[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1 and Figure 2 As shown, the present invention provides a welding positioning device, which includes a displacement mechanism 10, a clamping mechanism 20 and an end mechanism 30. The displacement mechanism 10 includes a rotating part 11, a translation component 12 and a clamping component 13. The rotating part 11 is drivingly connected to the translation component 12. The rotation axis of the rotating part 11 extends along a first direction. The clamping component 13 is arranged on the translation component 12. The translation component 12 can drive the clamping component 13 to move in a vertical plane. The clamping component 13 is used to clamp one end of the material 01 to be welded. The first direction is perpendicular to the vertical plane. Along the first direction (i.e. Figure 1 The clamping mechanism 20 and the displacement mechanism 10 are spaced apart. The clamping mechanism 20 is used to clamp the middle of the material 01 to be welded and limit the displacement of the material 01 to be welded in the vertical plane. The material 01 to be welded can rotate relative to the clamping mechanism 20. Figure 1 The end mechanism 30 is spaced apart from the clamping mechanism 20, and the end mechanism 30 is used to abut and position the other end of the material to be welded 01. Specifically, in this embodiment, the material to be welded 01 is the main beam of the heliostat, and the main beam of the heliostat is a circular tubular structure. Of course, in other embodiments, the material to be welded 01 may also be other components that can be applied to the welding positioning device of the present invention.

[0049] According to the technical solution of the present invention, the welding positioning device is composed of a displacement mechanism 10, a clamping mechanism 20 and an end mechanism 30, which are arranged in sequence along the first direction to achieve the clamping and displacement of the material 01 to be welded. Among them, the displacement mechanism 10 includes a rotating part 11, a translation assembly 12 and a clamping assembly 13. The clamping assembly 13 is arranged on the translation assembly 12. When it is necessary to clamp the material 01 to be welded by the clamping assembly 13, the position of the clamping assembly 13 in the vertical plane direction can be adjusted by the translation assembly 12 according to the clamping position required by the material 01 to be welded. The rotating part 11 is drivingly connected to the translation assembly 12, and the rotation axis of the rotating part 11 extends along the first direction, so that the material 01 to be welded after clamping can be rotated around the axis direction to adapt to different welding points. The clamping mechanism 20 and the displacement mechanism 10 are arranged at intervals. The clamping mechanism 20 is used to clamp the middle part of the material 01 to be welded and limit the displacement of the material 01 to be welded in the vertical plane. The material 01 to be welded can rotate relative to the clamping mechanism 20. The above structure can ensure that the material 01 to be welded can remain stable and prevent displacement caused by external interference or its own gravity. The end mechanism 30 is located on the other side of the clamping mechanism 20 along the first direction, and is used to abut against the other end of the material 01 to be welded. The above structure can clamp the material 01 to be welded, and the displacement mechanism 10 can adaptively adjust its position according to the bending degree of the material 01 to be welded to clamp the material 01 to be welded, thereby improving the overall welding efficiency and welding effect of the device.

[0050] During the operation, the material 01 to be welded is loaded onto the welding positioning device, and the material 01 to be welded is first clamped by the end mechanism 30 and the clamping mechanism 20. When the clamping assembly 13 of the displacement mechanism 10 clamps the material 01 to be welded, the end mechanism 30 is released and returned to its original position, and the displacement mechanism 10 cooperates with the clamping mechanism 20 to perform rotation welding on the material 01 to be welded, and the clamping mechanism 20 clamps the middle of the material 01 to ensure the stability of the material 01 to be welded during welding. After welding is completed, the displacement mechanism 10 and the clamping mechanism 20 are released to complete the entire process.

[0051] like Figure 5 and Figure 6As shown, the translation assembly 12 includes a first mounting portion 121 and a first guide rail 122. The rotating portion 11 is drivingly connected to the first mounting portion 121. The first guide rail 122 extends along the second direction, and the first guide rail 122 is arranged on a side of the first mounting portion 121 away from the rotating portion 11. The clamping assembly 13 is movably arranged on the first guide rail 122, and the clamping assembly 13 can move in the second direction relative to the first mounting portion 121. In this embodiment, the rotating portion 11 is drivingly connected to the first mounting portion 121, so that the first mounting portion 121 can rotate 360° around the first direction. The first guide rail 122 is arranged on the first mounting portion 121, and the first guide rail 122 extends along the second direction. The first guide rail 122 is used to provide a moving path for the clamping assembly 13 in the second direction.

[0052] Specifically, the material of the first guide rail 122 can be selected to have good wear resistance and high strength, such as cemented carbide or hardened steel, to ensure accuracy and stability in long-term use.

