The utility model relates to the technical field of automobile welding. The device has a reasonable structure, low cost, and is easy to use. After the workpiece is placed on the workbench, the workpiece can be automatically clamped by the clamping structure, and there is no need for the staff to manually clamp it, so as to prevent the clamping operation from being inconvenient, thereby reducing the clamping efficiency. The smoke exhaust structure can be used to absorb and filter the smoke generated by the workers when welding the weldment, and then discharged, which guarantees the health of the workers to the greatest extent, and also prevents the air from being polluted. The setting of the lighting lamp ensures that the workers can perform the welding operation normally even when the light is not good. However, various parts of the automobile often have different shapes, and when clamping and fixing them, they often need to use clamps of different shapes, and the clamping plate on the device is fixedly connected to one side of the moving plate, which is inconvenient to replace, resulting in a relatively limited scope of use of the device.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0018] Example

[0019] Please refer to Figure 1-Figure 3 As shown, the utility model provides a welding fixture for automobile welding, the anti-skid pad 13 is made of rubber material, which can not only play a protective role but also play a certain protective role on automobile parts. A fixing plate 14 is fixedly connected to the upper end of the workbench 1, and one side of the fixing plate 14 is connected to the first connecting plate 2 through a second spring 15. A limiting hole 16 is provided on the workbench 1, and a limiting plate 17 is fixedly connected to the lower end of the second connecting plate 3. One end of the limiting plate 17 passes through the limiting hole 16 and extends to one side of the workbench 1. A connecting block 18 is fixedly connected to the lower end of the workbench 1, and an electric telescopic rod 19 is arranged on the connecting block 18, and the output end of the electric telescopic rod 19 is fixedly connected to the limiting plate 17, and support legs 20 are fixedly connected to the top corners of the lower end of the workbench 1.

[0020] When in use, by starting the electric telescopic rod 19, the electric telescopic rod 19 can drive the limit plate 17 and the second connecting plate 3 to move, and at the same time the limit hole 16 can limit the limit plate 17, so that the movement of the limit plate 17 and the second connecting plate 3 can be more stable. When the arc clamp 10 on the second connecting plate 3 is in contact with the automobile part, the first connecting plate 2 will move to one side and compress the second spring 15. At the same time, the second spring 15 can play a certain buffering role until the two clamps finally clamp the automobile part well.

[0021] As a further implementation of this embodiment, Figure 1-Figure 4 As shown, the first connecting plate 2 and the second connecting plate 3 have the same structure, and the upper ends of the first connecting plate 2 and the second connecting plate 3 are fixedly connected with a bracket 21, and a vertical rod 4 is arranged through the upper end of the bracket 21, and one end of the vertical rod 4 is fixedly connected with a horizontal plate 5, and the lower end of the horizontal plate 5 is fixedly connected with a limiting block 6, and a first spring 7 is arranged between the horizontal plate 5 and the bracket 21, and a handle 8 is fixedly connected to the upper end of the vertical rod 4. A card slot 9 is provided on the first connecting plate 2 and the second connecting plate 3, and the card slot 9 cooperates with the card block 11 on the arc clamp 10, and a limiting groove 12 is provided on the card block 11, and the limiting block 6 can pass through the through hole on the first connecting plate 2 and be inserted into the limiting groove 12, and an anti-slip pad 13 is provided on one side of the arc clamp 10.

[0022] When in use, by pulling the handle 8, the handle 8 drives the vertical rod 4 and the horizontal plate 5 to move upward, the first spring 7 is compressed, and at the same time, the limit block 6 at the lower end of the horizontal plate 5 will leave the limit groove 12 on the clamping block 11, and the arc clamp 10 is no longer limited and fixed, so that the arc clamp 10 can be easily replaced with clamps of different shapes and types. Through this device, the clamps can be easily and quickly replaced, so that different automobile parts can be clamped and fixed well.

[0023] Specific working principle: when in use, by pulling the handle 8, the handle 8 drives the vertical rod 4 and the horizontal plate 5 to move upward, the first spring 7 is compressed, and at the same time the limit block 6 at the lower end of the horizontal plate 5 will move upward and leave the limit groove 12 on the clamping block 11, and the limit block 6 can pass through the through hole on the first connecting plate 2 and move to the top of the first connecting plate 2, and the arc clamp 10 is no longer limited and fixed, so that the clamping block 11 on the arc clamp 10 can be taken out of the clamping groove 9, which is convenient for replacing the arc clamp 10 with clamps of different shapes and types. The clamp can be replaced quickly and conveniently through the device, so that different automobile parts can be clamped and fixed well. When the clamp is replaced After completion, the automobile component is placed on the workbench 1, and one side of the automobile component is brought into contact with the clamp on the first connecting plate 2, and then the electric telescopic rod 19 is started. The electric telescopic rod 19 can drive the limit plate 17 and the second connecting plate 3 to move, and at the same time play a limiting role in the limit hole 16, so that the movement of the limit plate 17 and the second connecting plate 3 can be made more stable. When the clamp on the second connecting plate 3 contacts and squeezes the automobile component, it will drive the first connecting plate 2 to move to one side and compress the second spring 15, and the contraction of the second spring 15 can play a certain buffering role, which can protect the automobile component, until the two clamps finally clamp the automobile component well.

[0024] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
