[0028] In this three-axis positioner, two trapezoidal, symmetrically arranged support seats form a workspace adapted to upstream and downstream processes through a preset height. The spacing provides redundancy for the internal mechanism's movement, ensuring overall stability and spatial compatibility. The hollow connecting part with open ends serves as the connecting carrier between the support seats and the rotary mechanism, accommodating transmission components to achieve power transmission. The symmetrical layout of the two parts also makes the rotation force more balanced, improving operational stability. The H-shaped rotary mechanism, with its high-strength torsional resistance, bears the load. Combined with the rotation function around the axis of the connecting part, it gives the workpiece circumferential posture adjustment capability, expanding the processing adaptation scenarios. The block-shaped flipping mechanism at both ends integrates drive components in a compact form. The symmetrical distribution achieves balanced flipping of the placed parts, supplementing the pitch angle adjustment dimension. The cuboid placed parts, through adapting to tooling and connecting flipping actions, transmit multi-degree-of-freedom posture adjustment to the workpiece. Through the synergy of "support-connection-motion-bearing", it meets the precise requirements of complex processes for workpiece posture, helping to carry out efficient automated processing.

[0038] This utility model's three-axis positioner is an advanced welding auxiliary device that integrates high precision, high flexibility, and strong load capacity. It is applied in the automotive manufacturing field, providing robots with additional degrees of freedom of movement, adjusting the position and posture of the workpiece, placing the workpiece to be processed in the optimal processing position, improving processing accuracy and efficiency, and expanding the robot's ability to process complex-shaped workpieces.

[0039] Specific references Figures 1-2 As a specific embodiment of the three-axis positioner of this utility model, the three-axis positioner includes: a support base 110, a connecting part 210, a rotating mechanism 310, a flipping mechanism 410, and a placement part 510.

[0040] The support base 110 is a trapezoidal structure with a preset height. Two support bases 110 are provided, with a preset distance between them. The trapezoidal structure provides strong stability and a reliable support foundation. The two support bases, with a preset distance between them, form a symmetrical support layout, ensuring the overall structural balance. The two support bases 110 respectively support the upper connecting part 210, the rotating mechanism 310, and other components. The preset height meets the equipment installation space requirements, while the preset distance provides movement space for the middle rotating mechanism 310. Simultaneously, the mechanical properties of the trapezoidal structure distribute the load, enhancing the overall rigidity of the equipment.

[0041] Furthermore, such as Figure 1 As shown, the support base 110 is designed with a trapezoidal structure, which utilizes the good stability of the trapezoid to firmly support the components above. Two supports are set at a preset distance to form a stable support structure, like the foundation of a building, ensuring that the entire equipment will not shake or tip over during operation, and providing a stable foundation for the installation and operation of subsequent components.

[0042] The connecting part 210 is a hollow structure with openings at both ends. Two connecting parts 210 are located on the top of the support base 110. The hollow structure facilitates the passage or accommodation of internal cables, pipes, or rotating shafts, while the openings at both ends are likely for connection to the rotary mechanism 310. As the connection medium between the support base 110 and the rotary mechanism 310, the axis of the hollow structure may serve as the axis of rotation for the rotary mechanism 310, enabling it to rotate around the axis of the connecting part 210, achieving horizontal rotation while transmitting the power and load of the rotational motion.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the hollow component located at the top of the support base 110, with openings at both ends, is the connecting part 210. It connects the support base 110 and the rotary mechanism 310. The two connecting parts 210 correspond to the two support bases 110, and their axes determine the central axis of rotation of the rotary mechanism 310. The rotary mechanism 310 rotates around this axis to achieve the function of horizontal rotation, and it also undertakes the function of transmitting power and load.

[0044] The rotating mechanism 310 has an I-beam structure and is positioned between two support seats 110, connected to them via two connecting parts 210. The rotating mechanism 310 can rotate along the axis of the two connecting parts 210. The upper and lower flanges and web of the I-beam structure enhance structural strength and facilitate connection with components such as the connecting parts 210 and the tilting mechanism 410. Rotation along the axis of the connecting parts 210 enables the horizontal rotation of the entire rotating mechanism 310, thereby adjusting the orientation of the tilting mechanisms 410 and the placement component 510 at both ends. As the core rotating component of the equipment, it coordinates with the tilting mechanisms 410 to achieve multi-directional displacement of the workpiece. The I-beam structure design balances strength and lightweight, ensuring stability and accuracy during rotation.

