Abstract
The utility model provides a follower-cover wheel hub. The follower-cover wheel hub comprises a wheel hub and follower covers and is characterized in that an annular platform and a threaded hole are arranged in a bowl mouth of the center of the wheel hub, concave faces of the follower covers are in contact with the annular platform, the follower covers are fastened by screws, the shapes of the follower covers are formed through extending the shapes of wheel ribs towards the center, the surfaces of the wheel ribs are bright faces which are coated firstly and then are subjected to fine-turning, the surfaces of the follower covers are bright faces which are coated firstly and then are subjected to convex-face fine-turning, meanwhile, the wheel ribs and the annular platform are subjected to fine-turning, and the height from the fine-turned bright faces of the wheel ribs to the annular platform is equal to that from the fine-turned bright faces of the follower covers to the concave faces of the follower covers. The condition that convex faces of the follower covers are level with wheel rib faces of the wheel hub is ensured.
Description
Technical field
The utility model relates to aluminium alloy wheel hub and manufactures field, more specifically, relates to a kind of conformal lid wheel hub.
Background technology
Automotive hub conformal lid because of with the natural transition of wheel hub spoke moulding, moulding is abundant novel, surface working mode is various, the welcome in the developed country markets such as the Shen Shou U.S., current conformal lid wheel hub is assembling conformal lid, the rim of a bowl edge is cast as to cover concavo-convex moulding consistent with conformal, highly fixing installation curved surface, conformal lid concave surface and convex surface can be closely cooperated with wheel hub the rim of a bowl, but can encounter variety of issue in actual production, for example, when the casting demoulding, there is drawing-die in part wheel hub blank, make the whole spoke of drawing-die blank towards interior or outwards skew, while causing machinework, the turning amount of spoke is inconsistent, cause the installation curved surface height of spoke face and the rim of a bowl to be not equal to the height that conformal is high, occur that conformal is stamped height and has low phenomenon, or check and find that there is flaw after bright of finish turning, need bright of the new finish turning of laying equal stress on of application again, now, because having carried out bright of finish turning, the installation curved surface height of spoke face and the rim of a bowl has just in time equaled the height of conformal lid, then finish turning once, spoke face will inevitably be lower than the high height of conformal, owing to being bright wheel hub of finish turning, as long as conformal lid and spoke have not concordant just very obvious, have a strong impact on presentation quality and have to scrap.
Summary of the invention
For above-mentioned technical matters, for stopping conformal lid wheel hub and uneven problem of coordinating of conformal lid, the utility model provides a kind of conformal lid wheel hub, specifically by the following technical solutions: a kind of conformal lid wheel hub, comprise wheel hub and conformal lid, it is characterized in that, in the rim of a bowl at described wheel hub center, be provided with a ring-like platform and a tapped bore, conformal lid concave surface contacts with ring-shaped platform, described conformal lid adopts screw fastening, the moulding of described conformal lid is that spoke moulding is to the continuity at center, described spoke surface is bright of finish turning after first application, the surface of described conformal lid is bright of convex surface finish turning after first application, while finish turning spoke and ring-shaped platform, the height of bright of described spoke finish turning to ring-shaped platform equals bright height to conformal lid concave surface of finish turning of conformal lid.
Uneven for making conformal lid wheel hub not occur that conformal lid coordinates with wheel hub spoke, we adopt following technological means to control:
Between described ring-like platform and described spoke, be provided with relief groove, after the first Fast Coarse Vehicle Processing of described spoke and described ring-shaped platform, stay (1 ~ 1.5) mm allowance, described wheel hub completes and carries out bright spoke operation of finish turning at coating process.
Adopt technique scheme, its advantage has, and does not change the project organization of conformal lid, mould change changes little, does not affect founding property, simple modification machinework turning process and numerical control program, improve the fault-tolerance of blank drawing-die, solved after the bright face of finish turning is done over again the problem without allowance.
Accompanying drawing explanation
Fig. 1 is wheel hub structure schematic diagram of the present utility model;
Fig. 2 is the unitized construction schematic diagram of wheel hub of the present utility model and conformal lid;
A-A sectional structure schematic diagram in Fig. 3 Fig. 2;
B portion enlarged diagram in Fig. 4 Fig. 3.
The specific embodiment
In order more clearly to understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment of present patent application can combine mutually.
As Figure 1-Figure 4: a kind of conformal lid wheel hub, comprise wheel hub 1 and conformal lid 2, in the rim of a bowl 3 at described wheel hub center, be provided with a ring-like platform 4 and a tapped bore 5, described conformal lid concave surface 6 contacts with described ring-shaped platform 4, described conformal lid 2 adopts screw fastening, the moulding of described conformal lid 2 is that described spoke 7 moulding are to the continuity at center, described spoke 7 surfaces are bright of finish turning after first application, the surface of described conformal lid 2 is bright of convex surface finish turning after first application, spoke 7 and described ring-shaped platform 4 described in while finish turning, the height of bright of described spoke 7 finish turnings to described ring-shaped platform 4 equals bright height to conformal lid concave surface 6 of finish turning of described conformal lid 2.
Between described ring-like platform 4 and described spoke 7, be provided with relief groove, after the first Fast Coarse Vehicle Processing of described spoke 7 and described ring-shaped platform 4, stay (1 ~ 1.5) mm allowance, described wheel hub 1 completes and carries out bright spoke 7 operations of finish turning at coating process.
Above-described embodiment is to specific descriptions of the present utility model; only for the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, within the technician of this area makes some nonessential improvement according to the content of above-mentioned utility model to the utility model and adjusts and all to fall into protection domain of the present utility model.
