Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

Please refer to FIGS. 1-6 , the present utility model provides a technical solution: a welding mold for automobile cross beams that is convenient and precise for butt joint, comprising a welding assembly 1 , and the welding assembly 1 includes a mold body 11 , a transmission device 12 and a pressure welding device 13 , One end of the transmission device 12 is fixedly connected to the top of the mold body 11, and the other end is connected to the pressure welding device 13, and also includes a clamp assembly 2. The clamp assembly 2 includes an adjustment part, a transmission plate 22, a pressure plate 23 and an adjustment bolt 24. The driving plate 22 and the pressure plate 23 are both slidably connected to the mold body 11 , and the adjusting bolt 24 is screwed through and connected to the pressure plate 23 and is rotatably connected to the transmission plate 22 .

In this embodiment, the transmission device 12 can generally be selected as a push-pull transmission such as a hydraulic cylinder or a pneumatic cylinder. The pressure welding port 14 corresponds to the position where the object to be welded needs to be welded one by one. Shapes such as elliptical cylinders can be used instead.

In this embodiment, the object to be welded needs to be put into the mold body 11 first, and the adjusting bolt 24 needs to be adjusted. The interval between the transmission plate 22 and the pressure plate 23 can be changed by the rotation of the switch, so that it can be adjusted to the required distance, and the knob switch 21 can be turned. to the transmission plate 22, and continue to push the transmission plate 22 to slide in the direction of the object to be welded in the chute. Since the transmission plate 22 and the pressure plate 23 are fixed by the adjusting bolts 24, the pressure plate 23 is pushed to slide in the chute and Reach the object to be welded, and accurately clamp and fix the object to be welded in the mold body 11, then the transmission device 12 is energized and starts to work, push the pressure welding device 13 to the surface of the object to be welded, and the pressure welding port 14 to be welded. Carry out the welding operation. After the welding is finished, turn the knob switch 21 to make the rotating block 26 separate from the transmission plate 22.
