[0026] As a preferred embodiment; an air valve switch 7 is further arranged on the top surface of the workbench 1, the air valve switch 7 is connected to the driving device 5 through an air pipe, and the driving device 5 is a cylinder; it can be understood that an air valve switch 7 is provided in this application, and the air valve switch 7 can respectively control the two driving devices 5 of the double station to enable them to work synchronously.

[0027] As a preferred embodiment, an installation seat 8 is further provided on the top surface of the workbench 1, and the driving device 5 is fixedly connected to the installation seat 8 through a connecting plate 9. By providing the installation seat 8, not only can the driving device 5 (the driving device 5 is arranged on one side of the loading platform 2) be fixedly connected, but also the loading platform 2 can be installed, facilitating the clamping of the automotive parts 19 and the threaded pipe 20.

[0028] As a preferred embodiment, the fixing mechanism 3 further includes a first connecting block 10, a second connecting block 11, a third connecting block 12, a fourth connecting block 13, and a fifth connecting block 14. The first connecting block 10 is fixedly connected to the connecting plate 9. The push rod end of the driving device 5 is connected to a second connecting block 11. The second connecting block 11 is hinged to a third connecting block 12. The other end of the third connecting block 12 is fixedly connected to a fourth connecting block 13. A plug 6 is installed at the other end of the fourth connecting block 13. The middle of the fourth connecting block 13 is also hinged to a fifth connecting block 14, and the other end of the fifth connecting block 14 is hinged to the first connecting block 10. It can be understood that with the first connecting block 10, the second connecting block 11, the third connecting block 12, the fourth connecting block 13, and the fifth connecting block 14 provided, under the drive of the driving device 5, the third connecting block 12 and the fifth connecting block 14 can rotate, and thus the plug 6 can be lifted or pressed down in a circular motion. This not only reduces the occupied area during the structural movement trajectory process, but also enables the plug 6 to more precisely land on the threaded pipe 20, and at the same time has a strong tightening force, capable of effectively tightening and fixing the automotive parts 19 and the threaded pipe 20.

[0029] As a preferred embodiment, the positioning column 4 is installed on the installation seat 8. The loading platform 2 further includes a first mounting block 15 and a second mounting block 16. The first mounting block 15 and the second mounting block 16 are symmetrically arranged left and right. The opposite surfaces of the first mounting block 15 and the second mounting block 16 are both inclined. The positioning column 4 is installed between the first mounting block 15 and the second mounting block 16. By providing the first mounting block 15 and the second mounting block 16, their inclined surfaces can effectively abut against the automotive parts 19, reducing the connection gap and improving the effect after tightening.

[0030] As a preferred embodiment, a positioning pin 17 is further installed on the top surface of the installation seat 8. By providing the positioning pin 17, the positioning pin 17 is inserted into the automotive parts 19, which can prevent the displacement of the outer edge part of the automotive parts 19 and enable more precise installation of the automotive parts 19.

[0031] As a preferred embodiment, an inner connecting ring 18 is further installed inside the plug 6, and the inside of the inner connecting ring 18 is a hollow structure; by providing the inner connecting ring 18, the end face of the plug 6 abuts against the end face of the threaded pipe 20, and the positioning post 4 will be exposed outside the plug 6. After the plug 6 abuts against the threaded pipe 20, the positioning post 4 can extend into the inside of the inner connecting ring 18 (equivalent to the inner connecting ring 18 being sleeved with the positioning post 4. After this part is sleeved, the end face of the plug 6 can accurately correspond to the end face of the threaded pipe 20), which can effectively prevent the plug 6 from moving out of position, further enhance the fixing effect (the contact area is increased), and can better weld the automotive part 19 and the threaded pipe 20 (there is no protruding part blocking the welding position).

[0032] The working principle of the present utility model is as follows: First, place the automotive part 19 on the loading platform 2 (a through hole is provided on the automotive part 19 and is inserted into the positioning post 4). The first mounting block 15 and the second mounting block 16 of the loading platform 2 can abut against the automotive part 19. Then place the threaded pipe 20, which is also inserted into the positioning post 4. At this time, turn the handle of the air valve switch 7 to open the air circuit of the driving device 5. After the driving device 5 is started, it will drive the second connecting block 11 to move upward, causing the third connecting block 12 and the fifth connecting block 14 to move downward in a circular motion, and then causing the plug 6 to move in a circular motion and press down on the end face of the threaded pipe 20. At this time, the plug 6 can block the opening of the threaded pipe 20, and effectively fix the automotive part 19 and the threaded pipe 20 under the action of pressure; after the automotive part 19 and the threaded pipe 20 are fixed, the welding mechanism can be driven by an external six-axis manipulator to weld the outer edge of the threaded pipe 20 and the inner side surface of the automotive part 19.

[0033] It should be pointed out that the main problems in the prior art are as follows: When welding the automotive part and the threaded pipe, manual operation is generally used. Manual welding not only has a high labor cost, but also reduces the efficiency. In addition, since the inside of the threaded pipe is a hollow structure, the welding debris is likely to enter the inside of the threaded pipe, which greatly affects the welding quality of the automotive part;

[0034] Therefore, after the improvement of this application, the present utility model changes the deficiency of using manual welding operation, reduces the labor cost, improves the production efficiency, reduces the safety hazards. At the same time, this fixture not only replaces the operation of manually fixing the threaded pipe 20 and the automotive part 19, but also can block the opening of the plug 6, thereby greatly improving the welding quality of the threaded pipe 20 and the automotive part 19.

[0035] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
