At the same time, the hydraulic oil exits from the second working chamber 63 of the second cylinder 61, passes through the second connection port B and the oil return port T, and returns to the oil tank 1, thereby allowing the first piston rod 52 and the connecting plate 3 to move forward.
When the three-position four-way reversing valve 10 is located at the second working position, the oil inlet P is communicated with the second connecting port B, and the oil return port T is communicated with the first connecting port A. At this time, the hydraulic oil enters the second working chamber 63 of the second cylinder body 61 from the oil inlet P through the second connecting port B, thereby pushing the second piston rod 62 to move backward, the spring 82 is released, the pressing block 81 is expanded in the radial direction, the processed workpiece is loosened, and at this time, the connecting plate 3 moves backward along with the second piston rod 62. Meanwhile, the hydraulic oil is discharged from the first working chamber 53 of the first cylinder 51, passes through the first connection port a and the oil return port T, and returns to the oil tank 1, thereby allowing the second piston rod 62 and the connecting plate 3 to move backward.
Referring to fig. 6, in some embodiments, an auxiliary oil return path is further provided between the first working chamber 53 of the first cylinder 51 and the oil tank 1, and the auxiliary oil return path is provided with the check valve. The auxiliary oil return path is used for assisting the first working cavity 53 of the first cylinder body 51 in draining oil, and the oil return rate can be increased. The check valve is opened when the first working chamber 53 is drained of oil and closed when no drainage of oil is required to prevent oil leakage.
