DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-3 In this embodiment, a fixture for welding and processing an automobile anti-collision beam includes a bracket 1 and a processing table 2, and the processing table 2 is fixedly connected to the top of the bracket 1.

[0024] In this embodiment, a clamping assembly is provided on the upper side of the processing table 2, and the clamping assembly includes two electric guide rails 3, which are fixedly installed on the top of the processing table 2, and slides 4 are slidably installed on the outer sides of the two electric guide rails 3, and the upper sides of the two slides 4 are fixedly connected with mounting columns 5, and the inner sides of the two mounting columns 5 are rotatably installed with rotating shafts 7, and the rotating shafts 7 pass through the inner sides of the mounting columns 5, and chucks 6 are fixedly installed on the opposite sides of the two rotating shafts 7, and the chuck 6 is a three-jaw chuck.

[0025] In this embodiment, a gear 8 is fixedly connected to the outer wall of the rotating shaft 7 on one side, and a limiting component is arranged on the outer side of the gear 8. The limiting component includes an adjusting rod 9 inserted into the inner side of the mounting column 5, and a spring 10 is sleeved on the outer wall of the adjusting rod 9. The lower end of the spring 10 abuts against a supporting plate 11, and the upper end of the spring 10 abuts against a protrusion 12. The lower end of the adjusting rod 9 is fixedly connected to a connecting plate 13, and the lower side of the connecting plate 13 is fixedly connected to a half gear 14, and the half gear 14 meshes with the gear 8.

[0026] It can be understood that, by fixing the half gear 14 , when the half gear 14 is meshed with the gear 8 , the gear 8 can be restricted from rotating, thereby fixing the gear 8 and the rotating shaft 7 .

[0027] It should be noted that the spring 10 is sleeved on the outer wall of the adjusting rod 9, and the support sheet 11 is fixedly connected to the outer wall of the adjusting rod 9. At the same time, there are two protrusions 12, and the two protrusions 12 are respectively arranged on the left and right sides of the adjusting rod 9. The two protrusions 12 are fixedly connected to the inside of the mounting column 5. The protrusions 12 and the support sheet 11 can limit the spring 10. When the adjusting rod 9 moves upward, the spring 10 can be squeezed by the support sheet 11. The position of the adjusting rod 9 can be elastically adjusted by using the spring 10, which facilitates operation.

[0028] It should be supplemented that a pull head 15 is fixedly connected to the upper end of the adjusting rod 9 . The pull head 15 is located on the upper side of the mounting column 5 . The pull head 15 is used to facilitate adjusting the position of the adjusting rod 9 .

[0029] Embodiment 2:

[0030] See also Figure 1 On the basis of the first embodiment, a bearing 16 is fixedly mounted on the outer wall of the mounting column 5, and the outer wall of the rotating shaft 7 is tightly matched with the inner ring of the bearing 16. The bearing 16 can provide a rotation support for the rotating shaft 7, thereby improving stability.

[0031] The working principle of the above embodiment is:

[0032] When the utility model is in use, the two chucks 6 respectively fix the two anti-collision beam workpieces that need to be welded together, and the two electric guide rails 3 respectively drive the two slides 4 to move left and right, so that the two chucks 6 are close to each other, so that the welding points of the two workpieces are butted against each other, and the staff holds the chuck 6 on the side where the limit assembly is not yet set to keep the positions of the two workpieces stable. When the welding surface needs to be replaced on one side after welding, the adjusting rod 9 is driven to move by the pull head 15, and the spring 10 is squeezed, and the connecting plate 13 is driven to move at the same time, so that the half gear 14 is away from the gear 8, and the positioning of the gear 8 can be released. Subsequently, the chuck 6 can be rotated by the activity of the rotating shaft 7 to adjust the welding surface of the workpiece. After the adjustment is completed, the pull head 15 is released, and the spring 10 resets the adjusting rod 9, so that the half gear 14 is re-engaged with the gear 8, so that the position of the workpiece after the welding surface is adjusted remains stable.
