Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically to a high-pressure, high-flow hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, eliminates transmission backlash, and provides smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] In the prior art, hydraulic cylinders generally require a control device to input hydraulic oil to work, and the hydraulic oil can drive the piston rod to reciprocate by pressing the piston.

[0004] During long-term use, metal debris may be present in the hydraulic oil supplied to the hydraulic cylinder. When this metal debris enters the cylinder along with the hydraulic oil, it may cause wear on the inner wall of the cylinder, thereby affecting the normal operation of the cylinder.

[0026] 1. In this utility model, by setting up a hydraulic oil filter element, a housing cover and a sealing plate, the housing cover and the sealing plate can be fixed by a positioning mechanism. Then, the hydraulic oil filter element can be sealed with the positioning ring and the sealing plate by the first sealing ring. Thus, the hydraulic oil can be filtered by the hydraulic oil filter element. At the same time, metal debris can be attracted by the magnetic block, thereby avoiding the metal debris from affecting the operation of the cylinder body.

[0027] 2. In this utility model, the positioning mechanism facilitates the rotation of the first gear by rotating the handwheel. Simultaneously, the meshing of the first gear with the first gear ring drives multiple first gears and multiple second bevel gears to rotate synchronously. Furthermore, the meshing of the second bevel gear with the first bevel gear drives the adjustment disc to rotate. Thus, the positioning block can be moved by pulling the rotating shaft and the adjustment rod. This facilitates the installation and fixing of the box cover and the filter box by the cooperation of the positioning block with the first positioning groove and the second positioning groove respectively.

[0028] 3. In this utility model, the support spring facilitates the limiting of the positioning block by the elastic force of the support spring, thereby preventing the box cover from loosening or falling off in the mounting groove;

[0029] 4. In this utility model, the hydraulic cylinder body, housing cover, sealing ring, hydraulic oil filter element, positioning mechanism and first oil supply pipe are arranged to facilitate the filtration of hydraulic oil through the hydraulic oil filter element. At the same time, the magnetic block can attract metal debris, thereby avoiding the metal debris from affecting the operation of the hydraulic cylinder body. This solves the problem in the prior art that the presence of metal debris in the hydraulic cylinder can affect the operation of the hydraulic cylinder. Attached Figure Description

[0038] like Figures 1-5As shown, this embodiment proposes a high-pressure, high-flow hydraulic cylinder, including a cylinder body 1, a housing cover 4, a sealing ring 7, a hydraulic oil filter element 8, a positioning mechanism, and a first oil delivery pipe 9.

The hydraulic oil filter element 8 is provided with a first sealing ring 11 between the box cover 4 and the sealing plate 5 of the filter box 2 respectively. The second sealing ring 12 is fixedly provided on the side wall of the sealing plate 5. After the box cover 4 and the sealing plate 5 are fixed by the positioning mechanism, the first sealing ring 11 can be used to seal the hydraulic oil filter element 8 between the positioning ring and the sealing plate 5 respectively. Thus, the hydraulic oil can be filtered by the hydraulic oil filter element 8. At the same time, the magnetic block 6 can be used to attract metal debris, thereby avoiding the metal debris from affecting the operation of the cylinder body 1.

[0039] Reference Figures 3-5 The positioning mechanism includes a first positioning groove 13, a second positioning groove 14, a positioning block 15, and a position adjustment mechanism. Multiple first positioning grooves 13 are provided on the side wall of the mounting groove 3, and multiple second positioning grooves 14 are provided on the side wall of the sealing disc 5. The multiple first positioning grooves 13 and multiple second positioning grooves 14 correspond one-to-one. The positioning block 15 is slidably disposed in the second positioning groove 14. A support spring 16 is fixedly disposed between the positioning block 15 and the bottom of the second positioning groove 14. The position adjustment mechanism is disposed in the second positioning groove 14 and is used to drive the positioning block 15 to adjust its position. The installation and fixation between the box cover 4 and the filter box 2 can be achieved by the cooperation of the positioning block 15 with the first positioning groove 13 and the second positioning groove 14 respectively.

[0040] Reference Figures 3-5The position adjustment mechanism includes an adjustment disc 17, an adjustment rod 18, and a rotating mechanism. The adjustment disc 17 is rotatably disposed between the bottom of the second positioning groove 14. A rotating shaft is rotatably disposed at the eccentric position of the adjustment disc 17. The adjustment rod 18 is hinged between the rotating shaft and the positioning block 15. The rotating mechanism is disposed on the cover 4 and is used to drive the adjustment disc 17 to rotate. The rotating mechanism includes a first cavity, a second bevel gear 20, and a synchronous rotating mechanism. The first cavity is opened on one side of the second positioning groove 14. A first bevel gear 19 is rotatably disposed on the side wall of the first cavity. A first connecting rod is fixedly disposed between the first bevel gear 19 and the adjustment disc 17. The second bevel gear 20 is rotatably disposed on the inner top wall of the first cavity and meshes with the first bevel gear 19. The synchronous rotating mechanism is disposed on the cover 4 and is used to drive the second bevel gear 20 to rotate. The synchronous rotating mechanism includes a second cavity, a first gear ring 22, and a handwheel 23. An annular opening is provided inside the cover 4. The second cavity contains a plurality of first gears 21 rotatably mounted therein. A second connecting rod is fixedly mounted between the first gears 21 and the adjacent second bevel gears 20. A first gear ring 22 is rotatably mounted in the second cavity and meshes with the first gears 21. A handwheel 23 is rotatably mounted on the cover 4. A drive rod is fixedly mounted between the handwheel 23 and the adjacent first gears 21, so that the rotation of the handwheel 23 can drive the first gears 21 to rotate. At the same time, the meshing of the first gears 21 and the first gear ring 22 drives the plurality of first gears 21 and the plurality of second bevel gears 20 to rotate synchronously. Then, the meshing of the second bevel gears 20 and the first bevel gears 19 can drive the adjusting plate 17 to rotate. Thus, the positioning block 15 can be moved by the rotating shaft and the adjusting rod 18. The positioning block 15 can be fixed by cooperating with the first positioning groove 13 and the second positioning groove 14 respectively.

[0041] In this embodiment, during use, the operator inserts one end of the hydraulic oil filter element 8 into the positioning ring, then inserts the cover 4 into the mounting groove 3 and the sealing disc 5 into the sealing port. The operator then rotates the handwheel 23, which drives the first gear 21 to rotate. Simultaneously, the meshing of the first gear 21 with the first gear ring 22 drives multiple first gears 21 and multiple second bevel gears 20 to rotate synchronously. The meshing of the second bevel gear 20 with the first bevel gear 19 drives the adjusting disc 17 to rotate. This allows the positioning block 15 to move via the rotating shaft and adjusting rod 18. The positioning block 15, in conjunction with the first positioning groove 13 and the second positioning groove 14, secures the cover 4 and the filter box 2. At this time, the first sealing ring 11 seals the hydraulic oil filter element 8 with the positioning ring and the sealing disc 5, allowing the hydraulic oil to be filtered by the hydraulic oil filter element 8. Simultaneously, the magnetic block 6 attracts metal debris, preventing it from affecting the operation of the cylinder body 1.
