具体实施方式 Detailed ways
实施例一：如图1所示，一种液压多回路可旋转接头，包括一设置在机床上的转轴1，所述转轴1的一端侧壁上间隔设置有若干个环形凹槽12，所述环形凹槽12外用轴承4套设有轴套3，所述轴套3内设置有隔离每个环形凹槽的密封圈31，所述轴套3侧壁上设置有数量与环形凹槽数量相等的注油孔，所述注油孔分别连接液压油管5，所述转轴1的另一端连接有液压夹具2，所述转轴1内沿轴向设置有数量与环形凹槽数量相等的通孔11，所述环形凹槽12分别联通一个通孔11的一端，所述通孔11的另一端与液压夹具2相连通并为液压夹具供油。 Embodiment 1: As shown in Figure 1, a hydraulic multi-circuit rotatable joint includes a rotating shaft 1 arranged on a machine tool, and a plurality of annular grooves 12 are arranged at intervals on the side wall of one end of the rotating shaft 1, and the Annular grooves 12, bearings for external use, 4 sleeves are provided with shaft sleeves 3, and sealing rings 31 are arranged in the shaft sleeves 3 to isolate each annular groove. The oil injection holes are respectively connected to the hydraulic oil pipes 5, and the other end of the rotating shaft 1 is connected to the hydraulic clamp 2, and the through holes 11 whose number is equal to the number of the annular grooves are arranged in the axial direction of the rotating shaft 1, so that The annular grooves 12 communicate with one end of a through hole 11 respectively, and the other end of the through hole 11 communicates with the hydraulic clamp 2 and supplies oil for the hydraulic clamp.
工作时，液压缸通过轴套上的液压油管对转轴内进行注油，运行时，转轴告诉旋转，轴套不转，液压油注入到环形凹槽内，再分别注入到各自连通的通孔内，对液压夹具供油。 When working, the hydraulic cylinder injects oil into the rotating shaft through the hydraulic oil pipe on the shaft sleeve. When running, the rotating shaft rotates at a high speed and the sleeve does not rotate. The hydraulic oil is injected into the annular groove, and then injected into the through holes connected to each other. Supply oil to hydraulic clamps.
