The invention relates to the technical field of jacks, and discloses jack convenient combination and installation equipment which comprises a base, a fixing table and two supporting rods are welded to the top of the base, a fixing plate is slidably connected between the two supporting rods, a clamping plate is welded to the tops of the two fixing plates, and an air cylinder is always arranged above the clamping plate; a lubricating mechanism is welded to the bottoms of the two fixing plates, and an accurate shaft mechanism is arranged in the fixing table. The piston rod penetrates through the center of the movable disc, makes contact with the lubricating ball plug and extrudes the lubricating ball plug in the opposite direction to open the oil outlet pipe, and at the moment, the extruded lubricating oil in the feeding cavity is sprayed to the piston rod from the oil outlet pipe, so that the friction force on the side face of the piston rod is reduced; therefore, the effect of preventing rigid friction between the piston rod and the cylinder body when the piston rod is guided into the cylinder body is achieved, the piston rod is prevented from being scratched, and the quality of the assembled jack is improved.
本发明涉及千斤顶技术领域,且公开了一种千斤顶便捷组合安装设备,包括底座,所述底座的顶部焊接有固定台两个支撑杆,两个所述支撑杆之间均滑动连接有固定板,两个所述固定板的顶部焊接有夹板,所述夹板的上方始终有气缸,两个所述固定板的底部焊接有润滑机构,所述固定台的内部开设有确轴机构。通过气缸继续向下移动会将活塞杆挤出夹板,活塞杆与从活动盘中心穿过,与润滑球塞接触,会往相背的方向挤压润滑球塞,将出油管打开,此时上料腔内被挤压的润滑油会从出油管喷向活塞杆,减小活塞杆侧面的摩擦力,从而达到了防止将活塞杆导入缸体内时,活塞杆与缸体发生刚性摩擦的效果,避免了活塞杆被划伤,提高了组装后的千斤顶的质量。
