[0028] The quick-change drilling assembly includes a housing 701, a worm gear disc 702, several drill bit holders 703, a first engagement head 704, a limiting slide groove 705, a shaft seat 706, a drive shaft 707, a square groove 708, an electric telescopic rod 709, a first drive motor 710, a second engagement head 711, a second drive motor 712, a worm gear 713, and a square rod 714. The housing 701 is fixedly mounted on the bottom of the fixed base 6. The worm gear disc 702 is rotatably connected to the inner bottom of the housing 701. The several drill bit holders 703 rotate... A worm gear disc 702 is dynamically connected to the middle part of the worm gear disc 702. A first meshing head 704 is fixedly connected to one end of the drill bit chuck 703 shaft. A limiting groove 705 is formed inside the housing 701. A shaft seat 706 is slidably connected to the inner side of the limiting groove 705. A drive shaft 707 is rotatably connected to the middle part of the shaft seat 706. A square groove 708 is formed at one end of the drive shaft 707. An electric telescopic rod 709 is fixedly installed inside the housing 701. A first drive motor 710 is fixedly installed on the top of the housing 701. A second meshing head 711 is fixedly connected to the drive shaft 702. One end of shaft 707 is fixedly mounted with a second drive motor 712 on one side of the bottom of housing 701. A worm gear 713 is rotatably connected to one side of the bottom of housing 701. A square rod 714 is fixedly mounted on one end of the output shaft of the first drive motor 710. The first meshing head 704 and the second meshing head 711 are shaped and mesh. One end of the electric telescopic rod 709 abuts against the top of the inner side of housing 701. The output end of the electric telescopic rod 709 is fixedly mounted on one side of shaft seat 706. The worm gear 713 is rotatably connected to one side of the bottom of housing 701. One end of the 13 rotating shaft is fixedly installed on one end of the output shaft of the second drive motor 712. The worm 713 meshes with the worm wheel 702. The shape of the square rod 714 matches the shape of the square groove 708. One end of the square rod 714 is slidably connected to the inside of the square groove 708. The included angle between the worm wheel 702 and the rotating shaft of the first drive motor 710 is 45-50 degrees. The included angle between the drill bit chuck 703 and the worm wheel 702 is 45-50 degrees. The central axis of the first drive motor 710 and one of the drill bit chucks 703 is on the same straight line.

[0029] The housing 701 is a two-section design, connected by bolts for easy maintenance. A limiting groove 705 is provided at the lower end of the housing 701 for the bearing seat 706 to slide up and down within the groove, allowing the drive shaft 707 to move up and down. The groove 705 and the bearing seat 706 are connected in a manner similar to a guide rail sliding connection, and are lubricated with grease. An electric telescopic rod 709 is provided, with one end mounted on the rear housing 701 and the output end mounted on the bearing seat 706. This rod is used to push and pull the bearing seat 706 up and down, enabling the drive shaft 707 to rise and fall electrically, thereby allowing the first engagement head 704 and the second engagement head 711 to engage and disengage.

[0030] It should be noted that by setting up a worm gear disk 702 and installing multiple drill bit chucks 703 on the worm gear disk 702, and setting up a first meshing head 704 and a second meshing head 711 meshing transmission method, in use, the electric telescopic rod 709 drives the shaft seat 706 to rise, so that the transmission shaft 707 drives the second meshing head 711 to rise, separating the second meshing head 704 from the first meshing head 711. At the same time, the second drive motor 712 drives the worm 713 to rotate, which drives the worm gear disk 702 to rotate, so that another drill bit chuck 703 rotates to the bottom of the transmission shaft 707. Then the electric telescopic rod 709 pushes the shaft seat 706 again, so that the second meshing head 711 and the first meshing head 704 cooperate again to complete the quick tool change, improving work efficiency.

[0033] It should be noted that a second electric lead screw guide rail 3 and a third electric lead screw guide rail 4 are set up to cooperate with the first electric lead screw guide rail 2 to form XYZ three-axis motion, which facilitates automatic position adjustment when drilling metal workpieces and further improves the drilling efficiency of the machine tool.

[0034] Working principle: When changing drill bits, the electric telescopic rod 709 drives the bearing seat 706 to rise, causing the transmission shaft 707 to drive the second meshing head 711 to rise, separating the second meshing head 704 from the first meshing head 711. At the same time, the second drive motor 712 drives the worm gear 713 to rotate, causing the worm wheel 702 to rotate, so that the other drill bit holder 703 rotates to the bottom of the transmission shaft 707. Then, the electric telescopic rod 709 pushes the bearing seat 706 again, so that the second meshing head 711 and the first meshing head 704 can cooperate again to complete the quick tool change, improving work efficiency. Meanwhile, during the drilling process, the second electric lead screw guide rail 3 and the third electric lead screw guide rail 4 cooperate with the first electric lead screw guide rail 2 to form XYZ three-axis motion, which facilitates automatic position adjustment when drilling metal workpieces, further improving the drilling efficiency of the machine tool.
