There are many types of auto parts, including but not limited to engine parts, transmission system parts, brake system parts, steering system parts, running system parts and ignition system parts, etc.

[0003] In the production process of automotive parts, welding fixtures are generally required for clamping and positioning. The existing welding fixtures can ensure the welding accuracy of the workpiece and stabilize the product quality.

[0004] However, most of the existing welding fixtures are special-purpose. One type of automotive part corresponds to one welding fixture. They have low versatility and cannot be applied to automotive parts of different sizes and types. As a result, when different automotive parts need to be welded, workers need to constantly change them, which seriously affects the welding effect and efficiency of automotive parts. Therefore, an automotive parts welding fixture is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1 , an automobile parts welding fixture in this embodiment includes a workbench 1 and a base plate 2, and a clamping mechanism is provided on the inner side of the workbench 1;

[0025] The clamping mechanism includes a first mounting frame 3 and a second mounting frame 4 fixedly connected to the inner side of the workbench 1, a threaded rod 5 and a rotating shaft 6 are rotatably installed on the inner sides of the first mounting frame 3 and the second mounting frame 4, a driving motor 7 is fixedly connected to the bottom of the first mounting frame 3 and the second mounting frame 4, a first gear 8 is installed on the outside of the rotating shaft 6, a second gear 9 is installed on the outside of the threaded rod 5, a threaded sleeve 10 is threadedly connected to the top of the threaded rod 5, a clamping plate 11 is fixedly connected to the top of the threaded sleeve 10, a sleeve rod 12 and a spring 13 are fixedly connected to the inner sides of the first mounting frame 3 and the second mounting frame 4, and a first gear 8 is installed on the outside of the rotating shaft 6, a second gear 9 is installed on the outside of the threaded rod 5, a threaded sleeve 10 is threadedly connected to the top of the threaded sleeve 10, and a clamping plate 11 is fixedly connected to the top of the threaded sleeve 10. A pressure plate 14 is fixedly connected to the outer surface. When in use, the staff first needs to place the two auto parts on the top of the workbench 1 in turn and align their welding surfaces. Then, start the drive motor 7 to drive the rotating shaft 6 to rotate clockwise. When the rotating shaft 6 rotates clockwise, it can drive the threaded rod 5 to rotate counterclockwise through the meshing transmission of the first gear 8 and the second gear 9. At this time, the threaded sleeve 10 will drive the clamping plate 11 to move downward continuously, and the pressure plate 14 will continuously squeeze the spring 13 downward, so that the clamping plate 11 can clamp and stabilize the two auto parts at the same time, so that the staff can perform welding.

[0026] Among them, the output shaft of the driving motor 7 is fixedly connected to the bottom end of the rotating shaft 6, the first gear 8 is meshed with the second gear 9 for transmission, the pressure plate 14 is slidably connected to the sleeve rod 12, and the bottom of the pressure plate 14 is fixedly connected to the top of the spring 13. By setting the spring 13, automated pressure can be provided to ensure the stability and accuracy of the automotive parts during the welding process. The spring 13 can provide a constant force so that the clamping plate 11 can continuously apply pressure to the workpiece, thereby avoiding loosening of the automotive parts due to external forces or vibrations. In addition, the spring 13 can also absorb impact force, reduce errors caused by vibrations and other reasons, and improve processing accuracy.

[0027] It should be noted that through holes 21 of the same size are formed on the tops of the workbench 1 , the first mounting frame 3 and the second mounting frame 4 , and the threaded sleeve 10 passes through the through holes 21 .

[0028] Embodiment 2:

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 On the basis of the first embodiment, the top of the workbench 1 is fixedly connected with a first box body 15 and a second box body 16 respectively, and the first box body 15 and the second box body 16 are fixedly connected with a first dust collecting fan 17 on one side close to the workbench 1 .

[0030] The interior of the first box body 15 and the second box body 16 are both fixedly connected with the second dust suction fan 18, the inner bottom wall of the first box body 15 and the second box body 16 are both placed with a storage box 19, the front of the first box body 15 and the second box body 16 are both hinged with a sealing door 20, and the outer surface of the sealing door 20 is fixedly connected with an air filter 24. Through the cooperation of the first box body 15, the second box body 16, the first dust suction fan 17, the second dust suction fan 18, the storage box 19 and the air filter 24, harmful gases and dust formed by evaporation or combustion of metal, welding rods, dirt or paint at the welding site due to high temperature during the welding process can be filtered and stored, thereby preventing these harmful substances from causing damage to the human respiratory system and nervous system.

[0031] Before welding, the staff only needs to start the first dust suction fan 17 and the second dust suction fan 18 at the same time to suck the harmful gases and dust generated during welding into the first box body 15 and the second box body 16 respectively, and filter the harmful gases through the air filter 24 before discharging them, while the dust will naturally fall into the storage box 19 for temporary storage until centralized cleaning. It should be noted that the air filter 24 can be an activated carbon filter or a HEPA filter or other types of filters for specific harmful gases.

[0032] In addition, the bottom of the workbench 1 is fixedly connected to the top of the base plate 2, and universal rollers 22 are rotatably connected to the bottom of the base plate 2. A baffle 23 for shielding and dust prevention is fixedly installed on the front of the workbench 1.

[0033] The working principle of the above embodiment is:

[0034] When in use, the staff first needs to place the two auto parts on the top of the workbench 1 in turn, and align their welding surfaces. Then, start the drive motor 7 to drive the rotating shaft 6 to rotate clockwise. When the rotating shaft 6 rotates clockwise, it can be driven by the meshing transmission of the first gear 8 and the second gear 9, thereby driving the threaded rod 5 to rotate counterclockwise. At this time, the threaded sleeve 10 will drive the clamping plate 11 to move downward continuously, and the pressure plate 14 will continuously squeeze the spring 13 downward, so that the clamping plate 11 can clamp and stabilize the two auto parts at the same time, so that the staff can perform welding. When the welding is completed, the output shaft of the drive motor 7 is controlled to rotate counterclockwise to reset the clamping plate 11, thereby quickly releasing the clamping of the auto parts for the staff to unload the materials.

[0035] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role, and the existing public power connection technology is not described in detail in the text.
