我厂研制CYZZ-19磁座液压自动钻的液压进给系统设计成如图所示的全集成化结构,达到了体积小、重量轻和结构紧凑等目的。该结构主要由一个筒柱状缸筒16和各种液压元件有机地组装而成,在缸筒与各液压件之间钻有孔道,形成完整的液压回路系统。单相串激电机通过齿轮减速后,由轴2带动钻轴10作旋转运动。与齿轮3连接的凸轮4通过顶杆5、摇臂7迫使柱塞8作往复运动,完成泵油动作。进刀时,转阀15中相互垂直的两径向孔道分别与油道a、b连通,凸轮14将与转阀连锁的可控单向阀1顶开。压力油便经油道a、b顶开单向阀13(钢
Our factory developed CYZZ-19 hydraulic seat hydraulic hydraulic drill system designed as shown in the fully integrated structure, reached a small size, light weight and compact structure and so on. The structure is mainly composed of a cylindrical cylinder 16 and various hydraulic components organically assembled, the bore between the cylinder and the hydraulic components drilled to form a complete hydraulic circuit system. After the single-phase series motor is decelerated by the gear, the shaft 2 drives the drilling shaft 10 to rotate. The cam 4 connected with the gear 3 is driven by the plunger 5 and the rocker arm 7 to reciprocate the plunger 8 to complete the pumping action. In the process of feeding, two radial channels perpendicular to each other in the rotary valve 15 are respectively communicated with the oil passages a, b, and the cam 14 will open the controllable one-way valve 1 interlocked with the rotary valve. Pressurized oil through the oil a, b top open check valve 13 (steel
