Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder oil seal disassembly technology, and in particular to a hydraulic cylinder oil seal disassembly tool. Background Technology

[0002] Hydraulic cylinders, as common mechanical devices, are typically composed of a cylinder barrel, an oil seal (sealing element), a piston rod, and a connecting part installed at the end of the piston rod. The oil seal can prevent hydraulic oil from leaking from the inside of the cylinder to the outside, avoiding waste of the working medium, preventing environmental pollution and equipment failure caused by leakage, and also preventing external air, moisture and other impurities from entering the cylinder.

[0003] Currently, most methods for disassembling oil seals involve using a hammer to strike the oil seal and then disassembling the oil seal inside the cylinder. However, when striking the oil seal, because the oil seal and piston rod are installed close together, and the hammer is driven by hand, the hammer inevitably hits the piston rod, which can easily cause dents or damage to the piston rod, rendering it unusable. To address this issue, we propose a new oil seal disassembly tool for cylinders. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for disassembling the oil seal of a hydraulic cylinder, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydraulic cylinder oil seal removal tool includes a base, a cylinder placement seat fixedly connected to the upper surface of the base, a cavity opened inside the cylinder placement seat, a hydraulic cylinder body placed above the cylinder placement seat, a piston rod inside the hydraulic cylinder body, an oil seal body inside the hydraulic cylinder body, a support plate fixedly connected to the upper surface of the base, a top plate fixedly connected to the upper surface of the support plate, a hydraulic cylinder fixedly installed inside the top plate, a hydraulic push rod fixedly installed at the output end of the hydraulic cylinder, a lifting plate fixedly connected to the output end of the hydraulic push rod, and an ejector ring made of rubber fixedly connected to the bottom surface of the lifting plate.

[0007] In a further embodiment, a control button is fixedly installed on the upper surface of the base, and an annular limiting plate is fixedly connected to the upper surface of the cylinder placement seat.

[0008] In a further embodiment, a reinforcing triangular plate is fixedly connected to the front of the support plate, and the upper surface of the reinforcing triangular plate is connected to the bottom surface of the top plate.

[0009] In a further embodiment, an indicator light is fixedly installed on the front of the top plate, and an oil seal collection box is fixedly connected to the upper surface of the base.

[0010] In a further embodiment, two sets of fixing columns are fixedly connected to the upper surface of the top plate, and a reinforcing ring is fixedly connected to the top of the two sets of fixing columns. The inner ring of the reinforcing ring is connected to the outer surface of the hydraulic cylinder.

[0011] In a further embodiment, two L-shaped positioning plates are fixedly connected to the bottom surface of the base, and a set of positioning holes are provided on the upper surface of each of the two L-shaped positioning plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first features a cylinder placement seat, which allows workers to easily place the cylinder body. Then, a hydraulic cylinder and a hydraulic push rod are installed. These components can drive the lifting plate and the ejector ring downwards, allowing the ejector ring to quickly eject the oil seal inside the cylinder body. Furthermore, the rubber material of the ejector ring effectively prevents wear and damage to the piston rod. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a tool for disassembling the oil seal of a hydraulic cylinder includes a base 1. A cylinder placement seat 2 is fixedly connected to the upper surface of the base 1. A cavity 3 is opened inside the cylinder placement seat 2. A hydraulic cylinder body 4 is placed above the cylinder placement seat 2. A piston rod 5 is provided inside the hydraulic cylinder body 4. An oil seal body 6 is provided inside the hydraulic cylinder body 4. A support plate 7 is fixedly connected to the upper surface of the base 1. A top plate 8 is fixedly connected to the upper surface of the support plate 7. A hydraulic cylinder 9 is fixedly installed inside the top plate 8. A hydraulic push rod 10 is fixedly installed at the output end of the hydraulic cylinder 9. A lifting plate 11 is fixedly connected to the output end of the hydraulic push rod 10. An ejection ring 12 is fixedly connected to the bottom surface of the lifting plate 11. The ejection ring 12 is made of rubber. The cylinder placement seat 2 allows workers to easily place the hydraulic cylinder body 4. The hydraulic cylinder 9 can drive the hydraulic push rod 10 to move the lifting plate 11 and the ejection ring 12 up and down, so that the ejection ring 12 can quickly eject the oil seal body 6 inside the hydraulic cylinder body 4.

[0023] A control button 13 is fixedly installed on the upper surface of the base 1. An annular limiting plate 14 is fixedly connected to the upper surface of the cylinder placement seat 2. A reinforcing triangular plate 15 is fixedly connected to the front of the support plate 7. The upper surface of the reinforcing triangular plate 15 is connected to the bottom surface of the top plate 8. An indicator light 16 is fixedly installed on the front of the top plate 8. An oil seal collection box 17 is fixedly connected to the upper surface of the base 1. The annular limiting plate 14 can play a good limiting effect when the cylinder body 4 is placed on the cylinder placement seat 2. The reinforcing triangular plate 15 can reinforce the middle of the support plate 7 and the top plate 8, so that the connection between the top plate 8 and the support plate 7 can be more secure. The oil seal collection box 17 can facilitate the collection of the disassembled oil seal body 6 by the staff.

[0024] Two sets of fixing columns 18 are fixedly connected to the upper surface of the top plate 8. The top of the two sets of fixing columns 18 are fixedly connected to a reinforcing ring 19. The inner ring of the reinforcing ring 19 is connected to the outer surface of the hydraulic cylinder 9. Two L-shaped positioning plates 20 are fixedly connected to the bottom surface of the base 1. A set of positioning holes 21 are opened on the upper surface of the two L-shaped positioning plates 20. The hydraulic cylinder 9 can be reinforced by the fixing columns 18 and the reinforcing ring 19, which can make the hydraulic cylinder 9 more stable during operation. The L-shaped positioning plates 20 and the positioning holes 21 can facilitate the workers to fix the base 1 to the ground.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the operator first uses the L-shaped positioning plate 20 and positioning hole 21 to fix the base 1 to the ground and connect the device to an external power source. Then, the operator places the cylinder body 4 on top of the cylinder placement seat 2. After the cylinder body 4 is placed, the operator uses the control button 13 to start the hydraulic cylinder 9 and hydraulic push rod 10. The hydraulic cylinder 9 and hydraulic push rod 10 drive the lifting plate 11 and the ejection ring 12 to descend, thereby causing the ejection ring 12 to push the oil seal body 6 inside the cylinder body 4 downward, thus pushing the oil seal body 6 inside the cylinder body 4 into the cavity 3. The above is the complete operation procedure of this device.
