Abstract

本实用新型涉及一种挖掘机的涨紧装置，包括弹簧座板、螺母、拉杆，其特征在于，所述的弹簧座板与拉杆的螺母接触面设为球面。本实用新型与现有技术相比，具有结构简单可靠，能自动消除拉杆上斜应力。

Description

挖掘机的涨紧装置
技术领域
本实用新型属于挖掘机配件，尤其是一种挖掘机的涨紧装置。 
背景技术
目前，国内外通用挖掘机的涨紧装置的涨紧螺母都是平面接触，由于工作上的原因造成螺母与弹簧座为斜面接触，拉杆会产生斜应力，斜应力会让拉杆容易疲劳导致断裂，造成整条涨紧装置报废。 
发明内容
本实用新型的目的在于提供一种结构简单、耐用、安全可靠的挖掘机的涨紧装置。 
本实用新型的技术解决方案是这样的，一种挖掘机的涨紧装置，包括弹簧座板、螺母、拉杆，其特征在于，所述的弹簧座板与拉杆的螺母接触面设为球面。 
本实用新型与现有技术相比，具有结构简单可靠，能自动消除拉杆上斜应力。 
附图说明
附图1为本发明的整体结构主视剖视图。
附图1中，弹簧座板（1）、螺母（2）、拉杆（3）、球面（4）。 
具体实施方式 
    本实用新型的最佳实施例是这样的，参照附图1所示，一种挖掘机的涨紧装置，包括弹簧座板、螺母、拉杆，其中，所述的弹簧座板1与拉杆3的螺母2接触面设为球面4。拉杆3工作时不会产生斜应力。
