Embodiment Construction
[0039] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0040] See attached figure 1 - attached Figure 4 , the vehicle axle taper detection auxiliary device of the present invention comprises:
[0041] Taper sample block 1, the taper of the sample block upper end surface 101 and the sample block lower end surface 102 of the taper sample block 1 is the same as the taper of the vehicle axle 3 to be detected;
[0042] And the sample block fixing structure, by the sample block fixing structure, the taper sample block 1 is fixed on the vehicle axle 3 to be detected, so that the center line of the taper sample block 1 is parallel to the vehicle axle 3 axes to be detected, and the taper sample The end face of the block 1 is perpendicular to the axis of the vehicle axle 3 to be detected.
[0043] The sample block fixing structure is a sample block mounting bracket 2, and the sample block mounting bracket 2 includ...

An auxiliary device for vehicle axial taper detection and a method for vehicle axle taper detection belong to the vehicle axle manufacturing technology field for a rail vehicle, the objective of the invention is to provide an auxiliary device for vehicle axle taper detection, and the problems are solved that a three-coordinate measuring machine is high in cost, easy to generate collision and low in production efficiency in the prior art and a socket gauge mode is laborious and inconvenient to operate, is not suitable for processing process, low in measurement production efficiency and bad in accuracy; and the vehicle axle can be conveniently measured in the processing process and in the condition that the axle is hanged on an axle rack. The auxiliary device for vehicle axle taper detection comprises: a taper sample piece, wherein the tapers of the upper end face and the lower end face of the sample piece of the tamper sample piece are the same as the tapers of the portion to be detected of the vehicle axle; and a sample piece fixing structure, wherein the sample piece fixing structure is configured to fix the taper sample block at the portion to be detected of the vehicle axle to allow the center line of the taper sample piece to be parallel with the axis of the vehicle axle to be detected and allow the end face of the taper sample piece to be perpendicular to the axis of the vehicle axle to be detected.
Description
technical field [0001] The invention belongs to the technical field of axle manufacturing for rail vehicles, and in particular relates to an auxiliary device and method for detecting the taper of a vehicle axle. Background technique [0002] With the rapid development of rail transportation in recent years, the structure of the vehicle axle is also being continuously improved. For the convenience of press-fitting and other matching reasons, some vehicle axles are designed with a tapered structure. For example, some urban railway vehicle axles are at the wheel seat. There is a 1:300 taper requirement, and some EMU vehicle axles have a 1:50 taper requirement at the gearbox seat. Due to the taper, it is impossible to accurately detect a certain cross-sectional size by using an ordinary outer diameter micrometer, and it is also impossible to judge whether the taper meets the requirements of the drawing. [0003] In the prior art, a three-coordinate measuring machine or a sleeve...
