Abstract
The utility model discloses a connecting and positioning structure of an automobile aluminum alloy framework, which includes a connecting piece, an aluminum alloy pipe fitting, a lock bolt and a lock nut, wherein the connecting piece is provided with at least two tubular connectors; radial through holes are arranged on the outer walls of the tubular connectors and the aluminum alloy pipe fitting; the aluminum alloy pipe fitting is inserted in the tubular connectors; the lock bolt penetrates the through holes of the tubular connectors and the aluminum alloy pipe fitting; and the end of the lock bolt penetrating out of the through holes is in threaded connection with the lock nut. By adopting the connecting method, the possibility for the aluminum alloy pipe fitting to deform is little, the connecting piece can adopt the small die and fine production, and has low cost and satisfactorily ensured precision and allowance, the assembling precision for connecting the automobile framework is effectively improved, the deviation on the whole automobile assembling size is reduced, the whole automobile assembling precision is ensured, the production quality of the product is improved, and the remarkable quality improvement of the terminal product is achieved with extremely small cost.
Description
Technical field
The utility model relates to the aluminum alloy framework of automobile, particularly a kind of connection position structure of aluminium alloy car skeleton.
Background technique
For light-weight electric automobile and miniature electric automobile, in order to alleviate the weight of car body, its vehicle body adopts aluminum alloy framework more.The aluminum alloy framework of present most main engine factory all is to be welded by the aluminum alloy pipe fitting; But because the aluminum alloy pipe fitting very easily causes distortion in welding process; Therefore the welding precision of aluminum alloy pipe fitting is lower, this welding manner and be not suitable for the requirement of automatic production.Have, welding dense smoke that easily can be a large amount of when adopting welding manner welding aluminum alloy pipe fitting can pollute the site environment of manufacturing shop, and then can cause adverse effect to the ordinary production in workshop again.
The model utility content
To the deficiency of above-mentioned existing technology, the technical problem that the utility model will solve provides a kind of aluminium alloy car skeleton connection position structure simple and reliable, that assembly precision is high of implementing.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of aluminium alloy car skeleton connects position structure; It comprises link, aluminum alloy pipe fitting, lock bolt and locking nut; Said link has at least two tubulose connecting heads; The outer wall of said tubulose connecting head, aluminum alloy pipe fitting is provided with penetration hole radially; Said aluminum alloy pipe fitting is inserted in the said tubulose connecting head, and said lock bolt passes the penetration hole of said tubulose connecting head, aluminum alloy pipe fitting, and an end that passes penetration hole of said lock bolt is threaded with said locking nut.
Preferably, the inwall of said tubulose connecting head is provided with limited step.
Preferably, the shape of said tubulose connecting head can be " one " font, L type, U type or X type.
Technique scheme has following beneficial effect: this aluminium alloy car skeleton connects position structure and adopts bolted mode that the aluminum alloy pipe fitting is connected into aluminum alloy framework through link, adopts this Placement aluminum alloy pipe fitting to be difficult for producing distortion, and link can adopt little mould; Production becomes more meticulous; Expense is not high, but can its precision of excellent guarantee and tolerance, so just can effectively improve connect the assembly precision of body frame; Reduce the deviation on the car load fitted position; And then guarantee the precision that car load assembles, and improved the production quality of product, brought the tangible quality-improving of end product with minimum cost.Adopt this connection position structure can be convenient to realize automatic production simultaneously, can effectively promote the beat and the efficient of production.
Above-mentioned explanation only is the general introduction of the utility model technological scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the utility model embodiment's a decomposition texture schematic representation.
Embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1; This aluminium alloy car skeleton connects link 1, aluminum alloy pipe fitting 2, lock bolt 3 and the locking nut 4 that position structure comprises a L type; The two ends of link 1 are respectively equipped with a tubulose connecting head 11; The outer wall of tubulose connecting head 11 is provided with penetration hole 12 radially, a limited step 13 on the inwall of tubulose connecting head 11.Also be provided with penetration hole 21 radially on the outer wall of aluminum alloy pipe fitting 2, aluminum alloy pipe fitting 2 is inserted in the tubulose connecting head 11, and the end of aluminum alloy pipe fitting 2 withstands on the limited step 13, and penetration hole 21 is on the same straight line with the center of penetration hole 12.Lock bolt 3 passes the penetration hole 12 of tubulose connecting head 11 and the penetration hole 21 of aluminum alloy pipe fitting respectively; An end that passes tubulose connecting head 11 penetration holes of lock bolt 3 is threaded with locking nut 4, and locking locking nut 4 can connect into an overall structure with link 1 and aluminum alloy pipe fitting 2.
Another tubulose connecting head 11 of link 1 is connected with other aluminum alloy pipe fittings, or the other end of aluminum alloy pipe fitting 2 is connected with other links, link 1 can also adopt shapes such as " one " font, U type or X type.Combination with one another connection through aluminum alloy pipe fitting, link can form the aluminium alloy car skeleton like this.
This aluminium alloy car skeleton connects position structure and adopts bolted mode that the aluminum alloy pipe fitting is connected into aluminum alloy framework through link, adopts this Placement aluminum alloy pipe fitting to be difficult for producing distortion, and link can adopt little mould; Production becomes more meticulous; Expense is not high, but can its precision of excellent guarantee and tolerance, so just can effectively improve connect the assembly precision of body frame; Reduce the deviation on the car load fitted position; And then guarantee the precision that car load assembles, and improved the production quality of product, brought the tangible quality-improving of end product with minimum cost.Adopt this connection position structure can be convenient to realize automatic production simultaneously, can effectively promote the beat and the efficient of production.
More than aluminium alloy car skeleton that the utility model embodiment is provided connect position structure and carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; On embodiment and application area, all can change to some extent; Therefore this description only is used for should not be construed as the restriction to the utility model in the utility model embodiment is described, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
