[0021] Reference Figure 1 to Figure 6The present embodiment proposes a welding device for trailer production, wherein the trailer has two transverse main beams 1 and a plurality of W-shaped through beams 2, wherein the W-shaped through beam 2 has a W-shaped longitudinal section and an I-shaped cross section, wherein the main beam 1 has an I-shaped opening 101, wherein the W-shaped through beam 2 passes through the I-shaped opening 101 to penetrate the main beam 1, wherein the W-shaped through beam 2 comprises a first upper transverse portion 201, a first lower transverse portion 202, a second upper transverse portion 203, a second lower transverse portion 204 and a third upper transverse portion 205 which are arranged in sequence, wherein the first lower transverse portion 202 is used to be located in the I-shaped opening 101 of one main beam 1, and the second lower transverse portion 204 is used to be located in the I-shaped opening 101 of another main beam 1, wherein the first upper transverse portion 201 is used to be located in the I-shaped opening 101 of the second main beam 1, wherein the first lower transverse portion 202 is used to be located in the I-shaped opening 101 of the second main beam 1, wherein the first upper transverse portion 201 ... The lowering seat 3 and the second lifting seat 4, the first lifting seat 3 and the second lifting seat 4 are respectively arranged below the two main beams 1, and are used to lift the two main beams 1 respectively; the longitudinal moving member 5 is arranged above the main beam 1 for longitudinal relative movement; the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 are all hinged on the longitudinal moving member 5 at the upper ends; the first clamping member 9, the second clamping member 10 and the third clamping member 11 are respectively arranged at the lower end of the first telescopic member 6, the lower end of the second telescopic member 7 and the lower end of the third telescopic member 8, and correspond to the first upper transverse portion 201, the second upper transverse portion 203 and the third upper transverse portion 205 respectively, and are used to clamp the first upper transverse portion 201, the second upper transverse portion 203 and the third upper transverse portion 205 respectively.

[0022] In this embodiment, the first lifting seat 3 and the second lifting seat 4 are respectively arranged under the two main beams 1. The design principle is to lift the two main beams 1 respectively through the lifting function of the first lifting seat 3 and the second lifting seat 4, so as to adjust the height position of the main beam 1 and provide suitable space for the subsequent installation of the W-shaped through beam 2. The technical effect is that it can accurately control the height of the main beam 1, so that the I-shaped opening 101 of the main beam 1 is better aligned with the W-shaped through beam 2, and the accuracy and efficiency of the installation are improved. At the same time, the use of the lifting seat reduces the workload of manually adjusting the height of the main beam and improves the degree of automation of production.

[0023] In this embodiment, the longitudinal moving member 5 is arranged above the main beam 1 for longitudinal relative movement. The design principle is to utilize the moving function of the longitudinal moving member 5 to adjust its position in the longitudinal direction so as to match the installation position of the W-shaped through-beam 2. The technical effect is that it can flexibly adjust its position according to different installation requirements, provide a stable installation foundation for the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8, and ensure that they can accurately clamp the corresponding parts of the W-shaped through-beam 2.

[0024] In this embodiment, the upper ends of the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 are hinged on the longitudinal movable member 5. The design principle is that through the telescopic function, its length can be adjusted to adapt to W-shaped through-beams 2 of different sizes. The hinged design enables the telescopic members to adjust the angles more flexibly during operation, thereby improving the accuracy and stability of clamping. The technical effect is that they can accurately adjust their own length and angle according to the height and position of the W-shaped through-beam 2, so as to achieve the separate adjustment of the positions of the first clamp 9, the second clamp 10 and the third clamp 11. At the same time, the use of telescopic members improves the adaptability of the equipment and can meet the production needs of trailers of different specifications.

