[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0021] Example: like Figure 1 , Figure 2 and Figure 11 As shown in the embodiment of this application, a positioner is disclosed, which has the advantages of strong versatility and high stability. It can efficiently realize the rotation and swing of large structural workpieces (especially box-type parts) during the welding process, and can adjust them to the ideal welding position, ensuring welding quality and efficiency. Its specific structure includes: a base frame 1, two drive boxes 2, a flipping bracket 3, a rotation drive mechanism 4, a driven support mechanism 5, two support bases 6, a displacement adjustment mechanism 7, and two end face brackets 8.

[0022] The base frame 1 is the base of the positioner, used to support other components and workpieces, and is fixed to the ground with anchor bolts and other parts during installation to ensure that the equipment is stable and does not shake during the flipping process.

[0023] Two drive boxes 2 are symmetrically installed at both ends of the base frame 1, and are used to install the power end and the driven end respectively. Their symmetrical arrangement ensures balanced force and enhances the overall structural stability.

[0024] The flipping bracket 3 is arranged between the two drive boxes 2 and is used to support the workpiece. The flipping bracket 3 includes a flipping frame 31 and end plates 32 disposed at both ends of the flipping frame 31. The end plates 32 are interfaces connected to the power end or the driven end.

[0025] For example, the flip frame 31 has a U-shaped structure and multiple reinforcing beams inside, which have extremely high bending and torsional stiffness and reduce the overall weight, thus achieving lightweighting.

[0026] The rotary drive mechanism 4 is mounted on a drive box 2 and is connected to an end plate 32 for transmission. It is used to provide rotational power and can drive the entire flipping bracket 3 and its components and workpieces to rotate and be positioned through the drive end plate 32.

[0027] The driven support mechanism 5 is installed on another drive box 2 and is rotatably connected to the other end plate 32. It is used to provide rotational support for the other end of the flipping bracket 3, thereby cooperating with the rotary drive mechanism 4 to form a stable two-point support. This reduces stress concentration, prevents the workpiece from shaking when flipping, and ensures welding accuracy.

[0028] The two support bases 6 are the bases for mounting the end face brackets 8. They are symmetrically arranged at both ends of the flip frame 31. One support base 6 is fixedly connected to the flip frame 31, and the other support base 6 is slidably connected to the flip frame 31. The design of fixing and sliding respectively can realize width adjustment, so as to adapt to workpieces of different sizes.

[0029] The displacement adjustment mechanism 7 is installed between the flip frame 31 and the sliding support base 6 to adjust the distance between the two support bases 6, enabling fast and precise distance adjustment.

[0030] Two end face supports 8 are detachably mounted on two support bases 6, and each end face support 8 includes a support plate 81 and a plurality of clamps 82 mounted on the support plate 81; the support plate 81 provides a large mounting surface, while the clamps 82 are used to clamp specific parts of the workpiece, such as: Figure 10 The bolts on the side of the gas holder are shown; in addition, the detachable design of the end face bracket 8 allows for quick replacement of the corresponding end face bracket 8 according to the shape and clamping position of different workpieces, thereby greatly improving the versatility of the equipment and making it adaptable to workpieces of different specifications.

[0031] The workflow of the above technical solution is as follows: First, the operator drives the sliding support base 6 to move on the flip frame 31 through the displacement adjustment mechanism 7 according to the length of the workpiece to be welded, thereby adjusting the distance between the two support bases 6 until it is slightly greater than the length of the workpiece, so as to leave space for the workpiece to be placed. Secondly, according to the clamping points at both ends of the workpiece, select the corresponding end face bracket 8, and then clamp and fix the clamps 82 on the end face bracket 8 to the corresponding clamping points one by one, so that the two end face brackets 8 are stably installed at both ends of the workpiece. Next, the workpiece and the end face brackets 8 installed at both ends are lifted together by hoisting equipment and moved above the two support bases 6. Then, the end face brackets 8 are connected and installed with the adjacent support bases 6 to ensure that the workpiece will not loosen or shift during the subsequent flipping movement. Finally, the operator controls the rotary drive mechanism 4 to start, which drives the end plate 32 on one side, thereby causing the entire flipping bracket 3, support base 6, end face bracket 8 and workpiece to rotate together, so as to adjust the first weld to be welded to the ideal position.

