Technical Field

[0001] The utility model belongs to the technical field of hydraulic oil cylinder disassembly and assembly, in particular to a hydraulic oil cylinder piston disassembly and assembly machine. Background Art

[0002] During use, hydraulic cylinders often fail due to seal wear, cylinder wear, inner wall scratches, inner wall corrosion, piston or piston rod scratches, etc.

[0003] At present, the disassembly and assembly of the cylinder piston (replacing the sealing ring, etc.) is generally carried out by manpower in cooperation with the hydraulic system of the scraper to extend the cylinder piston. In actual use, it is inconvenient to quickly and stably clamp hydraulic cylinders of different specifications, resulting in low applicability. Therefore, a hydraulic cylinder piston disassembly and assembly machine is needed to improve the above problem. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a hydraulic cylinder piston disassembly and assembly machine, which solves the problem of low applicability due to the inconvenience in quickly and stably clamping hydraulic cylinders of different specifications during actual use.

[0013] 1. The hydraulic cylinder piston disassembly and assembly machine is equipped with an operating table, a cylinder, a connecting rod, a splint, a sleeve and a fixing block. With the cooperation of the operating table, the cylinder, the connecting rod, the splint, the sleeve and the fixing block, the cylinder can be fixed on the operating table to facilitate the disassembly of the cylinder piston. At the same time, it only needs to control the distance between the four splints driven by the cylinder.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3As shown, the utility model provides a technical solution: a hydraulic oil cylinder piston disassembly and assembly machine, including a bottom plate 1, an operating table 2 is arranged on the bottom plate 1, and a cylinder 12 is arranged on the bottom plate 1. By arranging the bottom plate 1 and the cylinder 12, the bottom plate 1 plays a supporting and limiting role on the cylinder 12, thereby ensuring the stability of the cylinder 12 when in use, a sleeve 13 is arranged on the side of the output end of the cylinder 12, and a fixing block 16 is arranged under the operating table 2. Four pin shaft frames 17 are arranged on the sides of the sleeve 13 and the fixing block 16. By arranging the pin shaft frames The pin frame 17 enables the second rotating rod 18 of the first rotating rod 11 to be stably hinged and rotated in the pin frame 17. Four through holes 9 are opened on the operating table 2. The connecting rod 8 is overlapped in the through holes 9. A slider 15 is provided on the side of the connecting rod 8. A slide groove 14 is overlapped on the side of the slider 15. By setting the slide groove 14 and the slider 15, and the slide groove 14 and the slider 15 cooperate with each other, the slider 15 is prevented from deviating and falling during the movement, thereby ensuring the stability of the connecting rod 8 during movement.

[0021] The slide groove 14 is opened in the through hole 9, and a fixed rod 10 is provided under the connecting rod 8. A first rotating rod 11 is hinged in the fixed rod 10, and the other end of the first rotating rod 11 is hinged in the pin frame 17. A second rotating rod 18 is hinged in the fixed rod 10, and the other end of the second rotating rod 18 is hinged in the pin frame 17. The first rotating rod 11 and the second rotating rod 18 overlap, and a clamping plate 7 is provided at the other end of the connecting rod 8. By setting the connecting rod 8 and the clamping plate 7, the connecting rod 8 supports and limits the clamping plate 7, thereby ensuring that the clamping plate 7 will not shake randomly during the movement. There are anti-skid patterns 6. By setting the anti-skid patterns 6, the contact friction with the hydraulic cylinder can be increased. A support frame 3 is provided on the operating table 2. A disassembly hydraulic cylinder 5 is provided in the support frame 3. A disassembly head assembly 4 is provided at the output end of the disassembly hydraulic cylinder 5. By setting the disassembly head assembly 4, the disassembly head assembly 4 includes a screw rod, a connecting nut rod and a locating pin. With the mutual cooperation of the screw rod, the connecting nut rod and the locating pin, the connecting nut rod and the locating pin are driven to move back and forth during the rotation of the screw rod, so that the locating pin is positioned with the cylinder piston rod, so that the piston rod can be pulled out and the cylinder can be repaired.

[0022] The working principle of the utility model is:

[0023] When in use, first place the hydraulic cylinder to be processed on the operating table 2, then start the cylinder 12 to work, the cylinder 12 drives the sleeve 13 and the four pin frames 17 to move downward, the four pin frames 17 drive the four first rotating rods 11 to move in a direction close to each other, the four first rotating rods 11 drive the four fixed rods 10 to move in a direction close to each other, at this time the four second rotating rods 18 move in a direction close to each other, the four fixed rods 10 drive the four connecting rods 8 to move in a direction close to each other in the through holes 9;

[0024] The four connecting rods 8 drive the four clamps 7 to move to a position close to the hydraulic cylinder until the four clamps 7 are in close contact with the hydraulic cylinder to a limit position, and then the disassembly hydraulic cylinder 5 is controlled to drive the disassembly head assembly 4 to connect with the cylinder piston rod, and the disassembly hydraulic cylinder 5 is controlled to drive the cylinder piston rod to move upward and pull out, so that the cylinder can be repaired smoothly.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
