[0002] A five-axis linkage gantry milling machine is a CNC machining equipment based on a gantry structure. It integrates the linkage control function of five coordinate axes. The five coordinate axes can move simultaneously and in coordination according to a preset program, allowing the tool or workpiece mounted on the spindle to perform complex trajectory machining in three-dimensional space. Its gantry structure has the characteristics of high rigidity and high load-bearing capacity, making it suitable for machining large and heavy workpieces, reducing the number of workpiece clamping times, and improving machining accuracy and efficiency.

[0003] The machining accuracy adjustment device for a five-axis linkage gantry milling machine is an auxiliary device for improving the machining accuracy of this type of machine tool.

[0032] Specifically, this five-axis linkage gantry milling machine machining accuracy adjustment device improves machining accuracy through the coordinated operation of various mechanisms. The worktable 1 provides stable support, while the machining mechanisms 2 around it enhance accuracy. The hydraulic push rod 201 is fixed to the top right side of the worktable 1, pushing the slide table 202 to move and adjust the workpiece position, ensuring precise positioning with the milling head 204 and reducing machining errors. The gantry frame 203 forms the framework of the machining mechanism 2, and the milling head 204 is responsible for machining. The straightener 205 monitors and corrects accuracy deviations in real time. The conveying assembly 206 ensures stable workpiece transport and reduces interface compatibility issues. The fixed table 2061 is fixed to the worktable. On the front side of platform 1, electric push rod 2062 adjusts its height to match the height of conveyor belt 2066 with other module interfaces, preventing conveyor deformation. Motor 2063 drives turntable 2064 to rotate, which in turn drives turntable 2065 to rotate synchronously through conveyor belt 2066, accurately conveying the workpiece to the processing position and reducing module interface friction and misalignment. Adjustment mechanism 3 works closely with processing mechanism 2 to adjust the angle of milling head 204, straightener 205 corrects deviations, and conveyor component 206 delivers the workpiece accurately. The tight connection and high compatibility of each module interface reduce the decrease in accuracy caused by interface problems and ensure high processing precision.

[0033] Reference Figure 1 , Figure 2 and Figure 5The adjusting mechanism 3 includes a fixed frame 301, which is slidably connected to the right side of the outer wall of the gantry 203. A fixed plate 302 is fixedly connected to the left side of the inner wall of the fixed frame 301. A motor 303 is slidably connected to the middle of the inner wall of the fixed plate 302. A pulley 304 is fixedly connected to the output end of the motor 303. Multiple sliding bars 305 are fixedly connected to the top of the outer wall of the gantry 203. The pulley 304 is slidably connected to one side of the outer wall of the sliding bars 305. A rotating assembly 306 is fixedly connected to the front side of the outer wall of the fixed plate 302. The rotating assembly 306 includes a connecting frame 3061, which is fixedly connected to the right side of the outer wall of the fixed plate 302. A motor 304 is fixedly connected to the top of the outer wall of the connecting frame 3061. The output end of the second motor 3062 is fixedly connected to a bevel gear 3063. The top of the inner wall of the connecting frame 3061 is rotatably connected to a bevel gear 3064, which meshes with the first bevel gear 3063. The bottom of the outer wall of the second bevel gear 3064 is fixedly connected to a threaded rod 3065, which is rotatably connected to the rear side of the outer wall of the milling head 204.

[0034] Specifically, the adjustment mechanism 3 enables multi-dimensional adjustment of the milling head 204. The fixed frame 301 serves as the basic frame, slidably connected to the right side of the outer wall of the gantry 203, providing support and a base for movement for the adjustment mechanism 3. When the motor 303 starts, its output drives the pulley 304 to rotate. The pulley 304 slides on one side of the outer wall of the top slide bar 305 of the gantry 203, causing the fixed plate 302 and the fixed frame 301 to move along the slide bar 305, thus achieving horizontal position adjustment. The rotating component 306 on the front side of the outer wall of the fixed plate 302 is responsible for multi-angle adjustment of the milling head 204. When the second machine 3062 starts, its output end drives the first bevel gear 3063 to rotate, and the second bevel gear 3064 meshing with it rotates accordingly, driving the threaded rod 3065 at the bottom to rotate. This rotates the threaded rod 3065 at the bottom, which acts on the rear side of the outer wall of the milling head 204, realizing the raising or lowering or fine-tuning of the angle of the milling head 204. At the same time, the second electric push rod 3068 on the rear side of the outer wall of the connecting frame 3061 starts, and its output end pushes the first half gear 3066 to move. The second half gear 3067 meshing with it rotates accordingly, assisting in the angle adjustment of the milling head 204, ensuring that it accurately reaches the processing position and meets different processing needs.