[0032] This invention achieves stable rotation and precise positioning of the workpiece through the flipping bracket 3 supported at both ends, effectively improving the stability and precision of welding. It also utilizes the adjustable support base 6 and the replaceable end face bracket 8 to achieve rapid adaptation to workpieces of various sizes and specifications, thereby enhancing the versatility of the device and shortening the adjustment time.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, the rotary drive mechanism 4 includes a gear ring 41, a reducer 42, a drive gear 43, and a motor 44, and its specific configuration is as follows: The gear ring 41 is rotatably connected to the side wall of the drive box 2, which can be achieved by a large slewing bearing, taking into account both load-bearing and rotation functions, and is fixedly connected to the corresponding end plate 32, so as to drive the entire flipping bracket 3 and the workpiece to rotate together. The reducer 42 is installed inside the drive housing 2, and its output shaft extends out of the drive housing 2. It can increase torque by reducing the speed, ensuring that the motor 44 can easily drive heavy workpieces. The drive gear 43 is fixedly sleeved on the output shaft of the reducer 42 and meshes with the gear ring 41. It is used to transmit the power output by the reducer 42 to the gear ring 41 so as to drive it to rotate. The motor 44 is installed inside the drive box 2 and is connected to the reducer 42 for transmission. It is the power source for the flipping action and can provide rotational motion. It is preferably a servo motor, so as to realize precise control of speed, stepless speed regulation and positioning control, and meet the position accuracy requirements in the welding process.

[0034] Through the above design, the high speed and low torque of motor 44 are transformed into the low speed and high torque required to drive heavy workpieces, thereby achieving smooth and precise flipping motion, effectively suppressing shaking during the welding process, ensuring welding accuracy and stability, and improving welding level and process quality.

[0035] Based on the above embodiments, such as Figure 3 As shown, the rotary drive mechanism 4 includes: The gear cover 45 is installed on the side wall of the drive housing 2 and surrounds the gear ring 41 and the drive gear 43.

[0036] The above design achieves the enclosure of the gear ring 41 and the drive gear 43, preventing foreign objects from the external environment from entering the gear transmission pair, preventing damage to the tooth surface, ensuring transmission smoothness, and extending service life.

[0037] In some embodiments, such as Figure 5 As shown, the driven support mechanism 5 includes a bearing plate 51, multiple rotating supports 52, a rotating shaft 53, and a flange 54, and its specific configuration is as follows: The bearing plate 51 is horizontally installed inside the drive box 2 to provide an installation surface and distribute the forces and torques received to the side walls of the drive box 2, thereby avoiding stress concentration and enhancing structural rigidity. Multiple rotating supports 52 are mounted on the bearing plate 51, which can suppress the vibration and radial runout that the rotating shaft 53 may generate through multi-point support; The rotating shaft 53 is rotatably sleeved in multiple rotating supports 52, and one end extends out of the drive box 2 to bear the radial gravity from the workpiece and the flipping bracket 3. The flange 54 is installed on the end of the rotating shaft 53 located outside the drive box 2 and is fixedly connected to the corresponding end plate 32. It has the advantages of reliable connection, high centering accuracy and easy disassembly and assembly.

[0038] The above design forms a distributed support that can effectively resist bending moments and radial forces generated by heavy loads. The flange 54 is used to achieve a precise and reliable connection, which can smoothly distribute the load and improve the structural rigidity and anti-sway capability of the passive end.

[0039] In some embodiments, such as Figure 7 As shown, it includes: Multiple linear guide rails 9 are arranged side by side between the flip frame 31 and the sliding support base 6, which can effectively support the overturning moment and complex loads, prevent the support base 6 from jamming or vibrating when moving, and ensure the smooth and stable adjustment process. In this embodiment, as Figure 7As shown, each linear guide rail 9 includes a slide rail 91 and a slider 92; wherein, the slide rail 91 is mounted on the flip frame 31, and the slider 92 is mounted on the slidable support base 6 and slides in cooperation with the slide rail 91; and multiple sliders 92 can be set to form a surface support, thereby ensuring the stability of the support.

[0040] The above design provides precise linear guidance and stable load-bearing for the sliding support base 6, ensuring that it can make smooth displacement adjustments on the flip frame 31 when bearing heavy loads, thus ensuring the reliability and stability of width adjustment.

