Utility model content
The utility model is directed to deficiencies of the prior art, provides a kind of reasonable for structure, wheel hub being connected firmly
Air-leakage test supporting rack.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of wheel hub air-leakage test supporting rack, including wheel hub test machine for detecting gas tightness, fixed seat, fixed frame, wheel hub,
Hexagon socket head cap screw, wheel hub test machine for detecting gas tightness bottom have bottom plate, have fixed seat in the middle part of bottom plate, inside fixed seat
It is uniformly distributed positioning convex platform slot, inside positioning convex platform slot there is tooth socket, the fixed frame bottom to be uniformly distributed positioning convex platform, position
There is external tooth, positioning convex platform to be inserted into positioning convex platform slot, external tooth and tooth socket fit, fixed seat middle part have taper convex outside boss
There is cone boss slot, cone boss to be inserted into cone boss slot for platform, fixed frame inside, and fixed seat inner homogeneous is distributed internal thread
Slot, fixed frame inner homogeneous are distributed stepped hole, and hexagon socket head cap screw is inserted into stepped hole and internal thread groove, have at the top of fixed seat and hold
Top surface is connect, fixed frame bottom has pressing bottom surface, accepts top surface and pressing bottom surface, and fixed seat is connect with fixed frame.
The symmetrical riser in wheel hub test machine for detecting gas tightness both sides, riser bottom are welded with bottom plate, at the top of bottom plate
There is pressing plate, pressing plate to be slided on guide rail column for symmetrical guide rail column, wheel hub test machine for detecting gas tightness middle part, the fixed frame
The symmetrical support post in top, support post inside have hanging groove, there is hanging rod, hanging rod are inserted into the middle part of wheel hub in hanging groove.
Advantageous effect：
Positioning convex platform is inserted into positioning convex platform slot, and external tooth and tooth socket fit, contact surface are arcwall face, extend contact surface
Length makes carrying be more uniformly distributed, and external contact face is flute profile, can uniformly carry rotation load, make to be connected firmly, cone boss
It is inserted into cone boss slot, while playing positioning action, contact surface is taper surface, can uniformly carry gravitational load and survey
Pressure when examination, it is reasonable for structure, it is connected firmly, symmetrical support post, fixed frame can be replaced at the top of fixed frame, inside
Hanging groove can be sizes, coordinate from a variety of different wheel hubs, be convenient for changing, it is reasonable for structure.
