[0005] To achieve the aforementioned objectives, the technical solution adopted by this invention is as follows: It includes a U-shaped mounting body, a data docking sleeve, a hollow data docking shaft, and a tool head assembly. A top plate is fixed to the top of the mounting body, and a through hole is provided on the top plate. The data docking sleeve is fixed inside the through hole, and the data docking shaft and the tool head assembly are fixedly connected by a clamping sleeve. A pneumatic chuck is provided inside the mounting body, and the data docking sleeve is positioned above the pneumatic chuck. The lower end of the pneumatic chuck is used to clamp the data docking shaft. Two tool head mounting rails for mounting the tool head assembly are provided at the bottom of the mounting body, and a tool slider that cooperates with the tool head mounting rails is provided on the tool head assembly.

[0007] Furthermore, the upper connector is provided with an upper slot for installing the upper data exchange spring contact; the lower connector is provided with a lower slot for installing the lower data exchange spring contact.

[0008] Furthermore, when the pneumatic chuck clamps the data docking sleeve shaft, the upper data exchange spring contact of the data docking sleeve is connected to the lower data exchange spring contact of the data docking sleeve shaft, and the upper feeding channel is connected to the lower feeding channel.

[0009] Furthermore, an extrusion motor is installed on the top plate, and the upper end of the data docking sleeve is connected to the output end of the extrusion motor through a pipe.

[0010] Furthermore, an X-axis drive nut and an X-axis guide slider are fixed to the back side of the mounting body.

[0011] Furthermore, an upper limit block is fixed to the top of each tool head mounting rail.

[0012] Furthermore, the tool head assembly is a 3D printing assembly, which includes a box-shaped printing body and a printing nozzle. The printing nozzle is located at the bottom of the printing body, and the printing body has an opening that mates with the printing nozzle. The printing body is fixedly connected to the clamping sleeve, and two tool sliders are fixed on both sides of the printing body.

[0013] Furthermore, the tool head assembly is a laser micro-engraving assembly, which includes two mounting blocks and a laser tool head. The two mounting blocks are fixedly connected to the clamping sleeve to form a U-shaped clamping opening.

Two tool sliders are fixed to both sides of the first mounting body.

[0015] The beneficial effects of this utility model are as follows:

[0016] The installation body of this utility model is equipped with a pneumatic chuck. The pneumatic chuck is used to clamp and fix the data docking sleeve shaft after it is docked with the data docking sleeve shaft. After the data docking sleeve is docked with the data docking sleeve shaft, the upper data exchange spring contact and the lower data exchange spring contact are connected to conduct, realizing data transmission of the tool head assembly.

[0047] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0048] like Figure 1 and 2 As shown, the quick-release tool head includes a U-shaped mounting body 1, a data docking sleeve 5, a hollow data docking shaft 6, and a tool head assembly 8. A top plate 2 is fixed to the top of the mounting body 1, and a through hole is provided on the top plate 2. The data docking sleeve 5 is fixed inside the through hole. The data docking shaft 6 and the tool head assembly 8 are fixedly connected by a clamping sleeve 7. The clamping sleeve 7 has an opening, and locking screws are threaded onto both sides of the opening. The data docking shaft 6 is clamped and fixed by adjusting the locking screws. An extrusion motor 3 is mounted on the top plate 2. The upper end of the data docking sleeve 5 is connected to the output end of the extrusion motor 3 via a pipe. The extrusion motor 3 is used for feeding material into the 3D printed assembly 81. An X-axis drive nut 11 and an X-axis guide slider 12 are fixed to the back side of the mounting body 1, facilitating connection between the mounting body 1 and the X-axis movement mechanism of a three-axis mobile device. Each tool head mounting slide rail 13 has an upper limit block 14 fixed at its top. The upper limit block 14 is used to limit the 3D printing component 81, the laser micro-carving component 82, and the CNC carving component 83, so as to facilitate the use of the pneumatic chuck 4 to clamp the data docking sleeve 6.

