Description of the embodiments
The utility model will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides an airbag nut tightening device, which comprises a tightening shaft, a sleeve and an elastic element, wherein the lower end of the tightening shaft 9 is exposed out of a shell 4, the end part of the tightening shaft 9 is sleeved with the sleeve 8, the lower end of the tightening shaft 9 is sleeved with the elastic element, two ends of the elastic element respectively prop against the bottom end face of the shell 4 and the top end face of the sleeve 8, and the lower end of the sleeve 8 props against an airbag nut 7.
The bottom of the shell 4 and the top of the sleeve 8 are respectively provided with a shaft sleeve 5, and the two ends of the elastic element respectively prop against the shaft sleeve 5. The edge of the shaft sleeve 5 is provided with a profiling structure, and the profiling structure is coated at the outer diameter end part of the elastic element.
During the tightening of the airbag nut 7, rotation of the sleeve 8 will drive the spring element to move radially left and right. The profiling structure of the edge of the sleeve 5 can prevent the elastic element from radial play on the tightening shaft 9 to a great extent, so that the stability of the elastic element when the elastic element applies reverse acting force in the tightening process of the airbag nut 7 is ensured.
The resilient element is typically a spring 6. The strength of the spring 6 is matched with the specification and the friction coefficient of the air bag nut 7, and the strength of the spring 6 can be adjusted according to the specification and the friction coefficient of the air bag nut 7 so as to adjust the down force in the screwing process.
Referring to fig. 2 and 4, the tightening shaft 9 and the housing 4 are mounted on the mount 1 of the automatic nut driving device. The mounting seat 1 is driven by a lifting cylinder 11 and an XY axis servo 10 to realize lifting and moving. A tooling mould 12 is arranged below the tightening shaft 9, an airbag with a bolt column 2 is placed on the tooling mould 12, and the tightening shaft 9 corresponds to the bolt column 2 up and down. The mounting seat 1 is provided with a positioning step 3 to realize positioning when the tightening device is mounted.
The present utility model can be used for the assembly of the driver airbag DAB, the passenger airbag PAB, the side airbag SAB, the knee airbag KAB.
Referring to fig. 3, when the automatic nut driving device drives the tightening shaft 9 to press down, compression is formed on the spring 6, and the compressed spring 6 is gradually released during the tightening process of the airbag nut 7 and the bolt stud 2. The reverse acting force released by the spring 6 is transmitted to the air bag nut 7 through the sleeve 8, so that the air bag nut 7 is ensured not to deviate from the sleeve 8 in the tightening process of the air bag nut 7 and the bolt post 2, and the downward pressure F is always generated, so that the air bag nut 7 is tightly matched with the sleeve 8.