[0025] In this embodiment, the first clamp 9, the second clamp 10 and the third clamp 11 are respectively arranged at the lower end of the first telescopic member 6, the lower end of the second telescopic member 7 and the lower end of the third telescopic member 8, and correspond to the first upper cross section 201, the second upper cross section 203 and the third upper cross section 205 respectively. The design principle is that through the design of the clamp, the corresponding part of the W-shaped through-beam 2 can be firmly clamped for installation operation. The technical effect is that they can accurately clamp the specific part of the W-shaped through-beam 2, ensure that the first clamp 9, the second clamp 10 and the third clamp 11 can accurately clamp the W-shaped through-beam 2, and control the continuous adjustment angle of the W-shaped through-beam 2 to be inserted into the I-shaped opening 101 of the main beam 1, thereby completing the automatic insertion of the W-shaped through-beam 2 into the main beam 1, thereby solving the technical problem that the W-shaped through-beam is inserted into the I-shaped opening 101 of the main beam 1 in the prior art and the manual operation efficiency is very low, and the stability and accuracy of the W-shaped through-beam 2 during the installation process.

[0026] In this embodiment, although the I-shaped opening 101 of the main beam 1 has a certain margin, which can make the W-shaped through-beam 2 swing in the I-shaped opening 101, the key to insertion is that the W-shaped through-beam 2 needs to be inserted into two I-shaped openings 101, rather than one I-shaped opening 101. Assuming that the W-shaped through-beam 2 is adjusted to a straight line, it will become simple to insert the two I-shaped openings 101, but the overall structural strength will decrease. Adjusting to a W-shaped through-beam 2 can greatly improve the structural strength of the trailer frame, but it will face the problem of difficulty in inserting the I-shaped opening 101 of the main beam 1. In this embodiment, the first lifting seat 3 and the second lifting seat 4 are designed to lift and jack the two main beams 1 to adjust the height and height difference of the two I-shaped openings 101, and the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 are used to lift and adjust the height and angle of the W-shaped through-beam 2, so that the W-shaped through-beam 2 can be automatically inserted into the two I-shaped openings 101, thereby greatly improving the welding preparation efficiency. It should be noted that the first clamp 9, the second clamp 10 and the third clamp 11 do not clamp the W-shaped through-beam 2 at the same time, but two of them are selected to clamp the W-shaped through-beam 2 according to the stage when the W-shaped through-beam 2 is inserted into the two I-shaped openings 101. For example, when the W-shaped through-beam 2 is about to be inserted into the second I-shaped opening 101, the first clamp 9 and the third clamp 11 need to keep clamping the W-shaped through-beam 2, and the second clamp 10 needs to cancel clamping the W-shaped through-beam 2 to avoid interference between the second clamp 10 and the second main beam 1.

[0027] In this embodiment, an operating table can be set to support the entire equipment to ensure stable operation of the equipment. The first lifting seat 3 and the second lifting seat 4 can accurately adjust the height of the main beam, the longitudinal moving member 5 provides a stable foundation and flexible position adjustment, and the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 cooperate with the clamp to accurately clamp the W-shaped through beam 2. These components work together to make the trailer production process more efficient and stable, and the produced trailer frame structure is more accurate and reliable. Through the coordination of various components, the technical problems of low efficiency of inserting the W-shaped through beam 2 into the main beam 1 and low overall welding efficiency caused by manual installation and assembly in trailer production are effectively solved. The first lifting seat 3 and the second lifting seat 4 improve the adjustment accuracy of the main beam position, the longitudinal moving member 5 and the telescopic member improve the installation flexibility, and the clamp ensures accurate clamping, which reduces manual operation as a whole, realizes high-quality and efficient assembly of the trailer frame, and meets the needs of trailer production.

[0028] Furthermore, it also includes a transverse moving member 12 , which moves transversely above the main beam 1 , and the longitudinal moving member 5 is arranged on the transverse moving member 12 for longitudinal movement.

[0029] In the present embodiment, the lateral moving member 12 is laterally moved above the main beam 1, and the longitudinal moving member 5 is longitudinally moved and arranged on the lateral moving member 12. The design principle of the lateral moving member 12 is to adjust the position of the longitudinal moving member 5 in the lateral direction through its lateral moving function, so as to realize the overall lateral position adjustment of the first telescopic member 6, the second telescopic member 7, the third telescopic member 8 and the corresponding clamping member. The technical effect of the lateral moving member 12 is to further enhance the flexibility and adaptability of the equipment, and can realize the completion of inserting a W-shaped through beam 2 into the main beam 1, and automatically realize the insertion of the second and subsequent W-shaped through beams 2 into the main beam 1. It can accurately adjust the lateral position of the longitudinal moving member 5 according to the different trailer sizes and the installation position requirements of the W-shaped through beam 2, so that the clamping member can more accurately align with the corresponding part of the W-shaped through beam 2 for clamping operation. At the same time, the cooperation of the lateral moving member 12 and the longitudinal moving member 5 enables the equipment to flexibly adjust the position in a two-dimensional plane, greatly improving the efficiency and accuracy of installation.