[0045] Furthermore, such as Figure 1 As shown, the component with an I-beam structure located between the two support bases 110 is the rotary mechanism 310. It is connected to the support base 110 through the connecting part and can rotate around the axis of the connecting part, just like the rotating part of a revolving door. It rotates together with the flipping mechanism 410 at both ends and the placement member 510, so that the placement member 510 can change its position in the horizontal direction, making it possible to perform processing operations in different directions.

[0046] The flipping mechanism 410 is a block structure. Two flipping mechanisms 410 are provided, one at each end of the rotary mechanism 310. Drive components can be integrated within the block structure. The placement component 510 is connected to the flipping mechanism 410 at both ends. The flipping mechanism 410 drives the placement component 510 to flip between the two ends of the rotary mechanism 310, adjusting the angle of the placement component 510, such as tilting or pitching. This, in conjunction with the rotary mechanism 310, enables two-dimensional movement of the workpiece, allowing the workpiece to face the processing equipment in different postures, meeting the angle requirements of complex processing techniques.

[0047] Furthermore, such as Figure 1 As shown, at both ends of the rotary mechanism 310, the block-like components are the flipping mechanisms 410. They act as "joints" for the placement component 510. The two flipping mechanisms 410 are located at both ends of the rotary mechanism 310, driving the placement component 510 to flip, allowing the placement component 510 to change its angle like turning pages in a book, thus meeting the requirements of different processing techniques for the workpiece's posture.

[0048] The placement component 510 has a ladder-shaped structure. Both ends of the placement component 510 are positioned between the two ends of the rotary mechanism 310 via a flipping mechanism 410. The placement component 510 can adjust its angle by flipping on the rotary mechanism 310 via the flipping mechanism 410. The placement component 510 has a cuboid structure, with both ends mounted between the two ends of the rotary mechanism 310 via the flipping mechanism 410. The ladder-shaped structure facilitates standardized design, and its surface can be provided with positioning holes, fixture mounting slots, etc., for fixing the workpiece. Driven by the flipping mechanism 410, the placement component 510 can flip on the rotary mechanism 310 to adjust its own angle; simultaneously, it rotates as a whole with the rotary mechanism 310, changing its spatial position. As a workpiece carrying platform, through precise flipping and rotary movements, the workpiece is delivered to the designated position and adjusted to the optimal processing posture, improving the efficiency and accuracy of automated processing.

[0049] Furthermore, such as Figure 1 As shown, the rectangular component located between the two ends of the rotary mechanism 310 is the placement component 510. It is a platform used to support the actual workpiece being processed. It adjusts its own angle through the flipping mechanism 410 and rotates together with the rotary mechanism 310, which can accurately deliver the workpiece to the appropriate position and posture, facilitating welding, assembly and other processing operations.

[0050] In this embodiment, the rotary mechanism 310 includes a transmission arm 311, a first operating arm 312, and a second operating arm 313. The transmission arm 311 is a rod-shaped structure with a preset length, and its two ends are respectively connected to two connecting parts 210. The first operating arm 312 is a long strip structure and is disposed between the transmission arm 311 and the connecting part 210. The first operating arm 312 and the transmission arm 311 are vertically connected. The second operating arm 313 is a long strip structure and is disposed between the transmission arm 311 and the connecting part 210. The second operating arm 313 and the transmission arm 311 are vertically connected. The two ends of the first operating arm 312 and the second operating arm 313 are provided with connecting shafts. The transmission arm 311 of the rotary mechanism 310 is made of high-strength aluminum alloy or alloy steel, and its preset length is determined according to the workpiece size and processing requirements. Its two ends are rigidly connected to the rotary bearing 211 and the vibrator 212 of the connecting part 210 through flanges. Both the first operating arm 312 and the second operating arm 313 are made of hollow steel profiles with rectangular cross-sections, and are vertically fixed to the transmission arm 311 by welding or bolts to form a stable L-shaped structure. High-precision bearing seats are respectively provided at both ends of the first operating arm 312 and the second operating arm 313. The connecting shaft is installed in the bearing seats by interference fit and is axially fixed by locking nuts to ensure that the rotation accuracy of the connecting shaft is within ±0.05mm.

[0051] In this embodiment, the flipping mechanism 410 is located at both ends of the first operating arm 312. The flipping mechanism 410 is connected to the connecting shaft of the first operating arm 312. The main frame of the flipping mechanism 410 is made of cast steel or welded structure and is flexibly connected to the connecting shaft at both ends of the first operating arm 312 through a universal joint. A planetary gear reducer is installed inside the flipping mechanism 410. Its input shaft is connected to the coupling of the flipping drive mechanism, and its output shaft is keyed to the connecting shaft. When the second servo motor drives the second reducer, it drives the connecting shaft to rotate through the coupling, thereby realizing a ±180° flipping motion of the flipping mechanism 410 around the horizontal axis. The flipping angle is monitored in real time by an absolute encoder and fed back to the control system for closed-loop control.

