Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a welding control fixture. Background Technology

[0002] The crossbeam is the main supporting structural component of the storage and transportation container. It mainly supports the structure of the container. The crossbeam is composed of channel steel and end plates. The end plates are fastened to the channel steel and pre-connected to form the crossbeam. Then, the whole assembly is placed on the welding platform for overall welding and fixation.

[0003] Currently, welding is performed by attaching the sealing plate to the channel steel and placing it on a platform, then using a robot for welding. During the welding process, the crossbeam body undergoes large bending deformation, and it must be corrected after welding to ensure straightness before it can be used.

[0004] Because of the large quantity of crossbeams used, post-weld correction takes a lot of time, and the correction will affect the material stability of the crossbeams, resulting in low production efficiency and unstable product quality. Summary of the Invention

[0005] This application provides a welding control fixture that can solve the problem of time-consuming and labor-intensive post-weld correction of crossbeams in related technologies, which affects production efficiency.

[0006] This application provides a welding control fixture, including: a welding platform with a first control area and a second control area, wherein a welding station for placing a crossbeam is set between the first control area and the second control area; a pad installed on the welding platform and located in the middle of the welding station; and a clamping device installed on the welding platform and located in the first control area and the second control area respectively, wherein the clamping device is used to clamp the crossbeam at both ends of the welding station.

[0008] In some embodiments, the adjusting component includes a support and a connecting arm. The support is connected to the welding platform, one end of the connecting arm is connected to the support, and the other end extends toward the welding station and is connected to the pressing component. The pressing component is vertically adjusted on the connecting arm to maintain a vertical height relative to the crossbeam.

[0009] In some embodiments, an adjusting bolt is threaded onto the connecting arm, and a disc is hinged to the end of the adjusting bolt, the disc being fixedly connected to the pressing component.

[0010] In some embodiments, the pressing component includes a pressing rod and a connecting rod. The pressing rod abuts against the crossbeam body, and one end of the connecting rod is vertically connected to the pressing rod, while the other end is fixedly connected to the disc.

The base plate is connected to the welding platform, and the pressure block includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the base plate, and one end of the second connecting portion is connected to the top end of the first connecting portion, while the other end extends parallel to the welding platform and away from the first connecting portion, so that the positioning groove is formed between the welding platforms.

[0016] The beneficial effects of the technical solutions provided in this application include:

[0017] This application provides a method for welding a crossbeam by placing it at a welding station on a welding platform. At the welding station, the crossbeam is supported in the middle by a backing plate, and a clamping device presses down on both ends of the crossbeam. When the crossbeam is in the clamped state, the backing plate allows for reverse bending deformation of the crossbeam, which can counteract the bending deformation that occurs after the clamping device is released after welding. Simultaneously, the crossbeam remains clamped during welding, preventing deformation. By employing reverse deformation before welding and clamping during welding, the welding deformation of the crossbeam is controlled. This effectively controls the welding deformation of the crossbeam, solves the problem of large post-weld deformation, improves production efficiency and product quality, and saves on labor costs for correction.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0025] This application provides a welding control fixture that can solve the problem of time-consuming and labor-intensive post-weld correction of crossbeams in related technologies, which affects production efficiency.

[0026] See Figures 1 to 4As shown in the figure, this application provides a welding control fixture, including a welding platform 1, a pad 2, and a clamping device. The welding platform 1 has a first control area 10 and a second control area 11, with a welding station 12 for placing a crossbeam 13 between the first control area 10 and the second control area 11. The crossbeam 13 is placed on the welding station 12, and welding is completed at the welding station 12. To prevent bending deformation of the crossbeam 13 during welding, the pad 2 is installed on the welding platform 1, located in the middle of the welding station 12; the clamping device is installed on the welding platform 1, located in the first control area 10 and the second control area 11 respectively, and is used to clamp the crossbeam 13 at both ends of the welding station 12.

[0027] The crossbeam 13 is supported in the middle by a pad 2, and the clamping device presses against both ends of the crossbeam 13. When the crossbeam 13 is in the clamped state, the pad 2 can achieve the opposite bending deformation of the crossbeam 13, which can counteract the bending deformation of the crossbeam 13 after the clamping device is released after welding. At the same time, the crossbeam 13 is also in a clamped state during the welding process, and no deformation will occur during the welding process. By taking the reverse deformation before welding and the clamping during welding, the welding deformation of the crossbeam 13 is controlled. The welding deformation of the crossbeam 13 is effectively controlled, the problem of large deformation of the crossbeam 13 after welding is solved, the production efficiency and product quality of the crossbeam 13 are improved, and the labor cost of correction is saved.

[0028] In this application, the pad 2 includes a pad block 20 and a support block 21. The pad block 20 is bolted to the welding platform 1, and the support blocks 21 are respectively located at both ends of the pad block 20 and are also detachably connected to the pad block 20 by bolts. The two support blocks 21 are used to contact the crossbeam 13. In use, the crossbeam 13 is supported on the support blocks 21, which are preferably 5mm thick. The support blocks 21 directly support the crossbeam 13, and the pad block 20 provides a stable foundation for the support blocks 21. When the crossbeam 13 is in a compressed state, the pad 2 can achieve bending deformation of the crossbeam 13 in the opposite direction, which can counteract the bending deformation of the crossbeam 13 after the compression device is released after welding.

