Problems solved by technology
[0003] The welding quality of the car seat is high. The wall plate of the seat pan welding assembly is provided with mounting holes connected with the corresponding components. After the seat pan welding assembly is assembled, in order to ensure normal assembly and installation with other parts of the car seat Precision, high requirements on the position of the mounting holes, if the level of welding technology is low, it often leads to a high failure rate of the product, affecting production efficiency and product quality
Among them, the welding quality requirements of the intermediate connection assembly of the automobile seat pan are relatively high, and the existing technology is difficult to meet the quality requirements

The invention discloses an automobile sitting basin middle connecting assembly welding fixture and welding method. The fixture comprises a base (1), a V-shaped positioning block (2), a positioning pin(3), a first positioning support block (4), a second positioning support block (5), a first hinged support (6), a first connecting rod (29), a first compression rod (7), a first cylinder (8), a second hinged support (9), a second connecting rod (30), a second compression rod (10), a second cylinder (11), a third cylinder (12), a third compression rod (13), a fourth cylinder (14), a fourth compression rod (15), a first positioning seat (16), a first positioning rod (17), a fifth cylinder (18), a sixth cylinder (19), a fifth compression rod (20), a second positioning seat (21), a second positioning rod (22), a seventh cylinder (23), an eighth cylinder (24) and a sixth compression rod (25). The welding process includes the steps: placing a connecting pipe (26) into the V-shaped positioning block (2), the first positioning support block (4) and the second positioning support block (5), and enabling the positioning pin (3) to penetrate a positioning machining hole of the connecting pipe (26); operating all the cylinders to position and compress a first welding part (27) and a second welding part (28).
Description
technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a fixture and a welding method for welding an intermediate connection assembly of an automobile seat pan. Background technique [0002] In recent years, the number of automobiles in my country has increased year by year, and the number of deaths in domestic traffic accidents has shown a downward trend. One of the most important reasons is the development of automobile safety technology. For example, auxiliary systems such as intelligent braking and ESP in active safety can reduce the occurrence of accidents. In terms of passive safety, the steel frame structure of the body and airbags can effectively reduce personal injuries. In addition to the well-known airbags and seat belts, the safety system of car seats is also an important factor to ensure the safety of drivers and passengers. [0003] The welding quality of the car seat is high. The wall plate of the seat...