[0035] Reference Figure 1 , Figure 2 and Figure 3A control panel 4 is fixedly connected to the rear side of the outer wall of the workbench 1. A power distribution cabinet 5 is fixedly connected to the left side of the outer wall of the control panel 4. A movable frame 6 is fixedly connected to the bottom right side of the workbench 1. Multiple partitions 8 are fixedly connected to the front and rear sides of the outer wall of the workbench 1. Guardrails 7 are fixedly connected to the four sides of the outer wall of the fixed frame 301. A ladder 9 is fixedly connected to the top left side of the workbench 1. A slide 11 is fixedly connected to the middle of the inner wall of the workbench 1. Baffles 10 are fixedly connected to the top left and right sides of the workbench 1.

[0036] Specifically, the control console 4 is fixed to the rear of the workbench 1, and the operation control center can issue commands to regulate the overall operation; the power distribution cabinet 5 is on the left side of the control console 4, which supplies power to the entire workbench 1 system and ensures circuit stability; the movable frame 6 on the bottom right can drive the workbench 1 to move flexibly to adapt to different work position requirements; the multiple partitions 8 on the front and rear sides of the outer wall play the role of separating space and protecting the internal structure; the components around the outer wall of the fixed frame 301 improve the stability of the components; the ladder 9 on the top left side ensures operation safety and prevents personnel or objects from falling accidentally; the slide 11 in the middle of the inner wall provides guidance for the movable parts on the workbench 1, ensuring that they slide smoothly along the predetermined trajectory; the baffles 10 on the top left and right sides can prevent processed materials or tools from slipping.

[0037] Working Principle: This five-axis linkage gantry milling machine machining accuracy adjustment device effectively solves the deformation and deviation problems caused by insufficient module interface connection and compatibility through the close cooperation and precise coordination of various mechanisms, thereby improving machining accuracy. The worktable 1 provides stable support for the whole, and the machining mechanism 2 around its outer wall improves accuracy. The hydraulic push rod 201 is fixed on the top right side of the worktable 1, and its output end pushes the slide 202 to move, which can flexibly adjust the position of the workpiece on the worktable 1, ensuring the accurate relative position of the workpiece and the milling head 204, and reducing machining errors caused by workpiece placement deviation. The gantry frame 203 serves as an important frame for the machining mechanism 2, and the milling head 204 on the right side of the outer wall is responsible for the specific machining operation. The corrector 205 on the front side of the outer wall can monitor the accuracy deviation during the machining process in real time and issue correction signals in a timely manner. The transmission component 206 plays a key role in ensuring the stability of workpiece transportation and reducing interface compatibility problems. The fixed table 2061 is fixed to the outer side of the worktable 1. On the front side of the wall, the electric push rod 2062 at the bottom can adjust the height of the fixed platform 2061, so that the interface height of the conveyor belt 2066 matches that of other modules, avoiding workpiece deformation caused by height difference. After the motor 2063 on the top of the fixed platform 2061 is started, the output end drives the turntable 2064 to rotate. Through the transmission of the conveyor belt 2066, the turntable 2065 rotates synchronously. The conveyor belt 2066 runs smoothly on the top of the fixed platform 2061, accurately conveying the workpiece to the processing position. This transmission method reduces friction and misalignment between the interfaces of modules, reducing the risk of deformation and deviation. The adjustment mechanism 3 works closely with the processing mechanism 2. The adjustment mechanism 3 adjusts the processing angle of the milling head 204. The corrector 205 in the processing mechanism 2 corrects the deviation in real time. The conveyor component 206 accurately conveys the workpiece. The interfaces of each module are closely connected and highly adaptable, which reduces the decrease in processing accuracy caused by interface problems and ensures high processing accuracy.

[0038] The operation of the adjustment mechanism 3 relies on the precise coordination of its components to achieve multi-dimensional adjustment of the milling head 204. The fixed frame 301 serves as the basic frame, slidably connected to the right side of the outer wall of the gantry 203, providing support and a base for movement for the entire adjustment mechanism 3. When motor 1 303 starts, its output drives pulley 304 to rotate. Pulley 304 slides on one side of the outer wall of multiple sliding bars 305 at the top of the gantry 203, thereby driving the fixed plate 302 and the fixed frame 301 to move along the direction of the sliding bars 305, thus achieving horizontal position adjustment of the adjustment mechanism 3. The rotating component 306 on the front side of the outer wall of the fixed plate 302 is responsible for multi-angle adjustment of the milling head 204. After motor 2 3062 starts, its output drives bevel gear 1. When 3063 rotates, bevel gear 3064 meshes with bevel gear 3063, causing bevel gear 3064 to rotate as well. This, in turn, drives the threaded rod 3065 fixedly connected to its bottom to rotate. The threaded rod 3065 acts on the rear side of the outer wall of the milling head 204, enabling the milling head 204 to be raised, lowered, or its angle finely adjusted. At the same time, multiple electric push rods 3068 on the rear side of the outer wall of the connecting frame 3061 are activated, and their output ends push half gear 3066 to move. Since half gear 3067 meshes with half gear 3066, half gear 3067 rotates as well, further assisting the milling head 204 in angle adjustment, ensuring that the milling head 204 can accurately reach the required machining position and meet different machining needs.
