[0041] Exemplary Y-axis single-drive pendulum mechanism

[0042] like Figure 5-Figure 6As shown, further, some embodiments of the present invention provide a specific structure of a Y-axis single-drive swing mechanism 5, wherein the Y-axis single-drive swing mechanism 5 of this structure includes a Y-axis single arm 51 and a Y-axis driving unit 52.

[0043] Example A-axis power head

[0044] like Figure 7 As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned A-axis power head 6. The A-axis power head 6 of this structure includes an A-axis reduction module 61 and an A-axis reduction motor 62. In order to install the above-mentioned A-axis reduction module 61 and A-axis reduction motor 62, an A-axis fixing groove 511 is provided at the end of the Y-axis single arm 51. Therefore, the A-axis reduction module 61 can be installed in the A-axis fixing groove 511, and the A-axis reduction motor 62 is installed on the A-axis reduction module 61 and located inside the A-axis fixing groove 511. In this way, the A-axis power head 6 can be stored in the Y-axis single arm 51. Through the design of the above-mentioned structure, the A-axis power head 6 of this structure is relatively compact and can be used in conjunction with the Y-axis single arm 51 to achieve the advantage of small footprint. Therefore, when the A-axis reduction motor 62 is started, it drives the A-axis reduction module 61 to rotate, and then the A-axis reduction module 61 drives the B-axis power head 7 to rotate to achieve the processing of the structural parts.

[0045] Exemplary B-axis power head

[0046] like Figure 7As shown, further, some embodiments of the present invention provide a specific structure of a B-axis power head 7, wherein the B-axis power head 7 of this structure includes a B-axis drive seat 71 and a B-axis machining motor 72, wherein the B-axis drive seat 71 is installed on the output end of the A-axis reduction module 61, and the B-axis machining motor 72 is movably installed in the B-axis drive seat 71, so when the output end of the above-mentioned A-axis reduction module 61 drives the B-axis drive seat 71 to rotate, the B-axis drive seat 71 drives the B-axis machining motor 72 to rotate as well, and here the B-axis machining motor 72 can drive the machining tool to rotate, so in this way, the machining tool can be rotated while also performing corresponding movements on the above-mentioned X-axis, Y-axis, Z-axis, and A-axis, thereby realizing the five-axis machining center to process the structural parts of new energy vehicles.

[0047] Exemplary B-axis drive mount

[0048] Furthermore, in order to realize the swing of the B-axis processing motor 72 in the B-axis drive seat 71, some embodiments of the present invention provide a specific structure of the B-axis drive seat 71. The B-axis drive seat 71 of this structure includes a drive shell 711 and an internal drive part 712. Specifically, the drive shell 711 is installed on the output end of the A-axis reduction module 61, so that the A-axis reduction module 61 can drive the drive shell 711 to rotate within the range of 0-360 degrees after rotation, and the internal drive part 712 is installed in the left drive part 713 of the drive shell 711. Here, the B-axis processing motor 72 is driven to swing in the drive shell 711 by the internal drive part 712, wherein an inner right drive shaft 714 is installed on the right side of the B-axis processing motor 72, and the inner right drive shaft is rotatably connected to the right drive part 715 of the drive shell 711, and the inner drive part 712 is rotatably connected to the left side of the B-axis processing motor 72. Through the design of the above structure, the B-axis drive seat 71 of this structure can better drive the B-axis processing motor 72 to swing, so as to realize the processing of structural parts of new energy vehicles.

[0049] Through the design of the above structure, it is further realized that the five-axis machining center can have the functions of drilling, milling, tapping and other functions of processing horizontal and vertical planes, and can process drilling and tapping at spatial angles.