[0052] In this embodiment, the placement component 510 includes a first placement component 511 and a second placement component 512. The two ends of the first placement component 511 are connected to the connecting shafts of the first operating arm 312 and the second operating arm 313, respectively. The two ends of the second placement component 512 are also connected to the connecting shafts of the first operating arm 312 and the second operating arm 313, respectively. Positioning holes are provided at the top of both the first and second placement components 511 and 512. The ladder-shaped structure of the placement component 510 is formed by welding two parallel square steel beams and several equally spaced rectangular steel longitudinal beams, creating a uniformly distributed grid-like bearing surface. The two ends of the first placement component 511 and the second placement component 512 are hinged to the connecting shafts of the first operating arm 312 and the second operating arm 313 via spherical bearings, allowing for small-angle free swing to compensate for installation errors. The positioning holes at the top adopt a stepped hole design, with a hole diameter tolerance controlled at H7 grade and a depth tolerance of ±0.1mm, used for installing quick-positioning pins or clamping assemblies to achieve precise workpiece positioning.

[0053] In this embodiment, the connecting part 210 includes a slewing bearing 211 and a vibrator 212. The slewing bearing 211 is connected to the first operating arm 312, and the vibrator 212 is connected to the second operating arm 313. The slewing bearing 211 of the connecting part 210 is a crossed roller bearing, with its outer ring fixed to the first support seat by bolts and its inner ring rigidly connected to the flange of the first operating arm 312. The vibrator 212 adopts an eccentric block structure and is connected to the flange connecting shaft of the second operating arm 313 through a coupling. The excitation force can be adjusted by adjusting the angle of the eccentric block.

[0054] Furthermore, the slewing bearing 211 is made of a large-diameter, high-precision crossed roller bearing to ensure that the slewing mechanism 310 can achieve 360° continuous rotation. The first drive motor drives the slewing bearing 211 to rotate after being reduced in speed and increased in torque by the first reducer 612, so as to realize the rotation of the workpiece around the vertical axis.

[0055] In this embodiment, the three-axis positioner also includes a drive system, which comprises a rotary drive mechanism 610 and a tilting drive mechanism. The rotary drive mechanism 610 is connected to the slewing bearing 211, and the tilting drive mechanism is connected to the connecting shaft. The rated power of the first servo motor 611 of the rotary drive mechanism 610 is determined based on the load torque of the rotary mechanism 310, and is generally 3-7.5kW. It is equipped with an absolute encoder to achieve position feedback. The first reducer 612 is a planetary gear reducer with a reduction ratio of 1:30-1:50, and its output shaft is connected to the inner ring of the slewing bearing 211 via a spline. The rated power of the second servo motor of the tilting drive mechanism is 1.5-5kW. The second reducer is a worm gear reducer with a reduction ratio of 1:40-1:60. The coupling is a diaphragm coupling, with an allowable axial deviation of ±0.5mm and a radial deviation of ±0.2mm.

[0056] In this embodiment, the rotary drive mechanism 610 includes a first servo motor 611 and a first reducer 612, the first reducer 612 being connected to the first servo motor 611. The tilt drive mechanism includes a second servo motor, a second reducer, and a coupling, the second reducer being connected to the second servo motor, and the second reducer being connected to the connecting shaft via the coupling.

[0057] Furthermore, the rotary mechanism 310 uses a high-power AC first servo motor 611, paired with a high-precision planetary first reducer 612, selected according to the requirements of rotation speed and load torque, to ensure that the rotary mechanism 310 rotates smoothly and with high precision, and can achieve accurate angle positioning.

[0058] Furthermore, since the flipping mechanism 410 also has strict precision requirements and relatively small load, a combination of a medium-to-small power AC second servo motor and a second reducer is adopted. The output shaft of the second reducer is connected to the transmission component of the corresponding shaft through a key connection or coupling to meet different processing angle requirements and ensure the accuracy of flipping and tilting actions. When the second servo motor is driven, the placement part 510 can be flipped around the horizontal axis. The flipping angle range is generally from -180° to +180°.

