Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to an automobile bumper welding device. Background Art

[0002] Car bumpers not only serve as decorations, but also absorb and mitigate external impact forces, and protect the front and rear parts of the car body. They are very important safety performance components in automobile production. There are three main types of welding for bumpers in the actual production process: resistance welding, induction welding and laser welding. Among them, resistance welding has become the most preferred method for bumper production due to its advantages such as the best cost-effectiveness, low equipment price, low product molding requirements, and easy quantification of welding parameters and performance.

[0003] The application number is CN202222781911.5, which discloses a car bumper welding device, including an outer shell, the inner surface of which is fixedly connected with a plurality of collecting plates, the inner surfaces of which are fixedly connected with a support frame, and the inner surface of which is provided with a plurality of second chutes. In the utility model, the outer shell is provided to block the splashing debris, the inclined surface of the collecting plate is provided to facilitate the collection of the debris transmitted from the conveyor belt, the fixed plate, the groove, the second chute and the slider are provided to facilitate the pulling out of the collecting box for cleaning, and these settings make it easier to clean and collect the debris, avoid the splashing debris from injuring the staff, and reduce safety hazards.

[0004] This device is only used during the welding process. The bumper is transported by a conveyor belt and there is no fixing device. The conveyor belt will vibrate during the transportation process, which can easily cause the bumper to shake and collide with the device, resulting in damage. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a vehicle bumper welding device, comprising a fixed column, the top of which is fixedly connected to an operating table, and a moving mechanism, wherein the moving mechanism comprises two fixed plates fixedly connected to the top of the operating table, a sliding rod fixedly connected to one side of the two fixed plates close to each other, a sliding block slidably connected to an outer wall of the sliding block, and a first threaded rod rotatably connected to one side of the two fixed plates close to each other, and the first sliding block is limited by the sliding rod to prevent the sliding block from rotating with the first threaded rod.

[0007] Furthermore, the left end of the first threaded rod passes through the side wall of the left fixed plate and extends, the outer wall of the first threaded rod is threadedly connected to the inside of the slider, the left end of the first threaded rod is fixedly connected to the first servo motor, and the bottom of the first servo motor is fixedly connected to the side of the operating table away from the fixed column. This arrangement is to drive the first threaded rod to rotate by the first servo motor, thereby moving the first slider.

[0008] Furthermore, a fixing mechanism is arranged above the slider, and the fixing mechanism includes a placement plate fixedly connected to the top of the slider, and a rubber pad is fixedly connected to the central axis of the placement plate on the side away from the slider. This arrangement is to protect the car bumper with the rubber pad to prevent the bumper from being scratched.

[0010] Furthermore, a turntable is fixedly connected to the left end of the bidirectional threaded rod, a handle is fixedly connected to the end of the turntable away from the bidirectional threaded rod, and two second sliders are threadedly connected to the outer wall of the bidirectional threaded rod. This arrangement is to drive the bidirectional threaded rod to rotate by rotating the turntable, thereby adjusting the position of the second slider.

[0011] Furthermore, the second slider is slidably connected inside the slide groove, and the ends of the two second sliders away from the placement plate are fixedly connected to clamping rods, and the sides of the two clamping rods close to each other are fixedly connected to protective pads. This arrangement is to prevent damage to the bumper during the clamping process through the protective pads.

[0012] Furthermore, a welding mechanism is arranged above the operating table, and the welding mechanism comprises a U-shaped frame fixedly connected to the top of the operating table, and a second threaded rod is rotatably connected to the inside of one end of the U-shaped frame away from the operating table, and the front end of the second threaded rod passes through the front side of the placement plate and extends.

This arrangement is to drive the welding head to move up and down through the electric telescopic rod.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model rotates the handle counterclockwise, the handle drives the turntable to rotate, and the turntable drives the bidirectional threaded rod to rotate. Since the threads at both ends of the bidirectional threaded rod are opposite, the two second sliders will move away from each other, thereby driving the clamping rods to move away from each other, placing the bumper on the rubber pad, and then rotating the handle clockwise to make the two clamping rods approach each other, so that the protective pad and the bumper fit tightly, thereby fixing the bumper to prevent it from falling off during the welding process.