[0030] The technical problem solved by the lateral moving member 12 in cooperation with other components is that, in trailer production, the problem that only relying on the longitudinal moving member 5 cannot meet the installation requirements of different lateral positions is solved. Through the cooperation of the lateral moving member 12 and the longitudinal moving member 5, the all-round position adjustment of the W-shaped through-beam 2 is realized, the accuracy and efficiency of the W-shaped through-beam 2 inserted into the main beam 1 are improved, the workload of manual adjustment is reduced, and the technical problems of low efficiency of inserting the W-shaped through-beam 2 into the main beam 1 and low overall welding efficiency caused by manual operation and installation are effectively solved.

[0031] Furthermore, it also includes a first rotating clamp 13, a second rotating clamp 14 and a third rotating clamp 15, which are rotatably arranged on the first clamp 9, the second clamp 10 and the third clamp 11 respectively, and are used to clamp the first upper cross portion 201, the second upper cross portion 203 and the third upper cross portion 205 respectively, and are used to clamp the W-shaped through-beam 2 to pass through the two I-shaped openings 101 in sequence under the longitudinal movement of the longitudinal moving member 5.

[0032] In this embodiment, the first rotating clamp 13, the second rotating clamp 14 and the third rotating clamp 15 are rotatably arranged on the first clamp 9, the second clamp 10 and the third clamp 11 respectively. The design principle is that by arranging a rotatable clamp on the clamp, when clamping the corresponding part of the W-shaped through-beam 2, the angle can be flexibly adjusted according to the installation requirements, so as to better adapt to the process of inserting the W-shaped through-beam 2 into the I-shaped opening 101 of the main beam 1. The technical effect is that the first rotating clamp 13, the second rotating clamp 14 and the third rotating clamp 15 can clamp the corresponding part of the W-shaped through-beam 2 more firmly, and driven by the longitudinal movement of the longitudinal moving member 5, the moving direction and angle of the W-shaped through-beam 2 can be accurately controlled, so that it can pass through the two I-shaped openings 101 in sequence, thereby improving the accuracy and efficiency of the installation. At the same time, the design of the rotating clamp increases the flexibility of clamping, can better adapt to W-shaped through-beams 2 of different shapes and sizes, and improves the adaptability of the equipment.

[0033] The technical problem solved in cooperation with other components is to further solve the problem of low efficiency of inserting the W-shaped through-beam 2 into the main beam 1. By cooperating with the first clamp 9, the second clamp 10, the third clamp 11 and the longitudinal moving member 5, more precise control and operation of the W-shaped through-beam 2 is achieved, manual intervention is reduced, and welding preparation efficiency is improved, effectively solving the technical problem of low overall welding efficiency caused by manual operation, installation and assembly.

[0034] Furthermore, the second rotating clamping portion 14 is movably and rotatably disposed on the second clamping member 10 , and the third rotating clamping portion 15 is movably and rotatably disposed on the third clamping member 11 .

