Abstract
The utility model discloses a screw bolt for fixing a transmission shaft and an automobile body of an automobile, which has the advantages that a screw nut and a screw rod of the screw bolt can be accurately led and screwed during mechanical hand assembly. The screw bolt comprises a head (1), a screw rod (6) and a section of post body (5), wherein the post body (5) is arranged between the head (1) and the screw rod (6) and is used for being tightly matched with the transmission shaft of the automobile. The end of the screw rod (6) is provided with a section of guide post (7), and the diameter of the guide post (7) is smaller than that of the screw rod (6).
Description
Technical field
The utility model relates to technical field of fastening, specifically is a kind of transmission shaft of fixed car and the bolt that vehicle body is used.
Background technique
The bolt that the transmission shaft of existing fixed automobile and vehicle body are used comprise head and screw rod and be located at head and screw rod between be used for one section cylinder with the transmission shaft close-fitting of automobile, concrete structure is as shown in Figure 1.The connection part of the transmission shaft of described cylinder and automobile produces plastic deformation because of extruding makes metal, thereby the transmission shaft close-fitting that makes cylinder and automobile together, and described bolt is fixedlyed connected with the transmission shaft of automobile.Then, described bolt connects vehicle body by screw rod (being used nut) again.Like this, described bolt just is fixed together the transmission shaft and the vehicle body of automobile.The bolt that the transmission shaft of described fixed car and vehicle body are used is when assembling automatically with mechanism hand, because the guidance quality of the structure of existing bolt is poor, can not accurately import the situation generation that screws so often have between the screw rod of nut and bolt, cause random tooth takes place between the screw thread of nut and screw flight, even bolt cut off, bring great inconvenience for assembling and dismounting.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of and can accurately import the transmission shaft of the fixed car that screws and the bolt that vehicle body is used between the screw rod of nut and bolt when mechanism hand assembles.
The technical solution of the utility model is, the bolt that the transmission shaft of the utility model fixed car and vehicle body are used, it comprise head and screw rod and be located at head and screw rod between be used for one section cylinder with the transmission shaft close-fitting of automobile, the end of described screw rod is provided with one section directional post, the diameter of this directional post less than screw rod diameter.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the end of described screw rod is provided with one section directional post,, the diameter of this directional post less than screw rod diameter, so when mechanism hand assembles, can accurately import between the screw rod of nut and bolt and screw, improved efficiency of assembling, between the screw thread of minimizing nut and screw flight because importing angle can not finely overlap, and causes described screw thread to screw the random tooth of inconsistent generation or the situation of cutting off bolt.
As improvement, the excircle of described cylinder 5 is provided with straight knurling, and like this, the transmission shaft of described cylinder and automobile close-fitting better more helps the raising of the utility model performance together.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the bolt that the transmission shaft of prior art fixed car and vehicle body are used, chamfered has just been carried out in the end of its screw rod 6.
The bolt that the transmission shaft of the utility model fixed car and vehicle body are used, it comprise head 1 and screw rod 6 and be located at head 1 and screw rod 6 between be used for one section cylinder 5 with the transmission shaft close-fitting of automobile, the end of described screw rod 6 is provided with one section directional post 7, the diameter of this directional post 7 less than screw rod 6 diameter, concrete structure is as shown in Figure 2.
The excircle of described cylinder 5 is provided with straight knurling, can realize by existing annular knurl technology.
For ease of understanding, the structural representation of the transmission shaft of enclosing automobile and connection part after vehicle body is connected, it comprises the part and the nut 2 of transmission shaft 4 of part, the automobile of the transmission shaft of fixed car and bolt that vehicle body is used, vehicle body 3, and concrete structure as shown in Figure 3.
Claims (2)
1. the bolt used of the transmission shaft of a fixed car and vehicle body, it comprise head (1) and screw rod (6) and be located at head (1) and screw rod (6) between be used for one section cylinder (5) with the transmission shaft close-fitting of automobile, it is characterized in that, the end of described screw rod (6) is provided with one section directional post (7), the diameter of this directional post (7) less than screw rod (6) diameter.
2. the bolt used of the transmission shaft of fixed car according to claim 1 and vehicle body is characterized in that the excircle of described cylinder (5) is provided with straight knurling.