[0029] In this application, the clamping device includes a first clamping assembly and a second clamping assembly. The first clamping assembly includes a pressing component 3 and an adjusting component 4. The adjusting component 4 is installed within the first control area 10, and the pressing component 3 is connected to the adjusting component 4. The vertical height of the pressing component 3 relative to the crossbeam 13 can be vertically adjusted via the adjusting component 4. Specifically, the adjusting component 4 includes a support 40 and a connecting arm 41. The support 40 is connected to the welding platform 1. One end of the connecting arm 41 is connected to the support 40, and the other end extends toward the welding station 12 and is connected to the pressing component 3. The vertical height of the pressing component 3 relative to the crossbeam 13 is vertically adjusted via the connecting arm 41.

[0030] By connecting the support 40 to the welding platform 1, a stable support point is provided for the entire adjusting component 4. Furthermore, with the connection of the connecting arm 41, the pressing component 3 can be accurately positioned at the welding station 12 attachment, specifically at one end of the crossbeam 13. To further improve positioning accuracy, the pressing position and angle of the pressing component 3 are precisely adjusted. The connecting arm 41 is rotatably connected to the support 40; rotating the connecting arm 41 effectively provides accurate positioning for the pressing component 3, contributing to improved welding accuracy and quality. Since the shape, size, and welding requirements of different workpieces vary during welding operations, the vertical height between the pressing component 3 and the crossbeam 13 needs to be flexibly adjusted according to the actual situation. Therefore, by vertically adjusting the vertical height between the pressing component 3 and the crossbeam 13 via the connecting arm 41, the vertical distance between the pressing component 3 and the crossbeam 13 can be precisely adjusted, ensuring that the pressing component 3 applies appropriate pressure to the workpiece during welding, maintaining a stable position and posture for the workpiece.

[0031] In this application, to facilitate the adjustment of the connection height of the pressing component 3, an adjusting bolt 5 is threaded onto the connecting arm 41, and a disc 6 is hinged to the end of the adjusting bolt 5. The disc 6 is fixedly connected to the pressing component 3. The adjusting bolt 5 and the connecting arm 41 are connected by a thread. By rotating the adjusting bolt 5, the extension length of the adjusting bolt 5 on the connecting arm 41 can be changed. When the adjusting bolt 5 extends, it will cause the disc 6 and the pressing component 3 to extend together. Furthermore, when the adjusting bolt 5 is rotated, due to the presence of the thread, a force is generated along the axis of the adjusting bolt 5. This force can be decomposed into an axial component and a circumferential component when the adjusting bolt 5 moves up and down. Under the action of the disc 6 hinged to the adjusting bolt 5, the disc 6 will move downward. That is, the axial component will cause the pressing component 3 connected to the adjusting bolt 5 to produce linear motion. Thus, it is easier to tighten the crossbeam by rotating the adjusting bolt 5.

[0032] In this application, the pressing component 3 includes a pressing rod 30 and a connecting rod 31. The pressing rod 30 abuts against the crossbeam 13, and one end of the connecting rod 31 is perpendicularly connected to the pressing rod 30, while the other end is fixedly connected to the disc 6. The transverse width of the pressing rod 30 is consistent with the width of the crossbeam 13, enabling it to press against multiple beams. The connecting rod 31 effectively connects the pressing rod 30 and the disc 6, resulting in a reliable structure.

[0033] In this application, the second clamping assembly is installed within the second control area 11. The second clamping assembly has a positioning groove 14 for engaging the crossbeam 13. In practical use, one end of the crossbeam 13 is positioned and clamped by engaging with the positioning groove 14, while the other end is fixed by the pressure of the pressure rod 30. The crossbeam 13 remains clamped during welding, preventing deformation during the welding process.

[0034] In this application, the second clamping assembly includes a base plate 70 and a clamping block 71. The base plate 70 is bolted to the welding platform 1. The clamping block 71 includes a first connecting part 710 and a second connecting part 711, which form an L-shape. The first connecting part 710 is connected to the base plate 70, and one end of the second connecting part 711 is connected to the top of the first connecting part 710. The other end extends parallel to the welding platform 1 and away from the first connecting part 710, so that the positioning groove 14 is formed between the welding platforms 1. In use, one end of the crossbeam 13 is clamped between the welding platform 1 and the second connecting part 711 for positioning and clamping, which is convenient to operate. Furthermore, gaskets 8 are provided at the connection points of the pad plate 2 and the second clamping assembly on the welding platform 1. The gaskets 8 can control the welding deformation of crossbeams 13 of different specifications, and have a wide range of applications.

[0035] In this application, both the first and second clamping components can be detachably connected to the welding platform 1 using bolts. This allows for convenient installation and use, resulting in high practicality. Specifically, the support 40 is connected to the welding platform 1 using bolts, and the base plate 70 is also connected to the welding platform 1 using bolts.
