Preferably, the method comprises the following steps: the inside two relative pistons of cylinder body divide into two upper and lower cavities with the wall body in, the outside of going up the cavity is equipped with an M and pours into the joint, and the outside of lower cavity is equipped with an N filling opening and connects, M pours into the joint and N filling opening connects and all connects to outside hydraulic pressure station.
Preferably, the method comprises the following steps: an O-shaped sealing ring is arranged between the cylinder body and the piston rod, and an O-shaped sealing ring is arranged between the cylinder cover and the cylinder body, so that the sealing performance between the upper cavity and the lower cavity of the cylinder body and between the piston rod and the cylinder cover is ensured.
The utility model adopts the technical scheme that: hydraulic oil is injected into the upper cavity of the cylinder body through the upper end connector of the cylinder body, the piston rod is pushed to move downwards, and the main shaft pull rod is pushed through the lower end of the piston rod, so that the knife striking is completed; hydraulic oil is injected into the lower cavity of the cylinder body through the lower end connector of the cylinder body, the piston rod is pushed to move upwards, and the cutter retracting process is completed;
drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
The invention will be described in detail below with reference to the following drawings: as shown in fig. 1, a novel oil pressure unclamping cylinder comprises a cylinder body 2 with a cylinder cover 1, two piston rods 4 and 16 with pistons arranged oppositely from top to bottom are arranged in the cylinder body 2, an O-shaped sealing ring 7 is arranged between the two pistons, the upper piston rod 4 passes through the cylinder cover 1 to be connected with the pistons in the cylinder body 2, P, N two switches 5 and 6 arranged from top to bottom are arranged on one side edge of the upper piston rod 4, the two switches are arranged on a switch bracket 6 on the outer side, the bracket 6 is fixed on one side of the cylinder cover through a hexagon screw 11, a lower piston rod 16 passes through the bottom of the cylinder body 1 to be arranged in a flange 3 on the lower part, the flange 3 is connected with the cylinder body 2 through a hexagon socket screw 10, the bottom of the flange 3 is arranged on a box body through a hexagon socket screw 12, the two opposite pistons 4 and 16 in the cylinder body 2 divide the wall body into an upper cavity 17 and a lower cavity 18, an, the outside of lower cavity 18 is equipped with an N filling opening and connects 20, M filling opening connects 19 and N filling opening connects 20 all connects to outside hydraulic pressure station, be equipped with O type sealing washer 9 between cylinder body 2 and piston rod 4, 16, be equipped with O type sealing washer 8 between cylinder cap 1 and the cylinder body 2, guarantee the leakproofness between cylinder body 2 epicoele 17, lower cavity 18 and piston rod 4, 16 and the cylinder cap.
The utility model provides an oil pressure unclamping cylinder is applied to the mechanical device of vertical machining center main shaft unclamping tool changing, mainly comprises piston rod, cylinder body, cylinder cap, flange, acts on the piston rod through hydraulic oil, promotes the piston rod and accomplishes the unclamping process.
The specific implementation mode is as follows:
the utility model discloses piston rod, cylinder cap, cylinder body and O shape sealing washer form two upper and lower cavitys to there are two hydraulic pressure joints M, N to cylinder body side, two proximity switch P, Q of installation on the cylinder cap, connect and connect outside hydraulic pressure station with proximity switch.
When the hydraulic station starts to work, hydraulic oil enters the M joint, so that the upper cavity in the cylinder body is filled with oil to generate pressure to push the piston rod to move downwards, when a signal at the upper end of the piston rod is transmitted into the Q proximity switch, the oil is stopped being filled into the M joint through the hydraulic station, the pressure of the upper cavity is kept, meanwhile, the lower end of the piston rod pushes the main shaft pull rod open, and at the moment, the knife breaking is completed, and the tool can be changed simultaneously; after the tool changing is completed, hydraulic oil enters the N joint, so that the lower cavity in the cylinder body is filled with the oil and generates pressure, meanwhile, the M-end interface does not keep the pressure any more, the piston rod moves upwards at the moment, when a signal at the upper end of the piston rod is transmitted into the P proximity switch, the hydraulic oil is stopped being injected into the N interface through the external hydraulic station, the main shaft pull rod returns to the original position, the tool retracting is completed, and the whole tool beating and changing process is completed.