[0035] In this embodiment, the second rotating clamp 14 is movably and rotatably arranged on the second clamp 10, and the third rotating clamp 15 is movably and rotatably arranged on the third clamp 11. The design principle is that by making the second rotating clamp 14 and the third rotating clamp 15 both movable and rotatable, the flexibility and adaptability of clamping the corresponding parts of the W-shaped through-beam 2 are increased, and the W-shaped through-beam 2 is well avoided from being stuck in the I-shaped opening 101 of the main beam 1. During the installation process, the position and angle of the clamp can be adjusted according to different installation requirements to better cooperate with the W-shaped through-beam 2 to be inserted into the I-shaped opening 101 of the main beam 1. The technical effect is that this design enables the second rotating clamp 14 and the third rotating clamp 15 to more accurately control the second upper cross section 203 and the third upper cross section 205 of the W-shaped through-beam 2, and the position and angle can be fine-tuned according to actual conditions during the insertion process, thereby improving the accuracy and stability of the installation. At the same time, the functions of movement and rotation enable the clamp to better adapt to W-shaped through-beams 2 of different sizes and shapes, thereby improving the versatility of the equipment. The technical problem solved in cooperation with other components is to further solve the complexity of the process of inserting the W-shaped through-beam 2 into the main beam 1. During the installation process, due to the special shape of the W-shaped through-beam 2, precise control and adjustment are required. The movement and rotation functions of the second rotating clamp 14 and the third rotating clamp 15, in cooperation with other components, reduce the difficulty and uncertainty of manual operation, improve welding efficiency, and effectively solve the technical problem of low overall welding efficiency caused by manual operation installation and assembly.

[0036] Furthermore, the second clamp 10 and the third clamp 11 both have an arc groove 16 , the second rotating clamp 14 is rotatably and slidably disposed in the arc groove 16 of the second clamp 10 , and the third rotating clamp 15 is rotatably and slidably disposed in the arc groove 16 of the third clamp 11 .

[0037] In this embodiment, the second clamp 10 and the third clamp 11 both have an arc groove 16, the second rotating clamp 14 is rotatably and slidably arranged in the arc groove 16 of the second clamp 10, and the third rotating clamp 15 is rotatably and slidably arranged in the arc groove 16 of the third clamp 11. The design principle is to use the shape characteristics of the arc groove 16 to provide a specific motion trajectory for the second rotating clamp 14 and the third rotating clamp 15. The combined design of rotation and sliding enables the clamp to be more flexibly adjusted in the arc groove 16 to adapt to the W-shaped through-beam 2 of different angles and positions. The technical effect is that the setting of the arc groove 16 makes the movement of the second rotating clamp 14 and the third rotating clamp 15 more orderly and precise. In the process of clamping the W-shaped through-beam 2, the clamp can rotate and slide in the arc groove 16 according to the actual situation, so as to better adjust the angle and position, and ensure that the W-shaped through-beam 2 can be accurately inserted into the I-shaped opening 101 of the main beam 1. This design improves the stability and accuracy of clamping, and also increases the adaptability of the equipment, so that it can handle W-shaped through-beams 2 of different shapes and sizes.

[0038] The technical problem solved in cooperation with other components is to further optimize the process of inserting the W-shaped through beam 2 into the main beam 1. The cooperation between the arc groove 16 and the rotating clamp reduces the error and uncertainty in the installation process and improves the welding efficiency. The problem of low efficiency and difficulty in ensuring precision during manual installation and assembly is solved, and the overall efficiency and quality of trailer production are effectively improved.

[0039] Furthermore, it also includes a first elastic member 17 and a second elastic member 18, one end of the first elastic member 17 and the second elastic member 18 act on the groove wall of the arc groove 16, and the other end acts on the second clamp 10 or the third clamp 11, the first elastic member 17 and the second elastic member 18 are respectively located on both sides of the second clamp 10 or on both sides of the third clamp 11, for providing a force to center the second clamp 10 and the third clamp 11 in the arc groove 16; the pushing sleeve 19 is slidably arranged between the first elastic member 17 and the second clamp 10, and between the second elastic member 18 and the second clamp 10, and the second clamp 10 is rotatably arranged relative to the pushing sleeve 19.

[0040] In this embodiment, one end of the first elastic member 17 and the second elastic member 18 acts on the groove wall of the arc groove 16, and the other end acts on the second clamp 10 or the third clamp 11 respectively, and is located on both sides of the second clamp 10 or the third clamp 11. The design principle is to use the elastic force of the elastic member to provide the second clamp 10 and the third clamp 11 with a force to center in the arc groove 16, so that the clamps can be maintained in a relatively stable position when not affected by other external forces. The technical effect of the first elastic member 17 and the second elastic member 18 is that they can ensure the position stability of the second clamp 10 and the third clamp 11 in the arc groove 16. In the process of clamping the W-shaped through-beam 2, even if it is disturbed by a certain external force, the elastic member can quickly return the clamp to the center position, thereby improving the accuracy and stability of the clamping. At the same time, the presence of the elastic member also provides a certain buffering effect for the clamp, reducing the collision and wear between the clamp and other components.

