DETAILED DESCRIPTION

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

[0022] Example 1: Reference Figure 1-Figure 4 As shown: A positioning mechanism for automobile parts processing and welding, including a mounting frame 1, a plurality of positioning components 2 are fixedly installed on one side of the mounting frame 1, a rotating component 3 is arranged on the other side of the mounting frame 1, the positioning component 2 includes a mounting base 21, a supporting base 22, a quick clamp 23 and a supporting bottom plate 24, the quick clamp 23 is fixedly installed above the mounting base 21, the supporting bottom plate 24 is fixedly installed above the supporting base 22, the supporting base 22 is arranged on one side of the mounting base 21, and a preheating groove 241 is opened inside the supporting bottom plate 24, and the inside of the preheating groove 241 A heat conducting plate 242 is fixedly connected, and an electric heating rod 25 is fixedly installed on the other side of the supporting base plate 24. A heat conducting layer 251 is sleeved on the outer side of the electric heating rod 25. The heat conducting layer 251 is made of heat conducting epoxy resin. The heat conducting layer 251 is arranged inside the preheating groove 241, and one side of the heat conducting layer 251 is attached to one side of the heat conducting plate 242. The mounting base 21 and the supporting base 22 are both fixedly installed on one side of the mounting frame 1 by bolts. The heat conducting plate 242 is made of copper-based graphite composite material. One side of the clamping block in the quick clamp 23 is fixedly connected to the automotive component positioning block 231 by bolts.

[0023] In this embodiment, in the preparation work for welding automobile parts, the automobile parts to be welded must first be properly placed on the supporting base plate 24, and then the quick clamp 23 must be accurately adjusted so that the automobile parts positioning block 231 on the quick clamp 23 is accurately engaged with one side of the automobile parts. Through the synergistic effect of the automobile parts positioning block 231 and the supporting base plate 24, the two are closely matched to stably clamp the automobile parts. This stable clamping process is crucial for subsequent welding operations. It ensures that the automobile parts will not be displaced unnecessarily during the welding process, laying the foundation for high-quality welding. Next, the electric heating rod 25 is started, and the electric heating rod 25 starts to work and generate heat energy. These heat energies will be transferred to the inside of the heat-conducting layer 251 and the heat-conducting plate 242 in turn through the principle of heat transfer. The heat-conducting layer 251 plays a key role as a heat transfer bridge in this process. It is made of heat-conducting epoxy resin, which has unique performance advantages. It not only has high strength and hardness, but also can maintain the stability of its own structure in the process of heat transfer, and also has a certain heat conductivity. This material can effectively receive and transfer the heat generated by the electric heating rod 25, reducing the loss of heat in the process of transfer; the heat-conducting plate 242 is made of copper-based graphite composite material, which performs well in heat conduction. The copper-based graphite composite material can quickly conduct heat, and its efficient heat conduction performance enables it to be used as an excellent heat-conducting medium, quickly transferring the heat transferred from the heat-conducting layer 251 to the inside of the automotive parts, and realizing efficient preheating and heating of the automotive parts; through such a preheating process, during welding, the automotive parts can be evenly heated, and no thermal deformation will occur due to uneven local heating. This ensures that the relative positions of the auto parts remain stable, avoiding gaps in the welds due to deformation of the parts during the subsequent welding process. This effectively ensures the stability of the weld, provides reliable protection for the welding quality of auto parts, and further improves the overall manufacturing quality and safety of the car.

[0025] In this embodiment, the automobile component positioning block 231 is made of silicon nitride ceramics. The thermal expansion coefficient of silicon nitride ceramics is small, and its crystal structure has high stability at high temperature, which makes it have good resistance to thermal deformation. During the preheating and welding process of automobile components, silicon nitride ceramics give the automobile component positioning block 231 excellent performance. Specifically, the automobile component positioning block 231 will not experience thermal deformation, so that the quick clamp 23 can stably clamp the automobile component, thereby improving the stability of the positioning mechanism for automobile component processing and welding in positioning and clamping the automobile component. The clamping stability plays an indispensable role in ensuring the welding quality, dimensional accuracy and overall performance of automobile components, and provides a strong guarantee for high-quality production in the automobile manufacturing process.