[0049] A pneumatic chuck 4 is installed inside the mounting body 1, and a data docking sleeve 5 is positioned above the pneumatic chuck 4. The lower end of the pneumatic chuck 4 is used to clamp the data docking sleeve shaft 6. Two tool head mounting rails 13 are provided at the bottom of the mounting body 1 for mounting the tool head assembly 8. The tool head assembly 8 is equipped with a tool slider 9 that mates with the tool head mounting rails 13. The tool head mounting rails 13 and the tool slider 9 work together to provide a certain degree of limitation and facilitate the installation and replacement of the tool head assembly 8.

[0050] like Figure 3 , 4 As shown in Figures 5, 6, and 7, the data docking sleeve 5 has an upper connector 51 at its bottom, which includes an upper feeding channel 52 and an upper data exchange spring contact 53. The data docking sleeve shaft 6 has a lower connector 61 at its top, which has an upper slot 54 for mounting the upper data exchange spring contact 53. A flange 55 is provided on the outside of the data docking sleeve 5, which is used to fix the data docking sleeve 5 to the top plate 2, facilitating the installation of the data docking sleeve 5.

[0051] like Figure 8 , 9 As shown in Figures 10, 11, and 12, the lower connector 61 is provided with a lower feeding channel 62 that mates with the upper feeding channel 52 and a lower data exchange spring contact 63 that mates with the upper data exchange spring contact 53. The lower connector 61 is also provided with a lower slot 64 for mounting the lower data exchange spring contact 63. The upper connector 51 and the lower connector 61 have the same structure. The upper data exchange spring contact 53 and the lower data exchange spring contact 63 are either spring-loaded male or spring-loaded female contacts. In this embodiment, both the upper data exchange spring contact 53 and the lower data exchange spring contact 63 are provided in four rows and five columns, totaling 20 contacts, for data connection and transmission.

[0052] When the top of the tool slider 9 outside the tool head assembly 8 contacts the upper limit block 14, the pneumatic chuck 4 clamps the data docking sleeve shaft 6. At this time, the upper data exchange spring contact 53 of the data docking sleeve 5 and the lower data exchange spring contact 63 of the data docking sleeve shaft 6 are connected and conductive to realize data transmission. The upper feeding channel 52 and the lower feeding channel 62 are connected to realize the feeding of 3D printing.

[0053] like Figure 13 and 14 As shown, the tool head assembly 8 is a CNC engraving assembly 83, which includes a first mounting body 831 and a CNC engraving tool head 832. The top of the first mounting body 831 is fixedly connected to the clamping sleeve 7, and the bottom of the first mounting body 831 is fixedly connected to the CNC engraving tool head 832. Two tool sliders 9 are fixed on both sides of the first mounting body 831. Since the CNC engraving tool head 832 does not require material feeding, the lower feeding channel 62 of the lower connector 61 in the data docking sleeve shaft 6 can be removed. During operation, the X-axis of the three-axis mobile device drives the mounting body 1 to move, thereby driving the CNC engraving assembly 83 to perform CNC engraving operations. The CNC engraving tool head 832 can use the spindle motor of a KOC5160 engraving machine, in conjunction with an engraving drill bit, to achieve engraving operations.

[0054] like Figure 15 and 16As shown, the tool head assembly 8 is a laser micro-engraving assembly 82. The laser micro-engraving assembly 82 includes two mounting blocks 821 and a laser tool head 822. The two mounting blocks 821 are fixedly connected to the clamping sleeve 7 to form a U-shaped clamping opening. The laser tool head 822 is fixed inside the U-shaped clamping opening, and two tool sliders 9 are fixed on both sides of the mounting blocks 821 respectively. Since the laser micro-engraving assembly 82 does not require material feeding, the lower feeding channel 62 of the lower connector 61 in the data docking sleeve shaft 6 can be removed. During operation, the X-axis of the three-axis mobile device drives the mounting body 1 to move, thereby driving the laser micro-engraving assembly 82 to perform laser micro-engraving operations. The laser tool head 822 can be a 2W-1064nm laser engraving head from Hangzhou Yiquan Optoelectronics Co., Ltd.

