Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a five-axis vertical machining center. Background Technology

[0002] In the machining industry, five-axis vertical machining centers play a vital role in the machining of complex parts due to their high efficiency and precision. However, in traditional five-axis vertical machining centers, the angle adjustment of the indexing plate often relies on only one axis, which greatly limits the adjustment range of the indexing plate.

[0003] When dealing with workpieces with complex curved surfaces and multi-angle machining requirements, the indexing plate cannot be adjusted to the required angle, necessitating multiple clamping operations. This not only affects machining accuracy due to clamping errors, leading to a decline in product quality, but also significantly increases machining time, reduces production efficiency, and makes it difficult to meet the high-precision and high-efficiency machining requirements of modern manufacturing.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figures 1-3 As shown, a five-axis vertical machining center is provided, including a stand 1, a base 2, an X-axis module 3, a Y-axis module 4, an adjustment mechanism 5, a Z-axis module 6, and a spindle 7. The X-axis module 3, Y-axis module 4, and Z-axis module 6 are all motor and lead screw drive structures, which are existing technologies and will not be described in detail here.

[0031] The support 1 is L-shaped, which provides stable support for the entire equipment, enhances its rigidity during processing, and reduces the impact of vibration on processing accuracy. The base 2 is fixed to the support 1, serving as the basic load-bearing component of the equipment and providing an installation platform for other modules. The X-axis module 3 is fixed to the base 2, and its function is to drive related components to move linearly in the X-axis direction, realizing the left and right adjustment of the processing position.

[0032] The Y-axis module 4 is fixed to the X-axis module 3 and, driven by the X-axis module 3, moves along the Y-axis along with itself and the components above it, achieving position adjustment in the forward and backward directions. The adjustment mechanism 5 is fixed to the Y-axis module 4 and is used to install and adjust the angle of the workpiece. The Z-axis module 6 is fixed to the stand 1 and positioned above the adjustment mechanism 5, enabling the spindle 7 to move up and down in the Z-axis direction to meet different depth machining requirements. The spindle 7 is fixed to the Z-axis module 6 and is used to install cutting tools for cutting and other machining operations on the workpiece.

[0033] The adjustment mechanism 5 includes a fixed frame 51, a movable seat 52, an indexing plate 53, a first rotating mechanism 54, and a second rotating mechanism 55. The fixed frame 51 is U-shaped and fixed to the Y-axis module 4. A first movable gap is formed in the middle of the fixed frame 51, which provides space for the rotation of the movable seat 52. The movable seat 52 is U-shaped and movably disposed within the first movable gap. A second movable gap is formed in the middle of the movable seat 52, and the indexing plate 53 is movably disposed within the second movable gap. This structural layout ensures that the movements of the movable seat 52 and the indexing plate 53 do not interfere with each other, improving the flexibility of adjustment.

[0034] The first rotating mechanism 54 is fixed to the fixed frame 51 and the movable seat 52, respectively, and drives the movable seat 52 to rotate. The first rotating mechanism 54 includes a first motor 541, a first rotating shaft, a first fixed seat 542, a first fixed shaft, and a first bearing. The first motor 541 is fixed to the fixed frame 51 and disposed on one side of the movable seat 52, providing power for the rotation of the movable seat 52. The first rotating shaft is fixed to the first motor 541 and the movable seat 52, respectively, transmitting the power of the first motor 541 to the movable seat 52, thereby driving the movable seat 52 to rotate.

[0035] The first rotating shaft is fixed to one end of the movable seat 52, and the first fixed shaft is fixed to the other end of the movable seat 52. The first fixed seat 542 is fixed to the fixed frame 51 and is disposed on one side of the movable seat 52. The first bearing is fixed to the side of the first fixed seat 542, and the first fixed shaft is fixed to the first bearing. The arrangement of the first fixed seat 542, the first fixed shaft, and the first bearing can enhance the stability of the movable seat 52 during rotation, reduce shaking, and improve the accuracy of angle adjustment.

[0036] The second rotating mechanism 55 is fixed to the movable base 52 and the indexing plate 53 respectively, and drives the indexing plate 53 to rotate. The first rotating mechanism 54 and the second rotating mechanism 55 are arranged perpendicularly. The second rotating mechanism 55 includes a second rotating motor 551 and a second rotating shaft 552. The second rotating motor 551 is fixed to the movable base 52, and one end of the second rotating shaft 552 is fixed to the second rotating motor 551, and the other end is fixed to the indexing plate 53. The power provided by the second rotating motor 551 is transmitted to the indexing plate 53 through the second rotating shaft 552, driving the indexing plate 53 to rotate. Because the first rotating mechanism 54 and the second rotating mechanism 55 are arranged perpendicularly, the indexing plate 53 can be adjusted in two mutually perpendicular directions, greatly expanding the angle adjustment range.

[0037] The working process of this five-axis vertical machining center is as follows: When a workpiece needs to be machined, it is fixed on the indexing plate 53. According to the machining requirements, the spindle 7 and the cutting tool are adjusted to the approximate machining position through the coordinated movement of the X-axis module 3, Y-axis module 4, and Z-axis module 6. Then, according to the required machining angle of the workpiece, the first rotary mechanism 54 is activated. The first motor 541 drives the first rotating shaft to rotate, which in turn drives the movable seat 52 to rotate within the first movable gap, achieving angle adjustment of the indexing plate 53 in one direction. Simultaneously, the second rotary mechanism 55 can be activated. The second rotary motor 551 drives the indexing plate 53 to rotate within the second movable gap via the second rotary shaft 552, achieving angle adjustment of the indexing plate 53 in the vertical direction. Through the synergistic action of the two rotary mechanisms, the indexing plate 53 can be adjusted to any required angle to meet the multi-angle machining requirements of complex workpieces. After the angle adjustment is completed, the Z-axis module 6 drives the spindle 7 to move downwards, and the cutting tool on the spindle 7 performs the machining operation on the workpiece.

[0038] The five-axis vertical machining center provided in this application is equipped with a first rotating mechanism 54 and a second rotating mechanism 55 that are perpendicular to each other. These mechanisms can drive the indexing plate 53 to rotate in two vertical directions. Compared with the traditional indexing plate 53 that only adjusts the angle through a single rotating axis, this expands the angle adjustment range and can meet the multi-angle machining needs of various complex workpieces. Due to the large angle adjustment range, the number of times the workpiece needs to be clamped can be reduced, avoiding clamping errors caused by multiple clamping, thereby improving the machining accuracy and efficiency of the workpiece and ensuring product quality.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
