Description

Technical Field

[0001] The invention belongs to the technical field of oil cylinder piston rods, in particular to an assembly device and an assembly method for an oil cylinder piston rod. Background Art

[0002] The hydraulic cylinder is the core actuator of the hydraulic support. It is mainly composed of two parts: the cylinder barrel and the piston rod. During assembly, the seal is first installed on the finely processed piston rod, and then the piston rod with the seal is pushed into the cylinder barrel to achieve the sealed assembly of the cylinder barrel and the piston rod, and ensure the sealing of each chamber and the cylinder barrel;

[0003] In the existing oil cylinder piston rod assembly process, applying lubricating oil is an important step, which helps to reduce the friction between the piston rod and the cylinder body. Generally, after applying lubricating oil to the piston rod, the piston rod is left to stand for a period of time to allow excess lubricating oil to drip naturally, thereby removing all excess lubricating oil;

[0004] During the assembly process of the cylinder piston rod, normal wear will occur due to the relative movement between parts. These wear will produce metal particles. These metal particles will fall into the lubricating oil together with dust and impurities in the environment, and then flow with the lubricating oil and deposit in the lubricating oil. This causes the dripping excess lubricating oil to contain metal particles and impurities. If these substances fall directly on the top of the machine body or other non-lubricated areas, they may cause environmental pollution and affect the cleanliness of the production environment. Long-term accumulation may also lead to oil accumulation, increasing the difficulty of cleaning and maintenance.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] The centering assembly 7 is installed on the top of the machine body 1, and includes an electric slide rail 101 symmetrically fixed on the top of the machine body 1, the top of the electric slide rail 101 is slidably connected to a centering plate 102, the top of the centering plate 102 is symmetrically fixed with a slide bar 103, the outer wall of the slide bar 103 is symmetrically slidably connected to a centering block 104, and a centering pad 105 is fixed on the side where the two centering blocks 104 are close to each other;

[0039] The collecting assembly 8 is installed on the inner side of the centering block 104, and includes a collecting box 201 arranged on the inner side of the centering block 104. A filter plate 202 is fixed on the inner side of the collecting box 201. A filter hole 203 is opened on the top of the filter plate 202. Oil flow grooves 204 are opened at equal distances on the sides of the two centering blocks 104 that are close to each other.

[0040] The driving assembly 9 is installed at the bottom of the collecting box 201, and is used to drive the two centering blocks 104 to slide in directions corresponding to each other.

[0041] Specifically, since applying lubricating oil is an important step in the existing oil cylinder piston rod assembly process, it helps to reduce the friction between the piston rod and the cylinder body 3. Generally, after the lubricating oil is applied to the piston rod, the piston rod is left to stand for a period of time to allow excess lubricating oil to drip naturally, thereby removing all excess lubricating oil. However, during the assembly process of the oil cylinder piston rod, normal wear will occur due to the relative movement between parts. These wears will produce metal particles. These metal particles will fall into the lubricating oil together with dust and impurities in the environment, and then flow with the lubricating oil and be deposited in the lubricating oil. However, the dripping excess lubricating oil may contain metal particles and impurities. If these substances fall directly on the top of the body 1 or other non-lubricated areas, they may cause environmental pollution and affect the cleanliness of the production environment. Long-term accumulation may also lead to accumulation of oil stains, increasing the difficulty of cleaning and maintenance.
