Technical Field

[0001] This utility model relates to the field of laser welding equipment, and in particular to a mounting device for laser welding of chassis. Background Technology

[0002] With the rapid development of industries such as electronics, communications, and power, the manufacturing of chassis, as an important component of various equipment, places increasingly higher demands on welding precision and efficiency. Laser welding, due to its advantages such as high welding speed, high weld quality, and small heat-affected zone, is widely used in chassis panel welding.

[0003] In existing technologies, the problems encountered during laser welding of chassis are twofold. First, the fixing effect on chassis panels of different specifications and shapes is not ideal, and the panels are prone to loosening or displacement during the welding process, affecting the welding accuracy. Second, existing methods for handling welding fumes lack effective purification devices, causing environmental pollution. The structural design of purification components is not perfect, filter replacement is inconvenient, the purification effect is limited, and the filtration of harmful fumes is poor. Therefore, a chassis laser welding fixing device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a chassis laser welding fixing device, which aims to improve the problems of chassis plates easily loosening and shifting during welding and the harm to the human body caused by the fumes generated during welding in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chassis laser welding fixing device includes a worktable, a welding device on the top of the worktable, a shell at the bottom of the worktable, a support plate fixedly connected inside the shell, multiple fixed columns fixedly connected to both sides of the top of the support plate, a sliding column fixedly connected between two fixed columns, a sliding plate slidably connected between two sliding columns, a support column fixedly connected to the top of the sliding plate, a second fixed plate fixedly connected to the outside of the support column, a first fixed plate fixedly connected to the top of the support column, racks fixedly connected to opposite sides of the two second fixed plates, a motor fixedly connected to the bottom wall of the inner shell, a rotating shaft fixedly connected to the output end of the motor, a gear fixedly connected to the top of the rotating shaft, a chassis plate on the top of the worktable, and a purification component on the outside of the worktable.

[0007] As a further description of the above technical solution:

[0008] The purification assembly includes a purification chamber and an air pump. The output end of the air pump is fixedly connected to a flexible hose, and the end of the flexible hose away from the air pump is fixedly connected to the inside of the purification chamber. The input end of the air pump is fixedly connected to a plastic tube. Multiple fixing blocks are fixedly connected to the inner wall of the purification chamber. An activated carbon filter is provided on the top of every two fixing blocks. A sealed door is installed on the outside of the purification chamber.

[0009] As a further description of the above technical solution:

[0010] Both support plates extend through the top of the workbench and the outer casing, and are slidably connected inside the workbench.

[0011] As a further description of the above technical solution:

[0012] The chassis panel is located between the two fixing plates, and the opposite sides of the two fixing plates abut against the surface of the chassis panel.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the outside of the sealed door.

[0015] As a further description of the above technical solution:

[0016] The gear is located between the two racks, and the two racks mesh with the gear respectively.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the chassis panel is welded, the starting motor drives the rotating shaft to rotate, which in turn drives the gear to rotate. The two racks meshing with the gear begin to move, causing the fixing plates connected to the two racks to move closer to the middle until the chassis panel is stably clamped, thus fixing the chassis panel and preventing displacement during the welding process.

[0023] 2. In this utility model, during the welding process, by starting the air pump, the shaping tube draws air from the welding area, allowing the dust suction head to draw the fumes generated during welding into the purification chamber. The fumes are then purified and cleaned by multiple activated carbon filters. Finally, the qualified gas is released into the air through the exhaust pipe. When the activated carbon filters are purified to a certain extent, they can be removed and replaced to prevent air pollution. Attached Figure Description

Both support columns 12 penetrate the top of the worktable 1 and the shell 4 and are slidably connected inside the worktable 1. The chassis plate 5 is located between two fixed plates 13, with each of the two fixed plates 13 abutting against the surface of the chassis plate 5 on opposite sides. A gear 16 is located between two racks 15, with each rack 15 meshing with the gear 16. A rack 15 on one fixed plate 22 is slidably connected inside the other fixed plate 22.

[0033] The workbench 1 provides support in the device, the welding device 2 is used to weld the chassis panel 5, the outer shell 4 provides protection in the fixing device, the support plate 19 supports the various parts on its top to ensure normal operation, the fixed column 17 supports the sliding column 20, the sliding plate 21 drives the support column 12 to slide on the sliding column 20, the second fixed plate 22 drives the support column 12 to slide on the rack 16, the support column 12 fixes the top fixed plate 13, the motor 14 drives the rotating shaft 18 to rotate, thereby driving the gear 16 and the rack 15 to rotate, so that the fixed plate 13 connected to the rack 15 moves closer to the center, thus better fixing the chassis panel 5 during welding and preventing displacement.

[0034] Reference Figure 1 , Figure 5 The purification assembly includes a purification chamber 3 and an air pump 6. A flexible hose 9 is fixedly connected to the output end of the air pump 6, and the end of the flexible hose 9 furthest from the air pump 6 is fixedly connected to the inside of the purification chamber 3. A plastic tube 8 is fixedly connected to the input end of the air pump 6. Multiple fixing blocks 23 are fixedly connected to the inner wall of the purification chamber 3, and an activated carbon filter 24 is installed on the top of every two fixing blocks 23.

[0036] Working principle: In the fixing device of the laser welding machine chassis, the chassis plate 5 is placed between two fixing plates 13 on the worktable 1. Then, the motor 14 is started, driving the rotating shaft 18 to rotate, thereby driving the gear 16 to rotate. The two racks 15 meshing with the gear 16 begin to move. The sliding plate 21 slides on the sliding column 20 to ensure the smooth sliding of the racks 15 until the two fixing plates 13 clamp the chassis plate 5. The movement of the racks 15 is controlled by the forward and reverse rotation of the motor 14, thereby achieving the clamping and release of the chassis plate 5. Therefore, the chassis plate 5 is better fixed during welding. During the welding process, the shaping tube 8 can be adjusted to the welding position, and the air pump 6 is started. The harmful gases generated during the welding process will enter the shaping tube 8 through the dust suction head 7, and finally enter the purification box through the hose 9. After passing through each activated carbon filter 24, the finally purified gas is discharged through the exhaust pipe 10. When the activated carbon filter 24 is purified to a certain extent, it can be removed and replaced to prevent air pollution.
