Its design and manufacture have an important impact on the performance and safety of the whole vehicle, provide necessary support for the roof, and enhance the stiffness and stability of the roof. The outer plate of the rear cross beam of the automobile roof needs to be welded during the processing. In order to prevent the outer plate from shifting during the welding process, a positioning device is required.

[0003] However, when some existing welding auxiliary positioning devices are put into use, the staff need to place the cross beam outer plate on the top of the workbench and then weld the cross beam outer plate through a laser.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6As shown in the figure, a welding auxiliary positioning device for the outer plate of the rear crossbeam of a car roof includes a workbench 1. The workbench 1 enables the processing of the crossbeam outer plate on its top. A welding assembly 2 is arranged on the top of the workbench 1. The welding assembly 2 processes and welds the crossbeam outer plate through the cooperation of a hydraulic rod and a laser. A positioning assembly 3 is bolted to the top of the workbench 1. The positioning assembly 3 limits and fixes the crossbeam outer plate through a hydraulic rod and a clamping plate. A stepping motor 4 is bolted to one side of the workbench 1. A fixed shell 5 is bolted to the bottom of the workbench 1. A rotating mechanism 6 is arranged on one side of the stepping motor 4. With the cooperation of the stepping motor 4 and the fixed shell 5, the rotating mechanism 6 can work. A connecting plate 7 is slidably connected to the inner cavity of the workbench 1. Under the action of the rotating mechanism 6, the connecting plate 7 can move left and right on the surface of the workbench 1. One side of the connecting plate 7 is rotatably connected to a brush 8. Under the action of the connecting plate 7, the brush 8 can move on the surface of the crossbeam outer plate. The brush 8 can clean the crossbeam outer plate, effectively reducing the situation that the welding effect decreases due to dust on the surface of the crossbeam outer plate. The other end of the brush 8 is rotatably connected to a guide block 9. A guide rod 10 is fixedly connected to one side of the workbench 1. The inner cavity of the guide block 9 is slidably connected to the surface of the guide rod 10. With the cooperation of the guide block 9 and the guide rod 10, it effectively prevents the brush 8 from shifting in position during work, increasing the stability of the brush 8, and thus increasing the stability of the device. A connecting shell 11 is bolted to one side of the welding assembly 2. A fan 12 is installed in the inner cavity of the connecting shell 11. Under the action of the internal guide rail of the welding assembly 2 driving the hydraulic rod to move, the connecting shell 11 can move left and right above the crossbeam outer plate following the welding assembly 2. With the cooperation of the fan 12, the harmful gases generated during the work of the welding assembly 2 can enter the inner part of the connecting shell 11. An installation shell 13 is slidably connected to the inner cavity of the connecting shell 11. An activated carbon filter group 14 is installed in the inner cavity of the installation shell 13. The number of the activated carbon filter groups 14 is three and they are equidistantly designed in the inner cavity of the connecting shell 11. With the cooperation of the number of the activated carbon filter groups 14, it can filter the harmful gases more comprehensively. A handle 15 is bolted to one side of the installation shell 13. The handle 15 is of a hollow design. Under the action of the handle 15, it is convenient for the staff to drive the activated carbon filter group 14 to move out of the inner part of the connecting shell 11 through the installation shell 13. A limiting mechanism 16 is arranged on one side of the connecting shell 11. Under the action of the limiting mechanism 16, it can effectively prevent the installation shell 13 from shifting in position during work, increasing the stability of the installation shell 13, and thus increasing the stability of the device.

[0025] The rotating mechanism 6 includes a rotating rod 61. One end of the rotating rod 61 is fixedly connected to the output shaft of the stepping motor 4. The other end of the rotating rod 61 is fixed with a threaded rod 62. The other end of the threaded rod 62 is fixedly connected to the inner cavity of the fixed shell 5 through a bearing seat. A sleeve 63 is threadedly connected to the surface of the threaded rod 62. The top of the sleeve 63 is bolted to the bottom of the connecting plate 7. With the cooperation of the stepping motor 4 and the rotating rod 61, the threaded rod 62 can drive the connecting plate 7 to move through the sleeve 63, so that the connecting plate 7 drives the brush 8 to move, enabling the brush 8 to clean the outer plate of the cross beam, effectively reducing the influence of dust on the surface of the outer plate of the cross beam on welding, thus increasing the practicability of the device.

[0026] The limiting mechanism 16 includes a fixed rod 161. One end of the fixed rod 161 is bolted to one side of the connecting shell 11. A limiting plate 162 is slidably connected to the surface of the fixed rod 161. One side of the limiting plate 162 is fixed with a tension spring 163. The other side of the tension spring 163 is fixedly connected to one side of the connecting shell 11. Under the action of the movement of the limiting plate 162 on the surface of the fixed rod 161, the tension spring 163 can be stretched. Subsequently, by rotating the limiting plate 162, the installation shell 13 can be driven to drive the activated carbon filter group 14 to move, and under the action of the rebound of the tension spring 163, the limiting plate 162 can return to its original position, effectively preventing the installation shell 13 from shifting in position during operation, increasing the stability of the installation shell 13 during operation, and thus increasing the stability of the device.

[0027] Working principle: First, the staff places the crossbeam outer plate to be welded on the top of the workbench 1. Subsequently, with the cooperation of the hydraulic rod of the positioning component 3, the clamping plate can limit the crossbeam outer plate. Under the action of the stepping motor 4, the rotating rod 61 can drive the sleeve 63 to move in the inner cavity of the fixed housing 5 through the threaded rod 62. The sleeve 63 drives the brush 8 to move on the top of the crossbeam outer plate through the connecting plate 7, so that the brush 8 cleans the crossbeam outer plate. At the same time, the brush 8 drives the guide block 9 to move on the surface of the guide rod 10, making the movement of the brush 8 more stable. After the hydraulic rod of the welding component 2 drives the connecting housing 11 to descend, under the action of the guide rail, the welding component 2 can weld different positions of the crossbeam outer plate. At the same time, when cleaning the harmful gases generated during the operation of the welding component 2, under the action of the fan 12, the harmful gases can enter the inside of the connecting housing 11 and then be filtered through the activated carbon filter group 14. When the staff needs to replace the activated carbon filter group 14, with the cooperation of the limiting plate 162 and the fixed rod 161, the tension spring 163 can be stretched. Subsequently, rotate the limiting plate 162, and the handle 15 can drive the activated carbon filter group 14 to move out of the inside of the connecting housing 11 through the mounting housing 13. After the staff finishes replacing the activated carbon filter group 14, the limiting plate 162 rotates, and under the action of the rebound of the tension spring 163, the limiting plate 162 can limit the mounting housing 13. Subsequently, the staff can continue to operate the device.
