Abstract
The utility model discloses an ultra-thin auto-lock hydraulic nut, including the hydro-cylinder, be equipped with the piston in the hydro-cylinder, be equipped with the oil filler point in the piston, the contact surface of piston and hydro-cylinder is equipped with the sealing ring, and the piston upper surface is higher than the hydro-cylinder upper surface, and the part outside that the piston exceeds the hydro-cylinder is equipped with from the catch and is used for carrying out the pressurize to the hydro-cylinder. Through establish from the catch outside hydro-cylinder and piston, can effectively carry out the pressurize to hydro-cylinder inside, prevent that the unstable condition of pressure from taking place.
Description
Technical Field
The utility model relates to the field of machinary, specifically an ultra-thin auto-lock hydraulic nut.
Background
The hydraulic nut has the working principle that external force is directly applied to the bolt by using the hydraulic oil cylinder, the bolt with the applied force is stretched in the elastic deformation area, and the bolt is stretched and then screwed with the locking ring on the hydraulic nut, so that the bolt can be locked at the stretched position by the locking ring, the pressure of the previous hydraulic nut cannot be locked, and the pressure can not be maintained, so that the used workpieces cannot be disassembled, the working efficiency is seriously affected, and therefore certain improvement is needed on the basis before.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses an ultra-thin auto-lock hydraulic nut.
The technical scheme of the utility model is that: the ultrathin self-locking hydraulic nut comprises an oil cylinder, wherein a piston is arranged in the oil cylinder, an oil filling hole is formed in the piston, a sealing ring is arranged on the contact surface of the piston and the oil cylinder, the upper surface of the piston is higher than the upper surface of the oil cylinder, and a self-locking ring is arranged on the outer side of the part, higher than the oil cylinder, of the piston and used for maintaining pressure of the oil cylinder.
Further, the oil hole of the ultrathin self-locking hydraulic nut is connected with an external manual pump through an oil pipe.
Further, the upper surface of the self-locking ring is higher than the upper surface of the piston.
The utility model discloses an useful part: through establish from the catch outside hydro-cylinder and piston, can effectively carry out the pressurize to hydro-cylinder inside, prevent that the unstable condition of pressure from taking place.
Drawings
Fig. 1 is a schematic structural view of the present invention;
wherein: 1. the oil cylinder 2, the piston 3, the self-locking ring 4, the oil filling hole 5 and the sealing ring.
Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in fig. 1, the ultrathin self-locking hydraulic nut comprises an oil cylinder 1, a piston 2 is arranged in the oil cylinder 1, an oil filling hole 4 is arranged in the piston 2, a sealing ring 5 is arranged on a contact surface of the piston 2 and the oil cylinder 1, the upper surface of the piston 2 is higher than the upper surface of the oil cylinder 1, a self-locking ring 3 is arranged on the outer side of the part, higher than the oil cylinder 1, of the piston 2 and used for maintaining pressure of the oil cylinder 1, the upper surface of the self-locking ring 3 is higher than the upper surface of the piston 2, and the ultrathin self-locking hydraulic nut oil filling hole.
Install ultra-thin auto-lock hydraulic nut to the roller on, connect manual pump and oil pipe, lift east manual pump handle from top to bottom, go up the pressure, the manual pump manometer output pressure of visualing slowly rises, stop the input pressure when reaching the required pressure of work, rotatory self-locking ring locking hydro-cylinder pressurize, the oil pressure is unloaded to the manual pump, it carries out pressure fastening to hydraulic nut from the oil filler point to connect the manual pump, treat that the self-locking ring can not hard up the time stop to push up, loosen the self-locking ring with the driving lever and screw down.
Claims (3)
1. Ultra-thin auto-lock hydraulic nut, its characterized in that: the oil cylinder is characterized by comprising an oil cylinder, a piston is arranged in the oil cylinder, an oil filling hole is formed in the piston, a sealing ring is arranged on the contact surface of the piston and the oil cylinder, the upper surface of the piston is higher than the upper surface of the oil cylinder, and a self-locking ring is arranged on the outer side of the part, higher than the oil cylinder, of the piston and used for maintaining pressure of the oil cylinder.
2. The ultra-thin self-locking hydraulic nut of claim 1, characterized in that: the ultrathin self-locking hydraulic nut oil injection hole is connected with an external manual pump through an oil pipe.
