connection seat 507 is movably installed at the other end of the adjusting screw rod 506.

[0025] Specifically, the adjusting screw rod 506 can be rotated by the driving handwheel 504. After the adjusting screw rod 506 is rotated, it will drive the clamping splint 502 to move forward, so that the clamping frame 501 is clamped on the crossbeam or column, and then the drill body 3 is fixed on one side of the crossbeam or column. After the drill body 3 is fixed on one side of the crossbeam or column, drilling can be carried out. During the drilling process, there is no need for workers to hold the drill body 3 for a long time, which can greatly reduce the labor intensity of workers.

[0026] Please refer to again Figure 2 and Figure 4 , the spraying mechanism 6 includes a spray head 607 fixed in the drill bit through-hole 503 and a positioning pressure arm 603 installed on the side wall of the clamping frame 501.

[0027] Specifically, the friction wheel 606 can be driven to rotate by the drilling bit 4.

After the clamping frame 501 is clamped on the cross beam or the column, the drill rig body 3 can be started. After starting the drill rig body 3, it will drive the drilling bit 4 to rotate. During the rotation of the drilling bit 4, the drill rig handwheel 2 can be rotated to make the drilling bit 4 move forward to drill a hole in the cross beam or the column. During the drilling process, the positioning pressure arm 603 can be lowered. After lowering the positioning pressure arm 603, it will drive the friction wheel 606 to move downward, so that the friction wheel 606 contacts the drilling bit 4. During the rotation of the drilling bit 4, it will drive the friction wheel 606 to rotate. After the friction wheel 606 rotates, it will drive the movable shaft 601 to rotate. After the movable shaft 601 rotates, it will drive the drive shaft on the turbine pump 604 to rotate, thereby driving the impeller in the turbine pump 604. During the drilling process, the cooling water is sprayed onto the drilling bit 4 through the nozzle 607 to cool the drilling bit 4. And after the drilling bit 4 stops rotating, the friction wheel 606 will also stop rotating, so that the water supply is automatically stopped when the drilling bit 4 stops, reducing the waste of water resources. After the drilling is completed, the drill rig handwheel 2 can be rotated in reverse to reset the drilling bit 4.