[0041] In this embodiment, the pushing sleeve 19 is slidably arranged between the first elastic member 17 and the second clamp 10 and between the second elastic member 18 and the second clamp 10, and the second clamp 10 is rotatably arranged relative to the pushing sleeve 19. The design principle is that the magnitude and direction of the force exerted by the elastic member on the clamp can be adjusted by sliding the pushing sleeve 19. When the position of the clamp needs to be adjusted, the compression degree of the elastic member can be changed by pushing the pushing sleeve 19, thereby achieving fine adjustment of the position of the clamp. The technical effect of the pushing sleeve 19 is that it provides a convenient way to adjust the position of the clamp. In the process of installing the W-shaped through-beam 2, the position of the clamp can be flexibly adjusted according to actual conditions, thereby improving the accuracy and efficiency of the installation. At the same time, the cooperation between the pushing sleeve 19 and the elastic member makes the position adjustment of the clamp more stable and accurate, reducing errors during the installation process.

[0042] The technical problem solved by these components is to further improve the accuracy and efficiency of inserting the W-shaped through beam 2 into the main beam 1. Through the action of the elastic member and the push sleeve 19, the position of the second clamp 10 and the third clamp 11 in the arc groove 16 is more stable and adjustable, reducing the difficulty and uncertainty of manual operation. The technical problem of low overall welding efficiency caused by manual installation and assembly is effectively solved, and the overall quality and efficiency of trailer production are improved.

[0043] Furthermore, the center of the arc groove 16 on the second clamp 10 is the center of the first rotating clamp 13 , and the center of the arc groove 16 on the third clamp 11 is the center of the second rotating clamp 14 .

[0044] In this embodiment, the center of the arc groove 16 on the second clamp 10 is the center of the first rotating clamp portion 13 , and the center of the arc groove 16 on the third clamp 11 is the center of the second rotating clamp portion 14 .

[0045] The design principle is to set the center of the arc groove 16 as the center of the corresponding rotating clamp, so that the second rotating clamp 14 and the third rotating clamp 15 can rotate more smoothly and accurately in the arc groove 16. Such a design can ensure that the clamp always rotates around a fixed center of the circle during the rotation process, so as to better adapt to the shape and installation requirements of the W-shaped through-beam 2. The technical effect is that this design improves the movement accuracy and stability of the second rotating clamp 14 and the third rotating clamp 15 in the arc groove 16. The clamp can adjust the angle and position more accurately to clamp the corresponding part of the W-shaped through-beam 2, and perform more precise operations during the insertion of the I-shaped opening 101 of the main beam 1. At the same time, this design also makes the structure of the clamp more compact and reasonable, and improves the overall performance of the equipment. The technical problem solved in collaboration with other components is to further optimize the process of inserting the W-shaped through-beam 2 into the main beam 1. Through precise rotation design, the errors and uncertainties in the installation process are reduced, and the welding efficiency is improved. The problem of low efficiency and difficulty in ensuring precision during manual operation and installation is solved, and the overall efficiency and quality of trailer production are effectively improved.

[0046] Furthermore, the first clamp 9 , the second clamp 10 and the third clamp 11 are all parallel clamps.

[0047] In this embodiment, the first clamp 9, the second clamp 10 and the third clamp 11 are all parallel clamps. The design principle is that the parallel clamp can provide a stable and uniform clamping force to ensure that the corresponding parts of the W-shaped through-beam 2 are firmly clamped. The design of the parallel clamp can make the two clamps parallel when the clamp clamps the object, so as to better adapt to the shape of the W-shaped through-beam 2 and improve the stability and accuracy of the clamping. The technical effect is that the parallel clamp can provide a reliable clamping force to ensure that the W-shaped through-beam 2 will not loosen or fall off during the installation process. At the same time, the operation of the parallel clamp is relatively simple, and the W-shaped through-beam 2 can be clamped and released quickly, which improves the efficiency of installation. In addition, the structure of the parallel clamp is relatively compact, occupies a small space, and is suitable for operation in a limited space. The technical problem solved in coordination with other components is to further improve the accuracy and efficiency of the insertion of the W-shaped through-beam 2 into the main beam 1. The parallel clamp cooperates with other components to reduce the difficulty and uncertainty of manual operation, effectively solve the technical problem of low overall welding efficiency caused by manual operation installation and assembly, and improve the overall quality and efficiency of trailer production.

