[0013] Working principle: When welding and repairing damaged auto parts, the staff will first open the opening door on the top seat on one side of the first workstation, and then after it is opened, the staff will place the auto parts to be repaired in the middle of the top of the positioning seat, and then the staff will reset the opened door to prepare for the subsequent welding and repair work; first, the positioning locking mechanism is started, and the driving motor 2 in the positioning seat is started. The rotating shaft of the driving motor 2 drives the driving disk on the limiting stabilizing seat to rotate synchronously. While the driving disk rotates, it also drives the spiral track on it to rotate synchronously. While the spiral track rotates, it also makes The spiral track rotates synchronously in the arc groove on the bottom sliding seat of the step fixing seat. As the spiral track on the driving plate rotates, the driving plate drives the step fixing seat to move synchronously toward the middle in the moving groove of the positioning seat. As the step fixing seat in the moving groove moves synchronously toward the middle, the damaged automobile parts on the positioning seat are also pushed to move synchronously toward and approach the middle during the movement of the step fixing seat. After the step fixing seat positions the automobile parts on the positioning seat at the center position of the positioning seat, the step fixing seat stops moving, thereby completing the center positioning and clamping and fixing of the damaged automobile parts on the positioning seat. After the step fixing seat has positioned and fixed the damaged automobile parts on the positioning seat, the step fixing seat stops moving in the moving groove on the positioning seat. At this time, the electromagnet seat 1 in the inner cavity is energized, thereby changing the magnetism of the electromagnet seat 1 and the electromagnet seat 2, so that the magnetism of the electromagnet seat 1 and the locking socket are the same, and the magnetism of the electromagnet seat 2 and the locking socket are opposite. According to the principle that like magnets repel each other and opposite magnets attract each other, the same repulsive force generated between the electromagnet seat 1 and the locking socket causes the locking socket in the inner cavity to slide down into the bottom cavity on the driving disk, and is locked by the magnetic attraction between the electromagnet seat 2 in the bottom cavity and the locking socket. Adsorption and fixation are performed, so that the driving disk, the positioning seat and the damaged automobile parts thereon are locked after the positioning is completed, so as to improve the fixing stability of the damaged automobile parts during subsequent processing. After the automobile parts on the positioning seat are positioned and locked, the electric slide rail seat at the bottom of the moving seat is started. When the electric slide rail seat is started, the moving seat, the positioning seat and the automobile parts that are positioned and locked are driven to move on the slotted moving track, so that the automobile parts after the movement arrive at the second station position on the base, so as to complete the positioning and locking of the damaged automobile parts;When the automobile parts to be positioned and locked arrive at the second workstation on the base, the preheating elimination mechanism is started, and the staff controls the electric cylinder 1 in the processing chamber to start through the control device. When the electric cylinder 1 is started, the rod body on it is pushed out, and then the mounting cover 2 at the bottom is moved down synchronously while the rod body of the electric cylinder 1 is pushed out, so that the mounting cover 2 after moving down can insert the automobile parts that are positioned and fixed on the positioning seat, and then the preheating gun on the heat-insulating air supply ring seat is started and sprays flames to heat and preheat the automobile parts fixed on the positioning seat, and at the same time, the driving motor 1 in the moving seat is started synchronously, and the driving motor 1 simultaneously drives the positioning seat and automobile parts on it to start. Rotate, thereby ensuring the uniformity of automobile parts during the preheating process, and the stress in the automobile parts can also be eliminated during the heating process, so as to complete the preheating and stress elimination treatment of the automobile parts before welding; then after the preheating elimination mechanism has completed the preheating treatment of the automobile parts, the electric slide seat in the moving track is started again to drive the moving seat, the positioning seat and the automobile parts on it that have completed the preheating treatment to move to the third station position on the base, and then the fracture grinding mechanism is started. First, the staff controls the electric cylinder 2 in the processing chamber through the control equipment to start. After the electric cylinder 2 is started, the rod body on it is pushed out, and the rod body on the electric cylinder 2 is pushed out while driving the installation The cover 1 moves downward synchronously, so that the installation cover 1 after moving downward can insert the automobile parts on the positioning seat of the third station, and at the same time make the fluffy cotton seat and the frosted layer at the bottom of the rotating seat contact with the fracture position of the automobile parts and produce corresponding deformation, and then the driving motor 3 on the supporting seat is started, and the rotating shaft of the driving motor 3 drives the rotating seat at the bottom of the supporting seat to rotate synchronously while rotating, and the rotating seat drives the fluffy cotton seat at the bottom and the frosted layer thereon to rotate synchronously while rotating, and the frosted layer on the fluffy cotton seat grinds the fracture position of the automobile parts on the positioning seat while rotating, so as to complete the grinding process of the fracture position of the automobile parts before welding; then the fracture grinding mechanism grinds the automobile parts After the grinding process is completed at the fracture position, the electric slide rail seat in the moving track is started again to drive the moving seat, the positioning seat and the automobile parts on it that have been polished to move to the fourth station position on the base, and then the automatic welding mechanism is started.