[0041] In some embodiments, such as Figure 7 As shown, the displacement adjustment mechanism 7 includes: a rack 71, a torque amplifier 72, an adjusting gear 73, and a handwheel 74, and its specific configuration is as follows: The rack 71 is mounted on the flip frame 31 to convert rotational motion into linear displacement; The torque amplifier 72 is mounted on a sliding support base 6. It amplifies the output torque through an internal gear structure, so that the operator can still turn it with less force even under heavy load. The adjusting gear 73 is installed at the output end of the torque amplifier 72 and meshes with the rack 71 to pull the entire support base 6 to move. The handwheel 74 is installed at the input end of the torque amplifier 72, making it convenient for the operator to apply force.

[0042] Through the above design, the support base 6 can be precisely and stably linearly adjusted by manual operation with relatively little effort. Furthermore, the inherent self-locking characteristic of the torque amplifier 72 ensures that the position can be reliably locked after adjustment.

[0043] In some embodiments, such as Figure 8 and Figure 9 As shown, the end face bracket 8 also includes: a central shaft 83, multiple reinforcing ribs 84, and a limiting rod 85, the specific configuration of which is as follows: One end of the central shaft 83 is perpendicular to and fixedly connected to the side center of the support plate 81, and is used as a docking shaft that mates with the support base 6 to bear the axial force and bending moment of the workpiece. Multiple reinforcing ribs 84 are arranged around the outer periphery of the central shaft 83 and connected to the support plate 81 to enhance local rigidity and distribute load, thereby improving the bending and torsional stiffness of the region. The limiting rod 85 passes through the other end of the central shaft 83 and is perpendicular to the central shaft 83, thus forming a "T"-shaped structure to prevent the end face bracket 8 from rotating relative to the support base 6.

[0044] The support base 6 has a positioning groove 601 on its top that is adapted to the central shaft 83. This groove is used to cooperate with the central shaft 83 to achieve automatic centering of the end face bracket 8, ensuring that the center position of the end face bracket 8 is fixed and guaranteeing repeatability accuracy. The positioning groove 601 has a limiting groove 602 on both sides that is adapted to the limiting rod 85. This groove accommodates the limiting rod 85 and provides anti-torsional support for the limiting rod 85 to transmit torque to the support base 6. The support base 6 also has a locking assembly 10 on both sides that can lock the limiting rod 85. The locking assembly 10 can press the limiting rod 85 into the limiting groove 602 to prevent the end face bracket 8 from loosening and falling off during equipment operation.

[0045] Through the above design, the end face bracket 8 can be quickly centered and accurately positioned, effectively resisting torsional torque, ensuring the stability of the connection, improving rigidity and load-bearing capacity, and enabling quick replacement of the end face bracket 8. This ensures repeatability and overall connection rigidity, and improves the stability and efficiency of welding operations.

[0046] Based on the above embodiments, such as Figure 8 As shown, the support base 6 includes: a base plate 61, a vertical plate 62, two side plates 63, and a top block 64, and its specific configuration is as follows: The base plate 61 serves as the mounting surface, which can distribute the pressure evenly, thereby ensuring a stable connection. Furthermore, a hollow opening can be made in its center to reduce weight. The upright plate 62 is vertically installed on the base plate 61 to receive the weight of the workpiece transmitted from the top block 64 and transmit it downward to the base plate 61. Two side plates 63 are installed side by side and spaced between the upright plate 62 and the bottom plate 61 to support the upright plate 62, prevent it from bending under pressure, and form a semi-enclosed box structure, which can effectively resist torque and improve lateral stability. The top block 64 is installed on the top of the vertical plate 62 and the side plate 63 to bear the stress generated when the fixture is clamped and the workpiece shakes. A hollow opening can also be opened in its center to play a role in weight reduction. The top surface of the top block 64 is provided with a positioning groove 601 and a limiting groove 602, which takes into account both lightweight and structural stability.

[0047] Through the above design, the load can be evenly distributed and stably transferred to the flipping frame 31, effectively suppressing the shaking during the welding process, ensuring the stability of the support, and reducing the weight while ensuring the overall structural stability, thus achieving lightweighting.

[0048] In some embodiments, such as Figure 6 As shown, the flip bracket 3 includes: Four reinforcing plates 33 are respectively located on both sides of the end of the flip frame 31, and the reinforcing plates 33 are fixedly connected to the adjacent end plates 32.

[0049] The above design forms a triangular support structure, which enhances the structural stability of the connection between the flip frame 31 and the end plate 32, effectively resists bending moment and shear stress, prevents deformation at the connection, ensures stable power transmission, and improves the reliability of long-term equipment operation.
