Detailed Description
The present utility model will be further specifically described below by way of examples in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be noted that, the terms "upper", "top", "bottom", and the like in the embodiments are described according to the orientations shown in the drawings in the specification, and do not represent the limitation of the orientations of the present utility model in actual use.
Examples: 1-2, referring to fig. 1-2, including cylinder body 1, piston passageway 2 has been seted up along vertical inwards to the top surface of cylinder body 1, and piston passageway 2 holds and has piston rod 3, and the opening part threaded connection of piston passageway 2 has and is equipped with protecgulum 4, and piston rod 3 can follow piston passageway 2 and remove, and can outwards stretch out. Specifically, the bottom end of the piston rod 3 is provided with a step, the outer diameter of the step is in clearance fit with the piston channel 2, and the outer diameter of the opposite upper part of the piston rod 3 is in clearance fit with the inner diameter of the central opening of the front cover 4.
In the structure, the bottom end of the piston channel 2 is communicated with the air inlet 5, the air inlet 5 is externally connected with an air source, the air inlet of the air source is controlled by the electromagnetic valve, and when the air inlet 5 is in air, the air pressure pushes the piston rod 3 to extend outwards. An oil inlet 6 is communicated with the side surface of the opposite upper part of the piston channel 2, and an oil inlet channel 7 communicated with the oil inlet 6 is also arranged on the side surface of the front cover; the piston rod 3 is provided with an oil outlet cavity 8 inwards along the axial direction from the top end, the opposite bottom end of the oil outlet cavity 8 is provided with an oil inlet hole 9 in a extending mode to the side face, and when the piston rod 3 moves up to the limit position, the oil inlet hole 9 is in butt joint with the oil inlet channel 7 to realize oil way communication.
In order to facilitate the connection of the oil passage more conveniently, in this embodiment, a ring groove 10 is formed on the piston rod 3 at the position of the oil inlet hole 9 along the circumferential direction, so that the lubricating oil enters the oil outlet cavity 8 from the oil inlet hole 9 after passing through the oil inlet channel and entering the ring groove 10. Similarly, the oil inlet passage 7 on the front cover 4 may be provided in the same manner.
In order to ensure sealing, a first sealing ring 11 is embedded at the opposite bottom of the piston rod 3 (a groove is formed in the side surface of the step at the bottom of the piston rod, and the first sealing ring is embedded in the groove), and the first sealing ring 11 is matched with the inner wall of the piston channel 2; the inner wall of the front cover 4 is embedded with a second sealing ring 12, and the second sealing ring 12 is matched with the outer wall of the piston rod 3.
