Description
Technical field
The invention belongs to axletree manufacturing technology field used for rail vehicle, and in particular to a kind of axle for vehicle taper detection auxiliary
Utensil and method.
Background technology
With the fast development of track traffic in recent years, the structure of axle for vehicle is also in updating, for the side of press fitting
Just and other cooperation reasons, Some vehicles axle devise tapered configuration, and such as some city railway vehicle axles have 1 at wheel seat：300 tapers
It is required that some EMUs axles for vehicle have 1 at gear block：The requirement of 50 tapers.Due to taper, using common external diameter thousand
Divide chi can not accurately detect a certain sectional dimension, also can not judge whether taper meets drawing requirement.
Typically detected in the prior art for detection axial cone degree using three coordinate measuring machine or socket gauge mode.
When being detected using three coordinate measuring machine to all tapers to, axle for vehicle must be transported to completion detection between detection；In the presence of
The shortcomings that be：1st, a three coordinate measuring machine price is purchased at 2,000,000 yuan or so, is built plus foundation construction and independent room total
Expense is at 2,400,000 yuan or so, and uneconomical, investment cost is higher；2nd, need to transport axle for vehicle to specified location to be detected, very
Inconvenience, meanwhile, because handling transit link increases, axle for vehicle protection is improper, and transportation axle for vehicle is also easy to produce to collide with and wounded；3、
In process, if often walking a procedure, just axle for vehicle is unloaded down to transport to measured between three coordinate measurements, operation is non-
Often trouble, causes production efficiency to substantially reduce.
When carrying out taper detection using socket gauge frame mode, a kind of set consistent with axle for vehicle taper in theory is designed and produced
Rule, socket gauge is enclosed on axle, and observation contact situation determines whether taper is correct；Have the drawback that：1st, due to vehicle shaft diameter
Larger, the socket gauge specification being used cooperatively is big, heavy, and execute-in-place is very laborious inconvenient；2nd, such a socket gauge mode is, it is necessary to by car
Axle is unloaded down, and socket gauge is enclosed on axle, is not suitable for in-process measurement, is otherwise needed to design and produce out sizes specification
Socket gauge, the measurement during could meeting；3rd, situation is contacted with axle for vehicle by eye-observation socket gauge when judging and determines taper,
Accuracy is poor.
