Abstract
The invention discloses a nut fastening auxiliary tool for an automobile spare tire. The nut fastening auxiliary tool comprises a bolt, a fastening auxiliary body and four fastening rods, wherein one end of the bolt, which is corresponding to the head part end of the bolt is connected with the fastening auxiliary body in center of one surface of the fastening auxiliary body; one ends of the four fastening rods are arranged on the other surface of the fastening auxiliary body; the other ends of the four fastening rods are corresponding to four corners formed by crossed convex ribs on a spare tire nut body. When a spare tire fastening nut is mounted on the spare tire, unarmed rotating and twisting are not required to carry out by operating workers, a pneumatic wrench is adopted through the fastening auxiliary tool to fasten the spare tire nut, the tightening torque M of the pneumatic wrench is controlled in range of 5 plus and minus 1 Nm, so that the uniformity and reliability of the spare tire fastening nut are guaranteed.
Description
Technical field
The present invention relates to the automobile assembling technical field, especially relate to a kind of automobile spare tire fastening nuts accessory.
Background technology
Automobile spare tire is spare part important on automobile, and the parts that more are absolutely necessary on car, Main Function are when automobile tire breaks down under steam, carry out re-type, can solve the problem that automobile can not travel temporarily.
Spare tyre in car is by using the shank of bolt that stretches out on the spare tyre nut to match with the vehicle body installing hole, spare tyre is fixed on vehicle body, it is extremely important that it is mounted with reliability, when the spare tyre nut stretches out shank of bolt and coordinates with the vehicle body installing hole, operative employee's staff is pinned free-hand the screwing of cross raised ribs on the spare tyre nut, spare tyre fastening nuts moment uniformity is poor, in case the spare tyre fastening nuts is bad, vehicle is crossed the problem that the rear deck abnormal sound will appear in the road of jolting.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of automobile spare tire fastening nuts accessory, and its spare tyre fastening nuts high conformity is fixing reliable.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of automobile spare tire fastening nuts accessory, comprise bolt, fastening accessory body, anchorage bar, the head other end of described bolt simultaneously is connected the center with fastening accessory body, described anchorage bar is four, one end of four anchorage bars all is located on fastening accessory body another side, and four corners that on the other end of four anchorage bars and spare tyre nut body, the cross raised ribs forms are corresponding.
Described four anchorage bar one ends all are located on the same circumference in fastening accessory body center.
Described fastening accessory body is the rosette structure.
Described anchorage bar is shank of bolt, and the head of shank of bolt is welded on fastening accessory body.
Described four anchorage bars are distributed on same circumference with the four points of connection that fastening accessory body is connected.
The edge, head the other end of described anchorage bar is rounded down.
The head of described bolt is hexagonal structure.
The present invention compared with prior art, have the following advantages: when spare tyre is installed the fastening spare tire nut, need not that the operator is free-hand to screw, utilize pneumatic impact spanner to carry out fastening operation to the spare tyre nut by fastening accessory, the pneumatic impact spanner Tightening moment is controlled in M=5 ± 1Nm scope, has guaranteed uniformity and the reliability of spare tyre fastening nuts.
Description of drawings
The below is briefly described the expressed content of each width accompanying drawing of this specification and the mark in figure:
Fig. 1 is the fastening accessory organigram of the present invention.
Fig. 2 is the upward view of Fig. 1.
