Abstract
The invention relates to automobile wheels, in particular to an aluminum alloy wheel type test bolt. The aluminum alloy wheel type test bolt is characterized in that a bolt sleeve is disposed on a bolt stem, the bolt sleeve is provided with bolt holes, which are not smaller than the bolt diameter, along a spherical axis, cut in a way perpendicular to the bolt holes and not larger than a hemisphere, the bolt sleeve is sleeved on the bolt stem through the bolt holes, and the sleeve cutting face is contacted with a nut. The integral bolt for connecting an aluminum alloy wheel with a bench testing machine is divided into two parts, one part is the fixing bolt, the other part is the bolt sleeve with various spherical faces, the fixing bolt can be matched with bolt sleeve with the corresponding spherical face according to PCD (pitch circle diameter) specifications of different products, the rear end face of the bolt sleeve is closely matched with the nut, the front end face of the bolt sleeve is closely matched with bolt holes on the bench testing machine, and accordingly bearing capacity of the aluminum alloy wheel, wheel rotation time, instant impact borne by part of the aluminum alloy wheel and the like can be tested. The aluminum alloy wheel type test bolt is convenient to operate, high in work efficiency, accurate in test and the like.
Description
Technical field
The present invention relates to the wheel of automobile, the bolt that a kind of aluminum-alloy wheel type approval test easy to operate, highly versatile is specifically used.
Background technique
As everyone knows, aluminum-alloy wheel will pass through cast blank, heat treatment process, numerical control machine tool turning processing, produce finished product after the technologies such as surface spraying preservative treatment, also need carry out stand test checking before aluminum-alloy wheel dispatches from the factory just can dispatch from the factory to be installed on the automobile and use, stand test is by the usability test behind the bolt simulation aluminum-alloy wheel connection car load, aluminum-alloy wheel is applied stressed by testing machine, wheel rotates certain number of times, or aluminum-alloy wheel local moment born impact force, press aluminum-alloy wheel stand test standard, differentiate aluminum-alloy wheel and whether satisfy the vehicle performance requirement, at present, it all is to adopt conventional bolt that conventional aluminum-alloy wheel stand test machine connects, conventional bolt is provided with screw rod and nut is formed, screw rod and nut joint are 90 ° of angles, have in order to increase bearing area, between screw rod and nut, set up platen, because the designed bolt hole of each main engine factory or different automobile types is different, what particularly the fitting surface of bolt hole had is tapered, what have is spherical in shape, when testing, the stand test machine also to have inconvenient operation according to using the bolt of selecting different open types, inefficiency, testing precision is influenced.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, propose a kind of easy to operate, high working efficiency, aluminum-alloy wheel type approval test bolt that versatility is good.
The present invention can reach by following measure.
A kind of aluminum-alloy wheel type approval test bolt, comprise the bolt of being formed by screw rod and nut, screw rod and nut joint are 90 ° of angles, it is characterized in that screw rod is provided with bolt collar, bolt collar is to be provided with the screw hole that is not less than screw diameter along the spheroid axis, and the body that is not more than hemisphere of vertical screw hole cutting, bolt collar is enclosed within on the screw rod through screw hole, and the body cutting surface contacts with nut.
Screw rod of the present invention is connected with nut through platen, and bolt collar is enclosed within on the screw rod through screw hole, and the body cutting surface contacts with platen.
The present invention is separated into two-part with the bolt that aluminum-alloy wheel is connected with the stand test machine by the integrated type bolt, a part is fixing bolt, a part designs multiple sphere bolt collar in addition, root different product PCD specification, can use fixing bolt to cooperate corresponding sphere bolt collar, the carrying that closely cooperates of the ear end face of bolt collar (cutting surface) and nut, bolt hole on the front-end face of bolt collar and the stand test machine closely cooperates, hold the ability of adding with the test aluminum-alloy wheel, the wheel number of revolutions, aluminum-alloy wheel local moment is born impact force etc., has easy to operate, high working efficiency, test advantages such as accurate.

Fig. 2 is a kind of structural representation of bolt collar among the present invention.
Fig. 3 is a kind of application state schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in the figure, a kind of aluminum-alloy wheel type approval test bolt, comprise the bolt of being formed by screw rod 1 and nut 2, screw rod 1 is 90 ° of angles with nut 2 joints, have in order to increase bearing area, between screw rod and nut, set up platen, the structure of above-mentioned each constituent element and the interconnected relationship between them are same as the prior art, this does not give unnecessary details, the invention is characterized in that screw rod 1 is provided with bolt collar 3, bolt collar 3 is to be provided with the screw hole that is not less than screw diameter along the spheroid axis, and the body that is not more than hemisphere of vertical screw hole cutting, bolt collar 3 is enclosed within on the screw rod 1 through screw hole, the body cutting surface contacts with nut 2, described screw rod 1 is connected with nut 2 through platen 4, bolt collar 3 is enclosed within on the screw rod 1 through screw hole, the body cutting surface closely contacts with platen 4, the present invention is separated into two-part with the bolt that aluminum-alloy wheel is connected with the stand test machine by the integrated type bolt, a part is fixing bolt, a part designs multiple sphere bolt collar in addition, root different product PCD specification, can use fixing bolt to cooperate corresponding sphere bolt collar, the carrying that closely cooperates of the ear end face of bolt collar (cutting surface) and nut, bolt hole on the front-end face of bolt collar and the stand test machine closely cooperates, hold the ability of adding with the test aluminum-alloy wheel, the wheel number of revolutions, aluminum-alloy wheel local moment is born impact force etc., has easy to operate, high working efficiency, test advantages such as accurate.
Claims (2)
