[0039] Reference Figures 1 to 4 , the present invention proposes a dual-force-controlled five-axis machining machine tool, comprising: a base 1 and a sliding seat 2, the sliding seat 2 being slidably connected to the base 1 along a first direction and a second direction;

[0040] The upper end surface of the sliding seat 2 is equidistantly provided with a plurality of adjustment mechanisms 3, the adjustment mechanism 3 comprising a first slide rail group 301, the first slide rail group 301 extending along the second direction, and the first slide rail group 301 is slidably connected to a movable platform 302, the upper end surface of the movable platform 302 is fixedly connected to a second slide rail group 303 extending along the second direction, the second slide rail group 303 is slidably connected to a lifting block 304, along the second direction, the upper end surface and the lower end surface of the lifting block 304 are provided with a first angle, and the upper end surface of the lifting block 304 is fixedly connected to a third slide rail group 305, and the third slide rail group 305 is slidably connected to a bearing platform 306;

[0041] The movable platform 302 is also connected to a fourth slide rail group 307 extending along a third direction, the third direction is perpendicular to the first direction and the second direction respectively, the fourth slide rail group 307 is slidably connected to the bearing platform 306, the upper end surface of the bearing platform 306 is provided with a fixture 4 for fixing the workpiece, and the base 1 is slidably connected to a processing component 5 corresponding to the fixture 4 along the third direction;

[0042] The angle value of the first angle is greater than 0 degree and less than 45 degrees. When the lifting block 304 is driven to slide along the second direction, the carrying platform 306 moves along the third direction.

[0043] In the above embodiment, the efficient processing function of the dual-force-controlled five-axis machining machine tool is realized through the coordinated design of components such as the base 1, the sliding seat 2, the adjustment mechanism 3, the movable platform 302, the lifting block 304 and the bearing platform 306. The base 1, as the basic structure of the machine tool, is slidably connected with the sliding seat 2 along the first direction and the second direction, so that the sliding seat 2 can move accurately in two mutually perpendicular directions, providing a basic multi-degree-of-freedom motion function for the entire machine tool. Combined with the sliding connection between the processing component 5 and the base 1 along the third direction, the processing component 5 corresponds to the bearing platform 306, so that the processing component 5 can accurately process the fixed workpiece in the third direction. The sliding connection between the sliding seat 2 and the base 1, and the sliding connection between the processing component 5 and the base 1, are realized by the operation mode of the lead screw slide, and cooperate with the servo motor to achieve precise digital control.

[0044] The upper end surface of the sliding seat 2 is equidistantly provided with a number of adjustment mechanisms 3, and the adjustment mechanisms 3 are preferably arranged in four groups. Each adjustment mechanism 3 not only ensures the precise adjustment of the processing station, but also enables multiple stations to work in coordination. In the adjustment mechanism 3, the first slide rail group 301 extends along the second direction, and the movable platform 302 slidably connected thereto can achieve high-precision linear motion in the second direction. The upper end surface of the movable platform 302 is fixedly connected with the second slide rail group 303, and the lifting block 304 slidably connected to the second slide rail group 303 is a key component for achieving height adjustment of the bearing platform 306. When the lifting block 304 slides along the second direction, the first angle set on its upper and lower surfaces converts the horizontal linear motion into the lifting motion of the bearing platform 306 in the third direction. The first angle between the upper and lower surfaces of the lifting block 304 can ensure that the lifting block 304 provides stable and precise height adjustment when sliding, and the angle value range of the first angle is set to be greater than 0 degrees and less than 45 degrees. The specific value setting needs to be selected according to the travel of the supporting platform 306 along the second direction and the required lifting distance during actual application.

[0045] At the same time, the lifting and lowering movement of the carrying platform 306 in the third direction is also restricted by the fourth slide rail group 307 that is slidably connected to the movable platform 302, which can prevent the lifting block 304 from moving horizontally during the lifting process and drive the carrying platform 306 to move horizontally. Only the lifting block 304 and the third slide rail group 305 are allowed to move along the second direction, and the carrying platform 306 and the third slide rail group 305 slide. That is, during the lifting and lowering of the carrying platform 306 through the horizontal movement of the lifting block 304, the relative positions of the carrying platform 306 and the movable platform 302 in the second direction and the first direction will not change.

