Abstract

一种不锈钢车顶骨架专用调修拉杆，其特征在于：钩型夹体与螺旋拉杆转动连接，螺旋拉杆与双向螺母框连接，钩型夹体上固定有螺母，与螺母配合有丝杠，丝杠的另一端为压头。本实用新型的积极效果在于：钩型夹体深入不锈钢车顶骨架边梁凹槽内，通过丝杠和压头对不锈钢车顶骨架边梁进行夹紧。通过旋拧双向螺母框，使螺旋拉杆向里拉或者向外撑，实现对边梁扭曲和内缩外涨变形现象进行控制和调修，外部表面无夹压痕迹。

Description

不锈钢车顶骨架专用调修拉杆
技术领域
本实用新型属于轨道客车制造技术领域，涉及不锈钢车顶骨架在组成焊接过程中边梁变形控制和调修。 
背景技术
轨道客车不锈钢车顶骨架在组成焊接中产生变形，其边梁产生扭曲和内缩外涨现象，普通拉杆调修会使车顶外部表面有夹压痕迹，无法达到从内部夹压实现变形控制和调修作用。 
发明内容
本实用新型的目的是提供一种不锈钢车顶骨架专用调修拉杆，解决不锈钢车顶骨架在组成焊接中边梁变形问题，达到从内部夹压变形控制和调修车顶，实现外部表面无夹压痕迹。 
为实现上述目的，本实用新型提供一种不锈钢车顶骨架专用调修拉杆，其特征在于：钩型夹体与螺旋拉杆转动连接，螺旋拉杆与双向螺母框连接，钩型夹体上固定有螺母，与螺母配合有丝杠，丝杠的另一端为压头。 
本实用新型的积极效果在于：钩型夹体深入不锈钢车顶骨架边梁凹槽内，通过丝杠和压头对不锈钢车顶骨架边梁进行夹紧。通过旋拧双向螺母框，使螺旋拉杆向里拉或者向外撑，实现对边梁扭曲和内缩外涨变形现象进行控制和调修，外部表面无夹压痕迹。 
附图说明
图1为本实用新型结构示意图； 
图2是图1中A的放大图。
具体实施方式
参照图1、2，不锈钢车顶骨架边梁1已经与弧形车顶2组合焊接为一体，钩型夹体3深入不锈钢车顶骨架边梁1的凹槽内。钩型夹体3用转轴7与螺旋拉杆8连接，螺旋拉杆8与双向螺母框9连接。钩型夹体3上固定有螺母4，通过旋拧丝杠5使压头6将不锈钢车顶骨架边梁1夹紧。 
当顺时针或逆时针旋拧双向螺母框9时，螺旋拉杆8带动钩型夹体3及压头6夹紧不锈钢车顶骨架边梁1，使之向里拉或者向外撑，实现对边梁扭曲和内缩外涨变形现象进行控制和调修，外部表面无夹压痕迹。
