The connection bolt of the automobile bond strap, disclosed by the utility model, has the advantages of simple structure, strong practicability, high production efficiency and low industrial cost.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of automobile ground strap connecting bolt.
Background technique
Automobile industry mainly comprises punching press, is welded when manufacturing, application, general assembly four procedures; In the general assembly operation; Being used to connect automotive wire bundle minus earth line and vehicle body link commonly used is the conventional hexagonal-head bolt; But because of the general assembly operation is positioned at after the coating process; Paint behind the coating process accumulates in mounting hole easily, and needs under the fastening situation of nut in the bolt installation, with the also easy adhesion that produces paint of the welded nut of bolton; When this caused bonding bolt is installed, the paint powder can't in time be got rid of and overstock at the bolt head place along the lines of bolt thread section, very easily causes the bad phenomenon of minus earth; Accomplish when powering on debugging in vehicle assembling at last, produce the situation of electric equipment unknown cause fault in the car, and various, cause to be difficult to the problem that finds impact point, manufacturing efficiency step-down, cost to increase the weight of because of the bonding tie point.
In the existing technology,, often adopt following manner for addressing the above problem:
The first, after the installation bonding bolt finishes, detect the reliability that connects with corresponding instrument immediately; But do not enhance productivity, be unfavorable for on-the-spot executable operations yet;
The second, after the paint spraying in mounting hole zone is arranged on bonding bolt and installs, but this make manufacturing step just more complicated, and be unfavorable for process optimization;
The 3rd, before coating process in mounting hole the mounting process bolt, treat that application finishes after, when the general assembly operation, it is back-outed again, reinstall with bonding bolt, but the method wastes time and energy, and consumes a large amount of service bolts, increased cost of production.
Summary of the invention
The utility model provides a kind of automobile bonding connecting bolt, has solved the automobile bonding because the paint powder overstocks the problem that causes the ground strap bad connection.
A kind of automobile ground strap connecting bolt comprises bolt body, and described bolt body is generally selected conventional hexagon head bolt for use; The front portion of described bolt body is a thread section, and described thread section is provided with a scraping groove longitudinally, and said scraping groove communicates with the end of said thread section; The bottom land of described scraping groove slope inwardly along the end of thread section to thread surface for best.
As preferably, can be provided with a material-storing groove on the described scraping groove lower thread section, described material-storing groove can be square groove, the notch direction of scraping groove and material-storing groove is opposing to be best; Described scraping groove makes bolt preliminary when urgent, and the part paint powder that utilizes the eccentric leading role of groove bottom to produce is derived thread pitch through this bottom surface, to reduce overstocking of paint powder; And the turn effect through screw thread, residual paint powder is directed in the described material-storing groove, prevents to paint powder and gets into the bolt bottom and then cause the situation of bad earth to occur.
Plain washer can also be provided with on the foot piece section at described bolt body rear portion, also spring washer can be provided with on this basis again; One end of said spring washer and the head of said bolt body offset, and the other end and described plain washer offset; The tensioner effect of said spring washer can guarantee ground strap and said bolted tightness, utilizes plain washer then can increase ground strap area of contact with it, improves the line conduction rate.
Need use under the situation of nut in the installation of bolt, described foot piece section can be interference fit with needing fastening nut, helps removing the paint that adheres on the nut, improves the electric conductivity of bolt.
During use, the head of ground strap is put between plain washer and the spring washer, then bolt is mounted in the mounting hole; Under the situation that needs nut to install, that bolt is through behind the mounting hole, fastening with nut.In this process, scrape the lacquer effect and material-storing groove further stores up the lacquer effect through the scraping groove, improved the electric conductivity of ground strap connecting bolt.The utility model is simple in structure, and is practical, improved manufacturing efficiency, reduced industrial cost.
Description of drawings
Fig. 1 is the structural representation of a kind of automobile ground strap of the utility model connecting bolt;
Fig. 2 is the rear view of Fig. 1.
Embodiment
Introduce a kind of embodiment of the utility model in detail below in conjunction with accompanying drawing.As depicted in figs. 1 and 2, a kind of automobile ground strap connecting bolt comprises bolt body 1, and bolt body 1 is a hexagon head bolt; The front portion of bolt body 1 is a thread section 2, and thread section 2 is provided with a scraping groove 3 longitudinally; The bottom land of scraping groove 3 slopes inwardly to thread surface along the end of thread section 2, and scraping groove 3 lower thread sections 2 are provided with a material-storing groove 4; The notch direction of scraping groove 3 and material-storing groove 4 is opposing; The foot piece section 5 at bolt body 1 rear portion is provided with plain washer 6 and spring washer 7, and an end of spring washer 7 and the head of bolt body 1 offset, and the other end and described plain washer 6 offset.
The specific operation process of the utility model is:
The head of ground strap is put between plain washer 6 and the spring washer 7, then bolt is mounted in the mounting hole; When the installation of bonding bolt need be used under the situation of nut, that bolt is through behind the mounting hole, fastening with nut.
In said process, scraping groove 3 makes bolt preliminary when urgent, utilizes part paint powder that the eccentric leading role of groove bottom will produce to derive the thread pitch of mounting hole or nut through this bottom surface, to reduce overstocking of paint powder; And the turn effect through screw thread, residual paint powder is directed in the material-storing groove 4, prevents to paint powder and gets into the bolt bottom and then cause the situation of bad earth to occur.
Though described the mode of execution of the utility model in conjunction with accompanying drawing, those of ordinary skills can make various changes or modification within the scope of the appended claims.
