Description
Technical Field
The utility model relates to the technical field of hydraulic cylinder maintenance equipment, in particular to a hydraulic cylinder piston rod sealing assembly device.
Background
The hydraulic cylinder is used as a hydraulic actuating mechanism of linear reciprocating motion, high-pressure oil is required to be filled in a cylinder body frequently during the working of the hydraulic cylinder, a piston rod is pushed to move, and the piston rod is frequently stretched to cause friction loss between a piston rod sealing ring and the cylinder body to cause leakage in the hydraulic cylinder. When the piston rod sealing ring is replaced, the piston rod sealing ring is influenced by large sealing cross section area, small sealing elasticity and the like, and is completely assembled on the piston rod, so that the labor is wasted. The assembly of current sealing washer all adopts the manual work to push up the sealing washer through the screwdriver and move down to the piston rod seal groove in, and this kind of mounting means wastes time and energy. Therefore, the design of the hydraulic cylinder piston rod sealing assembly device is urgent to solve the problem that the assembly of the existing piston rod sealing ring is time-consuming and labor-consuming.
Disclosure of Invention
Aiming at the problems existing in the prior art, the utility model aims to provide a sealing assembly device for a piston rod of a hydraulic cylinder.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a sealed assembly quality of pneumatic cylinder piston rod, includes sealed guide table and application of force ring, sealed guide table adopts the frustum shape structure, and sealed guide table lower part stretches into in the cylinder body of pneumatic cylinder, and sealed guide table bottom is located piston rod seal groove department, and sealed guide table is last to be overlapped and is equipped with the application of force ring.
Specifically, the bottom of the sealing guide table is propped against the inside of the cylinder body, the sealing ring is sleeved on the sealing guide table, and the facility force circular ring is sleeved on the sealing guide table and above the sealing ring.
Specifically, the force application circular ring uniformly presses down the sealing ring, and the inner wall of the sealing ring is moved into the sealing groove of the piston rod along the outer wall of the sealing guide table.
Specifically, lubricating oil is smeared on the outer wall of the sealing guide table.
The utility model has the following beneficial effects:
the hydraulic cylinder piston rod sealing assembly device designed by the utility model is simple and practical, the force application ring is uniformly stressed, the sealing ring is completely pressed to the sealing groove, the surface is coated with lubricating oil, and the hydraulic cylinder piston rod sealing assembly device is very easy to install after sealing and lubrication; the installation is simple and practical, has showing the promotion to assembly quality and safety efficiency, improves the maintenance efficiency of pneumatic cylinder.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described in further detail below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in figures 1-3, the sealing assembly device for the piston rod of the hydraulic cylinder comprises a sealing guide table 1 and a force application ring 2, wherein the sealing guide table 1 adopts a frustum-shaped structure, the lower part of the sealing guide table 1 stretches into a cylinder body 3 of the hydraulic cylinder, the bottom of the sealing guide table 1 is positioned at a sealing groove 5 of the piston rod, and the force application ring 2 is sleeved on the sealing guide table 1.
The bottom of the sealing guide table 1 is propped against the inside of the cylinder body 3, the sealing guide table 1 is sleeved with a sealing ring 6, and the sealing guide table 1 is sleeved with a facility force circular ring 2 above the sealing ring 6. The force application circular ring 2 uniformly presses down the sealing ring 6, and the inner wall of the sealing ring 6 moves into the sealing groove 5 of the piston rod against the outer wall of the sealing guide table 1.
The outer wall of the sealing guide table 1 is smeared with lubricating oil, and the lubricating oil adopts glycerol.
In order to ensure the assembly integrity and the assembly rapidity, the utility model combines the cylindrical shape of the piston rod 4 and specially makes an irregular frustum-shaped device to install the sealing ring 6 of the piston rod 4. The design is simple and practical, and application of force ring 2 atress evenly, sealing washer 6 is perfect presses piston rod seal groove 5. And glycerin is smeared on the surface, and the sealing and lubrication are easy to install. The installation is simple and practical, has apparent promotion to assembly quality and safety efficiency.
The present utility model is not limited to the above embodiments, and any person who can learn the structural changes made under the teaching of the present utility model can fall within the scope of the present utility model if the present utility model has the same or similar technical solutions.
The technology, shape, and construction parts of the present utility model, which are not described in detail, are known in the art.