[0053] Further, the translation assembly 12 further includes a second mounting portion 123 and a second guide rail 124. The second mounting portion 123 is movably disposed on the first guide rail 122. The second guide rail 124 extends along a third direction, and the second guide rail 124 is disposed on a side of the second mounting portion 123 away from the first mounting portion 121. The clamping assembly 13 is movably disposed on the second guide rail 124, and the clamping assembly 13 moves relative to the first mounting portion 121 via the second mounting portion 123, and the third direction has an angle with the second direction.

[0054] In this embodiment, the second mounting portion 123 is movably disposed on the first guide rail 122, and the second guide rail 124 is disposed on a side of the second mounting portion 123 away from the first mounting portion 121. The extension direction of the second guide rail 124 (i.e., the third direction) is not parallel to the extension direction of the first guide rail 122 (i.e., the second direction), but forms a non-zero angle. This design allows the clamping assembly 13 to move not only in the second direction, but also to be further adjusted in the third direction. This dual-degree-of-freedom movement capability ensures that the clamping assembly 13 can be accurately positioned at different positions of the welded material 01, increases the tolerance for the linearity of the welded material 01, and improves the flexibility and adaptability of the device.

[0055] Specifically, the second mounting portion 123 is provided with a slider or a pulley adapted to the first guide rail 122 on a side close to the first mounting portion 121 , so as to ensure smooth movement of the second mounting portion 123 on the first guide rail 122 .

[0056] Furthermore, the translation assembly 12 also includes a limiting structure 125, which is arranged between the first mounting portion 121 and the second mounting portion 123 and between the second mounting portion 123 and the clamping assembly 13, and the limiting structure 125 is used to limit the displacement of the second mounting portion 123 relative to the first mounting portion 121, and the displacement of the clamping assembly 13 relative to the second mounting portion 123.

[0057] In this embodiment, a limiting structure 125 is provided between the first mounting portion 121 and the second mounting portion 123, and between the second mounting portion 123 and the clamping assembly 13. When the second mounting portion 123 moves in the second direction along the first guide rail 122, the limiting structure 125 prevents it from exceeding a predetermined maximum displacement. Similarly, when the clamping assembly 13 moves in the third direction along the second guide rail 124, the limiting structure 125 between the clamping assembly 13 and the second mounting portion 123 limits its displacement, ensuring that the clamping assembly 13 works within a correct range.

[0058] Specifically, the limiting structure 125 should be designed as a device that can accurately adjust the displacement to adapt to the welding materials 01 of different lengths and shapes. The limiting structure 125 can take a variety of forms, such as a mechanical limit block, an electronic limit switch or a magnetic limit sensor, among which an L-shaped limit block is used in this embodiment.

[0059] like Figure 5 As shown, the clamping assembly 13 includes a first base 131, a first driving member 133 and a clamping portion 134. The first base 131 is movably arranged on the second guide rail 124, and two mounting seats 132 are arranged on the first base 131. The two mounting seats 132 are located on a side of the first base 131 away from the second guide rail 124, and the two mounting seats 132 are arranged relatively spaced apart. A first driving member 133 is arranged on each mounting seat 132. The driving end of each first driving member 133 is provided with a clamping portion 134, and the two first driving members 133 are used to drive the two clamping portions 134 to move closer to or away from each other.

[0060] In this embodiment, the first base 131 is configured as a movable structure, which can reciprocate along the third direction on the second guide rail 124. Two mounting seats 132 are provided on the first base 131. The two mounting seats 132 are respectively located on the side of the first base 131 away from the second guide rail 124, and are arranged at intervals corresponding to each other. The function of the mounting seat 132 is to fix the first driving member 133 to ensure the stability and precision of the first driving member 133. Since a certain interval is maintained between the two mounting seats 132, the two first driving members 133 can respectively drive the clamping part 134 from both sides of the material 01 to clamp the material 01 to be welded, thereby providing better stability. The first driving member 133 is connected to the clamping part 134 through its driving end. When the first driving member 133 is extended or retracted, the clamping part 134 will be closer to or farther away from the material 01 to be welded accordingly.

[0061] Specifically, a slider or a pulley adapted to the second guide rail 124 is fixedly provided on one side of the first base 131 close to the second mounting portion 123 to ensure smooth movement on the second guide rail 124 .

[0062] Specifically, the first driving member 133 can be a cylinder, an electric cylinder or other forms of linear drive, which is characterized by being able to provide sufficient pressure to ensure that the welded material 01 is firmly clamped, while also having precise control capabilities so that the clamping process can be carried out gently to avoid damage to the material.

