For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of bumper cubing location structure, this bumper cubing location structure comprise the locating piece and the keeper with through hole of fixed connection; This through hole comprises that xsect is that circular upper and lower and xsect is square middle part; Said upper part diameter is identical with the diameter of bottom, and the length of side at said middle part is greater than upper part diameter.
Said keeper is connected through screw and/or pin with said locating piece.
Said screw and/or pin are avoided said through hole and are extended.
The bearing of trend of said through hole is identical with the bearing of trend of said screw and/or pin.
Said keeper is formed from steel.
A kind of bumper cubing comprises: bumper; And above-mentioned bumper cubing location structure.
Said bumper is fixedly connected through dog screw with said bumper cubing location structure, and said dog screw runs through the part of the through hole and the locating piece of bumper, keeper.
The diameter of the upper and lower of through hole is identical respectively at the diameter of said dog screw.
Said bumper is fixedly connected through the expansion ejector pin with said bumper cubing location structure, and said expansion ejector pin runs through the part of the through hole of bumper and keeper.
The length of side at the middle part of through hole is greater than the maximum gauge of said expansion ejector pin.
Adopt the bumper cubing location structure of the utility model; Can in two kinds of different fit of the accurate location of bumper cubing and the assembling and positioning of actual entrucking, realize replacing, both can accurately measure, can on the bumper cubing, adjust measurement products again and simulate the assembly structure of entrucking bumper; Thereby find bumper size existing problems apace; Can analyze contrast with client's measurement result, the guide product adjusted size is for the project process exploitation has been practiced thrift the time.

Embodiment
Below in conjunction with accompanying drawing, provide the preferred embodiment of the utility model, and describe in detail, enable to understand better function, the characteristics of the dynamic anti-rotation positioning device of the utility model.
Accurate location according to the bumper cubing location structure of the utility model is as shown in Figure 3, and bumper 2 is fixed on the locating piece 3` through dog screw 1`.
Wherein, said dog screw 1` runs through bumper 2, keeper 6 and locating piece 3` successively.
Wherein, this dog screw 1` and locating piece 3` can be configured according to mode well known in the prior art.
Because the diameter of dog screw 1` is identical with the diameter in bumper 2 holes; Therefore accurately back, location product cannot be adjusted; Utilize the bumper cubing of the utility model to carry out accurate location survey and have only a kind of size, thus the detection demand of the convenient part of producing in batches.
According to the keeper 6 of the bumper cubing location structure of the utility model like Fig. 4 and shown in Figure 5.
As can be seen from Figure 4, said keeper 6 is one-body molded.In a preferred embodiment of the utility model, the outer shape of this keeper 6 is depicted as square column type.Should be appreciated that any other suitable shape all can be used in the utility model, and is for example cylindrical.
The center of keeper 6 is provided with through hole 61; Around this through hole 61; Be provided with some screws and/or the pin keeper 6 is fixedly connected with locating piece 3` (see figure 3), wherein, the bearing of trend of this through hole 61 is identical with the bearing of trend of said screw and/or pin.When the outside of keeper 6 was rendered as square column type, this screw and/or pin were depicted as and are arranged near four seamed edges, represent with 62 and 63 in the drawings.
As can be seen from Figure 5, the diameter of through hole 61 on its bearing of trend of said keeper 6 changes.In a preferred embodiment, along the bearing of trend of said through hole 61, can this through hole 61 be divided into top 610, middle part 620 and bottom 630.Wherein, the xsect of said top 610 and bottom 630 is depicted as circle; And that the xsect at middle part 620 is depicted as is square.The diameter on top 610 is identical with the diameter of bottom 630, and the length of side at middle part 620 is greater than the diameter of 610/ bottom 630, top.And the distance that any two screws that are provided with round through hole 61 and/or the footpath between the pin make progress is all greater than the length of side at middle part 620, i.e. screw and/or pin and 62,62 avoid this through hole 61 and extend.
Utilize the bumper cubing location structure of the utility model; Except the purpose that realizes above-mentioned accurate location survey product size; Can also simulate actual entrucking state and measure, its simulation entrucking assembling is as shown in Figure 6, through expansion ejector pin 4` bumper 2 is fixed on this keeper 6.
The length of side at the middle part 620 of this keeper 6 is greater than the maximum gauge of expansion ejector pin 4`, thereby realizes ccontaining and the purpose of dodging expansion ejector pin 4`.
Wherein, the diameter with the vehicle body stamping holes is identical respectively for the diameter of the top 610 of the through hole 61 of this keeper 6 and bottom 630.Promptly simulate the vehicle body panel beating through the top of locating piece 6; Because the diameter in bumper hole 2 is identical with the diameter of dog screw 1; And the diameter of expansion ejector pin 4` is littler than the diameter of dog screw 1, and therefore, expansion ejector pin 4` can adjust in the bumper hole; Can in simulation entrucking assembling, adjust the integral position of bumper, thus measurement size.Because the actual entrucking locator meams the when locator meams of this simulation entrucking assembling is measured with the customers' place bumper is identical; Can adjust the integral position of bumper where necessary; Therefore can check bumper whether can cooperate the state of vehicle body well, thereby solve in the prior art because two kinds of inconsistent problems of the locator meams measurement result that causes inequality.
In a preferred embodiment of the utility model, it is identical with common locating piece 3` that the material of said keeper 6 is preferably, steel for example, and other any optional materials also can be used among the embodiment of the utility model.
The size of said keeper 6 can be adjusted according to the actual needs of bumper product.
Obviously, according to the above, the many corrections and the modification of the utility model are possible.Therefore, should be appreciated that within the scope of the appended claims that the utility model can be implemented through being different from above-mentioned specifically described other modes.