[0046] The upper end surface of the carrying platform 306 is provided with a fixture 4 for fixing the workpiece. The fixture 4 can achieve high-precision fixation according to the shape of the workpiece and processing requirements, providing a reliable basis for the operation of the processing component 5.

[0047] In summary, through the sliding connection between the sliding seat 2 and the base 1 along the first direction and the second direction and the sliding connection between the processing assembly 5 and the base 1 along the third direction, the fixture 4 for fixing the workpiece on the supporting platform 306 can realize flexible movement in three-dimensional space, and through the cooperation of each slide rail group in the adjustment mechanism 3, the workpiece of a single station can be fine-tuned along the second direction and the third direction to compensate for the angular position, and then when multiple stations are processed simultaneously, even if a single station has a deviation, it can avoid the abnormal station from continuing to generate cumulative errors due to following the unified operation of the whole, ensuring that each station can complete the processing task relatively independently and accurately. In addition, the integrated processing station not only greatly reduces the time for transferring and re-clamping the workpiece between different stations, but also can process multiple workpieces at the same time, reducing the dependence on multiple equipment, further optimizing the production process, and improving the processing efficiency of the machine tool.

[0048] refer to Figure 1 , Figure 2 and Figure 4 In one embodiment, the adjusting mechanism 3 also includes a first driving component 308, the first driving component 308 includes a first driving motor, the first driving motor is fixedly arranged on the upper end surface of the sliding seat 2, the output shaft of the first driving motor is connected to a first screw rod, the first screw rod extends along the second direction, and the first screw rod is threadedly connected to a first pushing block, and the first pushing block is fixedly connected to the movable platform 302.

[0049] In the above embodiment, the adjustment mechanism 3 also includes a first drive component 308, which is connected to the movable platform 302 through a first drive motor and a lead screw structure, so that the movable platform 302 can move precisely along the second direction. Specifically, the first drive motor is fixed to the upper end surface of the sliding seat 2, and drives the first lead screw through the output shaft of the motor, and the rotation of the lead screw drives the first push block to slide along the second direction. The first push block is fixedly connected to the movable platform 302, so the force transmitted by the drive motor through the lead screw causes the movable platform 302 to move linearly in the second direction. The accuracy and stability of the platform adjustment are significantly improved, ensuring that each station can be accurately adjusted during multi-station processing to avoid processing deviations caused by mechanical errors.

[0050] In one example, the adjusting mechanism 3 also includes a second driving component 309, the second driving component 309 includes a second driving motor, the second driving motor is fixedly arranged on the upper end surface of the movable platform 302, the output shaft of the second driving motor is connected to a second screw rod, the second screw rod extends along the second direction, and the second screw rod is threadedly connected to a second pushing block, and the second pushing block is fixedly connected to the lifting block 304.

[0051] In the above embodiment, the second drive assembly 309 is composed of a second drive motor and a second screw rod. The second drive motor is fixed to the upper end surface of the movable platform 302, and the output shaft of the motor is connected to the second screw rod. The second screw rod extends along the second direction, and the second push block is driven to slide along the second direction by the rotation of the screw rod. The second push block is fixedly connected to the lifting block 304, so the function of the second drive assembly 309 is to drive the lifting block 304 to move along the second direction through the second push block.

[0052] In combination with the above-mentioned embodiment, the first driving assembly 308 controls the movement of the movable platform 302 through a screw system, and the second driving assembly 309 further optimizes the adjustment accuracy of the lifting block 304 by controlling the lifting and lowering of the lifting block 304 .

[0054] An accommodating chamber is formed in the rotating arm 8 , and the accommodating chamber is provided with a plurality of the processing components 5 corresponding to the plurality of the jigs 4 .

[0055] In the above embodiment, a support frame 6 extending along the third direction is provided on the upper end surface of the base 1, and the support frame 6 provides basic support for the processing operation and provides a sliding track for the U-shaped support arm 7, so that the support arm 7 can move along a specific path. On both sides of the inner side of the support arm 7, a rotating arm 8 is installed through a rotating connection, so that the rotating arm 8 can rotate around the axis of the support arm 7, thereby increasing the flexibility of processing, enriching the types of processes, and being able to use a variety of processing tools.

[0056] A rotary motor 9 is disposed on one side of the support arm 7. The output shaft of the rotary motor 9 is connected to a reducer, which is further connected to the rotary arm 8, ensuring that the rotary arm 8 can rotate at a stable speed and force, providing a reliable power source for the processing process. Driven by the rotary motor 9, the rotary arm 8 can drive the processing assembly 5 inside it to rotate, thereby achieving precise processing of the workpiece.

