Steering wheel temporary fastening jig and method for temporarily fixing steering wheel

Abstract

The invention relates to a steering wheel temporary fastening jig and a method for temporarily fixing a steering wheel. The steering wheel temporary fastening jig comprises a U-shaped body; the U-shaped body comprises a fixing base; fixing claws are arranged on the front end face of the fixing base; the fixing claws comprise a left side fixing claw and a right side fixing claw; each fixing claw comprises a fixing part and an extension part; the lower surface of the fixing part extends from the lower surface of the fixing base; the fixing part is connected with the extension part; and the uppersurface and the lower surface of the fixing part are parallel. The method for temporarily fixing the steering wheel comprises the following steps: the steering wheel is placed on a steering wheel supporting base; a stud used for fastening the steering wheel is placed in a threaded hole of the supporting base; the front end of the stud is preliminarily connected with the threaded hole of the supporting base; and the steering wheel fastening jig is inserted into the outer side of a screw rod at the lower side of the head of the stud. According to the temporary fastening jig for the steering wheel, the gap between the steering wheel and the stud is rapidly eliminated on an automobile assembly production line, the number of used tools is reduced, the steering wheel is conveniently and rapidlyfixed, and the operation time and the tool use cost are saved.

Description

technical field [0001] The invention relates to an installation tool for an automobile assembly line, in particular to a temporary fastening fixture for a steering wheel and a method for temporarily fixing the steering wheel. Background technique [0002] The structure of the combination of the steering wheel and the transformation column of the new model has changed from the original nut to a stud, and the shape has changed. [0003] The original nut can be tightened with a small force by hand, and the steering wheel fastening stud cannot be tightened to the end even with a great force by hand. [0004] There is a gap (about 1 cm) between the steering wheel and the nut. Before the car leaves the factory, the "toe-in" adjustment of the steering wheel and tire angle (adjustment to prevent the vehicle from running off) must be carried out. To carry the vehicle, rotate the steering wheel and adjust the angle Move the vehicle to the equipment. If you move the vehicle without th...

[0003] The original nut can be tightened by hand with a small force, but the steering wheel fastening stud cannot be tightened to the end even with a large force by hand

[0004] There is a gap (about 1 cm) between the steering wheel and the nut. Before the car leaves the factory, the "toe-in" adjustment of the steering wheel and tire angle (adjustment to prevent the vehicle from running off) must be carried out. To carry the vehicle, rotate the steering wheel and adjust the angle Move the vehicle to the equipment. If you move the vehicle without the steering wheel fastened, the coil under the steering wheel will come out and break. Once it goes to the market, there will be many hidden dangers (steering failure, horn not sounding, airbags not working, serious traffic accidents) So it is very important), even if the defect is found in the factory, the cost of replacing a coil will be 500 yuan / unit

[0005] At present, domestic and foreign inspection lines use tool guns to fasten the steering wheel, then loosen the steering wheel in the next process, then adjust the toe-in, and then use another gun to fasten the steering wheel, which is cumbersome
