Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an automobile parts welding tool. Background Art

[0002] Auto parts are the components that make up the whole car, including the engine, transmission, suspension system, brake system, electrical system, body structure, etc. In the process of automobile manufacturing, the parts of the car need to be welded, and the connection between the two parts needs to be completely welded. The traditional way is for workers to walk to the other side of the welded part to weld, which is inconvenient in the production process.

[0003] In order to reduce the burden on workers, the welding surface can be changed by rotating the parts in the clamp. The "A kind of welding fixture for automobile parts with the publication number 'CN219189183U'" discloses that the bearings and rotating shafts set in the disc can realize the effect of rotating the parts under the clamping of the fixture, so that after the workers have finished welding one side of the parts, they do not need to move to the other side of the parts to weld the parts. However, the above-mentioned fixture needs to rotate six clamping screws to clamp the parts during welding. In this process, the parts need to be supported to prevent them from falling, and the locking screws need to be rotated when the angle is rotated and limited. The workflow is cumbersome and it is difficult to reduce the work intensity of workers. Therefore, in order to solve the above problems, the present application provides a welding fixture for automobile parts.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0013] By driving the motor to rotate the first screw, the two clamping assemblies are brought close to each other, and the parts are placed between the two fixed plates. Due to the elastic force of the spring, the parts can be placed quickly so that they do not fall. The second screw is rotated, and the movable plate drives the second limit plate to move downward. The fixing force is adjusted until it is stably clamped. When the welding angle needs to be adjusted, the first tooth ring is slid to separate it from the second tooth ring.

Due to the elastic force of the first spring, the first tooth ring slides and engages with the second tooth ring, thereby limiting the rotation of the clamping assembly. Compared with the comparative document, the tooling realizes quick clamping and quick adjustment of the welding position. It is more convenient to use and improves work efficiency.

[0022] The limiting assembly 8 includes a fixed disk 801, the side wall of the left fixed disk 801 is fixedly connected to the second tooth ring 7, and the side wall of the right fixed disk 801 is rotatably connected to one end of the right connecting rod 4 near the center of the platform body 1. The side walls of the fixed disk 801 near the center of the platform body 1 are fixedly connected with three fixed plates 802, and the two lower fixed plates 802 are both through-set and slidably connected with sliding rods 803, and one end of the sliding rod 803 near the center of the fixed disk 801 is fixedly connected with a first limiting plate 805, and the outer wall of the sliding rod 803 is wound with a second spring 804, and the fixed plates 802 are elastically connected to one of the first limiting plates 805 through the second spring 804. The upper fixed plate 802 is provided with a second screw 806 which is threadedly connected thereto. The lower end of the second screw 806 is rotatably connected to a movable plate 807. The lower end of the movable plate 807 is fixedly connected to a telescopic rod 808. The lower end of the telescopic rod 808 is fixedly connected to a second limit plate 810. The second limit plate 810 is elastically connected to the lower wall of the movable plate 807 via a third spring 809 which is wound around the outer wall of the telescopic rod 808.

[0023] The components are placed between the two fixed plates 801. Due to the elastic force of the second spring 804 and the limiting effect of the first limiting plate 805, the components can be quickly placed in cooperation with the second limiting plate 810 so that they do not fall. The second screw 806 is rotated, and the movable plate 807 threadedly connected thereto moves downward. The telescopic rod 808 contracts and drives the second limiting plate 810 to move downward.
