Abstract
The utility model discloses a dislocation connecting bolt mechanism belongs to the technical field of whole car assembly, accumulative total error when solving power assembly right side suspension assembly and the right front longitudinal beam welding assembly of automobile body, lead to the problem that the bolt hole installation dislocation can't be installed, this mechanism is screwed up positioning bolt by two belows, the dislocation connecting block, two tops are screwed up positioning stud and two stud and are screwed up the nut and constitute, under the condition in two holes of various spaces dislocation, as long as thickness direction size is enough, all can realize the bolted connection installation that misplaces, high efficiency, strong flexibility, the cycle is short. The problem that the right suspension assembly and the right front longitudinal beam welding assembly cannot be connected and assembled through bolts is effectively solved.
Description
Technical Field
The utility model belongs to the technical field of whole car assembly.
Background
When the power assembly right suspension assembly is assembled with the vehicle body right front longitudinal beam welding assembly, due to the fact that the installation bolt hole of the right suspension assembly and the installation hole of the right front longitudinal beam welding assembly are staggered in space, errors can be accumulated frequently due to the influence of a closed ring of a size chain when the whole vehicle is assembled in a trial mode, and bolt hole installation is staggered. At present, in the prior art, the connection work of two holes with staggered space is solved by changing the position of a hole position of a part, so that the flexibility is poor, the efficiency is low, the period is long, and the cost is high.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model provides a staggered connecting bolt mechanism, which comprises two lower tightening positioning bolts, a staggered connecting block, two upper tightening positioning studs and two stud tightening nuts,
threaded through holes are formed in two ends of the staggered connecting block, the two lower tightening positioning bolts are respectively installed in the two threaded through holes in the staggered connecting block, and the positions of the threaded through holes correspond to the positions of the openings in the longitudinal frame assembly of the vehicle body; two counter bores are formed in the middle of the staggered connecting block, and two upper tightening positioning stud bolts are respectively installed and fixed in the two counter bores; the position of the upper screwing positioning stud corresponds to the openings on the right suspension and the left suspension of the power assembly; two stud tightening nuts are arranged on the upper tightening positioning studs and used for connecting and fixing the power assembly right suspension and the power assembly left suspension with the staggered connecting block.
The utility model has the advantages that:
under the condition of two holes staggered in various spaces, as long as the size in the thickness direction is enough, staggered bolt connection installation can be realized, the efficiency is high, the flexibility is strong, and the period is short. The problem that the right suspension assembly and the right front longitudinal beam welding assembly cannot be connected and assembled through bolts is effectively solved.

Detailed Description
The technical solution of the present invention will be further explained and illustrated in the following embodiments.
As shown in figure 1, the dislocation connecting bolt mechanism consists of two lower tightening positioning bolts (a lower tightening positioning bolt I1 and a lower tightening positioning bolt II 2), a dislocation connecting block 3, two upper tightening positioning studs (an upper tightening positioning stud I4 and an upper tightening positioning stud II 5) and two stud tightening nuts (a stud tightening nut I6 and a stud tightening nut II 7),
two ends of the dislocation connecting block 3 are provided with threaded through holes, two lower tightening positioning bolts (a lower tightening positioning bolt I1 and a lower tightening positioning bolt II 2) are respectively arranged in the two threaded through holes on the dislocation connecting block 3, and the positions of the threaded through holes correspond to the openings on the vehicle body longitudinal frame assembly 8; the middle part of the dislocation connecting block 3 is provided with two counter bores, and two upper screwing positioning stud bolts (an upper screwing positioning stud bolt I4 and an upper screwing positioning stud bolt II 5) are respectively installed and fixed in the two counter bores; the positions of two upper tightening positioning studs (an upper tightening positioning stud I4 and an upper tightening positioning stud II 5) correspond to the openings on the power assembly right suspension 9 and the power assembly left suspension 10; two stud tightening nuts (a stud tightening nut I6 and a stud tightening nut II 7) are respectively arranged on two upper tightening positioning studs (an upper tightening positioning stud I4 and an upper tightening positioning stud II 5) and are used for connecting and fixing the power assembly right suspension 9, the power assembly left suspension 10 and the dislocation connecting block 3 together.
The use process of the bidirectional dislocation connecting bolt part is as follows:
as shown in figure 2, firstly, a lower tightening positioning bolt I1, a lower tightening positioning bolt II 2 and a staggered connecting block 3 are combined into a whole, and the lower tightening positioning bolt I1 and the lower tightening positioning bolt II 2 are fixed on a vehicle body longitudinal beam assembly 8 in a tightening mode.
The upper tightening positioning stud I4, the upper tightening positioning stud II 5 and the dislocation connecting block 3 are tightened and fixed, and then the power assembly right suspension 9 and the upper tightening positioning stud II 5 are screwed and connected through a stud nut II 7, so that the power assembly right suspension 9 and the vehicle body longitudinal beam assembly 8 dislocation hole are effectively connected; the power assembly left suspension 10 is connected with an upper screwing positioning stud I4 and a stud nut I6 in a screwing mode, and therefore the power assembly left suspension 10 is effectively connected with an offset hole of a vehicle body longitudinal beam assembly 8.