[0048] Furthermore, it also includes an automatic welding gun, which is three-dimensionally movable and arranged above the two main beams 1.

[0049] In this embodiment, the three-dimensional movement of the automatic welding gun is set above the two main beams 1. Through the three-dimensional movement function of the automatic welding gun, the connection part of the W-shaped through-beam 2 and the main beam 1 can be welded at different positions and angles. The design of three-dimensional movement enables the welding gun to flexibly adjust its position to adapt to different welding requirements. The three-dimensional movement of the automatic welding gun improves the accuracy and efficiency of welding. It can accurately locate the part that needs to be welded to ensure the quality of welding. At the same time, the use of the automatic welding gun reduces the labor intensity and error of manual welding and improves the degree of automation of production. In addition, the function of three-dimensional movement enables the welding gun to operate in a complex welding environment and adapt to trailer frames of different shapes and sizes. The overall efficiency and quality of trailer production are further improved. The automatic welding gun cooperates with other components to realize the automatic insertion and welding of the W-shaped through-beam 2, reduce the difficulty and uncertainty of manual operation, and effectively solve the technical problem of low overall welding efficiency caused by manual operation, installation and assembly.

[0050] This embodiment also provides a method for using the welding device, which uses the welding device for trailer production to weld the main beam 1 and a plurality of W-shaped through beams 2 of the trailer.

[0051] In this embodiment, a method for welding the main beam 1 and a plurality of W-shaped through beams 2 of a trailer using a welding device for trailer production is detailed.

[0052] First, the two main beams 1 are lifted respectively by the first lifting seat 3 and the second lifting seat 4, and the height position of the main beam 1 is accurately adjusted to provide a suitable space for the installation of the W-shaped through beam 2, so that the I-shaped opening 101 of the main beam 1 is better aligned with the W-shaped through beam 2.

[0053] Next, the positions of the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 are adjusted by using the longitudinal moving member 5 and the transverse moving member 12, so that the first clamping member 9, the second clamping member 10 and the third clamping member 11 on them correspond to the first upper transverse portion 201, the second upper transverse portion 203 and the third upper transverse portion 205 of the W-shaped through-beam 2. According to different installation stages, appropriate clamping members are selected to clamp the W-shaped through-beam 2, and the angle of the W-shaped through-beam 2 is further adjusted by using the first rotating clamping member 13, the second rotating clamping member 14 and the third rotating clamping member 15, so that it can be smoothly inserted into the I-shaped opening 101 of the main beam 1.

[0054] During the insertion process, the second rotating clamp 14 and the third rotating clamp 15 can rotate and slide in the arc groove 16 of the second clamp 10 and the third clamp 11. At the same time, the first elastic member 17 and the second elastic member 18 and the pushing sleeve 19 can adjust the position of the clamps to ensure the stability and accuracy of clamping.

[0055] After the W-shaped through beam 2 is inserted into place, the automatic welding gun is moved three-dimensionally to the welding position for welding operation to ensure the welding quality.

[0056] The design principle is to achieve the automated installation and welding of the W-shaped through-beam 2 and the main beam 1 through the synergy of various components, thereby improving production efficiency and quality. The technical effect is that this welding method greatly improves the efficiency and accuracy of trailer production. It reduces the workload and errors of manual operation, ensuring that the connection between the W-shaped through-beam 2 and the main beam 1 is firm and reliable. At the same time, the automated welding process improves the safety and stability of production. The technical problem solved is that the problem of low efficiency of inserting the W-shaped through-beam 2 into the main beam 1 in traditional trailer production and low overall welding efficiency caused by manual installation and assembly is completely solved, providing an efficient and accurate solution for trailer production.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
