气缸套车削多瓣弹性胀紧装置
本技术提供的是机械领域的工具,具体地说是气缸套车削多瓣弹性胀紧装置。
技术介绍
传统的内燃机气缸缸套加工是将缸套插入到套杆上进行加工,而套杆的架构是在胀缩头内通过螺纹连接有胀芯,在胀芯的端部设有内六孔的盲孔,进行胀紧时,用直角的内六角扳手拧动胀芯,使被加工的缸套与胀缩头锁紧,进行缸套外表面加工。存在的缺点是:用手工操作胀紧胀缩头,劳动强度大,而且扳手容易甩出,伤人,装上缸套与取下缸套用时长,所以加工效率低。
技术实现思路
为了使气缸套加工过程胀紧,本技术提供了气缸套车削多瓣弹性胀紧装置。该装置通过油压机动作,使胀芯伸出或缩回,胀紧或取下气缸套,解决气缸套车削加工的技术问题。本技术解决技术问题所采用的方案是:在缸套套管内穿有推拉杆,缸套套管头端设有胀套,胀套内设有胀套孔,在胀套上环周设有胀缩孔,并装有钢丝胀簧,胀缩孔前端设有通到头的胀缝,在与胀套相距的位置设有定位台肩,定位台肩与胀套之间设有防振环,缸套套管内端通过连接套与车床的卡盘连接;在胀套孔内所装的胀芯的定位套通过螺母固定在推拉杆端,推拉杆通向车床一侧装有液压缸,液压缸通过输油管与液压泵站连接。积极效果,由于本技术能够使机械胀紧气缸套车削加工。具有定位准确,套紧和退出速度快,节省人工,加工效率高的优点。适宜作为气缸套切削装置使用。附图说明图1为本技术半剖结构图;图2为本技术胀套结构图;图3为本技术胀套外视图;图4为本技术胀套立体图。图中,1.缸套套管,2.推拉杆,3.液压缸,4.车床,5.卡盘,6.连接套,7.定位台肩,8.防振环,9.胀套,9.1.胀缩孔,9.2.胀缝,9.3.胀簧 ...
