Description
Technical field
The utility model relates to a kind of fixed structure, and particularly a kind of fixed structure for auto rectifier bridge bracket and pole plate, belongs to automobile rectifier bridge technical field.
Background technology
Existing automobile rectifier bridge supporting structure as shown in Figure 1, rack body 1 is provided with some installation through holes 11 for being fixed on by pole plate on support.During installation, positive plate 2 and negative plate 3 are installed together, then pole plate entirety is placed on the relevant position of rack body 1, then use rivet successively through negative plate 3, positive plate 2 and rack body 1, finally by flanger to the process of rivet flange, pole plate and support is made to form robust structure.
Using middle discovery, because support itself adopts plastic construction, therefore when using rivet through when installing through hole 11, if firmly not, then can not, by rivet through installing through hole, pole plate and support cannot be made to form robust structure; If firmly excessive, support can be caused to ftracture because surface stress is excessive.Therefore, existing riveted joint operating efficiency is lower, and situation production cost being increased because support breaks can occur simultaneously.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of fixed structure for auto rectifier bridge bracket and pole plate, high efficiencyly can realize pole plate and support forms robust structure, the situation simultaneously effectively avoiding support to ftracture, cost-saving.
To achieve these goals, a kind of fixed structure for auto rectifier bridge bracket and pole plate that the utility model adopts, the pole plate comprising rack body and can be injection-moulded on rack body, described rack body is provided with some installation through holes for being fixed on by pole plate on support;
Described pole plate comprises positive plate and negative plate, positive and negative pole plate is respectively equipped with the installing hole coordinated with described installation through hole;
Also comprise being arranged on and install in through hole for positive and negative pole plate being fixed on the annular knurl rivet on rack body;
Be provided with aluminium pad in described installation through hole, positive and negative pole plate is fixed on described rack body by described annular knurl rivet, and annular knurl rivet adopts interference fit with the installation through hole being provided with aluminium pad.
As improvement, the aluminium pad installed in through hole is injection-moulded on rack body.
As improvement, the front end of described annular knurl rivet is provided with some straight burrs that can coordinate with aluminium pad in installation through hole.
As improvement, the length of described straight burr is mated with aluminium pad length.
As improvement, described straight burr equidistantly, be set in parallel in the front end of rivet, the direction of straight burr is consistent with the axis direction of rivet.
Compared with prior art, the beneficial effects of the utility model are: by injection moulding aluminium pad in the installation through hole of rack body, effectively can absorb the stress of rack surface, when rivet press-in is installed in through hole, absorbing stress by aluminium pad effectively prevents support from splitting, and avoids that stress in traditional approach is excessive and support that is that occur ftractures the situation causing production cost to increase; Adopt rivet annular knurl pressing structure, coordinated with aluminium pad by the annular knurl of rivet front end, make fast, in rivet press-in rack body, to save the riveted joint time, improve production efficiency, in addition also can recycling rivet, cost-saving.
Accompanying drawing explanation
Fig. 1 is existing supporting structure schematic diagram;
Fig. 2 is mounting structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of the annular knurl rivet that the utility model uses;
In figure: 1, rack body, 11, through hole is installed, 2, positive plate, 3, negative plate, 4, annular knurl rivet, 41, straight burr.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figures 2 and 3, a kind of fixed structure for auto rectifier bridge bracket and pole plate, the pole plate comprising rack body 1 and can be injection-moulded on rack body 1, described rack body 1 is provided with some installation through holes 11 for being fixed on by pole plate on support;
Described pole plate comprises positive plate 2 and negative plate 3, positive plate 2, negative plate 3 is respectively equipped with and the installing hole installed through hole 11 and coordinate;
Also comprise being arranged on and install in through hole 11 for positive and negative pole plate being fixed on the annular knurl rivet 4 on rack body 1;
Be provided with aluminium pad in described installation through hole 11, positive plate 2, negative plate 3 are fixed on described rack body 1 by described annular knurl rivet 4, and annular knurl rivet 4 adopts interference fit with the installation through hole 11 being provided with aluminium pad.
As the improvement of embodiment, the aluminium pad installed in through hole 11 is injection-moulded on rack body 1, and processing is simple, and overall structure integrated degree is high, ensure that whole structural stability, easy to use.
As the improvement of embodiment, the front end of described annular knurl rivet 4 is provided with some straight burrs 41 that can coordinate with aluminium pad in installation through hole 11, adopts straight burr 41 to coordinate with aluminium pad and realizes interference fit, ensure that pole plate and support form robust structure.