[0057] The rotating arm 8 is designed with a receiving chamber inside, and the chamber is provided with a plurality of processing components 5 according to the processing requirements. Each processing component 5 corresponds to a fixture 4, which ensures the efficiency and accuracy of the processing process. The dual-force-controlled five-axis machining machine tool can process multiple workpieces at the same time, greatly improving the production efficiency.

[0058] refer to Figure 1 and Figure 5 In one embodiment, the processing assembly 5 includes two double-headed motors 51 arranged perpendicular to each other, and the two double-headed motors 51 are staggered, and two opposite output shafts of the double-headed motors 51 are respectively connected to the first processing part 52 and the second processing part 53;

[0060] In the above embodiment, the two double-headed motors 51 are arranged perpendicular to each other and staggered. Such a layout not only saves space, but also enables the machine tool to perform more dimensional processing operations within a limited range. Each double-headed motor 51 has two relative output shafts, which are respectively connected to the first processing part 52 and the second processing part 53. Each processing part can carry different processing tools, so that different processes can be performed at the same workstation, which significantly improves processing efficiency and prevents frequent clamping from causing cumulative errors.

[0061] The rotating arm 8 is also provided with a transmission hole in order to match the output shaft of the double-headed motor 51. The transmission hole not only ensures the accuracy of power transmission, but also realizes a stable connection to the double-headed motor 51 through the sealing fixing plate 10 on the side facing away from the double-headed motor 51. The sealing fixing plate 10 effectively prevents debris or liquid that may be generated during the processing from entering the transmission system, thereby ensuring the long-term stable operation of the machine tool.

[0073] In the above embodiment, M-shaped connecting wing plates 376 are provided on both sides of the bearing plate 356, and the avoidance gaps of the connecting wing plates 376 allow the first push block to pass through unhindered and achieve a stable fixed connection with the movable platform 302. This design ensures the continuity and accuracy of power transmission.

[0074] The inner side of the connecting wing plate 376 is slidably connected to the fourth slide rail group 307, so that when the lifting block 304 slides along the second direction, the supporting platform 306 can move synchronously along the third direction, which not only ensures the smoothness and continuity of the movement, but also prevents the supporting platform 306 from being displaced in the first direction and the second direction relative to the movable platform 302 through the precise guidance of the slide rail group, thereby effectively avoiding deviations and errors during the movement.

[0075] refer to Figure 1 and Figure 2 In one embodiment, two groups of liquid spraying components 16 are further included, and the liquid spraying components 16 include a plurality of nozzles 161 for spraying processing fluid. A protective cover 17 is provided on the upper end surface of the support arm 7. The liquid spraying components 16 are provided on the side of the protective cover 17 away from the support frame 6 and the side of the carrying platform 306 away from the support frame 6. Both groups of the liquid spraying components 16 are directed toward the fixture 4.

[0076] In the above embodiment, the dual force-controlled five-axis machining center is also provided with two groups of spray components 16 to improve the processing efficiency during the machining process. When the machine tool is used as a milling machine, coolant is sprayed to reduce the cutting temperature and reduce tool wear; and when the machine tool is used as a grinder or grinding, grinding fluid is sprayed to facilitate the smooth progress of the grinding process and improve the quality of the workpiece surface. The setting of the two groups of spray components 16 enables the machine tool to flexibly adjust the type and amount of spray liquid according to different processing requirements, thereby maximizing the processing efficiency. At the same time, the design of the protective cover 17 not only effectively prevents the splashing of the machining fluid, but also protects the internal structure of the machine tool and the safety of the operator.

[0077] The liquid spray assembly 16 is composed of a plurality of nozzles 161, which are evenly distributed to ensure that the processing liquid can fully cover the fixture 4 and the workpiece. The protective cover 17 configured on the upper end surface of the support arm 7 not only protects the nozzle 161, but also guides the flow of the processing liquid, reduces splashing, and prevents processing debris from hitting the machine itself. The other side of the supporting platform 306 opposite to the support frame 6 is also equipped with a liquid spray assembly 16. The two groups of liquid spray assemblies 16 are arranged facing each other, forming a double-sided spray on the fixture 4, enhancing the spray effect.