[0014] The present invention provides a multi-directional adjustable automobile parts welding and repair equipment, which has the following beneficial effects: 1. The present invention adds and sets a positioning locking mechanism to perform center positioning and fixed locking treatment on damaged automobile parts before welding and repair. First, the fixing and locking can keep the damaged automobile parts in the correct position during the welding process, ensuring their stability during the welding process. Secondly, a large amount of heat will be generated during the welding process, which may cause the parts to deform. By fixing and locking them, the thermal deformation of the parts can be limited and their original shape can be maintained. Finally, by fixing and locking, the parts can be adjusted to the correct position at one time before welding, reducing the adjustment time during the welding process, improving the welding efficiency and facilitating the subsequent automated welding process.

[0015] 2. The present invention adds and sets a parts preheating mechanism to preheat the damaged automobile parts before welding and repairing them. This can not only reduce the cooling rate of automobile parts during welding, thereby reducing or eliminating the generation of stress during welding and repair, but also help prevent the occurrence of cracks during welding and repair. In addition, preheating automobile parts before welding and repair can also allow the weld metal to have enough time to crystallize and phase change during the solidification process, thereby forming a more uniform and dense weld structure, thereby improving the strength, toughness and corrosion resistance of the weld, and at the same time can also reduce the generation of defects such as pores and slag inclusions in welding, thereby improving the quality of the overall welding of automobile parts.

[0016] 3. The present invention adds and sets a parts preheating mechanism to preheat the damaged automobile parts before welding and repairing them. On the one hand, it can make the temperature of the welding area more uniform and reduce the temperature fluctuation during welding, which is helpful to stabilize the welding arc and improve the stability of welding quality. On the other hand, it can also make the metal in the welding area easier to melt and flow, reduce the difficulty of welding, and improve the welding and repair efficiency of automobile parts. At the same time, it can also reduce spatter and smoke during welding, thereby improving the welding working environment.

[0017] 4. The present invention adds and sets a parts preheating mechanism to preheat the damaged automobile parts before welding and repairing them. Firstly, the heat input in the welding process can be reduced, thereby reducing the width and hardness of the heat-affected zone. This treatment method helps to protect the parent material properties of automobile parts and avoid problems such as reduced strength and increased brittleness caused by welding. Secondly, preheating can make the temperature of the welding area more uniform, reduce deformation and stress concentration in the welding process, thereby helping to prevent problems such as deformation and cracking of automobile parts after welding, and improve the dimensional accuracy and service life of parts.

[0018] 5. The present invention increases and sets a fracture grinding mechanism, and grinds the fracture position of the automobile parts after preheating treatment before welding. This can not only remove impurities such as dirt, rust, and oil stains at the fracture, ensure the cleanliness of the welding area, thereby ensuring the strength and sealing of the weld at the fracture, but also remove the oxide layer and corrosion layer on the fracture surface and improve the shape of the fracture, so that fresh metal is exposed at the fracture and the fracture is more regular, which is beneficial to the fusion of the weld metal and the base material and improves the quality of the welded joint. In addition, grinding can make the transition at the fracture smoother, reduce the stress concentration at the fracture, and reduce the stress concentration coefficient at the fracture, thereby improving the fatigue life of the welded joint.

[0019] 6. The present invention increases and sets an automatic welding mechanism to automatically weld automobile parts after the fracture grinding process. On the one hand, it can reduce the labor intensity of the workers and at the same time avoid the smoke generated during the welding process from affecting the workers. On the other hand, it can also improve the operational safety during the welding process. While ensuring the welding efficiency, the operational safety and automation level are also higher.
