[0024] See also Figure 2In the embodiment of the present invention, one end of the top plate 76 away from the output shaft of the hydraulic cylinder 75 is located directly below the annular axis between the through grooves 73, and one end of the top plate 76 away from the output shaft of the hydraulic cylinder 75 is located below the drill bit 74. When the disc 72 rotates, each through groove 73 on the disc 72 will pass through the position of the top plate 76, so that the top plate 76 can push the drill bit 74 of the required size into the positioning cylinder 61.

[0025] See also Figure 3 In the embodiment of the present invention, the driving mechanism 78 includes a second servo motor 785 installed at the lower part of one end of the limit seat 4 away from the drilling motor 5. The output shaft of the second servo motor 785 is located at the upper position of the limit seat 4 and is connected to a threaded rod 786. The outside of the threaded rod 786 is screwed with an L-shaped seat 781 through a thread. The side of the L-shaped seat 781 away from the threaded rod 786 is installed with a first servo motor 782. The output shaft of the first servo motor 782 is located at the inner side of the L-shaped seat 781 and is connected to a screw rod 783. The outside of the screw rod 783 is screwed with a limit column 784 through a thread. The lower end of the limit column 784 is fixedly connected to the upper part of the support 77.

[0026] When in use, drill bits 74 of various sizes and models are placed in the corresponding through grooves 73 on the disc 72, and then the first servo motor 782 drives the screw 783 to rotate, and the screw 783 drives the limiting column 784 to move, and the limiting column 784 will drive the support 77 to move, and then the disc 72 can be driven to move, so that the arc axis between the through grooves 73 on the disc 72 is located directly below the positioning member 6, and then the hydraulic cylinder 75 drives the top plate 76 to move, and the top plate 76 pushes the drill bit 74 upward, so that the block 741 on the drill bit 74 is stuck in the positioning tube 61, and the power of the electromagnet 62 is turned on, and the electromagnet 62 will adsorb the iron plate 744. Under the elasticity of the spring 745, the iron plate 744 will move and fit with the inner wall of the positioning tube 61, and under the operation of the drilling motor 5, the positioning member 6 is driven to rotate. When the positioning groove 63 on the positioning tube 61 passes the position of the iron plate 744, the electromagnet 62 The suction force generated on the iron plate 744 will increase, so that the iron plate 744 will be adsorbed into the positioning groove 63, thereby fixing the block 741 and completing the installation of the drill bit 74. After the installation is completed, the second servo motor 785 drives the threaded rod 786 to rotate, so that the L-shaped seat 781 moves downward, and then the disc 72 moves downward, so that the through groove 73 on the disc 72 leaves the position of the drill bit 74. When disassembly is required, the power supply of the electromagnet 62 is turned off to release the adsorption work on the iron plate 744, and then under the elasticity of the spring 745, the iron plate 744 will return to the limiting groove 743 on the block 741, and then the drill bit 74 will fall from the positioning tube 61. Before disassembly, the through groove 73 on the disc 72 that is compatible with the drill bit 74 to be disassembled is located directly below the positioning tube 61, so that the drill bit 74 will fall into the corresponding through groove 73 on the disc 72, completing the disassembly work.

[0027] See also Figure 4 In the embodiment of the present invention, the drill bit 74 includes a clamping block 741, and limiting grooves 743 are provided on both sides of the clamping block 741. Iron plates 744 are slidably installed in the two limiting grooves 743. The iron plates 744 and the inner sides of the limiting grooves 743 are connected by springs 745. A drilling head 742 is screwed into the bottom of the clamping block 741 through threads.

[0028] See also Figure 5 In the embodiment of the present invention, the positioning member 6 includes a positioning cylinder 61 connected to the output shaft of the drilling motor 5, the upper part of the positioning cylinder 61 is closed, and the lower part is open, so that the block 741 can be inserted into the positioning cylinder 61 through the opening, and the outer wall of the positioning cylinder 61 is provided with an electromagnet 62, and both sides of the inner wall of the positioning cylinder 61 are provided with positioning grooves 63 adapted to the iron plate 744.

[0029] See also Figure 4-5In the embodiment of the present invention, the suction force of the electromagnet 62 on the iron plate 744 is greater than the elasticity of the spring 745, and the positioning tube 61 is made of magnetic isolation material. When the clamping block 741 is inserted into the positioning tube 61, the suction force of the electromagnet 62 on the iron plate 744 is small. When the positioning groove 63 inside the positioning tube 61 corresponds to the iron plate 744, the suction force of the electromagnet 62 on the iron plate 744 will increase, so that the iron plate 744 can be stuck in the positioning groove 63, thereby completing the installation of the drill bit 74.

[0030] See also Figure 3 In the embodiment of the present invention, a limiting shaft 787 is slidably installed through the upper part of one end of the L-shaped seat 781 close to the threaded rod 786, and the lower end of the limiting shaft 787 is fixedly connected to the upper part of the limiting seat 4. The limiting shaft 787 serves as a limiting guide for the L-shaped seat 781.

[0031] Working principle: Drill bits 74 of various sizes are placed into the corresponding through slots 73 on the disc 72, and then the first servo motor 782 drives the screw 783 to rotate, and the screw 783 drives the limit column 784 to move, and the limit column 784 will drive the support 77 to move, and then drive the disc 72 to move, so that the arc axis between the through slots 73 on the disc 72 is located directly below the positioning member 6;

[0032] Then the hydraulic cylinder 75 drives the top plate 76 to move, and the top plate 76 pushes the drill bit 74 upward, so that the block 741 on the drill bit 74 is stuck in the positioning tube 61, and at the same time, the power of the electromagnet 62 is turned on, and the electromagnet 62 will adsorb the iron plate 744. Under the elasticity of the spring 745, the iron plate 744 will move and fit with the inner wall of the positioning tube 61. Under the operation of the drilling motor 5, the positioning member 6 is driven to rotate. When the positioning groove 63 on the positioning tube 61 passes the position of the iron plate 744, the suction force generated by the electromagnet 62 on the iron plate 744 will increase, so that the iron plate 744 will be adsorbed into the positioning groove 63, thereby fixing the block 741, completing the installation of the drill bit 74. After that, the second servo motor 785 drives the threaded rod 786 to rotate, so that the L-shaped seat 781 moves downward, and then the disc 72 moves downward, so that the through groove 73 on the disc 72 leaves the position of the drill bit 74. When disassembly is required, the power supply of the electromagnet 62 is turned off to release the adsorption work on the iron plate 744, and then under the elasticity of the spring 745, the iron plate 744 will return to the limiting groove 743 on the block 741, and then the drill bit 74 will fall from the positioning cylinder 61. Before disassembly, the through groove 73 on the disc 72 that is compatible with the drill bit 74 to be disassembled is located directly below the positioning cylinder 61, so that the drill bit 74 will fall into the corresponding through groove 73 on the disc 72, and the disassembly work is completed;

[0033] After the disassembly is completed, the first servo motor 782 continues to work to allow the disc 72 to leave the bottom of the positioning member 6, and then the second servo motor 785 drives the threaded rod 786 to rotate, and the threaded rod 786 drives the L-shaped seat 781 to move, so that it moves upward, and then drives the disc 72 to move upward so that it is higher than the installed drill bit 74. Then the robotic arm 3 drives the limit seat 4 to move, and the plastic barrel that needs to be drilled is placed on the workbench 1, so that the drill bit 74 moves to the position where the hole needs to be drilled, and then the drilling motor 5 drives the positioning member 6 to rotate, and the positioning member 6 will drive the drill bit 74 to rotate, and the drill bit 74 drills the plastic barrel.