[0050] like Figure 8As shown, further, in some embodiments of the present invention, a chip removal groove 11 is opened on the machine tool base 1, and a chip removal screw 12 is further installed in the chip removal groove 11. Correspondingly, a chip removal drive motor 13 is installed on the left side of the machine tool base 1, and a chip removal barrel 14 is installed on the right side. The chip removal barrel 14 is connected to the chip removal groove 11, and the left end of the chip removal screw 12 is rotatably connected to the chip removal drive motor 13, and the right end of the chip removal screw 12 is rotatably connected to the chip removal barrel 14, so that the chips generated during the processing can enter the chip removal groove 11, and the chip removal drive motor 13 starts to drive the chip removal barrel 14. After the movement, the chip removal screw 12 is driven to rotate, and the chips in the chip removal groove 11 are moved into the chip removal barrel 14 under the drive of the chip removal screw 12. A chip removal port is provided at the bottom of the chip removal barrel 14, so after the chips enter the chip removal barrel 14, they are collected outside the machine tool base 1 through the chip removal port, which greatly improves the chip cleaning efficiency. In addition, the chip removal screw 12 and chip removal drive motor 13 components of the above structure are integrated on the machine tool base 1, which increases the practicality of the five-axis machining center and eliminates the need for additional chip removal equipment, thereby reducing machining costs.

[0051] It can be understood that the front side of the machine tool base 1 is a sloped seat surface 101, so that the chips falling on the seat surface 101 can slide into the chip removal groove 11, which greatly reduces the difficulty of manual cleaning of the chips.

[0052] Exemplary Support Leg Module

[0053] Generally speaking, most existing five-axis machining centers lack vibration and anti-sway features, which can easily reduce the service life of parts due to prolonged vibration and shaking. Therefore, some embodiments of the present invention provide support leg modules. By disposing multiple support leg modules 8 at the bottom of the machine tool base 1, the entire five-axis machining center can effectively provide vibration and anti-sway features, reducing the impact of vibration and shaking on parts during machining and improving the machining quality of structural parts.

[0054] like Figures 9-12 As shown, the support leg module 8 of the structure includes a vertical support leg rod 81, a support pad 82, and an anti-sway frame mechanism 83. Specifically, the anti-sway frame mechanism 83 is installed on the above-mentioned support pad 82, and the vertical support leg rod 81 is installed on the anti-sway frame mechanism 83 and connected to the bottom of the machine tool base 1. Here, the above-mentioned anti-sway frame mechanism 83 includes an upper anti-sway mechanism 84 and a lower anti-sway mechanism 85. Here, the lower anti-sway mechanism 85 is installed on the support pad 82, and the upper anti-sway mechanism 84 is installed on the lower anti-sway mechanism 85, and the vertical support leg rod 81 is specifically installed in the upper anti-sway mechanism 84. The upper anti-sway mechanism 84 and the lower anti-sway mechanism 85 cooperate with each other to provide longitudinal and lateral elastic support for the vertical support leg rod 81, thereby reducing the occurrence of vibration and shaking.

[0055] Furthermore, the above-mentioned upper anti-sway mechanism 84 can provide lateral elastic support for the vertical support leg rod 81. In order to achieve the above-mentioned purpose, the upper anti-sway mechanism 84 here includes a plurality of parcel rack parts 841 connected in sequence. Here, the vertical support leg rod 81 can be fixed by the plurality of parcel rack parts 841, and the plurality of parcel rack parts 841 can also fix vertical support leg rods 81 of different sizes, which greatly improves the practicality and versatility of the support leg module 8.

[0056] The parcel shelf 841 includes a first vertical rod 842, a transverse elastic push rod 843, an upper shelf plate 844, and a C-shaped parcel spring plate 845. Specifically, the first vertical rod 842 is mounted on the lower anti-sway mechanism 85, and the transverse elastic push rod 843 is mounted on the upper part of the first vertical rod 842. The upper shelf plate 844 is mounted on the transverse elastic push rod 843. The C-shaped parcel spring plate 845 is movably connected to the upper shelf plate 844 through two anti-sway telescopic parts 86. The number can be designed to be 3 groups, so 3 groups of C-shaped wrapping spring plates 845 can wrap the vertical leg rod 81. Furthermore, a plurality of convex spring blocks 846 are designed on the inner wall of the C-shaped wrapping spring plate 845. The plurality of convex spring blocks 846 can further press against the outer wall of the vertical leg rod 81, thereby increasing the friction between the vertical leg rod 81 and the C-shaped wrapping spring plate 845. In this way, when vibration and shaking occur, the C-shaped wrapping spring plate 845 can continue to adhere to the vertical leg rod 81.