[0063] Specifically, the clamping part 134 can be an adaptive clamp with a V-shaped groove, a concave clamping block or an adjustable clamping jaw, etc., which can adapt to materials of different diameters or shapes. The two clamping parts 134 move relative to each other under the drive of the first driving member 133. When they are close to each other, the welded material 01 is clamped; when they are far away from each other, the welded material 01 is released.

[0064] like Figure 4 As shown, the clamping mechanism 20 includes a second base 21, a buckling portion 22, a second driving member 23 and a damping roller 24. The top of the second base 21 has a receiving notch. The buckling portion 22 can be movably arranged on the top of the second base 21, and the buckling portion 22 has a clamping position and an escape position that are relatively arranged. When the buckling portion 22 is in the clamping position, the buckling portion 22 cooperates with the receiving notch to form a receiving space to accommodate the welded material 01. The second driving member 23 is drivingly connected to the buckling portion 22, and the second driving member 23 drives the buckling portion 22 to move between the clamping position and the escape position. The damping roller 24 is rotatably arranged on the second base 21 and the buckling portion 22. The damping roller 24 is used to abut against the welded material 01. When the welded material 01 rotates, it can drive the damping roller 24 to rotate.

[0065] In this embodiment, the top of the second base 21 is designed with a receiving notch, and the shape and size are customized according to the specific requirements of the material 01 to be welded. The buckle part 22 is movably mounted on the top of the second base 21, and the buckle part 22 is driven by the second driving member 23 to switch between the clamping position and the avoidance position. The design shape of the buckle part 22 can be closely matched with the receiving notch of the second base 21 to form a receiving space to ensure the stability and positioning accuracy of the material 01 to be welded. When in the avoidance position, the buckle part 22 will be moved away from the top of the material 01 to be welded, which is convenient for the loading and unloading operations of the material 01 to be welded. The function of the receiving notch is to cooperate with the buckle part 22 when the buckle part 22 moves to the clamping position to form a precise receiving space for receiving and fixing the middle part of the material 01 to be welded. The second driving member 23 is connected to the buckle part 22 for driving and accurately controlling the movement of the buckle part 22. Through the second driving member 23, the buckling portion 22 can smoothly move from the avoidance position to the clamping position to ensure accurate clamping of the material 01 to be welded. At the same time, the second driving member 23 can also provide sufficient force so that the buckling portion 22 can tightly buckle the material to prevent it from being displaced during the welding process. Damping rollers 24 are provided on the second base 21 and the buckling portion 22 to reduce the vibration and displacement of the material 01 to be welded during the welding process. At the same time, each damping roller 24 can rotate along the roller axis, so that the material 01 to be welded can rotate with the displacement mechanism 10 in the clamped state. When the material 01 to be welded rotates, the damping roller 24 contacts the surface of the material, absorbs the rotational force of the material 01 to be welded through the rotation of the damping roller 24, and provides a certain damping effect to reduce the vibration of the material during the rotation process.

[0066] Specifically, the damping roller 24 is usually designed to use a material with high elasticity and low friction coefficient, such as polyurethane or Teflon, to ensure that the rotation smoothness of the material is not affected while providing damping.

[0067] like Figure 1 and Figure 4 As shown, the welding positioning device includes two clamping mechanisms 20, and the two clamping mechanisms 20 are spaced apart along the first direction. In this embodiment, the two clamping mechanisms 20 are spaced apart along the first direction by a certain distance, which ensures the stable clamping of the welded material 01 in the length direction and avoids deformation or displacement problems caused by single-point clamping.

[0068] Furthermore, the welding positioning device further comprises a positioning mechanism 40, and the positioning mechanism 40 is used to limit the position of the material to be welded 01 on the vertical plane and / or to limit the position of the material to be welded 01 in the first direction.

[0069] In this embodiment, the positioning mechanism 40 can be arranged between the two clamping mechanisms 20 to limit the limiting ring 02 arranged on the welded material 01 in the axial direction to prevent the welded material 01 from excessive displacement when the end mechanism 30 abuts against the welded material 01.

[0070] Specifically, the positioning mechanism 40 is usually composed of one or more positioning pins and positioning blocks, and these components can be fixed or adjustable to adapt to different types of welded materials 01.

[0071] Further, the positioning mechanism 40 includes a lifting seat 41 and a third driving member 43. The lifting seat 41 is provided with a plurality of limiting posts 42, which are arranged at intervals on both sides of the welded material 01 along the second direction, and the first direction and the second direction are perpendicular to each other. The third driving member 43 is drivingly connected to the lifting seat 41, and the third driving member 43 is used to drive the lifting seat 41 to rise and fall.

