Description

铁路客车轮对动平衡后的去重修正工艺 技术领域
本发明涉及轮对动平衡后的去重修正工艺。
背景技术
目前， 中国铁道客车轮对动平衡检测之后， 采用落后的添重法进 行修正，此法是在轮对较轻的一面，用一定重量的金属条贴在该位置， 然后用螺栓紧固。 车辆运行的事实表明， 此方法很不可靠， 修正用的 金属条在运行一段时间后基本丢失， 这样， 使车辆运行平稳性、 舒适 性受到了影响。
发明内容
本发明所要解决的技术问题是提供一种去重修正工艺，适用于目 前所有轨距的轨道客车轮对， 方法可靠， 使用成本低， 效率高。
为解决上述技术问题，本发明提供一种铁路客车轮对动平衡后的 去重修正工艺， 其特征在于包括下列歩骤：
( 1 ) 根据车轴轴端的螺纹孔结构， 设计主轴端夹具和尾座端夹 具；
( 2 ) 将主轴端夹具与车轴固定；
( 3 ) 将轮对吊起， 主轴端夹具中心孔对准车床主轴端的顶尖， 夹具的柄部插入拨盘孔；
( 4 ) 将尾座端夹具的偏心端目测对准动平衡的去重端刻线， 然 后套在车轴上， 将车床尾座顶尖对准该夹具的中心孔并顶紧；
( 5 ) 将刀具对准去重部位， 启动车床， 根据需要修正的重量完 成去重工作；
( 6 ) 启动按钮， 停止车床转动， 由天车吊住轮对后， 松开车床 尾座， 逐一卸下主轴端夹具和尾座端夹具。
本发明适用性强， 适用于目前所有轨距的轨道客车轮对； 使用成 本低，对比动平衡数控去重专机， 其刀具成本仅为它的 10%; 效率高， 适合工序分散性工艺。
附图说明
图 1是主轴端夹具结构示意图；
图 2是沿图 1中 A— A线的剖视图；
图 3是尾座端夹具结构示意图；
图 4是图 3的剖视图。
具体实施方式
参照图 1、 图 2， 主轴端夹具包括头部 1和柄部 4， 头部和柄部 悍接组成， 头部中心开有中心孔 3， 上表面加工有圆形凹槽并开有三 个固定孔 2。
参照图 3、 图 4，尾座端夹具是在圆形金属板 6—面加工有凹槽， 另一面加工有凸台 5， 凹槽内是硫化橡胶层 7， 夹具上加工有偏心孔 8。
去重修正工艺如下：
( 1 ) 根据车轴轴端的螺纹孔结构， 设计主轴端夹具和尾座端夹 具；
( 2 ) 将主轴端夹具用对应轴端螺纹孔的三个内六角螺栓通过固 定孔与车轴紧固；
(3) 用天车将轮对吊起， 主轴端夹具中心孔对准车床主轴端的 顶尖， 夹具的柄部插入拨盘孔；
(4) 将尾座端夹具的偏心孔目测对准动平衡的去重端刻线， 然 后通过凹槽套在车轴上， 将车床尾座顶尖对准该夹具的中心孔并顶
(5) 将刀具对准去重部位， 启动车床， 转速 10-15转 /分， 将刀 具对准去重部位， 以每转 0.15 毫米的进给量， 手动进给， 根据需要 修正的重量， 判断钢屑切下的重量， 直至完成去重工作（在工作完成 5 条左右轮对之后， 基本会作出正确判断）； 车削修正的范围不大于 120° ， 深度不大于 4毫米， 粗糙度 Ral2.5-6.3范围内； 根据需要修 正的重量完成去重工作；
(6) 启动按钮， 停止车床转动， 由天车吊住轮对后， 松开车床 尾座， 逐一卸下主轴端夹具和尾座端夹具。
