Hydraulic pump bumping post structure of excavator
The invention provides a hydraulic pump bumping post structure of an excavator. The hydraulic pump bumping post structure comprises a screw bumping post integrated component and a servo plunger baffle; the screw bumping post integrated component comprises a head portion and a body portion connected with the head portion; an annular sealing piece installation groove is formed in the head portion of the screw bumping post integrated component; a sealing piece is arranged in the sealing piece installation groove; an external thread is arranged on the body portion of the screw bumping post integrated component; a bumping post installation groove is formed in the servo plunger baffle; a through hole is formed in the groove bottom of the bumping post installation groove; the head portion of the screw bumping post integrated component is arranged in the bumping post installation groove; the body portion of the screw bumping post integrated component penetrates the through hole; and the body portion of the screw bumping post integrated component is in threaded connection with the through hole. The hydraulic pump bumping post structure has the beneficial effects that abrasion of the sealing piece on a bumping post can be well avoided, and oil leakage of products is prevented.
本发明提供了一种挖掘机液压泵挡柱结构，包括螺钉挡柱一体构件和伺服柱塞挡板，所述螺钉挡柱一体构件包括头部和与所述头部连接的身部，所述螺钉挡柱一体构件的头部上设有环形的密封件安装凹槽，所述密封件安装凹槽内设有密封件，所述螺钉挡柱一体构件的身部设有外螺纹，所述伺服柱塞挡板上设有挡柱安装凹槽，所述挡柱安装凹槽的槽底设有通孔，所述螺钉挡柱一体构件的头部设置在所述挡柱安装凹槽内，所述螺钉挡柱一体构件的身部穿过所述通孔，所述螺钉挡柱一体构件的身部与所述通孔为螺纹连接。本发明的有益效果是：可以较好的避免挡柱上的密封件的磨损，防止产品漏油。
