Detailed ways

Embodiments shown in Figure 1, Figure 2 and Figure 3, the hydraulic cylinder disassembly workbench of the present invention includes a work platform 1, an oil tank 2, two bottom plates 3, two beams 4, four V-shaped tooth plates 5, four screw rod 6 and four compression nuts 7, the oil groove 2 is arranged on the periphery of the working platform 1, the two bottom plates 3 are arranged on the top surface of the working platform 1 in parallel at intervals, and the four screw rods 6 are vertically arranged respectively At the two ends of the two bottom plates 3, the two beams 4 respectively penetrate the tops of the four screw rods 6, and the four compression nuts 7 are screwed on the top ends of the four screw rods 6, the Four V-shaped toothed plates 5 are respectively arranged on the top surfaces of the two bottom plates 3 and the bottom surfaces of the two beams 4 and the toothed surfaces are arranged facing each other.

Preferably, the top surface of the working platform 1 is provided with sliding grooves 11 in parallel at intervals, and the two bottom plates 3 are moved along the sliding grooves 11 by sliders and fastened by locking bolts.

Preferably, the workbench further includes a shut-off valve 21 , which is arranged on the side of the oil tank 2 and communicates with the oil tank 2 . When the hydraulic oil in the oil tank is full, the hydraulic oil can be discharged to the oil tank through the shut-off valve, so as to prevent the hydraulic oil from polluting the environment during the disassembly process of the hydraulic cylinder.

Preferably, the workbench further includes footings 8 provided on both sides of the bottom surface of the working platform 1 .

As shown in Figure 4 and Figure 5, usually the hydraulic cylinder mainly consists of a fork 91, a front end cover 92, a front end cover fixing bolt 93, a piston rod 94, a cylinder barrel 95, a piston, front and rear buffer sleeves, a rear end cover 96, and a rear end cover Fixing bolts 97 and seals, etc., hydraulic cylinder repair items generally include replacement of damaged parts, replacement of seals, chrome plating of the cylinder barrel, and chrome plating of the piston rod. To complete the above repair items, the hydraulic cylinder must be completely disassembled and the piston rod can be pulled out to complete. Therefore, when disassembling and assembling the hydraulic cylinder, first adjust the two bottom plates 3 on the working platform 1 to a suitable distance according to the length of the cylinder barrel 95 of the hydraulic cylinder and fasten them, and hoist the hydraulic cylinder to the V-shaped teeth on the two bottom plates 3. Then put the crossbeam 4 on the screw 6, the V-shaped toothed plate on the crossbeam 4 is stuck on the top surface of the hydraulic cylinder 95, screw the compression nut 7 on the top of the screw 6, so that the V-shaped toothed plate will The cylinder barrel 95 of the hydraulic cylinder is fixed and cannot be rotated by external force. At this point, you can turn the fork 91 counterclockwise to remove the fork 91; use an Allen wrench or an electric wrench to remove the fixing bolts 93 and 97 of the front end cover 92 and the rear end cover 96 of the hydraulic cylinder, and remove the front end cover 92 and the rear end cover 96. The remaining hydraulic oil in the hydraulic cylinder flows into the oil tank around the working platform 1 to reduce environmental pollution; pull out the piston rod 94, clean the various parts of the hydraulic cylinder, measure and replace damaged parts and seals, and the disassembly operation is completed . The installation operation of the hydraulic cylinder is opposite to the above steps. After all the hydraulic cylinders are installed, they are sent to the hydraulic laboratory for hydraulic test. After the test is passed, they can be shipped from the factory, so as to facilitate the disassembly and assembly of the hydraulic cylinder.
