Embodiment Construction
[0009] Such as figure 1 , 2 As shown, the described annular oil cylinder and its oil injection system include an oil cylinder, which is characterized in that: the described oil cylinder is an annular oil cylinder 1, and the annular oil cylinder 1 is arranged on the outer main shaft 5 of the double-set spindle system, and the annular oil cylinder 1 It is not connected to the oil pipe and is in a passive state when working. The outer main shaft 5 of the double-spindle system is set on the main shaft 7 through bearings. The annular oil cylinder 1 is provided with a connecting chuck 4. The oil filling valve 3 is arranged on the annular oil cylinder 1 and the connecting card. On the plate 4, the oil filling valve 3 is set correspondingly to the hydraulic oil chamber 2 of the annular oil cylinder 1, and the oil filling gun 91 of the oil filling device is set correspondingly to the oil filling valve 3. The afterbody of gun 91 links to each other with oil injection pipe 93. After th...

The invention relates to an annular cylinder and an oil injection system thereof, which comprise an annular cylinder 1 and are characterized in that: the annular cylinder 1 is arranged on a casing spindle 5 of a dual-casing spindle system, the casing spindle 5 is arranged on a spindle 7 through a bearing, a connection chuck 4 is arranged on the annular cylinder 1, an oil injection valve 3 is arranged on the annular cylinder 1 and the connection chuck 4 and arranged correspondingly to a hydraulic oil chamber 2 of the annular cylinder 1, an oil injection gun 91 of the oil injection device and the oil injection valve 3 are correspondingly arranged, the oil-injection gun 91 is connected with an oil injection propulsion device 8 through an oil gun end hinge pivot 92, and the end of the oil injection gun 91 is connected with an oil injection pipe 93. The oil suction and injection is realized when the annular cylinder stops working; when the annular cylinder rotates with the casing spindle, the oil injection is not necessary to rotate with the annular cylinder; the annular cylinder 1 is not connected with the oil pipe, thus working in a passive stage and effectively ensuring the required running; and the structure is simple and the operation is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of hydraulic oil cylinders and motion control thereof, in particular to an annular oil cylinder and an oil injection system thereof. Background technique [0002] The advantages of hydraulic transmission are: high power, high efficiency, low noise, safe and stable, highly integrated, etc. At present, the commonly used hydraulic transmission method is to drive the hydraulic pump to work through the motor, absorb oil from the fuel tank, and connect a series of hydraulic valves after the pressure oil is output from the hydraulic pump, and then connect to the actuator. By controlling the working state of the hydraulic valve, the actuator realizes the requested action. This transmission mode is difficult to meet the working condition that the executive oil cylinder needs to have rotary motion. In the design of CNC boring and milling machine for processing wind turbine hubs, an annular oil cylinder is required t...
