[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] First, by adopting the transmission mode of roller linear guide, which has the characteristics of high precision, high rigidity, low friction and long life, the high precision and high rigidity characteristics can effectively alleviate the problem of small load-bearing capacity of existing five-axis vertical machining center, which affects the machining accuracy;

[0017] Secondly, the slider is used to increase the contact between the workbench and the saddle, effectively enhancing the support and load-bearing capacity. By setting several sliders, the distance between the sliders is effectively shortened, thereby evenly sharing the workpiece load, increasing the load, reducing wear, and avoiding the problem of the workbench being suspended or deformed, further improving the processing accuracy.

The vibration-damping material effectively increases the weight of the base and the column and lowers the center of gravity. When the five-axis vertical machining center vibrates, the vibration-damping material in the shielding member can absorb and disperse the vibration of the five-axis vertical machining center, thereby reducing the overall vibration of the five-axis vertical machining center and effectively eliminating the vibration caused by machining, thereby improving the machining accuracy of the five-axis vertical machining center.

[0027] Example:

[0028] A five-axis vertical machining center, such as Figure 1-Figure 4 As shown, it includes a base 1, a column 2, a workbench 3, a saddle 4, a machine head 5 and a rotary workbench 6 installed on the workbench 3, wherein the rotary workbench 6 adopts a precision CNC rotary workbench 6, which has the advantages of high precision, high rigidity, stability and reliability, and easy operation. A roller linear rail 7 is arranged between the workbench 3 and the saddle 4. The roller linear rail 7 has the characteristics of high precision, high rigidity, low friction and long life. The high precision and high rigidity characteristics are utilized to effectively alleviate the problem that the existing five-axis vertical machining center has a small load-bearing capacity and affects the machining accuracy. At the same time, a slider 8 for abutting the saddle 4 is arranged on the side of the workbench 3 close to the saddle 4. The slider 8 is utilized to increase the contact between the workbench 3 and the saddle 4, effectively enhance the support, improve the load-bearing capacity, and further improve the machining accuracy.

[0029] A plurality of sliders 8 are provided, and the load-bearing capacity is effectively increased by increasing the number of sliders 8, and the spacing between the sliders 8 is effectively shortened, thereby evenly sharing the workpiece load, increasing the load, and reducing wear. The sliders 8 are symmetrically arranged on both sides of the roller linear rail 7 to avoid the problem of the worktable 3 being suspended or deformed, thereby further improving the processing accuracy.

[0030] A plurality of reinforcing ribs 9 are also provided on one side of the workbench 3 close to the saddle 4. The reinforcing ribs 9 are used to enhance the overall rigidity of the workbench 3 and improve the load-bearing capacity. At the same time, compared with the existing operation of increasing the load-bearing capacity by thickening the workbench 3, the weight of the workbench 3 is effectively reduced, and the load on the X-axis motor is greatly reduced.

[0031] The saddle 4 is an integrally formed casting, and is provided with an X-axis motor placement area X10 and an X-axis tailstock bearing seat X11. While ensuring the normal use of the saddle 4, the rigidity of the casting during axial movement is greatly improved, the durability is good, and it is not easy to shake, which further improves the processing accuracy.

[0032] Both the base 1 and the column 2 are provided with a cavity 12 inside, and both the base 1 and the column 2 are provided with a through hole 13 connected to the outside, and a plurality of shielding members 14 are provided in the cavity 12, and a vibration-damping material is injected into the cavity 12, and then the through hole 13 is blocked by the shielding member 14 to prevent the vibration-damping material from overflowing, and the vibration-damping material is used to increase the weight of the base 1 and the column 2 and lower the center of gravity, thereby effectively improving the stability of the overall structure, and when the five-axis vertical machining center vibrates, the vibration-damping material can absorb and disperse the vibration of the five-axis vertical machining center, thereby reducing the overall vibration of the five-axis vertical machining center, effectively eliminating the vibration caused by machining, and thus improving the machining accuracy of the five-axis vertical machining center.

[0033] The vibration reduction material is a damping material, which has a good ability to dissipate vibration energy and improve the effect of eliminating vibration.

[0034] Auxiliary ribs 15 are provided at the positions of the base 1 corresponding to the Y-axis motor and the Y-axis tailstock bearing seat X11. The auxiliary ribs 15 are used to effectively suppress the thermal expansion caused by the screw during machine tool processing, thereby improving the repeatability of the machine tool.

[0035] Chip removal grooves 16 are integrally formed on both sides of the base 1. The integral molding greatly improves the rigidity, widens and enlarges the bearing surface, and effectively maintains the best dynamic horizontal accuracy.

[0036] The column 2 is an integrally formed casting, and a Z-axis motor bearing seat Z17 is arranged on the column 2. The rigidity is greatly improved through the integral forming. The ribs are arranged vertically and in parallel, and the internal ribs are distributed in a high density. The strength is higher than the existing parallel arrangement, and the processing is smoother and the stability is stronger.

[0037] The machine head 5 is integrally molded and cast, which greatly improves the structural rigidity, effectively prevents the resonance and thermal changes caused by processing, strengthens the cutting rigidity, and the spindle centerline position of the machine head 5 and the Z-axis track position are symmetrically set, effectively eliminating the generation of unbalanced torque and ensuring the accuracy of micro-feed and long-term processing accuracy.

[0038] The plane of the workbench 3 is set to an inverted V-shaped structure, and the inverted V-shaped structure has a V-shaped cross-section along the Y-axis to avoid waste accumulation and have a good chip removal effect. At the same time, it can better cooperate with the chip removal grooves 16 on both sides to improve the chip removal effect.