[0072] In this embodiment, the positioning mechanism 40 is composed of a lifting seat 41 and a third driving member 43. A plurality of limiting columns 42 are provided on the lifting seat 41, and the limiting columns 42 are arranged at intervals along the second direction. The limiting columns 42 are used to provide stable contact points on both sides of the material 01 to be welded, so as to ensure that the material 01 to be welded can be accurately aligned after being placed on the welding positioning device. The third driving member 43 is used to drive the lifting seat 41 to rise and fall vertically.

[0073] In the specific working process, a plurality of limit posts can be set as stop posts and drive posts according to the requirements of the material 01 to be welded. The stop post can cooperate with the limit ring 02 on the material 01 to be welded to limit the axial direction of the material 01 to be welded. The drive post abuts against the bracket 03 on the material 01 to be welded (or the drive post can also abut against the welding plate or other suitable components on the material 01 to be welded that protrudes from the surface of the material 01 to be welded), and is lifted and lowered by the driving action of the third drive member 43 to achieve the rotation effect on the whole material 01 to be welded. In this embodiment, the length of the limit post 42 is fixed. When the third drive member 43 drives the limit post 42 to rise to a preset height, the material 01 to be welded is just in the initial welding position. After the clamping mechanism 20 is clamped, the third drive member 43 drives the lifting seat 41 to descend and retract, so that the displacement mechanism 10 can smoothly rotate the material 01 to be welded according to the specified rotation angle.

[0074] Specifically, a plurality of third driving members 43 may be provided, and the plurality of third driving members 43 are drivingly connected to the plurality of limiting columns 42 in a one-to-one correspondence, so as to improve the limiting capacity and adaptability of the limiting columns 42 to different welding materials 01 .

[0075] Specifically, the shape and size of the lifting seat 41 should be designed according to the maximum size and weight of the welded material 01 to ensure sufficient load-bearing capacity and stability. Generally, the lifting seat 41 is made of high-strength materials, such as steel or aluminum alloy, to withstand the pressure and heat during welding.

[0076] Specifically, the third driving member 43 can be a cylinder, a hydraulic cylinder, a screw mechanism or an electric push rod, etc. The specific selection is determined according to factors such as the accuracy requirements, load capacity and working environment of the equipment.

[0077] like Figure 3 As shown, the end mechanism 30 includes a fourth driving member 31 and a limiting plate 32. The driving end of the fourth driving member 31 can move along the first direction. The limiting plate 32 is arranged on the driving end, and the limiting plate 32 is used to abut against the end of the welded material 01 to limit the displacement of the welded material 01 in the first direction.

[0078] In this embodiment, the fourth driving member 31 is drivingly connected to the limiting plate 32. The limiting plate 32 is arranged at the driving end of the fourth driving member 31 so that the limiting plate 32 abuts against one end of the welded material 01. The driving end of the fourth driving member 31 is designed to be movable along the first direction.

[0079] Specifically, the selection of the fourth driving member 31 needs to take into account its thrust, stroke and accuracy to meet the requirements of stability and positioning accuracy of the end of the welded material 01.

[0080] like Figure 2 As shown, the welding positioning device further includes a first frame 50 and a second frame 51. The first frame 50 extends along a first direction, and the displacement mechanism 10 and the clamping mechanism 20 are both arranged on the first frame 50. The second frame 51 is spaced apart from the first frame 50, and the end mechanism 30 is arranged on the second frame 51.

[0081] In this embodiment, the first frame 50 extends along the first direction, providing a stable support platform for installing and carrying the displacement mechanism 10 and the clamping mechanism 20. Its length and width should be designed according to the size and weight of the material 01 to be welded, ensuring sufficient support area and load-bearing capacity. The second frame 51 is arranged on the side of the first frame 50, and is spaced a certain distance from the first frame 50 to ensure that both ends of the material 01 to be welded can be supported and positioned to prevent bending or vibration during the welding process. The second frame 51 also extends along the first direction to provide sufficient support. The end mechanism 30 is arranged on the second frame 51, and is used to abut the other end of the material 01 to be welded to achieve the end positioning of the material 01 to be welded. Since the first frame 50 and the second frame 51 are arranged separately, the material 01 to be welded of any length can be clamped by adjusting the distance between the two frames, thereby improving the overall applicability and flexibility of the device.

[0082] Specifically, the first frame 50 and the second frame 51 may be welded steel frames having sufficient strength and rigidity to resist stress and deformation during welding.

[0083] In a specific embodiment, the first frame 50 may also be provided with a guide rail and a driving mechanism to facilitate the installation and adjustment of the displacement mechanism 10 and the clamping mechanism 20, ensuring that they can accurately perform the predetermined movement and clamping operations.