[0057] Furthermore, an inner groove 847 is provided on the inner surface of the upper frame plate 844, and an inner anti-sway component is installed in the inner groove 847. The inner anti-sway component includes an inner spring body 848 and two inner hinge seats 489, wherein the two inner hinge seats 489 can be rotatably installed on both sides of the inner groove 847, and the inner spring body 848 is installed between the two inner hinge seats 489 to facilitate the inner hinge seats 489 to reset after rotation; and two anti-sway telescopic components 86 are installed between the C-shaped wrapped spring plate 845 and the upper frame plate 844, so when the C-shaped wrapped spring plate 845 transmits vibration and shaking to the upper frame plate 844, the anti-sway telescopic components 86 can offset a part of the vibration movement;

[0058] Among them, the above-mentioned anti-sway telescopic component 86 includes a first spring 861, a telescopic tube 862, and a telescopic inner rod 863. One end of the telescopic inner rod 863 is hinged to the outer side of the inner hinge seat 489, and the other end of the telescopic inner rod 863 is installed in one end of the telescopic tube 862. The first spring 861 is sleeved on the telescopic tube 862 and the telescopic inner rod 863, and the other end of the telescopic tube 862 is connected to the outer wall of the C-shaped wrapped spring plate 845 through the hinge block 864. Therefore, when vibration and shaking are transmitted, the first spring 861 is compressed, and then the telescopic inner rod 863 moves into the telescopic tube 862. At this time, the first spring 861 can submit elastic force to reset the anti-sway telescopic component 86, and then the two anti-sway telescopic components 86 on the C-shaped wrapped spring plate 845 can provide elastic support for it to prevent the vertical support leg rod 81 from vibrating and shaking in the horizontal direction.

[0059] like Figure 13-14 As shown, further, the above-mentioned lower anti-sway mechanism 85 provides longitudinal elastic support for the vertical leg rod 81. In order to achieve the above-mentioned purpose, the lower anti-sway mechanism 85 includes a lower frame seat plate 851, multiple transverse elastic pull rods 852, multiple second vertical rods 853, multiple second springs 854, and multiple spring cylinders 855, wherein multiple spring cylinders 855 are evenly installed in the middle of the upper surface of the support pad 82, and the second spring 854 is installed in the spring cylinder 855, while the multiple second vertical rods 853 are evenly distributed on the outside of the upper surface of the support pad 82. 851 is installed on the upper end of the second spring 854, and the above-mentioned first vertical rod 842 is installed on the lower frame seat plate 851, and then the lower end of the vertical support leg rod 81 is pressed against the lower frame seat plate 851; a transverse elastic pull rod 852 is installed between the upper part of the second vertical rod 853 and the outer wall of the lower frame seat plate 851, and the two are connected by the transverse elastic pull rod 852. In this way, the lower frame seat plate 851 is provided with elastic support in the longitudinal direction by multiple second springs 854, thereby providing elastic support for the above-mentioned vertical support leg rod 81 in the longitudinal direction to reduce the impact of vibration and shaking. At the same time, through the provision of multiple transverse elastic pull rods 852, the lower anti-sway mechanism 85 also has the function of preventing sway in the transverse direction, greatly increasing the functionality of the entire support leg module 8, and can better provide shock absorption and anti-sway functions for the entire five-axis machining center, reducing the impact of vibration and shaking on parts during machining, and also improving the machining quality of structural parts.