[0055] like Figure 17 , 18 As shown in Figure 20, the tool head assembly 8 is a 3D printing assembly 81. The 3D printing assembly 81 includes a box-shaped printing body 811 and a printing nozzle 812. The printing nozzle 812 is located at the bottom of the printing body 811. The printing body 811 has an opening that mates with the printing nozzle 812. The printing body 811 is fixedly connected to the clamping sleeve 7, and two tool sliders 9 are fixed on both sides of the printing body 811. During operation, the X-axis of the three-axis mobile device drives the mounting body 1 to move, thereby driving the 3D printing assembly 81 to perform 3D printing operations. When the data docking sleeve 5 docks with the data docking sleeve shaft 6, the data docking sleeve shaft 6 is clamped and locked by the pneumatic chuck 4. The upper feeding channel 52 is connected to the lower feeding channel 62 to realize the printing material supply for the 3D printing assembly 81. The printing nozzle 812 can use 0.4mm brass nozzles from Creality 3D printer accessories.

[0056] like Figure 19As shown, the tool head that can be quickly disassembled and replaced is used in conjunction with a three-axis mobile printing device. For example, in this embodiment, the tool head that can be quickly disassembled and replaced includes a printer body 10 with a cubic frame structure. The printer body 10 is provided with a vertically lifting platform 101. The lifting platform 101 is controlled to lift at its four corners by four Z-axis ball screws 102. Nuts that cooperate with the Z-axis ball screws 10 are fixed on the lifting platform 101. The Z-axis ball screws 102 are connected to the output end of the Z-axis stepper motor. Four Z-axis optical axes 103 are also evenly distributed on the sides of the lifting platform 101. Guide holes that cooperate with the Z-axis optical axes 103 are provided on the lifting platform 101. Two parallel Y-axis ball screws 104 are provided on the top of the printer body 10. Each Y-axis ball screw 104 is fixed to the printer body 10 by two Y-axis ball screw fixing brackets 105. The Y-axis ball screw 104 is rotatably connected to the Y-axis ball screw fixing bracket 105. The Y-axis ball screw fixing bracket 105 is provided with a sliding bearing for mounting the Y-axis ball screw 104. A slidable X-axis slider 108 is provided on the two Y-axis ball screws 104. Two Y-axis sliders 107 are provided at the bottom of the X-axis sliders 108. A Y-axis slide rail that mates with the Y-axis sliders 107 is provided on the top of the printer body 10. The X-axis slider 108 is equipped with an X-axis ball screw 110 that engages with the X-axis drive screw 11, and an X-axis slide rail 111 that engages with the X-axis guide slider 12. The X-axis ball screw 110 is mounted on the X-axis slider 108 through two X-axis ball screw mounting seats 109, and the X-axis ball screw 110 is rotatably connected to the X-axis ball screw mounting seats 109. One end of the X-axis ball screw 110 is connected to the X-axis stepper motor 112. By controlling the X-axis ball screw 110 and the Y-axis ball screw 104, the X-axis and Y-axis movements of the mounting body 1 can be realized. The Z-axis movement is realized by controlling the lifting platform 101 through the Z-axis ball screw 102, thereby enabling 3D printing, laser micro-engraving, and CNC engraving.

[0057] Working process and principle: The 3D printing component 81, laser micro-engraving component 82, and CNC engraving component 83 all have the same data docking sleeve 6. After the data docking sleeve 6 docks with the data docking sleeve 5, the pneumatic chuck 4 clamps the data docking sleeve 6, thereby realizing the data docking transmission and material feeding of the tool head component 8. When it is necessary to switch the 3D printing component 81, insert the data docking sleeve 6 into the pneumatic chuck 4, and insert the tool slider 9 into the tool head mounting slide rail 13. When the top of the tool slider 9 contacts the upper limit block 14, it means that the lower data exchange spring contact 63 of the data docking sleeve 6 contacts the upper data exchange spring contact 53 of the data docking sleeve 5, realizing the data transmission of the tool head component 8. The lower feeding channel 62 is aligned with the upper feeding channel 52 to realize the feeding of the 3D printing component 81. When it is necessary to replace the laser micro-engraving component 82 and the CNC engraving component 83, the replacement process is the same as that of the 3D printing component 81.
