Figures 1 to 9As shown in the figure, the present invention provides an automatic clamping and welding platform for energy-absorbing boxes, which is used to realize the automatic clamping and positioning of energy-absorbing boxes followed by assembly and welding operations. It adapts to both automation and manual intervention needs, facilitating mass production.

The third clamping unit 3 includes a third driving mechanism 31 and a third clamping assembly 32. The third clamping assembly 32 can be flipped and switched under the drive of the third driving mechanism 31, thereby achieving the pressing and opening action of the third clamping assembly 32 on the upper part of the portion of the energy-absorbing box (which can be understood as the left half of the energy-absorbing box 71). The first positioning pin 14 is connected to the positioning contact of the energy-absorbing box to achieve the positioning of a portion of the energy-absorbing box. The positioning of the energy-absorbing box is achieved by the first positioning pin 14 adapting to the pin hole of the corresponding part of the energy-absorbing box and engaging with it. One or more first positioning pins 14 can be set as needed.

[0036] In an embodiment of the present invention, an automatic clamping welding platform for energy-absorbing boxes includes a second clamping unit 2 and a fourth clamping unit 4 mechanically fixed to a workbench for positioning and clamping another part of the energy-absorbing box (which can be understood as the right half of the energy-absorbing box 72). More specifically, the second clamping unit 2 includes two second driving mechanisms 21, two second clamping components 22, a second mounting bracket 23, and a second positioning pin 24. The second driving mechanisms 21 and the second positioning pin 24 are mechanically fixed to the second mounting bracket 23, and the two second driving mechanisms 21 and the two second clamping components 22 are...

The second positioning pin 24 is connected to the positioning contact of the energy-absorbing box to realize the positioning of the other part of the energy-absorbing box. The positioning of the energy-absorbing box is achieved by the second positioning pin 24 adapting to the pin hole of the corresponding part of the energy-absorbing box and engaging with it.

[0037] In an embodiment of the present invention, an automatic clamping welding platform for an energy-absorbing box is preferably provided, wherein the first drive mechanism 11, the second drive mechanism 21, the third drive mechanism 31, the fourth drive mechanism 41, the fifth drive mechanism 51, and the sixth drive mechanism 61 are all driven by cylinders. This fully utilizes the characteristics of cylinders, such as fast action and good economy, to improve the response speed of the platform and accelerate the production cycle.

[0039] In an embodiment of the present invention, an automatic clamping and welding platform for an energy-absorbing box is further improved by the first clamping unit 1 by including a first positioning block 16. The first positioning block 16 is disposed on the first mounting bracket 13 and mechanically connected to the third clamping unit 3 to achieve position positioning during the clamping process of the third clamping unit 3. Through the positioning contact between the third clamping component 32 and the first positioning block 16, the shaking phenomenon during the movement of the third clamping component 32 can be effectively prevented, the clamping accuracy can be improved, and the clamping force of the third clamping component 32 can be effectively controlled to prevent it from continuing to apply large pressure to the energy-absorbing box after it is in position, thus avoiding large deformation of the energy-absorbing box and ensuring the welding accuracy of the energy-absorbing box assembly. The second clamping unit 2 further includes a second positioning block 26, which is disposed on the second mounting bracket 23 and mechanically connected to the fourth clamping unit 4 to achieve position positioning during the clamping process of the fourth clamping unit 4.

[0040] In an embodiment of the present invention, an automatic clamping welding platform for energy-absorbing boxes includes, as a further design improvement, a first clamping unit 1 further comprising: a first sensor 17, which is mounted on a first mounting bracket 13 for identifying the state of the energy-absorbing box on the first clamping unit 1; and a second clamping unit 2 further comprising: a second sensor 27, which is mounted on a second mounting bracket 23 for identifying the state of the energy-absorbing box on the second clamping unit 2. Preferably, both the first sensor 17 and the second sensor 27 are proximity switches, which can identify the state of the energy-absorbing box at the corresponding location to improve operational reliability, prevent malfunctions, and enhance the level of intelligence.

The fifth clamping unit 6 is equipped with a sixth driving mechanism 61 and a sixth clamping assembly 62. The sixth driving mechanism 61 can drive the sixth clamping assembly 62 to switch between clamping and releasing actions. After the movable base 53 is in position, the sixth clamping assembly 62 clamps the movable base 53, which can further improve the reliability of operation, prevent the movable base 53 from springing back after being in position, and ensure... Figure 9 The positioning accuracy of the left half of the energy-absorbing box 71 and the right half of the energy-absorbing box 72 in a certain model of the vehicle is not affected.

[0042] In an embodiment of the present invention, an automatic clamping welding platform for an energy-absorbing box is further improved by the translation device 5, which includes at least one flexible buffer component 56. The flexible buffer component 56 is disposed on the fixed base 52 and is in contact with the movable base 53 to buffer the movement of the movable base 53, so as to prevent the movable base 53 from making hard contact or collision with the parts on the fixed base 52, and also to avoid the parts on the movable base 53 from becoming loose due to frequent collisions, thus affecting the clamping and positioning accuracy.

[0043] In a further design improvement of the automatic clamping welding platform for energy-absorbing boxes according to an embodiment of this utility model, the translation device 5 also includes a manual pushing component 57. The movable base 53 is connected to the fixed base 52 via the manual pushing component 57 to enable manual intervention operation of the movable base 53. By manually operating the manual pushing component 57, the automatic clamping welding platform for energy-absorbing boxes can be pre-tested or pre-clamped, allowing for early detection of problems. By using the manual pushing component 57, this embodiment of the utility model can adapt to both automated and semi-automated production lines, improving its adaptability and versatility.

Then, the fourth clamping unit 4 clamps the upper part of the right half of the energy-absorbing box 72 accordingly. The left half of the energy-absorbing box 71 of the energy-absorbing box 7 of the certain vehicle model is placed on the first clamping unit 1 and positioned and clamped by manual labor or intelligent robot. Then, the third clamping unit 3 clamps the upper part of the left half of the energy-absorbing box 71 accordingly. Then, the translation device 5 drives the moving base 53 and moves the first clamping unit 1 and the third clamping unit 3 toward the position of the right half of the energy-absorbing box 72, so as to realize the splicing of the left half of the energy-absorbing box 71 and the right half of the energy-absorbing box 72. Then, the intelligent robot uses a welding gun to automatically weld the spliced ​​part of the energy-absorbing box 7 of the certain vehicle model. After the welding is completed, the reverse process action is performed to realize the unloading operation of the energy-absorbing box 7 of the certain vehicle model.