[0059] Furthermore, the transmission of each shaft can employ gear transmission, synchronous belt transmission, or ball screw transmission, etc. Gear transmission transmits large torque, but requires good lubrication and precision assurance; synchronous belt transmission is smooth, has low noise, and can achieve transmission over a certain distance; ball screw transmission has extremely high precision.

[0060] In this embodiment, the support base 110 includes a first support base 112 and a second support base 111. The first support base 112 is located at the front of the second support base 111. The first support base 112 is connected to the slewing bearing 211, and the second support base is connected to the vibrator 212. Both the first support base 112 and the second support base 111 adopt a box-type welded structure with internal reinforcing ribs. The base plate is fixed to the ground by anchor bolts. The top of the first support base 112 is machined with a mounting surface that matches the outer ring of the slewing bearing 211. The side of the second support base 111 is provided with a vibrator 212 mounting bracket, which is connected to the vibrator 212 through a rubber buffer pad to absorb vibration energy.

[0061] In this embodiment, a first baffle 710 is provided at the top of the transmission arm 311, and a second baffle 810 is provided at the bottom of the transmission arm 311. The first baffle 710 at the top of the transmission arm 311 is made of steel plate and is fixed to the upper surface of the transmission arm 311 by bolts. The second baffle 810 at the bottom of the transmission arm 311 is also made of steel plate. The first baffle 710 at the top and the second baffle 810 at the bottom of the transmission arm 311 can protect and isolate foreign objects, and can also potentially enhance its structural strength and rigidity by connecting with the transmission arm 311, helping to resist load deformation, ensuring stable operation of the equipment and extending its service life.

[0062] This three-axis positioner further includes a control system, which comprises a controller, programming software, a human-machine interface (HMI), and a communication interface. The control system is connected to the controller, programming software, HMI, and communication interface. The controller uses a programmable logic controller (PLC) or a motion control card as its core controller. PLCs offer high reliability and ease of programming, making them suitable for industrial environments; motion control cards offer higher processing speed and accuracy, meeting complex motion trajectory control requirements. The programming software is equipped with corresponding software, allowing operators to input workpiece positioning commands through teach programming and offline programming. Teach programming is convenient and intuitive, recording key positions through manual operation of the positioner; offline programming relies on software to generate motion programs, suitable for mass production of complex workpieces. The HMI is a touchscreen display showing the positioner's real-time status, such as axis positions, speeds, and alarm information. Operators can set parameters, switch modes, and perform manual operations on it. The interface design aims for simplicity and clarity, facilitating quick learning for workers. The communication interface includes multiple interfaces, such as Ethernet and RS485, for data interaction with robots, processing equipment, and host computers to achieve automated linkage control.

[0063] In this embodiment, a T-shaped reinforcing rib is provided in the middle of the support base 110, and a base plate 113 is provided at the bottom of the support base 110. The T-shaped reinforcing rib in the middle of the support base 110 can enhance the structural strength and stability, distribute the load, and prevent deformation. The base plate 113 at the bottom increases the contact area, makes the placement stable, and provides an installation reference surface, which facilitates stable installation and improves the overall stability of the equipment.

[0064] Furthermore, the support base 110 and the base plate 113 are welded from high-strength cast iron or steel to provide stable support and have sufficient rigidity to resist deformation. The base plate 113 is usually designed with anchor bolt holes for easy fixing to the workshop floor.

[0065] Furthermore, a modular tooling fixture design concept is adopted, and various standard interfaces and connectors are developed to allow for quick replacement of fixture modules according to different workpiece shapes and sizes. For example, a universal T-slot support 110 is designed, which connects to different fixture plates via bolts to meet the clamping requirements of various workpieces.

[0066] Furthermore, pneumatic, hydraulic, or electric clamping devices can be introduced to achieve rapid clamping and release of workpieces. Taking pneumatic clamping as an example, the operation of the cylinder is controlled by a solenoid valve. The operator only needs to press a button to complete the workpiece clamping within seconds, improving production efficiency while ensuring uniform and stable clamping force to meet the workpiece fixation requirements during processing.

[0067] This utility model of a three-axis positioner, through its flexible multi-axis linkage structure, rotary and flipping mechanisms, high-precision stable positioning system, and optimized load-bearing design, achieves high motion flexibility during complex posture adjustments, meeting the multi-angle processing needs of complex-shaped workpieces; it realizes precise synchronous and coordinated multi-axis motion, ensuring long-term high-precision positioning and stable processing quality; it effectively improves the equipment's load capacity, enabling it to carry large and heavy workpieces, thus expanding its application range in the field of large workpiece processing.
