Problems solved by technology

The second is the spin repair of the worn wheel set. The time taken to repair the geometric size and accuracy of the wheel set affects the efficiency of train operation.
The single and fixed non-falling wheel lathes in the prior art have poor precision and low efficiency, and can no longer meet the current increasing maintenance needs. It is very urgent to develop multi-axis non-falling wheel lathes and greatly improve the processing efficiency of non-falling wheels Require

Abstract

The invention discloses a single-shaft and four-shaft combined type numerical control non-pulling wheel lathe which comprises a first foundation. The first foundation is provided with vacancy positions for installing two single-shaft non-pulling wheel lathes, wherein the first lathe is installed on one vacancy position, and a transition track is erected on the other vacancy position. Train wheel sets can enter the first lathe through a first track, a second track and the transition track. The second lathe can be further installed on the other vacancy position to machine a single wheel set, or one more second foundation is increased, and a third lathe and a fourth lathe are installed on a self-adaptive train bogie wheel set shaft distance adjusting device, in a free combination manner, one single-shaft non-pulling wheel lathe is developed into a double-shaft non-pulling wheel lathe or a four-shaft non-pulling wheel lathe and used for repairing and maintaining the undisassembled wheels of various vehicles, the numerical control non-pulling wheel lathe can turn and maintain four wheel sets on two bogies on the same compartment simultaneously at most and can also be switched into two independent non-pulling wheel lathe operation modes, and the requirement for machining various wheel set treads and rims can be met.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a single-axis numerical control non-dropping wheel lathe which is combined into a double-axis numerical control non-dropping wheel lathe and a four-axis numerical control non-dropping wheel lathe. Background technique [0002] With the continuous development of my country's railway construction, especially several major speed increases, the number of trains has continued to increase, the operating density of vehicles has increased, and the quality and efficiency of trains have continued to improve, especially for bullet trains. In order to ensure the running quality and efficiency of trains, higher requirements are put forward for the overhaul quality and overhaul efficiency of train wheelsets. First, the overhaul of the geometric dimensions and accuracy of the wheelset is an important content in the train maintenance. The rotation repair of the worn wheelsets and t...
